<p>A radio-telephone system and method of operation. A code indicating a channel next available for communication is modulated on a marker channel. Radio-telephones scan to detect the marker channel and decode the identity of the next available channel. This channel identification is stored in a memory associated with the radio-telephone. To place or rereceive a call, the radio-telephone consults its memory to determine the next available channel and then switches to that channel. The arrangement eliminates operational problems associated with "camping" on the wrong channel and the long channel scan times associated with known systems and methods.</p> |
