Detailed Description
The principles and spirit of the present application will be described with reference to a number of exemplary embodiments. It should be understood that these embodiments are given solely for the purpose of enabling those skilled in the art to better understand and to practice the present application, and are not intended to limit the scope of the present application in any way. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
As will be appreciated by one skilled in the art, embodiments of the present application may be embodied as a system, apparatus, device, method or computer program product. Accordingly, the present disclosure may be embodied in the form of: entirely hardware, entirely software (including firmware, resident software, micro-code, etc.), or a combination of hardware and software.
Although the flow described below includes operations that occur in a particular order, it should be appreciated that the processes may include more or less operations that are performed sequentially or in parallel (e.g., using parallel processors or a multi-threaded environment).
It will be understood that when an element is referred to as being "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
For data transmission between mobile terminals, in the prior art, short messages and telephone calls are usually adopted or a timely communication software mode is adopted to realize data transmission between the mobile terminals, and certain short message charges and telephone charges are correspondingly generated or certain flow resources are required to be used by adopting the mode, so that under the conditions of mobile terminal arrearage or mobile terminal flow shortage and the like, data transmission between the mobile terminals cannot be conveniently realized in real time.
In addition, for data transmission between the mobile terminal and the computer, in the prior art, the USB interface of the mobile terminal end and the USB interface of the computer end are usually connected through a data line, so as to implement data transmission between the mobile terminal and the computer. And the USB interface protocol is adopted, so that the data transmission is slow and the transmission efficiency is low due to the limitation of the transmission rate when the data volume to be transmitted is large. In addition, on one hand, because the types of data lines which can be connected by the mobile terminals with different types are different, if the user does not carry the data lines with the corresponding types, the data transmission cannot be carried out in time. On the other hand, the data line has the characteristic of easy loss, so that the service life is short, and the data transmission by adopting the data line is inconvenient and impractical.
In a specific scene, because the mobile terminal body is provided with the USB interface, the USB interface is easy to deposit dust, is difficult to clean and is not attractive, so that the current mobile terminal gradually develops towards a non-porous design, namely the mobile terminal body is not provided with the USB interface. If the mobile terminal body is not provided with the USB interface, the technical scheme in the prior art cannot be used for carrying out data transmission through the mobile terminal effectively and conveniently in real time.

The machine body of the first terminal is not provided with the USB interface, so that the first terminal is more attractive in appearance, and the problem that the USB interface is easy to accumulate dust and is difficult to clean is effectively avoided.
The position information can be used for representing the current positions of the first terminal and the second terminal, and the position information of the first terminal and the second terminal can be determined by satellite positioning (GPS, Beidou satellite navigation system, European Union Galileo satellite navigation system, Russian global navigation satellite system), mobile base station positioning, WIFI auxiliary positioning, AGPS positioning and the like. In an embodiment, the location information may be determined by a Global Positioning System (GPS) in the first terminal and the second terminal, and the location information may specifically be longitude and latitude coordinates, and of course, other representations may also be adopted, for example: the expression forms of XX streets in the stupid district of suzhou city in Jiangsu province can be determined according to actual conditions, and the present application does not limit the present invention.

In an embodiment, the distance between the first terminal and the second terminal may be a distance between a geometric center point of the first terminal and a geometric center point of the second terminal, or a distance between a device in the first terminal and a device in the second terminal, which may be determined according to practical situations, and is not limited in this application. The distance between the first terminal and the second terminal may be a linear distance, a vertical distance, or a horizontal distance between the first terminal and the second terminal, and which distance calculation method is specifically adopted may be determined according to an actual situation, which is not limited in the present application.
In one embodiment, whether the distance between the first terminal and the second terminal is smaller than the preset threshold may be determined by a preset processor in the first terminal, but it is understood that whether the distance between the first terminal and the second terminal is smaller than the preset threshold may also be determined by other manners, such as: the judgment can be performed by a processor preset in the second mobile terminal, or by a third terminal independent from the first terminal and the second terminal, where the third terminal may be a mobile terminal, a server, or the like, and may be determined specifically according to an actual situation, which is not limited in this application.
