The traffic loading in a CDMA or WCDMA system changes all the time and there can be large variations during the day or week. This means that the system sometimes operates near or at overload level. Thus, in the worst cases, there are periods of abnormal loadings from cell to cell, which is beyond any traffic forecast. On other occasions, some cells are slightly loaded. Therefore, the invention relates to a method and device for optimisation radio resource utilisation in a radio access network, wherein a trade-off between cell capacity and link quality is dynamically adjusted according to the actual cell load. In the case of high cell load connection quality of links within the cell is decreased and in case of low cell load connection quality of links within the cell is improved.
