Abstract:
In a digital mobile radio system including frequency division and time division radio resources in the form of frames of time slots at radio frequency carriers, which system comprises at least one radio base station and a plurality of mobile radio stations, a power consumption reduction method comprising the following steps, when a mobile radio station is in a dedicated mode,a) performing of power measurement by the mobile radio station, during a reporting period, of neighbour channel carriers of radio base stations covering cells which are neighbouring cells of the cell serving the mobile radio station, characterised in that the power consumption reduction method further comprises the steps of b) performing an optimal number of power measurements per frame as permitted by the radio frequency hardware of the mobile radio station so as to get meaningful measurement samples, c) non-evenly distributing the power measurements over the frames of the reporting period, and d) powering down the mobile radio station during time intervals which would have needed for carrying out power measurements if the power measurements per frame were evenly distributed over the frames of the reporting period.
