ABSTRACT:
The present invention relates to a scheduler selector and a method for improving network quality by controlling intercellular interference of a multi-cellular mobile radio communication network. The radio communication traffic is controlled by a user traffic scheduler principle. The network quality is improved by selecting another scheduling principle among a number of pre-defined and selectable scheduling principles than the scheduling principle working for the moment in a cell in said network. Said selection being initiated as a result of an intracellular Quality data processing wherein the network quality is determined to be possible to improve.
