In a system in which a reception (paging) cycle is defined by the number of frames, even if the length of the frames is changed, the power consumption of a mobile station (MS) and a delay in the response at the time of incoming are maintained by changing the paging cycle so that the paging cycles become equal in a time unit. The mobile station for receiving the signal from a wireless base station for each cycle defined by the number of frames to detect an incoming notification has a measurement unit for detecting a change in the frame length of the received frames, a cycle changing unit for, if the change is detected, increasing or decreasing the number of frames which defines the cycle, and an incoming notification monitoring unit for receiving the signal from the wireless base station in accordance with the cycle changed by the cycle changing unit. |
