METHOD, APPARATUS, SYSTEM, TERMINAL AND ACCESS NETWORK DEVICE FOR COMMUNICATION [001] This application claims priority for Chinese Patent Application No. 201610875317.9, filed at the Chinese Patent Office on September 30, 2016 and entitled METHOD, APPARATUS, AND SYSTEM, TERMINAL, AND ACCESS NETWORK DEVICE FOR COMMUNICATION, which is incorporated herein by reference in its entirety.
TECHNICAL FIELD [002] The present invention relates to the field of communication technologies and, in particular, to a method, apparatus, system, terminal and access network device for communication.
FUNDAMENTALS [003] To ensure the quality of traffic, an end-to-end quality of service mechanism (English: Quality of Service, QoS for short) is generally used in an existing Long Term Evolution system (English: Long Term Evolution , LIE for short). In this mechanism, when a terminal initiates traffic whose QoS needs to be ensured, a dedicated carrier must be established for the terminal, in order to transmit traffic data.
[004] The dedicated carrier includes a radio carrier between the terminal and an evolved NodeB (English: evolved NodeB, eNB for short) and a terrestrial channel between the eNB and a network-side device. A process for establishing the dedicated carrier is as follows: When initiating traffic, the terminal first interacts with an application server using a standard carrier. The application server triggers a role rules function unit
Petition 870190068488, of 7/19/2019, p. 7/157
2/138 policy and charging (English: Policy and Charging Rules Function, PCRF for short) to generate a QoS parameter, and notify a mobility management entity (English: Mobility Management Entity, MME for short) of the generated QoS parameter . Thus, MME sends the QoS parameter to eNB. After receiving the QoS parameter, eNB establishes the dedicated carrier based on the received QoS parameter. The terminal can then send traffic data on the dedicated dedicated carrier.
[005] However, the terminal must wait for the completion of a QoS parameter allocation process, and can send traffic data only after the dedicated carrier is established based on the QoS parameter. Therefore, an initial speed of data transmission of uplink traffic is relatively low and a requirement to reduce traffic latency cannot be satisfied.
SUMMARY [006] To solve a problem in the prior art that an initial data transmission speed of uplink traffic is relatively low, embodiments of the present invention provide a method, apparatus, system, terminal and an access network device for communication. The technical solutions are as follows:
[007] According to a first aspect, an embodiment of the present invention provides a method for communication, wherein the method includes:
before starting a traffic, receive, through a terminal, the first QoS information; and when starting traffic, send data from the terminal
Petition 870190068488, of 7/19/2019, p. 8/157
3/138 traffic based on the first QoS information for using a radio resource that is configured by an access network device for traffic, where the radio resource is configured by the access network device in the second QoS information , and both the first QoS information and the second QoS information are configured by a core network control plan device for terminal traffic before the terminal starts traffic.
[008] In accordance with this embodiment of the present invention, before the terminal initiates traffic, the QoS information (including the first QoS information and the second QoS information) is allocated to the terminal, and the allocated QoS information is sent to the terminal and the access network device. When initiating traffic, the terminal can send data directly by using the radio resource that is configured by the access network device based on the allocated QoS information. In other words, the access network device can configure the radio resource for the terminal based on the QoS information that is allocated in advance before traffic starts, without waiting for authorized QoS information to be allocated by a network device. core and activated when the terminal initiates traffic, and the terminal can send traffic data based on the corresponding QoS information, by using the configured radio resource, so that a time for the terminal's traffic to start can be shortened.
[009] In a first possible implementation of the first aspect, if the access network device pre-configures, based on the second QoS information, a radio resource for a group of data packets corresponding to the traffic,
Petition 870190068488, of 7/19/2019, p. 9/157
4/138 when initiating traffic, the terminal can send traffic data by directly using the radio resource pre-configured by the access network device.
[0010] In a second possible implementation of the first aspect, if the access network device does not pre-configure, based on the second QoS information, a radio resource for a group of data packets corresponding to the traffic, when initiating the traffic, the terminal can request the access network device to configure a radio resource for traffic and then send traffic data by using a radio resource configured by the access network device. Therefore, in this implementation, the method also includes: sending, through the terminal, QoS request information to the access network device, so that the access network device configures a radio resource for the terminal traffic based on QoS request information.
[0011] The first QoS information includes at least one of the first pre-authorized QoS information and reflective characteristic information, and the reflective characteristic information includes a traffic downlink QoS parameter and indication information that is used for indicate an ability to obtain an uplink QoS parameter in the downlink QoS parameter of the traffic. In this embodiment of the present invention, the pre-authorized QoS information (including the first pre-authorized QoS information and the second pre-authorized QoS information in the following specification) is proactively configured by the core network control plan device for the terminal with based on subscription information
Petition 870190068488, of 7/19/2019, p. 10/157
5/138 from the terminal or based on common traffic (such as email or Taobao).
[0012] With reference to the second possible implementation, in a third possible implementation, the QoS request information includes uplink QoS information. If the first traffic QoS information received by the terminal includes both the first pre-authorized QoS information and the traffic reflective characteristic information, the terminal can select, depending on actual needs, which QoS information is used to request a resource radio. In other words, the uplink QoS information can include at least a portion of the first pre-authorized QoS information, to request that the access network device configure a radio resource based on the pre-authorized QoS information, or the uplink QoS information includes a QoS parameter obtained based on the traffic downlink QoS parameter, to request the access network device to configure a radio resource based on traffic reflective characteristic information.
[0013] In addition, the terminal can determine, based on a sequence of receiving the first pre-authorized QoS information and the traffic reflective characteristic information, which QoS information is used to request a radio resource. Specifically, the terminal can send the QoS request information using uplink QoS information corresponding to the information that is obtained later. Specifically, if the terminal receives the first pre-authorized QoS information first and then
Petition 870190068488, of 7/19/2019, p. 11/157
6/138 receives the reflective characteristic information, the uplink QoS information includes the QoS parameter obtained based on the traffic downlink QoS parameter, or if the terminal first receives the reflective characteristic information and then receives the first pre-authorized QoS information, the uplink QoS information includes at least part of the first pre-authorized QoS information.
[0014] Optionally, the QoS request information may further include traffic PDU session information, so that the access network device subsequently forwards to a core network user plan device based on the information of traffic PDU session, the data sent by the terminal.
[0015] In some embodiments, the reflective characteristic information includes a traffic downlink QoS parameter and indication information that is used to indicate an ability to obtain an uplink QoS parameter based on the link QoS parameter descending traffic. In addition, for some downlink traffic, during the establishment of traffic, the access network device not only sets up a downlink radio resource for the terminal, but also sets up an uplink radio resource for the terminal. In this case, the reflective characteristic information may also include configuration information for an uplink radio carrier. If the terminal subsequently sends the traffic data by using the QoS parameter obtained based on the traffic downlink QoS parameter, the terminal can send
Petition 870190068488, of 7/19/2019, p. 12/157
7/138 traffic data directly on a configured radio carrier.
[0016] In a real application, the terminal can send the QoS request information by using control plan signaling.
[0017] With reference to the third possible implementation, in a fourth possible implementation, the method may also include: receiving, through the terminal, updated reflective characteristic information sent by the access network device, where the updated reflective characteristic information is carried in a data packet header or is sent for using RRC radio resource control signaling.
[0018] With reference to the first to the fourth possible implementations, in a fifth possible implementation, the method also includes: receiving, through the terminal, the first updated pre-authorized QoS information sent by the core network control plan device, and updating the first locally authorized pre-authorized QoS information based on the first updated pre-authorized QoS information. The first updated pre-authorized QoS information can be sent by the core network control plan device in an area update procedure, or the first updated pre-authorized QoS information can be sent by the core control plan device. core network in a process in which the terminal is transferred between different access network devices.
[0019] In a sixth possible implementation, the sending, by the terminal, of traffic data based on the first information
Petition 870190068488, of 7/19/2019, p. 13/157
8/138 QoS for using a radio resource that is configured by an access network device for traffic can include the following two ways.
[0020] A first way: filter, through the terminal, the traffic data by using a packet filter indicated by the first QoS information; and send, through the terminal, a selected data packet to the access network device by using a radio carrier corresponding to the packet filter indicated by the first QoS information.
[0021] A second way:
determine a carrier radio corresponding to traffic; and send the data of traffic for the network device in unused access the radio carrier determined.[0022] Furthermore, if the terminal send the data of
traffic based on the first pre-authorized QoS information, in an implementation, the first pre-authorized QoS information can include a packet filter of at least one group of data packets and an identifier of a QoS parameter corresponding to at least one data packet group. In another implementation, the first pre-authorized QoS information may include traffic application layer information and a traffic QoS parameter identifier, and a correspondence between a QoS parameter identifier and traffic application layer information. The traffic layer information can be an application program ID, so the terminal can group data based on the application layer information.

[0026] In a first possible implementation of the second aspect, the configuration, by the first access network device, of a radio resource for a terminal based on the second QoS information includes: establishing, by the first access network device, a radio bearer and a correspondence between a group of data packets and the radio bearer based on the second QoS information, or establish a correspondence between a data packet group and a radio bearer based on the second QoS information .
[0027] In a second possible implementation of the second aspect, the method may also include: receiving, through the first access network device, second updated pre-authorized QoS information sent by the core network control plan device; and updating, via the first access network device, second pre-authorized QoS information stored locally using the updated pre-authorized QoS information.
[0028] Specifically, the second QoS information includes at least one of the second pre-authorized QoS information and reflective characteristic information, and the reflective characteristic information includes a traffic downlink QoS parameter and traffic information.

[0029] In a third possible implementation of the second aspect, the second pre-authorized QoS information can include at least one of the first indication information and the second indication information, where the first indication information is used to indicate whether it preconfigures a radio resource for a corresponding data packet group, the second indication information is used to indicate whether to pre-establish a terrestrial side channel for a corresponding data packet group, and the terrestrial side channel is a data channel between an access network device and a core network user plan device.
[0030] Correspondingly, the configuration, by the first access network device, of a radio resource for the terminal based on the second pre-authorized QoS information includes: when the first indication information indicates that a radio resource needs to be pre-configured for the corresponding data packet group, immediately configure, by the first access network device, a radio resource for the corresponding data packet group based on the second pre-authorized QoS information when receiving the second QoS information pre-authorized.

[0031] In a fourth possible implementation of the second

12/138 aspect, the configuration, by the first access network device, of a radio resource to the terminal based on the second pre-authorized QoS information includes: receiving, by the first access network device, request information from QoS sent by the terminal; and configure, by the first access network device, a radio resource for the terminal based on the QoS request information (corresponding to the second possible implementation of the first aspect).
[0032] In addition, the configuration, by the first access network device, of a radio resource for the terminal based on the QoS request information includes:
perform, by the first access network device,
verification at information from í request QoS; andto set up a resource in radio to < the terminal if the verification at information in solicitation of QoS for good- successful. [0033] A verification is held in information in solicitation in QoS, and a radio resource is configured for
the terminal after verification is successful, so that the security and appropriateness of resource allocation can be ensured.
[0034] In a fifth possible implementation of the second aspect, the method also includes:

[0035] Consult the communication method in the first aspect for the specific content of the information of
Petition 870190068488, of 7/19/2019, p. 18/157
13/138 QoS request and reflective characteristic information, and the detailed description is omitted in this document.
[0036] In a sixth possible implementation of the second aspect, the second pre-authorized QoS information may also include validation interval information, in which the validation interval information is used to indicate a geographical area in which the second Pre-authorized QoS is effective.
[0037] In a seventh possible implementation of the second aspect, the method also includes:
send, by the first network device accessing the core network user plan device through a corresponding terrestrial side channel, a data packet sent by the terminal.
[0038] The terrestrial channel is established so that each PDU session corresponds exclusively to a terrestrial channel.
[0039] In an eighth possible implementation of the second aspect, the receipt, by the first access network device, of the second pre-authorized QoS information includes: receiving, by the first access network device, a transfer request message ( handover) sent by a second access network device, where the transfer request message includes the second pre-authorized QoS information.
