Abstract

A telecommunication system comprising an O&M (Operation and Maintenance) hierarchical layer structure comprising at least two O&M nodes in at least two hierarchical layers, where O&M actions may be initiated at said nodes. The system is arranged for generation of an O&M transaction identifier when an O&M action is initiated, and is transferred to all nodes in all management layers used for said O&M action, which is initiated inside an O&M session, allowing O&M actions and sessions to be tracked in the O&M hierarchical layer structure. The present invention also relates to a method for tracking O&M actions in an O&M hierarchical layer structure.

Claims

1-18. -18. (canceled)

19. A telecommunication system, comprising:

an Operation and Maintenance (O&

M) hierarchical layer structure comprising at least two O&

M nodes in at least two hierarchical layers, where O&

M actions may be initiated at said nodes, wherein the system is arranged for generation of an O&

M transaction identifier, which O&

M transaction identifier is generated when an O&

M action is initiated, and is transferred to all nodes in all management layers used for said O&

M action, said O&

M action being initiated inside an O&

M session, allowing O&

M actions and sessions to be tracked in the O&

M hierarchical layer structure.

20. The telecommunication system according to claim 19, wherein the hierarchical layers comprise a network management layer, a sub network management layer and an element management layer, the layers forming an O&

M hierarchical layer structure.

21. The telecommunication system according to claim 20, wherein the network management layer at least comprises a node of the type Network Management System (NMS), the sub network management layer at least comprises a node of the type Sub-network Management System (SMS) and that the element management layer manages individual nodes which are interfaced by means of corresponding node element managers.

22. The telecommunication system according to claim 19 wherein, in any node where an O&

M action is initiated, said node is arranged to generate an O&

M transaction identifier and, when needed, to transfer the O&

M transaction identifier.

23. The telecommunication system according to claim 22, wherein said O&

M transaction identifier is generated when the initiating user is authenticated.

24. The telecommunication system according to claim 19, wherein each O&

M transaction identifier comprises an O&

M session identifier and an O&

M action identifier, the O&

M session identifier being generated when an O&

M session is initiated, and the O&

M action identifier being generated when an O&

M action is initiated inside an O&

M session, the O&

M transaction identifier thus being generated when an O&

M action is initiated.

25. The telecommunication system according to claim 19, wherein the O&

M transaction identifier consists of a node identification part comprising an IP-address, or a Fully Qualified Domain Name, and a running number.

26. The telecommunication system according to claim 19, wherein the O&

M transaction identifier comprises a node identification part further comprising an IP-address, or a Fully Qualified Domain Name;

an O&

M session identification part comprising a running sequence number; and

an O&

M action identification part comprising a O&

M session specific running number.

27. The telecommunication system according to claim 19, wherein the telecommunication system is a 3GPP based mobile telecommunication system.

28. The telecommunication system according to claim 27, wherein the telecommunication system is Wide Code Division Multiple Access (WCDMA).

29. The telecommunication system according to claim 19, wherein the telecommunication system is a wired system.

30. The telecommunication system according to claim 19, wherein all O&

M actions are initiated by O&

M users, which users are authenticated and authorized prior to being allowed to perform O&

M actions.

31. The telecommunication system according to claim 19, wherein Integration Reference Point (IRPs) are arranged for handling the communication between the nodes.

32. A method for tracking Operation and Maintenance (O&

M) actions in an O&

M hierarchical layer structure, comprising the steps of;

performing an O&

M action at a node in the O&

M hierarchical layer structure, said O&

M action being initiated inside an O&

M session;

generating an O&

M transaction identifier;

distributing the action in the form of a command to at least one other node in the O&

M hierarchical layer structure;

making the original O&

M transaction identifier available as a corresponding O&

M transaction identifier at said other node, the original O&

M transaction identifier thus being available in all nodes, making it possible to trace the O&

M activity throughout the O&

M hierarchical layer structure.

33. The method according to claim 32, wherein the O&

M transaction identifier is generated at any node where an O&

M action is initiated and, when needed, said node transfers said O&

M transaction identifier.

34. The method according to claim 32, wherein the O&

M transaction identifier is generated when the initiating user is authenticated.

35. The method to claim 32, wherein all O&

M actions are initiated by O&

M users, which users are authenticated and authorized prior to being allowed to perform O&

M actions.

36. The method according to claim 32, wherein the communication between the nodes uses Integration Reference Points (IRPs).
