Abstract:
1. A method for determining an absolute position of a first mobile user device in a mobile-radio network, comprising: determining an absolute position of a second mobile user device with a first position-determining method wherein a first vector is determined indicating the absolute position of the second mobile user device relative to a first coordinate origin; determining a relative position of the first mobile user device relative to the second mobile user device with a second position-determining method, wherein a second vector is determined which indicates a position of the second mobile user device relative to the position of the first mobile user device as a second coordinate origin; and determining the absolute position of the first mobile user device on the basis of the absolute position of the second mobile user device and the relative position of the first mobile user device relative to the second mobile user device, wherein said determining the absolute position of the first mobile user device involves an addition of the first and the second vectors, wherein the first and the second position-determining methods are different methods.
