Problems solved by technology

[0002] Some smart devices with Wi-Fi (wireless fidelity, wireless fidelity technology) access functions, such as video boxes and game boxes, cannot independently complete the network connection with the router because they do not have input devices. Use a third party to obtain configuration information with the router, and establish a network connection with the router through the obtained configuration information
[0003] At present, the following two methods are mainly used to solve the problem that the smart device cannot independently complete the network connection with the router:
However, due to the one-way nature of information transmission in Sniffer mode and the characteristics of being easily affected by the Wi-Fi environment, UDP packets are often lost
In this way, smart devices often cannot capture all UDP packets carrying Wi-Fi configuration information, so that they cannot obtain complete Wi-Fi configuration information
Even if all UDP packets can be captured, the user equipment needs to send UDP packets containing Wi-Fi configuration information multiple times in a loop, which will take a lot of time and increase the workload of the user equipment and smart devices

Embodiment 1

[0036] refer to figure 1 , shows a flow chart of steps of a Wi-Fi network sharing method according to Embodiment 1 of the present invention.

[0037] This embodiment describes the Wi-Fi network sharing method of the present invention from the sending side of the broadcast probe request frame. The Wi-Fi network sharing method of this embodiment includes the following steps:

[0038] Step S102: Using the obtained encryption key to encrypt its own Wi-Fi configuration information and preamble information after combination.

[0039] Wherein, the Wi-Fi configuration information includes: the currently connected router information and the access password (PSK), and the preamble information (Preamble) is used to indicate that the broadcast probe request frame contains Wi-Fi configuration information.

[0040] The currently connected router information may be a router name, an SSID of the router, or a converted hash value of the router name, or of course a converted hash value of the ...

Embodiment 2

[0046] refer to figure 2 , shows a flow chart of steps of a Wi-Fi network sharing method according to Embodiment 2 of the present invention.

[0047] In this embodiment, the Wi-Fi network sharing method of the present invention is still described from the sending side of the broadcast probe request frame. The Wi-Fi network sharing method in this embodiment specifically includes the following steps:

[0048] Step S202: the sending device acquires an encryption key.

[0049] In this embodiment, the broadcast probe request frame and probe response frame of the Wi-Fi P2P scanning process are used to quickly transfer Wi-Fi configuration information between receiving devices. Among them, the sending device sends Wi-Fi configuration information to the receiving device through a broadcast probe request frame, and the receiving device returns a response message that the broadcast probe request frame has been received to the sending device through a probe response frame, so that the W...

Embodiment 3

[0082] refer to image 3 , shows a flow chart of steps of a Wi-Fi network sharing method according to Embodiment 3 of the present invention.

[0083] This embodiment describes the Wi-Fi network sharing method of the present invention from the receiving side of the broadcast probe request frame. The Wi-Fi network sharing method of this embodiment includes the following steps:

[0084] Step S302: Receive the broadcast probe request frame sent by the sending device.

[0085] In this embodiment, the receiving device is the device on the receiving side of the broadcast probe request frame. The receiving device starts P2P scanning, and waits to receive the broadcast probe request frame sent by the sending device.

[0086] Among them, the broadcast probe request frame carries encrypted Wi-Fi configuration information and preamble information. The Wi-Fi configuration information includes: the router information and access password that the sending device is currently connected to, a...

Abstract

The invention provides a Wi-Fi (Wireless-Fidelity) network sharing method and device. The method comprises a step of using an acquired encryption key to encrypt combined self Wi-Fi configuration information and preface information, wherein the Wi-Fi configuration information comprises current router information and an access cipher, and the preface information is used for indicating that a broadcast probe request frame comprises the Wi-Fi configuration information; and a step of sending the encrypted Wi-Fi configuration information and the encrypted preface information carried in the broadcast probe request frame to a reception device, in order to enable the reception device to establish a Wi-Fi network connection according to the Wi-Fi configuration information in the broadcast probe request frame. By means of the Wi-Fi network sharing scheme provided by the invention, the interaction time is saved, the work load of a transmission device and a reception device is reduced, and the safety of the Wi-Fi configuration information is enabled in the transmission process.

Description

technical field [0001] The invention relates to the technical field of network sharing, in particular to a P2P-based Wi-Fi network sharing method and device. Background technique [0002] Some smart devices with Wi-Fi (wireless fidelity, wireless fidelity technology) access functions, such as video boxes and game boxes, cannot independently complete the network connection with the router because they do not have an input device. Use a third party to obtain configuration information with the router, and establish a network connection with the router through the obtained configuration information. [0003] At present, the following two methods are mainly used to solve the problem that the smart device cannot independently complete the network connection with the router: [0004] The first method is: turn on the Wi-Fi hotspot mode of the smart device, and wait for the user device (that is, a third party) to connect; the user device scans the hotspot, and the user enters the pa...
