Embodiment 1

[0027] figure 1 It is a flowchart of a data transmission method according to an embodiment of the present invention. The method can be applied to a data receiving terminal to realize communication with a data sending terminal. The data receiving terminal and the data sending terminal can be two terminal devices in the same system , can also be two terminal devices in different systems. The specific implementation method is as follows:

[0028] Step S101: receiving the near field communication tag sent by the data sending terminal;

[0029] In this step, the data sending terminal selects the file to be sent and activates the application of the method of this embodiment, and then when it is close to the data receiving terminal within the NFC communication distance (within 10cm), the near field communication unit of the data sending terminal sends the near field communication tag Push (Push) to the data receiving unit, so that the data receiving unit receives the near field com...

Embodiment 2

[0038] figure 2 It is a flowchart of an NFC-based Bluetooth data transmission method according to an embodiment of the present invention. The method can be applied between communication devices in the same system, or between communication devices in different systems. The communication device uses Android Operating system, and has NFC unit and bluetooth device, and can be recognized and run normally by Android operating system. The specific implementation method is as follows:

[0039] Step S201: The communication sender selects the file to be sent through the communication device A, and selects the application using this method in the "Share" menu in the file manager. At this time, the NFC unit and the Bluetooth device of the sender can be turned on or off. If they are turned off, the application of this method will automatically turn on the NFC unit and the Bluetooth device.

[0040] Step S202: The communication sender brings the communication device A close to the commun...

Embodiment 3

[0048] image 3 It is a flow chart of the NFC-based WIFI data transmission method of the embodiment of the present invention, the method can be applied between communication devices in the same system, and can also be applied between communication devices in different systems, and the communication device adopts Android Operating system, and has NFC unit and WIFI device and can be recognized and run normally by Android operating system. The specific implementation method is as follows:

[0049] Step S301: The communication sender selects the file to be sent through the communication device S, and selects the application using this method in the "Share" menu in the file manager. At this time, if the sender's NFC unit and WIFI device can be turned on or off, if they are turned off, the application of this method will automatically turn on its NFC unit and WIFI device.

[0050] Step S302: The sender brings the communication device S close to the receiver's communication device ...

Abstract

The invention provides a data transmission method and a terminal device. The method comprises the following steps: a data receiving terminal receiving a near field communication label sent by a data sending terminal; the data receiving terminal parsing the near field communication label and obtaining transmission information; the data receiving terminal establishing connection with the data sending terminal according to the transmission information; and the data receiving terminal receiving data sent by the data sending terminal, wherein the transmission information is written into the near field communication label in a near field communication data exchange format. According to the invention, authentication is realized by use of a near field communication mode among devices so that the problem of identity fraud by use of a conventional authentication mode in a network space is effectively prevented, and data transmission security is guaranteed. Besides, conventional tedious hitting, selecting and pressing operation on the devices is replaced by short-distance approaching among the devices, so that a user can simply and rapidly realizing automatic connection with the devices to be connected for data transmission, and the requirement for minimized energy consumption can be reached.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a data transmission method and terminal equipment. Background technique [0002] With the increasingly powerful functions of mobile devices, such as multimedia functions, users have higher and higher requirements for transmitting large data on mobile devices. It is hoped that the data transmission process will have the characteristics of fast speed, simple operation, and high security. Currently, commonly used technologies for data and data transmission between mobile devices include Bluetooth technology, WIFI technology and Near Field Communication technology (NFC, Near Field Communication). [0003] Bluetooth technology has the characteristics of high communication rate and long communication distance. However, operations such as searching for devices, answering pairing, and connection confirmation need to be performed before data is formally transmitted. For use, such an...
