RELEASE OF EMERGENCY PDN BEARER FOR A VOLTE EMERGENCY CALL WITHOUT EMERGENCY REGISTRATION

Abstract:

Techniques described herein may increase the efficiency of a network by ensuring that bearers, used in anonymous (e.g., emergency) calls are properly deactivated. A user equipment ("UE") may maintain an inactivity timer after an emergency call has ended, and may request that the network deactivate the bearer upon expiration of the inactivity timer, if the bearer is still active upon the expiration of the inactivity timer.
