ABSTRACT:
The invention relates to a method and arrangement for using location data in a cellular network. The cellular network includes a centralized map data bank (454) in which the map data are arranged in accordance with the quadtree hierarchy. The terminal includes a presentation means (23) for displaying map data according to the quadtree hierarchy. Some of the terminal's function keys (29) are arranged so as to function as selection keys for fetching more detailed map screens of the quadtree hierarchy to the display. The map data and possible auxiliary data fetched from the map data bank are saved in the terminal's memory for later use.
