Abstract

A method to reroute a call with a first and second termination point based upon Quality of Service (QoS) is disclosed. The method comprises establishing a quality of service threshold, connecting a first communication path between the two termination points through the network elements, testing said quality of service along said first communication path and generating a quantitative value based at least in part on said quality of service. The method continues with establishing a second communication path between the network elements if the quantitative value is not up to the level of said quantitative quality of service threshold; and rerouting said data transmission through the newly established second communication path between the network elements while maintaining said termination points.

Claims

1. A method to reroute a data transmission, such as a call, having a first termination point, a second termination point, a first network element and a second network element based upon Quality of Service (QoS), said method comprising:

establishing a quality of service threshold;

connecting a first communication path between said first and second termination points through said first and second network elements;

testing said quality of service along said first communication path;

generating a quantitative value based at least in part on said quality of service;

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

rerouting said data transmission through said established second communication path between said first and second network element while maintaining said termination points.

2. 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 network than said first communication path.

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 utilizing a different transport type than said first communication path.

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

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

6. The method as set forth in claim 1 further comprising testing an end device associated with said first or second termination point.

7. The method as set forth in claim 1 further comprising notifying a service provider that said data transmission was rerouted due to quality of service.

8. The method as set forth in claim 1 further comprising communicating that said data transmission was rerouted to a billing database.

9. The method as set forth in claim 1 wherein said testing said quality of service along said first communication path is done continuously.

10. The method as set forth in claim 1 wherein said testing said quality of service is conducted by using a loop back method.

11. The method as set forth in claim 1 wherein said testing said quality of service is conducted by using a bong tone method.

12. The method as set forth in claim 1 wherein said testing said quality of service is conducted by using a audio logo method.

13. A system having a first and second termination point that enables a data transmission to be rerouted between said first and second network element 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;

a first and second network element, said first and second network element having a first communication path set between them; and

a rerouting module adapted to set up a second communication path between said first and second network element and reroute said data transmission through said second communication path while maintaining said data transmission between said first and second termination points if said quantitative value for quality of service of said first communication path is not to the level of said quantitative quality of service threshold.

14. A system as set forth in claim 13 wherein said first or second network element is a gateway.

15. A system as set forth in claim 13 wherein said first or second network element is a switch.

16. A system as set forth in claim 13 wherein said data transmission is a telephone call.

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

18. A system for rerouting a data transmission, such as a call, comprising:

a means for establishing a quality of service threshold;

a means for connecting a first communication path between said first and second termination points through said first and second network elements along;

a means for testing said quality of service along said first communication path;

a means for generating a quantitative value based at least in part on said quality of service;

a means for establishing a second communication path between said first and second network element for said data transmission if said quantitative value is not up to the level of said quantitative quality of service threshold;

.and

a means for rerouting said data transmission through said established second communication path between said first and second network element while maintaining said termination points.

19. The system as set forth in claim 18 further comprising a means for rerouting said data transmission through said established second communication path between said first and second network element while said second communication path is in a different network than said first communication path.

20. The system as set forth in claim 18 further comprising a means for rerouting said data transmission through said established second communication path between said first and second network element while said second communication path is in a different transport than said first communication path.
