Abstract

A system and method automatically routes in-vehicle emergency calls to an automatic crash notification (ACN) call center using information provided by the calling mobile device in the call set up message. An operator at the ACN call center is presented with an identification of a public safety answering point (PSAP) that serves the location of the vehicle. The ACN operator may then conference in the PSAP if needed. The provided information is displayed at both the ACN operator'"'"'s position and at the PSAP. Alternatively, the call is routed to the PSAP first or to both the PSAP and the ACN call center simultaneously.

Claims

1. A method for routing an emergency call from an in-vehicle mobile device comprising:

receiving a set up message from said in-vehicle mobile device, said set up message including a plurality of parameters;

determining a destination automatic crash notification (ACN) call center based on one or more of said parameters;

determining a destination public safety answering point (PSAP) based on one or more of said parameters; and

routing said emergency call to said destination ACN call center.

2. A method in accordance with claim 1 further comprising:

routing said emergency call to said PSAP.

3. A method in accordance with claim 1 further comprising:

setting up a three-way call among said in-vehicle mobile device, said destination ACN call center and said destination PSAP.

4. A method in accordance with claim 1 further comprising:

forwarding an identification of said destination PSAP to said destination ACN call center responsive to a request from said destination ACN call center.

5. A method in accordance with claim 1 further comprising:

setting up a three-way call among said in-vehicle mobile device, said destination ACN call center and said destination PSAP responsive to a request from said destination ACN call center.

6. A method in accordance with claim 1 further comprising:

determining a language based on said one or more parameters; and

wherein determining a destination ACN call center is based on said language.

7. A method in accordance with claim 1 further comprising:

determining a language based on said one or more parameters; and

wherein determining a destination PSAP is based on said language.

8. A method for routing an emergency call from an in-vehicle mobile device comprising:

receiving a set up message from said in-vehicle mobile device, said set up message including a plurality of parameters;

determining a destination automatic crash notification (ACN) call center based on one or more of said parameters;

determining a destination public safety answering point (PSAP) based on one or more of said parameters; and

routing said emergency call to said destination PSAP call center.

9. A method in accordance with claim 8 further comprising:

routing said emergency call to said PSAP.

10. A method in accordance with claim 8 further comprising:

setting up a three-way call among said in-vehicle mobile device, said destination ACN call center and said destination PSAP.

11. An emergency location center comprising:

a signaling interface unit configured to receive messages containing one or more parameters from a network and sending destination numbers back through the network;

a database configured to store a plurality of parameters in relation to a plurality of destination PSAP and ACN call center numbers; and

a processor coupled to said signaling interface unit and said database and configured to apply one or more of said one or more parameters to said database to select one of said plurality of destination PSAP numbers and one of said plurality of destination ACN call center numbers and return said selected destination PSAP number and said selected ACN call center number to said signaling interface unit for forwarding through said network.

12. An emergency location center in accordance with claim 11 wherein one of said parameters comprises location coordinates.

13. An emergency location center in accordance with claim 12 wherein said database comprises a coordinate routing database.

14. An emergency location center in accordance with claim 11 wherein one of said parameters indicates language preference and said database comprises a language routing database.
