1. A method for analyzing and reducing pilot pollution, the method comprising:

  • collecting drive test data transmitted by cells using a drive test device, the drive test data obtained by marking at an interval of a certain period by the drive test device and detecting cell pilot identifiers and signal strength corresponding to each cell pilot identifier for the cells within range of the drive test device during the interval;

    generating a preprocessed map according to an engineering parameter table and the drive test data, wherein the preprocessed map comprises a cell distribution map and a pilot pollution distribution map, the engineering parameter table comprising longitude information, latitude information, and azimuth information;

    generating, for a target area to be analyzed in the preprocessed map, a map of abnormal cells of the target area according to the cell pilot identifiers and the signal strength corresponding to the pilot identifier of each cell in the target area, wherein the cell pilot identifiers correspond to cells on a one-to-one basis;

    generating radio optimization information for one or more target cells in the map of abnormal cells; and

    adjusting electrical and mechanical parameters of the one or more target cells in response to the radio optimization information in order to reduce pilot pollution in the target area.
