The Design And Realization Of Embedded Mobile Communication Network Base Station Detector

With society's high speed development, the Location Base Services increases day after day in the daily life. With modern displacement telecommunication networks develop at full speed, the number of the mobile phone subscribers also increase with each passing day. At the same time, the need of the Location Base Services is also increasing.Because the technology limitation in the 2th-generation mobile communication network, it exist the certain defect in allocation accuracy, and this disadvantage brings certain error to the Location Base Services. But in order to provide higher accuracy Location service, we can collect the information of the mobile communication BTS in advance, such as CGI, field identity, and use many kinds of Localization evolutionary algorithm to adjust the error from the collecting data, so that we can provide the fine basis data for the Location Base Services.Above all, this thesis made a further study at the wireless communication theory of the 2th-generation mobile communication system with wireless communication terminal module, and found out the method of carrying out the feasibility technology which bases on the BTS's information detection. Through control wireless communication terminal module, we can detect the BTS informations. At the same time, this thesis made a further study at the allocation technology of the mobile communications network BTS, and also made different researches and comparisons in several kinds of allocation methods, such as the CELL ID allocation method, based on identity measurement allocation method and TOA/TDOA.According to the research of mobile communication module and AT dictate, we have designed and realized the information detective and collection of domestic GSM BTS, CDMA BTS and GPS. At the same time, unified the hardware design technology, designed and seeled a set of AT command for this system, provided the convenience for the software system development.Base on the requirements of base station detective, a embedded mobile communicate base station portable hand-help detector is modeled and designed after research and analysis to the ARM micro process unit embedded type hardware system module,mobile communication module and GPS module.Finally, the Mobile BTS Detector system is realized based on the design of this paper. And the detector passes the exam which is taken place in Guangzhou. The result of the test describes that the detector is able to detective the accurate relevant of the domestic GSM BTS, CDMA BTS and GPS efficiently. It does strongly play a positive role in actual utilizing to offer reliable base information to other systems which provide the location services.The Embedded Mobile BTS Detector improve a simple and effective solution for currently mobile location accuracy of the Location Base Service, with the larger significance of the application. ?...
