Title:
PATH TIME DELAY INFORMATION ACQUISITION METHOD AND RELATED DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/233465
Kind Code:
A1
Abstract:
Provided by the present application are a path time delay information acquisition method and a related device, the method of an embodiment of the present application comprising: a first network element device generating time delay detection information, the time delay detection information comprising a timestamp, and the timestamp being used for representing the sending time of the time delay detection information; the first network element device sending the time delay detection information to a second network element device by means of a transmission path, wherein the transmission path is used for representing a multi-hop wireless backhaul link between the first network element device and the second network element device; the second network element device may determine time delay information of the time delay detection information according to the timestamp, and during subsequent path selection, a data transmission path may be selected by using the path time delay information, thereby reducing the signaling overhead and complexity of path selection.
