An operation and maintenance control point (OMCP) operates at an intermediate level in a telecommunications network between the network elements and the network management system (NMS). The OMCP reduces the processing load on the NMS, and rather than reporting symptoms, provides the NMS with suggested corrective actions to correct reported problems. The NMS executes the suggested corrective actions and compares the actual results in the network with predicted results. Feedback on the results is then provided to the OMCP to improve its analysis and provide more effective corrective actions are suggested if the problem recurs. By automatically interfacing with the NMS, which analyzes and executes the suggested corrective actions, the OMCP creates a self-engineering telecommunications network. |

DETAILED DESCRIPTION In one aspect, the present invention is an operation and maintenance control point (OMCP) in a telecommunications network having a plurality of network elements that report to the OMCP and a network management system (NMS) to which the OMCP reports.
The OMCP comprises a performance monitoring function that monitors performance of the network elements and determines quality of service (QoS) in the network, a trouble sniffer that receives performance and QoS data from the performance monitoring function and detects faults within the network, and an action proposal agent that receives performance and QoS data from the performance monitoring function and fault data from the trouble sniffer, and provides suggested corrective actions to the NMS.
In another aspect, the present invention is a self-engineering telecommunications network comprising a plurality of network elements (NEs), an operation and maintenance control point (OMCP) that receives preprocessed data from the NEs and determines suggested corrective actions, and a network management system (NMS) that receives the suggested corrective actions from the OMCP and executes them.
Each of the NEs includes means for collecting raw traffic data and exchange data, and means for preprocessing the raw data.
The OMCP includes a performance monitoring function that monitors performance of the NEs and determines quality of service (QoS) in the network, a trouble sniffer that receives performance and QoS data from the performance monitoring function and detects faults within the network, and an action proposal agent that receives performance and QoS data from the performance monitoring function and fault data from the trouble sniffer, and determines suggested corrective actions.
The NMS includes means for predicting results within the network of executing the suggested corrective actions, means for executing the suggested corrective actions, means for determining the actual results of executing the suggested corrective actions, and means for providing feedback to the action proposal agent regarding the actual results
