Abstract

An emergency system includes a gateway and a database in communication with the gateway. The database comprises first routing information for establishing a first communication link between a communication device and a controller, second routing information for establishing a second communication link between the gateway and the controller, wherein the second routing information is correlated to the first routing information; and location data associated with the communication device. Upon receiving identification information related to the communication device, the gateway retrieves the first routing information from the database and provides the first routing information to a switch. The gateway retrieves the second routing information from the database and uses the second routing information to establish a second communication link with the controller, and the gateway retrieves the location data from the database.

Claims

1. An emergency system, comprising:

a gateway;

a database in communication with the gateway, wherein the database comprises;

first routing information for establishing a first communication link between a communication device and a controller;

second routing information for establishing a second communication link between the gateway and the controller; and

location data associated with the communication device;

wherein upon receiving identification information related to the communication device, the gateway receives the first routing information for establishing the first communication link between the communication device and the controller, the gateway receives the second routing information and uses the second routing information to establish a second communication link with the controller, and the gateway receives the location data from the database.

2. The system of claim 1, wherein the first communication link to the controller is a voice telephone link.

3. The system of claim 2, wherein the voice telephone link comprises any one of a wireline and wireless voice telephone link.

4. The system of claim 1, wherein the second communication link to the controller is a packet data link.

5. The system of claim 4, wherein the packet data link is a TCP/IP link.

6. The system of claim 1, wherein the first communication link is established over a first network and the second communication link is established over a second network.

7. The system of claim 6, wherein the first network is a public switched telephone network.

8. The system of claim 6, wherein the second network is the Internet.

9. The system of claim 1, wherein the database further comprises information for determining the location coordinates of the communication device, wherein the communication device is a wireless communication device.

10. A method of delivering first and second communications associated with an emergency call from a communication device, comprising:

receiving identification information associated with a communication device at a gateway;

receiving first routing information from a database for establishing a first communication link between the communication device and a controller;

receiving second routing information from the database for establishing a second communication link between the gateway and the controller;

receiving location data associated with the communication device; and

wherein information transmitted via the first communication link and the location data transmitted via the second communication link arrives at the controller at substantially the same time.

11. The method of claim 10, wherein the first communication link to the controller is a voice telephone link.

12. The method of claim 11, wherein the voice telephone link comprises any one of a wireline and wireless voice telephone link.

13. The method of claim 10, wherein the second communication link comprises a packet data link.

14. The method of claim 13, wherein the packet data link further comprises a TCP/IP link.

15. The method of claim 10, wherein the first communication link is over a first network and the second communication link is over a second network.

16. The method of claim 15, wherein the first communication link is over a public switched telephone network.

17. The method of claim 15, wherein the second communication link is over the Internet.

18. The method of claim 10, further comprising retrieving location coordinates information for determining the location of the communication device, wherein the communication is a wireless communication device.
