For interconnecting PSTN and IP Networks, We made a comparative analysis of signaling interworking and also studied SS7 Signaling process as a method for signaling interworking for using the establishment of PATN/IP network and seting up a phone call. As a methode of signalning interworking for linking an intelligent net-service between PSTN/IP Networks, we made researches of the merits and demerits about the access of INAP/SS7 using PSTN SCP and the call-routing of intelligent net-service using PSTM SSP in an IP network. We made a study of the protocol stack in IETF SIGTRAN as the realization for this
