Abstract
It is provided a solution for controlling interference in a cellular telecommunication system. An interference controller of the cellular telecommunication utilizes interference level information received from another cellular telecommunication system in controlling interference towards a target cell suffering from high interference which degrades the grade of service in the target cell. The interference level information comprises information on levels of interference between neighboring cells of the other cellular telecommunication system. The interference controller analyzes the received interference level information and controls communication links in cells of the cellular telecommunication system determined to cause the highest interference towards the target cell. The cells determined to cause the highest interference towards the target cell are determined from the received interference level information.