[0040] With reference to the eighth possible implementation, in a ninth possible implementation, the transfer request message carries at least a third indication information and data transmission indication information, where the third indication information
Petition 870190068488, of 7/19/2019, p. 19/157
14/138 is used to indicate whether a radio carrier has been established for a group of data packets on the source side, and data transmission indication information is used to indicate whether data in the data packet group has been transmitted or are being broadcast.
[0041] Correspondingly, the configuration, by the first access network device, of a radio resource for the terminal based on the second pre-authorized QoS information includes: determining, by the first access network device based on at least one of the following information, a radio resource for the terminal is configured: if the second access network device has established a radio carrier for the data packet group, if the data in the data packet group for which the second access network device established a radio carrier has been transmitted, and if the data from the data packet group to which the second access network device established a radio carrier is being transmitted.
[0042] After the first access network device sets up a radio resource for the terminal based on the second pre-authorized QoS information in the transfer request message, the method also includes:
sending a transfer response message to the second access network device by the first access network device, where the transfer response message includes a transfer preparation success message and a transfer preparation failure message, the transfer preparation success message is used to indicate that the first
Petition 870190068488, of 7/19/2019, p. 20/157
15/138 access network device determines to admit all or some resources requested by the transfer request message, and the transfer preparation failure message is used to indicate that the first access network device determines not to admit a resource requested by the transfer transfer request message.
[0043] In addition, the transfer preparation success message and the transfer preparation failure message carry a cause of transfer failure, where the cause of transfer failure is one of the following: there is no radio resource available, pre-establishing a radio carrier with pre-authorized QoS is not supported, a QoS parameter is not supported, and a geographic area is not supported.
[0044] According to a third aspect, an embodiment of the present invention further provides a method for communication, the method includes:
configure, by a core network control plan device, first QoS information and second QoS information for a terminal traffic, where the first QoS information and the second QoS information are configured before the terminal starts the traffic; and sending, via the core network control plan device, the first QoS information to the terminal, and sending the second QoS information to an access network device.
[0045] In a possible implementation of the third aspect, the method also includes:
update, by the network control plan device
Petition 870190068488, of 7/19/2019, p. 21/157
16/138 core, at least one of the first QoS information and the second QoS information in an area update procedure or in a process in which the terminal is transferred between different access network devices; and sending the first updated QoS information to the terminal, and sending the second updated QoS information to the access network device.
[0046] In the first aspect, the second aspect, and the third aspect, the first pre-authorized QoS information and the second pre-authorized QoS information are configured by the core network control plan device for the terminal, and can be stored in a terminal context and be sent to the terminal and the access network device. In a current application, the first pre-authorized QoS information can be sent directly to the terminal using a non-access layer message, or it can be sent to the terminal by the access network device for using an access layer message. . The second pre-authorized QoS information can be sent to the access network device by using an access layer message.
[0047] Before the terminal starts traffic, for example, sending a traffic request, the pre-authorized QoS information (including the first pre-authorized QoS information and the second pre-authorized QoS information) is allocated to the terminal, and the Pre-authorized QoS information is sent to the terminal and the access network device. Therefore, when the terminal initiates traffic, the access network device can configure a radio resource for the terminal without waiting for QoS information.
Petition 870190068488, of 7/19/2019, p. 22/157
17/138 authorized from a core network device, and the terminal can send traffic data by using the configured radio resource, so that a time for the terminal's traffic to start can be shortened.
[0048] During implementation, preferably in an existing signaling procedure, for example, in a PDU session process or an initial UE context configuration process, the first pre-authorized QoS information is sent to the terminal, and the second Pre-authorized QoS information is sent to the access network device, so that the signaling required for allocating QoS parameters can be reduced, and signaling overheads on one network side are reduced.
[0049] Optionally, the content of the first pre-authorized QoS information and the second pre-authorized QoS information can be the same or different. When the first pre-authorized QoS information is different from the second pre-authorized QoS information, the first pre-authorized QoS information can be a part of the second pre-authorized QoS information, or the first pre-authorized QoS information and the second pre-authorized QoS information partially overlap.
[0050] In addition, each of the first pre-authorized QoS information and the second pre-authorized QoS information can include one or more sets of QoS information, and each set of QoS information corresponds to a group of packets of data. In the following specification, each of the content included in the first pre-authorized QoS information and content included in the second pre-authorized QoS information is the content included in each set of
Petition 870190068488, of 7/19/2019, p. 23/157
18/138 QoS information. The first pre-authorized QoS information includes a plurality of sets of QoS information, and the second pre-authorized QoS information includes a plurality of sets of QoS information, so that the corresponding QoS information a plurality of groups of data packets can be sent to the terminal and the access network device at once. Network signaling overheads can be reduced compared to the prior art where a terminal requests to establish a dedicated carrier, and a QoS parameter is configured for one group of data packets at a time based on a request from the terminal, and is sent to the terminal and the access network device.
[0051] In the first aspect, the second aspect, and the third aspect, the core network control plane device notifies the access network device of the reflective characteristic information during the establishment of a downlink traffic. Specifically, the core network control plan device notifies the access network device of a downlink QoS parameter of the traffic, and indicates that the traffic has a reflective characteristic, that is, an uplink QoS parameter. of traffic can be obtained based on the downlink QoS parameter of the traffic. The access network device then sends the traffic reflective characteristic information to the terminal.
[0052] In addition, the access network device can notify the terminal of the traffic reflective characteristic information in one of the following two ways:
Petition 870190068488, of 7/19/2019, p. 24/157
19/138 [0053] In a first way, the terminal is notified in a user plan manner. For example, reflective characteristic information is carried in a PDCP layer data packet header. Alternatively, reflective characteristic information can be carried in a header from another protocol layer, for example, carried in a header from an RLC layer or a MAC layer.
[0054] In a second way, the terminal is notified in a control plan manner. For example, reflective characteristic information is sent to the terminal using an RRC message, and the message explicitly indicates that the traffic has a reflective characteristic (that is, an uplink traffic QoS parameter can be obtained based on a traffic downlink QoS parameter). Alternatively, an implicit way can be used, and a radio carrier uplink configuration is used to indicate that the traffic has a reflective characteristic. To be specific, if the access network device carries the uplink configuration of the radio carrier in the reflective characteristic information, it indicates that the traffic has a reflective characteristic.
[0055] Optionally, with reference to the first aspect, the second aspect and the third aspect, in some modalities, to save a communication resource, when the traffic is finished, both the access network device and the terminal need to release a configuration related resource.
[0056] In an optional implementation, the terminal can
Petition 870190068488, of 7/19/2019, p. 25/157
20/138 detect whether traffic is terminated. Correspondingly, the method also includes: detecting, by the terminal, if the traffic is finished; and when the terminal detects that traffic is terminated, send a service termination request to the access network device. Correspondingly, upon receiving the service termination request sent by the terminal, the first access network device releases, according to a service release request from the terminal, the radio resource allocated to traffic, and instructs the terminal to release a radio traffic resource configuration.
[0057] The terminal can detect traffic termination with the following way:
when a traffic data volume is zero or less than a specified threshold, start a timer from the terminal, and if the traffic data volume is not increased when the timer expires, detect that the traffic is terminated; or if the traffic data volume is increased before the timer expires, reset the timer, and restart the timer the next time the traffic data volume is zero or less than the specified threshold.
[0058] Alternatively, the terminal can also detect whether an end-of-traffic instruction for an application layer is received, and when the end-of-traffic instruction is received, it indicates that the traffic is terminated.
[0059] Optionally, the timer is defined by the core network control plan device, the timer is carried on the first pre-authorized QoS information and is sent to the terminal (for example, it is
Petition 870190068488, of 7/19/2019, p. 26/157
21/138 sent to the terminal using a NAS message); or the timer is set by the access network device and the timer is sent to the terminal using an RRC radio resource control message or a user plan control PDU protocol data unit.
[0060] Optionally, the terminal can send the traffic termination request to the access network device in a control plan or user plan manner. The control plan way can be a way of using an RRC message, where the RRC message includes QoS information from a group of data packets that needs to be finalized and indication information to request traffic termination, and information from QoS is a QoS parameter identifier. The user plan way can be a way of using a data packet that indicates that traffic ends. For example, a PDCP PDU is generated in a PDCP layer and the PDCP PDU is defined as a final marker PDU, to indicate that traffic ends. Alternatively, the PDCP PDU carries a QoS parameter identifier and traffic termination indication information, or a PDU format is used to indicate that the traffic is terminated. In addition, the access network device can still be notified using either an RLC PDU or a MAC PDU, and a way of using the RLC PDU and MAC PDU is similar to that of the PDCP PDU, and details are not described here again.
[0061] In another optional implementation, the access network device can detect whether traffic is terminated. Correspondingly, the method provided in the second aspect also includes: detecting, by the access network device,
Petition 870190068488, of 7/19/2019, p. 27/157
22/138 if traffic is terminated; and when the access network device detects that traffic is terminated, release the radio resource allocated to the traffic, and instruct the terminal to release a radio resource configuration from the traffic.
[0062] According to a fourth aspect, an embodiment of the present invention provides a method for communication, where the method includes: sending, by means of an access network device to a core network control plan device, a packet of data, for which no QoS parameters have been configured, which is a traffic and is sent by a terminal;
receive, by the access network device, QoS information sent by the core network control plan device, where the QoS information is generated based on the data packet, of the traffic, for which no QoS parameters have been configured ; and configure, by the access network device, a radio resource for traffic based on the QoS information.
[0063] In a possible implementation of the fourth aspect, the sending, by an access network device to a core network control plan device, of a data packet for which no QoS parameters have been configured, which is traffic that is sent by a terminal includes:
receive, by the access network device, an AS access layer message sent by the terminal, where the AS message includes a NAS PDU access layer protocol data unit, and the data packet for which no parameters QoS was configured on the NAS PDU; and
Petition 870190068488, of 7/19/2019, p. 28/157
23/138 route, through the access network device, the NAS PDU to the core network control plan device.
[0064] In a second possible implementation of the fourth aspect, the sending, by an access network device to a core network control plan device, of a data packet, for which no QoS parameters have been configured, which is a traffic and that is sent by a terminal includes:
receive, by the access network device, the data packet, for which no QoS parameters have been configured, which is the traffic and which is sent by the terminal using any of a signaling radio carrier, a common radio carrier and a standard radio carrier, where the common radio carrier is configured exclusively to send the data packet for which no QoS parameters have been configured, and the traffic data packet for which no QoS parameters have been configured carries new data indication information; and send, by the access network device to the core network control plan device, the received data packet, from traffic, for which no QoS parameters have been configured, where the data packet, for which none The QoS parameter that has been configured is sent to a core network user plan device through a terrestrial side channel and then is sent to the core network control plan device by the core network user plan device.
[0065] According to a fifth aspect, an embodiment of the present invention further provides a method for
Petition 870190068488, of 7/19/2019, p. 29/157
24/138 communication, in which the method includes:
send, through a terminal to a core network control plan device, a data packet, of a traffic, for which no QoS parameters have been configured;

[00137] In addition, memory 43 is a computer-readable storage medium and can be implemented by any type of volatile or non-volatile storage device or a combination thereof, such as a static random access memory (SRAM), an electrically erasable programmable read-only memory (EEPROM), an erasable programmable read-only memory (EPROM), a programmable read-only memory (PROM), a read-only memory (ROM), a magnetic memory, a flash memory, a magnetic disk or optical disk.
[00138] Referring to Figure 5, Figure 5 shows a method for communication according to an embodiment of the present invention. The method can be implemented using the system shown in Figure 1. The mode shown in Figure 5 is described using an example in which a radio resource is configured based on pre-authorized QoS information. The method includes the following steps.
[00139] S501. A core network control plan device sends the first pre-authorized QoS information to a terminal, and sends second pre-authorized QoS information to a first access network device.
[00140] The core network control plan device can configure the pre-authorized QoS information (including the first pre-authorized QoS information and the
Petition 870190068488, of 7/19/2019, p. 53/157
48/138 second pre-authorized QoS information) for the terminal based on subscription information (for example, terminal subscription information obtained from a home subscriber server (English: Home Subscriber Server, HSS for short) In addition, the core network control plan device can further configure the pre-authorized QoS information for the terminal based on common traffic (such as e-mail or Taobao) .The two cases can be combined.
