摘要
接入网关是软交换体系结构中必不可少的设备,用于将模拟用户接入到软交换系统中。接入网关除了实现媒体格式的转换外,还提供了各种业务功能。文章针对接入网关的各种协议,提出了设备的设计思路及实现方案,并根据接入网关在实际应用中的部署环境,创造性地提出了双网口冗余、自交换等方案,大大提高了设备的稳定性及可靠性。
The access gateway is an integrant device in architecture ofsoftswitch, used to access analog users to softswith system. The access gateway can not only realize the conversion between media formats, but also provide the various service functions. Aiming at various protocols of access gateway, this paper describes the design idea and implementation scheme. And according to the deployment environment of practice applications, it proposes double network cards redundancy, serf-switch, etc.,which can significantly enhance the stability and reliability of access gateway.
