Question: Which entity typically triggers the M2 Setup procedure in an E-UTRAN to ensure proper interoperation and exchange of MCCH related BCCH content?
Option 1: eNB (Evolved Node B)
Option 2: MCE (Mobility Management Entity's counterpart for MBMS, Multimedia Broadcast Multicast Service)
Option 3: UE (User Equipment)
Option 4: EPC (Evolved Packet Core)
Explanation: The correct answer is Option 1 because the eNB is responsible for initiating procedures that ensure seamless network operation, including setup and configuration exchanges with other network elements like the MCE. Triggering the M2 Setup procedure by the eNB aligns with its role in managing radio resources and ensuring proper interoperation within the E-UTRAN.