[00141] In an implementation, the core network control plan device sends the second pre-authorized QoS information to the first access network device for using an access layer message (English: Access Stratum, AS for abbreviate) and the first access network device sends the first pre-authorized QoS information to the terminal using an AS message. In another implementation, the core network control plan device sends the second authorized QoS information to the first access network device for using an AS message and the core network control plan device sends the first information of authorized QoS for the terminal using a non-access layer message (English: Non-Access Stratum, NAS for short), as shown in Figure 5.
[00142] During implementation, the first pre-authorized QoS information and the second pre-authorized QoS information can be sent in a protocol data unit session establishment process (English: Protocol Data Unit, PDU for short), for example, can be sent by in a reply message from
Petition 870190068488, of 7/19/2019, p. 54/157
49/138 session establishment. Therefore, the core network control plan device can configure the pre-authorized QoS information for the terminal upon receiving a session establishment request message. It should be noted that, the PDU session establishment process can also be referred to as a public data network connection process (English: Public Data Network, PDN for short). Alternatively, the first pre-authorized QoS information and the second pre-authorized QoS information can also be sent in an initial UE context configuration process.
[00143] In addition, the content of the first pre-authorized QoS information and the second pre-authorized QoS information can be the same or different. When the first pre-authorized QoS information is different from the second pre-authorized QoS information, the first pre-authorized QoS information can be a part of the second pre-authorized QoS information, or the first pre-authorized QoS information and the second pre-authorized QoS information partially overlap.
[00144] Specifically, the first pre-authorized QoS information includes at least one QoS parameter identifier, and each QoS parameter identifier can be used as an index and correspond to a QoS parameter of a group of packets. data (ie an index of the QoS parameter corresponding to the data packet group). During implementation, in one way, a correspondence between a QoS parameter identifier and a QoS parameter is defined in a pattern. To be specific, a plurality of sets of
Petition 870190068488, of 7/19/2019, p. 55/157
50/138
QoS (for example, each set of QoS parameters can include a priority, latency and packet loss rate) is defined in the standard, a serial number is assigned to each set of QoS parameters, and the serial number can be used as the QoS parameter identifier. For example, a QoS parameter identifier 1 corresponds to a first set of QoS parameters in the standard. In another way, the correspondence between a QoS parameter identifier and a QoS parameter is configured by the core network control plan device, the QoS parameter identifier is used as an index and corresponds to a set of various parameters QoS parameters (for example, a QoS parameter identifier 2 corresponds to a set of parameters, such as priority, latency, packet loss rate, and guaranteed bit rate are configured on a core network. Both matches can be used individually or can coexist.
[00145] Optionally, the first pre-authorized QoS information may also include: network slice identification information (English: slice) of a data packet group, where the slice identification information includes at least one of the following: one Slice ID, a slice type, a tenant type, a tenant identifier, a network role identifier, and the like.
[00146] In a first implementation, the first pre-authorized QoS information also includes a packet filter, and each packet filter corresponds to a QoS parameter identifier. The packet filter can be configured to filter a packet of data based on 5-tuple IP information or based on an address of
Petition 870190068488, of 7/19/2019, p. 56/157
51/138 source and destination address, to obtain a group of data packets. The 5-tuple IP information is for an IP data packet, and can include one or more of a source IP address, a destination IP address, a source port, a destination port and a protocol number. The source address and the destination address are for a non-IP data packet (such as an Ethernet frame (English: Ethernet)). For example, a group of IP data packets can be obtained by filtering using a 5-packet IP packet filter. For another example, a group of Ethernet frames can be obtained by filtering using a packet filter of at least one from a source address and a destination address from an Ethernet frame.
[00147] In a second implementation, the first pre-authorized QoS information also includes a correspondence between a QoS parameter identifier and application layer information. The application layer information can be information such as an application program ID for an application layer, so that the terminal can group a data packet using the application layer information, and match the data packet to a QoS parameter identifier.
[00148] In addition, the first pre-authorized QoS information may include one or more sets of QoS information, where each set of QoS information includes a QoS parameter identifier from a group of data packets and other corresponding information (such as traffic application layer information or a packet filter or a QoS parameter). The first pre-authorized QoS information includes a plurality of information sets
Petition 870190068488, of 7/19/2019, p. 57/157
52/138 of QoS, so that the QoS information corresponding to a plurality of groups of data packets can be sent to the terminal at once. Network signaling overheads can be reduced compared to the prior art where a terminal requests to establish a dedicated carrier, and a QoS parameter is configured for one group of data packets at a time based on a request from the terminal, and is sent to the terminal.
[00149] The second pre-authorized QoS information may include the content of the first pre-authorized QoS information; or include a portion of the content of the first pre-authorized QoS information. For example, the first pre-authorized QoS information includes a QoS parameter identifier and a corresponding packet filter (that is, the first implementation of the first pre-authorized QoS information) and the second pre-authorized QoS information includes only a QoS parameter identifier, but not a packet filter.
[00150] It should be noted that, when the correspondence between a QoS parameter identifier and a QoS parameter is defined by the standard, the correspondence can be pre-configured by an access network device; therefore, the second pre-authorized QoS information may include a QoS parameter corresponding to a group of data packets, or it may not include a QoS parameter corresponding to a group of data packets. When the correspondence between a QoS parameter identifier and a QoS parameter is configured by the core network control plan device for the terminal, the second pre-authorized QoS information must include the QoS parameter
Petition 870190068488, of 7/19/2019, p. 58/157
53/138 corresponding to the QoS parameter identifier.
[00151] Specifically, the QoS parameter can include one or more priorities, a packet loss rate, a latency, a guaranteed bit rate (English: Guaranteed Bit Rate, GBR for short), a maximum rate, a requested rate , a single data packet drop precedence, a single data packet priority, a session fee, and an allocation and retention priority (English: Allocation and Retention Priority, ARP for short). The guaranteed bit rate is a rate that the data packet group needs a network to guarantee. The maximum rate is a maximum transmission rate for the data packet group. The requested rate is a rate that a non-GBR (English: non) traffic requests the network to offer, and is usually a rate required by the data packet group to service the traffic. The session fee is a maximum of a sum of fees provided for all groups of non-guaranteed bit rate data packets in a PDU session. The allocation and retention priority indicates a level of anticipation and being
anticipated of a group of data packages. [00152] In addition, during implementation, for one traffic from guaranteed bit rate, the parameter in QoS usually includes at least one priority, one rate in
packet loss, latency and guaranteed bit rate. For non-guaranteed bit rate traffic, the QoS parameter generally includes at least one priority, packet loss rate and latency.
[00153] Optionally, the second pre-authorized QoS information may also include aggregated QoS information, where the aggregated QoS information is used to indicate
Petition 870190068488, of 7/19/2019, p. 59/157
54/138 a general QoS requirement for a plurality of data packet groups. For example, the second pre-authorized QoS information may further include a maximum aggregate rate for a plurality of data packet groups, where the maximum aggregate rate indicates a maximum transmission rate for the plurality of data packet groups. During implementation, the plurality of groups of data packets may belong to the same traffic and, in addition, the traffic may be non-guaranteed bit rate traffic. Alternatively, the plurality of data packet groups can belong to the same network slice (English: slice). In addition, a maximum aggregate rate of the plurality of data packet groups can be a maximum aggregate rate of data packet groups of all non-GBR traffic of the slice, for example, an aggregate maximum bit rate of the network slice ( English: slice-Aggregate Maximum Bit Rate, sliceAMBR for short). The network slice is a combination of a logical network function that supports a communication service requirement in a specific case. The network slice uses a logical resource instead of a physical resource, and helps the operator to provide a service-based network architecture.
[00154] In a subsequent data packet transmission process of the data packet group, the first access network device performs rate control based on the aggregated QoS information, so that a maximum global rate of the data group data packets does not exceed a maximum aggregate rate of aggregated QoS information. For example, rate control is performed using uplink scheduling processing or
Petition 870190068488, of 7/19/2019, p. 60/157
55/138 downlink.
[00155] In addition, optionally, the second pre-authorized QoS information may also include the first indication information, where the first indication information is used to indicate whether the first access network device pre-configures a radio resource for a group of corresponding data packets after receiving the second pre-authorized QoS information. Pre-configuring a radio resource is immediately configuring a radio resource after receiving pre-authorized QoS information.
[00156] In an implementation, the first indication information can be configured separately based on each group of data packets, for example, indicates that a radio resource needs to be pre-configured for a group of data packets 1 and a radio resource does not need to be pre-configured for a data packet group 2. Alternatively, the first indication information can be configured based on a QoS parameter of a data packet group. Specifically, the first indication information can be defined based on a QoS parameter, such as a category, priority or latency. For example, if a radio resource needs to be pre-configured, it is defined separately based on GBR traffic and non-GBR traffic (category). Alternatively, the first indication information indicates that a radio resource needs to be preconfigured for a group of data packages with a high priority (priority), or indicates that a radio resource needs to be preconfigured for a group of data packages. data that has a strict requirement on a data latency (for example, a latency value is less
Petition 870190068488, of 7/19/2019, p. 61/157
56/138 than a specified value) (latency).
[00157] In addition, for a group of data packets for which a radio resource needs to be pre-established, the first indication information can also indicate a priority for a pre-established radio resource, and the access network device can selectively establish a radio resource for the data packet group depending on the network status. For example, when the network load is relatively high, a radio resource can be established only for a group of high priority data packets, and when the network load is relatively low, a radio resource can also be established for a group of low priority data packets.
[00158] Therefore, a radio resource can be flexibly established for a group of data packages with pre-authorized QoS. The priority of the pre-established radio resource can be defined based on one or more of the QoS parameters of the data packet group, for example, it can be defined based on one or more of QoS parameters, such as the category , priority, and latency.
[00159] During implementation, the first indication information may indicate only one group of data packets for which a radio resource needs to be pre-configured, and if there is no explicit indication of a group of data packets for which a radio resource needs to be pre-configured, the first access network device may not need to immediately establish a radio resource by default.
[00160] An effective interval of the first information of
Petition 870190068488, of 7/19/2019, p. 62/157
57/138 indication can be uplink traffic, downlink traffic or uplink and downlink traffic. For example, if the effective range of the first indication information is uplink traffic, an uplink radio resource is preconfigured for the data packet group, but a downlink radio resource is not preconfigured. configured.
[00161] In another implementation, one or more groups of data packages for which radio resources need to be preconfigured or one or more groups of data packages for which no resources need to be preconfigured can be determined through network negotiation or protocol agreement. In this case, the pre-authorized QoS information may not include the first indication information. In addition, it can be considered by default that a radio resource needs to be preconfigured for all pre-authorized QoS information, or it can be considered by default that there is no need for radio resources to be preconfigured for all QoS information pre-authorized.
[00162] Optionally, if it is necessary to establish a data channel for data between the first access network device and a core network user plan device, the pre-authorized QoS information may also include second indication information, wherein the second indication information is used to indicate whether to establish a data channel, namely, to establish a land-side channel between the first access network device and the core network user plan device. The data channel can be a carrier or a tunnel.
Petition 870190068488, of 7/19/2019, p. 63/157
58/138 [00163] Furthermore, if there is no need for a data channel to be established for the data between the first access network device and the core network user plan device or a data channel only needs to be established for each terminal or each PDU session, for example, a data channel has been established for the terminal or the terminal's PDU session between the first access network device and the core network user plan device, the second pre-authorized QoS information need not include the second referral information.
[00164] During implementation, the first indication information and the second indication information can be the same indication information. To be specific, the indication information simultaneously indicates whether to establish a radio carrier and a terrestrial carrier or a data channel.
[00165] In addition, the second pre-authorized QoS information may also include validation interval information, where the validation interval information is used to indicate a geographical area in which the second pre-authorized QoS information is effective, and the Geographic area can be represented using a list of location areas and / or a list of routing areas.
