Abstract

A communication network comprises a public safety answering point, a responder device, and a customer information system. The public safety answering point receives a call from a caller and signaling for the call. The signaling indicates a key associated with the call. The public safety answering point transfers dispatch information that identifies the key to the responder device. The responder device receives the dispatch information and generates and transmits a context request that indicates the key. The responder device receives a context response that includes a context information. The customer information system receives the context request, processes the context request to select the context information from a plurality of context information based on the key, and transfers the context response.

Claims

1. A communication network for handling emergency calls comprising:

a public safety answering point configured to receive a call from a caller and signaling for the call that indicates a key associated with the call and transfer dispatch information that identifies the key, wherein the key comprises a media access control (MAC) address;

a mobile responder device configured to receive the dispatch information, generate and transmit a context request that indicates the key, and receive a context response that includes a context information; and

a customer information system configured to receive the context request, process the context request to select the context information from a plurality of context information based on the key, and transfer the context response.

2. The communication network of claim 1 wherein the public safety answering point is further configured to transfer a location query that indicates the key and receive a location response that identifies a location of the call, and wherein the dispatch information identifies the location of the call.

3. The communication network of claim 2 wherein the public safety answering point transfers the location query to a location provisioning system and receives the location response from the location provisioning system.

4. The communication network of claim 3 further comprising a call processing system configured to receive a call request for the call that includes a caller identification, transmit a key request to the location provisioning system that includes the caller identification, receive a key response from the location provisioning system that indicates the key, and transfer the call and the call signaling for the call to the public safety answering point.

5. The communication network of claim 4 wherein the call processing system is further configured to transfer the key and the caller identification to the customer information system.

6. The communication network of claim 5 wherein the customer information system is configured to store a plurality of context information in association with a plurality of caller identifications, receive and process the key and the caller identification to select the context information from the plurality of context information based on the caller identification and store the key in association with the context information.

7. The communication network of claim 1 wherein the context information comprises health information for the caller.

8. The communication network of claim 7 wherein the caller inputs the health information into the customer information system.

9. A method of operating a communication network to handle emergency calls, the method comprising:

receiving in a public safety answering point a call from a caller and signaling for the call that indicates a key associated with the call, wherein the key comprises a media access control (MAC) address;

transferring from the public safety answering point dispatch information that identifies the key;

receiving in a mobile responder device the dispatch information;

generating and transmitting from the mobile responder device a context request that indicates the key;

receiving in the mobile responder device a context response that includes a context information;

receiving the context request in a customer information system;

in the customer information system, processing the context request to select the context information from a plurality of context information based on the key; and

transferring the context response from the customer information system.

10. The method of claim 9 further comprising:

transferring a location query that indicates the key from the public safety answering point; and

receiving in the public safety answering point a location response that identifies a location of the call;

wherein the dispatch information identifies the location of the call.

11. The method of claim 10 comprising transferring the location query to a location provisioning system and receiving the location response from the location provisioning system.

12. The method of claim 11 further comprising:

receiving in a call processing system a call request for the call that includes a caller identification;

transmitting from the call processing system to a location provisioning system a key request that includes the caller identification;

receiving in the call processing system from the location provisioning system a key response that indicates the key; and

transferring the call and the call signaling for the call from the call processing system to the public safety answering point.

13. The method of claim 12 further comprising transferring the key and the caller identification from the call processing system to the customer information system.

14. The method of claim 13 further comprising:

in the customer information system, storing a plurality of context information in association with a plurality of caller identifications, receiving and processing the key and the caller identification to select the context information from the plurality of context information based on the caller identification and to store the key in association with the context information.

15. The method of claim 9 wherein the context information comprises health information for the caller.

16. The method of claim 15 wherein the caller inputs the health information into the customer information system.

17. A computer system in a public safety answering point, the computer system comprising:

an interface configured to receive a call from a caller and signaling for the call that indicates a key associated with the call, wherein the key comprises a media access control (MAC) address;

a processing system configured to process the signaling for the call to generate a location query that identifies the key and dispatch information that identifies the key;

the interface further configured to transfer the location query to a location provisioning system to obtain a location of the caller and transfer the dispatch information to a mobile responder device operated by a first responder.

18. A method of operating a computer system in a public safety answering point, the method comprising:

receiving a call from a caller and signaling for the call that indicates a key associated with the call, wherein the key comprises a media access control (MAC) address;

processing the signaling for the call to generate a location query that identifies the key and dispatch information that identifies the key;

transferring the location query to a location provisioning system to obtain a location of the caller; and

transferring the dispatch information to a mobile responder device operated by a first responder.
