Problem to be solved: to accurately grasp the radio use situation of the cordless telephone apparatus at a simple and appropriate timing, and to ensure the necessary correspondence.In the parent machine BS1, the use of the time slot other than the time slot used by the self machine is detected by the RSSI detecting section 4422 in the frame of the communication channel used for communication with the slave machine for a predetermined period.The detection result of the RSSI 4422 is recorded in the radio use table 411.The calculation processing unit 412 calculates the radio utilization rate in the communication channel based on the stored data in the radio use status table 411, and outputs the calculated wireless utilization rate through the control signal processing unit 422 and the division / multiplexing processing unit 421.Diagram
