Question: In IOPS group standalone SDS using signalling control plane, how are related group session packets (signalling messages) distributed to discovered MC users associated with the target IOPS MCData group ID?
Option 1: Exclusively over dedicated unicast bearers for each MCData UE.
Option 2: Only via broadcast transmissions to all connected UEs within the IOPS network.
Option 3: Through a combination of D2D (Device-to-Device) communications and cellular networks.
Option 4: Either over MBMS (Multimedia Broadcast Multicast Services) bearers or replicated unicast transmissions, depending on the configuration.
Explanation: This is correct because the IOPS MC connectivity function distributes group session packets in two ways: Over MBMS bearers for efficient multicast distribution, and via replicated unicast transmissions to ensure all associated MCData UEs receive the packets, accommodating different network conditions and user configurations.
