摘要
从铁路专用LTE网络的基本构成出发,具体介绍服务质量测试指标和网络优化的主要措施。通过对无线场强覆盖、车地通道性能以及切换性能等关键参数的测试,可以客观评估列车高速移动状态下的网络性能指标,也为无线网络优化提供可信数据依据,使铁路专用LTE无线宽带通信系统的工程质量得到有效保障。
Based on the basic composition of LTE network for railways, the paper introduces the service quality test indexes and the main measures of network optimization. Trough the test of the key parameters such as wireless coverage, train-ground channel performance and switching performance, the network performance can be objectively evaluated under the state of train running with high speed, also can provide reliable data basis for the optimization of wireless network to ensure the engineering quality of railway LTE wireless broadband communication systems.
