5G Network Slice Procedures
5G network slicing procedures show how the network selects, authorizes, rejects, and maintains slice context across registration, session setup, and mobility. Use this hub to jump into network slice selection, allowed NSSAI handling, rejected S-NSSAI behavior, slice-aware registration retry, slice authentication, slice-aware PDU session establishment, and slice mobility call flows.

What This Covers
Slice selection and registration flows decide which S-NSSAIs are allowed, rejected, or require additional handling.
Slice authentication, PDU session setup, and mobility procedures show how slice context affects service admission and continuity.
Use the links below to jump directly into NSSAI, rejected S-NSSAI, slice authentication, slice-aware PDU session, and mobility call flows.
Slice Selection and Registration
Procedures that decide which slices the UE may use during registration and service onboarding.
- Network Slice Selection — UE selects slice
- Slice-Aware Registration Rejection / Retry — Registration retry path when NSSAI or slice admission fails
- Slice Authentication — Authorization for slice
Slice-Aware Session Handling
Procedures where slice authorization or slice context changes how sessions are admitted and maintained.
- Slice-Aware PDU Session Establishment — Session setup path influenced by slice authorization
- Slice Mobility Procedure — Mobility across slices
