【摘要】：我国电信业成功重组后,三大移动运营商都具有开展电信全业务的资格与能力。为保证在未来竞争中获取更大优势,运营商们纷纷推出了丰富的3G业务。因为重要的3G商业用户多集中于室内,所以,良好的室内网络覆盖是移动运营商发展新用户、留住老用户的重点与关键。基于此,本文选取中国移动公司的TD-SCDMA网络的室内覆盖解决方案为研究课题,对其进行了详细的理论与应用研究。基于TD-SCDMA室内分布系统建设的特点以及室内无线信号传播环境的特征,结合地铁和高校应用的场景案例,本文详细地论述了TD-SCDMA室内覆盖系统的建设流程与策略。为中国移动公司TD-SCDMA室内网络建设提供了相应的理论基础与解决方案。论文的主要研究工作有： (1)明确了TD-SCDMA室内分布系统建设的目的；研究了TD-SCDMA室内无线传播环境的特点,并建立了相应的传播模型；给出了TD-SCDMA室内分布系统的四种接入方式；确定了TD-SCDMA室内分布系统建设的设计流程。详细讨论了TD-SCDMA室内覆盖常用组网方案与多网合一室内分布系统的设计。 (2)选取北京地铁与沈阳体育学院这两个典型的TD-SCDA室内应用场景为案例,分析了地铁与高校两个应用场景的特征,并对相应的TD-SCDMA室内分布系统的建设进行了详细说明。 (3)解决方案采用TD-SCDMA各种先进技术与组网理念,解决了TD-SCDMA室内覆盖的问题。
[Abstract]:After the successful reorganization of China's telecom industry, the three major mobile operators have the qualification and ability to carry out the full service of telecommunications. In order to ensure a greater advantage in the future competition, operators have launched rich 3G services. Because most of the important 3G commercial users are concentrated indoors, good indoor network coverage is the key for mobile operators to develop new users and retain old users. Based on this, this paper selects the indoor coverage solution of TD-SCDMA network of China Mobile Company as the research topic, carries on the detailed theory and the application research to it. Based on the characteristics of indoor distribution system construction of TD-SCDMA and the characteristics of indoor wireless signal transmission environment, this paper discusses the construction process and strategy of TD-SCDMA indoor coverage system in detail. It provides the corresponding theoretical foundation and solution for TD-SCDMA indoor network construction of China Mobile Company. The main research work of this paper is as follows: 1) the purpose of TD-SCDMA indoor distribution system is defined, the characteristics of TD-SCDMA indoor wireless communication environment is studied, and the corresponding propagation model is established, and four access modes of TD-SCDMA indoor distribution system are given. The design flow of TD-SCDMA indoor distribution system is determined. This paper discusses in detail the common networking scheme of TD-SCDMA indoor coverage and the design of multi-network-in-one indoor distribution system. 2) two typical TD-SCDA indoor application scenes, Beijing Metro and Shenyang Institute of physical Education, are selected as examples to analyze the characteristics of the two application scenes of subway and university, and the construction of the corresponding indoor distribution system of TD-SCDMA is explained in detail. The solution adopts various advanced technologies and networking concepts of TD-SCDMA to solve the problem of TD-SCDMA indoor coverage.
