Abstract: An infrastructure equipment (eNodeB) is configured to transmit a paging notification which indicates that configuration information which is broadcast in a cell to all communications devices which are configured to operate in accordance with a network controlled function has changed. Communications devices which are configured to perform the network controlled function are provided with an indication that they should receive the configuration information which is broadcast in order to reconfigure the network controlled function. A communications device which is not configured to perform the network controlled function may not recognise the paging notification or at least may detect that it does not need to receive the updated configuration information for the network controlled service. Such communications devices may therefore remain in an idle mode thereby saving power.
