A communications terminal is provided for communicating data packets to and/or from a mobile communications network. The mobile communications network comprises a plurality of base stations for communicating data packets to or from the communications terminals via a radio access interface, and a core network part which is configured to communicate the data packets to and/or from the base stations of the radio network part. The core network part includes a mobility manager for monitoring a location of the communications terminal. The communications terminal is configured to attach to a first of the base stations of the mobile communications network, to transmit a short message data packet providing context information for communicating the short message data packet to the mobility manager via the first base station, to determine that communication of data packets would be better via a second base station, to attach to the second base station without informing the mobility manager, and to receive a down link data packet from the mobility manager via the second base station. Accordingly a reduced mobility management can be provided to a mobile communications device (such as a machine type communications (MTC) terminal) in which a mobility manager does not maintain a location of the mobile terminal and full handover is not supported allowing more simple forms of communications terminal to be implemented. |
