  • Context transfer systems and methods in support of mobility
    Patent number: 8351396
    Abstract: A broad aspect of the invention provides a method of providing mobility support for a mobile node's traffic. The method involves maintaining context information for the mobile node on each of a first plurality of network nodes carrying the traffic; and proactively transferring and maintaining at least a portion of the context information in a plurality of network nodes which are not carrying the traffic, but which are candidates for carrying the traffic due to mobility of the mobile node. The method typically further involves defining and maintaining a definition of the second plurality of network nodes. In one embodiment of the invention, this involves adding a particular network node to the second plurality when the particular network node becomes a candidate for carrying the traffic, removing a particular network node from the second plurality when the particular network node is no longer a candidate for carrying the traffic.
