Problems solved by technology

[0003] However, since near-field communication requires short distances and transmits data through near-field sensing, only a small amount of data can be transmitted in terms of data transmission. Of course, there are currently some improvement solutions, specifically: NFC+Bluetooth, NFC+ WiFi ad-hoc or WiFi-Direct method, these two methods complete the pairing through near-field sensing, and then transmit large data through Bluetooth or WiFi ad-hoc or WiFi-Direct, in which the transmission of large data is the local file directly Transmission in the past, there is a problem of unstable transmission

[0067] Based on the first embodiment, a second embodiment of the data transmission method based on near field communication of the present invention is proposed. In this embodiment, after step S30, it also includes:

[0068] Step S50, when the second device receives the file link address, it sends information of successful reception to the first device.

[0069] When the second device receives the file link address, it sends a message of successful reception to the first device. After receiving the message of successful reception, the first device can determine that the second device has received the file link address it sent. A time interval can be preset. If the first device does not receive the successful reception information fed back by the second device within the preset time interval, it can send a prompt message to the user, prompting the user to re-send the file link to the second device. address, after receiving the prompt information, the user triggers the near fiel...

Abstract

The invention relates to a data transmission method and system based on near-field communication. After the network connection is established between a first device and a second device through near-field communication, the first device generates only one link address of a file to be transmitted according to the local address of the file to be transmitted, the IP of the first device and terminal information and sends the generated link address to the second device in the manner of near-field communication, and the second device can download the file to be transmitted according to the received link address of the file to be transmitted optionally. The file can be transmitted stably, and the file can be re-downloaded when the current download fails; when the file connecting address is a media source, the file to be transmitted can be played directly online, the filed is not required to be downloaded to the second device to play, and more diverse functions are provided.

Description

technical field [0001] The present invention relates to the technical field of near field communication, in particular to a data transmission method and system based on near field communication. Background technique [0002] NFC (Near Filed Communication, near field communication), also known as short-range wireless communication, is a short-distance high-frequency wireless communication technology that performs non-contact point-to-point data transmission and exchange between operating devices. At present, more and more mobile devices have been installed with NFC modules, making the application of NFC gradually popular. [0003] However, since near-field communication requires short distances and transmits data through near-field sensing, only a small amount of data can be transmitted in terms of data transmission. Of course, there are currently some improvement solutions, specifically: NFC+Bluetooth, NFC+ WiFi ad-hoc or WiFi-Direct method, these two methods complete the p...
