[00134] [00134] It can be understood that the above descriptions of functions of several modules are merely examples, and the modules may also have other functions. This is not limited in the embodiments of the present invention.
[00135] [00135] In some modalities, in an interoperation process between the 5G system and the EPS system when the terminal device is in an idle state, the terminal device can access the EPS system in an tracking area update (TAU). When the terminal device is in a connected state, a transfer procedure between the 5G system and the EPS system mainly includes the following two modes: In a first mode, in an interoperation process between the 5G system and the EPS, a context mapping of mobility management / section management (Mobility Management / Session Management, MM / SM) is performed on each one; in a second way, a solution to reestablish an MM / SM context in the process of transferring from EPS to 5G is supported.
[00136] [00136] In some modalities, a procedure for transferring from the 5G system to the EPS system specifically includes: When the 5G QoS flow is established in the 5G network, both an EPS QoS parameter and an identifier, ID), of EPS carrier are established. Establishing an EPS QoS parameter for an EPS carrier identifier includes: establishing a QoS standard EPS carrier that matches a standard 5G rule, and may also include: establishing a dedicated EPS carrier that matches a guaranteed bit rate QoS flow (Guaranteed Bit Rate, GBR) 5G.
[00137] [00137] Based on the interaction architecture between the 5G system and the EPS system, the modalities of this request provide a method of communication. A section of the EPS system can be established when a section of the 5G system is established according to a network requirement, so that establishing an EPS section can be determined based on a current condition, thereby avoiding the establishing an unnecessary EPS section, and improving communication efficiency.
[00138] [00138] The following describes a method of communication according to a modality of this request with reference to Figure 4. A method 400 in Figure 4 can be applied to any architecture in Figures 1 through Figure 3. Alternatively, a method in Figure 4 can be applied to another similar architecture. A first network can include an EPS system network or a 4G system network, and the second network can include a 5G system network. A first network element can be an SMF or an entity that has an SMF function. For example, the first network element can be an SMF + PGW-C module in architectures 100 to 300. A second network element can be an AMF or an entity that has an AMF function. A third network element can be a UDM or an entity that has a UDM function, for example, it can be a HSS + UDM module in architectures 100 to 300. A policy control network element can be a PCF or an entity that has a PCF function, for example, can be a PCF + PCRF module in architectures 100 to 300. Method 400 includes the following steps.
[00139] [00139] Step 401. The second network element sends first indication information to the first network element; correspondingly, the first network element receives the first indication information from the second network element, where the first indication information is used to indicate that a current condition supports the establishment of a section of the first network to a terminal device.
[00140] [00140] In some examples, that the current condition supports the establishment of the first network section for the terminal device may include: An N26 interface exists between a 5G system and an EPS system on a current network. In other words, a communications interface exists between an MFA in the 5G system and an MME in the EPS system. In addition, that the current condition supports the establishment of the first network section for the terminal device may also include: The terminal device is in a single register state.
[00141] [00141] For example, the first indication information may include first information, and the first information may indicate, in an explicit or implicit way, that the current condition supports the establishment of the first network section for the finished device. - final. In the explicit mode, the first information can directly indicate that a communications interface exists between a mobility management entity of the second network and a mobility management entity of the first network. For example, the first information is used to indicate that the current network supports an N26 interface between AMF and MME, or to indicate that a 5G network supports interaction with a 4G network. In the implicit mode, the first information can be a standard carrier identifier of the first network of the terminal device, and the carrier identifier of the first network of the terminal device can be used to implicitly indicate that the current condition supports the establishment of the section of the terminal. first network for the terminal device. The carrier identifier of the first network can be a carrier identifier designated from the first network, or it can be a standard carrier identifier of the first network. For example, the default carrier identifier for the first network can be a standard EPS carrier identifier for the terminal device, and the dedicated carrier identifier for the first network can be a dedicated EPS carrier identifier for the terminal device.
[00142] [00142] In this modality of this request, the first network element determines, based on the first information included in the first indication information, that the first QoS quality of service control information of a first section of the terminal device in the first network they need to be obtained, to determine, based on the first referral information, to establish the section of the first network, thereby avoiding the establishment of an unnecessary section of the first network and improving communication efficiency.
[00143] [00143] In this modality of this request, the standard carrier identifier of the first network of the terminal device is loaded in the first information, to implicitly indicate the content of the first information, thereby reducing excesses.
