Abstract

A method to reroute a call with a first termination point and a second termination point based upon Quality of Service (QoS) is disclosed. The method comprises establishing a quantitative QoS threshold, establishing a first communication path through a network for a data transmission such as a call, testing the QoS of the first communication path during the call or call set up and generating a quantitative value based upon said QoS. The method further includes establishing a second communication path for the call if the quantitative value is not to the level of the quantitative QoS threshold. Finally, the method includes rerouting the call from said first communication path to the second communication path while maintaining the first termination point.

Claims

1. A method to reroute a data transmission having a first termination point and a second termination point based upon quality of service (QoS) comprising:

establishing a quantitative quality of service threshold;

establishing a first communication path through a network for the data transmission;

testing the quality of service of said first communication path during the data transmission or data transmission set up;

generating a quantitative value based upon said quality of service;

establishing at least a second communication path for the data transmission if said quantitative value is not up to the level of said quantitative quality of service threshold; and

rerouting the data transmission from said first communication path to said at least second communication path while maintaining at least said first termination point.

2. The method as set forth in claim 1 wherein the data transmission is a call.

3. The method as set forth in claim 1 further comprising rerouting said data transmission from said first communication path to said second communication path while said second communication path is in a different network than said first communication path.

4. The method as set forth in claim 1 further comprising rerouting said data transmission from said first communication path to said second communication path while said second communication path is utilizing a different transport type than said first communication path.

5. The method as set forth in claim 1 further comprising connecting said second communication path to a third termination point.

6. The method as set forth in claim 5, further comprising testing the availability of said third termination point.

7. The method as set forth in claim 5, further comprising displaying a special signal on a device associated with said third termination point.

8. The method as set forth in claim 1, further comprising testing the quality of service of said second communication path.

9. The method as set forth in claim 1, further comprising generating a report comprising the reasons for rerouting said first communication path.

10. The method as set forth in claim 8, further comprising sending said report to a telephone service provider.

11. The method as set forth in claim 1, further comprising communicating that said first communication path was rerouted to a billing database.

12. A system that enables a call to be rerouted comprising:

a quantitative quality of service threshold;

a quality of service test module adapted to measure the quality of service and derive a quantitative value for quality of service; and

a rerouting module adapted to set up at least a second communication path if said quantitative value for quality of service of a first communication path is not to the level of said quantitative quality of service threshold.

13. A system as set forth in claim 12 wherein said second communication path is in a different network than said first communication path.

14. A system as set forth in claim 12 wherein said second communication path is in a different transport type than said first communication path.

15. A system as set forth in claim 12 wherein said rerouting module and quality of service testing module are housed within a switch.

16. A system to reroute a call having a first termination point and a second termination point based upon quality of service (QoS) comprising:

a means for establishing a quantitative quality of service threshold;

a means for establishing a first communication path through a network for a call;

a means for testing the quality of service of said first communication path during the call or call set up;

a means for generating a quantitative value based upon said quality of service;

a means for establishing at least a second communication path for the call if said quantitative value is not up to the level of said quantitative quality of service threshold; and

a means for rerouting said call from said first communication path to said at least second communication path while maintaining at least said first termination point.

17. The system as set forth in claim 16 further comprising a means for rerouting said call from said first communication path to said second communication path while said second communication path is in a different network than said first communication path.

18. The system as set forth in claim 16 further comprising a means for rerouting said call from said first communication path to said second communication path while said second communication path is utilizing a different transport type than said first communication path.

19. The system as set forth in claim 16 further comprising a means for connecting said second communication path to a third termination point.

20. The system as set forth in claim 19, further comprising a means for testing the availability of said third termination point.

21. The method as set forth in claim 19, further comprising displaying a special signal on a device associated with said third termination point.
