【摘要】 近年来,移动业务和互联网业务飞速增长,对人们的工作、学习和生活模式都发生了潜移默化的影响。作为“移动”和“互联网”这两个概念的交集,移动数据业务也逐渐发展起来。为满足这种需求的增长,各种各样的概念或解决方案应运而生。中国移动的GPRS网络正是为了满足用户日益增长的移动数据业务需求而建设的。同时,它也是第二代向第三代的过渡方案,可以为3G提供各方面的经验。本文主要讨论的是以天津移动的GSM/GPRS网络为平台,采用GPRS方式,通过特种行业终端,服务于行业用户的、机器到机器(Machine To Machine,M2M)的数据传输业务。采取点对点或一点对多点的传输方式,实现末梢节点间、末梢节点同中心节点间的通信,可用于信息互传、数据互备、远程控制、远程监测等。可以为水利、电力、石油、环保、公安、金融等行业用户提供一种无线实时数据传输功能的解决方案。可广泛应用在行业监测、远程控制、团队协作、物流管理、无线POS等工作领域。作者从1999年月起在天津移动一直从事无线通信网络的工程建设工作,从2002年起,经过2年多的努力,从事利用GPRS进行特殊行业的无线数据传输工作,其间进行了多个项目的可行性研究、工程设计、项目招投标、工程建设实施,网络优化和问题分析及故障处理等大量工作,完成了天津移动第一个大型GPRS行业应用项目-天津电力路灯夜景照明系统,并率先在公共事业领域,主持完成了天津移动多个GPRS行业应用项目的工程建设工作。在此期间,我对基于GPRS网络进行数据传输及相关技术进行一些研究,并在工作中发现和解决了不少实际问题,请各位专家、学者批评指正。更多还原

【Abstract】 In recent years, Mobile services and Internet services have undergone substantialgrowth. They are posing increasingly profound impacts on the ways that peopleconduct their work, study and everyday life. Mobile data service, a new cross set ofservices that combine both Mobile and Internet concepts, is also start to surface.Various solutions have been put together in order to provide such services. GPRSnetwork of China Mobile, for example, is one of these solutions that meet theever-increasing demand for mobile data services from its customer. At the same time,it also serves as a transitional platform for the migration from 2G to 3G mobilenetworks, providing valuable experience for future upgrade. The subject of the paper is a special terminal based, customer-oriented, M2M(machine-to-machine) Data Transmission Service that is built upon the GSM/GPRSnetwork of Tianjin Mobile with GPRS technology. By using peer-to-peer ormulticasting transmission, this service enables the communication among end-pointsas well as between end-points and central office. It can be used to provide suchfunctions as bi-directional information transmission, pair-wise data backup,tele-control and tele-monitoring. With great potential in industrial monitoring,tele-control, group coordination, MRP and wireless POS, this service is a perfectreal-time wireless data transmission solution for various industries including waterconservancy, electric power, petroleum, environmental protection, public security andfinance. The author has been engaged in wireless communication networkimplementation and project management since 1999. While specialized in wirelessdata transmission projects for special industries using GPRS in recent 2 years, he hasgone through almost every step within the project life-cycle: starting from feasibilitystudy, engineering design, project bidding, network implementation and optimization,to problem analysis and trouble shooting. Tianjin Power Utilities City Night-SceneIllumination System, the first large-scale GPRS industrial application project byTianjin Mobile, was carried out successfully with the author active involvement. Healso played a leading role in multiple industrial GPRS application projects for TianjinMobile, with special focus in the public utilities industry. During this period of time,the author did further study in GPRS-network based data transmission and otherrelevant technologies, and was able to apply his study to solve problems encounteredin his projects.Opinions and suggestions from experts will be deeply appreciated bythe writer.更多还原
