A method for assisting in cell combination management in a cellular communication system is presented. The method comprises obtaining of network statistics, comprising statistics associated with pairs of cells as well as cell loads. At least one candidate cell combinations selected. The candidate cell combination is a combination of cells for which a mobility measure deduced from the mobility statistics for pairs of cells participating in the combination of cells exceeds a first predetermined threshold. A total load capacity is determined for each of the candidate cell combinations. A cell combination procedure is recommended for a first cell combination. A cell combination, for which a load margin exceeds zero, is allowed to be chosen as the first cell combination. The load margin is a difference between the determined total load capacity and a sum of the cell loads. A network node performing such method is disclosed.
