Abstract

The present invention is directed generally to geographic referenced telephone switching. Geospatial (e.g., XY or XYZ) coordinates are created in order to route 911 emergency telephone calls based on the caller'"'"'s location in relation to the proper emergency service provider. Essentially the router gathers and verifies customer user information, matches transmission formats with telephone company provided equipment for 911 Public Safety Answering Points (PSAPs), routes calls based on their existing location, and terminates the phone call in the PSAP with the proper ANI (Automatic Number Identification) and ALI (Automatic Location Information) provided. In addition, due to the capabilities of the geographic referenced system, in certain embodiments, the movement of emergency service needs can be anticipated (or predicted) and PSAPs may be conferenced together so that they can respond as a single unit to someone who may be traveling.

Claims

1. A system for providing emergency call routing, said system comprising:

database for coordinating current physical location of a caller with a geographically sensitive called party; and

a matching circuit for matching an incoming call from a caller currently located at a particular location with a proper called party based upon said geographically sensitive matching data, when said caller has called an emergency calling number.

2. The system of claim 1 wherein said emergency calling number is 911.

3. The system of claim 1 wherein said proper called party comprises a proper Public Safety Answering Point (PSAP).

4. The system of claim 3 wherein said proper PSAP comprises a PSAP that is designated for servicing said caller'"'"'s current physical location.

5. The system of claim 1 further comprising:

routing circuit for routing said caller to said proper called party.

6. The system of claim 1 wherein said matching circuit comprises:

a geospatial coordinate generator for determining a geospatial coordinate for the current physical location of the caller; and

identifying logic for identifying said proper called party to which the caller is to be routed based upon said determined geospatial coordinate.

7. The system of claim 6 wherein said geospatial coordinate generator determines the geospatial coordinate based at least in part on an automatic number identification (ANI) determined for the call.

8. The system of claim 6 further comprising:

formatting logic for formatting information into a format desired for the identified proper called party.

9. The system of claim 8 wherein said information comprises the determined geospatial coordinate.

10. The system of claim 8 wherein said information comprises information pre-stored in said database about said caller.

11. The system of claim 6 wherein said geospatial coordinate comprises an XY coordinate.

12. The system of claim 6 wherein said geospatial coordinate comprises an XYZ coordinate.

13. A method for call routing, said method comprising:

receiving an emergency call from a calling party, said call identified by said calling party dialing a universally known calling number;

determining a present physical location of said calling party, said determining based upon a knowledge of physical coordinates of said calling party; and

completing said emergency call to a service center pre-identified as serving said present physical location based upon said determined present physical location of said calling party.

14. The method of claim 13 wherein said universally known calling number is 911.

15. The method of claim 13 wherein said determining comprises:

determining a geospatial coordinate for the present physical location of the calling party.

16. The method of claim 15 further comprising:

identifying said service center to which the calling party is to be routed based upon said determined geospatial coordinate.

17. The method of claim 15 wherein said determining said geospatial coordinate comprises:

determining the geospatial coordinate based at least in part on an automatic number identification (ANI) determined for the received emergency call.

18. The system of claim 15 wherein said geospatial coordinate comprises an XY coordinate.

19. The method of claim 15 wherein said geospatial coordinate comprises an XYZ coordinate.

20. The method of claim 13 further comprising:

formatting information into a format desired for the service center pre-identified as serving said present physical location.

21. The method of claim 20 wherein said information comprises a determined geospatial coordinate.

22. A system for emergency call routing, said system comprising:

an interface for receiving an emergency call placed by a caller;

a geospatial coordinate generator for determining a geospatial coordinate for the location of the caller; and

identifying logic for identifying a proper Public Safety Answering Point (PSAP) to which the emergency call is to be routed based upon said determined geospatial coordinate.

23. The system of claim 22 further comprising:

formatting logic for formatting information into a format desired for the identified PSAP.

24. The system of claim 23 wherein said information comprises the determined geospatial coordinate.

25. The system of claim 23 wherein said information comprises information pre-stored in a database about said caller.

26. The system of claim 25 wherein said information pre-stored in the database about said caller comprises at least one of:

a contact number for another party to be notified of the emergency call, and a calendar of the caller.

27. The system of claim 23 further comprising:

routing logic for routing said emergency call and said formatted information to said determined PSAP.

28. The system of claim 22 wherein said geospatial coordinate comprises an XY coordinate.

29. The system of claim 22 wherein said geospatial coordinate comprises an XYZ coordinate.

30. The system of claim 22 wherein said geospatial coordinate generator determines the geospatial coordinate based at least in part on an automatic number identification (ANI) determined for the emergency call.
