5.4.11.2 Support of RAT types defined in 5GC for satellite access

Taught in 9. Registration, reachability and paging (The 5G system architecture, in depth), 10. Radio, Wi-Fi, cable — every way in (The 5G system architecture, in depth).

In case of NR satellite access, the RAT Types values "NR(LEO)", "NR(MEO)", "NR(GEO)" and "NR(OTHERSAT)" are used in 5GC to distinguish the different NR satellite access types (see clause 5.4.10).

When a UE is accessing to the network via satellite access, the AMF determines the RAT type as specified in clause 5.4.10.

NOTE: The transparent satellite payload and regenerative satellite payload share the same set of RAT type values specified in this clause. If there is a need for differentiating between the payload types, the determination of what kind of payload is based on operator configuration.
