Abstract

A technique for routing and controlling emergency calls is disclosed. In one particular exemplary embodiment, the technique may be realized as a method for routing and controlling emergency calls. The method may comprise intercepting an emergency call from a caller. The method may also comprise causing the caller to experience a predetermined delay. The method may additionally comprise communicating a message to the caller during the predetermined delay.

Claims (52)

1. A method for routing and controlling emergency calls, the method comprising:

intercepting, at a telephone exchange, an emergency call from a caller;

causing the caller to experience a pre-programmed delay; and

communicating a message to the caller during the pre-programmed delay.

2. The method according to claim 1 , further comprising:

extracting a setup message from the emergency call, wherein the setup message comprises at least a calling line identification (CLID) and a dialed number;

verifying the calling line identification (CLID) and the dialed number based on a query to one or more databases;

modifying the setup message based on the query; and

routing the emergency call based on the setup message.

3. The method according to claim 1 , further comprising:

recording the emergency call.

4. The method according to claim 3 , further comprising:

time-stamping the recorded emergency call.

5. The method according to claim 1 , wherein the emergency call originates from within a private network.

6. The method according to claim 5 , further comprising:

providing notification to on-site personnel associated with the private network.

7. The method according to claim 1 , wherein the one or more databases are selected from a group consisting of a routing database and a CLID database.

8. The method according to claim 1 , wherein the one or more databases are associated with an automatic location identification database.

9. The method according to claim 1 , wherein the one or more databases are associated with a location identification server.

10. At least one signal embodied in at least one carrier wave for transmitting a computer program of instructions configured to be readable by at least one processor for instructing the at least one processor to execute a computer process for performing the method as recited in claim 1 .

11. At least one processor readable carrier for storing a computer program of instructions configured to be readable by at least one processor for instructing the at least one processor to execute a computer process for performing the method as recited in claim 1 .

12. A system for routing and controlling emergency calls, the system comprising:

means for intercepting an emergency call from a caller;

means for causing the caller to experience a pre-programmed delay; and

means for communicating a message to the caller during the pre-programmed delay.

13. The system according to claim 12 , further comprising:

means for extracting a setup message from the emergency call, wherein the setup message comprises at least a calling line identification (CLID) and a dialed number;

means for verifying the calling line identification (CLID) and the dialed number based on a query to one or more databases;

means for modifying the setup message based on the query; and

means for routing the emergency call based on the setup message.

14. The system according to claim 12 , further comprising:

means for recording the emergency call.

15. The system according to claim 14 , further comprising:

means for time-stamping the recorded emergency call.

16. The system according to claim 12 , wherein the emergency call originates from within a private network.

17. The system according to claim 16 , further comprising:

at least one annunciator for providing notification to on-site personnel associated with the private network.

18. The system according to claim 12 , wherein the one or more databases are selected from a group consisting of a routing database and a CLID database.

19. The system according to claim 12 , further comprising an automatic location identification database.

20. The system according to claim 12 , further comprising a location identification server.

21. A system for routing and controlling emergency calls, the system comprising:

a telephone exchange that intercepts an emergency call from a caller; and

an emergency call routing and control device that:

causes the caller to experience a pre-programmed delay; and

communicates a message to the caller during the pre-programmed delay.

22. The system according to claim 21 , wherein the emergency call routing and control device:

extracts a setup message from the emergency call, wherein the setup message comprises at least a calling line identification (CLID) and a dialed number;

verifies the calling line identification (CLID) and the dialed number based on a query to one or more databases;

modifies the setup message based on the query; and

routes the emergency call based on the setup message.

23. The system according to claim 21 , wherein the emergency call routing and control device comprises a time slot interchange.

24. The system according to claim 21 , wherein the emergency call routing and control device is coupled to the telephone exchange via a T1 PRI trunk.
