Method for positioning working parameter problems and interference problems based on reported measurement data

Abstract

The invention relates to the technical field of communications and particularly relates to a method for positioning working parameter problems and interference problems based on reported measurement data. The invention is characterized in that the method comprises the following steps of: collection of the reported measurement data, establishment of an interference relationship matrix, judgment of antenna feed problems, positioning of abnormal interfering cells; subdivision of interfering problems and positioning of interference sources, and determination of out-off-band interference and other interferences, wherein the judgment of the antenna feed problems comprises the judgment of latitude and longitude problems, scene classification, abstract modeling of an antenna, calculating of the pathloss distribution of each cell, screening of cells with abnormal pathloss in each scene, cause determination of the cells with abnormal pathloss, and determination of the direction of the cell with the strongest interference signal according to the reported data; and the subdivision of the interfering problems and positioning of the interference sources comprise the processes of judging whether intermodulation interference exists or not, judging whether the interference is caused by a repeater or not, and judging whether the interference is caused by high configuration or not. The method has the advantages of reducing the workload for general survey, reducing the influence on a network, accurately positioning the interference sources, and reducing the workload for manual analysis.

Description

[technical field] [0001] The invention relates to the field of communication technology, in particular to a method for locating industrial parameter problems and interference problems based on measurement and reported data. [Background technique] [0002] With the increasingly mature development of GSM network, its optimization has entered into the fine optimization stage, so its industrial parameters (latitude and longitude, direction angle, downtilt angle, station height, etc.), interference problems (antenna electrical performance, repeater interference , out-of-band and other abnormal interference, etc.) has become more and more important. For these parameters, the current approach is: [0003] 1. Latitude and longitude: can only be found through on-site inspection; [0004] 2. Direction angle: For the cell where the antenna is reversed, it can be checked through the relationship between the neighboring cells, but for the accuracy problem, it can only be inspected by g...

Problems solved by technology

[0003] 1. Latitude and longitude: can only be found through on-site inspection;

[0004] 2. Direction angle: For the cell where the antenna is reversed, it can be checked through the relationship between the neighboring cells, but for the accuracy problem, it can only be inspected by going to each station of the base station;

[0012] 1) The efficiency is low, the inspection has no sense of direction, and problems can only be found through a large number of censuses;

[0013] 2) The workload is heavy: each worker must conduct on-the-spot investigation by engineering personnel to find out whether there is any problem;

[0014] 3) Affect the existing network: For issues such as antenna electrical performance, intermodulation performance, and repeater indicators, it is necessary to test and analyze problems one by one by disconnecting stations. For large-scale station disconnection analysis, it will have a greater impact on the network
