[0230] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0231] For ease of understanding, some contents involved in the embodiments of the present application are described below:

[0232] Currently, the terminal accesses the network through the Non-Access Stratum (NAS) interface, passes through the Access and Mobility Management Function (AMF), the Session Management Function (SMF), and establishes a Protocol Data Unit (PDU) session to transmit relevant data between the terminal and the 5G network. However, many scenarios in the prior art require the UE to interact directly with the core network-related network functions.

[0233] Figure 1 This is one of the schematic diagrams of the interaction between a UE and a core network related network function provided in an embodiment of the present application, such as Figure 1 As shown, Use case 1: In order to understand the data transmission status, such as the jitter delay difference of periodic data arrival, the UE can directly call the jitter value calculated for a specific data stream from the SMF / User Plane Function (UPF) / Policy Control Function (PCF) / Network Exposure Function (NEF), and transmit it to the UE directly through the Application Programming Interface (API) interface call.

[0234] Figure 2 This is a second schematic diagram of the interaction between a UE and a core network related network function provided in an embodiment of the present application, such as Figure 2 As shown, Use case 2: In order to directly customize the quality of service (QoS) guarantee of a specific service, the terminal can directly call the QoS guarantee service of NEF. At this time, compared with the application function (AF) calling the NEF service, the UE can also input the specified QoS indicator, but the indicator should be pre-configured by the UE.

[0235] Figure 3 This is a schematic diagram of the interaction between a UE and a core network related network function provided in an embodiment of the present application.

[0246] In an embodiment of the present application, the above-mentioned communication method is applied to the first network function, and can call the service of the second network function by receiving the first message sent by the terminal and based on the first message, so that the terminal can directly find and call the network service through the first network function, thereby reducing the complexity of the terminal's service search and access, thereby improving the efficiency of the terminal's service search and access.

Optionally, configuration information of the decryption function of the first network function corresponds to configuration information of the encryption function of the terminal;

[0268] The method further comprises:

[0269] When the configuration information of the decryption function is changed, third information is sent to the terminal, where the third information is used to indicate that the configuration information of the decryption function is changed.

[0270] In this implementation, the above-mentioned communication method can send third information to the terminal when the configuration information of the decryption function changes, and the third information is used to indicate that the configuration information of the decryption function has changed, so that the configuration information of the decryption function of the first network function can be consistent with the configuration information of the encryption function of the terminal, which can prevent the first information from being tampered with or unauthorized access during transmission, and ensure smooth communication between the terminal and the first network function, thereby ensuring the integrity of data transmission.

[0278] Specifically, the fifth information may be a request to obtain the network element for which the service needs to be called, that is, the address corresponding to the second network function.

[0279] In this implementation, the above-mentioned communication method can send fifth information to the third network function based on the second information, obtain sixth information of the second network function, the sixth information includes business information corresponding to the second information, and send the sixth information to the terminal, so that the terminal can call the network function service through the third network function, obtain the required business information, etc.

[0283] Receive sixth information sent by the second network function.

[0284] Specifically, the above address information may be information such as an API endpoint address (end-point address) or a Uniform Resource Locator (URL).

[0285] For example, Figure 8 is one of the interactive flow charts of a communication method provided in an embodiment of the present application, such as Figure 8 As shown in the figure, NF registers its own service with NRF. Compared with the existing mechanism, an enhancement is to clarify the slice type, DNN type, optional IP range, and GPSI information that can call the service to authorize the UE proxy that calls the service.

[0286] The UE requests related API service calls, which may include: business information (such as APP ID, etc.), network information indication information required by the UE (such as the demand for computing power, transmission jitter information for its own specific business, latency information, etc.).

[0287] In this implementation, the above-mentioned communication method can receive the seventh information of the third network function in response to the fifth information, the seventh information includes the address information of the second network function, and sends the eighth information to the second network function based on the address information, and receives the sixth information sent by the second network function, so that the terminal can find and discover related services through the third network function.

[0291] Optionally, the second network function is a policy control function PCF, and the sixth information includes user routing policy URSP information of the terminal.

[0292] For example, Fig. 9 This is a second interactive flow chart of a communication method provided in an embodiment of the present application, such as Fig. 9 As shown, the interaction process of the communication method is as follows:

[0293] 1. SMF registers its own functions and service information with NRF. The service information includes event exposure service, which can measure and open the delay, jitter and bandwidth of a specific service flow. Optionally, SMF can register its own event exposure information or information type with NRF;

[0294] 2. After the session is established, the UE will initiate a request for specific information, which will be included in the NAS message. One implementation method is to carry a request message in the NAS data payload, or it can be an HTTP-based API call request (the request can indicate the request jitter delay bandwidth information), and the request includes specific IP quintuple information;

[0295] 3. The UE proxy receives the request message sent by the UE in step 2, parses the request information in the NAS payload, and generates a service call request based on the information. The service query request includes: UE information such as GPSI, IP five-tuple information, and the requested information type; the UE proxy calls the NRF query service and obtains the NRF response, including the target NF ID.

[0296] 4.UE proxy calls the event exposure service of SMF and provides the requested information type, UE information such as GPSI and IP 5-tuple information. SMF feedbacks the delay, jitter and bandwidth information of the flow;

[0297] 5. The UE proxy feeds back the delay, jitter and bandwidth information of the specific flow to the UE, which is also included in the NAS payload.

[0298] In this implementation, the above-mentioned communication method enables the terminal to obtain the delay jitter information of a specific service flow. For downlink data, the UE obtains the delay jitter bandwidth information of a specific service flow in real time, which can make the terminal's experience evaluation of the message more accurate, and can also perform more precise buffer operations and encoding and decoding method selection.

[0299] Optionally, the first information is a session establishment request, and the method further includes:

[0302] Ninth information is sent to the terminal and the radio access network RAN, where the ninth information is used to indicate that establishment of the session is completed.

[0303] For example, Fig.10 This is a third interactive flow chart of a communication method provided in an embodiment of the present application, such as Fig.10 As shown, the interaction process of the communication method is as follows:

[0304] 1. The terminal initiates a session establishment request, using the currently available S-NSSAI, DNN, and FQDN and other optional information;

[0305] 2. After receiving the session establishment request of the FQDN, the UE proxy will optionally go to the PCF to obtain the latest URSPrule information of the network (carrying the terminal GPSI or SUPI information to find the PCF serving the UE);

[0306] 3. The UE proxy accesses the PCF to obtain the URSP information of a specific UE;

[0307] 4. UE proxy selects appropriate S-NSSAI and DNN according to the latest URSP rule information to continue the session establishment process;

[0308] 5. The session establishment is completed and the UE proxy replies to the RAN and the UE.

[0309] In this implementation, the above-mentioned communication method can determine the single network slice selection auxiliary information S-NSSAI and the data network name DNN based on the URSP information, establish a session between the terminal and the session management function SMF based on the S-NSSAI and the DNN, and send ninth information to the terminal and the wireless access network RAN, wherein the ninth information is used to indicate the completion of the establishment of the session, so that the slice can be reselected on the network side through the first network function.
