TD-LTE网络覆盖问题精确化定位评估方法研究

摘要

It analyzes the coverage problems on TD-LTE network,focuses on network blind area,weak coverage,over coverage and overlay network. Around outdoor continuous coverage and indoor depth coverage,it introduces the methods of planning simu-lation,DT testing,CQT testing,customer investment,MR analysis,traffic statistics,summarizes TD-LTE network coverage problems accurate position approaches,focuses on the key technologies of grid level fine positioning,indoor and outdoor data distinguish,4G resident ratio analysis,to provide the technical support for the effective guidance of the late network planning, network optimization and engineering design.%针对当前TD-LTE网络存在的覆盖问题进行分析，详细介绍了网络盲区、网络弱覆盖、网络过覆盖、网络重叠覆盖等问题。从室外连续覆盖和室内深度覆盖2个方面着手，详细介绍了规划仿真、DT测试、CQT测试、用户投资、MR数据分析、话务数据统计等多种手段，归纳总结TD-LTE网络覆盖问题精确化定位评估方法，并重点介绍了栅格级精细定位、室内外数据区分、4G驻留比分析等关键技术，为有效指导后期网络规划、网络优化和工程设计提供了技术保障。
