Technique for creating a knowledge base for alarm management in a communications network

摘要

A technique for creating a knowledge base for alarm management in a communications network is disclosed. In a method aspect, the method comprises the steps of defining a set of alarm properties observable for at least one managed element of the communications network; grouping incoming alarms into at least one alarm group based on heuristics; correlating the set of alarm properties with the at least one alarm group to thus generate at least one correlated alarm record; and constructing the knowledge base on the basis of the at least one correlated alarm record.
