Automatic Integrated Control Loop For Fault, Performance And Service Quality Management

Abstract

A method includes receiving fault management data and service quality management data from an integrated feedback control loop, wherein a first set of faults in the fault management data is correlated with service quality management data if a root cause of the first set of faults is known and wherein a second set of faults in the fault management data are categorized as silent faults if no root cause of the second faults is known, The silent faults in the fault management are correlated with the service quality management data. The disclosure includes prioritizing analysis of the silent faults that affect the service quality management data, and prioritizing repair of faults in the fault management data that affect the service quality management data.
