It is configured to manage each paging area.

 Since the mobile communication system 1 needs to manage the position of the mobile station 50 for each paging area, the mobile communication system 1 receives the area registration information transmitted from the mobile station 50 every time the mobile station 50 moves beyond the paging area. Then, the subscriber registration information of the mobile station 50 included in the area registration information and the paging area identification information for identifying the paging area where the mobile station 50 exists are associated and stored in the subscriber database. Configured to do.

 Then, in the incoming call processing for reaching the incoming information to the mobile station 50, the mobile communication system 1 that has received the incoming information addressed to the mobile station 50 transmitted from the network refers to the subscriber database and receives the received incoming information. The paging area associated with the subscriber identification information of the mobile station 50 included in the mobile station 50 is specified, and the incoming call information is simultaneously transmitted to the paging area.

As a result, in the conventional mobile communication system 1, since the paging area is formed by a plurality of sectors, the number of area registration processes due to the movement of the mobile station 50 is reduced, and the radio control device 30 and the base station of the mobile communication system 1 are reduced. The incoming information addressed to the mobile station 50 can be surely reached the mobile station while reducing the communication processing load of 40.
