【摘要】 随着现代通信技术的不断进步，移动通信系统在近年来取得了长足发展。一方面，在激烈的市场竞争彤势下，中国的移动通信系统的容量呈现飞速发展，系统向着人容量、广覆盖及高质量方面发展；另一方面，系统也在向着数据化、智能化及多媒体化的方向发展，随着第三代移动通信技术的实现和移动通信与互联网的融合，未来无线数据的传输速率将达到2Mb/s，人类社会正向着移动信息时代迈进。第三代移动通信系统是一种能提供多种高质量业务类型的，能实现全球无缝覆盖的通信系统。该系统具有能进行全球漫游，能以小型便携式终端在任何时候、任何地点进行任何种类通信的特点，是移动通信系统由模拟到数字后再进一步发展的方向。TD-SCDMA作为中国自主知识产权的3G标准以其先进的技术特征和丰富多彩的业务类型吸引了广大的用户和运营商的关注。为了获得决胜3G移动通信的先机，中国移动通信有限责任公司正在积极准备TD-SCDMA建网工作，本文在对哈尔滨移动通信发展预测基础上结合城市无线传播环境分析，采用理论计算的方法，对基于TD-SCDMA技术的无线网络进行了具体的容量估算、覆盖范围确定、站址数量计算等一系列工作。在得出理论计算结果后，又应用网络规划软件对该结果进行了计算机模拟研究，考察了设汁系统在地理信息系统上的覆盖、导频干扰及服务质量情况，对规划的结果进行了优化和修正，最后得到哈尔滨移动通信分公司TD-SCDMA无线网络建设方案。本文的理论汁算结论为在城区173.8平方公里的范围内，满足通话及数据业务要求的TD-SCDMA基站数量为276个；计算机模拟仿真汁算的结论为该数量基站及其站址分布是可以满足工程实际要求的。本文提出了哈尔滨市未来无线网络发展的初步构想，为进一步的工程建设决策提供了依据。更多还原

【Abstract】 Along with the continuous development of modern communications technology, mobile communications system has obtained a rapid growth in recent years. The capacity of mobile communications system have been expanding quickly and higher capacity, higher coverage, higher quality are the target of the system. On the other hand, the mobile communications system is moving to the stage of combining the data services, multimedia services and intelligent services. The transmitting rate of radio data will reach the speed of 2Mb/s.The 3^rd mobile communications can provide many high quality services. Users can roam globally and can get any kind of communications in any time anywhere by mini terminals.TD-SCDMA has attracted the general users and the operation business attention as the China proprietary intellectual property rights 3G standard by its advanced technical characteristic and the richly colorful service type. In order to obtain the final outcome in 3G mobile communication , taking the initiative, China Mobile communication Limited liability company is preparing the TD-SCDMA constructing positively, this article unified the city wireless environment analysis to the Harbin mobile communication development forecasting,and used the method of theoretical calculation , based on the TD-SCDMA technology wireless network, this article has carried on a series of work such as the capacity estimate, the determination of cover scope, the quantity of station sites computation and so on. After obtaining the theoretical calculation results, also use the network planning software has conducted the computer simulation research to the results, inspected the designed system on the cover of geographic information system, the pilot frequency disturbance and the grade of service situation, has carried on the optimization and the revision to the results, finally obtained the Harbin Mobile communication Subsidiary company TD-SCDMA wireless network construction plan.Finally, the conclusions are that the sites number is 127 in urban areas of 55km²,and the amounts are also perfect in the computer simulation study. The paper has the reliability in constructing operation of 3^rd generation wireless network. It gives the solid foundation of next decision-making in network construction.更多还原
