Patent ID: 8701164

Claim:
A method for enhancing scalability and resource allocation in relation to handover of a mobile node between networks, including establishing multiple tunnels with multiple neighboring target networks that the mobile node may move to, comprising: while the mobile node is in a current network, performing multiple pre-authentications between the mobile node and authentication agents in multiple neighboring target networks; and while the mobile node is in the current network, performing multiple binding update prior to layer 2 movement of the mobile node; wherein said mobile node completes each of pre-authentication, pre-configuration and binding update in relation to multiple candidate target networks while in the current network; wherein said mobile node is configured so as to store multiple IP addresses of neighboring networks in cache for a period of time; further including establishing transient tunnels with target routers in the multiple neighboring target networks; further including for said performing multiple binding update, said mobile node transmits a binding update with multiple IP addresses obtained from the neighboring networks to the correspondent node (CN) and the correspondent node sends multiple transient streams to the mobile node using the transient tunnels; and further including sending another binding update from the mobile node after handover of the mobile node with a new single contact address set to where the mobile node has moved, such that the mobile node stops sending media to other neighboring networks where the mobile node did not move.