[00144] [00144] As mentioned above, that the current condition supports the establishment of the first network section for the terminal device may also include: The terminal device is in the unique registration state. If the terminal device is in the unique registration state, this indicates that the terminal device cannot register with both the first network and the second network at the same time. For example, the terminal device can register with only the 5G system or can register with only the EPS system. If the terminal device is in a dual registration state, this indicates that the terminal device can register with the first network and the second network at the same time. For example, the terminal device can register with the 5G network and the EPS network at the same time. If the current network supports the N26 interface, and the terminal device is in the state of single registration, the first network element determines that the section of the first network needs to be established for the terminal device. If the terminal device is in the dual registration state, that is, the terminal device establishes contexts with the first network and the second network at the same time, the terminal device can select any network at any time to perform service transmission. . For example, the terminal device establishes contexts in the 5G system and the EPS system at the same time.
[00145] [00145] In the case above, the first indication information may also include second information, and the second information is used to indicate that a terminal device is in the state of single registration.
[00146] [00146] In this modality of this request, the first indication information includes the first information and the second information. When the condition indicated by the first indication information is met, the section of the first network of the first section can be established while the section of the second network of the first section is established, thereby avoiding the establishment of an unnecessary section of the first network and improving communication efficiency.
[00147] [00147] In some examples, the receipt, by a first network element, of first information indicating a second network element may include: receiving, by the first network element, a message from the network management request. first section of the second network element, where the management request message of the first section includes the first indication information.
[00148] [00148] The management request message in the first section can include a plurality of types. For example, the first section management request message can include any of the following: a first session PDU session establishment request message.
[00149] [00149] Step402.0 The first network element obtains the first QoS control information from the first section of the terminal device after receiving the first indication information, where the first section is a section established by the terminal device using the second network.
[00150] [00150] The first QoS control information can be used to control the quality of service of a service transmitted on the first network. In other words, the first QoS control information can be control information related to the quality of service of a service transmitted on the first network. For example, the first QoS control information can include at least one of the following: a QoS parameter, a QoS parameter identifier, a packet filter, and packet filter priority information.
[00151] [00151] —Optionally, after obtaining the first indication information, the first network element can determine, based on the first indication information, if the section of the first network needs to be established for the terminal device. For example, after receiving the first indication information, the first network element can directly determine that the section of the first network needs to be established for the terminal device. Alternatively, after receiving the first indication information, the first network element can determine, based on the first indication information and other information, whether the section of the first network needs to be established for the terminal device. For example, the other information may be the third information.
[00152] [00152] —Optionally, method 400 also includes: obtaining, by the first network element, third information, where the third information is used to indicate that an attribute of the first section is to ensure continuity. The third piece of information can be section continuity mode information from the first section or section continuity mode and service information (SSC mode) from the first section.
[00153] [00153] —Optionally, the third information may indicate that the attribute of the first section is to ensure continuity or indicate that the attribute of the first section is that continuity does not need to be ensured. In some examples, the first network element stores the third information, or the first network element can obtain subscription data from an UDM. Subscription data obtained from UDM may include third party information. For example, the third information may be the SSC mode information. The first network element obtains the SSC mode information from the first section of the UDM. If SSC mode indicates that a section mode is a first mode, it may indicate that the first section is to ensure continuity. If SSC mode indicates which section mode is a second mode, it may indicate that the first section is that continuity does not need to be ensured.
[00154] [00154] In some examples, after obtaining the first indication information, the first network element can also determine whether the attribute of the first section is to ensure continuity. If the attribute of the first section is to ensure continuity, the first network element can determine that the section of the first network needs to be established.
[00155] [00155] In this modality of this request, when a network requirement indicated by the first indication information and a condition indicated by the third information are met, the first network section of the first section can be established while the second network section the first section is established, thereby avoiding the establishment of an unnecessary section of the first network and improving communication efficiency. When the third information indicates that the attribute of the first section is that continuity does not need to be ensured, the first network element does not need to establish the section of the first network for the terminal device, thereby reducing resources communications.
[00156] [00156] After the first network element determines, based on the first indication information, that the first network section needs to be established for the terminal device, the first network element can obtain the first QoS control information from the terminal device . For example, the first QoS control information is QoS control information for a service transmitted in the EPS system. The first QoS control information can include at least one of the following: the QoS parameter, the QoS parameter identifier, the packet filter, and the packet filter priority information. For example, the QoS parameter in the first QoS control information can be a QoS parameter of the terminal device's standard EPS carrier, or it can be a QoS parameter of the terminal device's dedicated EPS carrier. The packet filter and packet filter priority information are a traffic flow template (Traffic Flow Template,
[00157] [00157] The first network element can obtain the first QoS control information from the terminal device in at least two modes.
