Abstract

A device (D) is dedicated to processing traffic data for a system (OO) for optimizing a communications network including network elements (Ci) through which passes traffic defined locally by parameter values. The device (D) comprises processor means (MT) arranged: firstly to determine for selected elements of said network a traffic model from successive measured values of a parameter representative of said traffic; and secondly to compare the traffic models determined in this way to base traffic models each representative of one type of traffic so as to associate a base traffic model with one of said network elements when a measured traffic model that corresponds to it is comparable to said base traffic model.

Claims

1. A device (D) for processing traffic data for a system (OO) for optimizing a communications network including network elements (Ci) through which passes traffic defined locally by parameter values, characterized in that it comprises processor means (MT) arranged:

i) to determine for selected elements of said network a traffic model from successive measured values of a parameter representative of said traffic; and

ii) to compare the traffic models determined in this way to base traffic models each representative of one type of traffic so as to associate a base traffic model with one of said network elements when a measured traffic model that corresponds to it is comparable to said base traffic model.

2. A device according to claim 1, characterized in that said processor means (MT) are arranged to define sets of objects each grouping network elements associated with a common base traffic model.

3. A device according to claim 2, characterized in that said sets of objects are selected from groups of network elements and movement groups.

4. A device according to claim 1, characterized in that said processor means (MT) are arranged to effect said comparison by means of a proximity criterion.

5. A device according to claim 1, characterized in that said processor means (MT) are arranged to determine said traffic models from successive values of a parameter representative of said traffic as a function of selected dates and selected times on those dates.

6. A device according to claim 5, characterized in that said processor means (MT) are arranged to determine at least certain of said traffic models in a two-dimensional form.

7. A device according to claim 5, characterized in that said processor means (MT) are arranged to determine at least certain of said traffic models in a three-dimensional form.

8. A device according to claim 1, characterized in that it comprises analysis means (MA) arranged:

i) to collect traffic models associated with at least certain of said network elements and obtained periodically, with a first selected period, so as to have periodically, with a second period that is a multiple of the first period, a first set of traffic models for each of those network elements; and

ii) to analyze said traffic models of each first set to deduce a stability state for each first set obtained during each second period.

9. A device according to claim 8, characterized in that said analysis means (MA) are arranged to analyze said traffic models of each first set by comparing them with each other.

10. A device according to claim 8, characterized in that said analysis means (MA) are arranged to analyze said traffic models of each first set by comparing each of them to a base traffic model.

11. A device according to claim 8, characterized in that said analysis means (MA) are arranged to analyze said traffic models by effecting a comparison and effect said comparison by means of at least one proximity criterion.

12. A device according to claim 8, characterized in that said analysis means (MA) are arranged to determine stability state changes by comparing stability states associated with the same network element obtained during at least two successive second periods.

13. A device according to claim 8, characterized in that said analysis means (MA) are arranged to deduce at least certain of said stability states by excluding from their comparison a traffic model of the set that satisfies a selected criterion.

14. An optimization system (OO) for a communications network including network elements (Ci) through which passes traffic defined locally by parameter values, characterized in that it comprises a processor device (D) according to claim 1.
