DEVICE-TO-DEVICE COMMUNICATION METHOD, APPARATUS AND SYSTEM

Document Type and Number:

WIPO Patent Application WO/2017/024890

Kind Code:

A1

Abstract:

Disclosed in an embodiment of the present invention is a device-to-device (D2D) communication method. The method comprises: a base station in a first network determines that it is required to configure a D2D communication time slot in the first network, wherein the D2D communication time slot is used for a D2D communication between a first terminal in the first network and a second terminal in a second network, and the first network and the second network are different home networks; the base station sends a resource request to a third terminal in the first network, wherein the resource request is used to request the third terminal to report to the base station information used for configuring the D2D communication time slot; and the base station receives a response to the resource request sent by the third terminal, wherein the response to the resource request contains the information used for configuring the D2D communication time slot obtained by the third terminal from the second network. The method can significantly reduce the signaling overhead in the D2D communication.
