A method and an arrangement in a cellular radio communication network for preparing a measurement order list for transmission to a mobile station operating in a first cell. It is determined (502) whether at least one cell among the neighbouring cells is incapable of acting as a target for handoff of the mobile station. If at least one cell incapable of acting as a target for handoff is found, at least one control channel associated with such a cell is omitted when generating (503) said list by including control channels associated with neighbouring cells.
