Validating and supplementing emergency call information
First Claim
1. A computer-implemented method comprising:
- receiving a normalized emergency call signal derived from an original emergency call that was routed from a carrier network to a Public Safety Answering Point (PSAP);
identifying a probable origination location of the original emergency call from features of the normalized emergency call signal;
accessing one or more additional normalized signals within a specified distance of the probable origination location;
validating the probable origination location, from features of the one or more additional signals, to establish a validated origination location;
detecting an event from the features of normalized emergency call signal based on the validated origination location, the event including the validated origination location and a probability that the event is true; and
sending the event to the PSAP notifying the PSAP of additional data related to the original emergency call.

Abstract
The present invention extends to methods, systems, and computer program products for validating and supplementing emergency call information. A Public Safety Answering Point receives an emergency (e.g., 911) call from a mobile device. Parts of the emergency call are processed to identify an emergency call location. Characteristics of the emergency call are combined with characteristics of other signals to identify and emergency call event, including the emergency call location. The emergency call event is sent to the Public Safety Answering Point. Prior to receiving phase II data and possibly even prior to receiving phase I data, the Public Safety Answering Point receives the event. The Public Safety Answering Point tailors dispatch of emergency resources responding to the emergency call based on characteristics of the event, including the originating location.
