Network optimization method and device and computer readable storage medium

The embodiment of the invention provides a network optimization method and device and a computer readable storage medium, and the method comprises the steps: obtaining drive test data collected at a plurality of sampling points, the drive test data comprising reference signal receiving power, signal to interference plus noise ratios and latitude and longitude information of a main service cell and an adjacent cell corresponding to the sampling points; performing problem road section extraction on the sampling points according to the road test data to obtain at least one problem road section; and determining a to-be-optimized cell based on the problem road section, and adjusting beam parameters of the to-be-optimized cell according to a preset strategy. Thus, the problem road section is determined according to the road test data of the sampling points, then the cell needing network optimization, namely the interference cell for the problem road section, is determined based on the problem road section, and the
