Patent ID: 10536980

Abstract:
A method, device and system for interacting link information, which are used for solving the problem that at present there is no solution for a network side to learn the link information about a terminal supporting D2D communications and how to distinguish D2D link information from D2N link information. A link information reporting method in the embodiments of the present invention comprises: a terminal supporting D2D communications determining link information which is required to be reported to a network side, wherein the link information comprises D2D link information and/or D2N link information; and the terminal sending the determined link information to the network side on a D2N link, and indicating a link corresponding to the link information to the network side. Using the method in the embodiments of the present invention enables the network side to learn the link information about the terminal supporting the D2D communications and to distinguish whether the received link information is for the D2D link or the D2N link, so that the network side can more accurately manage and schedule the D2D link and the D2N link.
