Question: What is the primary purpose of the UE using parameters from the BM-SC (Broadcast Multicast Service Centre) to randomize the joining time for an MBMS (Multimedia Broadcast/Multicast Service) session?
Option 1: To ensure seamless handover between different access networks.
Option 2: To prevent network overload by distributing user join times.
Option 3: To enhance the security of multicast transmissions.
Option 4: To prioritize high-priority users over standard subscribers.
Explanation: Randomizing the joining time for MBMS sessions, based on parameters provided by the BM-SC, is crucial to prevent a large number of users from attempting to join simultaneously. This staggered approach mitigates the risk of network overload, ensuring more stable and efficient service delivery. This directly relates to managing network resources and optimizing service accessibility during peak demand periods.
