Method for controlling the average power transmitted by a base radio station of a mobile network, comprising the steps of: a) acquiring and processing the power value actually transmitted by the base radio station (Ptxavg_24hour_trasmitted) and data relative to the base radio station traffic, both of them in a plurality of time instants throughout each elapsed day, to generate and store historical data; b) providing a maximum threshold value of daily average power (P24_threshold) transmittable by the base radio station; c) providing a Power Watcher algorithm allowing to control the transmitted average power; d) using the Power Watcher algorithm to detect the average power value actually transmitted by the base radio station (Ptxavg_24ore_transmitted) in real time from the time instant at the beginning of the current day; e) processing by the Power Watcher algorithm historical data and the average power value actually transmitted by the base radio station (Ptxavg_24hour_trasmitted) in real time, to calculate an estimated average power value which will be transmitted by the base radio station during the rest of the day (Ptx_estimated) according to the trend of historical data, the rest of the day comprising the time period between the present instant of real time detection and the end of the current day at 24:00; f) calculating by means of the Power Watcher algorithm the average power actually transmitted by the base radio station (Ptxavg_24ore_trasmitted) up to the time of real time detection; g) limiting by the Power Watcher algorithm the power transmitted by the base radio station during the rest of the day when the sum of the estimated average power value which will be transmitted by the base radio station during the rest of the day (Ptx_estimated) with the average power value actually transmitted by the base radio station (Ptxavg_24hour_trasmitted) until the real-time detection time instant overcomes the maximum threshold value of daily average power (P24_threshold). a) acquiring and processing the power value actually transmitted by the base radio station (Ptxavg_24hour_trasmitted) and data relative to the base radio station traffic, both of them in a plurality of time instants throughout each elapsed day, to generate and store historical data; b) providing a maximum threshold value of daily average power (P24_threshold) transmittable by the base radio station; c) providing a Power Watcher algorithm allowing to control the transmitted average power; d) using the Power Watcher algorithm to detect the average power value actually transmitted by the base radio station (Ptxavg_24ore_transmitted) in real time from the time instant at the beginning of the current day; e) processing by the Power Watcher algorithm historical data and the average power value actually transmitted by the base radio station (Ptxavg_24hour_trasmitted) in real time, to calculate an estimated average power value which will be transmitted by the base radio station during the rest of the day (Ptx_estimated) according to the trend of historical data, the rest of the day comprising the time period between the present instant of real time detection and the end of the current day at 24:00; f) calculating by means of the Power Watcher algorithm the average power actually transmitted by the base radio station (Ptxavg_24ore_trasmitted) up to the time of real time detection; g) limiting by the Power Watcher algorithm the power transmitted by the base radio station during the rest of the day when the sum of the estimated average power value which will be transmitted by the base radio station during the rest of the day (Ptx_estimated) with the average power value actually transmitted by the base radio station (Ptxavg_24hour_trasmitted) until the real-time detection time instant overcomes the maximum threshold value of daily average power (P24_threshold).
