Question: When an MBMS capable UE receives an MCCH information change notification, what action does it take regarding the usage of MCCH information?
Option 1: Immediately stop using the previous MCCH information and wait for the new one.
Option 2: Start using the new MCCH information from the moment the notification is received.
Option 3: Ignore the notification if already receiving an MBMS service.
Option 4: Continue using the previously received MCCH information until the new MCCH information has been acquired.
Explanation: This is because, according to handling procedures for MCCH information change notifications, the UE continues to utilize the existing MCCH information setup until it successfully acquires and can switch to the updated configuration, ensuring seamless service continuity without interruptions during the transition period.
