PURPOSE:To realize a system with high effective utilization of the frequency without same radio channel interference and adjacent radio channel interference or the like by supplying an idle slot of the time slot series in a radio channel already in use to a mobile radio equipment newly desiring the communication. CONSTITUTION:When a handset of a telephone set section 101 is hooked off, a call control signal outputted from the telephone set section 101 is sent through a radio channel CH1. A control signal (0.2-4.0H) and a communication signal CHi (4.5-45kHz) are accommodated in a time slot SDi (i=2, 3,..., n). However, signals in each time slot are arranged in time series and signals in plural time slots are never simultaneously fed to a radio transmission circuit. The transmission of the control signal is limited to the time slot SUn only in this way and sent in a burst and the signal is not sent in other time band, then no adverse effect is given to on other communication. |
