PURPOSE:To reduce the frequency of occurrence of a failure of a call and to improve the servicability to the user by setting a radio line with a stationary radio equipment of other radio zone if the setting of line with a stationary radio equipment of a radio zone is failed in the case of making a call while storing at least two radio zones. CONSTITUTION:A mobile radio equipment 3a is located at a location where radio zones 51, 52 are overlapped and stores the radio zones 51, 52 as the radio zones to which the mobile radio equipment belongs. In this case, when the mobile radio equipment 3a makes a call, e.g., a stationary radio equipment 41 is selected and the mobile radio equipment sends a call signal 1a including an identification signal of the stationary radio equipment 41. The stationary radio equipment 41 receiving the signal 41a sends a channel designation signal. Thus, if a designated speech channel is busy, the mobile radio equipment 3a sends a call signal 1b including an identification signal of other stationary radio equipment 42 after a prescribed time (t) elapses. Thus, the frequency of the occurrence of a failed call is reduced and the servicability to the user is improved. |
