PROBLEM TO BE SOLVED: To perform a simultaneous awaiting with respect to services of each system, when a mobile station whose receiver has just one system exists in an area where radio zones of plural mobile communication systems overlap each other. SOLUTION: In this mobile communication method, when radio zones Za and Zb, which are formed by base stations (a) and (b) that belong to mobile communication systems A and B, overlap each other, a mobile station (c) which exists in this overlapped area switches receiving frequencies for each fixed time interval, separately receives a radio signal of different sending frequencies which are sent from each base station a and b, and by this, performs a waiting operation to systems A and B. In such a case, the station (b) receives a down radio signal which is sent from the station (a), detects its sending timing, and furthermore, control its own sending timing so that the sending period of a control signal which is included in its own down radio signal may not overlap one of a control signal, by the station a, based on the detected result. |
