Disclosed is a technique in which, when no reliability exists between a previous communication device and a destination communication device with respect to a mobile terminal, a context which is setting information needed for making a connection of the mobile terminal to a network is transferred at a high speed from the previous communication device to the destination communication device. According to this technique, before movement, a mobile terminal 101 is connected to a previous AR (access router) while, after the movement, it is connected to a destination AR 202 having no direct reliability with the previous AR 201. A relay AR 501 has the reliability with both the previous AR 201 and the destination AR 202 and relays connection therebetween. The previous AR 201 transmits a context through the relay AR 501 to the destination AR 202 before the movement of the mobile terminal 101. After the reception of the context, upon receipt of an active request for a connection from the mobile terminal 101 which has moved, the destination AR 202 authenticates the mobile terminal 101 by use of the context it has received.
