Abstract
In a cellular mobile radio-telephone system, a hand-off procedure is implemented by use of idle voice channel transceiver at relay stations of cells contiguous the site of a mobile station. The receiving portion of each transceiver is provided with tuning circuitry permitting a detuning from a preassigned idle channel frequency to the present broadcast frequency assignment of the mobile station. A set of measurements of broadcast signal is made at the detuned idle channels to determine the cell of best signal. The mobile station is then handed off to the cell of best signal.
