MR覆盖率优化提升研究与应用

Research and Application of MR Coverage Optimization and Improvement

传统的DT和CQT网络测试无法评估网络覆盖情况,MR覆盖率能反映LTE网络覆盖情况。通过MR数据处理流程及两种话单栅格定位介绍MR覆盖率,阐述影响MR覆盖率的主要因素,从建维优一体化分析MR覆盖率优化提升流程,通过基于TA数据RF优化、功率优化和基于异频切换A2的RSRP触发门限调整应用于提升基站小区的MR覆盖率,从而提升网络覆盖,确保用户感知。

Traditional DT and CQT network tests can not evaluate network coverage,and MR coverage can reflect LTE network coverage.This paper introduces MR coverage through MR data processing flow and two kinds of calling bill grid positioning,illustrates the main factors affecting MR coverage,and analyzes the optimization and improvement process of MR coverage from the integration of construction,maintenance and optimization.Through RF optimization based on TA data,power optimization and RSRP trigger threshold adjustment of A2 based on the inter-frequency handover,the MR coverage of base station cell is improved and thus the network coverage to ensure user perception.
