The embodiment of the invention discloses a method for analyzing pilot frequency pollution, and the embodiment of the invention also discloses a device for analyzing pilot frequency pollution. Wherein said method comprises: according to the actual project parameter table in the pre-import information and drive test data generation preprocessing map, this preprocessing map includes: cell distribution map and pilot frequency pollution distribution map, described actual engineering parameter table includes actual longitude , actual latitude and actual azimuth information, the drive test data is obtained by extracting the information of the test dot record, the test dot is obtained by the drive test equipment at regular intervals, and the test dot record includes the pilot frequency of the cell Information including the identification and the signal strength corresponding to the cell pilot identification; obtain selection information of the target area to determine the target area, and the target area is the area that needs to be analyzed in the preprocessing map; for the target area, generating a map of problematic cells in the target area according to the cell pilot ID in the drive test data and the signal strength corresponding to the cell pilot ID, where the cell pilot IDs correspond to cells one by one. Adopting the present invention has the advantages of avoiding playback of drive test data and watching playback connection, and high analysis efficiency.
Description
technical field [0001] The invention relates to the field of wireless communication, in particular to a pilot pollution analysis method and device. Background technique [0002] Pilot pollution is caused by the signal intensity received in the area is relatively high, and it is the first difficult topic to be solved in wireless optimization in the early stage of network construction, and a lot of manpower and material resources are required to solve it. [0003] Existing pilot pollution analysis methods generally include: [0004] According to the commonly used pilot pollution algorithm, the pilot pollution distribution map is output and displayed in the analysis software interface; the test data is played back in the analysis software, and the problematic cells causing the pilot pollution area are obtained through the signal connection received by the UE terminal. In the existing technology, when determining the problematic cell causing regional pilot pollution, it is nece...