[00158] [00158] In a first mode, the first network element can obtain second QoS control information from a third network element, and determine the first QoS control information based on the second QoS control information. the first network element can determine the first QoS control information in two modes. In a first mode, the first network element can determine the second QoS control information as the first QoS control information without modifying the second QoS control information. In a second mode, the first QoS control information. network can send the second QoS control information to a policy control network element; after receiving the second QoS control information, the policy control network element can determine the first QoS control information based on the second QoS control information, where the first QoS control information is information authorized by a policy control unit. The policy control network element can modify the second QoS control information to obtain the first authorized QoS control information. Alternatively, the policy control network element may not modify the second QoS control information to obtain the first authorized QoS control information. The policy control network element can send the first authorized QoS control information to the first network element.
[00159] [00159] In a second mode, the first network element can receive the first QoS control information from a policy control network element, where the first QoS control information is information authorized by the network element. policy control. The policy control network element can obtain the first QoS control information in two modes. In a first mode, the policy control network element can generate the first QoS control information. In a second mode, the policy control network element can obtain third subscribed QoS control information from a fourth element of control. network, and the policy control network element can determine the first QoS control information based on the third QoS control information. Specifically, the policy control unit can select to modify or not modify the third QoS control information, to get the first QoS control information.
[00160] [00160] In the first mode, in some examples, the first network element sends a subscription data request message from the first section to the third network element, where the data request message is obtained subscription information includes fourth information, and the fourth information is used to request to provide subscription data for the first network; the first network element receives a subscription data response message from the first section of the third network element, where the subscription data response message includes the second QoS control information, and the second control information QoS trolley are subscribed; the first network element obtains the first QoS control information based on the second QoS control information.
[00161] [00161] In some examples, the fourth information may include a data network name (data network name, DNN), and indicate that the subscription data for the first network needs to be obtained. In some other examples, the fourth information may also include an access point name (APN) from the first network, to indicate that subscription data from the first network needs to be obtained.
[00162] [00162] In addition, obtaining, by the first network element, the first QoS control information based on the second QoS control information may include: determining, by the first network element, the second control information of QoS as the first QoS control information; or send, by the first network element, the second QoS control information to the policy control network element; and receive, by the first network element, the first QoS control information from the policy control network element, where the first QoS control information is based on the second QoS control information, and the first QoS control information is information authorized by the policy control network element.
[00163] [00163] In the second mode, in some examples, method 400 still includes: sending, through the first network element, an establishment request message from the first section to the policy control network element, where the request message from establishment of the first section includes fifth information, and the fifth information is used to instruct the policy control network element to establish the first network section; and the receipt, by the first network element, of the first QoS control information of a policy control network element includes: receiving, by the first network element, an establishment reply message from the first section of the policy element. policy control network, where the establishment response message
[00164] [00164] Step403.0The first network element sends the first QoS control information to the second network element; correspondingly, the second network element receives the first QoS control information from the first network element.
[00165] [00165] In some examples, the first QoS control information can be loaded into a first section management message, and the first section management message can be used to instruct to modify or establish information about QoS control on the first network of the terminal device.
[00166] [00166] For example, the first section management message can include a plurality of types. For example, the first section management message can include any of the following: a session establishment message (session establishment) and a section change message (section change). Alternatively, the first section management message can be a message based on a service-oriented interface.
[00167] [00167] In this modality of this request, a communication method is provided based on an interaction architecture between the first network and the second network. When a condition indicated by the first indication information is supported, the first network section of the first section can be established while the second network section of the first section is established. Therefore, the establishment of the first network section of the first section can be determined based on the current condition, thereby avoiding the establishment of an unnecessary section of the first network, and improving communication efficiency.
[00168] [00168] —Optionally, before step 401, method 400 still includes step 404.
[00169] [00169] Step 404. The terminal device sends second indication information to the second network element; correspondingly, the second network element receives the second indication information, where the second indication information is used to indicate that the current condition supports the establishment of the first network section for a terminal device.
[00170] [00170] Before step 401, the second network element can determine the first indication information in at least two modes. For example, in a first mode, the second network element can receive the second indication information from the terminal device, and can determine the first indication information based on the second indication information. For example, if the second network element determines, based on the second indication information, that a current network condition indicates that the section of the first network is established for the terminal device, the second network element can send the first indication information for the first network element, to indicate that the current condition supports the establishment of the first network section for the terminal device.
[00171] [00171] The second indication information may include the first information. In addition, the second indication information may also include the second information. For example, the terminal device can obtain the fifth information from the second network element in a process in which the terminal device registers with a network, where the fifth information is used to indicate that the communications interface exists between the management entity second network mobility entity and the first network mobility management entity. In addition, the first information is determined based on the fifth information. In the first mode,
[00172] [00172] In a second mode, the second network element can generate the first indication information. For example, the second network element can obtain the fifth information, determine the first information based on the fifth information, and generate the first indication information. In addition, the terminal device can send the second information to the second network element, so that the second network element adds the second information to the first indication information. In the second way, the first information is usually explicit.
