Abstract

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.

Claims

1. A method of model based fault analysing in a base station in a mobile telecommunication system,

the base station having:

data processing means adapted to control the activities of the base station;

a fault manager function realised by means of software code executable by the data processing means;

a plurality of software and/or hardware resources adapted to realise functions of the base station and to transmit fault indication signals to the fault manager code;

the method comprising the steps of;

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 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;

generating an alarm signal dependent on said result of the applied fault rule.

2. The method of claim 1, wherein:

the fault rule configuration file is loaded for generating said analysis tree when initiating the fault manager function code.

3. The method of claim 1, wherein:

the fault rule configuration file is loaded for generating said analysis tree in response to a load control signal.

4. The method of claim 1, further comprising the steps of:

checking an update parameter devised for indicating an updated fault configuration file;

in response to said update parameter indicating the presence of an updated fault configuration file, loading an updated fault rule configuration file and generating an updated analysis tree data structure.

5. A base station in a mobile telecommunication system, the base station having:

data processing means adapted to control the activities of the base station;

a fault manager function realised by means of software code executable by the data processing means;

a plurality of software and/or hardware resources adapted to realise functions of the base station and to transmit fault indication signals to the fault manager code;

comprising;

means for receiving into the fault manager a predetermined fault rule model of said resources in a fault rule configuration file;

means for implementing a fault analysis algorithm of predetermined rules for analysing received fault indication signals dependent on said predetermined fault rule model;
