【摘要】：近年来，随着移动通信的飞速发展，手机已经逐渐成为一种现代通讯工具广泛应用于人民群众的日常生活，大多数的手机用户不是仅仅满足于良好的户外移动通信服务。现在多数建筑为采用高密材料且面积在数万平米以上的封闭式建筑，由于室内布局的复杂性，不利于传统宏站的深度覆盖，致使室内覆盖度不足，影响用户的业务感知。随着用户对网络质量关注度的不断提高，解决室内覆盖的问题已经箭在弦上。 针对室内覆盖的难题，发展建设室内分布是解决该问题的重要途径。与传统宏站结构相比，室内覆盖由信号源和室内分布系统两大部分组成。室内分布系统可以直接有效的作用于建筑物内部，，减少墙体的穿透损耗，能够更为全面的改善室内信号覆盖强度，提升室内通话质量，并通过话务下次扩大网络容量，缓解宏站的网络负荷。 作者主要从室内覆盖系统设计预评估、现网室分系统的优化等方面入手，介绍了室分系统的网络架构、发展趋势，并通过结合工作案例，从系统性能、覆盖能力、优化标准对各方面进行了系统的研究和分析，总结了室内覆盖系统的优化原则和室内覆盖系统的设计方案，研究了基于RRU新技术应用的室内覆盖系统与传统室内覆盖系统方案的优缺点，并通过在吉大一院的实际应用对比，验证了RRU技术方案的可行性及各种优点，论文最后根据理论分析，提出了分场景的RRU室内覆盖系统的方案建议。
[Abstract]:In recent years, with the rapid development of mobile communication, mobile phone has gradually become a modern communication tool widely used in the daily life of the people. Most mobile phone users are not only satisfied with good outdoor mobile communication service. At present, most buildings are closed buildings with high density materials and area of tens of thousands square meters. Because of the complexity of indoor layout, it is not conducive to the depth coverage of traditional macro stations, resulting in insufficient indoor coverage and affecting users' perception of business. With the increasing attention of users to network quality, the problem of indoor coverage has been solved. In view of the difficult problem of indoor coverage, the development and construction of indoor distribution is an important way to solve this problem. Compared with the traditional macro station structure, indoor coverage consists of two parts: signal source and indoor distribution system. The indoor distribution system can directly and effectively act on the interior of the building, reduce the penetration loss of the wall, improve the indoor signal coverage intensity, improve the quality of indoor communication, and expand the network capacity next time through telephone traffic. Relieves the network load of macro station. From the aspects of pre-evaluation of indoor coverage system design and optimization of current network room subsystem, the author introduces the network structure and development trend of room sub-system, and through the combination of work cases, from the system performance, coverage capacity, and so on, the author introduces the network structure and development trend of room sub-system. The optimization standard has carried on the systematic research and the analysis to each aspect, has summarized the indoor cover system optimization principle and the indoor cover system design plan, has carried on the systematic research and the analysis to the indoor coverage system. This paper studies the advantages and disadvantages of the indoor coverage system based on the new RRU technology and the traditional indoor coverage system, and verifies the feasibility and various advantages of the RRU technical scheme through the comparison of its practical application in the first Hospital of Jilin University. Finally, according to the theoretical analysis, the proposal of scenario-based RRU indoor coverage system is proposed.
