Abstract

A method for managing the configuration of a telecommunications network, the method comprises remotely creating a data file containing attributes of managed objects for one or more network elements of the network, uploading the data file to a management system of the network, inspecting the data file and identifying managed objects having attributes which have been created, varied or deleted, producing a database of the identified managed objects and the values thereof, and analysing the data in the database to manage the configuration of the telecommunications network accordingly. Also disclosed are an apparatus for performing the method, a management system incorporating the or apparatus and a telecommunications network incorporating the management system.

Claims

1. ) A method of managing configuration of a telecommunications network, the method comprising:

a) receiving in a management system of the network, a remotely created data file containing attributes of managed objects for one or more network elements of the network;

b) inspecting the data file and identifying managed objects having attributes which have been created, varied or deleted;

c) producing a database of the identified managed objects and the values thereof; and

d) analysing the data in the database to manage the configuration of the telecommunications network accordingly.

2. ) A method as claimed in claim 1, in which said inspecting step comprises inspecting the data file for commands contained therein which create, vary or delete managed objects.

3. ) A method as claimed in claim 1, in which said inspecting step comprises comparing the data file with a data file containing existing attributes of managed objects of network elements of the network and identifying managed objects having attributes which have been created, varied or deleted.

4. ) A method as claimed in claim 1, in which said data file is created by examining a data file downloaded from said management system, said downloaded file containing existing attributes of managed objects of network elements of the network.

5. ) A method as claimed in claim 1, comprising storing in said database the time and/or date when the respective identified managed objects are created, varied or deleted.

6. ) A method as claimed in claim 5, in which said analysing step comprises analysing any frequency in the creation, variation or deletion of each managed object and producing a policy for the synchronization of a managed object cache within said management system with the managed objects of network elements of the network.

7. ) A method as claimed in claim 6, comprising synchronising said managed object cache with the managed objects of network elements of the network in dependence of the frequency.

8. ) A method as claimed in claim 1, in which said analysing step comprises identifying repeating patterns in the creation, variation or deletion of managed objects, and using said analysis to suggest future workflows in the creation, variation or deletion of managed objects.

9. A method as claimed in claim 1, in which said analysing step comprises identifying a pattern in the creation, variation or deletion of managed objects which causes an error in the network, and using said analysis to provide a warning if the pattern is detected on a subsequent inspecting step.

10. ) An apparatus for managing configuration of a telecommunications network, the apparatus comprising:

a) a monitor for monitoring data files received by a management system of the network, the data files containing attributes of managed objects for one or more network elements of the network, the monitor being arranged to inspect the data file and to identify managed objects having attributes which have been created, varied or deleted;

b) a database for storing the identified managed objects and the values thereof; and

c) a processor for analysing the data in the database and to manage the configuration of the telecommunications network accordingly.

11. ) An apparatus as claimed in claim 10, arranged for connecting to a remote said management system.

12. ) An apparatus as claimed in claim 10, arranged within said management system.

13. ) An apparatus as claimed in claim 10, in which said monitor is arranged to inspect the data file for commands contained therein which create, vary or delete managed objects.

14. ) An apparatus as claimed in claim 10, in which said monitor is arranged to compare the data file with a data file containing existing attributes of managed objects of network elements of the network and to identify managed objects having attributes which have been created, varied or deleted.

15. ) An apparatus as claimed in claim 10, arranged to store in the database the time and/or date when the identified managed objects are created, varied or deleted together with the respective identified managed objects and the values thereof.

16. ) An apparatus as claimed in claim 15, arranged to analyse the frequency of creation, variation or deletion of each managed object and to produce a policy for the synchronization of a managed object cache within said management system with the managed objects of network elements of the network.

17. ) An apparatus as claimed in claim 10, arranged to identify repeating patterns in the creation, variation or deletion of managed objects, and to suggest future workflows in the creation, variation or deletion of managed objects.

18. ) An apparatus as claimed in claim 10, arranged to identify a pattern in the creation, variation or deletion of managed objects which causes an error in the network, and to use said analysis to provide a warning if the pattern is subsequently identified by said monitor.

19. ) A management system for a telecommunications network, the system comprising an apparatus for managing configuration of a telecommunications network, the apparatus comprising:

a) a monitor for monitoring data files received by a management system of the network, the data files containing attributes of managed objects for one or more network elements of the network, the monitor being arranged to inspect the data file and to identify managed objects having attributes which have been created, varied or deleted;

b) a database for storing the identified managed objects and the values thereof; and

c) a processor for analysing the data in the database and to manage the configuration of the telecommunications network accordingly.

20. ) A management system as claimed in claim 19, wherein the apparatus comprises the apparatus arranged for connecting to a remote said management system.

21. ) A management system as claimed in claim 19, arranged to synchronise said managed object cache with the managed objects of network elements of the network in dependence of the frequency.

22. ) A telecommunications network comprising a management system, the system comprising an apparatus for managing configuration of the telecommunications network, the apparatus comprising:

a) a monitor for monitoring data files received by a management system of the network, the data files containing attributes of managed objects for one or more network elements of the network, the monitor being arranged to inspect the data file and to identify managed objects having attributes which have been created, varied or deleted;

b) a database for storing the identified managed objects and the values thereof; and

c) a processor for analysing the data in the database and to manage the configuration of the telecommunications network accordingly.

23. ) A telecommunications network as claimed in claim 22, wherein the management system comprises the management system arranged for connecting to a remote said management system.
