本文首先对高速铁路的两大覆盖难点进行了介绍，并归纳总结了国内现有高速铁路主流的4种覆盖模式，尤其对高铁专网结构进行了简介。同时，辅以国内某高铁GSM和TD-SCDMA专网海量测试数据为基础，通过载干比、话音质量剖析了有效覆盖电平范围值。其次，对高铁专网分场景下的站间距、有效覆盖电平和成本三因素点进行了综合考评并提出相应站点设计建议。最后，结合高速铁路的两大覆盖难点对未来高铁覆盖模式进行了展望。

First of all, this paper introduces the two coverage problems of high-speed railway, and summarizes the four coverage mode of domestic existing high-speed railway mainstream. Especially, for proprietary high-speed railway network structure is briefly introduced in this paper. At the same time, the paper analysis the effective coverage level range value through the carrier-to-interference ratio, voice quality, based on a high-speed railway network GSM and TD-SCDMA mass data. Secondly, the high-speed railway network is divided into scenarios station spacing. Effective coverage level and the cost of three factors were comprehensive evaluation and put forward the corresponding site design suggestions. Finally, combined with the two cover dififculties of high-speed railway has carried on the forecast to the future high-speed railway cover pattern.
