In realization process of the invention it has been found that cell power control mode of the prior art is cell-level,
The region that the RRU of same cell is covered and the region that a RRU each passage is covered are configured such that with same
Power.If the power configuration is too low, the overlay area higher to power requirement can be caused effectively to cover, if mistake
Height, strong jamming can be formed between each overlay area, and higher power is used for the relatively low region of those power requirements
Covering, will also result in the waste of resource.Power distribution mode of the prior art, it is impossible to solved while weak covering is avoided strong
The problem of interference.
On this basis, the embodiments of the invention provide a kind of Poewr control method, as shown in figure 1, this method includes：
Step S1, obtains the grouping information of user's input, and each RRU institutes that the grouping information is used in indicating cell are right
The packet answered.
Step S2, each RRU in cell is divided into by multiple packets according to the grouping information.
Step S3, obtains power configuration information, and the power configuration information is used to indicate each packet with being each packet
Corresponding relation between the power of configuration.
Step S4, according to the power of the RRU institutes overlay area in each packet of power configuration information configuration.
Here user refers to the user for having packet demand, such as network optimization personnel of operator etc..
It is right in Poewr control method provided by the invention（It is same）Each RRU in cell is grouped, and is different points
Different power is distributed in RRU institutes overlay area in group.Poewr control method and equipment are provided using the present invention, can be according to every
The covering conditions of demand in individual region, the power of each overlay area is separately controlled.So, can be higher to power requirement cover
Cover area（Such as smart antenna overlay area）The higher power of configuration, while the overlay area relatively low to power requirement（Such as
