COMMUNICATION SYSTEM, MOBILE COMMUNICATION TERMINAL AND POSITION MANAGING APPARATUS

摘要

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.

主权项

1. 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.
