Abstract

The present invention provides apparatuses, methods, computer programs, computer program products and computer-readable media regarding building and applying operational experiences for CM operations. The present invention comprises collecting operational experience information on executed operations from various logical entities via an interface, the collected operational experience information including execution data, and performance data concerning the executed operation, analyzing the operational experience information of the executed operations, storing the operational experience information of the executed operations in the central entity, and arranging the operational experience information of executed operations into different groups in the central entity according to similarities in the analyzed execution data of the operational experience information.

Claims

1. A method for use in a logically central entity, comprising:

collecting operational experience information on executed operations from various logical entities via an interface,

the collected operational experience information including execution data and performance data concerning the executed operation, and

storing the collected operational experience information of the executed operations, and

arranging the operational experience information of executed operations into different groups in the central entity according to similarities in the analyzed execution data of the operational experience information.

2. The method according to claim 1, wherein

the operational experience information has been pre-processed by the various logical entities and exchanged between them via other relevant interfaces to enable the pre-processing.

3. The method according to claim 1, wherein

the performance data is obtained from a performance management database, the performance data being calculated by a verification function based on parameters obtained via an interface from the performance management database, and transferred back to the performance management database.

4. The method according to claim 1, further comprising:

calculating a diagnosis value of the executed operation based on the performance data of the executed operation and performance data of previous executed operations having similarities in at least some of the execution data, and

storing the calculated diagnosis value in association with the operational experience information.

31. A computer program product embodied on a non-transitory computer-readable medium, said computer program product including a program for a processing device, comprising software code portions for performing the method of claim 1 when the program is run on the processing device.

5. A method for use in a management entity, comprising:

retrieving operational experience information of at least one previously executed operation via an interface from a central entity, and

processing a planned operation under consideration of the retrieved operational experience information.

6. The method according to claim 5, further comprising:

analyzing execution data included in the operational experience information and determining whether the execution data of the previously executed operation have similarities with at least some of the execution data of the planned operation,

if it is determined that the execution data have similarities,

predicting an outcome of the planned operation based on the retrieved operational experience information.

7. The method according to claim 6, further comprising:

determining whether to execute the planned operation based on the predicted outcome of the planned operation.

8. The method according to claim 5, further comprising:

identifying execution data of an operation to be executed,

searching the central entity for stored operational experience information of previous operations based on the identified execution data,

analyzing the retrieved operational experience information of the previous operations,

if the previous operations having similarities in at least some of the execution data resulted in positive operational experiences,

retrieving parameters of the previous operations having similarities in at least some of the execution data from the operational experience information, and

applying the retrieved parameters for the operation to be executed.

9. The method according to claim 8, further comprising:

if the previous operations having similarities in at least some of the execution data resulted in negative operational experiences,

rejecting the execution of the planned operation.

processing a planned operation under consideration of the retrieved operational experience information.

21. The apparatus according to claim 20, wherein the at least one memory and the instructions are further configured to, with the at least one processor, cause the apparatus at least to perform:

analyzing execution data included in the operational experience information and determining whether the execution data of the previously executed operation have similarities with at least some of the execution data of the planned operation,

if it is determined that the execution data have similarities,

predicting an outcome of the planned operation based on the retrieved operational experience information.

22. The apparatus according to claim 21, wherein the at least one memory and the instructions are further configured to, with the at least one processor, cause the apparatus at least to perform:

determining whether to execute the planned operation based on the predicted outcome of the planned operation.

23. The apparatus according to claim 20, wherein the at least one memory and the instructions are further configured to, with the at least one processor, cause the apparatus at least to perform:

identifying execution data of an operation to be executed,

searching the central entity for stored operational experience information of previous operations based on the identified execution data,

analyzing the retrieved operational experience information of the previous operations,

if the previous operations having similarities in at least some of the execution data resulted in positive operational experiences,

retrieving parameters of the previous operations having similarities in at least some of the execution data from the operational experience information, and

applying the retrieved parameters for the operation to be executed.

24. The apparatus according to claim 23, wherein the at least one memory and the instructions are further configured to, with the at least one processor, cause the apparatus at least to perform:

if the previous operations having similarities in at least some of the execution data resulted in negative operational experiences,
