The communications terminal can communicate packets with the base stations via a wireless access interface provided by the base stations and send a signalling packet to the mobility managers, the signalling packet including user data intended for a destination, prior to establishing a signalling connection with the mobility managers. The mobility managers can, upon receiving a signalling packet from a communications terminal, detect the packet is not associated with any established signalling connection between the mobility managers and the communication device. The mobility managers can, responsive to the detection, transmit the user data in the signalling packet to the destination. Accordingly a short message may be sent in a reduced context or context-less manner. ## Claims ### Claim 1 A mobile communications terminal for communicating data in a mobile communications network, the mobile communications network comprising one or more base stations operable to provide a wireless access interface for the mobile communications terminal;
