Embodiment Construction

[0029] The terms "first" and "second" and the like in the present invention may describe various elements herein, but these elements are not limited by these terms. These terms are only used to distinguish one element from another element. For example, without departing from the scope of the present invention, a first terminal may be called a second terminal, and similarly, a second terminal may be called a first terminal. Both the first terminal and the second terminal are terminal devices, but they are not the same terminal device.

[0030] figure 1 It is a sequence diagram of a file transmission method, which is implemented by the first terminal and the second terminal. The method includes the following steps:

[0031] S202: The first terminal acquires a file download instruction.

[0032] In a specific implementation manner, the user runs the file transfer application on the first terminal, the application is provided with a download-related interactive control, and th...

Abstract

The invention relates to a file transmission method and system. The method comprises the steps that a first wireless local area network taking a first terminal as a wireless hotspot is established, and a first two-dimensional bar code stored with a hotspot name and an access password of the first wireless local area network is generated and displayed; a second terminal obtains the hotspot name and the access password of the first wireless local area network by scanning the first two-dimensional bar code and accesses the first wireless local area network through the hotspot name and the access password to establish connection with the first terminal; and the second terminal obtains a file selected by a user and sends the file to the first terminal. Through application of the method, the wireless local area network is established by utilization of the wireless hotspot of the first terminal; and the second terminal can transmit the file stored in the second terminal to the first terminal by accessing the wireless local area network. Even if under the condition that no external network exists, the file still can be transmitted. The limit of the external network is eliminated, thereby facilitating operations of a user.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a file transmission method and system. Background technique [0002] An interactive smart tablet refers to an integrated device that uses touch technology to manipulate the content displayed on the tablet and realize human-computer interaction. In application scenarios such as education and conferences, the size of the required interactive smart tablet is relatively large, and it is usually installed in a fixed position. Moreover, in application scenarios such as education and conferences, it is often necessary to reuse the same file in different classrooms or conference rooms. [0003] The way that the current interactive smart flat panel realizes file transfer is to store the files in the network server, and download the files to be used from the network server by accessing the network server on the interactive smart flat panel. However, this implementation is based on...
