In contrast to the related art, in which the distance value is calculated exclusively from the timing advance value, the first mobile radio base station or the mobile communication terminal additionally calculates a second distance value, which is more accurate in comparison with the above distance value but is multi-valued, from the following parameters: a first carrier frequency signal and a second carrier frequency signal with a fixed frequency offset, an initial phase relation at the transmitting site of the first carrier frequency signal with respect to the second carrier frequency signal, and a measured phase relation (MP1) at the receiving site of the first carrier frequency signal with respect to the second carrier frequency signal. The distance between the mobile communication terminal and the first mobile radio base station is determined more precisely by comparing the two distance values. The method can be extended to a plurality of mobile radio base stations. In combination with location data of the mobile radio base stations, it is also possible to determine a location of the mobile communication terminal.
