【摘要】：目前,TD-SCDMA的网络建设正在国内大规模地展开,由于移动通信无线环境复杂,存在很多各不相同的特殊场景,而对于这些特殊场景来说网络质量的提升又非常重要,所以如何针对这些环境复杂、场景多样的特殊情况提出相应的可行性综合解决方案成为大家关注的焦点。这些特殊场景与传统室内结构相比,布局和建设结构具有其特殊性,并且这些区域人流量大,忙时话务量多,话务密度高,对TD-SCDMA网络的容量和覆盖都有很高的要求,同时这些区域的建筑物通常规模大,形成了相对比较封闭的无线传播环境,对TD-SCDMA移动信号有很强的屏蔽作用,用户的终端无法正常使用,形成了移动通信的盲区和阴影区。由于人流密集,话务量高的特点,TD-SCDMA的网络建设不仅需要解决信号覆盖问题,而且还要解决容量问题。因此现有已建成网络并不能满足用户在热点区域对网络质量的要求,低覆盖率、低接通率、低话音质量、高掉话率等成为突出的网络问题。本论文立足于北京移动对热点区域TD-SCDMA网络建设的实际需求,与各省协作,针对热点区域(地铁、机场、会展中心)中遇到的关键问题及用户感知的实际需求进行深入研究,并结合TD-SCDMA可以应用的各种技术,在积极创新的基础上给出各类热点区域场景改造或新建TD-SCDMA室内覆盖系统的标准化解决方案,支撑北京移动TD-SCDMA网络建设。
[Abstract]:At present, the network construction of TD-SCDMA is being carried out on a large scale in China. Because of the complex wireless environment of mobile communication, there are many different special scenarios, and the improvement of network quality is very important for these special scenarios. Therefore, how to put forward the corresponding feasibility comprehensive solution for these complicated environments and diverse scenarios has become the focus of attention. Compared with the traditional indoor structure, these special scenes have their particularity in layout and construction structure, and these areas have a large flow of people, a lot of busy traffic, high traffic density, and high requirements for the capacity and coverage of the TD-SCDMA network. At the same time, the buildings in these areas are usually large, forming a relatively closed wireless transmission environment, which has a strong shielding effect on the TD-SCDMA mobile signal, the user terminal can not be used normally, forming the blind area and shadow area of mobile communication. Because of the characteristics of dense flow and high traffic, the network construction of TD-SCDMA not only needs to solve the problem of signal coverage, but also to solve the problem of capacity. Therefore, the existing network can not meet the needs of users in hot spots, low coverage rate, low access rate, low voice quality, high drop rate and so on become outstanding network problems. This thesis is based on the actual demand of Beijing Mobile for the construction of TD-SCDMA network in hot spot area. In collaboration with each province, this paper makes a deep research on the key problems encountered in hot spot area (subway, airport, convention and exhibition center) and the actual needs perceived by users. On the basis of active innovation, the standardized solution of TD-SCDMA indoor coverage system is presented based on various technologies that can be applied by TD-SCDMA, which can support the construction of TD-SCDMA network in Beijing Mobile.
