Abstract

In a fault management system, a method and a converting unit for converting correlated sequences of network alarms into a high level language format are disclosed. The method comprises receiving episodic alarm sequence for the correlated sequences obtaining a high level language scheme, and converting the episodic alarm sequence using the accessed high level language scheme into a high level language format, to enable more efficient and reliable fault management using the converted episodic alarm sequence in high level language format.

Claims

1. A method, within a fault management system, of converting correlated sequences of network alarms into a high level language format, comprising the steps:

receiving episodic alarm sequence for the correlated sequences,

obtaining a high level language scheme,

converting the episodic alarm sequence using the accessed high level language scheme into a high level language format,

to enable more efficient and reliable fault management using the converted episodic alarm sequence in high level language format.

2. The method of converting correlated sequences of network alarms according to claim 1, wherein the step of converting the episodic alarm sequences comprises sorting the episodic alarm sequences in relation to the accessed high level language scheme.

3. The method of converting correlated sequences of network alarms according to claim 1, wherein the step of converting the episodic alarm sequence comprises mapping high level language elements onto the episodic alarm sequence.

4. The method of converting correlated sequences of network alarms according to claim 1, wherein the step of converting further comprises assembling mapped high level language elements.

5. The method of converting correlated sequences of network alarms according to claim 1, wherein the step of obtaining a high level language scheme, comprises accessing an XML or SDL scheme.

6. The method of converting correlated sequences of network alarms according to claim 1, wherein the high level language elements comprise graphically displayable building blocks associated with the function of the high level language element.

7. A fault management unit to be provided in a fault management system, for converting correlated sequences of network alarms into a high level language, said fault management unit comprising:

an episodic alarm sequence receiving unit, arranged to receive episodic alarm sequences for the correlated sequences,

a high level language scheme providing unit, arranged to provide a high level language scheme,

a converting unit being arranged to convert the episodic alarm sequence using the accessed high level language scheme into a high level language format,

a control unit being arranged to control converting of the episodic alarm sequence using the accessed high level language scheme into a high level language format, to achieve a high level language formatted episodic alarm sequence.

8. The fault management unit according to claim 7, wherein the high level language providing unit is arranged to provide an SDL language.

9. The fault management unit according to claim 7, wherein the converting unit further comprises a mapping unit arranged to map high language elements onto the episodic alarm sequences.

10. The fault management unit according to claim 9, wherein the converting unit further comprises an assembling unit arranged to assemble mapped high level language elements forming high level language formatted episodic alarm sequences.

11. The fault management system comprising a fault management unit according to claim 7, for management of network alarms.

12. A computer program product for converting correlated sequences of network alarms into a high level language, comprising computer program code to make a fault management unit perform when said code is loaded into said fault management unit,

receiving of episodic alarm sequence for the correlated sequences,

obtaining of a high level language scheme,

converting the episodic alarm sequence using the accessed high level language scheme into a high level language format,

to enable more efficient and reliable fault management using the converted episodic alarm sequence in high level language format.
