Design And Inpelement Mobile Phone Base Station Dataacquisition And Base Station Positioning System

Base station positioning is one of the commonly used mobile phone positioning way,due to low positioning speed and authorization limit become widely adopted method of positioning.But,base station positioning is affected by the signal coverage,and positioning accuracy is not high.Public security department in the arrest,search,tracking,positioning the criminals,the need to quickly locate target information,so the base station location will help the police locate the criminals.With the popularization and application of data mining algorithm,base with data mining function is data acquisition and positioning system,is of great significance to improve the public security organs to improve the work efficiency.We know according to the characteristics of the wireless communication base station signal in a specific location will have its specific performance,the specific performance is equivalent to the location of the fingerprint,so as long as mobile phone base stations in different position of related parameters are collected,and using the existing data analysis and statistics on the data mining technology,can form a base station location\"fingerprint\" library,when the need for positioning,as long as to master the related parameters in the target cell phone base station signal,can through the base station location \ "fingerprint\" library matching the query,analysis of target mobile location.Data acquisition and mobile base station positioning system based on this principle,by running in the mobile terminal data acquisition program and GPS latitude and longitude information parameters of base station signal acquisition,and uploaded to the base station data sample library,then by using the clustering algorithm based on density of base station data sample data repository for data mining,to learn a particular geographic location information of the base station signal parameters,and to save the results of the analysis to the base station location information database,to provide users with a high precision position information and quick response.At present mobile phone base stations data acquisition and positioning system with the police and the public security system internal VPN network and public security departments such as PGIS existing resources to fully mix,for the public security department provides the high quality of base station location services,the duty police position precision and response speed has reached the requirement of policing the base station location.
