| 摘 要： | 首先介绍了铁路整体运营服务质量(QoS)指标,提出利用自顶向下方式拆解,定义相应的GSM-R网络电路域QoS指标的具体内容,阐述了QoS指标对CTCS-3级车-地数据传输的影响。然后着重描述了QoS指标与CTCS-3级车-地数据传输的相互作用关系,并分析了在QoS指标已知合格的条件下,如何设置CTCS-3级数据传输的参数以更好地适应GSM-R网络的特性。

| Abstract: | This article introduces the whole QoS index of railway at first,suggests a top-down method to analyzing the content of GSM-R network CSD QoS index,then points out the effects of these QoS indexes to the CTCS-3 Train-To-ground data transmission. Finally it describes how the QoS indexes and CTCS-3 Train-To-ground data transmission are related to each other. It analyzes how to configure the C3 data transmission parameters to adapting to the GSM-R network features better at the condition of qualified QoS indexes. |