[00166] S502. The first access network device receives the second pre-authorized QoS information, and configures a radio resource based on the second pre-authorized QoS information.
[00167] In this modality, the configuration of a radio resource is to allocate a radio resource for the transmission of
Petition 870190068488, of 7/19/2019, p. 64/157
59/138 aerial interface of a data packet, to carry out uplink data transmission, and may include establishment of a radio carrier (English: Radio Bearer, RB for short) and a mapping relationship between a radio carrier and a data packet group (applicable to a case where a radio carrier needs to be established for a data packet group), or it can include just setting up a mapping relationship between a data packet group and a radio carrier (applicable for a case where a group of data packets has been mapped to an existing radio carrier). The radio carrier is used to transmit data from the air interface, and the terminal can send the group of data packets on a corresponding radio carrier based on the mapping relationship between a group of data packets and a radio carrier. In addition, the access network device can determine, according to a radio resource management policy (English: Radio Resource Management, RRM for short), to establish a new radio carrier for a corresponding group of data packets to the QoS parameter or map the data packet group to an existing radio carrier.
[00168] Establishing a radio carrier includes establishing or modifying a radio carrier on an air interface, where a protocol stack corresponding to the RB includes a Packet Data Convergence Protocol (English: Packet Data Convergence Protocol, PDCP for abbreviate), a Radio Link Control Protocol (English: Radio Link Control Protocol, RLC for short) and a logical channel parameter setting
Petition 870190068488, of 7/19/2019, p. 65/157
60/138 (English: Logical Channel, LCH for short). The first access network device configures a related parameter for each layer of the protocol stack, to indicate a transmission characteristic of the radio carrier (English: Radio Bearer, RB for short) and adapt to the QoS parameter.
[00169] In addition, in a process of configuring a radio resource, the first access network device may consider one or both slice identification information and session information from the data packet group. For example, the first access network device maps groups of data packets that belong to different slices to different radio bearers, or it can map groups of data packets that belong to different sessions to different radio bearers.
[00170] In addition, the access network device can configure a connection relationship between a group of data packets and a radio bearer, and the same bearer of
radio can be linked to bundle groups data from a
same PDU session.
[00171] The configuration information carrier
radio includes a PDCP parameter setting, a
RLC parameter setting and a configuration of
LCH parameter.
[00172] The PDCP parameter setting can include one or more discard timers (English: discardTimer), header suppression, a reordering timer, an SN length and the like.
[00173] The RLC parameter configuration can include one or more of an RLC uplink / link mode
Petition 870190068488, of 7/19/2019, p. 66/157
61/138 descending, a search retransmission timer, a status ban timer (English: tStatusProhibit), a search PDU, a search byte, a maximum amount of retransmissions, a reordering timer (English: t-Reordering ), a length of SN and the like.
[00174] The logical channel parameter setting for a MAC layer can include one or more priority (English: priority), a nominal rate (English: prioritized bit rate), a deposit size duration (English: bucket size duration ), a group of domestic logical channels (English: logical channel group) and the like.
[00175] The mapping relationship between a data packet group and a radio carrier can be any of the following relationships: a mapping relationship between a data packet group identifier and an RB (such as a mapping relationship between the previous QoS parameter identifier and an RB), a mapping relationship between a packet filter and an RB, a mapping relationship between a data packet group priority and an RB (different priority data groups are mapped for different RBs) or a mapping relationship between a traffic category corresponding to a group of data packets and an RB. The mapping relationship between a traffic category corresponding to a group of data packets and an RB includes, but is not limited to: mapping a group of GBR data packets and a group of non-GBR data packets to different RBs, or map all non-GBR data packet groups to a specified RB, or map non-GBR traffic packet groups from the same PDU session to
Petition 870190068488, of 7/19/2019, p. 67/157
62/138 the same RB (for example, the mapping relationship can be a mapping relationship between an APN of a group of non-GBR traffic data packets and a DRB ID, or a mapping relationship between an IP address of a non-GBR traffic data packet group and a DRB ID, or a mapping relationship between a tunnel ID of a non-GBR traffic data packet group and a DRB ID). Alternatively, the mapping relationship between a group of data packets and a radio carrier can additionally be a combination of at least two of the previous mapping relationships, for example, groups of data packets obtained by combining a packet filter and a priority are mapped to an RB.
[00176] In addition, in a process of configuring a radio resource, the first access network device may also consider one or both of the slice identification information and the session information of the data packet group. For example, the first access network device maps the groups of data packets that belong to different slices to different radio carriers, and can also map the groups of data packets that belong to different sessions to different radio carriers. Accordingly, correspondingly, the mapping relationship between a group of data packets and a radio carrier can further include a mapping relationship between a session and a radio carrier or a mapping relationship between a slice and a radio carrier.
[00177] It should be noted that if the first access network device maps the group of data packets to an existing radio carrier, in step S502, only the
Petition 870190068488, of 7/19/2019, p. 68/157
63/138 mapping relationship between a radio carrier and a group of data packets needs to be established, and no radio carrier needs to be established or modified.
[00178] For downlink traffic, the first access network device sets up a mapping relationship between a group of data packets and an RB.
[00179] Specifically, step S502 can include:
when the second pre-authorized QoS information includes the first indication information, and the first indication information indicates that a radio resource needs to be pre-configured for the corresponding data packet group, immediately configure a radio resource for the group of data data packets corresponding to a QoS parameter in the second pre-authorized QoS information; or when the second pre-authorized QoS information includes the first indication information, and the first indication information indicates that no radio resource needs to be pre-configured for the corresponding data packet group, or the second pre-authorized QoS information does not include the first indication information indicating that a radio resource needs to be pre-configured for the corresponding data packet group, configure a radio resource for the data packet group when the terminal initiates traffic (for example, sends a traffic request).
[00180] S503. The terminal receives the first pre-authorized QoS information.
[00181] After receiving the first pre-authorized QoS information, the terminal stores the first pre-authorized QoS information, so that when traffic is
Petition 870190068488, of 7/19/2019, p. 69/157
64/138 subsequently started, traffic data is sent based on the first pre-authorized QoS information. Therefore, step S503 is performed before the terminal initiates traffic, namely, it is performed before the terminal sends a traffic request.
[00182] Optionally, the core network control plan device can update pre-authorized QoS information using an area update procedure, such as location area update and / or routing area update, to update part or all pre-authorized QoS information (including at least one of the first pre-authorized QoS information and the second pre-authorized QoS information). The terminal and the first access network device receive updated pre-authorized QoS information, and update the locally authorized pre-authorized QoS information.
[00183] S504. The first access network device sends radio resource configuration information to the terminal.
[00184] The radio resource configuration information includes the radio carrier configuration information and the mapping relationship between a group of data packets and a radio carrier; or the radio resource configuration information includes the mapping relationship between a group of data packets and a radio carrier.
[00185] Optionally, the radio resource configuration information may also include configuration information of the way of transmitting data from a data packet. A way of transmitting data includes a way of scheduling a base station and a way of
Petition 870190068488, of 7/19/2019, p. 70/157
65/138 terminal competition. When the data transmission mode is the terminal competition mode, the radio resource configuration information also includes a competition resource configuration, such as a common competition channel configuration or a competition rule configuration. The common channel configuration can be a channel resource configuration, for example, one or both of a different protocol layer configuration corresponding to a common channel and configuration information for a time-frequency domain resource corresponding to the common channel . A competition rule may include one or more rules of running competition from the terminal, running the competition again after a random time after competition kickback and the like.
[00186] S505. The terminal receives the radio resource configuration information.
[00187] The terminal receives and stores the radio resource configuration information, so that the terminal subsequently sends traffic data by using a corresponding radio resource.
[00188] It should be noted that there is no sequence between step S503 and step S505.
[00189] S506. The first access network device establishes a data channel between the first access network device and a core network user plan device.
[00190] Specifically, the first access network device and the core network user plan device exchange data channel establishment information, to establish the data channel. During the
Petition 870190068488, of 7/19/2019, p. 71/157
66/138 implementation, the data channel between the first access network device and the core network user plan device can be established in a PDU session establishment process.
[00191] It should be noted that when the second pre-authorized QoS information includes the second indication information, and the second indication information indicates that a data channel needs to be pre-established for the data packet group, step S506 it must be executed immediately after the first access network device receives the second pre-authorized QoS information.
[00192] The data channel can be established so that each PDU session corresponds to a data channel, that is, each PDU session corresponds only to a data channel, or it can be established so that each terminal corresponds to a data channel, that is, each terminal corresponds exclusively to a data channel.
[00193] The first access network device stores a correspondence between an RB and a data channel, and the core network user plan device stores a mapping relationship between a data channel and a packet filter.
[00194] 507. When starting a traffic, the terminal sends traffic data based on the first pre-authorized QoS information.
[00195] Specifically, step S507 can include: when the terminal has traffic data to be sent, filter the traffic data by using a packet filter; and send a selected data packet to the device
Petition 870190068488, of 7/19/2019, p. 72/157
67/138 access network using a corresponding radio carrier based on the mapping relationship, the radio resource configuration information, between a group of data packets and a radio carrier.
[00196] In an implementation, the corresponding radio carrier can be directly determined based on the mapping relationship between a group of data packets and a radio carrier, for example, when the mapping relationship between a group of data packets and a radio bearer is a mapping relationship between data packet group identifier and a radio bearer.
[00197] In another implementation, the corresponding radio carrier needs to be indirectly determined based on the mapping relationship between a group of data packets and a radio carrier, for example, the radio resource configuration information carries a relationship of mapping between a QoS parameter and a radio carrier (for example, a mapping relationship between a data packet group priority and an RB, or a mapping relationship between a data packet latency and an RB ). In this case, sending a selected data packet to the access network device using a corresponding radio carrier based on matching, radio resource configuration information, between a group of data packets and a radio carrier includes:
determine, based on a packet filter passed through the selected data packet, a QoS parameter identifier corresponding to the packet filter; obtain a QoS parameter corresponding to the QoS parameter identifier;
Petition 870190068488, of 7/19/2019, p. 73/157
68/138 and determine, based on the QoS parameter obtained, a radio carrier corresponding to the group of data packets.
[00198] Alternatively, step S507 can include:
determine a radio carrier corresponding to the traffic; and sending traffic data to the first access network device for using the specified radio carrier. The radio bearer corresponding to the traffic is determined based on the correspondence, the radio resource configuration information, between a group of data packets and a radio bearer.
[00199] Optionally, when the radio resource configuration information also includes a way of transmitting data, sending the data packet to the first access network device may include:
when the way of transmitting data from the terminal is the way of scaling the base station, select, through the terminal based on the mapping relationship between a group of data packets and an RB, an RB corresponding to the group of data packets, and send the data packet for the first access network device in the RB; or when the terminal's way of transmitting data is the competition way, run, through the terminal, competition on a common channel, and send the data on a corresponding resource if the competition is successful.
[00200] During the implementation, the group of data packets that passes the packet filter can be called flow (English: flow). Therefore, the previous mapping relationship between a group of data packets and an RB can still be
Petition 870190068488, of 7/19/2019, p. 74/157
69/138 referred to as a mapping relationship between a stream and an RB.
[00201] S508. The first access network device receives the data sent by the terminal, and forwards the data to the core network user plan device.
[00202] Specifically, the access network device sends the received data packet to the core network user plan device through the data channel between the access network device and the network user plan device. core. The data channel between the access network device and the core network user plan device can be established in the PDU session establishment process.
[00203] Specifically, step S508 includes: sending, by the first access network device, the data packet to the core network user plan device through a corresponding data channel.
[00204] In addition, when the data channel is established in a way that each PDU session corresponds to a data channel, step S508 is implemented as follows:
obtain, from the access network device, PDU session information corresponding to the data packet; and sending the data packet to the core network user plan device using a data channel corresponding to the session information from the PDU.
[00205] Specifically, the obtaining, by the access network device, of PDU session information corresponding to the data package can be implemented as follows:
when the second pre-authorized QoS information is
Petition 870190068488, of 7/19/2019, p. 75/157
70/138 notified by the network control plan device to the access network device or QoS information authorized by the network control plan device to the access network device includes session information, PDU session information corresponding to the data package can be obtained from the second pre-authorized QoS information or from the authorized QoS information.
