Abstract

A method for improved determination of the position of a user device in a mobile-radio network is provided. In combination with adjacent, second user devices, the method is intended to achieve a relatively-accurate positioning even if only a relatively-inaccurate positioning method is available for the user device itself, especially if the latter is disposed inside a building. An absolute position of a second user device is determined with a first position-determining method. A relative position of the first user device relative to the second user device is then determined with a second position-determining method. Finally, the absolute position of the first user device is determined on the basis of the absolute position of the second user device and the relative position of the first user device relative to the second user device, wherein the first and the second position-determining methods are different methods.
