Patent ID: 8249583

Claim:
Method for identifying and characterising a network incident on a service offered to a user of a telecommunications network, which comprises: collecting information relative to incidents of said network and of network element managers; identifying in said information an event relative to the complete unavailability of a network resource, either as a start status or end status of said complete unavailability of a network resource; notifying each identified event as a potential service incident PSI together with said start status or end status of the resource; comparing the status of the network resource of each potential service incident PSI with the status previously registered for said resource, which is determined by the previous potential service incidents with reference to that network resource in question, and updating this status if this status has changed; if this status has changed, accessing network resource configuration information and service configuration information stored in a network resource inventory and in a service inventory, respectively, and performing a splitting of each potential service incident PSI into as many specific potential service incidents SPSI as services in which said network resource is involved; determining, individually for each service, if each specific potential service incident SPSI gives rise to a service incident SI or an incident mutation IM, applying correlation techniques which take into account the network topology and, in the absence of the network topology, criteria of time-space proximity; identifying each of those incident mutations IM by means of a global fault identifier GFI identifying the service incident to which the incident belongs and a specific fault identifier SFI identifying the stage of evolution of the incident, said incident mutation including information about the type of incident, an identifier of the affected service, a list of affected network resources and the date and time in which the mutation has occurred; making those incident mutations modifying the list of resources affected by the incident progress, determining the set of users affected by said incident; and notifying the incident mutations to client processes based on subscriptions established by such clients.
