1. A method for providing a triggering mechanism in an all-IP wireless communication system, comprising the steps of:
- probing a plurality of 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.

Abstract
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.

11. A method for providing a triggering mechanism in an all-IP wireless communication system, comprising the steps of:
-
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. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A method for providing triggering mechanism in an all-IP wireless communication system, comprising the steps of:
-
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. - View Dependent Claims (19, 20, 21, 22, 23)
