<p>PROBLEM TO BE SOLVED: To eliminate a packet loss caused by a destination terminal, that is moved to an area of other node unit and to prevent a node unit of a sender from keeping transmitting packets to a node unit, in the zone of which the destination terminal has been residing. SOLUTION: A receiver side not unit 20-3 transfers a received inter-node packet 81 to a node unit 20-4, in the zone of which the destination terminal is a resident directly or via other unit, or the node unit 20-4, in the zone of which the destination terminal is resident informs a node unit 20-3 (receiver side), in the zone of which the destination terminal has been resident about its own unit address [ADR6]. Furthermore, the receiver side node unit 20-3 or the node unit 20-4, in the zone of which the destination terminal is a resident informs the sender node unit 20-2 about a node unit address [ADR6] directly or via other device, in the zone of which the destination terminal is a resident.</p> |
