Question: In the context of multicast resource management for EPS, what procedure does the NRM server (performing as GCS AS) use to activate, deactivate, or modify multicast bearers?
Option 1: Dedicated Bearers Setup/Teardown procedures
Option 2: Activate/Deactivate/Modify MBMS Bearer procedures specified in conjunction with Group Communication System Enablers for LTE (GCSE_LTE)
Option 3: General Packet Radio Service (GPRS) Tunnelling Protocol (GTP) Path Management procedures
Option 4: Policy and Charging Control (PCC) Rule Management procedures
Explanation: The correct answer is Option 2 because, in managing multicast resources for EPS, the NRM server uses Activate, Deactivate, and Modify MBMS Bearer procedures tied to Group Communication System Enablers for LTE (GCSE_LTE), while acting as the GCS AS, for efficient group communication management within the EPS framework.