[00206] In addition, the second pre-authorized QoS information or the authorized QoS information may explicitly or implicitly include the PDU session information. For example, the second pre-authorized QoS information in the session establishment process may implicitly include the session information, and the session specific information is associated based on the different session establishment processes. When the core network control plan device notifies the access network device of the authorized QoS, the session information can be explicitly carried in the QoS information.
[00207] The access network device can filter the data packet, to obtain a QoS parameter corresponding to the data packet, and obtain session information based on the QoS parameter. Therefore, the data packet is mapped to the corresponding data channel, and a routing operation is implemented. In the session establishment process, a session data channel is established between the access network device and the core network user plan device, and is used for data transmission from the PDU session on an earth side .
Petition 870190068488, of 7/19/2019, p. 76/157
71/138 [00208] For example, a data packet group 1 belongs to a session 1 and a data packet group 2 belongs to a session 2. The access network device receives multiple uplink data packets, filters the data packets using a packet filter 1 from data packet group 1 to obtain a data packet from data packet group 1, and delivers the data packet from data packet group 1 to a data channel 1 corresponding to session 1, to implement the routing; filters the data packets using a packet filter 2 from data packet 2 to obtain a data packet from data packet group 2, and delivers the data packet from data packet group 2 to a corresponding data channel 2 to session 2, to implement routing. In addition, the access network device can combine packet filters from all data packet groups in session 1 to obtain a group of packet filters from session 1, and the access network device provides the data channel 1 corresponding to session 1, a data packet that is obtained by filtering using the packet filter group from session 1, to implement routing.
[00209] Furthermore, if the same radio carrier is connected only to groups of data packets from the same session, that is, if several groups of data packets from session 1 are mapped to the same radio carrier, the device Access network provider provides an uplink data packet from the radio carrier to data channel 1 corresponding to session 1, to implement routing without a packet filtering operation.
[00210] In addition, for link traffic
Petition 870190068488, of 7/19/2019, p. 77/157
72/138 descending, the first access network device configures the mapping relationship between a group of data packets and an RB. When sending downlink data, the first access network device selects an RB corresponding to the group of data packets using the mapping relationship between a group of data packets and an RB, and sends the data to the terminal using the RB selected.
[00211] In this mode, before the terminal starts traffic, the pre-authorized QoS information (including the first pre-authorized QoS information and the second pre-authorized QoS information) is allocated to the terminal, and the QoS information authorization is sent to the terminal and the access network device. Therefore, when the terminal initiates traffic, the access network device can configure a radio resource for the terminal without waiting for authorized QoS information from a core network device, and the terminal can send unused traffic data. the radio resource configured, so that a time to initiate traffic from the terminal can be shortened, and signaling overloads on one side of the core network can be reduced. In addition, if the access network device immediately sets up a radio resource for the terminal after obtaining the pre-authorized QoS information, the terminal can enter a linked state before sending the data packet. A radio carrier and / or a terrestrial data channel is / is established, and when the terminal needs to send uplink data, the terminal can directly send data on the pre-established radio carrier, thereby increasing the initial speed data transmission and improving the
Petition 870190068488, of 7/19/2019, p. 78/157
73/138 user experience.
[00212] Referring to Figure 6, Figure 6 shows a method for communication according to an embodiment of the present invention. The method is implemented using the system shown in Figure 1. In the embodiment shown in Figure 6, this embodiment of the present invention is described in detail using an example in which a radio resource is configured based on pre-authorized QoS information in a transfer process. The method includes the following steps.
[00213] S601. A second access network device sends a transfer request message to a first access network device.
[00214] The second access network device can also be referred to as a source-side access network device, and the first access network device can also be referred to as a target side access network device. A transfer process message between the first access network device and the second access network device can be sent and received through a direct interface between the first access network device and the second access network device (a transfer process between peer entities), or can be forwarded by third parties, for example, through a core network control plan device (a transfer process carried out through a core network).
[00215] The transfer request message includes pre-authorized QoS information. The QoS information pre-authorized in the transfer request message can
Petition 870190068488, of 7/19/2019, p. 79/157
74/138 include some or all of the second pre-authorized QoS information in the mode shown in Figure 5, for example, it can include only the QoS parameter identifier in step S501 and a QoS parameter corresponding to the QoS parameter identifier; or it can include the QoS parameter identifier, the QoS parameter corresponding to the QoS parameter identifier, and the packet filter corresponding to the QoS parameter; or it can also include the first indication information.
[00216] During implementation, the core network control plan device can update the pre-authorized QoS information using a transfer process, for example, update part or all of the pre-authorized QoS information using the transfer request message , and send updated pre-authorized QoS information to the target side access network device and / or a terminal. The terminal and the target side access network device receive the updated pre-authorized QoS information, and update locally stored pre-authorized QoS information. The terminal obtains the updated pre-authorized QoS information using an air interface message in the transfer process.
[00217] In addition, the transfer request message may also include third indication information, where the third indication information is used to indicate whether a radio carrier has been established for a group of data packets on the source side.
[00218] In an implementation, the third indication information can be an explicit indication for each group of data packages, for example, attribute information
Petition 870190068488, of 7/19/2019, p. 80/157
75/138 carrying a QoS parameter, where the attribute information is used to indicate whether a radio resource has been configured for a group of data packets, that is, whether a match between a group of data packets and a carrier of data radio was established on the source side. In this implementation, the transfer request message may further include data transmission indication information, where the data transmission indication information is used to indicate whether data from the data packet group for which a radio resource has been configured on the source side have been transmitted or are being transmitted.
[00219] In another implementation, the third indication information can be an implicit indication. For example, if the transfer request message carries a correspondence between a group of data packets and a radio carrier, it indicates that a radio resource has been configured on the source side for the data packet group corresponding to the set of data QoS parameters, or if the transfer request message does not carry the correspondence between a group of data packets and a radio carrier, this indicates that no radio resource has been configured on the source side for the corresponding data packet group to the set of QoS parameters. In this implementation, the transfer request message may also include data transmission indication information, where the data transmission indication information is used to indicate whether data from the data packet group for which a radio resource has been configured on the source side has been transmitted or is being transmitted.
[00220] In another implementation, the request message
Petition 870190068488, of 7/19/2019, p. 81/157
The transfer may not include the third indication information or the data transmission indication information, but another message in the transfer process is used to carry the third indication information and the data transmission indication information. For example, a message that is sent by the source side access network device to the target side access network device and that carries a serial number status report (English: Serial Number status report, SN status report for short) can only carry an SN status of a data packet group for which the mapping relationship between a data packet group and a radio carrier has been established, where the SN status is a link SN PDCP ascending / descending link (English: uplink / downlink) and hyper frame number status (English: Hyper Frame Number, HFN for short). A target side receives the message that carries the SN status report, and can set a specific group of data packets for which a radio carrier has been established. If a PDCP SN and an HFN from the data packet group are both 0, this indicates that no data is being transmitted. In other words, PDCP SN and HFN are used as third implicit indication information and data transmission indication information.
[00221] S602. The first access network device receives the transfer request message, and determines, based on the pre-authorized QoS information in the transfer request message, to make a judgment on request admission, to determine whether to admit a transfer appeal. radio requested in the message
Petition 870190068488, of 7/19/2019, p. 82/157
77/138 transfer request.
[00222] To admit the radio resource requested in the transfer request message is to configure the radio resource for the terminal based on the radio resource requested in the transfer request message. See step 502 for specific implementation of the radio resource configuration, and the detailed description is omitted in this document.
[00223] Specifically, the first access network device can use one or more pieces of the following information as an input to an admission judgment algorithm, to perform judgment on admission request:
a QoS parameter corresponding to each data packet group in the pre-authorized QoS information, if a radio resource has been configured for a data packet group corresponding to the QoS parameter, if the data in the corresponding data packet group to the QoS parameter were sent, and whether data from the data packet group corresponding to the QoS parameter is being transmitted.
[00224] For example, when performing the admission judgment, the first access network device can consider only the group of data packets for which a radio resource has been configured, and determine based on the group's QoS parameter data packets and a resource status of the target side, the group of data packets for which a radio carrier has been established in the side source is admitted. For another example, when the target side is lacking network resources, only a resource request from a group of data packets with data to be sent can be considered.
[00225] S603. The first access network device
Petition 870190068488, of 7/19/2019, p. 83/157
78/138 sends a transfer response message to the second access network device, where the transfer response message can be a transfer preparation failure message or a transfer preparation success message.
[00226] Specifically, when determining that none of the resources requested in the transfer request message is admitted, the first access network device sends the transfer preparation failure message, in which the transfer preparation failure message is used to indicate that none of the resources requested in the transfer request message are supported; or when determining that all or some resources requested in the transfer request message are admitted, the first access network device sends a transfer preparation success message. That some of the features requested in the transfer request message are not supported may include that some groups of data packets in the pre-authorized QoS information for which the radio carriers need to be pre-established are not supported by the first network device access.
[00227] In addition, the transfer preparation failure message may still carry a cause of transfer failure. One cause of failure can be provided for each group of data packets in the transfer request. The cause of failure includes, but is not limited to: there is no radio resource available, pre-establishment of a radio carrier with pre-authorized QoS is not supported, a QoS parameter is not supported, an area
Petition 870190068488, of 7/19/2019, p. 84/157
79/138 geographic is not supported and the like. That a geographic area is not supported is that traffic is not supported in a target cell of the target access network device, for example, some traffic is effective only in a given geographic area. That a QoS parameter is not supported is that traffic corresponding to the QoS parameter cannot be supported on the destination access network device.
[00228] In addition, the transfer preparation success message may still carry a cause of transfer failure. In addition, a cause of failure can be provided for each group of data packages for which a resource is unsuccessfully prepared. For example, a list is carried forward, where the list includes an identifier for a group of data packets for which a resource is unsuccessfully prepared and a corresponding cause of failure. The cause of failure includes, but is not limited to: there is no radio resource available, pre-establishing a radio carrier with pre-authorized QoS is not supported, a QoS parameter is not supported, a geographic area is not supported and the like. That a geographic area is not supported is that traffic is not supported in a target cell of the target access network device, for example, some traffic is effective only in a given geographic area. That a QoS parameter is not supported is that traffic corresponding to the QoS parameter cannot be supported on the destination access network device.
[00229] In addition, the transfer preparation success message also includes related resource configuration information from a group of data packets for the
Petition 870190068488, of 7/19/2019, p. 85/157
80/138 which a resource is successfully prepared.
[00230] S604. The second access network device receives the transfer response message and determines, based on the transfer response message, whether to initiate the transfer execution.
[00231] Specifically, if the second access network device receives the transfer preparation success message, the second access network device can start the transfer execution, and transfer the terminal to a destination cell, where the cell destination is a cell provided by the first access network device.
[00232] In addition, the second access network device may determine, based on the status of an admitted resource that is requested by the source side, not to initiate the transfer execution. For example, the target side admits only resource requests for some traffic, and the ladofonte determines not to initiate the transfer execution. Alternatively, the source side may determine, based on a type of traffic received by the target side, such as an authorized service or a pre-authorized service, whether to initiate a transfer.
[00233] S605. When the second access network device determines to initiate the transfer execution, the second access network device sends the radio resource configuration information to the terminal that is sent by the first access network device and is from a packet group. of data for which a resource is successfully prepared.
[00234] See step S504 for specific content of radio resource configuration information
Petition 870190068488, of 7/19/2019, p. 86/157
81/138 and the detailed description is omitted in this document.
[00235] S606. The terminal receives the radio resource configuration information.
[00236] In step S606, the terminal receives and stores the radio resource configuration information.
[00237] S607. When starting a traffic, the terminal sends traffic data to the first access network device based on the first pre-authorized QoS information
using a resource in radio configured for the first device network in access. [00238] Read more O step S507 for a process of
specific implementation of step S607, and the detailed description is omitted in this document.
[00239] S608. The first access network device receives the data sent by the terminal and sends the data to a core network user plan device.
