[0002] With the large-scale deployment of communication base stations, the number of base stations continues to increase, and the energy consumption of communication networks is also rising. How to achieve intelligent energy conservation and emission reduction is imminent. Existing tower base stations will set up multiple carrier frequencies for mobile devices to access during operation. The number of these carrier frequencies is usually fixed and does not change with the number of mobile devices connected. This leads to a large number of idle carrier frequencies in certain periods of time, and the maintenance of idle carrier frequencies will lead to energy waste. Summary of the invention

[0011] S7: Adjust the number of carrier frequencies in each cell in the next period according to the number of devices accessing each cell in the next period.

[0012] As a preferred solution of the above solution, the heat value calculation formula is as follows:

[0016] As a preferred solution of the above solution, the internal heat value calculation formula is as follows:

[0017] h i =α*bu si +β*bu mi +γ*bu li
