8. A method of receiving data at a communications device, the method comprising:
transmitting, by a transmitter, signals to one or more infrastructure equipment of the wireless communications network via a wireless access interface;
receiving, from a first of one or more infrastructure equipment, a radio network identifier allocated for identifying the communications device when allocating communications resources of wireless access interface for transmitting data to or receiving data from the infrastructure equipment, the one or more infrastructure equipment forming, with the wireless access interface, a radio access network for transmitting data to and receiving the data from the communications device;
entering an inactive connected state in which the receiver monitors signals representing downlink data transmitted from the first infrastructure equipment, the signals including the radio network identifier allocated by the first infrastructure equipment;
monitoring signals transmitted from one or more other infrastructure equipment for determining whether the communications device should select a second of the one or more infrastructure equipment for receiving downlink data from the second of the one or more infrastructure equipment; and
in response to the communications device leaving a radio coverage area for transmitting signals to and receiving signals from the infrastructure equipment, receiving downlink data from the one or more other infrastructure equipment,
wherein the communications device has left the radio coverage area when the infrastructure equipment has transmitted control signals to the communications device a predetermined number of times without receiving a response from the communications device.
