What This Covers
Captures slice selection, allowed NSSAI handling, rejected S-NSSAI scenarios, and slice-aware session establishment procedures.
These procedures are useful when you want a focused view of one 5G signaling family rather than the full 5G library.
Use this category page to jump into the main network slice procedures procedures without scanning the broader 5G call flow library.
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
