我国铁路GPRS网络由本地网和核心网二级结构组成,GPRS本地网通过路由器接入铁路数据网或新建GPRS核心数据网,本地网设备之间的分组数据交换通过路由器搭建的IP网络平台实现。GPRS核心数据网的组网方式可采取与铁路数据网合一或单独建设方式。根据业务数据量采用铁路数据网的网络平台,为多种铁路数据业务提供服务,避免重复建设。
China’s railway GPRS network consists of local network and core network secondary structure, GPRS local network through the router access to the railway data network or the new GPRS core data network, packet data exchange between local network equipment through the router to build the IP network platform. GPRS core network data network can be taken together with the railway data network or a single way of building. According to the amount of business data network using the railway network platform for a variety of railway data services to provide services to avoid duplication.
