Abstract
A method and system for supporting mobility of a mobile node in which, when it is recognized that the mobile node has moved into a foreign sub-network, the mobile node is allocated, by its home sub-network, a new Internet protocol address suitable for a prefix of the foreign sub-network after movement when moving out of an area of the home sub-network into the foreign sub-network so that route optimization is implemented. Since direct communication is made between a mobile node and a correspondent node without passing a network where the mobile node existed before movement, it is possible to implement the route optimization. There is no generation of packet overhead since Internet protocol tunneling technology is not applied upon routing.
