Abstract:
Systems and methods for providing timely location estimates when a user equipment initiates a call to an emergency number are disclosed. The system enables a user equipment to send the earliest available location that the user equipment can come up with, after detecting an emergency message (e.g., detecting a 911 digit string). This can be done by sending the current location of the user equipment via HTTPS protocol to a telecommunications service provider node (e.g., an end point in GMLC). In this manner, the system avoids a major overhaul of the existing 3GPP E911 location standard while allowing timely compliance of the NG911 mandate.
