5.4.11.5 Network selection for NR 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).
Network selection principles specified in clause 5.2.2 apply also for NR satellite access.
For NR satellite access, a UE with location capability should use its awareness of its location to select a PLMN that is allowed to operate in the UE location as specified in TS 23.122 [17].
In order to ensure that the regulatory requirements are met, the network may be configured to enforce this UE choice by verifying the UE location, as described in clause 5.4.11.4.
