Patent ID: 8359046

Claim:
A controller apparatus configured to implement paging control in which, when the controller apparatus receives a packet addressed to a mobile terminal, the controller apparatus transmits a paging notification packet to a paging area of the mobile terminal, so as to obtain location information on the mobile terminal and to determine a forwarding destination of the packet, the controller apparatus comprising: a processing language storing unit configured to store processing languages which can be handled at the controller apparatus; a receiving unit configured to receive from the mobile terminal a processing language in which an algorithm for forming the paging area is written; a paging area forming unit configured to determine whether the processing language received from the mobile terminal is stored in the process language storing unit; and a transmitting unit configured to transmit a response to the mobile terminal indicating that algorithm transmission is allowed when the paging area forming unit determines that the processing language is stored in the process language storing unit, wherein the receiving unit is configured to receive the algorithm for forming the paging area from the mobile terminal after the transmitting unit transmits the response to the mobile terminal, and the paging area forming unit is configured to form the paging area of the mobile terminal by the algorithm that is transmitted from the mobile terminal.
