摘要： A mobile communications system is described in which a mobile device is operable to communicate with base stations using a first radio technology and with other devices using a second radio technology. The mobile device maintains a control plane connection with a first base station and a user plane connection via a second base station. In case of an interference is detected due to concurrent use of the first and second radio technologies, the mobile device provides assistance information to the base stations, based on which the base stations alleviate the effects of the detected interference.

摘要： A gateway is described which facilitates a change of communication cell for a mobile device in a communication system, which includes a core network. The gateway receives messages from a base station operating a cell and forwards the messages received from the base station to the core network. The gateway intercepts a message relating to a change of communication cell, from a source cell in which the mobile communication device is located to a target cell, to determine if the core network needs to be notified of the change of cell. When it is determined that the core network needs to be notified, the gateway generates a message for providing information relating to the change of cell to the core network and transmits the message to the core network.

摘要： A communication system is described in which user plane communication and control plane communication for a particular mobile communication device can be split between a base station that operates a small cell and a macro base station. Appropriate security for the user plane and control plane communications is safeguarded by ensuring that each base station is able to obtain or derive the correct security parameters for protecting the user plane or control plane communication for which it is responsible.

摘要： A system is disclosed in which a mobile communication device establishes device-to-device (D2D) communication with another mobile communication device, and searches for a communication network whilst engaged in the D2D communication. When it finds a communication network, the mobile communication device indicates that it is engaged in the D2D communication. The mobile communication device continues, or does not continue, the D2D communication based on an authorisation by the communication network.

摘要： A communication system is disclosed in which a ProSe Relay UE allows a remote UE to connect to a base station and core network through the Relay UE. The base station broadcasts that it is capable of supporting ProSe Relay UEs. UEs that are in poor coverage areas can identify that the base station supports ProSe Relaying and can search for a relay UE with which to connect prior to trying to establish a direct connection with the base station. The Relay UE and the base station maintain context information for the relayed UE so that messages can be properly routed through the network and through the Relay UE.

摘要： A communications system is described in which a communication device is able to communicate with a base station via a first communication path and with an access node via a second communication path. The communication device provides to the base station an indication of whether or not the communication device is enabled to use the second communication path. The communication device receives, from the base station and in dependence on the indication, control data for changing between the first and the second communication paths, and changes between the first and second communication paths in accordance with the received control data.

摘要： A system is provided in which a user device communicates control data with a first base station and communicates user data with a second base station. The user device receives, from the first base station, configuration data specific to the first base station and configuration data specific to the second base station for configuring the user device to handle in-device coexistence interference. When the user device detects interference, it identifies the base station to which the interference relates, and controls the operating of its transceiver circuitry: i) using the first base station specific configuration data if it identifies that the interference is related to the first base station; and ii) using the second base station specific configuration data if it identifies that the interference is related to the second base station.
