摘要

When an IP packet is transmitted to a mobile terminal (801), a home agent (401) interrupts the IP packet and transfers the interrupted IP packet to a foreign agent (501) being at a present location by the tunneling method. The home agent (401) monitors communication qualities such as maximum transfer rates and throughputs of connections discriminated from each other by combinations of source IP addresses, destination IP addresses, source port numbers, destination port numbers, and the like.
