The invention discloses a base station energy saving apparatus and method. A compensation antenna is arranged in a multi-sector base station, and the multi-sector base station comprises multiple directional antennas; in case of a non-energy-saving state, the compensation antenna is closed; and in case of an energy-saving state, the multi-sector base station closes other directional antennas apart from a first directional antenna and puts the compensation antenna into service, and the compensation antenna and the first directional antenna provide services to activated users in the whole covering area of the multi-sector base station. According to the base station energy saving apparatus and method, the compensation antenna can be put into service, a covering carrier frequency is used by one antenna, the energy saving efficiency is higher, a base station can realize reduction of energy consumption in a certain period or in a loading condition, the network maintenance cost is decreased, and the possibility that network performance is worsened when an energy saving function is started is reduced.
Description
technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a base station energy saving device and method. Background technique [0002] Currently, the energy consumption of base station equipment accounts for 90% of the energy consumption of the entire mobile network equipment. The energy consumption of the radio frequency part of the antenna exceeds 43% of the energy consumption of the entire base station equipment. Therefore, how to effectively reduce the energy consumption of the radio frequency part of the base station antenna is an important issue faced by operators and equipment manufacturers. [0003] At present, one of the main ways to save energy in the radio frequency part is to turn off the time slot, carrier or even turn off the power amplifier (Power Amplified, PA). The impact of closing the time slot and carrier on the network is relatively small, but in the actual test process Among them, the energy...
