【摘要】：随着移动通信的普及,建筑物内的话务密度不断上升,室内的话务占总话务的比例越来越高。根据国外运营商的统计,70%以上的话务量来自室内,且数据业务绝大多数发生在室内,而室内恰恰是网络覆盖的薄弱环节。室内分布系统是针对室内用户群,用于改善建筑物内移动通信环境的一种覆盖方式,其原理是利用室内天线分布系统将移动基站的信号均匀分布在室内每个角落,从而保证室内区域拥有理想的信号覆盖。室内分布系统可以较为全面的改善楼宇内的通话质量,提高接通率,同时可以分担宏蜂窝话务,扩大网络容量,从整体上提高移动网络的服务水平,因此室内网络质量的好坏也成为用户选择运营商参考的标准。鉴于此情况,室内分布系统项目的优化工作也越来越受到运营商的重视。本文依据南京联通室分优化项目,结合南京联通WCDMA、GSM网络优化、细化测试规范和报告要求,应用项目管理理论分阶段明确了南京联通室内分布系统项目优化重点和关键点,对室内覆盖WCDMA、GSM系统的硬件和参数进行了优化,对室内覆盖WCDMA、GSM信号的效果进行了后评估。通过优化项目后评估,全面提升了南京联通楼宇内移动网络质量,优化了室分覆盖的楼宇,提高了室内信号覆盖水平和室内网络质量和数据业务速率,满足了室内用户对语音及数据业务的要求,提升了用户体验;同时对无室分覆盖的楼宇进行网络摸底,收集经纬度信息和标准7级地址,最终形成了南京楼宇移动网信息GIS数据库,为后期南京联通网络建设提供了依据。
[Abstract]:With the popularity of mobile communication, the traffic density in buildings is increasing, and the proportion of indoor traffic to total traffic is increasing. According to the statistics of foreign operators, more than 70% of the traffic comes from indoor, and most of the data services take place indoors, and indoor is the weak link of network coverage. The indoor distribution system is a kind of coverage method for the indoor user group, which is used to improve the mobile communication environment in the building. Its principle is to distribute the signals of the mobile base station evenly in every corner of the room by using the indoor antenna distribution system. In order to ensure that the indoor area has an ideal signal coverage. The indoor distribution system can comprehensively improve the quality of communication in the building and increase the connection rate. At the same time, it can share the macro cellular traffic, expand the network capacity, and improve the service level of the mobile network as a whole. Therefore, the quality of indoor network has become the standard for users to select operators. In view of this situation, the optimization of indoor distribution system project is paid more and more attention by operators. According to the project of Nanjing Unicom's room division optimization and the optimization of Nanjing Unicom's WCDMA GSM network, this paper clarifies the key points and key points of Nanjing Unicom's indoor distribution system project optimization by stages by using project management theory. The hardware and parameters of indoor coverage WCDMA-GSM system are optimized, and the effect of indoor coverage WCDMA-GSM signal is evaluated. Through the post-evaluation of the optimization project, the mobile network quality in Nanjing Unicom building is comprehensively improved, the building with room coverage is optimized, and the indoor signal coverage level, indoor network quality and data service rate are improved. It meets the requirements of indoor users for voice and data services, and improves the user experience. At the same time, it carries out network mapping of buildings without room coverage, collects longitude and latitude information and standard 7 level addresses. Finally, the information GIS database of Nanjing Building Mobile Network is formed, which provides the basis for the later construction of Nanjing Unicom Network.
