Abstract: A system is disclosed in which a network entity determines whether a radio bearer should be maintained or released for a communications device. The communications device establishes the radio bearer via a base station of the communications system and communicates data using the established radio bearer. The communications device determines whether any further data is to be sent or received and/or whether a user-plane connection is required. The communications device then provides information to the network entity identifying a result of said determination for use in determining whether the radio bearer should be maintained or released.

Abstract: A communication system (100) is disclosed which uses system frames of a first and a second type. In a system frame of the first type communication with a mobile telephone (3) is subject to a restriction and in a system frame of the second type communication with said mobile telephone (3) is not subject to said restriction. It is determined whether or not to communicate with said mobile telephone (3), in a current system frame, in dependence on whether the current system frame is a first type of system frame or a second type of system frame.

Abstract: A communication system is disclosed in which a control node generates configuration data for each of a plurality of MMEs operating in overlay networks. The configuration data defines a type of user equipment (UE) or a type of UE traffic to be serviced by each MME. The MME configuration data is provided to a base station and used to control selection of an MME to service a request from a UE. The control node monitors network traffic within and across the overlay networks and can reconfigure one or more MMEs to service different UE traffic types. This allows for improved flexibility in load balancing with overlay networks.

Abstract: A mobile radio communications network within which a mobile radio communications device is to operate with access to a Small Data Transmission (SDT) feature is disclosed. The network includes a first network device arranged to receive SDT signalling initiated by the mobile radio communications device and a second network device arranged to receive signalling from the first network device as part of an establishment procedure for attempted SDT communications, the first network device being further arranged to determine if SDT should be prevented for the mobile radio communications device and responsive to its signalling exchange with the second network device, and to initiate a SDT rejection message for use in the control of the mobile radio communications device if SDT is to be prevented.

Abstract: A system is disclosed in which a communications device communicates via a cell operated by a base station of a communications network. The communications device identifies that transmission of data to a communications node coupled to the communications network has been triggered; determines whether an indication of radio quality in the cell meets a required radio quality criteria responsive to the transmission being triggered. The transmitting element transmits the data to the communications network after a delay if the quality of radio signals does not meet the required radio quality criteria, and without the delay if the quality of radio signals meets the required radio quality criteria.
