Question: What is the primary purpose of the network providing MBMS (Multimedia Broadcast Multicast Service) bearer event notifications to the MC (Mission Critical) service server, an instantiation of a GCS (Group Communication Service) AS (Application Server)?
Option 1: To inform the MC service server about the network's ability to deliver the service, enabling it to track MBMS bearer status.
Option 2: To request additional resources for MBMS bearers from the MC service server in case of network overload.
Option 3: To initiate MBMS bearer suspension/resume directly from the MC service server without RAN involvement.
Option 4: To provide the MC service server with a list of all available MBMS services for user selection.
Explanation: The correct answer, Option 1, highlights the key reason for MBMS bearer event notifications: to keep the MC service server informed about the network's capability to deliver the service by providing updates on the MBMS bearer status. This includes start results, allocation failures in specific cells, current status, and changes due to suspension, resumption, or overload scenarios, ensuring the MC service server has a real-time understanding of service delivery capabilities.
