Question: In a Mission Critical (MC) service scenario, how do MC clients on non-3GPP devices receive traffic over an MBMS (Multimedia Broadcast Multicast Services) bearer?
Option 1: Directly from the MC Service Server via unicast transmission
Option 2: Via an MC Gateway UE, which forwards the traffic received over the MBMS bearer
Option 3: Through a dedicated point-to-point connection established by the non-3GPP device with the cellular network
Option 4: By using a third-party relay server not specified in the MC service architecture
Explanation: In Mission Critical services, non-3GPP devices rely on an intermediary for broadcast/multicast traffic. The MC Gateway UE forwards relevant MBMS traffic to MC clients after receiving instructions, enabling participation in mission-critical communications without direct 3GPP connectivity for MBMS services.
