Patent attributes
A method and a base station for a mobile communications network. The base station includes a first transceiver configured to communicate over radio signals with a plurality of mobile terminals, in which the first transceiver configured to: transmit a first signal to serve a mobile terminal over multicast; receive from the mobile terminal information derived from the signal quality of a second signal received at the mobile terminal from a second transceiver; and receive from the mobile terminal further information on the quality of the first signal received at the mobile terminal from the first transceiver and on the quality of a third signal received at the mobile terminal from a third transceiver. The base station also includes a processor configured to, on the basis of a comparison of the quality of the second signal with a threshold, switch communications between the first transceiver and the mobile terminal from multicast to unicast; and on the basis of a comparison of the quality of the first signal and the quality of the third signal, instruct the mobile terminal to transition from being served by the first transceiver to being served by the third transceiver.
