<p>A mobile communications device is configured to communicate data packets via a mobile communications network. The mobile communications network comprises a radio network part which includes a plurality of base stations providing a plurality of different radio access interfaces from which a plurality of different radio access bearer types can be formed for communicating the data packets from the mobile communications devices, and a core network part which includes a plurality of infrastructure equipment for communicating the data packets from the radio network part. The mobile communications device includes a radio bearer controller which is configured to determine a traffic profile of the data packets to be communicated via the mobile communications network from one of a predetermined set of possible traffic profiles, and to select one of the plurality of different radio access interfaces to provide a radio access bearer of a type most suitable for communicating the data packets from the mobile communications device in accordance with the determined traffic profile of the data packets. The bearer controller is thereby arranged to identify a most appropriate communications bearer for communicating the data packets to a mobile communications device based on an observed traffic profile of the data packets to be communicated, to make efficient use of available communications resources.</p> |
