Question: In a 5G system with satellite access, what is a requirement for service continuity when a User Equipment (UE) changes its connection from a 5G terrestrial access network to an indirect network connection via a relay UE using satellite access, and vice-versa?
Option 1: Subject to regulatory requirements and operator’s policy, the system shall support service continuity with minimum service interruption.
Option 2: The UE must restart the communication session each time it switches between terrestrial and satellite access.
Option 3: Service continuity is only supported if both the terrestrial and satellite access networks are owned by different operators without an agreement.
Option 4: The UE can only maintain service continuity if it communicates directly with the same serving satellite throughout.
Explanation: This is correct because, as per the service requirements for a 5G system with satellite access, maintaining service continuity with minimal interruption (subject to regulatory and policy constraints) is indeed a specified requirement when switching between terrestrial and satellite connections via a relay UE.
