Abstract: A wireless telecommunications system including a terminal device; first infrastructure equipment operable to communicate with the terminal device using a first radio access technology (RAT) and second infrastructure equipment operable to communicate with the terminal device using a second RAT. During a handover procedure for handover from the first infrastructure equipment as a source master infrastructure equipment to a third infrastructure equipment as a target master infrastructure equipment, the second infrastructure equipment is operable to communicate with the third infrastructure equipment using an interface associated with the second RAT so as to allow information necessary for completing the handover to be exchanged between the first infrastructure equipment and the third infrastructure equipment via the second infrastructure equipment.

Abstract: A terminal device and a method of operating a terminal device in a wireless communication network. The method comprises establishing, by the terminal device, a first radio connection with a first network access node for transmission of data via a first bearer and a second radio connection with the first network access node for transmission of data via a second bearer. Based on a difference between quality of service for the data transmission via the first bearer and the second bearer, a third radio connection is established between the terminal device and a second network access node for transmission of the data via the first bearer; and the third radio connection is established between the terminal device and the second network access node, a fourth radio connection is established between the terminal device and the second network access node for transmission of the data via the second bearer.

Abstract: A terminal device configured to receive a radio signal from which measurements can be used to assist in determining a position of the terminal device. The terminal device detects one or more system information blocks carrying position assistance information transmitted from the infrastructure equipment and estimates the position of the terminal device by combining the identified position assistance information with the radio signal received by the position detection receiver circuitry. Furthermore the terminal device receives from the infrastructure equipment an indication of relative risk that the position assistance information will change, and in response to the indication of the relative risk that the position assistance information will change to adapt the receiving of the one or more system information blocks to receive an updated version of the position assistance information in accordance with the relative risk.

Abstract: A method of operating a terminal device in a wireless telecommunications network comprising the terminal device and a plurality of base stations arranged into groups of one or more base stations supporting communications over different areas. The method including establishing a radio resource control (RRC) connection with an initially selected base station and entering an RRC connected mode of operation with respect to the initially selected base station and suspending the RRC connection with the initially selected base station and entering an RRC suspended mode of operation. The method includes subsequently transmitting a message to request a resumed RRC connection to a subsequently selected base station, wherein the subsequently selected base station is selected in accordance with a cell (re)selection procedure for the terminal device performed while in the RRC suspended mode of operation.

Abstract: Apparatus, systems, and methods provide for the cellular network to indicate preferences for controlling/regulating the background data traffic. Specifically, the network communicates a message to UEs that request that the UEs control background data transmissions. In response to the UEs receiving the message, the UEs reconfigure to control background date transmissions, such as controlling the volume of background data transmissions (e.g., reducing the volume of background data transmissions or the like). In specific embodiments the UE reconfigures by queuing background data and subsequently transmitting the queued background data at time intervals. As a result of such background data traffic control, the network experiences less radio traffic and problems related to cell overloading can be mitigated.

Abstract: A method of communicating data between a radio network infrastructure and a terminal device in a wireless telecommunications network. The method comprises establishing at a radio network infrastructure element there is data available for communication between the radio network infrastructure and the terminal device and transmitting a paging message for the terminal device from the radio network infrastructure element. The paging message comprises an indication of an identifier for the terminal device and an indication of a network allocated resource for use in subsequently communicating the data between the radio network infrastructure element and the terminal device. In response to receiving the paging message the terminal device transmits to the radio network infrastructure element a paging response indicating the terminal device received the paging message, after which the data is communicated between the radio network infrastructure element and the terminal device using the network allocated resource.
