Dynamic fault analysis for a centrally managed network element in a telecommunications system

摘要

Model based fault analysing in a base station in a mobile telecommunication system, the base station having a fault manager and resources adapted to transmit fault indication signals to the fault manager. The fault analysing including functions for receiving into the fault manager a predetermined fault rule model of said resources in a fault rule configuration file; implementing a fault analysis algorithm of predetermined rules for analysing 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 resources a fault indication signal indicating 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; generating an alarm signal dependent on said result of the applied fault rule.
