Question: Which entity typically initiates the MCE Configuration Update procedure in an Evolved Universal Terrestrial Radio Access Network (E-UTRAN)?
Option 1: eNB (Evolved Node B)
Option 2: UE (User Equipment)
Option 3: MCE (Mobility Management Entity's counterpart for MBMS, Multimedia Broadcast Multicast Service)
Option 4: OSS (Operations Support System)
Explanation: In the context of E-UTRAN, the MCE Configuration Update procedure is designed to update configured data within the MCE and inform the eNB about changes in MCCH related BCCH content. The initiator is logically the MCE, ensuring synchronization with the eNB for efficient multicast/broadcast services, highlighting the MCE's role in managing its configuration for seamless service delivery over E-UTRAN.
