Question: In the E-UTRAN Counting Procedure for MBSFN (Multicast/Broadcast Single Frequency Network), what happens when a UE moves within the same MBSFN area after sending a Counting Response?
Option 1: The UE must retransmit the Counting Response to update its location.
Option 2: The network sends a new Counting Request to confirm the UE's interest.
Option 3: No retransmission of the Counting Response is required from the UE.
Option 4: The UE automatically switches to another MBSFN area.
Explanation: According to the principles of the Counting Procedure, it is specified that "It is unnecessary to retransmit the Counting Response when the UE moves within the same MBSFN area." This indicates that once a UE has responded with its interests in MBMS services within an MBSFN area, moving to a different location within that same area does not necessitate sending another response. This approach helps in minimizing unnecessary signaling overhead within the network.