[00240] See step S508 for a process of implementing step S608, and the detailed description is omitted in this document.
[00241] This modality is described using an example in which the terminal is transferred between access network devices in a radio access network. When the terminal is transferred between radio access networks, a transfer request message sent by the source side access network device can carry only QoS information to require the target side access network device to establish a radio resource. After receiving the transfer request message, the target side executes the admission decision on the QoS information included in the transfer request message, and if
Petition 870190068488, of 7/19/2019, p. 87/157
82/138 the target side is successful or partially successful on admission, the target side returns a transfer preparation success message or otherwise, it returns a transfer preparation failure message.
[00242] In this mode, the source-side access network device can determine, based on the transfer preparation success message from the target-side access network device, whether to initiate a transfer, and transfer the terminal to the target side access network device, so that the mobility performance of the terminal can be ensured. The target side access network device configures a radio resource for the terminal in the pre-authorized QoS-based transfer process. After the terminal is transferred to the target side access network device, and when the data from the terminal arrives, the terminal can directly send data on the configured radio resource, thereby increasing the initial data transmission speed and improving the user experience.
[00243] Referring to Figure 7, Figure 7 shows another method for communication according to an embodiment of the present invention. The method is implemented using the system shown in Figure 1. In the mode shown in Figure 7, the method includes the following steps.
[00244] S701. A core network control plan device sends first pre-authorized QoS information to a terminal, and sends pre-authorized QoS information to an access network device.
[00245] See S501 for a specific implementation process, and the detailed description is omitted in this
Petition 870190068488, of 7/19/2019, p. 88/157
83/138 document.
[00246] S702. When initiating traffic, the terminal sends QoS request information to the access network device.
[00247] Specifically, the terminal can send the QoS request information to the access network device using control plan signaling, for example, using an SRB message; or the terminal can send the QoS request information to the access network device in a user plan manner.
[00248] When the terminal sends the QoS request information to the access network device in the form of a user plan, a form of a Media Access Control-Control Element (English: Media Access Control-Control Element, MAC-CE for short) can be used or an uplink data packet is sent on a standard carrier, and new data indication information is carried in a data packet header. The new data indication information is used to indicate that the data packet is a new data packet, and indicates QoS information for a group of data packets. The QoS information of the data packet group can be a QoS parameter identifier.
[00249] In addition, the new data indication information can be defined as follows: A bit is defined in a PDCP layer data packet header, and is used to indicate whether the data is new. For example, when a bit value is set to 1, it indicates that the data is new and, when the value is set to 0, it indicates that the data is not new.
Petition 870190068488, of 7/19/2019, p. 89/157
84/138 [00250] The new data packet means that the access network device does not configure an RB corresponding to the group of data packets. Correspondingly, after receiving the new data packet, the access network device configures an RB for the data packet group.
[00251] Specifically, the QoS request information may include part or all of the content of the corresponding QoS information from the data packet group whose transmission is requested in the first pre-authorized QoS information. For example, if the corresponding QoS information in the first pre-authorized QoS information received by the terminal does not include a QoS parameter, the QoS request information includes only a data packet group identifier, or otherwise, can include a data packet group identifier and a corresponding QoS parameter, or include only one QoS parameter corresponding to the data packet group. Alternatively, the QoS request information may include information of a reflective characteristic, in which the
information in feature reflective can include one parameter in Link QoS descendant of traffic and information in indication that is used for indicate an capacity in get a parameter QoS uplink
based on traffic downlink QoS parameter. Optionally, the reflective characteristic information may also include an upstream RB configuration of the traffic. In addition, optionally, the reflective characteristic information may also include information identifying the traffic slice, and the
Petition 870190068488, of 7/19/2019, p. 90/157
85/138 slice identification information includes at least one of the following: a slice ID, a slice type, a tenant type, a tenant identifier, a network function identifier, and the like.
[00252] Optionally, the QoS request information can include indication information that is used to indicate a type of obtaining QoS information, where the type of obtaining can obtain QoS information from the first pre-QoS information authorized (for example, obtaining a QoS parameter through mapping using a packet filter), or can obtain the QoS information based on the downlink QoS information.
[00253] The uplink QoS information obtained based on the downlink QoS information can include an uplink QoS parameter and a corresponding packet filter. Uplink QoS information can be obtained based on information about a downlink data packet. For example, the terminal inverts a 5-tuple IP of a downlink data packet header, that is, inverts a destination address and the source address, to obtain a packet filter from a group of data packets. uplink. An uplink QoS parameter and a downlink QoS parameter corresponding to the packet filter are the same, or the uplink QoS parameter and the downlink QoS parameter corresponding to the packet filter can also fulfill another rule mapping, and the core network control plan device can notify the endpoint of the mapping rule in advance.
Petition 870190068488, of 7/19/2019, p. 91/157
86/138 [00254] Furthermore, when the indication information indicates that the type of obtaining QoS information is to obtain the QoS information based on the downlink QoS information, the QoS request information may also include information of QoS of a downlink data packet group or a downlink data packet group identifier, where the QoS information and the downlink data packet group identifier are each corresponding to the information of Uplink QoS. The downlink data packet group identifier can be one of a carrier identifier, a service identifier, a flow identifier, a channel identifier, a radio carrier identifier and the like corresponding to the data packet group downlink.
[00255] Optionally, the QoS request information can also include PDU session information from the data packet group. The PDU session information can include at least one of the following: an access point name (English: Access Point Name, APN for short); a GW PDN identifier; a GW PDN address (either an IP address or a non-IP address); an IP address allocated by a GW PDN to the terminal; a session identifier; and a DN identifier.
[00256] Optionally, the QoS request information may also include slice identification information. The access network device uses slice identification information from a received data packet group as reference information from a radio resource configuration of the data packet group. Per
Petition 870190068488, of 7/19/2019, p. 92/157
For example, independent radio carriers can be configured for groups of data packets from different slices.
[00257] It should be noted that, step S707 is performed directly without step S702 to step S706 if the access network device has configured a radio carrier for the traffic of the terminal before the terminal starts traffic, for example, a radio bearer is pre-established based on the second pre-authorized QoS, or an uplink radio bearer is configured during the configuration of a downlink radio bearer.
[00258] Correspondingly, the access network device receives the QoS information.
[00259] S703. The access network device obtains QoS policy information from the core network control plan device.
[00260] QoS policy information includes pre-authorized QoS information. In addition, in a scenario of supporting reflective QoS, the QoS policy information also includes a reflective QoS rule, in which the reflective QoS rule is used to indicate a way to obtain the uplink QoS information based on downlink QoS information. The core network control plan device can notify the access network device and the end of the reflective QoS rule. For example, the core network control plan device notifies the access network device and the terminal in a PDU session establishment process, or in an initial UE context configuration process, or in another process
Petition 870190068488, of 7/19/2019, p. 93/157
88/138 signaling interaction between UE and the core network control plan device. It should be noted that there is no sequence between step S703 and steps S701 and S702, and the access network device can obtain QoS policy information after receiving QoS request information, or obtain policy information in advance of QoS.
[00261] Specifically, in a scenario of supporting reflective QoS, the method may also include:
[00262] Step 1: When a downlink traffic is established, the core network control plan device notifies the access network device of a downlink QoS parameter of the traffic, and indicates that the traffic has a reflective characteristic (English: reflective). In other words, a traffic uplink QoS parameter can be obtained based on the traffic downlink QoS parameter.
[00263] In addition, the core network control plan device can notify the access network device of the downlink QoS parameter of the traffic in a control plan or user plan manner.
[00264] Step 2: the access network device sends traffic-reflective characteristic information to the terminal.
[00265] Specifically, the access network device can notify the terminal of the traffic reflective characteristic information in one of the following ways:
[00266] In a first way, the terminal is notified in a user plan manner.
[00267] For example, characteristic information
Petition 870190068488, of 7/19/2019, p. 94/157
Reflective 89/138 is carried in a data packet header of a PDCP layer. Alternatively, reflective characteristic information can be carried in a header from another protocol layer, for example, carried in a header from an RLC layer or a MAC layer.
[00268] In a second way, the terminal is notified in a control plan manner.
[00269] For example, the reflective characteristic information is sent to the terminal using an RRC message, and the message explicitly indicates that the traffic has a reflective characteristic. Alternatively, an implicit way can be used, and a radio carrier uplink configuration is used to indicate that the traffic has a reflective characteristic. To be specific, if the access network device carries the uplink configuration of the radio carrier in the reflective characteristic information, it indicates that the traffic has a reflective characteristic.
[00270] In this modality, the terminal can obtain the QoS information in two ways, that is, to obtain the uplink QoS information based on the first pre-authorized QoS information and based on the downlink QoS information. In this case, the terminal can obtain the QoS information by using information obtained later. Specifically, if the terminal first receives the first pre-authorized QoS information and then receives the reflective characteristic information, the uplink QoS information includes the QoS information obtained based on the link QoS information
Petition 870190068488, of 7/19/2019, p. 95/157
90/138 downward, or if the terminal first receives the reflective characteristic information and then receives the first
information pre-authorized QoS information, the QoS information of
uplink includes at least part of the first pre-authorized QoS information.
[00271] S704. The access network device checks, based on the QoS policy information, the QoS information reported by the terminal. If the check is successful, S706 is performed; or otherwise, S705 is executed.
[00272] When the uplink QoS information is pre-authorized QoS information, the QoS check is to verify that a match between a QoS parameter and a data packet filter is correct. When the
information uplink QoS is reflective QoS,
QoS verification is to verify if the mapping form satisfies the reflexive QoS rule.
[00273] S705. The access network device sends a message to the terminal to indicate that the QoS information is wrong.
[00274] The access network device, in step S705, notifies the terminal that the QoS information is wrong and does not configure a radio resource.
[00275] S706. The access network device configures a radio resource for a group of data packets, and sends radio resource configuration information to the terminal.
[00276] Specifically, the access network device can configure the radio resource for the data packet group based on the uplink QoS information
Petition 870190068488, of 7/19/2019, p. 96/157
91/138 in the QoS request information. Correspondingly, the terminal receives the radio resource configuration information.
[00277] See step 502 for a specific implementation process in which the access network device configures the radio resource for the data packet group and the details are not described here.
[00278] S707. When initiating traffic, the terminal sends traffic data to the access network device based on radio resource configuration information using a radio carrier corresponding to the group of data packets.
[00279] See step S507 for a specific implementation process for step 707, and the details are not described here again.
[00280] S708. The access network device receives data that is sent by the terminal using the established radio carrier, and sends the received data to a core network user plan device.
[00281] See step S508 for a specific implementation process for step S708, and the details are not described here again.
[00282] Furthermore, in addition to a way in step S508 of obtaining, by the access network device, the PDU session information corresponding to the data pack, the PDU session information corresponding to the data pack can also be obtained as follows: The QoS request information carries the PDU session information, and the PDU session information corresponding to the data packet is obtained directly from the
Petition 870190068488, of 7/19/2019, p. 97/157
92/138 QoS request information.
[00283] In this modality, a carrier of a group of data packets corresponding to QoS is established using a QoS request and verification between the terminal and the access network device, so that new traffic can be quickly established between the terminal and the access network device. Compared with an existing traffic establishment procedure, in this mode, fast data transmission can be implemented, an uplink data transmission latency can be reduced, and the user experience can be improved.
[00284] Referring to Figure 8, Figure 8 shows another method for communication according to an embodiment of the present invention. The method is implemented using the system shown in Figure 1. In the mode shown in Figure 8, the method includes the following steps.
[00285] S801. During the establishment of traffic, a core network control plan device sends a downlink QoS parameter and an upstream traffic QoS parameter to an access network device, and indicates that the traffic has a reflective feature.
[00286] Having a reflective characteristic means the ability to obtain an uplink QoS parameter
of traffic based on a parameter in QoS of link downward traffic. [00287] S802. 0 network device in access send the information characteristic reflective of traffic to
terminal.
Petition 870190068488, of 7/19/2019, p. 98/157
93/138 [00288] The reflective characteristic information includes the traffic downlink QoS parameter and indication information that is used to indicate an ability to obtain traffic link uplink quality based on the downlink quality traffic parameter set.
