Embodiment 1

[0026] figure 1 It is a flow chart of the WIFI-based communication establishment method provided by Embodiment 1 of the present invention. This embodiment is applicable to the case of short-distance data transmission between terminals in a commercial WIFI scenario. This method can be implemented by the device of the WIFI-based communication establishment method. Execution, the device can be implemented by means of hardware and / or software, and the technology specifically includes:

[0027] S110. The sending end broadcasts and sends the beacon detection frame based on the WIFI protocol;

[0028] Wherein, the sending end and the receiving end are smart terminals that support the beacon sensing function, and the sending end is usually a terminal that supports WIFI set by the merchant. The sending end uses the WIFI protocol to broadcast a beacon detection frame, and judges whether there is a neighbor terminal device around through the beacon detection frame. The beacon detection ...

Embodiment 2

[0043] figure 2 It is a flow chart of the WIFI-based communication establishment method provided by Embodiment 2 of the present invention. This embodiment is based on the foregoing embodiments, and further provides a specific implementation method of the WIFI-based communication establishment method, that is, S150 at the sending end and the described The receiving end establishes a tunnel security mechanism, including:

[0044] S151. The TCP / IP three-way handshake is implemented between the sending end and the receiving end;

[0045] S152. Establish a Layer 2 wireless transmission tunnel between the sending end and the receiving end;

[0046] S153. The sending end and the receiving end use Layer 2 Wireless Tunneling Protocol (Layer 2 Wireless Tunneling Protocol, L2WTP) to encapsulate the data to be transmitted.

[0047] Among them, L2WTP is a tunnel encryption protocol. Any one or more encryption and decryption algorithms can be used in this protocol. For example, it can be...

Abstract

Embodiments of the invention disclose a method and a device for establishing communication based on WIFI. The method comprises the following steps: a sending end broadcasts a beacon detection frame based on a WIFI protocol; the sending end receives response to the beacon detection frame replied by a receiving end based on the WIFI protocol by unicast; the sending end unicasts a communication connection establishment request message to the receiving end responding to the detection frame; the sending end receives a communication connection establishment response message replied by the receiving end by unicast; a tunnel security mechanism is established between the sending end and the receiving end; and the sending end transmits data to the receiving end through the tunnel security mechanism based on the WIFI protocol. The method and the device for establishing communication based on WIFI provided by the embodiments of the invention are used for achieving close distance data transmission between terminals, and the application of the WIFI protocol improves user information interaction and resource sharing efficiency and security in different commercial WIFI scenes.

Description

technical field [0001] Embodiments of the present invention relate to wireless communication technology, and in particular to a method and device for establishing communication based on WIFI. Background technique [0002] Wireless Fidelity (Wireless Fidelity, WIFI) technology is a technology that connects terminals such as personal computers and handheld devices (such as mobile phones) to each other in a wireless manner. At present, the WIFI mainly utilizes two frequency bands of 2.4 GHz and 5 GHz in the Industrial Scientific Medical (ISM) frequency band. Since the WIFI frequency band does not require any telecommunication operating license in the world, it provides a wireless air interface that can be used worldwide with extremely low cost and high data bandwidth for wireless devices. Users can quickly browse the web within the WIFI coverage area, and answer and make calls anytime, anywhere. WIFI technology, like Bluetooth technology, belongs to the short-range wireless t...
