in the same direction and having different transmission reception frequencies one cdma wireless base station control device 102 is installed for a plurality of cdma wireless base station devices 101 and executes wireless resource management including handover control for the cdma wireless base station devices 101 managed by the control device 102 the mobile stations 105 to 107 are located within the cells 103 and 104 and perform communication relatively close to the cdma wireless base station device 101 the mobile station 108 is moving toward the boundary from the center of the cell 103 and downloads a downlink image or the like at a high rate by ip packets 0021 fig2 shows an example of a temporal change in transmission power from the cdma wireless base station device 101 to the mobile stations 105 106 and 108 in a situation as shown in fig1 in fig2 the total transmission power threshold to all the mobile stations in this cell is 200 processing when the transmission power exceeds the total transmission power threshold of 200 will be explained with reference to fig3 in the cdma wireless base station device 101 a monitoring unit 14 a of the baseband processing unit 14 calculates and monitors a total transmission power in a given cell step s 1 a determination unit 16 a of the control unit 16 determines whether the total transmission power output from the monitoring unit 14 a continuously exceeds the maximum total transmission power threshold of 200 for a predetermined time or more steps s 2 and s 3 if u201c yes u201d in step s 2 or s 3 the control unit 16 sequentially extracts in a descending order for mobile stations a 1 resources which transmit data to.
