Question: What action does a UE (User Equipment) take if all file repair servers in the serverURI list are determined to be non-responsive, according to MBMS (Multimedia Broadcast/Multicast Service) protocols?
Option 1: The UE will periodically retry connecting to the last selected server.
Option 2: The UE may attempt an HTTP GET to retrieve a potentially new instance of the session's Associated Procedure Description.
Option 3: The UE will automatically switch to a different multicast channel for service continuity.
Option 4: The UE will notify the network operator via SMS (Short Message Service) about the unresponsive servers.
Explanation: In the scenario where all listed file repair servers are non-responsive, the UE's specified behavior includes attempting to retrieve an updated Associated Procedure Description. This approach allows for potential updates or changes in server availability to be communicated to the UE, ensuring it can adapt to network conditions.
