Question: In a distributed MCE architecture, where the MCE is part of the eNB, what parameter ensures synchronized session control and facilitates resource reallocation for MBSFN operation mode during an MBMS Session Update procedure?
Option 1: MBMS Data Transfer Start (absolute time stamp)
Option 2: Time to MBMS Data Transfer
Option 3: MBMS Session Update Timer
Option 4: MBSFN Area Configuration
Explanation: In a distributed MCE architecture with the MCE integrated into the eNB, synchronized session control and efficient resource management for MBMS over MBSFN operation mode require precise timing. The 'MBMS Data Transfer Start' parameter, providing an absolute time stamp, ensures all nodes are aligned for the start of data transfer, facilitating seamless resource allocation adjustments as needed, crucial for maintaining service quality across the network.
