Abstract
A relay device acquires and stores address binding information indicating correspondence between a static communication address and a dynamic communication address of a mobile terminal which is linked to the relay device. The relay device also stores address binding information of other mobile terminals to which packets are sent from the source terminal. A management server stores the address binding information pertaining to the source terminal, and also stores the communication status information of the other mobile terminals with which the terminal is communicating. When the terminal terminates communication, the relay device and the server delete the address binding information pertaining to the source terminal by cooperating with each other.
