Power consumption control method and system based on base station

The invention provides a power consumption control method based on a base station and a power consumption control system based on the base station. The power consumption control method comprises following steps: detecting the carrier use parameters of any one terminal served by the base station; judging whether the current data business quantity of the any one terminal is more than or equal to a preset threshold value; and determining whether to adjust the working voltage of the base station according to the judging result and the carrier use parameters, thus determining whether to control the power consumption of the base station. Through the technical solution of the invention, according to the load capacity of the base station, the carrier bandwidth combination can be changed and the carrier quantity can be reduced under a condition of not changing the data transmission rate; therefore, the working voltage of the base station can be adjusted according to the reduced carriers; the power consumption of the b
