TRACING METHOD FOR CALL SETTING MESSAGE

摘要

PROBLEM TO BE SOLVED: To provide a tracing method for call setting message which improves the communication rate of a terminal device having tried calling by making it easy to grasp the call setting state of a system. SOLUTION: An operator accept the channel number of a terminal to be traced, a channel element or the kind of a message to be traced. Then a terminal device tries calling and then a base station control processor judges whether or not the terminal device is a specific terminal device to be traced and transmits the kind of the message to be traced to an assigned channel element when so. When the channel element to be traced is judged, the message kind is transmitted. The channel element having received the message kind sends a tracing report message to a BCP(base station control processor) at call setting time when the message to be traced is sent and received. The BCP having received the tracing report outputs tracing information to the operator's terminal.
