Wireless local area network emergency call location update

A system for handling a voice over Internet protocol (VOIP) emergency call, the system comprising:

• a telephony provider system, comprising a VoIP call engine and an emergency call router system, the telephony provider system configured to:
• receive a VoIP emergency call made to a designated emergency phone number from a user equipment (UE) via a wireless local area network (WLAN);
• during the VoIP emergency call, obtain location data from a presence information data format location object (PIDF-LO) tag;
• compare the location data from the PIDF-LO tag with a registered location mapped to the UE, wherein the registered location is intended to correspond to an address at which the WLAN is installed;
• determine that the location data indicates a location more than a threshold distance away from the registered location;
• and
• cause a registered location update request to be transmitted to the UE based on determining that the location data indicates the location is more than the threshold distance away from the registered location, wherein the registered location update requests an update to the stored registered location.

A non-transitory processor-readable medium, comprising processor-readable instructions configured to cause one or more processors to:

• receive a VoIP emergency call made to a designated emergency phone number from a user equipment (UE) via a wireless local area network (WLAN);
• during the VoIP emergency call, obtain location data from a presence information data format location object (PIDF-LO) tag;
• compare the location data from the PIDF-LO tag with a registered location mapped to the UE, wherein the registered location is intended to correspond to an address at which the WLAN is installed;
• determine that the location data indicates a location more than a threshold distance away from the registered location;
• and
• cause a registered location update request to be transmitted to the UE based on determining that the location data indicates the location is more than the threshold distance away from the registered location, wherein the registered location update requests an update to the stored registered location.
