Question: In LTE, what is the primary purpose of MBMS (Multimedia Broadcast Multicast Services) counting for an operator?
Option 1: To optimize Unicast bearer resource allocation for individual UEs.
Option 2: To determine if a sufficient number of interested UEs justify delivering a service via MBSFN (MBMS Single Frequency Network).
Option 3: To monitor and control the quality of service for ongoing MBMS sessions.
Option 4: To manage handovers between different MBSFN areas.
Explanation: The correct answer reflects the core purpose of MBMS counting. It allows operators to decide if using MBSFN for service delivery is justified by user interest, optimizing resource utilization and potentially enhancing the user experience, directly impacting network resource allocation.
