Lab: Paging failure analysis

When Paging Fails

Paging failures result in delayed or completely failed data delivery to idle subscribers. Common causes include the UE being outside the paged area because the TAI list does not cover its current location, DRX cycle mismatches between the UE and network configuration, paging occasion calculation errors due to incorrect UE identity parameters, the UE being out of radio coverage entirely, and N2 transport issues preventing the AMF from reaching gNBs. Systematic paging failure diagnosis requires checking each of these potential failure points.
