Section: 6.46.3 Service continuity
Content: For a 5G system with satellite access, the following requirements apply: A 5G system with satellite access shall support service continuity between 5G terrestrial access network and 5G satellite access networks owned by the same operator or owned by different operators having an agreement. Subject to regulatory requirements and operator’s policy, a 5G system with satellite access shall support service continuity (with minimum service interruption) for a UE engaged in an active communication, when the UE changes from a direct network connection via 5G terrestrial access to an indirect network connection via a relay UE (using satellite access) and vice-versa. NOTE: It is assumed that the 5G terrestrial access network and the satellite access network belong to the same operator. Subject to regulatory requirements and operator’s policy, a 5G system with satellite access shall be able to support service continuity (with minimum service interruption) of a UE-Satellite-UE communication when the UE communication path moves between serving satellites (due to the movement of the UE and/or the satellites). Subject to regulatory requirements and operator’s policy, a 5G system with satellite access shall support service continuity (with minimum service interruption) of a UE-Satellite-UE communication when the communication path between UEs extends to additional satellites (through ISLs).
