Patent ID: 8498635

Claim:
A method of analyzing faults based on models, the method performed at a base station in a mobile telecommunication system, the base station having data processing means adapted to control activities of the base station; the data processing means having a fault manager and a plurality of functional resources adapted to transmit fault indication signals to the fault manager, the method comprising the steps of: receiving at the fault manager a predetermined fault rule model of said functional resources in a fault rule configuration file; implementing a fault analysis algorithm of predetermined rules for analyzing received fault indication signals dependent on said predetermined fault rule model; generating an analysis tree data structure dependent on the fault rule configuration file; receiving from one of said functional resources a fault indication signal comprising identification and classification information; retrieving an applicable fault rule in the analysis tree data structure dependent on said fault indication signal; evaluating the result of the retrieved fault rule applied on said fault indication signal; and generating an alarm signal dependent on said result of the applied fault rule.
