The invention provides a network working parameter optimization method based on a gradient descent method, which can improve the stability and accuracy of a calculation result of a derivative vector of working parameters. The method includes the following steps: obtaining a working parameter to be optimized; determining an overall coverage rate of all sampling points in a target area to be optimized according to the obtained working parameter to be optimized, wherein the overall coverage rate is equal to a mean value of the coverage effects that all the sampling points are covered, and the coverage effect that each sampling point is covered is a continuous value between [0, 1]; determining the derivative vector of the working parameter by using a continuous derivative finding rule based onthe overall coverage rate of all the sampling points; and determining an optimized working parameter based on the derivative vector of the working parameter that is determined. The scheme of the invention is applicable to the optimization operation of network working parameters.
Description
technical field [0001] The invention relates to the field of mobile communication, in particular to a method for optimizing network operating parameters based on a gradient descent method. Background technique [0002] The existing mobile communication network is dominated by cellular networks. By deploying multiple base stations in the network, these base station equipment are equipped with multiple (directional) antennas to transmit wireless signals in different directions to jointly achieve communication signal coverage in an area. In each base station, it generally includes 3 (there are 2-4 individual cases) radio frequency units and antennas, and each antenna has its own network operating parameters (referred to as industrial parameters), such as: azimuth, downtilt, launch power etc. [0003] Network planning and network optimization are important technical links in mobile communication networks. Network planning usually refers to the rough estimation and layout consi...
