5G Data Path Management
5G user-plane call flows show how traffic paths are activated, routed, modified, and recovered across UPF and mobility events. Use this hub to jump into data path setup, UPF routing, path modification, mobility path recovery, and idle or inactive reactivation flows.

What This Covers
User-plane procedures activate and restore the data path used by active PDU sessions.
UPF routing, path modification, mobility recovery, and reactivation flows show where traffic handling changes after state or location changes.
Use the links below to jump directly into path activation, mobility continuity, service request, and idle or inactive return call flows.
Path Activation and Return to Service
Procedures that restore or reactivate user-plane availability after idle or inactive return.
- Session Reactivation after Idle/Inactive Return — Resume data path after service return
Mobility-Driven Path Continuity
Procedures that preserve or recover the data path after mobility or path-switch events.
- Session Recovery after Mobility / Path Switch — Restore user-plane continuity after mobility
