Research Of Traffic Distribution Based On Mobile User Location Estimation

With the development of mobile Internet,mobile user location based service(LBS)has been widely applied,the requirements to estimate the position of the mobile user are put forward.Based on the estimation of the mobile user's location,we can allocate the limited wireless resources reasonably,enable the system under the condition of the limited resources to provide the guarantee of quality of service as far as possible,so as to improve customer satisfaction.Therefore,it is necessary to study the positioning technology in cellular network and the distribution law based on the location of mobile users,so as to offer a better theoretical basis for the mobile user location based services.This paper involves the research topic on Huawei technologies co.LTD.,Cooperation projects,the purpose is to realize three-dimensional positioning of indoor and outdoor users in the mobile network environment.Based on the location results,the traffic distribution of the user group is studied.And then realize the mobile user location estimation based business distribution system under Windows platform.This paper describes the implementation process of the traffic distribution system based on the location estimation of mobile users.Design and implementation process is mainly divided into the establishment of off-line fingerprint database,online fingerprint matching process and the implementation of traffic distribution research project.Specifically including the study of the heuristic fingerprint matching rules to improve the positioning accuracy with the assist of geographic information system(GIS);the establishment of off-line fingerprint library is to establish the inverse 3D ray tracing model in the dense urban area based on the electronic map.On-line fingerprint screening is to filter out the matching fingerprint samples in the fingerprint database combined with heuristic matching rules.The study of traffic distribution mainly includes the hotspot cluster analysis on the current network user group.Finally,combining the above theory,we introduce the implementation of the traffic distribution system based on the mobile user location estimation with C + + programming language,geography information system and SQL Server database.Then we verified this system using WCDMA network test data.The results show that the traffic distribution system based on the location estimation of the mobile users can obtain a high accuracy of the estimation of the location of the mobile users.and based on the user location information to explore the distribution of the hot spots.
