Abstract

A method for data sharing is provided. The method includes: searching, by a first terminal, for multiple nearby terminals, and establishing wireless connections with the discovered nearby terminals, displaying on the display interface of the first terminal the nearby terminals already wirelessly connected to the first terminal and a transmittable file stored in the first terminal or the nearby terminals, and receiving by the first terminal a file-transmission command and transmitting or receiving a file to or from the nearby terminals. A system for data sharing is also provided. By the above means, operations based on the present disclosure are simple and fast, enabling interconnections of mobile terminals within a close range, a mobile terminal can transmit a file synchronously to multiple terminals for data transmission, and the terminals can share data therebetween, which thus profoundly enhances the user experience.

First claim

The invention claimed is:

1. A method for data sharing, comprising:
receiving, by a first terminal, a registration command;
searching, by the first terminal, when the registration command is verified to be successful, which indicates that the first terminal is successfully registered in a system for data sharing, for a plurality of nearby terminals which are successfully registered in the system, and establishing wireless connections with the nearby terminals discovered, where the first terminal establishes a point-to-point wireless connection with a nearby second terminal discovered, and proceeds to establish a wireless connection with a third terminal via a point-to-point wireless connection between the second terminal and the third terminal;
displaying, by the first terminal, on its display interface the nearby terminals already wirelessly connected to the first terminal and a transmittable file stored in the first terminal or the nearby terminals as figures;
receiving, by the first terminal, a command of transmitting the file, and transmitting or receiving the file to or from the nearby terminals, wherein the file is a picture file, the first terminal performs face recognition on faces in a picture file saved by the first terminal to determine whether a face of the user of each of the nearby terminals is present in the picture file, and when the face of the user of a nearby terminal is present in the picture file, the picture file is transmitted to the terminal held by the user with the face present in the picture file.

2. The method according to claim 1 , wherein the wireless connections comprise at least one of a WIFI Direct connection, a Wi-Fi connection, and a Bluetooth connection.

3. The method according to claim 1 , wherein the displaying by the first terminal on its display interface the nearby terminals comprises:
displaying, by the first terminal, on its display interface at least one of a device name, a device type, a user avatar and a user nickname of each of the nearby terminals.

4. A method for data sharing, comprising:
receiving, by a first terminal, a registration command;
searching, by the first terminal, when the registration command is verified to be successful, which indicates that the first terminal is successfully registered in a system for data sharing, for a plurality of nearby terminals which are successfully registered in the system, and establishing wireless connections with the nearby terminals discovered;
displaying, by the first terminal, on its display interface the nearby terminals already wirelessly connected to the first terminal and a transmittable file stored in the first terminal or the nearby terminals;
receiving, by the first terminal, a command of transmitting the file, and transmitting or receiving the file to or from the nearby terminals, wherein the file is a picture file, the first terminal performs face recognition on faces in a picture file saved by the first terminal to determine whether a face of the user of each of the nearby terminals is present in the picture file, and when the face of the user of a nearby terminal is present in the picture file, the picture file is transmitted to the terminal held by the user with the face present in the picture file.

5. The method according to claim 4 , the step of searching by the first terminal for the nearby terminals and establishing the wireless connections with the nearby terminals discovered comprises:
establishing, by the first terminal, a point-to-point wireless connection with a nearby second terminal discovered, and proceeding to establish a wireless connection with a third terminal via a point-to-point wireless connection between the second terminal and the third terminal.

6. The method according to claim 4 , wherein the wireless connections comprise at least one of a WIFI Direct connection, a Wi-Fi connection, and a Bluetooth connection.

7. The method according to claim 4 , wherein the nearby terminals and the transmittable file are displayed as figures on the display interface of the first terminal.

8. The method according to claim 4 , wherein the displaying by the first terminal on its display interface the nearby terminals comprises:
displaying, by the first terminal, on its display interface at least one of a device name, a device type, a user avatar and a user nickname of each of the nearby terminals.

9. A system for data sharing, comprising a first terminal and a plurality of nearby terminals wirelessly connected to the first terminal, wherein a display interface of the first terminal displays the nearby terminals wirelessly connected to the first terminal and a transmittable file stored in the first terminal or the nearby terminals, and the first terminal is configured to receive a command of transmitting the file and transmit or receive the file to or from the nearby terminals, wherein the file is a picture file, the first terminal performs face recognition on faces in a picture file saved by the first terminal to determine whether a face of the user of each of the nearby terminals is present in the picture file, and when the face of the user of a nearby terminal is present in the picture file, the picture file is transmitted to the terminal held by the user with the face present in the picture file;
wherein the first terminal comprises:
a communication module connected to the nearby terminals and configured to receive a registration command and transmit or receive the file to or from the nearby terminals;
a processing module connected to the communication module, and configured to verify whether the registration command succeeds, and, after verifying that the registration command succeeds, which indicates that the first terminal is successfully registered in a system for data sharing, search for the nearby terminals which are successfully registered in the system and establish wireless connections with the nearby terminals discovered.

10. The system according to claim 9 , wherein the first terminal comprises:
a display module connected to the processing module and configured to display the nearby terminals already wirelessly connected to the communication module and a transmittable file stored in the first terminal or the nearby terminals.

11. The system according to claim 10 , wherein the communication module is further configured to establish a point-to-point wireless connection with a nearby second terminal discovered, and to proceed to establish a wireless connection with a third terminal via a point-to-point wireless connection between the second terminal and the third terminal.

12. The system according to claim 10 , wherein the display module displays, on the display interface of the first terminal, at least one of a device name, a device type, a user avatar and a user nickname of each of the nearby terminals.
