Abstract

A technique for determining a correlation among events occurring in one or more network elements is provided. The correlation among the events results from a propagation of a root event through communication entities of the one or more network elements. In a method implementation the technique comprises the step of receiving a plurality of event messages from one or more network elements, wherein an event message pertaining to an event reported by a particular network element signals an occurrence context, the occurrence context comprising one or more context identifiers describing an internal communication state of the communication entity in which the event occurred at the time when the event occurred. In another step, a set of correlated events linked by identical context identifiers is determined. Based on the set of correlated events, the root event may be identified.

Description

technical field [0001] The present invention generally relates to determining correlations between events occurring in one or more network elements of a communication system. Correlation of events results from propagation of root events through communicating entities of said one or more network elements. Background technique [0002] In modern communication systems, network elements are equipped with a fault management function, which involves generating an alarm when a certain fault is detected. When a fault occurs in a communication entity of a network element (eg, in a protocol layer), the service provided by the communication entity may be degraded or completely blocked. Consequently, network elements and / or other communicating entities of other network elements that depend on these services will also exhibit failure symptoms and may start generating alarms themselves. Therefore, a single fault may propagate through a large portion of the communication system and cause...
