Embodiment 1

[0066] figure 1 The flow chart of the main method provided by Embodiment 1 of the present invention, such as figure 1 As shown, the method mainly includes the following steps:

[0067] Step 101: When the first mobile device and the second mobile device are within the effective distance of NFC, perform NFC pairing, and during the NFC pairing process, the first mobile device sends WIFI connection parameters and a file discovery list to the second mobile device.

[0068] NFC is a short-distance high-frequency wireless communication technology that allows non-contact point-to-point data transmission between electronic devices, and can be used to quickly and actively set up wireless networks. In the present invention, NFC is used to realize pairing between mobile devices. Actively set up subsequent WIFI connections, that is, exchange WIFI connection parameters.

[0069] Usually, the effective distance of NFC is 10 centimeters, and within 10 centimeters, NFC pairing can be complet...

Embodiment 2

[0081] The method provided by the present invention will be described in detail through Example 2 below. In this embodiment, taking the mobile phone as an example, assuming that the file on the mobile phone A is to be transferred to the mobile phone B, the mobile phone A and the mobile phone B are both in the waiting state, that is, the NFC function and the WIFI function of the mobile phone A and the mobile phone B have been activated , which is in the client mode by default, the corresponding method flow can be as follows figure 2 shown, including the following steps:

[0082] Step 201: When the mobile phone A is triggered by the user, enter the master mode.

[0083] If the user of mobile phone A wants to transfer files, he can trigger mobile phone A to enter the master mode by clicking a function button on the mobile phone or clicking the file to be transferred. After entering the master mode, mobile phone A waits for pairing requests from other mobile phones.

[0084] St...

Embodiment 3

[0120] image 3 A schematic structural diagram of a device installed in the first mobile device provided in Embodiment 3 of the present invention, as shown in image 3 As shown, the device mainly includes: an NFC module 301 , a WIFI module 302 and a file transfer module 303 .

[0121] When the NFC module 301 and another mobile device (ie, the second mobile device in Embodiment 1) are within the NFC effective distance, NFC pairing is performed, and the WIFI connection parameters and file discovery list are sent to the other mobile device during the NFC pairing process.

[0122] The WIFI module 302 establishes a WIFI connection with another mobile device using WIFI connection parameters.

[0123] The file transfer module 303 uses the WIFI connection to send one or more files in the file discovery list to another mobile device.

[0124] On this basis, the device may further include: a process control module 305 .

[0125] The process control module 305 is responsible for contr...

Abstract

The invention provides a method of point-to-point data transmission for a mobile device and a device. The method comprises the following steps that: a first mobile device and a second mobile device performs NFC pairing within the effective distance of NFC (Near-Field Communication), and the first mobile device sends wireless broadband (Wireless Fidelity(WIFI)) connection parameters and a file finding list to the second mobile device in the process of NFC pairing; and the first mobile device and the second mobile device utilize the WIFI connection parameters to build WIFI connection; and the first mobile device utilizes the WIFI connection to send one or more files in the file finding list to the second mobile device. The point-to-point data transmission for the mobile devices provided by the invention can achieve the objects of simple operation, increased effective distance, improved stability of connection and improved data transmission speed.

Description

【Technical field】 [0001] The invention relates to the technical field of network communication, in particular to a method and device for point-to-point data transmission of a mobile terminal. 【Background technique】 [0002] With the continuous development of mobile communication technology, users are increasingly dependent on mobile devices, and the demand for data transmission between mobile devices is increasing. Files in the memory of mobile devices are a solidified form of data. The most typical data transmission is file transfer. The file transfer between existing mobile devices is mainly realized through Bluetooth technology, but the file transfer based on Bluetooth technology has the following defects: [0003] First, the Bluetooth pairing process is too cumbersome. During the Bluetooth pairing process, one user needs to manually enter the pairing code on the mobile device, and the other user enters the same pairing code when connecting to establish a connection. Thi...
