Methods and apparatus for quickly exploiting a new link during hand-off in a wireless network
Abstract:
A method to deliver traffic to a mobile node that is undergoing a hand-off between two Access Routers (AR) is described. The method of the present invention operates to perform the following. Decrease, or minimize, delays between the time the old link breaks and the first packet is sent from the new link. Reduce or eliminate packet bursts from old to new Access Router (AR) when an old (existing) link breaks. Ensure that packets are neither lost nor duplicated during hand-off. Maintain Quality of Service (QoS) control of delivery order to the Mobile Node (MN). Make good or best use of multiple links during Make before break hand-off. Support both uplink and downlink traffic.
