<p>A method for providing position determination assisting data comprises repetitions of establishing (210) of a cell relation configuration for a user equipment and performing (212) of a high-precision position determination for the user equipment. Results of the determinations belonging to the same cell relation configuration are clustered (214) in separate clustered results. An area definition is associated (220) with the clustered results by enclosing (221) the clustered results by a polygon, shrinking (222) the polygon by moving corners towards a contraction point and defining (223) 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 (230) 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.</p> |
