| 摘 要： | GSM R网络中数据业务互联单元(IWF)具有信令控制与速率适配两大功能,可以实现移动网络与固定网络之间数据业务的互联。速率适配功能是IWF的核心,速率适配的过程基本可以分为速率变换和协议处理两个步骤,给出速率适配的模型描述。并以GSM R网络与铁路ISDN的互联实现车 地间的数据通道为例介绍IWF的具体应用。

| Abstract: | Data operation IWF in GSM-R network has the functions of signaling control and rate adaptation to realize data transmission between mobile network and fixed network. The function of rate adaptation is the core of IWF. The process of rate adaptation can be basically divided into two steps-rate conversion and protocol processing. The model of rate adaptation is described and the practical applications of IWF is demonstrated by the example of interworking the GSM-R network and CRC ISDN network to realize the data transmission channel between vehicle and land. |
