“INFORMATION TRANSMISSION METHOD, APPLIANCE, COMPUTER-READABLE STORAGE MEDIA, COMMUNICATIONS SYSTEM, COMMUNICATIONS CHIP SYSTEM, BASE STATION AND USER EQUIPMENT”
TECHNICAL FIELD [001] This request refers to the field of communications and, in particular, to a method and apparatus for transmitting information.
BACKGROUND [002] A quality of service (QoS) mechanism is a network security mechanism. A network device processes data with different priorities using the QoS mechanism, to help prevent problems, such as network latency and network congestion.
[003] In a Long Term Evolution (LTE) system, a main network device maps different flows to carriers of the evolved packet system, EPS. An EPS carrier includes an S1 carrier and a data radio bearer (data radio bearer, DRB). The main network device communicates with a base station using the S1 carrier, and the base station communicates with a terminal device using the DRB. In a dual connectivity (DC) situation, when a master base station determines the transfer of a DRB to a secondary base station, the master base station needs to notify the primary network device of a DRB identifier to be transferred to the secondary base station, so that the main network device establishes a transmission channel that corresponds to the DRB with the secondary base station.
[004] However, a communication system of ^the fifth generation (5th-generation, 5G) imposes a higher requirement on QoS management data, in other words, the QoS management more refined needs to be performed on the data. In the prior art, the transmission of DRB-based information between the master base station and the secondary base station does not meet a requirement of the 5G communications system for QoS management.

[00107] It should also be understood that, in this application, the master base station or the secondary base station can be a base transceiver station (base transceiver station, BTS) in a Code Division Multiple Access system ( code division multiple access, CDMA), or it can be a NodeB (NodeB, NB) in a broadband code division multiple access system (wideband code division multiple access, WCDMA), or it can be an evolved NodeB (evolutional node B, eNB) in an LTE system, or it can be a gNB (gNB) in an NR system. The preceding base stations are just an example of a description. The master base station or the secondary base station can alternatively be a relay station, an access point, a vehicle device, a body-worn device or other type of device. To facilitate the description, in this application, devices that provide the wireless communication function to the UE are collectively called a base station.
[00108] In this application, a main network device can be a network element of a next generation core network (NGC), or it can be a 5G core network device, 5G-CN ), or it may be another primary network device. The NGC network element can include, for example, a control plane network element (control plane, CP) and a user plane network element (user plane, UP). The main network device is not limited in this order, and any main network device that can carry out the method described in the modalities is covered by the scope of protection of this order. Furthermore, in this application, the main network device is sometimes referred to as a main network for brevity.
[00109] The antecedent communications system is just an example for description. A number of main networks and a number of secondary base stations are not limited to the number shown in Figure 1.
[00110] Figure 2 is a schematic diagram of a method of
Petition 870190057885, of 06/24/2019, p. 156/215
19/54 transmission of information, according to a modality. As shown in Figure 2, a method 200 includes the following steps.
[00111] S201. A master base station sends a request message to a secondary base station, where the request message includes identifying information for a flow, or the request message includes identifying information for a flow and a mapping relationship between the flow and a DRB.
[00112] S202. The master base station receives a response message from the secondary base station in response to the request message.
[00113] In this embodiment, when the master base station determines the transfer of at least one flow to the secondary base station (for ease of description, the at least one flow that the master base station requests to transfer to the base station secondary is called a first stream), the master base station sends a request message to the secondary base station. For example, the request message can be a request message for adding a secondary base station, and the request message is used to request the secondary base station to allocate, for the first flow, a resource used to transmit the first stream. For example, the request message can be signaling, or it can be a data packet.
[00114] The request message includes identification information of the first flow, and identification information of the first flow is used to identify the first flow. The secondary base station determines the first stream based on the identification information of the first stream. If the secondary base station admits (admit) the first stream, the secondary base station can determine a mapping relationship between the first stream and a DRB, so that the secondary base station can map the first stream to the DRB.
