Method and system for identifying and characterizing the impact of network incidents on telecommunication services offered to users

System for identifying and characterizing an incident in a service offered to a user of a telecommunications network, comprising an unavailability selection module (1), a consolidation module (4), an aggregation module (10), a stabilization module (12) and a notification module (14), wherein:

• the unavailability selection module (1) is configured to:
• collect from said network and from network element managers (17) information relative to an incident of said network,
• identify 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, and
• notify each identified event to the consolidation module (4) as a potential incident in a service (3a)-(3n) together with said start status or end status of the resource;
• the consolidation module (4) is configured to:
• compare the status of the network resource of each potential service incident PSI (3a)-(3n) 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 update this status if it has changed;
• if it has changed, access network resource configuration information (5) and service configuration information (6) stored in a network resource inventory (7) and in a service inventory (8), respectively, and perform a splitting of each potential service incident into as many specific potential service incidents (9a)-(9m) as services in which said network resource is involved, and
• send said specific potential service incidents (9a)-(9m) to the aggregation module (10);
• the aggregation module (10) is configured to:
• determine, individually for each service, if each specific potential service incident (9a)-(9m) gives rise to a service incident SI or an incident mutation IM (11a)-(11p), applying correlation techniques which take into account the network topology and, in its absence, criteria of time-space proximity;
• identify each of said incident mutations (11a)-(11p) by means of a global fault identifier GFI identifying the service incident to which it belongs and a specific fault identifier SFI identifying the stage of evolution of the incident, and send it to the stabilization module (12), said incident mutation IM including information relative to the type of the incident, an identifier of the service which it affects, a list of affected network resources and the date and time in which the mutation has occurred;
• the stabilization module (12) is configured to make incident mutations (13) modifying the list of resources affected by the incident progress to the notification module (14), determining the set of users affected by said incident;
• and
• the notification module (14) is configured to notify the incident mutations (15a)-(15s) to client processes (16a)-(16s) based on the subscriptions established by such clients.
