Abstract
Various arrangements for handling a voice over Internet protocol (VoIP) emergency call are provided herein. A VoIP emergency call can be made to a designated emergency phone number from a user equipment (UE). During the VoIP emergency call, location data can be obtained from a presence information data format location object (PIDF-LO) tag. The location data from the PIDF-LO tag can be compared with a registered location mapped to the UE. If determined that the location data indicates a location more than a threshold distance away from the registered location, a registered location update request can be transmitted to the UE.
