Abstract
The present invention concerns a mobile packet communication system that supports data communications, including Internet communications, in a high-speed mobile communication system such as a cellular communication network, and integrates a mobile network and a fixed network on a common platform while providing the capability to select an optimum route. Location registration servers--to--each store in a one-to-one fashion the addresses of subscriber nodes--to--currently serving mobile terminals--to--each assigned a packet address, or store in a one-to-one fashion the addresses of gate nodes--to--connected to fixed equipment--to--each assigned a packet address, and a transmitting node, which is a subscriber node or a gate node, temporarily stores a receiving node address reported from the corresponding one of the location registration servers--to--, and transfers subsequent packets directly to the receiving node by using the temporarily stored receiving node address.
