Abstract:
The current drawn by a wireless communications device that is configured to periodically scan control channels can be reduced by reducing the number of control channels to be scanned. The relative strengths of a serving cell control channel and the relative strengths of neighboring cell control channels are determined and the scanning of neighboring cell control channels is discontinued if the communications device is not moving and the signal strength of the serving cell is above a threshold value selected to provide a signal level at which data on a control channel can be reliably recovered.