[00289] Optionally, the reflective characteristic information may also include an RB configuration of uplink traffic.
[00290] In step S802, the traffic reflective characteristic information can be sent to the terminal in a control plane or user plane manner. See the related description in the modality shown in Figure 7 for a specific implementation process, and detailed description is omitted here.
[00291] Optionally, the core network control plan device can update the traffic's QoS information, and send updated QoS information to the access network device. Correspondingly, the method of this modality can also include:
receive, through the terminal, updated reflective characteristic information sent by the access network device, and update the reflective characteristic information stored locally based on the updated reflective characteristic information.
[00292] Specifically, if the traffic reflective characteristic information is sent in a user plan manner, correspondingly, the updated traffic reflective characteristic information is updated using an indication carried by a packet header
Petition 870190068488, of 7/19/2019, p. 99/157
94/138 different, for example, the updated reflective characteristic information is updated to have no reflective characteristic. If the traffic reflective characteristic information is sent in a control plane manner, correspondingly, the updated traffic reflective characteristic information is updated using RRC signaling, for example, the updated reflective characteristic information is updated to have no characteristic reflective.
[00293] S803. When starting the traffic, the terminal sends traffic data based on the reflective characteristic information.
[00294] Specifically, refer to the related content in the modality shown in Figure 7 for specific implementation of step S803, and the detailed description is omitted in this document.
[00295] It should be noted that if the core network control plan device or the access network device still notifies the traffic uplink QoS information terminal, the terminal can obtain the QoS parameter of two ways. In this case, the terminal can obtain the QoS parameter using information obtained later. For example, if the terminal is first notified of the reflective characteristic information, and then receives the uplink QoS information that is notified by the core network control plan device, the terminal obtains the QoS parameter using the uplink QoS information that is notified by the core network control plan device.
[00296] This embodiment of the present invention can still
Petition 870190068488, of 7/19/2019, p. 100/157
95/138 include a traffic release procedure. Specifically, the traffic release procedure includes the following two ways.
[00297] First way (the terminal causes a release of traffic):
[00298] Referring to Figure 9a, in the first way, the method for communication in this mode also includes the following steps.
[00299] Step S901a. The terminal detects whether traffic is terminated.
[00300] Specifically, step S901a can include:
detect, by the terminal, if an end-of-traffic instruction for an application layer is received, and when the end-of-traffic instruction is received, determine that the traffic is terminated; or when a traffic data volume is zero or less than a specified threshold, start a timer from the terminal, and if the traffic data volume is not increased when the timer expires, determine that the traffic is terminated; or if the traffic data volume is increased before the timer expires, reset the timer, and restart the timer the next time the traffic data volume is zero or less than the specified threshold.
[00301] The timer can be set by the core network control plan device, it is carried on the first pre-authorized QoS information, and is sent to the terminal (for example, it is sent to the terminal by using a message of NAS); or the timer can be set by the access network device, and the timer
Petition 870190068488, of 7/19/2019, p. 101/157
96/138 is sent to the terminal using an RRC message or a user plan control PDU.
[00302] During implementation, different timer values can be configured for different traffic, and the timer can be used for uplink traffic and downlink traffic, or used only for uplink traffic or link traffic downward.
[00303] In addition, the specified threshold can be configured using the same way as the timer, and the detailed description is omitted in this document.
[00304] Step S902a. Upon detecting that traffic is terminated, the terminal sends a traffic termination request to the access network device.
[00305] The traffic termination request can be sent in a control plan or user plan manner. The control plan way can be a way of using an RRC message, where the RRC message includes QoS information from a group of data packets that needs to be finalized, and referral information to request traffic termination, and the information QoS parameter is a QoS parameter identifier. The user plan way can be a way of using a data packet that indicates that traffic ends. For example, a PDCP PDU is generated in a PDCP layer and the PDCP PDU is defined as a final marker PDU, to indicate that traffic ends. Alternatively, the PDCP PDU carries a QoS parameter identifier and traffic termination indication information, or a PDCP PDU format is used to indicate that the traffic is terminated.
Petition 870190068488, of 7/19/2019, p. 102/157
97/138 [00306] In addition, the access network device can be notified using an RLC PDU or MAC PDU, where the RLC PDU or MAC PDU carries a QoS parameter identifier and completion indication information traffic, or a PDU format is used to indicate that traffic is terminated.
[00307] In another implementation, the terminal sends a RB release request message to the access network device only when all services of a radio carrier corresponding to the terminal are terminated. The message carries an RB identifier and also carries a cause value of an RB release request, for example, one traffic ends or all traffic ends. The terminal does not send a traffic termination request to the access network device to terminate a single traffic, but only initiates a radio carrier release request.
[00308] The terminal can still notify the network device of access in a user plan manner, and can use a data packet that indicates that the traffic ends. For example, a PDCP PDU is generated in a PDCP layer, and the PDCP PDU is defined as a final marker PDU, to indicate that traffic ends, or the PDU carries all QoS parameter identifiers and termination indication information. traffic, or a PDU format is used to indicate that the traffic is terminated. Alternatively, the PDU can carry an RB identifier. In addition, the PDU does not carry the QoS parameter identifier, to indicate that all traffic carried on the RB is terminated.
Petition 870190068488, of 7/19/2019, p. 103/157
98/138 [00309] Step S903a. The access network device receives the traffic termination request, releases a radio resource configuration from the traffic according to the traffic termination request, and sends an indication to release the traffic radio resource configuration to the terminal .
[00310] After receiving the traffic termination request, the access network device finishes configuring the radio resource for a group of traffic data packets. The access network device initiates a radio resource configuration release from the data packet group to the terminal, and can notify the terminal using an RRC message or a user plan PDU.
[00311] Step S904a. The terminal releases the radio resource configuration from the traffic according to the indication of releasing the radio resource configuration sent by the access network device.
[00312] The release indication may include the release of a data packet group identifier or a radio resource QoS parameter identifier.
[00313] Specifically, step S904a can include:
release, through the terminal, a correspondence between a group of data packages and a radio carrier.
[00314] If the data packet group is a last group of radio carrier data packets, a release of the radio resource configuration includes the release of the radio carrier. The terminal receives the indication of release and releases the radio carrier. The release indication includes the release of a radio carrier identifier.
Petition 870190068488, of 7/19/2019, p. 104/157
99/138 [00315] In addition, the access network device may not instruct the terminal to release correspondence between a group of data packets and a radio carrier, but only instruct the terminal to release a radio carrier.
[00316] If the radio bearer is the last radio bearer of the terminal, the release indication may be an RRC link release message. The terminal receives the indication of release, and releases an RRC link.
[00317] Second way (the access network device triggers a traffic release):
[00318] Referring to Figure 9b, in the second way, the method for communication in this mode also includes the following steps.
[00319] Step S901b. The access network device detects whether traffic has been terminated.
[00320] Specifically, the access network device determines the termination of a traffic (which can be an uplink traffic or a downlink traffic) using a timer. When a traffic data volume is zero or less than a specified threshold, the access network device starts the timer and, if the traffic data volume is not increased when the timer expires, it indicates that the traffic is terminated; or if the traffic data volume is increased before the timer expires, the access network device resets the timer, and resets the timer the next time the traffic data volume is zero or less than the specified threshold.
[00321] The timer can be set in one of the following two ways:
Petition 870190068488, of 7/19/2019, p. 105/157
100/138 [00322] In a first way, the core network control plan device sets the timer, the timer is included in pre-authorized QoS information, and the core network control plan device sends the pre-authorized QoS information for the access network device. Of course, the timer can also be included in another message and sent to the access network device.
[00323] In a second way, the access network device sets the timer.
[00324] The threshold for triggering a timer start can be defined by the core network control plan device or the access network device.
[00325] Method 1: the core network control plan device sets the threshold to trigger the timer start, the threshold is included in the pre-authorized QoS information or other message, and the core network control plan device sends the pre-authorized QoS information or other message to the access network device.
[00326] Method 2: the access network device sets the threshold to trigger the start of the timer and the access network device determines the end of a traffic using the timer.
[00327] Step S902b. The access network device releases a radio traffic resource configuration and sends an indication to release the radio traffic resource configuration to the terminal.
[00328] See step S903a for a specific process, and the detailed description is omitted in this
Petition 870190068488, of 7/19/2019, p. 106/157
101/138 document.
[00329] Step S903b. The terminal receives the radio traffic resource release indication, and releases the radio traffic resource configuration according to the radio resource configuration release indication sent by the access network device.
[00330] See step S904a for a process specific, and the detailed description is omitted in this document. [00331] In addition, the network access can
not instruct the terminal to release a correspondence between a group of data packets and a radio carrier, but only instruct the terminal to release a radio carrier.
[00332] In addition, if the radio bearer is the last radio bearer of the terminal, the release indication may be an RRC link release message.
[00333] In accordance with this implementation, the access network device and / or the terminal detects / detects the termination of traffic using the timer and releases / releases a radio resource configured for the traffic. In comparison to the prior art in which a traffic release is notified in a signaling manner, in this implementation, overloads of a traffic termination notification message are reduced, and the radio resource is released in a timely manner, thereby improving the use of radio resources and improving the capacity of the network.
[00334] It should be noted that, the traffic release procedures shown in Figure 9a and Figure 9b can
Petition 870190068488, of 7/19/2019, p. 107/157
102/138 be combined with the modalities shown in Figure 5, Figure 6, Figure 7 and Figure 8.
[00335] Referring to Figure 10, Figure 10 shows another method for communication according to an embodiment of the present invention. The method is implemented using the system shown in Figure 1. In the modality shown in Figure 10, a NAS PDU carries user data to implement a fast start of uplink traffic. The method includes the following steps.
[00336] S1001. A terminal sends an AS message to an access network device.
[00337] The AS message carries a NAS PDU, and the NAS PDU includes user data.
[00338] The AS message can be an RRC message, and the RRC message includes one of an RRC connection request, an RRC connection re-establishment request, an EU information response message and the like.
[00339] In addition, the NAS PDU includes session information, and the access network device routes the NAS PDU to a target core network control plan device based on the session information.
[00340] S1002. The access network device receives the AS message, and forwards a NAS PDU to a core network control plan device.
[00341] Using S1001 and S1002, user data can be transported on the NAS PDU and sent to the core network control plan device.
[00342] S1003. The core network control plan device detects user data on the NAS PDU, and determines the QoS information corresponding to the user data.
Petition 870190068488, of 7/19/2019, p. 108/157
103/138 [00343] Specifically, the QoS information corresponding to the user data can be determined with reference to policy information.
[00344] The content of the QoS information can be the same as that of the second QoS information pre-authorized in step S501, and the detailed description is omitted in this document.
[00345] S1004. The core network control plan device notifies a core network user plan device, the access network device and the QoS information terminal.
[00346] Optionally, the method also includes: notifying, via the core network control plan device, the QoS information terminal. The terminal can be notified of a part of the QoS information, for example, only a filter of QoS package and a maximum rate parameter.
[00347] S1005. The core network control plan device obtains user data from a NAS layer PDU, and sends the user data to an application server.
[00348] In an implementation, S1005 may include: direct user data to the application server, through the core network control plan. In this implementation, the core network control plan device can establish a data channel between the core network control plan device and the application server for the terminal, and this data channel can be in the form of a IP tunnel. The core network control plan device can establish the data channel to the terminal in a terminal attachment process, maintain the data channel, and release the data channel when
Petition 870190068488, of 7/19/2019, p. 109/157
104/138 the terminal is detached.
[00349] In another implementation, S1005 may include: sending, via the core network control plan device, the user data to the core network user plan device, so that the user plan device from core network sends the user data to the application server. A data channel between the core network user plan device and the application server is established, and the core network control plan device can establish the data channel for the terminal in the terminal attachment process, maintain the data channel, and release the data channel when the terminal is detached.
[00350] S1006. The access network device receives the QoS information sent by the core network control plan device, and configures a radio resource for traffic based on the received QoS information.
