Question: Which of the following is NOT a primary procedure for an Application Function (AF) to interact with the 5G Core Network (5GC) for Multimedia Broadcast and Multicast Services (MBS) Management, as per 3GPP specifications?
Option 1: MBS TMGI (Temporary Mobile Group Identity) Management Procedures
Option 2: MBS Session Management Procedures
Option 3: MBS User Service Management Procedures
Option 4: UE (User Equipment) Authentication and Authorization Procedures
Explanation: The correct answer is Option 4 because the provided context specifically outlines four key procedures for MBS management: TMGI management, Session management, User Service management, and User Data Ingest Session management. UE Authentication and Authorization Procedures, while crucial in telecom networks, are not listed among these specific MBS management interactions between an AF and the 5GC, as per the given context. This highlights the importance of distinguishing between general network procedures and those specifically tailored for MBS management in 5G networks.
