Cellular mobile networks will be more and more complemented by high speed wireless hotspots. In order to use this additional access technology efficiently, terminals must be able to discover the wireless hotspots located around them. Classical methods based on measurements on the physical network interface are not sufficient because they neither can detect neighbouring hotspots nor are they well-suited for multi-mode interfaces, which can use only one access technology at once. Therefore, we suggest to use a model-based access discovery method, which applies queries to a location-based data model. In this paper, we describe how to collect field strength measurement from mobile terminals, how to convert them to polygons describing the coverage of wireless hotspots, and how to retrieve the coverage information.
