基于时间提前量与网络结构关联的高铁LTE覆盖优化探讨

结合高铁线上LTE网络的测试结果,同步利用网管指标对合宁高铁安徽段沿线的高铁基站采用基于时间提前量(TA)的网络覆盖距离估算.通过路测数据、基站覆盖半径与高铁沿线站址结构综合判断高铁沿线基站异常覆盖环境,快速提出RF及功率优化建议.使网络优化工作更具有针对性,提高LTE网络优化的工作效率.

LTE Coverage Optimization OF The high-speed rail Based on the Timing Advance and Network Structure

The site coverage distance of HeNing high-speed rail within the range of Anhui Province is obtained based on the Timing Advance technology ,which is combined with the LTE test result and network monitoring KPI counters. The RF and cell-power parameters optimization method can be obtained rapidly based on the DT test result, site coverage range and the site surroundings,which targets the network optimization work better and improves the LTE network optimization efficiency also.
