5G Non-Terrestrial Network (NTN) Procedures
5G NTN procedures show how non-terrestrial access handles registration, mobility, and timing across satellite paths. Use this hub to jump into NTN registration, satellite handover, mobility handling, timing advance, access timing, and large propagation delay call flows.

What This Covers
NTN registration procedures bring the UE into 5G service over non-terrestrial access.
Satellite handover, mobility handling, timing advance, and access timing flows show how NTN manages large propagation delay.
Use the links below to jump directly into NTN registration, mobility, timing advance, access timing, and delay-handling call flows.
NTN Registration and Entry
Procedures that bring the UE into service over non-terrestrial access.
- NTN Registration — Satellite network registration
NTN Mobility and Timing
Procedures that handle large-delay timing behavior and continuity over non-terrestrial paths.
- NTN Handover / Mobility Handling — Satellite mobility and continuity handling
- NTN Timing Advance / Access Timing Handling — Large propagation delay and timing management
