<p>A cellular mobile communications network includes a mobile station (40), a plurality of base transceiver stations (20), each for receiving uplink signals from the mobile station (40), and a base station controller (30) connected to the said base transceiver stations (20) for receiving therefrom such uplink signals. During a soft hand-off operation involving more than one of the said base transceiver stations (20) of the network, the mobile station (40) includes, in one or more such uplink signals transmitted thereby, respective signal measures for all of the base transceiver stations (20) involved in the operation, each signal measure serving to indicate the performance of a communications channel between the mobile station (40) and the base transceiver station (20) concerned. At least one of the base transceiver stations (20) includes soft hand-off control circuitry operable, when that station is involved in such a soft hand-off operation, to determine, based on an assessment of the signal measure(s) for one or more of the other base transceiver stations (20) involved in the soft hand-off operation, not to forward to the base station controller (30) such an uplink signal received from the mobile station (40).</p> |
