Step 105: base station general supply module opens or closes some power channel according to the control command that receives, in the hope of increasing or reduce power output;
Step 106: increase or reduce power accordingly received the control command of main control unit by the main control chip of administrative unit after; It specifically is some passage (output channel that comprises baseband processing unit that opens or closes related chip; The output port of radio frequency unit), between opening and closing, there is a kind of insurance mechanism can supply transition---park mode;
Step 107: given main control unit by administrative unit with adjusted information immediate feedback, base station general supply module also will up-to-date power allocation information (comprise the channel information of opening, closing, remain available horsepower etc.) in time reports main control unit.
Promptly realize the mutual of information and handled control and the adjustment that has also finally realized power by above-mentioned steps, also reached the purpose of energy-conserving and environment-protective.
The present invention is not limited to above-mentioned execution mode, anyly is familiar with this operator, is not breaking away from the spirit and scope of the present invention, all should drop within protection scope of the present invention.
