Abstract
When receiving a packet sent thereto from a mobile terminal that is a sending source, a subscriber packet exchange apparatus encapsulates the packet with a multicast address without acquiring information on a routing area in which another mobile terminal that is a destination is currently located from a home location register, and routes the packet to another subscriber packet exchange apparatus that manages the routing area in which the destination mobile terminal is currently located. As a result, the moving object IP packet communication system can carry out the transmission of data packets between the source and destination mobile terminals while reducing the transfer delay.
