Abstract
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 base transceiver stations (20) for receiving therefrom such uplink signals. During a hand-off operation involving more than one of the base transceiver stations (20) of the network, a subset of those base transceiver stations (20) involved in the hand-off operation is selected, the subset being those base transceiver stations (20) which are to forward a received uplink signal to the base station controller (30). At least one of the base transceiver stations (20) involved in the hand-off operation is operable, when that station is involved in such a hand-off operation, to determine, based on the subset of base transceiver stations, whether or not to forward to the base station controller (30) such an uplink signal received from the mobile station (40). Such a cellular mobile communications network can be effective in reducing the load on the fixed network (5) when the mobile station (40) is fast-moving.
