Monitoring Method For Call Handling Of Signaling Transfer Point In No.7 Signaling Network

摘要

PURPOSE: A call processing monitoring method at an STP(Signaling Transfer Point) in a No.7 signaling network is provided to execute call processing monitoring through STPs by inputting an OP(Originating Point) code and a DP(Destination Point) code to each STP, monitoring the signaling messages between two points through a signaling message processing part, collecting monitoring messages associated with call processing, and displaying them to an operator through an NMS(Network Management System). CONSTITUTION: An operator inputs codes for two signaling points to each STP's signaling message processing part DB(S51). Then, as the operator adds a flag to a relevant signaling message processing part DB, each signaling message processing part starts monitoring for call processing associated signaling messages transferred between the two signaling points(S52). In case that a signaling message from the OP is received to an STP, the STP's MTP(Message Transfer Part) confirms whether the received message is a signaling message for monitoring. The signaling message processing part of the MTP analyzes the routing label of the received signaling message(S53). In case that the received message is a signaling message for monitoring(S54), the signaling message processing part collects the call processing associated signaling message through monitoring(S55). Then the signaling message processing part transmits it to a local operation management part or a central NMS(S56). The operation management part or the NMS displays the call processing monitoring message, the received time of the message and the source STP of the message to the operator(S57).
