Question: In an MBMS Session Start Procedure, what is the primary purpose of the configurable delay (time to MBMS data transfer) after sending the Session Start Request message?
Option 1: To allow for UE authentication before MBMS data transmission
Option 2: To enable the network to perform necessary procedures for MBMS data transfer, avoiding buffering in entities other than the BM-SC
Option 3: To synchronize MBMS sessions across different access networks (2G, 3G, E-UTRAN)
Option 4: To allocate additional bearer resources for potential late-joining UEs
Explanation: The configurable delay is intended to provide sufficient time for the network to complete all required setup procedures before the BM-SC begins transmitting MBMS data, ensuring no buffering occurs in entities other than the BM-SC, optimizing the transmission process.
