摘要:

针对高铁场景移动网络质量提升难度大、常规方法收效差的问题,探索了一种针对交通干线,特别是高铁场景移动通信用户感知提升的方法论体系。提出了“覆盖有主、重选合理、切换有序”的交通干线切换链优化核心思想;总结了“先覆盖控制,后参数优化,再特性加载”的三层实践结构模型;采用了拉线图方式关联空闲态、业务态测试数据以及基站工程参数,发现覆盖问题路段和小区,覆盖优化后匹配高速移动场景时延参数,加载业务质量和感知特性的方法,实现高铁网络质量和用户感知大幅提升。该方法从原理分析入手,经过实践应用,“标本兼治”解决网络问题,并可快速推广和复制。

关键词: 切换链, 覆盖有主, 重选合理, 切换有序, 拉线图, 标本兼治

Abstract:

In view of the difficulty in improving the quality of mobile network in high-speed railway scenes and the poor efficiency of conventional methods, a methodology system for improving the perception of mobile communication users was explored in traffic trunk lines, especially in high-speed railway scenes.The methodology system was based on handover chain optimization with the core idea of “primary covering, reasonable reselection and orderly switching”.It adopted a three-layer theoretical structure include covering control firstly, then parameter optimization, and feature loading last.It used idle state and service state data pull graph correlation to determine problem road sections and cells, match the delay parameters of high-speed mobile scenes, load service quality and perception characteristics, and greatly improved the high-speed railway network quality and user perception.This method started from the principle analysis, with practical application, it could effectively solve the network problems, which could be fully extended to other linear scenes.

Key words: handover chain, primary coverage, reasonable reselection, orderly switching, drawing diagram, solving root causes
