An infrastructure equipment for transmitting data to or receiving data from one or more communications devices in a wireless communications network, the infrastructure equipment comprising: transmitter circuitry configured to transmit signals to the communications devices via a wireless access interface, receiver circuitry configured to receive signals from the communications devices via the wireless access interface, and controller circuitry configured to control the transmitter circuitry to determine that a network controlled function performed by any of the communications devices configured to transmit signals to or to receive signals from the infrastructure equipment is to be re-configured, and to determine that the communications devices are to receive updated configuration information for re-configuring the network controlled function, the configuration information being broadcast by the infrastructure equipment for the communications devices to receive, and to transmit a paging notification as a control message in the control channel indicating that the configuration information broadcast for the communications devices for the configuration of the network controlled function has changed, thereby providing the communications devices which are configured to perform the network controlled function with an indication to receive the updated broadcasted configuration information associated with the function, wherein the communications devices comprise a group of one or more communications devices which are configured in accordance with a specification which differs from a specification with which other communications devices which do not form part of the group are configured, wherein the paging notification transmitted in the control channel is a radio network temporary identifier, which uniquely identifies the network controlled function to be re-configured, the radio network temporary identifier being detectable by the group of one or more communications devices but not the other communications device which do not form part of the group, and the radio network temporary identifier being configured to indicate that the group of one or more communications devices have to re-read the system information block which comprises the updated broadcasted configuration information. transmitter circuitry configured to transmit signals to the communications devices via a wireless access interface, receiver circuitry configured to receive signals from the communications devices via the wireless access interface, and controller circuitry configured to control the transmitter circuitry to determine that a network controlled function performed by any of the communications devices configured to transmit signals to or to receive signals from the infrastructure equipment is to be re-configured, and to determine that the communications devices are to receive updated configuration information for re-configuring the network controlled function, the configuration information being broadcast by the infrastructure equipment for the communications devices to receive, and to transmit a paging notification as a control message in the control channel indicating that the configuration information broadcast for the communications devices for the configuration of the network controlled function has changed, thereby providing the communications devices which are configured to perform the network controlled function with an indication to receive the updated broadcasted configuration information associated with the function, wherein the communications devices comprise a group of one or more communications devices which are configured in accordance with a specification which differs from a specification with which other communications devices which do not form part of the group are configured, wherein the paging notification transmitted in the control channel is a radio network temporary identifier, which uniquely identifies the network controlled function to be re-configured, the radio network temporary identifier being detectable by the group of one or more communications devices but not the other communications device which do not form part of the group, and the radio network temporary identifier being configured to indicate that the group of one or more communications devices have to re-read the system information block which comprises the updated broadcasted configuration information.
