Question: What is the primary purpose of the GW MC (Mission Critical) service ID in a telecommunications network?
Option 1: To authorize connections for non-3GPP devices accessing an MC system via an MC gateway UE.
Option 2: To authenticate user equipment (UE) for voice over LTE (VoLTE) services.
Option 3: To manage Quality of Service (QoS) for mission-critical data transmissions.
Option 4: To facilitate handovers between 3GPP and non-3GPP access networks.
Explanation: The GW MC service ID is specifically utilized for authorizing connections of non-3GPP devices that are accessing an MC (Mission Critical) system through an MC gateway UE. This highlights its role in ensuring secure and authorized access to mission-critical services for devices not natively part of the 3GPP ecosystem, underscoring its importance in heterogeneous network environments where diverse device types need to interact with critical communication systems.