[00115] Alternatively, in addition to the identification information of the first flow, the request message additionally includes a mapping relationship that is between the first flow and a DRB and which is determined by the master base station. The secondary base station determines the first flow based on the identification information of the
Petition 870190057885, of 06/24/2019, p. 157/215
20/54 first flow. If the secondary base station supports the first stream, the secondary base station maps the first stream to the DRB based on the mapping relationship between the first stream and the DRB.
[00116] In this request, when the first flow includes at least two flows, the at least two flows may belong to the same PDU session, or they may belong to different PDU sessions. In addition, the secondary base station can admit all flows in the first flow, or it can admit some flows in the first flow. The flows supported by the secondary base station include a flow that is successfully established or modified by the secondary base station. Specifically, the stream may be a stream of a corresponding DRB configuration that is successfully established or modified by the secondary base station.
[00117] According to the method of transmitting information, provided in this modality, the master base station sends, to the secondary base station, identification information used to indicate at least one flow, or the master base station sends, for the secondary base station, identifying information used to indicate at least one flow and a mapping relationship between at least one flow and a DRB, so that the secondary base station can map flows to different DRBs based on requirements of flows QoS, thus implementing QoS management with less granularity.
[00118] Optionally, the identification information of the first flow includes a QoS mark of the first flow.
[00119] The master base station can directly use the QoS tag of the first flow to identify the first flow. Or the master base station can map the QoS tag to the identification information of the first stream, in which case the master base station needs to additionally notify the secondary base station and UE of a mapping relationship between the tag QoS and identification information for the first flow. The fact that the QoS tag is mapped to the identification information of the first stream can be as follows: For example, the indexes of received QoS tags are classified in sequence, where an index number is the identification information of the first stream. O
Petition 870190057885, of 06/24/2019, p. 158/215
21/54 antecedent method is just an example for the description. This modality is not limited to the same. Any method for identifying the first stream based on the QoS tag of the first stream is within the scope of protection of this request.
[00120] According to the information transmission method, provided in this modality, the master base station uses the QoS tag of the first flow as the identification information of the first flow, so that different flows can be directly distinguished, and QoS management with less granularity is implemented.
[00121] Optionally, the identification information of the first flow includes an identifier of a PDU session to which the first flow belongs.
[00122] For example, when the first flow includes two flows that belong to different PDU sessions, and the two flows have the same QoS tag, the master base station can map separately to flow identifiers, namely, the identification information of the first flow, identifiers of the PDU sessions to which the two flows belong, or directly use the identifiers of the PDU sessions to which the two flows belong as the identification information of the first flow, or use the QoS tag of each of the two flows and the identifiers of the PDU sessions to which the two flows belong as the identification information of the first flow, or map, to a flow identifier, the QoS mark of each of the two flows and an identifier of a PDU session to which the flow belongs and, in this case of mapping, the master base station needs to notify the secondary base station and the UE of the r mapping relationship. The preceding method is just an example for description. This modality is not limited to the same. Any method for identifying the first flow based on the PDU session identifier to which the first flow belongs is within the scope of protection of this request.
[00123] Therefore, according to the information transmission method, provided in this modality, the master base station uses the PDU session identifier to which the first flow belongs as the identification information of the first flow or uses the QoS of
Petition 870190057885, of 06/24/2019, p. 159/215
22/54 first flow and the PDU session identifier to which the first flow belongs as the identification information of the first flow, so that different flows can be distinguished directly, and the QoS management with less granularity is implemented.
[00124] Optionally, the request message additionally includes QoS characteristic information from the first flow.
[00125] QoS characteristic information includes at least one group of QoS characteristics. A group of QoS characteristics is a specific QoS requirement, and the QoS requirement may be, for example, a packet loss rate, a delay and a priority. Each QoS brand corresponds to a group of QoS characteristics.
