【摘要】：随着城市化进程的不断加快,室内弱覆盖问题日益突出。一方面室分投资远远无法满足室内弱覆盖需求,另一方面部分居民小区等特定场所新建的宏站和室分被拆除的风险比较大,存在投资浪费的现象。因此,必须改变主要依靠新建室分解决室内弱覆盖的传统建设思路,寻找一种低成本、低风险且快速有效的建设方式。本文则针对室内区域网络弱覆盖的问题,尤其是企业等办公区域的网络优化,提出了基于FemtoAP的解决方案。首先针对高层室内覆盖问题,讨论了室内分布式系统、WLAN及Femto等三种技术方案,并从组网方式、成本及用户体验等方面进行了对比分析。由分析可知,Femto技术在面向小规模区域或集团、家庭客户,尤其是对容量需求小、重要的弱覆盖区或覆盖盲区具有较好的作用。其次通过对中国移动目前的TD制式(TD-SCDMA. TD-LTE)的网络结构和关键技术的分析,讨论了在中国移动网络下Femto的网络结构和及其关键技术。接着面临当前集团内用户对网络覆盖优化的需求日益迫切的局面之下,在给出了Femto企业应用方案,可以依托不同场景内的IP宽带接入,完全利用现有的宽带资源,同时为用户提供TD-SCDMA和WLAN接入信号。结合江苏移动制定的关于企业级Femto的设计规范,详细的介绍了安装条件、安装方式以及设计目标,并且重点针对写字楼、宾馆酒店、商业建筑等三种场景给出了方案设计细则。最后按照办公区和小区的场景给出了企业级Femto AP的测试情况,通过测试得出Femto对于网络优化的较好作用。
[Abstract]:With the development of urbanization, the problem of weak indoor coverage is becoming more and more prominent. On the one hand, the indoor investment is far from meeting the demand of weak indoor coverage, on the other hand, the risk of the demolition of the new macro stations and rooms in some residential areas and other special places is relatively high, and there is a phenomenon of investment waste. Therefore, it is necessary to change the traditional construction thought which mainly depends on the new building room to solve the weak indoor coverage, and to find a low cost, low risk and fast and effective construction method. In this paper, a solution based on FemtoAP is proposed to solve the problem of weak coverage of indoor area network, especially the optimization of office area. In this paper, three technical schemes of indoor distributed system, WLAN and Femto, are discussed firstly, and the comparison and analysis are carried out from the aspects of networking mode, cost and user experience. From the analysis, we can see that Femto technology plays a better role in small scale area or group, home customer, especially in weak coverage area or blind area with small capacity demand. Secondly, TD-SCDMA-TD-SCDMA-TD-SCDMA-TD-SCDMAthrough the current TD system of China Mobile. The network structure and key technologies of Femto in China Mobile Network are discussed. Then in the face of the increasingly urgent demand for network coverage optimization by users in the group, Femto enterprise application scheme is given, which can rely on IP broadband access in different scenarios and make full use of existing broadband resources. At the same time, TD-SCDMA and WLAN access signals are provided to users. Combined with the design specification of enterprise Femto made by Jiangsu Mobile, the installation conditions, installation methods and design objectives are introduced in detail, and the detailed design rules are given for three kinds of scenes, namely office buildings, hotels and hotels, and commercial buildings. Finally, according to the scene of office area and residential area, the test of enterprise Femto AP is given, and the result shows that Femto plays a better role in network optimization.