[00173] [00173] For example, the second network element can be an AMF. Therefore, the second network element is the mobility management entity of the second network, and the second network element can determine that the communications interface exists between the mobility management entity of the second network and the entity. mobility management capability of the first network. Therefore, when there is a communications interface, the second network element can generate the first indication information.
[00174] [00174] —Optionally, after step 403, after obtaining the first QoS control information, the second network element can send the first QoS control information to a base station; after receiving the first QoS control information, the base station can send the first QoS control information to the terminal device. In this case, method 400 still includes step 405.
[00175] [00175] Step405.The second network element sends the first QoS control information to the terminal device using the base station; correspondingly, the terminal device receives the first QoS control information from the first section of the terminal device. The first section is a section established by the terminal device using the second network.
[00176] [00176] The first QoS control information can be used to control the quality of service of a service transmitted on the first network. In other words, the first QoS control information can be control information related to the quality of service of a service transmitted on the first network. For example, the first QoS control information can include at least one of the following: a QoS parameter, a QoS parameter identifier, a packet filter, and packet filter priority information.
[00177] [00177] —Optionally, in step 405, the first QoS control information can be loaded into a second section management message, and the second section management message is used to instruct to modify or establish information control system on the first network of the terminal device.
[00178] [00178] The second section management message can include a plurality of types. For example, the second section management message may include at least one of the following: a section establishment accept message (PDU), an access point specific resource configuration message (AN-specific) resource setup), and a section modification message (section modification). In addition, the message above may be a service acquisition interaction from a service oriented interface.
[00179] [00179] The following describes specific examples of the communication method in this modality of this order with reference to Figure 5A through Figure 8. Figure 5A through Figure 6B show a communication procedure in a section establishment process. Figure 7 shows a communication procedure in a section modification process. Figure 8 shows a communication procedure
[00180] [00180] Referring to Figure 5A and Figure 5B below, the method in Figure 5A and Figure 5B can be applied to architectures 100 to 300. Figure 5A and Figure 5B show a process in which the first indication information is determined based on the second referral information. The method in Figure 5A and Figure 5B includes the following steps.
[00181] [00181] S501. The terminal device obtains fifth information in a process in which the terminal device registers with a network, where the fifth information is used to indicate that a communications interface exists between a mobility management entity on a second network and a security entity. mobility management of a first network.
[00182] [00182] For example, the fifth information may indicate that an AMF supports an N26 interface (that is, an exchange of messages can be performed between the AMF and an MME) or that the AMF supports interacting with 4G.
[00183] [00183] S502. The terminal device sends a first request to establish a PDU section to the AMF, where the first request to establish a PDU section is used to request to establish a first section of the terminal device in a 5G system. The first request to establish a PDU section includes the second referral information.
[00184] [00184] For specific descriptions of the second referral information, refer to the relative content in Figure 4. For example, the second referral information may include first information, and the first information is used to indicate that the AMF supports an N26 interface or that AMF supports interacting with 4G.
[00185] [00185] For example, in an implicit indication mode, the first information can be a standard EPS carrier identifier of the terminal device. For example, when the terminal device determines to initiate a section request for a network, if the AMF supports an N26 interface, the terminal device can determine to allocate the standard EPS carrier identifier.
[00186] [00186] In an explicit indication mode, the first information can be used to directly indicate that an N26 interface exists between the AMF and an MME in an EPS system.
[00187] [00187] The first information can be determined based on the fifth information in S501.
[00188] [00188] In addition, the second indication information may also include second information, and the second information is used to indicate that the current condition is that the terminal device is in a single registration state.
[00189] [00189] In addition, a condition to determine that an EPS section needs to be established may also include: A way of a first section of the terminal device is to maintain continuity, or a DNN indicates a voice network or another network that needs to ensure - section tinnitus.
[00190] [00190] In addition, a message requesting the establishment of a PDU section includes a DNN. If the terminal device stores an EPS APN that corresponds to the DNN, optionally, the first
[00191] [00191] - Optionally, the MFA can obtain a UE-AMBR subscribed from a user EPS network.
[00192] [00192] —Optionally, the AMF can perform SMF selection based on the request to establish a PDU section received from the terminal device.
[00193] [00193] S503. The AMF sends a second PDU section establishment request to an SMF + PGW-C based on the first PDU section establishment request, where the second PDU section establishment request message includes first indication information.
[00194] [00194] - Optionally, the MFA can determine the second indication information as the first indication information.
[00195] [00195] —Optionally, the second PDU section establishment request is generated based on the first PDU section request.
