FIELD: wireless communication equipment.
SUBSTANCE: invention relates to wireless communication system. Infrastructure equipment forming part of a mobile communications network receives data packets from a communications terminal. Infrastructure equipment includes a scheduler configured to control a transmitter and a receiver to transmit and receive signals according to the wireless access interface, wherein the scheduler is configured to receive from the receiver an indication of a number of delay tolerant data packets and non-delay tolerant data packets in an input buffer of the communications terminal, the input buffer receiving data packets for buffering the data packets for transmission by the communications terminal via the wireless access interface. Scheduler is configured to determine in accordance with predetermined conditions which include the current state for radio communications and the amount of the delay tolerant data packets in the input buffer of the communications terminal and the amount of the non-delay tolerant packets in the input buffer either to allocate communications resources of the wireless access interface for the communications terminal for transmitting the non-delay tolerant data packets or transmitting the non-delay tolerant data packets and the delay tolerant data packets to the infrastructure equipment, or not to allocate the communications resources of the wireless access interface until the predetermined conditions are satisfied, and if the communications resources are allocated to the communications terminal to receive the delay tolerant data packets and the non-delay tolerant data packets or the non-delay tolerant data packets.
EFFECT: 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.
