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.

29. A method of determining a correlation among events occurring in one or more network elements, wherein the correlation among the events results from a propagation of a root event through communication entities of the one or more network elements, the method comprising:
-
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 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, wherein at least one of the event messages indicates two or more of the context identifiers pertaining to different communication entities involved in the event; and determining a set of correlated events linked by identical context identifiers, wherein each context identifier comprises a first parameter indicative of a context type and a second parameter indicative of an associated identification value, and wherein two events are determined to be correlated when the associated event messages; (i) comprise at least one of the context identifiers of the same context type; and (ii) have the same identification values. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48)

49. A method of generating an event message enabling determination of a correlation among events occurring in one or more network elements, wherein the correlation among the events results from a propagation of a root event through communication entities of the one or more network elements, the method being carried out in a network element and comprising:
-
detecting occurrence of an event in a first communication entity of the net-work element; determining one or more context identifiers describing an internal communication state of the first communication entity at the time when the event occurred; generating an event message configured to signal two or more of the context identifiers pertaining to different communication entities involved in the event; and reporting the event message towards a central network management entity, wherein each context identifier comprises a first parameter indicative of a context type and a second parameter indicative of an associated identification value, and wherein two events are determined to be correlated when the associated event messages; (i) comprise at least one of the context identifiers of the same con-text type; and (ii) have the same identification values. - View Dependent Claims (50, 51)