[00126] According to the method of transmitting information, provided in this mode, the master base station sends the QoS characteristic information from the first flow to the secondary base station, so that the secondary base station can determine a first flow QoS requirement for a DRB based on the first flow QoS characteristic information.
[00127] Optionally, the request message additionally includes a DRB identifier available for the secondary base station.
[00128] In this modality, the master base station can determine the DRB to which the first stream is mapped, and indicate the mapping relationship between the first stream and the DRB to the secondary base station using indication information. The master base station may not map the first stream to the DRB, but it indicates to the secondary base station a DRB identifier to which the first stream can be mapped, and the secondary base station maps the first stream to the DRB. For example, the master base station can send a list of available DRB identifiers for the first stream to the secondary base station, and the secondary base station determines DRB identifiers to be used. The preceding method is just an example for description. This modality is not limited to the same.
[00129] Therefore, according to the information transmission method, provided in this modality, the master base station sends, to
Petition 870190057885, of 06/24/2019, p. 160/215
23/54 the secondary base station, the DRB identifier available for the secondary base station. The secondary base station can map the first stream to the DRB based on the DRB identifier available to the secondary base station, to avoid a conflict between a DRB mapped by the master base station and a DRB mapped by the secondary base station, and reduce the load on the master base station.
[00130] Optionally, the request message additionally includes a DRB identifier unavailable to the secondary base station.
[00131] The master base station can send, to the secondary base station, the DRB identifier unavailable to the secondary base station. For example, the master base station can send a list of DRB identifiers unavailable to the first stream to the secondary base station. For example, the master base station may indicate to the secondary base station a DRB identifier that is used by the master base station to avoid a conflict between a DRB mapped by the master base station and a DRB mapped by the base station. secondary base, and reduce the load on the master base station.
[00132] The preceding method is just an example for description. This modality is not limited to the same. For example, the master base station may additionally send a DRB identifier available for the first stream and an DRB identifier unavailable for the first stream to the secondary base station. The two identifiers can be sent to the secondary base station in two lists, or they can be sent to the secondary base station in one list, and the identifiers of different types of DRBs in a list can be distinguished using identifier bits .
[00133] The background information included in the request message is just an example for the description, and should not be understood as a limitation in this modality. The request message may additionally include other information. For example, the request message may additionally include tunnel endpoint information from the PDU session to which the first flow belongs on a primary network node. Tunnel endpoint information can be a
Petition 870190057885, of 06/24/2019, p. 161/215
24/54 general packet radio service tunneling protocol (GTP) tunneling endpoint identifier (GTP-TEID) and a transport layer address, or can be point information tunnel endpoint based on an Ethernet power protocol (power over Ethernet, PoE), or it can be tunnel endpoint information based on another transport layer protocol. This is not limited in this modality.
[00134] At S202, after receiving the request message sent by the master base station, the secondary base station performs configuration, and sends the response message in response to the request message (for example, to the master base station) , the response message can be a secondary base station add request response message). The response message is used to indicate a processing result performed by the secondary base station on the first stream. For example, when the secondary base station determines to reject the first stream, the reply message may include a bit that indicates that the first stream is rejected, or the reply message may include referral information used to indicate that an allocated resource for the first stream is 0. When the secondary base station determines to admit the first stream, the reply message can be used to indicate a resource allocated by the secondary base station for the first stream. As another example, the reply message includes two lists. One list includes information about a stream supported by the secondary base station, and the other list includes information about a stream rejected by the secondary base station.
[00135] Optionally, the response message includes identification information for a flow supported by the secondary base station and tunnel endpoint information that correspond to the flow admitted by the secondary base station.
[00136] When the secondary base station determines to admit the first flow, if the secondary base station admits some flows in the first flow, the response message includes identification information of the flows admitted in the first flow and tunnel endpoint information that correspond to the admitted flows. Optionally, if the
Petition 870190057885, of 06/24/2019, p. 162/215
25/54 secondary base admit all flows in the first flow, the response message can indicate, according to a bit, that the secondary base station admits all flows in the first flow, or can send identification information of the flows admitted in the first flow to the master base station.
