Question: In a mission-critical service scenario, when a disconnection request is initiated for a non-3GPP device hosting an MC (Mission Critical) client, what is the role of the MC Gateway UE?
Option 1: The MC Gateway UE directly disconnects the non-3GPP device from the network without notifying the MC server.
Option 2: The MC Gateway UE forwards the disconnection request to the corresponding MC server to disconnect the MC gateway UE to MC client connection.
Option 3: The MC Gateway UE sends an acknowledgement to the requesting entity but does not take any further action regarding the disconnection.
Option 4: The MC Gateway UE updates its internal registry to reflect the disconnection request without notifying external elements.
Explanation: In mission-critical service scenarios, especially involving non-3GPP devices with MC clients, maintaining seamless and controlled connectivity is crucial. The MC Gateway UE acts as an intermediary, ensuring that disconnections are properly managed through the MC server. By forwarding the disconnection request to the MC server, the MC Gateway UE adheres to this controlled management principle, unlike the direct or passive actions described in the other options.
