Communications Terminal And Method

Abstract: A communications terminal includes a transmitter configured to transmit signals a receiver configured to receive signals from the wireless communications network via a wireless access interface and a controller configured to control the transmitter and the receiver to transmit and receive the signals. The controller includes an input buffer for receiving data packets for transmission as the signals via the wireless access interface. The controller is configured to identify whether the received data packets are delay tolerant or non delay tolerant to determine a current state for radio communications for transmitting the data packets via the wireless access interface and in accordance with predetermined conditions which include a current state for radio communications and an amount of the delay tolerant data packets in the input buffer and an amount of the non delay tolerant packets in the input buffer either to transmit the non delay tolerant data packets or to transmit the non delay tolerant data packets and the delay tolerant data packets from the input buffer to the mobile communications network using the transmitter or maintain the delay tolerant or non delay tolerant data packets in the input buffer until the predetermined conditions are satisfied. An arrangement is thereby provided in which data packets which can be classified into at least delay tolerant and non delay tolerant data packets are transmitted by a communications terminal in a way which can conserve the power of the communications terminal and more efficiently utilise the communications resources of a wireless access interface provided by a mobile communications network.
