Question: What is the primary purpose of the `MBMSInterestIndication` message sent from the User Equipment (UE) to the E-UTRAN in a wireless communication network?
Option 1: To establish a dedicated bearer for voice calls
Option 2: To indicate the UE's interest in receiving or no longer receiving MBMS services via MRB or SC-MRB
Option 3: To report the UE's current location to the E-UTRAN for paging purposes
Option 4: To negotiate the Quality of Service (QoS) parameters for a specific data application
Explanation: The correct answer is Option 2 because the `MBMSInterestIndication` message is specifically designed to inform the E-UTRAN about the UE's interest in receiving or its lack of interest in receiving Multimedia Broadcast Multicast Services (MBMS) via a Multimedia Broadcast Multicast Service Radio Bearer (MRB) or Single-Cell MBMS Radio Bearer (SC-MRB), including services in receive-only mode. This is crucial for efficient resource allocation and service delivery in wireless communication networks.
