<p>The present invention relates to a positioning node and method for determining a position of a target UE in a cellular mobile telecommunication network. The network comprises means for identifying the RBS that the target UE is connected to, whereby the location of the identified RBS is known, and means for selecting a first and a second additional UE, wherein at least one of the first and second additional UEs is connected to a RBS that is different from the RBS that the target UE is connected to. The positioning node comprises input means adapted to receive information associated with measurement of the round -trip -time between the target UE and the identified RBS, information associated with measurement of the round -trip -time between the first additional UE and the RBS it is connected to, information associated with measurement of the round -trip -time between the second additional UE and the RBS it is connected to, information associated with measurements between the target UE and a first additional UE, information associated with measurements between the target UE and a second additional UE, information associated with measurements between the first additional UE and the second additional UE, and a calculator adapted to determine the position of the target UE by using the knowledge of the identified RBS and the received information.</p> |
