Question: When does a User Equipment (UE) apply the Multimedia Broadcast Multicast Service (MBMS) Control Channel (MCCH) information acquisition procedure to receive MBMS services in an Evolved Universal Terrestrial Radio Access Network (E-UTRA)?
Option 1: Only when initially subscribing to an MBMS service
Option 2: Periodically, every hour, while within the MBSFN area
Option 3: Upon entering the corresponding MBSFN area (e.g., after power-on, following UE mobility) and upon notification of MCCH information change
Option 4: Daily, at a predefined time, to update MBMS service listings
Explanation: This is because the UE needs to acquire the latest MCCH information to ensure seamless reception of MBMS services whenever it enters a new MBSFN area (which could be after powering on or moving) and when notified of changes to the MCCH information, as per standard RRC protocol specifications for efficient resource utilization and service continuity.
