Embodiment 1

[0042] see figure 1 It is a structural diagram of an application scenario of the embodiment of the present invention. The area A is the area covered by the wifi network, and the area includes at least one terminal device. The terminal device can be an intelligent terminal such as an iPhone, android, or other Mobile Internet Devices (Mobile Internet Devices, MIDs), mobile smart terminals, etc. are not specifically limited in the embodiment of the present invention. It is assumed that the area A includes tablet computers, PCs, notebooks, PAD terminal equipment, etc., and each terminal equipment is connected by a user The datagram protocol (User Datagram Protocol, udp) communication method is used to complete the direct connection between the terminal device and the terminal device, and then the data transmission is realized by establishing a socket link. The following is the data transmission process between any two terminal devices in area A. illustrate:

[0043] see figure ...

Embodiment 2

[0053] The application scenario of this embodiment of the present invention is the same as that of Embodiment 1, please refer to image 3 , image 3 A flow chart showing the implementation of the wifi network data transmission method provided by Embodiment 2 of the present invention is described in detail as follows:

[0054] In S301, the first terminal device establishes a communication connection with the second terminal device through the UDP protocol.

[0055] In S302, according to the communication connection, the first terminal device sends the data information of the data to be transmitted to the second terminal device through the UDP protocol, and receives the data information returned by the second terminal device according to the data information transmitting a data feedback message, where the transmission data feedback message includes information on whether the second terminal device receives the data to be transmitted;

[0056] In this embodiment, the data infor...

Embodiment 3

[0063] The scenario of this embodiment of the present invention is the same as that of Embodiment 1, please refer to Figure 4 , Figure 4 A flow chart showing the implementation of the wifi network data transmission method provided by Embodiment 3 of the present invention is described in detail as follows:

[0064] In S401, the first terminal device broadcasts the basic information of the first terminal device through the UDP protocol, so that the second terminal device obtains the basic information of the first terminal device, and the basic information carries the IP address information of the first terminal device;

[0065] In this embodiment, the basic information includes at least the IP address information of the first terminal device, and may also include device information of the first terminal device and the like.

[0066] In this embodiment, the first terminal device broadcasts the basic information of the first terminal device through the broadcast protocol mode ...

Abstract

The present disclosure relates to the field of Internet technology. A data transmission method, apparatus and terminal device of a Wi-Fi network are provided according to the disclosure. The method including: a first terminal device establishes a communication connection with a second terminal device via the UDP protocol; according to the communication connection, the first terminal device establishes a socket connection with the second terminal device; and the first terminal device sends the transmission data to the second terminal device via the socket connection. The disclosure makes it possible that, once terminal devices are within the same Wi-Fi network, the data transmission may be directly performed between the terminal devices, without dependency on the server. Also, as the data transmission process does not need the operations such as identification, adding friends, and so on, the data transmission process is much easier and faster.

Description

technical field [0001] The invention belongs to the technical field of the Internet, and in particular relates to a data transmission method, device and terminal equipment of a wifi network. Background technique [0002] With the development of Internet technology and mobile terminal technology, people often need to transmit various videos, audios and documents between terminal devices. At present, the data transmission between terminal devices is mainly through the transfer of the server. Specifically: the terminal device participating in the data transmission needs to register with the server, log in to the personal account through the server, and obtain personal information and friend information. If the other party has not been added as a friend, you need to Add the other party as a friend, and the data transmission process is that the sending terminal device first transmits the data to the server, and then the server transmits the data to the receiving terminal device. ...
