【摘要】：GSM(Global System For Mobile Communication)是第二代移动通信的典型代表,目前拥有的用户最多。GSM的运行离不开其基站的正常工作。因此,基站维护工作是运营商考虑重要问题之一。基站维护的首要前提是对基站的工作状态进行测试分析。目前,已有的测试设备存在一定的局限性。测试方式方面:测试过程影响基站的正常工作;控制方式方面:测试控制方式是基于单机版的,不能够实现测试设备的远程控制、多人同时控制;应用软件功能方面:测试界面的亲和力不足、数据存储能力不强等。鉴于基站测试工作的重要性和已有测试设备存在的不足,团队研发了基于软件无线电平台的GSM基站测试仪。在测试仪研发过程中笔者的主要任务是:设计基站接收机灵敏度和发射机发射功率的测试方案;完成测试仪数据处理软件的设计和实现。首先,本文对GSM通信系统的基本原理做了阐述,并对现有的基站测试设备和相关测试技术做了分析对比。在此基础上,对基站接收机灵敏度和发射机发射功率的测试方案进行了设计,为测试仪测试模块的实现提供理论指导。其次,在测试仪研发依托的软件无线电平台上搭建LASP环境,使得无线电平台可以作为网络服务器。从而实现测试仪的远程控制、多人控制方式,完成测试仪控制方式的拓展。在LASP环境的基础上设计和实现数据处理软件,该软件主要包含数据处理接口、数据存储、测试界面等模块。最后,进行了测试仪的场景实测,对测试仪测试模块的功能、测试仪控制方式、测试仪数据处理软件的功能和整体测试性能进行了测试。测试结果表明,测试仪可以实现灵敏度和发射功率的测试,测试仪支持远程、多人同时控制,数据处理软件工作稳定。本文撰写依托的GSM基站测试仪采用无线测试方式,不影响基站的正常工作。同时测试仪可以作为网络服务器,实现测试仪可以通过网络进行远程控制和多人同时控制,拓展了测试设备阵营的控制方式。在应用功能上,测试仪支持测试数据的存储和历史数据的查询,改善已有测试设备在测试数据后续处理能力单一的弊端。该测试仪丰富了基站测试产品的种类,将在GSM基站性能测试中起到一定的作用。
[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.
