- MB-SMF can also know that it is the user's joining operation through the IP message or the information instructing the user to join.
- Step 304 MB-SMF invokes the multicast authorization operation (that is, the first service operation) of MBSF (that is, the first network function), for example, the Nmbsf_MBSession_JoinAuth operation is invoked;
- the foregoing multicast authorization operation carries the user identification and the multicast information in the foregoing step 304, (if the second multicast service information in the foregoing step 303 does not include the location information of the terminal and the RAN node information that the terminal accesses) Contains the RAN node information that the terminal accesses, and may also contain the location information of the terminal.
- Step 305 The MBSF judges the mode of the multicast service (that is, determines the mode selection result);
- MBSF judges the mode of the multicast service based on the number of users joining the multicast service, or whether the terminal’s IP address is received, or the session connection identifier is received, or the QFI is received, or the session option instruction is received. Or whether the RAN node supports multicast, etc.;

- Step 306 MB-SMF (here, the above-mentioned third network function) returns the result of the multicast session operation through the multicast session response, which may be the mode information indicated by the MBSF, that is, if the MBSF returns the mode information to the MB-SMF, then MB-SMF can return mode information to AMF. If MBSF does not return mode information to MB-SMF, MB-SMF does not return mode information to AMF.
- Step 307 The AMF returns the result of the multicast service operation through the multicast service response, which may be the mode information indicated by the MB-SMF. That is, if the MB-SMF returns the mode information to the AMF, the AMF can return the mode information to the SMF. -SMF does not return mode information to AMF, then AMF does not return mode information to SMF, SMF operates according to the mode indication result, such as releasing unnecessary resources in multicast mode or modeless, and establishing forwarding resources in unicast mode.
