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.

Dependent claims

A method of transmitting data from an infrastructure equipment of a wireless communications network to one or more communications devices or receiving data from the one or more communications devices at the infrastructure equipment, the method comprising:

transmitting a paging notification as a control message in a control channel indicating that the configuration information broadcast for the communications devices for the configuration of a network controlled function has changed, wherein the paging notification is a Specific SIB Change RNTI (SSC-RNTI),
whereby the communications devices which are configured to perform the network controlled function are provided with an indication to receive updated broadcasted configuration information associated with the function.

A method of transmitting data to or receiving data from one or more communications devices in a wireless communications network, the method comprising:

transmitting a paging message to one of the communications devices currently in an idle mode, the paging message indicating that the communications device establish a connection with an infrastructure equipment to receive downlink data transmitted from the infrastructure equipment,
receiving, as part of a procedure for establishing the connection for transmitting the downlink data, an indication from the communications device of a function being performed or about to be performed by the communications device,
determining, in accordance with a predetermined condition, whether the communications device should continue to establish the connection for receiving the downlink data from the communications device, and
in accordance with the predetermined condition, transmitting an indication to the communications device either to abandon the connection for transmitting the data to the communications device or to establish the connection and to transmit the downlink data.
