摘要
在近几年涌现的各种通信新技术中,以软交换技术为核心的下一代网络技术无疑是众多新技术创新的亮点之一。在软交换系统架构中,信令网关是实现PSTN和IP网络信令互通的核心关键设备。提出了一种应用于软交换系统中信令网关的容错7号信令协议栈的设计与实现方法,应用该协议栈构建的高可用的信令网关,适应了软交换系统下电信级信令网关的高可用性设计要求。
In recent years, the emergence of new technologies in various communications to softswitch technology as the core of the next generation network technology is no doubt one of the highlights in many new technological innovation. In softswiteh system architecture, the signaling gateway is the core of key equipment to achieve PSTN and IP network signaling interoperability. This paper provides a kind of design and implementation method of the fault-tolerant SS7 protocol stack that used in signaling gateway. Application of the protocol stack to build the high availability of the signaling gateway is adapted to the high availability design requirements of carrier-grade signaling gateway.
