【摘要】 随着移动通信的迅猛发展,相应的带来了移动通信测试及维修市场的急剧增长。同时由于3G移动通信标准的竞争,3G网络的商业化还需假以时日,因此世界移动通信测试仪器市场仍以第二代移动通信测试为主。GSM数字移动通信系统作为第二代移动通信系统的代表,在我国的成功商用化使得我国对GSM数字移动通信系统设备的维护和优化需求也越来越大,而在移动通信测试仪器领域我国远远落后于国外,市场盼望质优价廉的国产移动通信测试设备。 针对这一现状,武汉理工大学信息工程学院和武汉市众友公司联合开发了本课题中的GSM数字蜂窝移动电话综合测试仪。它是按照测试移动台的要求设计的,并支持评价GSM900/GSM1800双频移动台性能所需的所有协议。通过对GSM系统空中接口的研究,测试仪的中央控制模块CPU处理器完成了GSM通信协议空中接口部分的Layer2(数据链路层),Layer3(网络层)功能,从而实现对移动台的入网登记、移动台主呼和基站主呼等功能并在此基础上提供对GSM移动台的测试和维修。

【Abstract】 With the impetuous growth of mobile communication system,it brings a rapid increase in mobile communication testing and repair market correspondingly.At the same time,because of the competition of the 3G mobile communication standards and long time’s waiting for the 3G system’s commercial use ,the mobile communication testing market still gives the leading position to 2G productions.To be the representation of 2G mobile system ,GSM’s successful using for business in china makes the demand for GSM testing equipment rising dramticallyo And so the maket expects good mobile communication testing equipments which are made in our country.According this actuality ,The Wuhan University of Technology and The Wuhan ZhongYou Company empolder the GSM Mobile Station Test Set in the project.lt is designed for the requirements of testing GSM mobile station and supports all the required protocol for estimating GSM900/1800 dual-frequency mobile station.According to the research to radio-interface of GSM,the central control module CCM’s CPU processor accomplishes the Layer2,Layer3 protocols’ function of the radio-interface part to implements the location updata to MS ,MS Call,BS Call,and then provides testing and service based on the link between MS and the test set.
