Layer three quality of service aware trigger
View Patent ↗A method for providing a triggering mechanism in an all-IP wireless communication system. A plurality of communication paths are established between a mobile terminal and a correspondent node to obtain at least one QoS parameter associated with each communication path. Each communication path that provides a predetermined acceptable level of performance is then identified. A handoff trigger is then generated to the communication path that provides the highest level of performance to the mobile terminal.
1. A method for providing a triggering mechanism in an all-IP wireless communication system, comprising:
probing a plurality of end-to-end communication paths between a mobile terminal and a correspondent node to obtain at least one QoS parameter associated with each said communication path;
identifying each said communication path that provides a predetermined acceptable level of performance; and
generating a handoff trigger to said communication path that provides the highest level of performance to said mobile terminal.
2. The method of claim 1 , wherein said at least one QoS parameter is selected from a group of QoS parameters consisting of packet delay, packet jitter, packet loss and bandwidth.
3. The method of claim 1 , further comprising ranking each said communication path according to a predicted level of performance.
4. The method of claim 3 , wherein ranking is performed using a weighted-based ranking.
5. The method of claim 3 , wherein ranking is performed using a perception-based ranking.
6. The method of claim 1 , wherein said correspondent node comprises a fixed terminal.
7. The method of claim 1 , wherein said correspondent node comprises a mobile terminal.
8. The method of claim 1 , further comprising considering a cost factor.
9. The method of claim 1 , further comprising considering a user preference setting on said mobile terminal.
10. The method of claim 1 , further comprising considering load balancing on said all-IP wireless communication system.
11. The method of claim 1 , wherein the at least one QoS parameter comprises a layer 3 QoS evaluation parameter corresponding to each said end-to-end communication path.
12. A method for providing a triggering mechanism in an all-IP wireless communication system, comprising:
establishing a plurality of end-to-end communication paths between a mobile terminal and a correspondent node;
obtaining at least one QoS parameter for each said end-to-end communication path;
identifying each said end-to-end communication path that satisfies a predetermined acceptable level of performance; and
generating a handoff trigger to said end-to-end communication path that provides the highest QoS to said mobile terminal.
13. The method of claim 12 , wherein said at least one QoS parameter is selected from a group of QoS parameters consisting of packet delay, packet jitter, packet loss and bandwidth.
14. The method of claim 12 , further comprising ranking each said communication path according to a predicted level of performance.
15. The method of claim 14 , wherein ranking is performed using a weighted-based ranking.
16. The method of claim 14 , wherein ranking is performed using a perception-based ranking.
17. The method of claim 12 , wherein said correspondent node comprises a fixed terminal.
18. The method of claim 12 , wherein said correspondent node comprises a mobile terminal.
19. The method of claim 12 , wherein the at least one QoS parameter comprises a layer 3 QoS evaluation parameter corresponding to each said end-to-end communication path.
20. A method for providing triggering mechanism in an all-IP wireless communication system, comprising:
providing a mobile terminal connected to a plurality of AP/R pairs;
obtaining for each AP/R pair at least one QoS parameter that is defined by an end-to-end communication path between said mobile terminal and a correspondent node;
identifying each said AP/R pair that passes a predefined QoS requirement associated with said QoS parameter;
ranking said AP/R pairs according to a predicted level of performance using said at least one QoS parameter; and
generating a handoff trigger directing said mobile terminal to hand off to said AP/R pair providing a highest QoS to said mobile terminal.
21. The method of claim 20 , wherein said at least one QoS parameter is selected from a group of QoS parameters consisting of packet delay, packet jitter, packet loss and bandwidth.
22. The method of claim 20 , wherein ranking is performed using a weighted-based ranking.
23. The method of claim 20 , wherein ranking is performed using a perception-based ranking.
24. The method of claim 20 , wherein said correspondent node comprises a fixed terminal.
25. The method of claim 20 , wherein said correspondent node comprises a mobile terminal.
26. The method of claim 20 , wherein the at least one QoS parameter comprises a layer 3 QoS evaluation parameter corresponding to each said end-to-end communication path.
