Abstract
A network system implements paging control in which the control apparatus, upon receiving a packet destined for a mobile terminal, transmits a paging notification packet to a paging area of the mobile terminal, so as to obtain location information of the mobile terminal and to determine a transfer destination of a received packet. The control apparatus is configured to transmit the paging notification packet to a plurality of router devices included in the paging area. Each of the plurality of router devices is configured to transmit a received paging notification packet to a plurality of access points by multicasting. Each of the plurality of access points is configured to transmit a received paging notification packet to the mobile terminal through a link connection by multicasting, when it is judged that an IP address in the paging notification packet is a predetermined IP address.
