LTE Paging, Idle, and Recovery Procedures
This hub groups the LTE procedures that operate after the UE is already registered but idle, paged, or recovering service.

What This Covers
This category covers LTE procedures that return the UE from idle reachability into active signaling and service.
Common nodes are the UE, eNB, and MME.
These procedures matter because paging and service recovery are common break points in live networks.
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.
