Abstract
The invention relates to a network node and a method for handling alarms in a communications network. The method comprises, for a set S of alarms collected in the communications network during a time period T: —obtaining a first and a second type of alarms and their time of arrival from the set; and applying Kernal Density Estimation on the respective first and second type of alarms, by applying a distribution function to each occurrence of the first and second type of alarms; thus obtaining a respective distribution function for the first and second type of alarms over the time period T. The method further comprises determining a maximum correlation between the distribution function for the first type of alarms and the distribution function for the second type of alarms, and determining the time shift between the distribution functions associated with the maximum correlation; and obtaining an indication of a mutual relation between the first and second type of alarms based on the maximum correlation and the time shift. The method further comprises comparing the obtained indication with at least a first threshold, and managing the alarm types based on the comparison.
