The Research And Achievement Of Visualization For Mobile Communication Network

With the rapid development of mobile communication network, the data of mobile communication network has an explosive growth, so that it brings mobile communication network optimization a huge challenge. It is not appropriate for the staff to analysis the data via documents and tables any more, which takes much effort. Furthermore, as the relationship of data is more and more complex, it is very difficult to find the relationship by artificial way. The importance of mobile communication network optimization is obvious, and it is the target for the department of mobile communication network optimization to quickly find network problems and solve them.In this thesis, a big data visualization system for mobile communication network is proposed and implemented. In order to present data in the front-end, the visualization system should interact with databases frequently. While the enormous amount of data would influence the speed of data visualization. Two methods are proposed to improve the speed of data visualization. One method is to speed up data acquisition by adopting three technologies, which are establishing procedure connection pool, utilizing caches, and designing indexes and stored procedures according to the structure of the database table. In detail, a dynamic allocation for minimum number of connections in procedure connection pool is achieved, and web cache and data cache in database are designed when caches are utilized. The other method is to optimize the entire system, which includes the front-end optimization and back-end optimization. To optimize the front-end three methods are proposed. Firstly, refreshing of partial web pages is designed. Secondly, the HTTP request is reduced. Lastly, Java Script language is optimized to get a high performance. The back-end optimization mainly includes two kinds of methods. Firstly, the view states and its impact on system performance are discussed. Secondly, the string in C# language is optimized.A solution which is data visualization for mobile communication network is proposed according to the actual situation of mobile communication network optimization. In order to present mobile communication data on the map, firstly, the area of Zhuhai on the map is divided with grid. Secondly, the mobile communication network data is filled in the grid with cell-grid coverage algorithm. Lastly, the data and its grade through map and charts are presented.