[00196] [00196] The first PDU section request can be loaded into a second establishment request message section.
[00197] [00197] —Optionally, the first indication information may also include the EPS APN.
[00198] [00198] S504. SMF + PGW-C sends a request to obtain subscription data to a UDM + HSS, where the request to obtain subscription data includes fourth information, and the fourth information is used to request to provide subscription data for the first network .
[00199] [00199] For specific descriptions of the fourth information, refer to the relative content in the examples in Figure 4.
[00200] [00200] For example, after the SMF + PGW-C receives the PDU section establishment request message, if it is detected that the PDU section establishment request message includes the first indication information, the SMF + PGW-C can add the fourth information to the request for obtaining subscription data sent to an UDM + HSS.
[00201] [00201] The fourth information may include DNN / APN information, to indicate that UDM + HSS provides both 5G subscription data and EPS subscription data. The DNN / APN is used to indicate that the subscription data for a corresponding DNN / APN is obtained.
[00202] [00202] S505. UDM + HSS sends a subscription data response message to SMF + PGW-C. The subscription data response message includes second QoS control information.
[00203] [00203] For specific descriptions of the subscription data response message and the second QoS control information, refer to the relative content in Figure 4.
[00204] [00204] For example, the second QoS control information may include EPS subscription data from the terminal device. EPS subscription data is subscription data for a specific APN that corresponds to a DNN, which includes an EPS subscribed QoS text and a subscribed APN-AMBR. For example, EPS subscribed QoS text may include: a QoS class identifier (QCI), and an Allocation and Retention Priority, ARP.

[00208] [00208] The first QoS control information is determined based on the second QoS control information. To be the specific content of the first QoS control information, refer to the relative content in Figure 4. Details are not described here again.
[00209] [00209] For example, if a dynamic CCP architecture is deployed on a network, the PDU section establishment response may include an authorized standard CCP rule. The authorized standard PCC rule includes an authorized standard 5G QoS rule and standard EPS carrier information. The first subscribed QoS control information may include the standard EPS carrier information.
[00210] [00210] In addition, in step S507, the PCF + PCRF determines that a section of the EPS system needs to be established for the terminal device. The determination can be based on received referral information sent by SMF + PGW-C.

[00219] [00219] For example, the first QoS control information may include the standard EPS carrier QoS parameter. Still, the first QoS control information may still have a corresponding EPS carrier ID.
[00220] [00220] The first PDU section request message is a PDU section request message from an N2 interface. The N2 interface is a communications interface between AMF and RAN 5G.
[00221] [00221] S512. Optionally, the AN sends an AN-specific resource establishment message to the terminal device, where the AN-specific resource establishment message includes the first QoS control information.
[00222] [00222] For example, an air interface resource establishment procedure can be performed between the AN and the terminal device, and the first QoS control information is loaded into the procedure.
[00223] [00223] S513. The terminal device performs uplink and downlink data transmission with a network device.
[00224] [00224] In the example in Figure 5A and Figure 5B, the AMF determines and sends the first indication information based on the second indication information sent by the terminal device, so that a network side determines, based on the first indication information , generate the EPS system section. The EPS system section does not need to be established at any time, and a pre-establishment procedure is only sent under a specific condition. In this mode, system excesses are reduced as much as possible. This reduces unnecessary excesses caused when the EPS system section establishment is started at any time.
[00225] [00225] —Referring to Figure 6A and Figure 6B below, the method in Figure 6A and Figure 6B can be applied to architectures 100 to 300. Figure 6A and Figure 6B show a process in which the first indication information is generated by an MFA. The method in Figure 6A and Figure 6B includes the following steps.
[00226] [00226] S601. The terminal device sends a first request to establish a PDU section to the AMF, where the first request to establish a PDU section is used to request to establish a first section of the terminal device in a 5G system.
[00227] [00227] For example, the terminal device determines that a section needs to be established, and the terminal device sends the first request for establishment of a PDU section to the AMF.
[00228] [00228] S602. The AMF sends a second PDU section establishment request to an SMF + PGW-C selected based on the first PDU section establishment request, where the second PDU section establishment request message includes first referral information.
[00229] [00229] —Optionally, the second request to establish a PDU section is generated based on the first request to establish a PDU section.
[00230] [00230] Optionally, the AMF generates the first indication information, and adds the first indication information to the second request to establish a PDU section.
[00231] [00231] For example, the first indication information may include first information, and the first information is used to indicate that AMF supports N26 interface information or that AMF supports interacting with 4G.
[00232] [00232] For example, in an implicit indication mode, the first information can be a standard EPS carrier identifier of the terminal device. For example, when the terminal device determines to initiate a section request for a network, if the AMF supports an N26 interface, the terminal device can determine to allocate the standard EPS carrier identifier.
