Therefore, in the statistics, only the number of times that the LTE network occupying each cell requests data from the base station, which is hereinafter referred to as the number of sampling points, is concerned. That is to say, according to the collected MR data, the total number of sampling points of data requested by the LTE network occupying each cell to the base station within a preset time period and the TADV sampling value corresponding to each sampling point are counted, where the TADV sampling value can be understood as the time advance of the data requested by the UE user to the base station through the LTE network. The smaller the time advance TADV sampling value of a UE user requesting data from the base station indicates that the UE user is closer to the base station, and conversely, the larger the time advance TADV sampling value of a UE user requesting data from the base station indicates that the UE user is farther from the base station.
Through the collected MR data, the total sampling point number of data requested by each cell to the base station through the LTE network and the TADV sampling value corresponding to each sampling point are counted in the preset time period, the LTE network coverage concentration of each cell can be obtained through calculation and analysis of the TADV sampling point number and each TADV sampling value, and then the capacity of the LTE network is optimized.
