M3ua Protocol To Achieve Interoperability Of Ss7 And Ip Network

In recent years, many new technologies come forth continuously,and especially broadband IP technology is their representative. These emerging new technologies have deeply changed the concept ,the system structure and running mode of the traditional telecommunications network. Even so, voice business still has the absolute advantage. Therefore, the integration of the data business and voice business is inevitable.To realize interworking of IP network and switched circuit network(SCN) .signaling gateway that has interworking function appears on the interface of IP network and SCN. SG transports signaling messages by SIGTRAN.M3UA protocol is adopted to complete interworking function of S100 signaling gateway in the paper. S100 signaling gateway can be used as a signaling agency and a signaling transfer point. S100 signaling gateway receives and sends standard ss7 messages on the SCN side . Standard SIGTRAN adaptation layer protocol M3UA and transport layer protocol SCTP are used on the packet-based network side. S100 signaling gateway has strong adaptation capacity, complete function and high reliability.
