摘要:
A mobile IP communication scheme capable of authenticating an individual user who is operating the mobile computer when the mobile computer is connected to a visited site network and transmits a current location registration message to the home agent is disclosed. A user authentication to judge a properness of a user of the mobile computer is carried out according to a user input based information, and the current location of the mobile computer is registered at the mobile computer management device (home agent) when the user is judged as a proper user. The user authentication can be carried out either at the mobile computer management device according to a user input based information received from the mobile computer, or at the mobile computer according to an information entered by the user at the mobile computer.

摘要:
A mobile IP communication scheme in which the mobile computer can be operated using the mobile communication protocol such as Mobile IP even in the case where the home network is operated by the dynamic address allocation protocol such as DHCP is disclosed. The current location registration message to be transmitted by the mobile computer from the visited site to the mobile computer management device contains an information indicating that the dynamic address allocation has been received at the home network and an information capable of identifying the mobile computer, and the mobile computer management device carries out exchanges with the dynamic address management server on behalf of the mobile computer, so that the mobile computer which has received the dynamic address allocation at the home network can be operated at the visited site by using the mobile communication protocol.
摘要:
A mobile IP communication scheme for supporting a mobile computer moving over different address spaces is disclosed. A packet relay device for relaying packets having an address of the mobile computer device as a destination or source is provided at a border between a private address space and a global address space, where the packet relay device has a packet receiving unit for receiving a packet in a first format using a global address which is transmitted by the mobile computer for a location registration from a visited site managed by a global address system, and checking a content of the packet, and a packet transfer unit for transferring the packet in a second format using a private address, to a correspondent computer in a home network of the mobile computer managed by a private address system, according to the content of the packet.

摘要:
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.
摘要:
A mobile computing scheme capable of carrying out a proper packet transfer according to a current location of the mobile computer by accounting for the network operating policy. A mobile computer carries out a prescribed communication processing according to recognition results as to whether the mobile computer is located inside or outside the home network at which a mobile computer management device of the mobile computer is provided, and whether or not there exists a packet processing device which has a packet transmitted by at least one of the mobile computer and a correspondent computer as an encryption and authentication processing target. Also, a packet processing device carries out a prescribed transfer processing according to recognition results as to whether at least one of a source computer and a destination computer of a packet to be transferred is a moving mobile computer which is moving outside its home network, and whether or not there exists a packet processing device which has a packet transmitted by at least one of the source computer and the destination computer as an encryption and authentication processing target.
