<p>PROBLEM TO BE SOLVED: To select an optimum route and to integrate a mobile network and a fixed network with a common platform in the case of supporting data communication such as internet communication in the high speed mobile communication system of a cellular communication network or the like. SOLUTION: Location registration servers 1-4-1 to 1-4-3 store the addresses of subscriber nodes 1-2-1 to 1-2-3 accommodating mobile terminals 1-1-1 to 1-1-2, to which packet addresses are given, for each of these mobile terminals. Besides, the addresses of gate nodes 1-3-1 to 1-3-2 connected to fixed station devices 1-5-1 to 1-5-2, to which packet addresses are given, are stored for each of these fixed station devices, and concerning the outgoing nodes of subscriber nodes or gate nodes, the addresses of incoming nodes reported from the location registration servers 1-4-1 to 1-4-3 are temporarily preserved. While using these temporarily preserved address of the incoming nodes, succeeding packets are directly transferred to the incoming nodes.</p> |
