摘　　要：随着电信网和互联网融合技术的发展 ,传统电路交换技术将逐步转向分组技术。下一代电信网是基于 IP的网络 ,SS7及呼叫控制原理是软交换控制系统的重要组成部分。首先介绍了 SS7与 IP互通的概念模型和 SIGTRAN协议体系 ,对 4种信令适配子层协议和 SCTP进行了详细的阐述和分析。给出了 3种主要的互通模式 ,对如何实现基于 IP的 SS7传送和构建 IP SS7网的相关技术进行了研究。With the development of converging telecommunication networks and Internet, legacy circuit-switched technology will be converted to packet-switched technology gradually. The next generation telecommunication networks will be based on IP. SS7 and the fundamental of call control are main components of softswitch control system. First of all, SS7-IP interworking conceptional model and SIGTRAN protocol architecture are introduced, following which four types of signaling adaptation sublayer protocols and SCTP are expounded and analyzed in detail. Finally, three leading interworking modes are presented with research and discussion on how pertinent technologies are used in delivering SS7 over IP and the construction of SS7 network based on IP.
