Problems solved by technology

[0003] The existence of these error messages often brings many problems to telecom operators’ base station construction and maintenance, user value-added business services, etc., and seriously affects the user experience of end users. Check and discover the location information, and then correct the location information of the suspicious base station
Obviously, it is cumbersome and unrealistic to search and correct the above information artificially

Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0015] The flowchart of the method involved in the present invention is as figure 1 shown, including the following steps:

[0016] (1) Base station information statistics in bill big data

[0017] For the bill data to be detected, count a certain number of days (for example, 1 month), and calculate the information of connecting to other two base stations before and after connecting the base station within a certain time range (for example, within a maximum of half an hour);

[0018] For each phone number in C, take the suspicious base station as the reference base station, and connect the reference base station at the time point t o For the reference time, search for the two base stations (b i , b j ), and set up base station set B, respectively extract the longitude and latitude information lo, la of these base stations;

Abstract

The invention discloses a method for discovering a position anomaly of a base station in user telephone bill big data based on a Ransac algorithm. The method comprises the following steps: for to-be-detected telephone bill data, making a statistics of information on other two base stations connected before and after the base station is connected within a preset time; selecting a preset number of base stations, and calculating the centers of the base stations and the distance between the centers of the base stations and the base stations as a parameter model adopted by the Ransac algorithm; andusing the parameter model to make a statistics of remaining base stations, according to a Ransac algorithm principle, if a newly obtained computing center parameter or a center distance parameter enables position information of the base station conforming to the parameter model to be lower than a certain threshold, then judging that the base station is a position abnormal base station. Accordingto the method for discovering the position anomaly of the base station in the user telephone bill big data based on the Ransac algorithm provided by the invention, by mining, analyzing and calculatingthe relevant information on other two base stations connected before and after the base station is connected in a user telephone bill, current suspicious base station information can be found out.

Description

technical field [0001] The present invention relates to a pattern recognition method, in particular to a method for discovering the abnormal position of a base station in user bill big data based on the Ransac algorithm. Background technique [0002] The big data of the telecom operator's call list contains the access base station information of the current call, and the base station information is manually entered by the base station installation and maintenance personnel in advance, tabulated and stored on the server side. These data often cause incorrect data entry due to the negligence and fatigue of the input personnel, so it is inevitable that they often contain a certain amount of wrong information about the location of the base station. [0003] The existence of these error messages often brings many problems to telecom operators’ base station construction and maintenance, user value-added business services, etc., and seriously affects the user experience of end user...
