Method and system for optimising the performance of a network
First Claim
1. A method for optimising the performance of a network, in particular a radio network performance, comprising the steps of:
- determining relevant key performance indicators for an entity within the network and first parameters, upon which said key performance indicators depend on, selecting a number of similar entities, calculating a first cost function on the basis of the determined key performance indicators and the selected number of entities, in order to evaluate the network performance on the basis of first values of said first parameters, wherein said first values of said first parameters represent the current values of said first parameters, adjusting the values of said first parameters resulting in second values of said first parameters, re-calculating said first cost function on the basis of the key performance indicators as determined according to said second values of said first parameters to evaluate the network performance, comparing the result of said first cost function according to said first values of said first parameters with the result of said first cost function according to said second values of said first parameters to determine whether the network performance has improved, adopt said second values of said first parameters as permanent parameters if the network performance on the basis of said second values of said first parameters has improved.

Abstract
When optimising the performance of the network, first of all, the relevant key performance indicators for a specific entity within the network as well as first parameters, which influence the key performance indicators, are determined. A number of entities similar to said specific entity is selected, wherein relevant key performance indicators are associated to every entity. The key performance indicators as well as the selected number of entities are used as elements in a first cost function, i.e. said first cost function is calculated on the basis of the KPI and the number of entities. Said first cost function is calculated in order to evaluate the network performance. Accordingly, since said first parameters directly relate to the key performance indicators, the network performance will depend on the values of said first parameters.
Thereafter the values of said first parameters are adjusted, so that a second set of values of said first parameters are obtained. The key performance indicators are determined again but this time on the basis of the second values of said first parameters and said first cost function is recalculated on the basis of these key performance indicators. The result of said first cost function calculated on the basis of said first values of said first parameters is compared to the result of said first cost function recalculated on the basis of said second values of said first parameters. This comparison is carried out to determine whether the network performance has improved. When the network performance has improved due to the adjusting of said first parameters, said second values of said first parameters are adopted as permanent parameters.
