Abstract: This application discloses a device discovery method, a device, and a system, and relates to the field of communication technologies, to guarantee reliability of device discovery, reduce network overheads, and reduce network load. In this application, a discovery device (for example, a first device) discovers a device by multicasting/broadcasting a discovery request message. When receiving the discovery request message and determining that there is another device (for example, a third device) that meets a condition specified by the first device, a device (for example, a second device) may notify the first device.
