ABSTRACT:
A radio channel control method for a narrow-zone mobile communication system in which a plurality of base stations share a plurality of channels and each selects any of the channels for setting up a call independently of the others, e.g. a portable telephone system or a cordless telephone system. Installed in each of all the base stations are transceiver, free to use all the channels, a device capable of indentifying channels on which radio waves have reached the own station based on reception sensitivity, a device for selecting a channel, a device for transmitting a pilot signal and others, and a device for setting up a call. The channel for a pilot signal is adequately changed to shorten a duration of cochannel interference. Connection of multiple base stations to a single mobile station is eliminated by causing each base station to add to the pilot signal identification data which is particular to the base station.
