ABSTRACT:
A method for identification of transceiver devices in a radio communication network, includes the steps of pre-identifying transceiver devices, judging that there is an ambiguous result obtained in the pre-identification, and verifying the ambiguous result by identifying the transceiver devices based on real time difference (RTD) values between the transceiver devices. Also the method may include checking measurement values of an observed time difference (OTD) obtained at a mobile transceiver device operated within a radio communication network constituted by transceiver devices, wherein the checking is based on real time difference values between the transceiver devices. Thus, an improved method is obtained for mobile station location determination and/or for taking handover decisions as well as a way of verifying the reliability of obtained measurement results.
