Abstract:
1. A method of driving a mobile communication terminal in a cellular network, said method comprising: monitoring reception power levels between the mobile communication terminal and a number of base stations of the cellular network by a control unit of the mobile communication terminal at a predefined reception power level monitoring rate for each base station, intermittently monitoring timing information values for a number of base stations by the control unit, monitoring a drift of the timing information values for at least two of the base stations and a significant motion of the mobile communication terminal is deemed detected if at least one of the timing information values indicates a drift equal to or exceeding a given timing drift threshold, and reducing the predefined reception power level monitoring rate to a reduced reception power level monitoring rate for at least a number of the base stations as long as the motion of the mobile communication terminal is not a significant motion, wherein the monitored reception power levels are reported by the mobile communication device to the respective base stations at the desired reception power level monitoring rate and, if the reception power levels are monitored at the reduced reception power level monitoring rate, a previously measured reception power level is reported to the base station until a Previously presented reception power level has been measured, and wherein the significant motion of the mobile communication terminal is determined by either the monitored reception power levels or the drift of the timing information.
