Question: In a Service Enabler Architecture Layer for Verticals (SEAL), how is location information of a VAL service user typically shared between User Equipment (UE) in an off-network scenario, as per architectural principles?
Option 1: Through direct communication between the VAL clients at the application layer.
Option 2: Via the cellular network's Location Management Function (LMF) for all types of location data.
Option 3: Exclusively using location information retrieved from 3GPP sources.
Option 4: Between the location management clients of respective UEs, based on predefined location reporting configurations.
Explanation: This is correct because, as per the described architecture for off-network scenarios, location information sharing between UEs is facilitated by their respective location management clients. This process is triggered by specific configuration settings for location reporting, allowing for flexibility in the types of location data (including non-3GPP sources) that can be shared. This approach aligns with efficient and direct data exchange principles in a service enabler layer, without necessarily relying on network infrastructure for off-network scenarios.
