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 carrier network;

receiving phase I data from the carrier network corresponding to the emergency call at an application;

requesting phase II data from the carrier network corresponding to the emergency call;

prior to receiving phase II data from the carrier network, receiving at a display separate from the application, a detected event derived from (1) a signal source indicating a data provider of a raw signal used to detect the detected event and (2) a signal type indicating a media or format type of the raw signal used to detect the detected event, the detected event including;

an event location associated with the emergency call; and

a prior calculated probability determination, based at least on the signal type, that the detected event is true; and

tailoring dispatch of emergency resources responding to the emergency call based on the event location and the prior calculated probability determination.

2. The method of claim 1, wherein receiving the detected event comprises receiving an electronic 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 with the mobile device; and

receiving a synthesized voice audio overlay audibly indicating a mobile device location via the audio channel; and

wherein tailoring dispatch of emergency resources comprises tailoring dispatch of emergency resources based on the mobile device location.

5. The method of claim 1, wherein receiving the detected event comprises receiving the event location and the prior calculated probability determination prior to receiving the phase I data.

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

and

wherein tailoring dispatch of emergency resources responding to the emergency call comprises referring the emergency call to another PSAP responsible for emergency response at the call originating location.

7. The method of claim 1, wherein receiving the detected event comprises receiving an event categorized as one or more of:

a fire, a shooting, an active shooter, a traffic accident, a natural disaster, or a protest.

8. The method of claim 1, wherein receiving the detected event comprises receiving a severity indicating how severe the event is.

9. The method of claim 1, wherein receiving the detected event comprises receiving content associated with the emergency call.

10. The method of claim 1, wherein receiving the detected event comprises receiving a time associated with the event.

14. The system of claim 1, further comprising instructions configured to:

establish an audio channel with the mobile device; and

receive a synthesized voice audio overlay audibly indicating a mobile device location via the audio channel; and

wherein instructions configured to tailor dispatch of emergency resources comprise instructions configured to tailor dispatch of emergency resources based on the mobile device location.

20. The method of claim 1, wherein the prior calculated probability determination is calculated from a normalized signal associated with the detected event prior to the detected event being received at the display separate from the application.

11. A 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 carrier network;

receive, from the carrier network, phase I data corresponding to the emergency call at an application;

request phase II data derived by the carrier network corresponding to the emergency call;

prior to receiving phase II data from the carrier network, receive at a display separate from the application a detected event derived from (1) a signal source indicating a data provider of a raw signal used to detect the detected event and (2) a signal type indicating a media or format type of the raw signal used to detect the detected event, the event including;

an event location associated with the emergency call; and

a prior calculated probability determination, based at least on the signal type, that the detected event is true; and

tailor dispatch of emergency resources responding to the emergency call based on the event location and the prior calculated probability determination.

12. The system of claim 11, wherein the instructions configured to receive the detected event comprise instructions configured to receive an electronic message.

13. The system of claim 11, wherein the 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.

15. The system of claim 11, wherein the instructions configured to receive the detected event comprise instructions configured to receive the event location and the prior calculated probability determination prior to receiving the phase I data.

16. The system of claim 11, wherein instructions configured to receive the emergency call comprise instructions configured to receive the emergency call at a Public Safety Answering Point (PSAP);

and

wherein the instructions configured to tailor dispatch of emergency resources responding to the emergency call comprise instructions configured to refer the emergency call to another PSAP responsible for emergency response at the call originating location.

17. The system of claim 11, wherein the instructions configured to receive the detected event comprises instructions configured to receive the detected event categorized as one or more of:

a fire, a shooting, an active shooter, a traffic accident, a natural disaster, or a protest.

18. The system of claim 11, wherein the instructions configured to receive the detected event comprise instructions configured to receive a severity indicating how severe the detected event is.

19. The system of claim 11, wherein the instructions configured to receive the detected event comprise instructions configured to receive a time associated with the event.
