Method and system for optimising the performance of a network

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 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.

Description

technical field [0001] The present invention relates to a method and system for optimizing network performance. Background technique [0002] The Telecommunications Managed Network (TMN) model provides a widely accepted approach to how a service provider's business is managed. The TMN model includes 4 layers that are usually managed in a triangular or pyramidal manner, in which the top layer is business management, the second layer is service management, the third layer is network management, and the bottom layer is unit management. The management decisions at each level are different from each other, but related to each other. As work progresses from top to bottom, each layer pushes out requirements for the layer below. As the work proceeds from the bottom up, each layer sends important data resources to the upper layer. The TeleManagement Forum's (TMF) TMN defines guidelines for optimizing functionality and processes. Third Generation Cooperation Project ((3 rd Gener...
