Abstract

A method, a system, and a device for implementing device addition in a Wireless Fidelity (Wi-Fi) Device to Device (D2D) network are provided, which belong to the field of communication. The method includes: receiving, by a first D2D client device, a first add request message forwarded by a D2D master device, in which the first add request message carries an identifier of a new device to be added to the D2D network; receiving a first Personal Identification Number (PIN) code of the new device; and forwarding the received first PIN code to the D2D master device, in which the first PIN code of the new device is used for implementing that the D2D master device performs Wi-Fi Protected Setup (WPS) security configuration of the new device according to the first PIN code. Therefore, in the Wi-Fi D2D network, when a new device is to be added, a PIN code of the new device inputted by a user is received by the D2D client device, and the PIN code is forwarded to the D2D master device, so that the addition of the new device through the recommendation of the D2D client device is implemented, and the work continuity of the user using the D2D master device is ensured.
