【摘要】：调查数据显示,目前已有70%的移动通信业务量来源于室内系统。室内的电磁传播环境远比室外复杂。为保障室内网络的性能,提升用户体验,针对室内分布系统进行干扰分析和网络优化,对提高移动运营商的服务竞争力,具有重要意义。首先,针对室内分布系统不同场景的覆盖特性,对室内分布系统的干扰因素进行了研究。通过测试干放以及无源器件的互调指标,分析分布系统引入的有源设备、无源器件对网络的影响,找出干扰产生的原因并给出优化方案。再通过TEMS软件测试,分析网络参数设置,判断定位基站侧干扰产生的原因。最后通过分析中国移动GSM网络室分系统常见干扰问题,给出排查解决干扰的方法以及步骤,实现对GSM室内分布系统的网络优化。目前本文的室内分布系统干扰的研究和分析方法,已经在我公司推广使用,通过这种软硬件相结合的方式对室内分布系统的干扰进行分析,可以提高网络优化人员在日常工作中故障定位的效率,节约人力、物力成本,并可为公司的室内分布系统优化与维护工作提供一定的依据和指导。
[Abstract]:Survey data show that 70% of the mobile communication traffic comes from indoor systems. The indoor electromagnetic transmission environment is far more complex than outdoor. In order to protect the performance of indoor networks and improve the user experience. For indoor distribution system interference analysis and network optimization, to improve the service competitiveness of mobile operators, is of great significance. First, aiming at the coverage characteristics of different scenarios of indoor distribution system. The interference factors of indoor distribution system are studied. The influence of active equipment and passive device on the network is analyzed by testing the intermodulation index of dry amplifier and passive device. Find out the cause of interference and give the optimization scheme. Then through the TEMS software test, analyze the network parameters setting. Finally, by analyzing the common interference problems in the GSM network room subsystem of China Mobile, the methods and steps to solve the interference are given. To achieve the optimization of GSM indoor distribution system network. At present, the research and analysis method of indoor distribution system interference has been popularized and used in our company. Through the combination of software and hardware, the interference of indoor distribution system can be analyzed, which can improve the efficiency of fault location of network optimizer in daily work, and save manpower and material cost. It can provide some basis and guidance for the optimization and maintenance of indoor distribution system.
