ABSTRACT:
A mobile terminal MN1according to the present invention judges, based on a router advertisement transmitted from an access router AR1, whether handover is to be executed between access points (APs) connected to the access router AR1, and transmits a link moving notification, which indicates that handover is executed under control of the access router AR1, to the access router AR1. Further, the access router AR1updates only routing information based on the received link moving notification.
