Abstract

A method, device and system for regulating power consumption are provided in the embodiments of the present invention. A method for regulating power consumption includes: obtaining, by a base station, an application point and a configuration parameter; sending, by the base station, an indication message to a terminal according to the application point and configuration parameter; regulating, by the base station, the power consumption of the base station by using the configuration parameter at the application point; the configuration parameter comprises cell antenna information or system bandwidth information; the indication message instructs the terminal to use the configuration parameter at the application point. Under the condition that user'"'"'s normal communication is remained, the number of cell antennas or the cell bandwidth is dynamically changed. This reduces the power consumption of the network device.
