Abstract
A mobile IP communication scheme in which a visited site or nearby network of a mobile computer is utilized as a temporal home network of a mobile computer is disclosed. The mobile computer exchanges a message with a mobile computer management device provided in a visited site or nearby network from a visited site, so as to acquire a network configuration information of the visited site or nearby network, and sets the acquired network configuration information in a communication program to be used in carrying out communications. The mobile computer management device leases a temporal home address to be used by an externally located mobile computer in response to a request message from the mobile computer, and registers the mobile computer as a mobile node which regards a network to which the mobile computer management device belongs as a home network, in response to a registration message from the mobile computer.
