Abstract: PURPOSE: A method for tracing a transit call in an intelligent network IP(Intelligent Peripheral) system is provided so that all related software blocks can execute a trace function for an individual transit call using a call trace flag in case that tracing for an ISUP(ISDN User Protocol) transit call inputted to an IP system is required. CONSTITUTION: If an operator inputs an ISUP transit call trace command for a specific route using an OAM(Operation, Administration and Maintenance) terminal(S41), the command is transferred to a CTPM(Call Trace and Path setup Management block). The CTPM records the ISUP transit call trace command in a call trace command DB(S42). A UPC(ISDN User Part Control) confirms whether an ISUP transit call is inputted through the specific route(S43). In case that an ISUP transit call is inputted, the UPC transfers a trace message for the inputted ISUP transit call to the CTPM. The CTPM outputs the trace message to the operator through an OAMP(OAM Processor) in real time(S44). The UPC analyzes the inputted ISUP transit call and transfers an associated transit call event message to a software block related to the proceeding of the transit call after setting a call trace flag(S45). Also the UPC outputs a trace message for the presently processed transit call event message to the operator through the CTPM and the OAMP in real time(S46). The software block outputs the trace message for the transit call event message to the operator in real time. In case that interworking with other software blocks related to transit call proceeding is required, the software block sets the call trace flag to the transit call event message and transfers it to all the related software blocks(S47).
