Question: What triggers the release of bearer resources in an MBMS (Multimedia Broadcast/Multicast Service) session?
Option 1: When the BM-SC determines a prolonged period without data transmission, justifying resource removal.
Option 2: Immediately after the last user equipment (UE) disconnects from the MBMS session.
Option 3: At the start of each new MBMS session to ensure fresh resource allocation.
Option 4: When the overall network load decreases below a predefined threshold.
Explanation: In the context of MBMS, efficient management of network resources is crucial. The BM-SC's determination that there will be an extended period without data transmission for a session is the trigger for releasing bearer resources, optimizing resource utilization for other services or sessions as needed.
