一种基于干扰分析的LTE网络站址评估方法

摘要

For the utilization of the old sites in LTE network, a method of the evaluation of the present sites and the adjustment of the en-gineering parameters based on the interference degree is put forward. In the actual network, the problematic sites can be found based on the simulation and analysis of the interference degree of each site. Then the engineering parameters of those sites may be adjusted, or those sites may be abandoned according to the actual condition.%利旧3G站址部署LTE网络是目前LTE网络建设的有效途径，针对如何准确找到不适宜利旧的站址，提出了利用干扰度对现网站址进行评估和工参调整的方法，通过定义基站干扰度来衡量每个基站对周围基站的干扰情况，根据仿真结果对有问题的站进行逐个分析、调整或舍弃。经验证，将该方法应用到实际网络筛选中，能有效定位站址或工参有问题的基站。此外，该方法还可以应用到新规划站址合理性的评估和工参的调整。