[00233] [00233] In an explicit indication mode, the first information can be used to directly indicate that an N26 interface exists between the AMF and an MME in an EPS system.
[00234] [00234] For example, the MFA can determine the first information, that is, capacity information from the N26 interface. Therefore, the MFA can generate the first referral information based on the first information, and the first referral information including the first information. In addition, the AMF can receive second information from the terminal device, that is, information that indicates that the terminal device is in a unique registration state. Therefore, the AMF can add the second information to the first indication information. Alternatively, optionally, the AMF determines, based on an AMF's ability to support the N26 interface and depending on whether the terminal device is in the single record state, that the indication information is included. Referral information is used to indicate that a section management function establishes a section of the EPS network, for example, EPS carrier information, and includes information such as a QoS parameter.
[00235] [00235] S603. SMF + PGW-C sends a request to obtain subscription data to a UDM + HSS, where the request to obtain subscription data includes fourth information, and the fourth information is used to request to provide subscription data for the first network .
[00236] [00236] For specific descriptions of the fourth information, refer to the relative content in the examples in Figure 4.
[00237] [00237] For example, after the SMF + PGW-C receives the PDU section establishment request message, if the PDU section establishment request message is found to include the first referral information, the SMF + PGW-C can add the fourth information to the request for obtaining subscription data sent to an UDM + HSS.
[00238] [00238] The fourth information may include DNN / APN information, to indicate that UDM + HSS provides both 5G subscription data and EPS subscription data. The DNN / APN is used to indicate that the subscription data for a corresponding DNN / APN is obtained.
[00239] [00239] S604. UDM + HSS sends a subscription data response message to SMF + PGW-C. The subscription data response message includes second QoS control information.
[00240] [00240] For specific descriptions of the subscription data response message and the second QoS control information, refer to the relative content in Figure 4.
[00241] [00241] For example, the second QoS control information may include EPS subscription data from the terminal device. EPS subscription data is subscription data for a specific APN that corresponds to a DNN, which includes an EPS subscribed QoS text and a subscribed APN-AMBR. For example, EPS subscribed QoS text can include: a QoS class identifier r (QoS class identifier, QCI), and an allocation and retention priority
[00242] [00242] S605. SMF + PGW-C sends a third request to establish a PDU section for a PCF + PCRF. The third PDU section request includes the second QoS control information.
[00243] [00243] —Optionally, SMF + PGW-C can perform PCF selection. After selecting the PCF, the SMF + PGW-C sends a request to establish a PDU section to the POCF + PCRF.
[00244] [00244] - S606. PCF + PCRF sends a third PDU section establishment response to SMF + PGW-C, where the third PDU section establishment response corresponds to the third PDU section request, and the third PDU section establishment response.

[00245] [00245] The first QoS control information is determined based on the second QoS control information. For a specific content of the first QoS control information, refer to the relative content in Figure 4. Details are not described here again .
[00246] [00246] For example, if a dynamic CCP architecture is deployed on a network, the PDU section establishment response may include an authorized standard CCP rule. The authorized standard PCC rule includes an authorized standard 5G QoS rule and standard EPS carrier information. The first subscribed QoS control information may include the standard EPS carrier information.
[00247] [00247] In addition, in step S507, the PCF + PCRF determines that a section of the EPS system needs to be established for the terminal device. The determination can be based on received referral information sent by SMF + PGW-C.
[00248] [00248] - “Optionally, a second QoS control parameter can include a standard EPS carrier QoS parameter. The SMF + PGW-C can allocate a 5G QoS flow ID, and correspondingly store the 5G QoS flow ID and a corresponding QoS flow parameter. In addition, the SMF + PGW-C can store corresponding standard EPS carrier information. Standard EPS carrier information can include a standard EPS carrier ID and a standard EPS QoS rule. Standard EPS carrier information and a standard 5G QoS stream can be stored accordingly. Standard EPS carrier information includes a standard EPS carrier QoS parameter that is obtained by UDM + HSS SMF + PGW-C based on a local policy or is a standard EPS carrier QoS parameter that is obtained by SMF + PGW-C from PCF + PCRF.
[00249] [00249] S607. SMF + PGW-C sends a fourth section establishment request message to an UPF + PGW-U.
[00250] [00250] The fourth section establishment request message is a section establishment request from an N4 interface. The N4 interface is a communications interface between UPF + PGW-U and SMF + PGW-C.
[00251] [00251] S608. UPF + PGW sends a fourth section establishment response message to SMF + PGW-C.
