Abstract

A device is dedicated to optimizing configuration models of cells of a radio communication network. The optimization device comprises processor means adapted to analyze configuration data representing each model used to configure each cell of the network and any associated configuration parameter exception value(s) in order to determine analysis data representing a usage for each model in association with an exception value of at least one configuration parameter and to compare the analysis data to rules describing optimization of models as a function of usage in association with at least one exception value of at least one configuration parameter to determine optimizations of model(s).

Claims

1. A device for optimizing configuration models of cells of a radio communication network, each model consisting of at least one group of cell configuration parameters associated with respective selected values, which device comprises processor means adapted to analyze configuration data representing each model used to configure each cell of said network and any associated configuration parameter exception value(s) in order to determine analysis data representing a usage for each model in association with an exception value of at least one configuration parameter and to compare said analysis data to rules describing optimization of models as a function of usage in association with at least one exception value of at least one configuration parameter to determine optimizations of model(s).

2. A device according to claim 1, wherein said processor means are adapted to determine from said configuration data the number of cells configured with only a model and the number of cells configured with that model associated with an exception value in order to determine said usage of each model in association with at least one exception value.

3. A device according to claim 2, wherein said processor means are adapted, once they have determined a number of cells configured with a model and before determining the corresponding usage, to compare that number to a selected threshold in order to proceed to the determination of said usage if said number of cells configured using that model is greater than said selected threshold.

4. A device according to claim 1, wherein said processor means are adapted, in the event of reception of an authorization relating to a particular model optimization, to store said optimized model in first storage means in which data representing said models is stored.

5. A device according to claim 1, wherein said processor means are adapted to store the data defining at least some of the optimized models in first storage means in which data representing said models is stored.

6. A device according to claim 4, including said first storage means.

7. A device according to claim 4, wherein said processor means are adapted, in the event of storing data representing an optimized model in said first storage means, to update said configuration data so that it is consistent with said data representing the optimized model.

8. A device according to claim 1, wherein at least some of said rules are “

condition/action”

type rules.

9. A device according to claim 8, characterized in that at least some of said conditions apply to a usage threshold value.

10. A device according to claim 1, wherein said processor means are adapted to proceed to the determination of a new optimization of a model if the time elapsed since the last optimization of that model is greater than a selected threshold time.

11. A device according to claim 10, wherein said processor means are adapted to store data representing each model optimization in corresponding relationship to an optimization date and to determine said time that has elapsed since the last optimization of a model by comparing the current date to the stored date of the last optimization of said model.

12. A device according to claim 1, wherein said processor means are adapted to proceed to the determination of a new optimization of a model if the rate of replacement of said model by an optimized model is greater than a selected threshold rate.

13. A device according to claim 1, including second storage means in which said configuration data of the cells of the network is stored.

14. A radio communication network management system comprising an optimization device according to claim 1.

15. A radio communication network services management system comprising an optimization device according to claim 1.
