Abstract
A method and an apparatus are disclosed for controlling a radio telephone system comprising a single master apparatus connected to a subscriber line and a plurality of radio telephone sets connected to the master apparatus by way of radio channel. When a call origination operation is made by one of the radio telephone sets, a call originating signal is sent to the master apparatus from the call originating radio telephone set. In response to the call originating signal, the master apparatus switches its radio channel to an idle speech channel, and sends a channel designating signal representing the idle speech channel to the plurality of radio telephone sets including the call originating radio telephone set so as to switch the radio channels of the radio telephone sets which have received the channel designating signal to the idle speech channel.
