Question: In the context of MBMS Session signalling procedure, what additional information may the MME provide to MCEs specifically in a distributed MCE architecture during Session Start or Session Update?
Option 1: Time of MBMS data transfer and time of MBMS data stop
Option 2: Only QoS parameters for enhanced service quality
Option 3: List of UE identities interested in the MBMS session
Option 4: Updated Scheduling Information for concurrent sessions
Explanation: In a distributed MCE architecture, to ensure synchronized data delivery across different MCEs, the MME needs to provide explicit timing information. Thus, during Session Start or Update, the MME may inform the MCEs about the 'time of MBMS data transfer' (start time) and 'time of MBMS data stop' (end time), ensuring all MCEs start and stop data delivery at the same absolute times. This is crucial for maintaining service continuity and coherence across the distributed architecture.
