网关是业务系统与业务网关交互的桥梁,不同业务系统用同一协议与网关节点通讯,网关节点再通过不同的协议适配器与不同的业务网关交互。这里的网关平台立足于3G环境,为移动通信系统提供通用网关,对网关节点功能模型进行了详细设计,其具备基础服务、能力支撑、策略控制、数据持久等功能,实现了与通用网关内部和通用网关与不同业务系统之间的通讯,屏蔽了业务系统与支撑平台的多协议接口。
The gateway is the bridge between the business system and the service gateway. Different service systems communicate with the gateway nodes using the same protocol. The gateway nodes interact with different service gateways through different protocol adapters. The gateway platform here is based on the 3G environment and provides a general gateway for the mobile communication system. The functional model of the gateway node is designed in detail. The gateway platform has the functions of basic service, capability support, policy control and data persistence, The communication between common gateway and different business systems shielded the multi-protocol interface of business system and supporting platform.
