METHOD AND SYSTEM FOR OPTIMISING THE PERFORMANCE OF A NETWORK

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 en-tity. The key performance indicators as well as the selected number of en-tities are used as elements in a first cost function, i.e. said first cost func-tion 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 perform-ance. Accordingly, since said first parameters directly relate to the key per-formance 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 sec-ond set of values of said first parameters are obtained. The key perform-ance indicators are determined again but this time on the basis of the sec-ond values of said first parameters and said first cost function is re-calculated 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 re-calculated 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 parame-ters are adopted as permanent parameters. L'invention concerne la détermination, dans un premier temps, des indicateurs de performances clés (KPI) pertinents pour une entité spécifique comprise dans le réseau et puis des premiers paramètres influençant les indicateurs de performances clés, aux fins d'optimisation des performances du réseau. Un certain nombre d'entités similaires à l'entité spécifique est sélectionné, des indicateurs de performances clés pertinents étant associés à chaque entité. Les indicateurs de performance clés, ainsi que le nombre sélectionné d'entités sont utilisés comme éléments dans une première fonction de coût, par exemple ladite fonction de coût est calculée en fonction des KPI et du nombre d'entités. Cette première fonction de coût est calculée aux fins d'évaluation des performances du réseau. Pa
