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.

Claims

1. A computer-implemented method comprising:

receiving an emergency call from a mobile device via a cellular network;

receiving phase I data corresponding to the emergency call at a legacy application;

requesting phase II data corresponding to the emergency call;

prior to receiving phase II data, receiving an event at a call display separate from the legacy application, the event indicative of an emergency call originating location and including an event category, an event severity, and an event truthfulness, the event severity indicating how severe the event is, the event truthfulness indicating a probability that the event is true; and

tailoring dispatch of emergency resources physically responding to the emergency call based on the emergency call originating location, the event category, the event severity, and the event truthfulness.

2. The method of claim 1, wherein receiving an event comprises receiving a text message.

3. The method of claim 1, wherein tailoring dispatch of emergency resources responding to the emergency call comprises tailoring dispatch of emergency resources responding to a 911 call.

4. The method of claim 1, further comprising establishing an audio channel between the mobile device and a Public Safety Answering Point;

and

wherein receiving an event comprises receiving an audio overlay inserted into the voice channel and audibly indicating the emergency call originating location in a synthesized voice.

5. The method of claim 1, wherein receiving an event comprises receiving the emergency call originating location and additional content prior to receiving the phase I data.

6. The method of claim 1, wherein receiving an emergency call comprises receiving the emergency call at a Public Safety Answering Point;

and

wherein tailoring dispatch of emergency resources responding to the emergency call comprises referring a 911 call to another Public Safety Answering Point responsible for emergency response at the call originating location.

7. The method of claim 1, further comprising:

establishing a voice channel between the mobile device and a Public Safety Answering Point;

transcribing voice communication on the voice channel into text transcription; and

sending the text transcription to signal ingestion modules.

8. A computer system comprising:

a processor;

system memory coupled to the processor and storing instructions configured to cause the processor to;

receive an emergency call from a mobile device via a cellular network;

receive phase I data corresponding to the emergency call at a legacy application;

request phase II data corresponding to the emergency call;

prior to receiving phase II data, receive an event at a call display separate from the legacy application, the event indicative of an emergency call originating location and including an event category, an event severity, and an event truthfulness, the event severity indicating how severe the event is, the event truthfulness indicating a probability that the event is true; and

tailor dispatch of emergency resources physically responding to the emergency call based on the emergency call originating location, the event category, the event severity, and the event truthfulness.

9. The computer system of claim 8, wherein instructions configured to receive an event comprise instructions configured to receiving a text message.

10. The computer system of claim 8, wherein instructions configured to tailor dispatch of emergency resources responding to the emergency call comprise instructions configured to tailor dispatch of emergency resources responding to a 911 call.

11. The computer system of claim 8, further comprising instructions configured to establish an audio channel between the mobile device and a Public Safety Answering Point;

and

wherein instructions configured to receive an event comprise instructions configured to receive an audio overlay inserted into the audio channel and audibly indicating the emergency call originating location in a synthesized voice.

12. The computer system of claim 8, wherein instructions configured to receive an event comprise instructions configured to receive the emergency call originating location and additional content prior to receiving the phase I data.

13. The computer system of claim 8, wherein instructions configured to receive an emergency call comprise instructions configured to receive the emergency call at a Public Safety Answering Point;

and

wherein instructions configured to tailor dispatch of emergency resources responding to the emergency call comprise instructions configured to refer a 911 call to another Public Safety Answering Point responsible for emergency response at the call originating location.

14. The computer system of claim 8, further comprising instructions configured to:

establish a voice channel between the mobile device and a Public Safety Answering Point;

transcribe voice communication on the voice channel into text transcription; and

send the text transcription to signal ingestion modules.
