Abstract
A communications system for communicating data to and from a communication terminal, including infrastructure equipment forming a mobile communications network arranged to transmit and receive signals representing data to and from the communication terminal via a wireless access interface. The communication terminal is configured to transmit and receive signals representing data to/from the infrastructure equipment and to enter a reduced-power state, during which the communication terminal is configured to periodically recover data from the signals received from the infrastructure equipment, to measure a parameter indicating a characteristic of at least some of the signals received from the infrastructure equipment during the reduced power state, and to exit the reduced power state and to transmit a message to the infrastructure equipment, the message requesting resources of the wireless access interface, in dependence upon the measured parameter relative to a predetermined threshold.
