Patent attributes
A method of operating a mobile communications network including a plurality of base stations and a base station for a mobile communications network, wherein the base station includes a plurality of transmitters, a plurality of receivers and a processor, is disclosed. Each transmitter is configured to transmit radio signals to a plurality of mobile terminals. Each receiver is configured to receive radio signals from a plurality of mobile terminals. The processor is configured to serve a mobile terminal via the transmitter over multicast/broadcast across a radio link; receive information from the mobile terminal being served by the transmitter, in which the information derives from signal quality of a multicast/broadcast serving signal received at the mobile terminal from the transmitter; and provide to the mobile terminal first instructions based on a first comparison of the quality of the multicast/broadcast serving signal received at the mobile terminal. The comparison is based on a first threshold; in which the first instructions instruct the mobile terminal to switch to unicast; and in which the processor is further configured to vary the first threshold in dependence on a measure of loading of the network.