[00137] Therefore, the master base station can determine, based on the response message, a flow that can be split to the secondary base station.
[00138] Optionally, the response message includes information identifying a flow that is not supported by the secondary base station.
[00139] If the secondary base station supports some flows in the first flow, the response message may include information identifying a flow that is not supported by the secondary base station in the first flow, so that the master base station can determine, based on the response message, a stream that can be split to the secondary base station. The preceding method is just an example for the description. This modality is not limited to the same. For example, the response message may include all of the flow identification information supported by the secondary base station, the tunnel endpoint information that corresponds to the flow supported by the secondary base station, and the identification information of the rejected flow by the secondary base station.
[00140] The information included in the reply message is just an example for the description, and should not be understood as a limitation in this modality. The preceding reply message may additionally include other information.
[00141] For example, the response message may additionally include tunnel endpoint information from the PDU session to which the first flow belongs at the secondary base station. The tunnel endpoint information can be a GTP-TEID and a transport layer address, or it can be tunnel endpoint information based on a PoE protocol, or it can be tunnel endpoint information based on another protocol of
Petition 870190057885, of 06/24/2019, p. 163/215
26/54 transport layer. This is not limited in this modality.
[00142] As another example, when the secondary base station determines the mapping relationship between the first stream and the DRB, the response message additionally includes indication information that indicates the mapping relationship.
[00143] As another example, when the master base station determines the mapping relationship between the first stream and the DRB, the response message additionally includes at least one among information about an accepted DRB and information about a rejected DRB. Information about a DRB includes a DRB identifier.
[00144] The reply message can include all the information described above, or it can include only a part of the information described above.
[00145] Optionally, in an implementation of this request, method 200 includes, additionally:
[00146] S203. The master base station sends, to a main network device, information identifying a flow supported by the secondary base station and tunnel endpoint information that corresponds to the flow supported by the secondary base station.
[00147] Alternatively, method 200 additionally includes: S204. The master base station sends, to a main network device, identification information for a flow supported by the master base station, tunnel endpoint information that corresponds to the flow admitted by the master base station, identification information for a flow supported by the secondary base station, and tunnel endpoint information that corresponds to the flow supported by the secondary base station.
[00148] In this embodiment, the master base station sends tunnel endpoint information to the main network device that corresponds to flows admitted by the base stations (which include the master base station and the secondary base station ) in flows included in a PDU session at base stations. Tunnel endpoint information that corresponds to base stations can be carried in a session definition reply message, or can be carried in a
Petition 870190057885, of 06/24/2019, p. 164/215
27/54 session modification indication message.
[00149] It can be understood that S203 and S204 are two optional execution steps, in other words, the master base station can perform S203 or S204.
[00150] When both tunnel endpoint information that corresponds to the master base station and tunnel endpoint information that corresponds to the secondary base station is carried in the session definition reply message, in a specific way, in a situation in which S204 can be performed, the session definition response message is used to indicate a PDU session definition status. The session definition response message includes at least one of the information about a PDU session that is successfully defined and information about a PDU session that is not successfully defined. For example, information about the PDU session that is successfully defined includes a PDU session identifier, a QoS tag and GTP-TEIDs, and transport layer addresses for a stream identified by the QoS tag at stations -base (which include the master base station and the secondary base station). Optionally, the session definition reply message additionally includes base station identifiers. Optionally, the session definition reply message can include only the flow identification information admitted by the secondary base station and the tunnel endpoint information that corresponds to the flow admitted by the secondary base station.
