Abstract

An SS7 Network Preventative Maintenance System for detecting potential SS7 and switched network troubles, automatically analyzing the troubles, providing alarm and corrective action to avoid major network events. Real time monitors on SS7 links at the STP provide information on exceeded link load, exceeded Message Signaling Unit (MSU) frequency and network management status/error conditions in a Stage 1 Process. The Stage 1 Process provides alarm information to a Stage 2 Process which controls all Stage 1 associated monitors for an STP pair. Stage 2 reacts to Stage 1 signals to generate alarm and corrective action information which is passed on to a Stage 3 Process. The Stage 3 Process controls all Stage 2 Processes in the operating company. Stage 3 reacts to Stage 2 output to detect potential or real accompanying network trouble and generates alarm and corrective action information and displays in response thereto. Stage 3 also alerts a Stage 4 process which is connected to all Stage 3 Processes in a region. Stage 4 analyzes data from Stage 3 to determine if similar trouble could happen in another network where upon Stage 4 informs affected Stage 3 Processes regarding the same. Corrective action/trouble verification information is generated and passed on. An Interface to the network's surveillant system is provided.
