Abstract
A system and a method for determining a location area of a user using a mobile communication terminal in a geographical area covered by a mobile radio network, based on location probabilities for defined sub-areas of the geographical area. The location probabilities may be determined based on, e.g., field strengths expected in the sub-areas from antennas and based on the antenna used by the mobile communication terminal. The location probabilities may indicate, for a sub-area, the probability that the mobile communication terminal is located in the respective sub-area. At least one ellipse defining the location area may be determined, such as based on the location probabilities. The location probabilities may enable determining elliptical location areas of mobile users much smaller than the area each antenna does cover physically, but without the need for measuring at the mobile communication terminal signal properties such as signal strength or observed time differences.
