【摘要】：随着移动通信网络建设的深入,无缝隙覆盖已经成为各大运营商网络覆盖的终极目标,对运营商来说,要建设“精品网络”,实现真正意义上的移动通信网络无缝覆盖,小区的深度覆盖是城区深度覆盖的重要内容和城市深度覆盖的最后一个难点,其重点解决室外宏站不能有效覆盖的区域。因此,如何解决居民小区的信号覆盖和网络容量,满足人们对城市小区高质量的覆盖,已经成为移动网络运营商日益关注的课题。本文通过描述不同场景无线传播环境的特点和覆盖需求的不同,以及用户对覆盖的期望不断提升以及每信道发射功率小、路径损耗大导致覆盖半径小等网络本身的特点,利用项目管理理论,将小区覆盖问题的解决过程分为系统方案设计阶段、风险分析阶段和风险控制阶段,研究了每个阶段的主要内容,所提出的风险控制策略,如导致弱覆盖、导频污染控制、切换问题的风险控制措施等,对于解决覆盖盲点、覆盖空洞问题并充分吸收这类区域的话务,缓解网络容量压力,最终提高网络的服务质量,提供了理论支撑。
[Abstract]:With the development of the mobile communication network, the seamless coverage has become the ultimate goal of the network coverage of the major operators. For the operators, the "fine network" should be built to realize the seamless coverage of the mobile communication network in the real sense. The depth coverage of the community is the important content of the depth coverage of the urban area and the last of the urban depth coverage. A difficult point is to solve the area that the outdoor macro stations can not effectively cover. Therefore, how to solve the signal coverage and network capacity of residential communities and meet people's high quality coverage of urban communities has become a topic of increasing concern for mobile network operators. This paper describes the characteristics and coverage of the wireless communication environment of different scenes. The requirements are different, and the users' expectation of coverage is continuously improved, the transmission power of each channel is small, the path loss is large and the coverage of the network itself is small. Using the project management theory, the solution process of the cell coverage problem is divided into the design phase of the system scheme, the risk analysis stage and the risk control stage. The main content of the stage, the proposed risk control strategies, such as the weak coverage, pilot pollution control, and the risk control measures of switching problems, provide theoretical support for solving the blind spot, covering the hole and fully absorbing the traffic in this kind of area, alleviating the network capacity pressure, and ultimately improving the network service quality.
