The method further comprises performing () of a high-precision position determination for the user equipment. The establishing and performing steps () are repeated a plurality of times. Positioning points belonging to the same cell relation configuration are clustered () and a polygon is associated () with each result cluster. The association () comprises encompassing of a result cluster by a polygon, altering of the polygon corners along defined paths to improve a predetermined criterion, and counteracting that polygon corners are gathering at a minor portion of a circumference. The method finally comprises creating () of position determination assisting data comprising a relation between the cell relation configurations and the polygon.
