Overview of Fault Management

FM enhances network reliability.


The fault management function is one of five functions (performance management, configuration management, security management, fault management, and charging management) that make up a telecommunications management network. The primary purposes of this function are to monitor the operating anomalies and problems of devices and networks in real time and to monitor, report, and store data on faults and device running conditions. Fault management also provides alarms, helping users isolate or rectify faults so that affected services can be restored.


With the popularity of networks, complexity of application environments, and expansion of network scales, our goal must be to make network management more intelligent and effective. Improving and optimizing fault management will help us meet this goal. Improved fault management can achieve the following:

  • Reduction in the volume of alarms generated

    Alarm masking, alarm correlation analysis and suppression, and alarm continuity analysis functions are supported to provide users with the most direct and valid fault alarm information and to lighten the load on the fault management system. Such support for efficient fault location and diagnosis enhances the ability of the network element (NE) management system to manage same-network NEs and cross-network NEs.

  • Guaranteed alarm reporting

    Use of the active alarm table and internal reliability guarantee mechanism allows alarms to be displayed immediately so that faults can be rapidly and correctly located and analyzed.
