1.3) arrived load period, the base band control module is calculated carrier wave and radio system and is crossed the average power separately of load period and calculate overload level separately according to overload threshold separately at this, if the overload level of carrier wave is lower than the overload level of its place radio system, then the overload level lifting with carrier wave is the overload level of its place radio system;
1.4) according to the overload level of each carrier wave, the base band control module is carried out the control of carrier power overload to it respectively; So just can utilize the control of existing carrier power overload to realize the power overload of radio system/whole radio frequency unit is controlled.
According to control method provided by the invention, the overload level of described carrier wave is corresponding one by one and consistent with the overload level of described radio system.
According to control method provided by the invention, described carrier power equals the power sum that interior each channel board of radio system reports all the carrier frequency sectors corresponding with this carrier wave.
According to control method provided by the invention, described carrier wave average power equals this to be crossed repeatedly described carrier power sum in the load period and crosses the described number of times that reports in the load period divided by this, and described radio system average power equals each carrier wave average power sum in this radio system.
According to control method provided by the invention, the method for grading control is adopted in the control of described carrier power overload.At situations such as calling, switching, bring to powers, different carrier wave overload levels are done different restrictions.
According to control method provided by the invention, described carrier power overload control hierarchy adopts the double threshold protection, prevents the table tennis overload.
According to control method provided by the invention, circulation controlling means is adopted in the control of described carrier power overload, cycle is judged the overload level of carrier wave, and when finding that carrier power reaches certain overload level, the continuation of controlling carrier power by modes such as restriction call, switching, bring to powers promotes.
According to control method provided by the invention, the overload level of described carrier wave is corresponding and consistent with the overload level of described radio system.
According to control method provided by the invention, described channel board can dispose one or more carrier frequency sector.
According to control method provided by the invention, described channel board can be one or more.
According to control method provided by the invention, described multi-carrier RF system can be GSM, CDMA2000, WCDMA or TDCDMA.
Forward power overload control method of multi-carrier radio frequency system provided by the invention, make the overload level of arbitrary carrier wave be greater than or equal to the overload level of radio system, thereby not only can carry out power control to carrier wave, and can carry out power control to whole radio frequency unit/radio system, the more effective excessive radio frequency unit that causes of system power of having avoided damages, and has guaranteed the stable and safety of system.
