摘要
基于公共交换电话网络大规模应用七号信令的实际情况,对软交换体系结构、信令网关、初始会话协议(SIP)进行了描述。并针对下一代网络的分层思想、软交换的互联互通结构和呼叫流程,提出了利用软交换交换核心平台和信令网关及SIP相互配合实现七号信令的解决方案。描述了软交换系统的七号信令软件结构、信令网关的软件结构,阐述了相应呼叫流程的实现。
For the SS7 signal used widely in public switched telephone network,this paper describes the architecture of softswitch and signalling gateway and SIP. Aiming at the hierarchical mechanism and framework of interworking and call flow of next-generation network,it brings forward the solution to realize SS7 by coordination of softswitch core platform, signalling gateway and SIP. The SS7 software structure of softswitch system and signalling gateway and the implementation of corresponding call flow are described.
