Document Type and Number:
Japanese Patent JP6619448
Kind Code:
B2
Abstract:
The present invention relates to the communications field, and discloses a path selection method, a device, and a system, to resolve a problem in the prior art that if a distance between two terminal devices performing direct communication is relatively long or channel quality changes relatively greatly, the two terminal devices cannot perform D2D communication. A specific solution is: A first device receives first discovery information sent by a second device, adds an ID of the first device to the first discovery information, and sends the first discovery information to which the ID of the first device is added, so that a destination device can determine a transmission path after receiving the first discovery information. The present invention is used for path selection.