[00351] S1007. The access network device sends radio resource configuration information to the terminal.
[00352] See step S502 for specific implementation processes of steps S1006 and S1007, and detailed description is omitted here.
[00353] S1008. The terminal receives the radio resource configuration information sent by the access network device, and sends data based on the radio resource configuration information.
[00354] See the related description in the modality shown in Figure 5 for a specific process, and detailed description is omitted here.
Petition 870190068488, of 7/19/2019, p. 110/157
105/138 [00355] In addition, the radio resource configuration information can further indicate which radio carrier is a standard radio carrier. The default radio carrier can be established for each session, and is configured to carry standard QoS traffic.
[00356] In this modality, the terminal sends initial traffic data to a precise core network control plan device using a NAS, so that an uplink data transmission speed can be increased and a traffic start is accelerated, thus improving the user experience.
[00357] Referring to Figure 11, Figure 11 shows another method of communication according to an embodiment of the present invention. The method is implemented using the system shown in Figure 1. In the mode shown in Figure 11, data is sent using a common carrier. The method includes the following steps.
[00358] S1101. In a PDN connection process, a core network control plan device interacts with an access network device to establish a common carrier between a core network user plan device and the access network device .
[00359] The common carrier is a user plan data channel, and is configured to transmit a data packet between the access network device and the core network user plan device. Specifically, the common carrier is a data channel other than a data channel, corresponding to a standard carrier, between the access network device and the core network user plan device, and is configured to transmit
Petition 870190068488, of 7/19/2019, p. 111/157
106/138 traffic data for which no QoS has been configured. For example, new data triggered by uplink traffic from the terminal can first be sent to the core network user plan device, and QoS information can be configured later, and data sent first to the plan device Core network user accounts are traffic data for which no QoS has been configured.
[00360] During implementation, the common carrier can be established based on a PDU session. In other words, each session corresponds exclusively to a common carrier. The common carrier can also be established based on a node. In other words, the access network device and the access network user plan device correspond uniquely to a common carrier.
[00361] The standard carrier is applicable to non-GBR traffic. When new traffic is established, if the standard carrier cannot carry the traffic, a new dedicated carrier needs to be established for the traffic. Before the new dedicated carrier is established, data for the new traffic is sent using the common carrier.
[00362] Step S1102. When a terminal needs to send user data for new traffic, the terminal sends user data for new traffic to the access network device.
[00363] The new traffic is traffic for which no QoS parameters have been configured.
[00364] Specifically, the terminal can send the user data of the new traffic to the network device of
Petition 870190068488, of 7/19/2019, p. 112/157
107/138 access in any of the following ways:
[00365] First way: User data for new uplink traffic is sent using an SRB, for example, using an SRB1 or an SRB2 or a new SRB.
[00366] Specifically, the terminal can send the new user data using the SRB after an RRC connection is established. For example, a message 1 can be newly defined, and message 1 is used especially to send user data, of the new traffic, for which no QoS has been configured. In addition, message 1 further includes session information from user data, where session information may include at least one of the following: an APN; a GW PDN identifier; a GW PDN address (either an IP address or a non-IP address); an IP address allocated by a GW PDN to the terminal; a session identifier; and a DN identifier. In addition, the newly defined message 1 also includes new data indication information, used to indicate that the data packet is a new data packet, namely, a data packet for which no QoS parameters have been configured. Specifically, the new data indication information can be carried using a message name or message content.
[00367] Second way: the access network device establishes, for each terminal, a radio carrier specially for transmitting user data for which QoS has not been configured, and the terminal transmits, on the data carrier, all packets of data. user data for which no QoS has been configured, where session information is carried in an interface data packet header
Petition 870190068488, of 7/19/2019, p. 113/157
108/138 aerial. Specifically, the session information can be carried in an unoccupied field of an IP header of an air interface data packet, or a protocol header can be added outside an IP packet data layer, and the session information is carried in the protocol header. Alternatively, the session information is carried in a PDCP protocol header. It should be noted that, if the radio data carrier is established corresponding to each session, namely, a DRB is established for each session, the data packet header does not need to load the session information.
[00368] Third way: the access network device establishes a DRB for the terminal corresponding to each session, and the terminal transmits, on the radio carrier, a new user data packet, for which QoS has not been configured, where new data indication information is carried in an air interface data packet header. Specifically, the new data indication information can be carried in an unoccupied field of an IP header of an air interface data packet; or a protocol header can be added outside a data packet IP layer, and the new data indication information is carried in the protocol header; or the new data indication information can be carried in a PDCP header, as shown in a black part in Figure 12a.
[00369] Step S1103. The access network device receives the data from the new traffic sent by the terminal, and sends the data received from the new traffic to the core network user plan device through a channel in the
Petition 870190068488, of 7/19/2019, p. 114/157
109/138 terrestrial side.
[00370] Specifically, for the first and third ways of step S1102 in which the terminal sends the user data of the new traffic to the access network device, the access network device can learn, based on the new indication information data, that the user data of the new traffic is a data packet, of the traffic, for which no QoS parameters have been configured. For the second way of step S1102 in which the terminal sends the user data of the new traffic to the access network device, the access network device can learn, based on an attribute of the data radio carrier, that the User data for the new traffic is a traffic data packet, for which no QoS parameters have been configured.
[00371] In step S1103, the access network device first removes the new data indication information in the second and third ways, and then sends the data to the core network user plan device.
[00372] In this modality, the access network device can send the new traffic data to the core network user plan device using the common carrier, where the common carrier is configured exclusively to transmit the data packet, traffic, for which no QoS parameters have been configured. In addition, the session information can be carried in the data packet. Specifically, the session information can be carried in a tunnel protocol header. For example, if a GPRS Tunneling Protocol User Plane user plane tunnel,
Petition 870190068488, of 7/19/2019, p. 115/157
110/138
GTPU for short) is used, the session information is carried in a GTPU header. The session information can also be carried in an application layer IP header or in a transport layer IP header, as shown in a black part in Figure 12b.
[00373] In another embodiment, the access network device can send the new traffic data to the core network user plan device through a tunnel, and the data packet for which no QoS parameters have been configured, which is traffic and which is transmitted in the tunnel, carries new data indication information. Specifically, the new data indication information can be carried in a tunnel protocol header. If a GTPU tunnel is used, the new data indication information is carried in a GTPU header. Alternatively, the new data indication information can be carried in an application layer IP header or in a transport layer IP header. In this case, step S1101 does not need to be performed.
[00374] In addition, a common carrier or tunnel between the access network device and the core network user plan device can be established for each PDU session, and the access network device selects, based on a PDU session to which the new traffic data belongs, a common carrier or a corresponding tunnel for the PDU session, and sends the data.
[00375] Step S1104. The core network user plan device receives the new traffic data on the common carrier, and sends the new traffic data to a corresponding DN.
Petition 870190068488, of 7/19/2019, p. 116/157
111/138 [00376] Step S1105. The core network user plan device notifies the core network control plan device of the new traffic data.
[00377] Specifically, as the common carrier is configured exclusively to send data for traffic for which no QoS parameters have been configured, the core network user plan device can know that data transmitted on the common carrier is the data of the traffic for which no QoS parameters have been configured, and after receiving the data transmitted on the common carrier, sends the data to the core network control plan device, to trigger a QoS authorization process.
[00378] Step S1106. The core network control plan device generates authorized QoS information, and the core network control plan device sends QoS information to the core network user plan device, the access network device and to the terminal.
[00379] Step S1107. The access network device sets up a radio resource for new terminal traffic based on the QoS information.
[00380] After configuration, the access network device sends radio resource configuration information to the terminal. After receiving the radio resource configuration information, the terminal sends the new traffic data on the corresponding radio resource based on the radio resource configuration information, for example, transmits the data on a data carrier corresponding to the new traffic. Refer to the related description in the modality shown in Figure 5 for a
Petition 870190068488, of 7/19/2019, p. 117/157
112/138 specific process, and detailed description is omitted here.
[00381] Furthermore, in this mode, if QoS information such as a QoS parameter identifier is carried in a packet header of a data packet for which a QoS parameter is configured, a location that is in the header of the data packet and which carries the QoS parameter identifier can be set to null, to indicate that the data packet is new, that is, a data packet for which no QoS parameters have been configured.
[00382] In this modality, the terminal sends a new uplink data packet to the access network device, the access network device selects a target core network user plan device and sends the new data packet from uplink to the target core network user plan device based on the new data packet indication and / or data packet session information, to trigger a QoS authorization process, so that the new data is sent accurately to the target core network user plan device to initiate new traffic, thereby ensuring the normal initiation of a traffic establishment procedure.
[00383] The following are apparatus embodiments in embodiments of the present invention. Refer to the corresponding corresponding method modalities above for details that are not specifically described in the device modalities.
[00384] Figure 13 is a block diagram of an apparatus for communication in accordance with an embodiment of the present invention. The communication device can be implemented
Petition 870190068488, of 7/19/2019, p. 118/157
113/138 as a whole or as part of a terminal using a dedicated hardware circuit or a combination of software and hardware. The communication apparatus includes a receiving unit 1320 and a sending unit 1340. The receiving unit 1320 is configured to receive the first QoS information before the terminal initiates traffic. The sending unit 1340 is configured to: when the terminal initiates traffic, send, based on the first QoS information received by the receiving unit 1320, traffic data for using a radio resource that is configured by a network device. access for traffic, where the radio resource is configured by the access network device based on the second QoS information and both the first QoS information and the second QoS information are configured by a flat core network control device for terminal traffic before the terminal starts traffic.
[00385] The first QoS information includes at least one of the first pre-authorized QoS information and reflective characteristic information, and the reflective characteristic information includes a traffic downlink QoS parameter and indication information that is used to indicate a capacity for reflection.
[00386] Optionally, the sending unit 1340 is further configured to send request for QoS information to the access network device, so that the access network device configures a radio resource for the traffic of the terminal based on QoS request information.
[00387] In addition, the QoS request information
Petition 870190068488, of 7/19/2019, p. 119/157
114/138 can include uplink QoS information, where uplink QoS information includes at least part of the first pre-authorized QoS information, or uplink QoS information includes a QoS parameter obtained based on traffic downlink QoS parameter. Optionally, the QoS request information further includes at least one PDU protocol data unit session information and traffic slice identification information.
[00388] Furthermore, if the receiving unit 1320 first receives the first pre-authorized QoS information and then receives the reflective characteristic information, the uplink QoS information includes the QoS parameter obtained based on the QoS parameter downlink traffic, or if the receiving unit 1320 first receives the reflective characteristic information and then receives the first pre-authorized QoS information, the uplink QoS information includes at least part of the first pre QoS information -authorized.
[00389] Optionally, the receiving unit 1320 is further configured to receive updated reflective characteristic information sent by the access network device, where the updated reflective characteristic information is carried in a data packet header or is sent by using signaling radio resource control RRC.
[00390] Optionally, the receiving unit 1320 is further configured to receive the first updated pre-authorized QoS information sent by the core network control plan device, where the first information of
Petition 870190068488, of 7/19/2019, p. 120/157
115/138
Updated pre-authorized QoS is sent by the core network control plan device in an area update procedure or a process in which the terminal is transferred between different access network devices.
[00391] Optionally, the device also includes a 1360 processing unit. In one implementation, the 1360 processing unit is configured to filter traffic data using a packet filter indicated by the first pre-authorized QoS information. Therefore, the sending unit 1340 is configured to send, to the access network device by using a radio carrier corresponding to the packet filter indicated by the first QoS information, the data packet selected by the processing unit. In another implementation, processing unit 1360 is configured to determine a radio carrier corresponding to the traffic, and sending unit 1340 is configured to send traffic data to the access network device by using the radio carrier determined by processing unit.
[00392] In an implementation of this modality, the device also includes a 1380 detection unit. The 1380 detection unit is configured to detect whether traffic is terminated. Correspondingly, the sending unit 1340 is further configured for: when the terminal detects that traffic is terminated, send a request to terminate traffic to the access network device, or when the terminal detects that traffic corresponding to the same carrier radio stations are finalized, send a radio carrier release request to the
