LTE Paging, Idle, and Recovery Procedures
LTE paging, idle, and recovery procedures show how a registered UE is reached, released, moved in idle mode, and restored after radio or mobility interruption. Use this hub to jump into paging, idle return, cell reselection, radio link failure recovery, RRC re-establishment, NAS recovery, and handover failure recovery call flows.

What This Covers
LTE paging and idle procedures control how a registered UE is reached and moved between idle and connected behavior.
Recovery procedures handle radio link failure, interrupted mobility, and NAS continuation after service breaks.
Use the links below to jump directly into paging, release to idle, cell reselection, RRC re-establishment, NAS recovery, and handover failure recovery call flows.
Idle Reachability
Procedures that wake the UE from idle and restore active signaling.
- LTE Paging Procedure — Paging context and idle-mode return behavior.
- LTE Connection Release to Idle — Returns the UE from connected mode to idle behavior.
Radio Failure Recovery
Procedures that recover radio control after interruption or failure.
- LTE Radio Link Failure and Recovery — Explains radio failure and the resulting recovery options.
- LTE RRC Re-establishment Procedure — Restores radio signaling after certain failure cases.
Release and Return to Idle
Procedures that release the connected path and return the UE to idle behavior.
- LTE RRC Connection Release Procedure — Releases the connected signaling context.
- LTE Cell Reselection Procedure — Idle mobility path after release or idle return.
Service Recovery
Procedures that help the UE continue service after interruption or failed mobility.
- LTE NAS Recovery After Radio Failure — NAS-side recovery path after radio interruption.
- LTE Handover Failure and Recovery — Recovery path after interrupted mobility continuation.
