Abstract: A method for use in a wireless telecommunications network, the method including: when a secondary base station exhausts a supply of unique parameter sets used in security ciphering of received split radio bearers, the secondary base station sends a notification to a master base station of a requirement to alter data handling resources allocated for handling split radio bearers received from the secondary base station in one or both of the master base station and a terminal device; and the master base station, in response to the notification, operating to effect an alteration in the said data handling resources.

Abstract: A method determining indication of an occupancy level in a mobile communications system including a base station to communicate with a mobile communications device via a wireless interface provided by a first frequency channel allocated to mobile networks communications for the mobile communications system and by a shared channel which can be shared by the mobile communications system and by other wireless communications systems. The method includes: a mobile communications device: measuring, for each of plural first time periods within a second time period, a channel utilization on the shared channel; determining channel occupancy states for the shared channel for each of the first time periods based on the measured channel utilization; and determining an indication of an occupancy level for the shared channel for the second time period, the indication of an occupancy level determined based on the occupancy states for the shared channel for each first time period.

Abstract: A method of transmitting/receiving data between a communications device and a mobile communications network including a wireless access interface providing communications resources within a system bandwidth and in time divided units allocated to communications devices of first and second types having different capabilities. The method generates, at the communications device, a random access message, by selecting a sequence from a predetermined set of sequences, which have been allocated to the communications devices of the second type and transmitting the random access message from the communications device to the wireless communications network, and in response to the random access message, receives a random access response at the communications device transmitted according to the capability of the communications device of second type, the random access message being recognized as from a communications device of second type from the selected one of the predetermined sequences allocated to the communications devices of second type.

Abstract: An infrastructure equipment that transmits a radio network identifier to a communications device for identifying the communications device when allocating communications resources of the wireless access interface for transmitting downlink data to the communications device. After the communications device has entered an inactive connected state, the infrastructure equipment transmits control signals including the radio network identifier for allocating communications resources of the wireless access interface for the communications device to receive downlink data, determine whether the communications device is still within a radio coverage area of the infrastructure equipment, and if the communications device has left the coverage area, transmit an indication to the one or more other infrastructure equipment via the inter-connecting interface to trigger a process for transmitting downlink data to the communications device from the one or more other infrastructure equipment.

Abstract: A communications device establishes a communications context for communicating data packets using a packet communications bearer from the communications device via mobile communications network in a connected state and releases communications context when in an idle state. A controller is configured in combination with a receiver to receive signalling information providing an indication of one or more functions performed by at least one of the receiver, a transmitter, or the controller which can be changed in a power saving state, and when in either the idle state or the connected state, to enter the power saving state in which the one or more of the operations performed by at least one of the receiver, the transmitter, or the controller are changed in accordance with the indication of the changed functions received in the signalling information from the mobile communications network.
