Abstract

Methods and systems for routing calls include determining location information identifying a location of a caller. A destination for a call from the caller is determined based on the location information and a geographic service area of the destination. The call is routed to the destination.

Claims

1. A method for routing calls, comprising:

determining location information identifying a location of a caller;

determining a plurality of media types within a call from the caller;

determining a plurality of emergency service providers for a call from the caller based on the location information, a geographic service area of the emergency service providers, and the determined plurality of media types; and

routing the call to the emergency service providers, with different subsets of data within the call, corresponding to respective determined media types, being routed to different emergency service providers from the determined plurality of emergency service providers.

2. The method of claim 1, further comprising validating the location information based on an originating medium of the call.

3. The method of claim 2, wherein validating the location information comprises determining the originating medium of the call and determining a level of location precision that can be associated with the originating medium.

4. The method of claim 1, wherein determining location information comprises querying a communication service provider that originated the call.

5. The method of claim 1, further comprising routing the call to a fallback emergency service dispatcher if the location information cannot be determined or if there is no emergency service provider that has a geographic service area that includes the location of the caller.

6. The method of claim 1, wherein routing the call to the emergency service providers comprises routing call contents and the location information to the emergency service providers.

7. The method of claim 1, wherein the call is a call for emergency services and wherein routing the call to the emergency service providers comprises routing the call over an emergency services IP network.

8. The method of claim 1, wherein the plurality of media types include voice information and biometric information and wherein the voice information is routed to an emergency service dispatcher and the biometric information is routed to a doctor.

9. A non-transitory computer readable storage medium comprising a computer readable program for routing calls, wherein the computer readable program when executed on a computer causes the computer to perform the steps of:

determining location information identifying a location of a caller;

determining a plurality of media types within a call from the caller;

determining a plurality of emergency service providers for a call from the caller based on the location information, a geographic service area of the emergency service providers, and the determined plurality of media types; and

routing the call to the emergency service providers, with different subsets of data within the call, corresponding to respective determined media types, being routed to different emergency service providers from the determined plurality of emergency service providers.

10. A call routing system, comprising:

an incoming interface configured to receive a call from a caller through a communication service provider;

an outgoing interface configured to send the call to a network having one or more call destinations;

a location module configured to determine location information identifying a location of the caller;

a routing module comprising a processor configured to determine a plurality of media types within the call, to determine a plurality of emergency service providers for the call based on the location information, a geographic service area of the emergency service providers, and the determined plurality of media types, and to route the call to the emergency service providers using the outgoing interface, with different subsets of data within the call, corresponding to respective determined media types, being routed to different emergency service providers from the determined plurality of emergency providers.

11. The system of claim 10, wherein the location module is further configured to validate the location information based on an originating medium of the call.

12. The system of claim 11, wherein the location module is further configured to determine the originating medium of the call and to determine a level of location precision that can be associated with the originating medium.

13. The system of claim 10, wherein the location module is further configured to query a communication service provider that originated the call using the incoming interface.

14. The system of claim 10, wherein the routing module is further configured to route the call to a fallback destination if the location information cannot be determined or if there is no destination that has a geographic service area that includes the location of the caller.

15. The system of claim 10, wherein the routing module is further configured to route call contents and the location information to the emergency service providers.

16. The system of claim 10, wherein the call is a call for emergency services and wherein the routing module is further configured to route the call over an emergency services IP network.

17. The system of claim 10, wherein the incoming interface is configured to receive calls from a plurality of communication service providers and wherein the outgoing interface module is configured to send calls to one or more of a plurality of networks.
