1. A method for operating an infrastructure equipment forming part of a wireless communications network, the wireless communications network comprising a base station and a non-terrestrial network part, the non-terrestrial network part transmitting one or more spot beams to provide a wireless access interface for transmitting signals to and receiving signals representing data from a communications device within a coverage region formed by one of a cell or a spot beam forming the cell, the method comprising:
transmitting, to the communications device, an indication of a first condition to be met before the communications device should transmit assistance information to the infrastructure equipment, the first condition including at least a change in the coverage region of the cell based on movement of the cell,
receiving the assistance information from the communications device upon the first condition being met,
determining, based on the assistance information, whether a cell change of the communications device should be initiated, and
in a case that the cell change of the communications device should be initiated, initiating the cell change of the communications device.
