RADIO COMMUNICATIONS SYSTEM

摘要

A radio communications system which makes communications on a vacant channel selected from a plurality of frequency channels, and wherein a calling station sends a station discrimination code to specify a remote station together with vacant channel data that enables communication, and the remote station specified by the station discrimination code is shifted to the specified vacant channel thereby to make communication between the two stations. When the channel on which the two stations are communicating is busy, and when it is desired to use another channel, one station sends the date for another channel on the channel on which the communications are made, and the other station receives the data and continues the communications on the other channel.