[00151] When the tunnel endpoint information that corresponds to the secondary base station is carried in the session modification indication message, in a specific way, in a situation in which the S203 can be performed, the indication indication message session modification is used to instruct the primary network device to migrate, to the secondary base station, the flow admitted by the secondary base station in the first flow. For example, the session change indication message includes a QoS tag and a GTP-TEID and a transport layer address for a stream identified by the QoS tag at the secondary base station. Optionally, the modification indication message
Petition 870190057885, of 06/24/2019, p. 165/215
The session may additionally include an identifier for a PDU session to which the stream identified by the QoS tag belongs. If the entire PDU session is migrated to the secondary base station, the session change indication message can include only the PDU session identifier, and a GTP-TEID and transport layer address of the PDU session on the secondary base station.
[00152] According to the method of transmitting information, provided in this modality, the base station sends to the main network device, tunnel endpoint information that corresponds to a flow included in the PDU session at the base station secondary, or the base station sends to the primary network device, tunnel endpoint information that corresponds to a flow included in the PDU session at the master base station and tunnel endpoint information that corresponds to the included flow in the PDU session at the secondary base station, so that a carrier can be created and transferred based on flow information.
[00153] Optionally, in an implementation of this request, method 200 includes, additionally:
[00154] S205. The master base station sends DRB configuration information to the UE, where the DRB configuration information includes a DRB identifier and identification information for a stream that corresponds to the DRB.
[00155] The DRB configuration information includes identification information of a flow that corresponds to each one among DRBs that correspond, respectively, to the master base station and the secondary base station, in a specific way, the DRB configuration information indicate DRBs to be established on the master base station and DRBs to be established on the secondary base station.
[00156] After receiving the response message from the secondary base station, or after sending the session definition response message or the session change indication message to the main network, the master base station sends a reconfiguration message Radio Resource Control (RRC) connection link to the UE. The RRC connection reconfiguration message includes the
Petition 870190057885, of 06/24/2019, p. 166/215
29/54 antecedent DRB configuration.
[00157] According to the information transmission method, provided in this modality, the UE can receive data (namely, a stream) from at least one between the master base station and the secondary base station based on the information of DRB configuration, and a carrier can be created and transferred based on flow information.
[00158] Optionally, before the master base station sends the request message to the secondary base station, method 200 additionally includes:
[00159] S206. The master base station receives a flow identifier from the user equipment.
[00160] S207. The master base station establishes, based on the flow identifier, a carrier for a flow indicated by the flow identifier.
[00161] The flow identifier is used to indicate the flow, and a specific shape of the flow identifier is not limited in this order. When the UE has data to be uploaded and cannot determine a mapping relationship between a stream and a DRB, the UE can send a stream identifier that corresponds to the data to a base station (which includes the master base station or the secondary base station), to request the base station to map a flow to a DRB to the flow indicated by the flow identifier. The way in which the user equipment determines the flow identifier that corresponds to the data is not limited in this order.
[00162] In an optional deployment, the flow identifier can be carried in an RRC request message. After receiving the RRC request message, the base station initiates a carrier establishment process that matches the flow identifier. The carrier may be a carrier established only at the master base station, or it may be a carrier established only at the secondary base station, or it may be a split bearer established at both the master base station and the secondary base station. .
[00163] In another optional deployment, the flow identifier can be sent to the base station together with uplink data. THE
Petition 870190057885, of 06/24/2019, p. 167/215
30/54 base station triggers, based on a pre-established command at the base station, a carrier establishment process that corresponds to the flow identifier. The carrier can be a carrier at the master base station, or it can be a carrier at the secondary base station, or it can be a split carrier.
[00164] When the base station determines the bearer establishment for the UE, the base station can perform the foregoing processes of S201 and S202 and another process used to establish a bearer for the UE in this order. The details are not described again in this document.
[00165] According to the information transmission method, provided in this modality, the base station establishes, based on the flow identifier received from the UE, the bearer for the flow indicated by the flow identifier, so that a bearer can be created and transferred based on flow information, and a requirement for a 5G communications system for managing information transmission QoS can be met.
