    摘要: A bandwidth sharing method and device based on SDN control of terminal cell are disclosed. The bandwidth sharing method includes: determining, by a SDN controller, whether a trigger request for bandwidth sharing is received; upon receipt of the trigger request, selecting at least one second terminal cell for providing bandwidth sharing to the first terminal cell; controlling the first terminal cell and the at least one second terminal cell to jointly process the target service. The trigger request indicates a need of bandwidth sharing of a first terminal cell from other terminal cells when processing a target service on a backhaul link, and a bandwidth requirement of the target service equals to or exceeds a first predetermined threshold. The SDN controlled bandwidth-sharing scheme may ensure the application of a wireless backhaul sharing mechanism between T-SCs, thereby achieving flexible configuration of bandwidth resources on the backhaul link.

    摘要: The present invention discloses a connection management method in device-to-device (D2D) relay communication, a terminal and a base station. The connection management method in D2D relay communication includes: determining whether a relay terminal for performing the D2D relay communication is selected when an Radio Resource Control (RRC) connection between a remote terminal in a network coverage and a base station is not released; when the relay terminal is determined to be selected, determining whether the RRC connection with the base station can be released according to a resource configuration mode used by the remote terminal when performing a D2D communication. By utilizing the connection management method, problems of state transition and connection management of the terminal in the D2D relay communication can be solved.

    摘要: An embodiment of the disclosure provides a resource scheduling method for a vehicle communication, a device, a terminal and a base station, the method includes: receiving a plurality of groups of configuration parameters for semi-persistent scheduling allocated by a base station. A message feature after the current vehicle communication service is changed, and/or a message feature of a new vehicle communication service to the base station is sent, when the message feature of the current vehicle communication service is detected to be changed, and/or it is detected that the new vehicle communication message needs to be processed, indication information from the base station, and the indication information being used for indicating a semi-persistent scheduling process needs to be activated to the vehicle communication terminal is received; and the semi-persistent scheduling process needs to be activated is activated.
