An area definition is associated () with the clustered results by enclosing () the clustered results by a polygon, shrinking () the polygon by moving corners towards a contraction point and defining () the area definition as a shrunk polygon comprising a predetermined fraction of the clustered results. The contraction point is selected to be situated within the clustered results. The method also comprises creating () of position determination assisting data comprising a relation between the cell relation configurations and the associated area definitions. An arrangement for providing position determination assisting data is also presented.