[00166] The method of transmitting information, provided in this application, is described separately from a perspective of a base station, a main network and a terminal device in the previous mode. The following section further describes the modalities in detail based on a common aspect of the modality described above.
[00167] Figure 3 is a schematic flowchart of another method of transmitting information, according to a modality. As shown in Figure 3, the method includes the following steps.
[00168] S301. An NGC sends a session definition request message to a master base station, where the session definition request message carries at least one of the PDU session information. Specifically, the PDU session information includes a PDU session identifier, a GTP-TEID, a transport layer address and a NAS-level QoS description, and the NAS-level QoS description includes a characteristic QoS tag and a QoS tag. The GTP tunnel endpoint identifier and the transport layer address are used to identify a PDU session endpoint on a primary network node on a next interface.
Petition 870190057885, of 06/24/2019, p. 168/215
31/54 generation (NextGen, NG). In this case, elements of information included in the session definition request message can be shown in Table 1, or they can be in another form. This is not limited in this order.
Table 1

[00170] In Table 1, the description of NAS level QoS is used for QoS control, and data packets marked with the same QoS brand have the same QoS requirement. For a base station, different QoS brands identify different flows. In addition, a session
Petition 870190057885, of 06/24/2019, p. 169/215
32/54 PDU can include a plurality of flows, and at least one PDU session can be defined in a PUD session definition process.
[00171] S302. After receiving the session definition request message, the master base station determines to transfer some or all of the flows that correspond to the session definition request message to a secondary base station for transmission (specifically, the station master base makes a split decision). Optionally, the master base station can map the QoS tag to an identifier of a stream. Alternatively, the master base station can directly use the QoS tag to identify the stream, in which case a stream identifier is the QoS tag. It should be understood that, in this application, when both an identifier of a flow as a flow identification information is used to indicate the flow, the two can be used interchangeably.
[00172] If the QoS tag is not unique between PDU sessions, specifically, PDU sessions can have the same QoS tag, a QoS tag for a flow, and a PDU session identifier for a PDU session to which the flow belongs can be mapped to a flow identifier. Alternatively, a QoS tag for a flow and a PDU session identifier for a PDU session to which the flow belongs are used to identify the flow, in which case a flow identifier is the QoS identifier and the PDU session. In this order, the flow identifier can be any one of the previous cases.
[00173] S303. The master base station sends a request to add a secondary base station to the secondary base station, where the message carries at least one of the flow information, and the flow information can include a QoS tag from one flow, a flow QoS characteristic, a GTP tunnel identifier and a transport layer address of a PDU session to which the flow belongs on a main network node and, optionally, can additionally include a PDU session identifier. In this case, a specific information element design can be described in Table 2 and Table 3, or it can be in another form. This is not limited in this order.

[00176] If the master base station performs mapping from the stream to a DRB, a mapping relationship between the DRB and the stream is also carried in the message. In this case, at least one flow can be mapped to a DRB, and at least one flow can belong to the same PDU session, or it can belong to different PDU sessions. In this case, an information element design can be shown in Table 4 to Table 6, or it can be in another form. This is not limited in this order. A PDU session identifier is optional.

36/54 a stream to a DRB for the stream to be split to the secondary base station, but the secondary base station performs the mapping, in this case, to prevent a conflict from occurring in DRBs, the master base station needs to send an indication to the secondary base station. The indication is used to indicate a DRB identifier that can be configured for the secondary base station.

[00208] S501. The UE determines a first DRB based on information identifying the first data.
[00209] S502. The UE sends the first data using the first DRB.
[00210] In this modality, the first data is uplink data, the identification information of the first data includes at least one among the information of a flow identifier (for example, a QoS mark) of the first data and an identifier of a PDU session to which the first data belongs, and the UE determines, based on the identification information of the first data, a DRB that corresponds to the identification information, namely, the first DRB. The first DRB can be a DRB carried by a master base station, or it can be a DRB carried by a secondary base station. A match between the identification information of the first data and the DRB can be pre-configured information in the UE, or it can be information determined by the UE based on a match between a QoS tag of a downlink data stream and a DRB , or it may be information determined by the UE in another way.
