| Abstract: | 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. |
