Question: What is a prerequisite for a User Equipment (UE) to access Evolved Packet System (EPS) for Uncrewed Aerial Vehicle (UAV) services?
Option 1: The UE must be registered with the UAV manufacturer.
Option 2: The UE must have an assigned CAA-level UAV ID.
Option 3: The UE must support a specific frequency band.
Option 4: The UE must have a valid International Mobile Subscriber Identity (IMSI).
Explanation: According to the EPS specifications, before accessing EPS for UAS services, the UE supporting UAS services must have an assigned CAA-level UAV ID. This ensures that the UAV can be properly identified and authenticated within the network.
