Position determination assisting data is provided for performing position determinations based on this assisting data. The position determination assisting data comprises area definitions, each of which being related at least to a respective cell relation configuration. The cell relation configuration is determined at least by cell-IDs of cells fulfilling a specific radio condition criterion when received. Preferably, the cell relation configuration is also dependent on relative radio conditions between different cells and/or transmission mode. The area definitions are in particular example embodiments polygons, which preferably are re-calculated successively, automatically and on-line. The recalculations are based on high-precision position measurements of opportunity, clustered at least with respect to prevailing cell relation configuration for that user equipment performing the high-precision position measurements. Preferably, the area definitions are calculated with a predefined confidence level. |
