1. A method in a cellular radio communication network (NET 1 ) for ranking cell members of a set of neighbor cells (C 12 -C 18, C 31 -C 38, C 43, C 51, C 54 -C 58 ) registered in the cellular radio communication network (NET 1 ) as neighbor cells to a first cell (C 11 ) of the cellular radio communication network (NET 1 ), the method comprising the steps of: registering ( 301 ) for each cell member in said neighbor cell set, handover statistics reflecting how frequent said cell member is involved in handovers aiming at modifying active sets including at least said first cell to include said cell member; ranking ( 302 ) the cell members of said set of neighbor cells according to a predetermined rule based at least in part on the registered handover statistics for the different cell members in the set of neighbor cells.
