【摘要】：GSM(Global System For Mobile Communication)是第二代移動(dòng)通信的典型代表,目前擁有的用戶最多。GSM的運(yùn)行離不開其基站的正常工作。因此,基站維護(hù)工作是運(yùn)營商考慮重要問題之一�；揪S護(hù)的首要前提是對基站的工作狀態(tài)進(jìn)行測試分析。目前,已有的測試設(shè)備存在一定的局限性。測試方式方面:測試過程影響基站的正常工作;控制方式方面:測試控制方式是基于單機(jī)版的,不能夠?qū)崿F(xiàn)測試設(shè)備的遠(yuǎn)程控制、多人同時(shí)控制;應(yīng)用軟件功能方面:測試界面的親和力不足、數(shù)據(jù)存儲(chǔ)能力不強(qiáng)等。鑒于基站測試工作的重要性和已有測試設(shè)備存在的不足,團(tuán)隊(duì)研發(fā)了基于軟件無線電平臺(tái)的GSM基站測試儀。在測試儀研發(fā)過程中筆者的主要任務(wù)是:設(shè)計(jì)基站接收機(jī)靈敏度和發(fā)射機(jī)發(fā)射功率的測試方案;完成測試儀數(shù)據(jù)處理軟件的設(shè)計(jì)和實(shí)現(xiàn)。首先,本文對GSM通信系統(tǒng)的基本原理做了闡述,并對現(xiàn)有的基站測試設(shè)備和相關(guān)測試技術(shù)做了分析對比。在此基礎(chǔ)上,對基站接收機(jī)靈敏度和發(fā)射機(jī)發(fā)射功率的測試方案進(jìn)行了設(shè)計(jì),為測試儀測試模塊的實(shí)現(xiàn)提供理論指導(dǎo)。其次,在測試儀研發(fā)依托的軟件無線電平臺(tái)上搭建LASP環(huán)境,使得無線電平臺(tái)可以作為網(wǎng)絡(luò)服務(wù)器。從而實(shí)現(xiàn)測試儀的遠(yuǎn)程控制、多人控制方式,完成測試儀控制方式的拓展。在LASP環(huán)境的基礎(chǔ)上設(shè)計(jì)和實(shí)現(xiàn)數(shù)據(jù)處理軟件,該軟件主要包含數(shù)據(jù)處理接口、數(shù)據(jù)存儲(chǔ)、測試界面等模塊。最后,進(jìn)行了測試儀的場景實(shí)測,對測試儀測試模塊的功能、測試儀控制方式、測試儀數(shù)據(jù)處理軟件的功能和整體測試性能進(jìn)行了測試。測試結(jié)果表明,測試儀可以實(shí)現(xiàn)靈敏度和發(fā)射功率的測試,測試儀支持遠(yuǎn)程、多人同時(shí)控制,數(shù)據(jù)處理軟件工作穩(wěn)定。本文撰寫依托的GSM基站測試儀采用無線測試方式,不影響基站的正常工作。同時(shí)測試儀可以作為網(wǎng)絡(luò)服務(wù)器,實(shí)現(xiàn)測試儀可以通過網(wǎng)絡(luò)進(jìn)行遠(yuǎn)程控制和多人同時(shí)控制,拓展了測試設(shè)備陣營的控制方式。在應(yīng)用功能上,測試儀支持測試數(shù)據(jù)的存儲(chǔ)和歷史數(shù)據(jù)的查詢,改善已有測試設(shè)備在測試數(shù)據(jù)后續(xù)處理能力單一的弊端。該測試儀豐富了基站測試產(chǎn)品的種類,將在GSM基站性能測試中起到一定的作用。
[Abstract]:GSM(Global System For Mobile communication is a typical representative of the second generation mobile communication. Base station maintenance is one of the most important issues for operators to consider. The primary premise of base station maintenance is to test and analyze the working state of base station. The existing test equipment has some limitations. Testing methods: the test process affects the normal work of the base station; the control mode: the test control method is based on the single machine version, and can not realize the remote control of the test equipment. Multi-person simultaneous control; application software function: lack of affinity of test interface, data storage capacity, etc. In view of the importance of base station testing work and the shortcomings of existing test equipment, The team has developed the GSM base station tester based on the software radio platform. The main task of the author is to design the test scheme of the base station receiver sensitivity and transmitter transmission power; First of all, this paper describes the basic principle of GSM communication system, and analyzes and compares the existing base station test equipment and related test technology. The test scheme of base station receiver sensitivity and transmitter transmission power is designed, which provides theoretical guidance for the realization of test module. Secondly, the LASP environment is built on the software radio platform based on which the tester is developed. The radio platform can be used as the network server to realize the remote control of the tester, the multi-person control mode, and the extension of the control mode of the tester. Based on the LASP environment, the data processing software is designed and implemented. The software mainly includes data processing interface, data storage, test interface and so on. Finally, the scene of the tester is measured, the function of the test module and the control mode of the tester are analyzed. The function of the data processing software and the overall testing performance of the tester are tested. The test results show that the tester can realize the test of sensitivity and transmission power. The data processing software works stably. The GSM base station tester, which is based on this article, adopts the wireless test method, and does not affect the normal work of the base station. At the same time, the tester can be used as a network server. The tester can be controlled remotely and simultaneously through the network, which extends the control mode of the testing equipment camp. In the application function, the tester supports the storage of test data and the query of historical data. This instrument enriches the variety of base station test products and will play a certain role in GSM base station performance testing.