[00252] [00252] The fourth section establishment response is a section establishment response message from an NA interface.
[00253] [00253] S609. The SMF + PGW-C sends a section management request determination message to the AMF, where the section management request determination message includes a second PDU section establishment response message and the second establishment reply message
[00254] [00254] The first QoS control information may include, for example, the standard EPS carrier QoS parameter. In addition, the first QoS control information includes a corresponding EPS carrier ID. Optionally, the QoS control information can also include TFT information.
[00255] [00255] S610. The AMF sends a first PDU section request response message to an AN 5G. The first PDU section request response message includes the first QoS control information.
[00256] [00256] For example, the first QoS control information may include the standard EPS carrier QoS parameter. Still, the first QoS control information may still have a corresponding EPS carrier ID.
[00257] [00257] The first PDU section request message is a PDU section request message from an N2 interface.
[00258] [00258] - “Optionally, S610 also includes: allocating, by the terminal device, a standard EPS carrier identifier.
[00259] [00259] —S611. Optionally, the AN sends an AN-specific resource establishment message to the terminal device, where the AN-specific resource establishment message includes the first QoS control information.
[00260] [00260] For example, a procedure for establishing an air interface resource can be performed between the AN and the terminal device, and the first QoS control information is loaded into the procedure.
[00261] [00261] S612. The terminal device performs uplink and downlink transmission with a network device.
[00262] [00262] In this modality of this request, the AMF automatically generates the first indication information, so that a network side determines, based on the first indication information, to generate the EPS system section. The EPS system section does not need to be established at any time, and a pre-establishment procedure is only sent under a specific condition. In this mode, system excesses are reduced as much as possible. This reduces unnecessary excesses caused when the establishment is started at any time.
[00263] [00263] Referring to Figure 7 below, the method in Figure 7 can be applied to architectures 100 to 300. Figure 7 shows a modification communication procedure section. S701, S702, and S703 are three parallel steps. During execution, any of S701, S702, and S703 can be executed. In Figure 7, the first QoS control information can include information about an established or modified EPS carrier. The method in Figure 7 includes the following steps.
[00264] [00264] S701. A terminal device sends a request to modify the PDU section to an AMF. In addition, after receiving the PDU modification request, AMF sends the PDU section modification request to an SMF + PGW-C. The PDU section change request is used to instruct to modify a 5G QoS parameter and instruct to modify an EPS section carrier parameter.
[00265] [00265] For example, when the terminal device determines that an existing PDU session needs to be modified, the terminal device sends a PDU section change request to the AMF and the AMF sends the PDU section change request for SMF + PGW-C. The terminal device can modify an existing QoS resource or delete an established QoS resource or delete a service over a QoS resource by following the procedure.
[00266] [00266] S702. An AF sends a section establishment request to a PCF + PCRF, and establishes an EPS section carrier.
[00267] [00267] The section establishment request is a section establishment request for an N5 interface. The N5 interface is a communications interface between the AF and the POCF + PCRF.
[00268] [00268] For example, AF can actively request a network to establish a resource for a service. When necessary, AF initiates an N5 section establishment procedure for PCF + PCRF to provide service information and a service QoS requirement. When receiving an N5 section request, PCF + PCRF determines, based on an indication sent by a previous SMF request service, that an EPS QoS rule is established when a 5G QoS rule is determined, and sends for SMF + PGW-C a PDU-CAN modification request that includes the 5G QoS rule and the determined EPS QoS rule.
[00269] [00269] S703. The SMF + PGW-C determines that a QoS parameter of a 5G QoS stream needs to be modified, and determines that a QoS parameter of an EPS carrier needs to be modified.
[00270] [00270] For example, SMF + PGW-C determines, based on a local policy, to modify the QoS parameter of the 5G QoS flow, and determines, based on the first indication information received in an establishment process section, modify the EPS carrier QoS parameter.
[00271] [00271] S704. A PDU section modification procedure is performed between the SMF + PGW-C and the PCF + PCRF.
[00272] [00272] The PDU section modification procedure is similar to a PDU section establishment procedure. For the procedure for modifying the PDU section, refer to the relative content of S506 to S507 in Figure 5A and Figure 58 and S605 to S606 in Figure 6A and Figure 6B.
[00273] [00273] S705. The SMF + PGW-C stores or updates the QoS parameter of the EPS carrier.
[00274] [00274] For example, if a section modification procedure initiated by the terminal device and a network side is used to modify a parameter of an existing 5G QoS flow, the SMF + PGW-C stores a new QoS flow parameter Updated 5G, and stores a QoS parameter of a corresponding EPS carrier. If the terminal device and a network create a new 5G QoS stream when initiating a section modification, the network determines to establish a dedicated EPS carrier, and the SMF + PGW-C correspondingly stores the dedicated EPS carrier established when storing the new 5G QoS information.
