Abstract: The present invention relates to a method for establishing or resuming a wireless communication connection in a wireless communication network. According to the method, a first message is transmitted from a first device to a second device. The first message includes a request for the second device to provide a data link layer communication forwarding between the first device and a base station. Furthermore, a connection between the first device and the base station is established or resumed via the data link layer communication forwarding of the second device.

Abstract: A wireless communication device (10) controls changing of a connection of the wireless communication device (10) to an access node (100) of the wire-less communication network between: a relay based connection to the access node (100), and either a direct connection to the access node (100) or another relay based connection to the access node (100). The relay based connection extends via a device-to-device communication link (30) between the wireless communication device (10) and a first further wireless communication device (40). The other relay based connection extends via another device-to-device communication link (30′) between the wireless communication device (10) and a second further wireless communication device (40′). Further, the wireless communication (10) sends an indication to the access node (100). The indication enables the access node (100) to identify an existing Packet Data Convergence Protocolcontext, which was utilized before changing the connection, and to continue utilizing the existing PDCP context after the changing of the connection.

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 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 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.
