Claim Text:
1. A method for use in interconnected communications networks including movable networks and mobile hosts, comprising: providing a set of globally-reachable attachment registers, where at least some of the movable networks and mobile hosts each has a corresponding attachment register and where at least some of the globally-reachable attachment registers are located in different network entities, and storing information in the corresponding attachment registers that establishes one or more logical links between the attachment registers, wherein the logical links between certain ones of the attachment registers are useable to perform one or more network communication functions and wherein the globally-reachable attachment registers are arranged as a distributed database and are not arranged in a single register entity, and wherein one of the movable networks changes from a first point of attachment in the interconnected communications networks at a first neighbor node to a second point of attachment at a second neighbor node, the method further comprising: updating the attachment register corresponding to the one movable network to change a logical link from the attachment register corresponding to the first neighbor node to the attachment register corresponding to the second neighbor node; and wherein, when the one moveable network moves to the second point of attachment at the second neighbor node, all lower level mobile hosts in the movable network need not update their mobility registrations with a central location register because of the updating of the globally-reachable attachment register corresponding to the one movable network to thereby avoid a large number of registrations or other location updates that would otherwise need to be signaled and processed.
