Title:
DEVICE DISCOVERY METHOD, APPARATUS AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/246601
Kind Code:
A1
Abstract:
Provided in the embodiments of the present application are a device discovery method, apparatus and system, which method can solve the problems in the prior art of a device discovery delay being relatively long and the power consumption being relatively high. The device discovery method provided in the embodiments of the present application comprises: a first device sending a first request message to at least one second device, wherein the first request message comprises a feature value of a target device, and the feature value of the target device is used by a device, which has received the first request message, to perform matching between a feature value of the current device and the feature value of the target device; the second device receiving the first request message from the first device; and if the feature value of the target device successfully matches the feature value of the current device, sending a first response message to the first device, wherein the first response message comprises second device information of the target device. The device discovery method, apparatus and system provided in the embodiments of the present application can reduce a delay during a device discovery process, and can be applied in a process of device discovery, which can be applied to distributed networking.
