Embodiment Construction

[0064] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0065] figure 2 It is a flowchart of a method for discovering a D2D device according to an embodiment of the present invention. Such as figure 2 As shown, the method may include the following processing steps:

[0066] Step S202: the first D2D device obtains the configuration information of the D2D device discovery message;

[0067] Step S204: The first D2D device exchanges information with the second D2D device according to the configuration information of the D2D device discovery message until the first D2D device is discovered by the second D2D device or the first D2D device gives up being discovered by the second D2D device.

[0068] In the related art, the method of performing D2D device d...

Abstract

The invention discloses a method and device for discovering device-to-device (D2D) devices. According to the method, the first D2D device obtains configuration information of D2D device discovering messages; information interaction is performed between the first D2D device and the second D2D device according to the configuration information of the D2D device discovering messages until the first D2D device is discovered by the second D2D device or until the first D2D device gives up being discovered by the second D2D device. According to the technical scheme, the effects that wireless resources are saved, disturbance and collision probability is reduced, and the spectral efficiency is improved are achieved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a device-to-device D2D device discovery method and device. Background technique [0002] Device-to-Device (D2D for short) communication based on cellular network is a new type of technology that directly communicates between multiple user equipment supporting D2D functions under the control of the system, which can effectively Reduce system resource occupation, increase spectral efficiency of cellular communication system, reduce terminal transmission power consumption, and save network operating costs to a large extent. The working mode of D2D based on cellular network is as follows: figure 1 shown. [0003] The D2D device needs to complete the discovery of other nearby D2D devices before performing D2D transmission. D2D device discovery means that a D2D device can be discovered by one or more other D2D devices and its identity can be identified. At present, the D2D device...
