摘　　要：本文主要阐述了利用爱立信TCP网络规划平台对CRH2型动车在不同时速、不同地理环境下切换、重选临界电平的推算过程及进行铁路覆盖时最合理的站距、方位角及天线类型选择等。This article mainly elaborated critical level inference process of handover and cell reselection when CRH2 trains run at the different speed, on the different geographical environment using the Ericsson TEMS CellPlanner, and reasoned the most reasonable distance, the azimuth and antenna type selection and so on.
