    • The invention discloses a method (300) for use in a cellular network (100) with a plurality of cells (110, 120, 130) in which there can be Mobile Stations, MS (132), with one base station, BS (111, 121, 131 ), per cell. In the network, an MS can be handed over from a first BS (131 ) of a first cell (130) to a second BS (121 ) of a second cell (120) if certain criteria are fulfilled. The method (300) comprises measuring (310) the traffic load in at least said first and second cells, and calculating (320) the difference between the load in the first cell and the load in the second cell. The method also comprises lowering (340) the criteria for handover from the first BS to the second BS if the load difference between the first cell and the second cell exceeds (330) a first threshold value (T1 ).