[00211] Therefore, according to the method of information transmission, provided in this modality, the UE can determine, based on an uplink data stream identifier and an PDU session identifier, a DRB that corresponds to a QoS requirement for uplink data, and a carrier can be created and transferred based on flow information.
[00212] Optionally, the fact that the UE determines a first DRB based on first data identification information includes:
[00213] S503. The UE determines that a standard bearer that corresponds to a PDU session identifier is the first DRB, where the identification information of the first data includes the PDU session identifier.
[00214] According to the method of transmitting information, provided in this modality, the standard carrier can be at the base station
Petition 870190057885, of 06/24/2019, p. 181/215
44/54 master, or it can be at the secondary base station. The UE can determine the DRB that corresponds to the QoS requirement of the uplink data without exchanging information with another network element, so that signaling overheads can be reduced.
[00215] When sending the uplink data using the standard bearer, the UE sends the flow identifier that corresponds to the uplink data to a base station. After receiving the uplink data sent by the UE using the standard bearer, the base station can map a stream to a DRB to uplink data sent subsequently by the UE, and notify the UE of a uplink relationship. mapping between a subsequently sent stream and a DRB. The DRB may be the previous standard carrier, or it may be a new carrier.
[00216] Optionally, the fact that the UE determines a first DRB based on first data identification information includes:
[00217] S504. The UE sends a first request message to a base station, where the first request message includes the information identifying the first data, and the first request message is used to request the base station to perform DRB mapping for the first data.
[00218] The DRB mapping for the first data includes: mapping the first data to another DRB in addition to the standard carrier. The other DRB can be an existing DRB, or it can be a newly created DRB. The other DRB can be a DRB at the master base station, or it can be a DRB at the secondary base station.
[00219] S505. The UE receives a response message from the base station, where the response message includes a mapping relationship between the first data and the first DRB.
[00220] According to the information transmission method, provided in this modality, the UE can send the first request message to the base station (the master base station or the secondary base station), in which the first message The request includes at least one of the information from a QoS tag and an identifier from a PDU session, and the first request message is used to request the
Petition 870190057885, of 06/24/2019, p. 182/215
45/54 base, to perform DRB mapping for data indicated by the QoS mark and the PDU session identifier. Therefore, the UE can determine the DRB that corresponds to the QoS requirement of the uplink data, and a carrier can be created or transferred based on flow information.
[00221] Optionally, method 500 additionally includes:
[00222] S506. The UE determines the identification information of the first data based on upper layer information and non-access stratum, NAS information.
[00223] An upper layer is an application layer of the UE, for example, an application program running in the UE. An access layer (Access Stratum, AS) of the UE can determine the identification information of the first data based on information from the upper layer or a NAS. The identification information of the first data includes the PDU session identifier that corresponds to the first data and the flow identifier (for example, the QoS tag) of the first data. The UE of the UE receives the identifier of the top layer PDU session, and the AS of the UE receives the identifier of flow of the first data from the NAS.
[00224] Specifically, the UE NAS can determine the QoS tag of the data based on a packet filter. The packet filter is a policy, and is used to determine, from data that includes a plurality of characteristics, data, namely, a flow that meets a specific rule.
[00225] The AS of the UE determines the DRB based on the identification information of the first data. If the identification information of the first data has no corresponding DRB, the UE of the AS determines the default bearer based on the PDU session identifier, and sends the first stream using the default bearer.
[00226] Therefore, according to the information transmission method, provided in this modality, the UE of the AS determines identification information of the uplink data based on the upper layer information and the NAS information, to determine, based on in the uplink data identification information, the DRB to send the uplink data.