[00275] [00275] S706. The SMF + PGW-C sends a PDU section change request to the AMF, where the PDU section change request includes information about an established or modified EPS carrier.
[00276] [00276] For example, SMF + PGW-C sends a section management request to the AMF, where the section management request includes a PDU section modification request, and the PDU section modification request. PDU section includes information about the established or modified EPS carrier.
[00277] [00277] S707.The AMF sends a PDU section request to an (R) AN, where the PDU section request includes information about the established or modified EPS carrier.
[00278] [00278] The PDU section request in S707 is a PDU section request from an N2 interface. The N2 interface is a communications interface between the AMF and an AN.
[00279] [00279] S708. The AN sends an AN-specific resource change message to the terminal device, where the AN-specific resource change message includes information about the established or modified EPS carrier.
[00280] [00280] For example, an AN specific resource modification procedure for AN is established between the terminal apparatus and the AN; in the procedure, the AN sends the information about the established or modified EPS carrier to the terminal device. If the terminal device determines that the information about the established or modified EPS carrier is information about a newly established EPS carrier, the terminal device allocates an EPS carrier identifier for the carrier information.
[00281] [00281] —S709.The AN sends a confirmation message requesting a PDU section to the AMF.
[00282] [00282] The PDU section request confirmation message in S709 is a PDU section request confirmation message from the N2 interface.
[00283] [00283] For example, the AN sends an N2 PDU section request confirmation to the AMF. If the terminal device allocates the EPS carrier identifier, the PDU section request confirmation message can include the EPS carrier identifier.
[00284] [00284] S710.AAMF sends a section right request to SMF + PGW-C.
[00285] [00285] —Optionally, if the terminal device allocates the EPS carrier identifier, the section right request includes the EPS carrier identifier.
[00286] [00286] In this modality of this order, in an existing 5G section modification process, a carrier parameter of an EPS system can be modified according to a re-
[00287] [00287] In the examples in Figure 5A to 7, when the terminal accesses a 5G network and establishes a section or establishes a dedicated QoS flow with the 5G network, the network side can determine, depending on whether the network supports the N26 interface, a terminal device registration mode, and a section mode where to establish an EPS system session. For example, in a section establishment process, when determining, based on fourth information received, to obtain a subscript context for section 5G of a UDM + HSS, SMF obtains a subscript PDN context from the EPS system . The PDN context includes first QoS control information, such as an EPS subcribed QoS profile, and a subscribed access point name aggregate maximum bit rate. rate, subscribed APN-AMBR). The SMF + PGW-C provides an authorized standard 5G QoS rule and authorized standard UPS carrier information for the terminal device. When developing policy and loading control (PCC), the SMF + PGW-C interacts with the PCF to obtain an authorized standard 5G QoS rule and authorized standard EPS carrier information. Otherwise, SMF can execute authorization based on a local policy.
[00288] [00288] Optionally, in a process of establishing a dedicated carrier started in a network or a process of establishing a dedicated carrier started in a terminal device, the PCF / SMF + PGW-C determines the QoS rule of the EPS system found
[00289] [00289] - “Optionally, when a QoS flow is deleted or modified, the network side can synchronously modify or delete the corresponding EPS carrier information.
[00290] [00290] Referring to Figure 8 below, the method in Figure 8 can be applied to architectures 100 to 300. Figure 8 shows a communication procedure in which a terminal device registers with a network, and shows a process in which the terminal device obtains fifth information when registering with the network. The method in Figure 8 includes the following steps.
[00291] [00291] S801.The terminal device sends a registration request to a (R) AN; correspondingly, (R) AN receives the registration request.
[00292] [00292] S802. (R) AN sends the registration request to an MFA.
[00293] [00293] For example, (R) AN can select an AMF, and send the registration request to the selected AMF.
[00294] [00294] S803. The AMF sends a registration acceptance message (register accept) to the terminal device via (R) AN, where the registration acceptance message includes the fifth information.
[00295] [00295] For the specific content of the fifth information, refer to the relative descriptions in Figure 4. For example, the fifth information can be directly used to indicate that a communications interface exists between a mobility management entity of a company. second network and a mobility management entity for a first network. For example, the fifth information is used to indicate that a current network supports an N26 interface between the MFA and an MME.
[00296] [00296] In this modality of this request, the registration acceptance message sent by the AMF to the terminal device carries the fifth information, and the fifth information is used to indicate that the communications interface exists between the entity managing the second network mobility and the first network mobility management entity. Therefore, communication is performed based on the fifth information, thereby improving communication efficiency.
