CDMA Network Optimization Analysis System

The system which calls Google Earth component object model application programming interface is based on the second development of Google Earth. CDMA network optimization analysis system is developed in Google Earth platform, using C Sharp computer language.This system contains the two big functions which are TOPN village analysis function and TD time buttress interference analysis function, TOPN village analysis mainly contains high to drop calls hours, high call failure hours, the average number of hours to drop calls every day, average call failure number, busy every day when failure high drop the calls hours and busy every day when high call failure number. The statistic result is displayed graphically in Google Earth. TD time buttress interference analysis function:according to the carrier interference table, the extent of the interference is showed in Google Earth with different color. In addition, parameters check function:contrast two RNC(Radio Network Controller) data configuration file, the file is classified into one-to-one and contrast for more. One-on-one:two separate documents data contrast. For more:the same filename file of more data file contrast. Data import function:import the base station basic information table and extract the latitude, longitude, azimuth, beamwidth, covering radius and village name, generating stations sector figure in Google Earth.In order to make the system has the extensive applicability and specific to the solution of the problem, have a large collection of personnel engaged in network optimization work experience. Inspiration, making the system of data analysis function can meet the general demand network optimization and individual special needs.The paper consists of six parts. Chapter1discusses research subject situation at home and abroad, research contents and purpose of research. Wireless network data analysis system based on Google Earth, data flow chart and data structure diagram are researched in chapter2. Chapter3is introducing database design, data dictionary design, entities related model and data table. Chapter4researches on realizing kinds of model, for example, application of TOPN analysis function. Chapter5is introducing system application and test result. Chapter6discusses looking to the follow-up system development.
