Abstract
A mobile node includes a plurality of transceivers, has a network conforming to network-based mobility as its home link and performs position registration to a positional managing apparatus and performs position registration to the position managing apparatus through a foreign network by position registration conforming to host-based mobility. In mobile node and position managing apparatus, a plurality of routes passing through the home link and the foreign link are established. Accordingly, when the mobile node has the plurality of transceivers, it can simultaneously connect to the home link and the foreign link through respective transceivers, to perform communication.
Claims9
A communication system including:
- a mobile communication terminal including a plurality of transceivers and connecting through the transceivers to a home link that is constructed of a network performing network-based mobile management and a foreign link;
- and a position managing apparatus for managing a position of the mobile communication terminal, wherein
- the mobile communication terminal includes a position registering means for registering positional information thereof in the network to which the mobile communication terminal connects, into the position managing apparatus,
- the position managing apparatus includes:
- a packet transmitting and receiving means for receiving a packet addressed to the mobile communication terminal and transmitting a packet to be transmitted from the mobile communication terminal;
- a packet destination determining means for determining a destination of the packet from the packet received by the packet transmitting and receiving means;
- and,
- a positional information storing means for storing the positional information registered by the position registering means in association with the mobile communication terminal, and,
- the packet transmitting and receiving means determines a position of a receiver as the destination determined by the packet destination determining means, from the positional information storing means to transmit the packet.
A mobile communication terminal including a plurality of transceivers and connecting through the transceivers to a home link that is constructed of a network performing network-based mobile management and a foreign link,
- wherein
- the mobile communication terminal is assigned with a home address, and performs communication based on
- an address storing means for storing an address of a router to which the mobile communication terminal connects in a home link and an address acquired by the mobile communication terminal in a foreign link, in association with a home address of the mobile communication terminal,
- a route determining means for determining a route of communication,
- a selecting means for selecting an address associated with the home address of the mobile communication terminal stored in the address storing means, in accordance with a network through which the communication route determined by the route determining means passes, and the address selected by said selecting means.
A position managing apparatus for managing the position of a mobile communication terminal individually connected to a home link that is constructed of a network performing network-based mobile management and a foreign link, comprising:
- a positional information storing means for storing positional information of the mobile communication terminal;
- a means for transmitting and receiving a packet addressed to the mobile communication terminal and a packet transmitted from the mobile communication terminal;
- and,
- a packet destination determining means for determining a destination of a packet, from the packet received by the packet transmitting and receiving means,
- wherein
- the packet transmitting and receiving means determines a position of the destination determined by the packet destination determining means, from the positional information storing means and transmits the packet.
