A network entity, such as a mobility management entity (MME) 9, of a communications system 1 determines whether a radio bearer should be maintained or released for a communications device 2, 3. The communications device 2, 3 establishes the radio bearer via a base station 5 of the communications system 1 and communicates data, e.g. as a data packet in a payload of a radio resource control (RRC) message, using the established radio bearer. The communications device 2, 3 determines whether any further data is to be sent or received and/or whether a user-plane connection is required. The communications device 2, 3 then provides information to the network entity identifying a result of the determination for use, by the network entity, in determining whether the radio bearer should be maintained or released. The communications device may comprise a machine-type communication (MTC) device 2 operating in accordance with long term evolution (LTE) standards. |
