Mobile IP communication scheme using visited site or nearby network as temporal home network
First Claim
1. A mobile computer device capable of carrying out communications while moving over inter-connected networks including a first network that is an original home network of the mobile computer device and a second network that is a visited site network of the mobile computer device, the mobile computer device comprising:
- an exchange processing unit configured to receive a network configuration information of the second network from a management device of the second network at a time of moving from the first network to the second network, when it is possible to receive the network configuration information from the management device of the second network; and
a communication control unit configured to control communications by selecting a new communication setting that indicates the second network as a home network of the mobile computer device or an original communication setting that indicates the first network as a home network of the mobile computer device, when the network configuration information received from the management device of the second network contains a home address information of the management device of the second network.

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. 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.
