Question: In a Service Enabler Architecture Layer for Verticals (SEAL) setup, what triggers the location management client to send location-related information to the location management server during inter-system switching between LTE and 5G systems?
Option 1: Change in User Equipment (UE) battery level
Option 2: Update in VAL (Vertical Application Layer) data transmission protocol
Option 3: Modification in Network Resource Management (NRM) server configuration
Option 4: Radio Access Technology (RAT) change due to location update
Explanation: During inter-system switching between LTE and 5G systems, the key trigger for sending location-related information is the change in Radio Access Technology (RAT), which occurs when a User Equipment (UE) moves from one system to another, necessitating an update for accurate guidance on receiving VAL data. This RAT change is directly tied to the UE's location update.
