Presuming a case of dividing a control plane of a base station controller (RNC) into an apparatus to control a cell resource and an apparatus to control each of mobile stations (MS), it is a problem to be solved to distribute a load on the mobile station controller by setting an additional mobile station controller due to an increase in subscribers. Cell control radio control servers (Cell control RCS) 7a, 7b are nodes to control common resources, e.g., radio common channel, cell spread code, electric power, etc., bound to a cell, mobile station control radio control servers (Serving RCS) 8a, 8b are nodes to control each of mobile stations (MS) 5, and movement control/location management of the mobile stations (MS) 5, radio individual channel control, etc. are performed. Cell control radio bearer server (Cell control RBS) 9a, 9b process traffic flowing on a radio common channel according to an instruction of the cell control radio control servers (Cell control RCS) 7a, 7b, and mobile station control radio bearer servers (Serving RBS) 10a, 10b process traffic flowing on the radio individual channel according to an instruction of the mobile station control radio control servers (Serving RCS) 8a, 8b.
