Energy-saving method of wireless communication system

The invention discloses an energy-saving method of a wireless communication system, and the method is designed for solving the problem that the coverage of base stations is non-overlapped in the deployment of the wireless communication system. The wireless communication system is not always in a full load operation state, and carriers from the base stations are in an idle state in much time, so that one certain carrier is dynamically turned on/off according the change of loads of the base stations in the energy-saving process to save the energy consumption of the base stations for the carrier, thus the low-carbon energy-saving purpose is achieved.
