LTE网络通过经纬度测算距离核查冗余邻区

1、通过经纬度测算距离工具核查冗余邻区在LTE网络中，UE搜索PCI测量小区信息。如果搜索到重复的 PC,将造成切换失败。因此 需要定期对邻区进行核查，及时清理不合理的邻区关系。 通过测算站间距，可以排查距离过 远邻区，解决冗余邻区问题。本文档将介绍如何通过经纬度测算距离工具实现站间距测算。1如下所示为经纬度测算距离EXEL工具；分别输入源站点及邻接站点的经纬度，即可自动算出距离。Lon gitude 1Latitude 1Lon gitude2Latitude 2Dista nee (m)111.24268425.078384111.29155625.0075439299.65111.24268
