LTE越区覆盖问题自动定位方法研究与实践

Research and Practice of Automatic Detecting Solution of LTE Cross-Coverage

为了实现越区覆盖问题的高效自动定位,提出了基于覆盖数据的LTE越区覆盖问题自动定位方法。该方法通过空间数据函数计算,实现快速批量自动化判断小区是否存在越区覆盖问题。现场对相关天线参数进行优化调整后发现,大部分小区性能都得到明显提升,优化结果显示:通过该方法定位的问题小区准确度达95%以上,而且发现问题的耗时由数小时缩短到几分钟之内。

In order to achieve an efficient detection of LTE overshooting cells,a new solution is provided in this paper which is based on cell coverage data and multiple spatial database functions.Significant KPI improvement are confirmed in most of the cells after on-site tuning.The optimization results show that the detection accuracy using the proposed solution is over 95%,and the time required is reduced from couple hours to few minutes.
