Question: In Mission Critical (MC) services over 5G systems, what triggers the location management client to send location-related information to the location management server during inter-system switching between LTE and 5G?
Option 1: Radio Access Technology (RAT) change
Option 2: MC Service Server Initialization
Option 3: User Equipment (UE) Handover Request
Option 4: MBSF/MBSTF Deployment Update
Explanation: During inter-system switching between LTE and 5G for MC services, the change in Radio Access Technology (RAT) from one system to another (e.g., from 5G to LTE or vice versa) triggers the location management client to update the server. This ensures seamless guidance for receiving MC services post-location update, highlighting RAT change as a critical trigger in this context.
