Question: In the context of Mission Critical (MC) services over a 5G system, what entities are involved when switching between different bearer/session types for MCData service?
Option 1: UE: User Equipment, gNB: Next Generation Node Base, and AMF: Access and Mobility Management Function
Option 2: MBSFN: Multimedia Broadcast Single Frequency Network, SGW: Serving and Packet Data Network Gateway, and PGW: Packet Data Network Gateway
Option 3: MCData Client, RAN: Radio Access Network, and Core Network Entities
Option 4: MCData Client (as the MC service client) and MCData Server (as the MC service server)
Explanation: The correct answer involves understanding the specific roles defined within the Mission Critical Data (MCData) service for bearer/session switching. Here, the 'MCData Client' acts as the 'MC service client', and the 'MCData Server' acts as the 'MC service server'. These entities are directly implicated in the procedure for switching between different types of sessions/bearers for MCData services, highlighting their crucial roles in managing and facilitating these operations within the 5G system's Mission Critical services framework.
