Step 1: a network side AF (Application Function) triggers a session request message, which may be a request for inquiring UE information or upgrading a UE version, and carries an external user group identifier indicating that a PDU session is required to be created for users in the group.
Step 2: after receiving the session request message, the NEF (Network capability Exposure Function) converts the external user group identifier into an internal user group identifier, and carries the internal user group identifier in a request sent to the PCF (Policy Control Function).
And step 3: after receiving the request, the PCF queries all the user ids from the UDR (Unified Data Repository) according to the internal user group ids.
And 4, step 4: the PCF finds out the corresponding AMF (Access and Mobility Management Function/network Access point) for each user in turn according to the information when the user registers, and initiates a PDU session creation request to the AMF.
And 5: the AMF forwards the request to the UE through a Radio Access Network (RAN), and then the UE triggers the establishment of the session according to the indication.
Step 6/7/8: the UE returns the response message to the AF through RAN, AMF, PCF and NEF.
In this embodiment, in the process of running the application, the AF finds that the application needs to initiate a data service to a group of terminals, for example, real-time query or software upgrade, the AF initiates a session establishment request carrying a group identifier of the group of users, the NEF receives the request of the AF and forwards the request to the PCF, and the PCF queries all users in the group from the UDR according to the group identifier. For each user, PCF finds out the corresponding AMF according to the information reported when the user registers, and initiates session establishment requests to the AMF one by one. After receiving the session establishment request from the PCF, the AMF forwards the request to the UE through the RAN, thereby implementing the session establishment trigger. And after receiving the trigger request, the UE initiates a session establishment request.
