Abstract:
1. System for self optimizing a radio communication network comprising a plurality of radio cells, the system comprising: means for monitoring network resource consumption and quality parameters individually for each cell, and means for distributing network traffic dynamically between neighboring radio cells in order to maintain satisfactory quality of service in each radio cell, wherein the means for distributing network traffic is configured to retrieve input data, including performance measurement data and current network quality parameters, compute a custom quality index, QI, based on predetermined optimization goals for all radio cells in a selected area, sort the radio cells into groups according to their individual QI values, wherein a first group 1 contains a radio cell with the lowest quality index, and an endmost group nn contains radio cells with the highest quality index, improve the quality index for the radio cells of group 1 by adjusting the current cell parameters and shrinking the radio cell coverage area, reduce the quality index for the radio cells in group nn which are underutilized, by adjusting the current cell parameters and enlarging the radio cell coverage area, calculate the new network configuration parameters, and wherein the system is an extension system of an operation and maintenance center of a base station system, OMC-B, with interfaces to the OMC-B system and to assigned base station controllers, BSC, for completely automated measurement and data transfer of performance measurement data, and wherein the system comprises a database for compiling, processing and safekeeping performance measurement data received from OMC-B of the network radio cell sites, and wherein the system is part of a Network Management Center, NMC, in order to collect performance and quality measurements, statistics and alarm reporting from all OMC-B servers in the network and provide complete network statistics.
