Question: In an MBMS (Multimedia Broadcast/Multicast Service) architecture, when does the BM-SC Session and Transmission function typically initiate the MBMS Session Stop procedure in various network types?
Option 1: Immediately after the last MBMS data packet is transmitted.
Option 2: When no more MBMS data is expected for a sufficiently long period, justifying the release of bearer plane resources.
Option 3: Upon receiving a manual termination request from the network operator.
Option 4: Automatically at midnight every day to conserve network resources.
Explanation: Initiating the MBMS Session Stop procedure when no more MBMS data is expected for a sufficiently long period allows for the efficient release of bearer plane resources, optimizing network performance and capacity across different network types.
