Question: What is a prerequisite for the Multi-Cell/Multicast Coordination Entity (MCE) to perform counting for an MBMS (Multimedia Broadcast Multicast Service) service using the MBMS Service Counting Function within an MBSFN (MBMS Single Frequency Network) area?
Option 1: The UE (User Equipment) must be in idle mode.
Option 2: The eNodeB must have dedicated broadcast resources allocated.
Option 3: The MBMS service must be encrypted.
Option 4: Access to the MBMS service must not have been denied by the admission control function for the corresponding MBMS session.
Explanation: This is correct because, according to the specifications, the MCE can only perform counting for those MBMS services for which access has not been blocked by the admission control function. This ensures that resources are allocated efficiently and that counting is accurate, reflecting only authorized service accesses within the MBSFN area.
