Connection management method and device in D2D relay communication, terminal and base station

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.
