Question: What is a requirement for a 5G system with satellite access in terms of roaming?
Option 1: The system must enable roaming of UE supporting both satellite access and terrestrial access between 5G satellite networks and 5G terrestrial networks.
Option 2: The system must only support roaming of UEs that exclusively use satellite access.
Option 3: The system must prioritize roaming to 5G terrestrial networks over 5G satellite networks.
Option 4: The system does not need to support roaming between 5G satellite and terrestrial networks.
Explanation: This option is correct because the requirement states that a 5G system with satellite access must enable roaming of UEs supporting both satellite access and terrestrial access between 5G satellite networks and 5G terrestrial networks. This allows for seamless connectivity and service continuity as users move between different network types.
