A method for processing radio measurement reports in a location tracking apparatus , the method comprising: acquiring a plurality of radio measurement reports related to transmission of reference signals between a mobile tag being location-tracked and at least one location tracking node having a fixed location within a location tracking area, wherein each radio measurement report comprises a transmission cycle index indicating a transmission cycle of a reference signal associated with the radio measurement report and a radio measurement metric computed from said reference signal associated with the radio measurement report; characterized in that the mobile tag and the at least one location tracking node operate according to Bluetooth technology, and the radio measurement report comprises an identifier of a transmitter and an identifier of a receiver of a reference signal associated with the radio measurement report, and the method further comprising: combining , after an expiry of a timer counting an acquisition period defining a maximum duration allowed for acquisition of the plurality of measurement reports, radio measurement reports having the same transmission cycle index, the same transmitter identifier, and the same receiver identifier; discarding any radio measurement report received after the expiry of the timer and having the same transmission cycle index as those being combined; and using the combined radio measurement reports in tracking the location of the mobile tag. acquiring a plurality of radio measurement reports related to transmission of reference signals between a mobile tag being location-tracked and at least one location tracking node having a fixed location within a location tracking area, wherein each radio measurement report comprises a transmission cycle index indicating a transmission cycle of a reference signal associated with the radio measurement report and a radio measurement metric computed from said reference signal associated with the radio measurement report; characterized in that the mobile tag and the at least one location tracking node operate according to Bluetooth technology, and the radio measurement report comprises an identifier of a transmitter and an identifier of a receiver of a reference signal associated with the radio measurement report, and the method further comprising: combining , after an expiry of a timer counting an acquisition period defining a maximum duration allowed for acquisition of the plurality of measurement reports, radio measurement reports having the same transmission cycle index, the same transmitter identifier, and the same receiver identifier; discarding any radio measurement report received after the expiry of the timer and having the same transmission cycle index as those being combined; and using the combined radio measurement reports in tracking the location of the mobile tag. combining , after an expiry of a timer counting an acquisition period defining a maximum duration allowed for acquisition of the plurality of measurement reports, radio measurement reports having the same transmission cycle index, the same transmitter identifier, and the same receiver identifier; discarding any radio measurement report received after the expiry of the timer and having the same transmission cycle index as those being combined; and using the combined radio measurement reports in tracking the location of the mobile tag. <EOS>
