Model-Based Alarm Correlation in Cellular Phone Networks

  title={Model-Based Alarm Correlation in Cellular Phone Networks},
  author={Peter Fr{\"o}hlich and Wolfgang Nejdl and Klaus Jobmann and Hermann Wietgrefe},
Though cellular phone networks already contain intelligent network elements diagnosing local faults, alarm bursts caused by network element failures cannot be handled properly by this technology. It is the responsibility of the operators to extract the relevant alarms from such a burst and identify the cause. To assist the operators, several alarm correlation tools have been developed. The current paper introduces a model–based solution to the problem of alarm correlation. We use an abstract… CONTINUE READING
