Question: In a 5G system supporting remote UE access to emergency sessions via relay UEs, what is the primary action a User Equipment (UE) should take before attempting an emergency session via a relay UE?
Option 1: Immediately attempt an emergency session via a nearby relay UE for faster response.
Option 2: Try to establish a non-emergency call to test network connectivity before the emergency session.
Option 3: First, attempt to make an emergency session via any available cellular or wireless network.
Option 4: Send a location update to the network and then wait for instructions on how to proceed.
Explanation: This is because the primary requirement for handling emergency situations effectively is ensuring the quickest possible connection to emergency services. Directly attempting an emergency call via any available network aligns with this goal, maximizing chances of a swift response from emergency services, regardless of the UE's location or the network's availability for non-emergency services, also respecting local regulatory requirements by prioritizing direct network access for emergencies before resorting to alternative methods like relay UEs.
