Abstract
A mobile station in a cellular communication system applies a cell monitoring mode in which signals from base transceiver stations are received to determine which of the base transceiver stations is to be selected by the mobile station as a serving base station, the mobile station including a movement detector and a controller for activating application of the monitoring mode when the mobile station is detected to be in motion and for de-activating application of the monitoring mode when the mobile station is detected to be stationary, wherein the movement detector comprises an estimator estimating a current signal quality level of a received signal and a processor determining a value of a parameter which is related to a variance of the current signal quality level from an average value of the received signal quality level and to determine if the value of said parameter is greater than a threshold value.
