Abstract

A data sharing method and a portable terminal are provided. The portable terminal is a first terminal having a first system and a second system which have a capability of operating a shared storage area. The method comprises: starting transmitting a file in the shared storage area to a second terminal by the first system; acquiring upload information of the file by the second system, when detecting that the first system fulfills a predetermined condition, during the transmission of the file in the shared storage area to the second terminal by the first system; and continuing the transmission of the file to the second terminal by the second system in accordance with the upload information. In the transmission of shared data according to the embodiments of the present disclosure, due to the two-system hybrid architecture of the terminal, one of the two systems may continue the transmission of the shared data if the transmission is interrupted by shut down or fault of the other one of the two systems, thereby the user experience in transmitting the shared data may be improved.

Claims

1. A data sharing method applicable in a first terminal, wherein the first terminal includes a first system and a second system which have a capability of operating a shared storage area directly accessible to each of the first and second systems, and the first and second systems having first and second hardware platforms, respectively, which can share hardware devices, the method comprising:

starting, by the first system, transmitting a file in the shared storage area to a second terminal;

detecting, by the first or second system, whether the first system fulfills a predetermined condition indicating or requiring stop of the file transmission by the first system, during the transmission of the file in the shared storage area to the second terminal by the first system; and

in response to detecting that the first system fulfills the predetermined condition;

acquiring, by the second system, upload information of the file comprising information about the file transmission by the first system; and

switching to the second system, and continuing, by the second system, the transmission of the file to the second terminal in accordance with the upload information;

wherein the first system is located within a first casing of the first terminal, and the second system and the shared storage area are located within a second casing of the first terminal; and

wherein detecting that the first system fulfills the predetermined condition comprises;

detecting, by the second system, a signal indicating that the first casing containing the first system is separated from the second casing.

2. The data sharing method of claim 1, wherein detecting that the first system fulfills the predetermined condition further comprises:

detecting, by the first system, that only the operation of transmitting the file to the second terminal is currently performed;

or

detecting, by the second system, that the first system enters an inactive state;

or

detecting, by the first system, that a transmission fault occurs during the transmission of the file.

3. The data sharing method of claim 1, before transmitting the file in the shared storage area to the second terminal by the first system, further comprising:

associating the first terminal with the second terminal by starting a sharing client software.

4. The data sharing method of claim 1, before transmitting the file in the shared storage area to the second terminal by the first system, further comprising:

marking the file, by the first system, in accordance with a user-input sharing command; and

saving the file and mark information into the shared storage area, wherein the mark information includes partition, catalogue, and file name of the file in the shared storage area as well as an identification of the second terminal.

5. The data sharing method of claim 4, wherein transmitting the file in the shared storage area to the second terminal by the first system comprises:

reading, by the first system, the mark information in the shared storage area; and

acquiring the file in accordance with the mark information, and transmitting the file to the second terminal in accordance with the identification of the second terminal.

6. The data sharing method of claim 1, when detecting that the first system fulfills the predetermined condition, further comprising:

recording, by the first system, the upload information of the file into the shared storage area, wherein the upload information includes progress and amount of upload.

7. The data sharing method of claim 1, wherein the second terminal comprises a first system, a second system, and a shared storage area, the method further comprises:

storing, by the first system, a received shared data into the shared storage area of the second terminal, when the first system of the second terminal is in an active state; and

storing, by the second system, the received shared data into the shared storage area of the second terminal, when the first system of the second terminal exits the active state.

8. A first terminal comprising a first system and a second system which have capability of operating a shared storage area directly accessible to each of the first and second systems, wherein:

the first and second systems have first and second hardware platforms, respectively, which can share hardware devices;

the first system comprises a first transmission unit configured to transmit a file in the shared storage area to a second terminal;

at least one of the first and second system comprises a detecting unit configured to detect whether the first system fulfills a predetermined condition indicating or requiring stop of the file transmission by the first system, during the transmission of the file in the shared storage area to the second terminal by the first system; and

the second system further comprises an acquisition unit and a second transmission unit,

wherein in response to the detecting unit detecting that the first system fulfills the predetermined condition, the acquisition unit acquires upload information of the file comprising information about the file transmission by the first system, and the second transmission unit continues the transmission of the file to the second terminal in accordance with the upload information;

wherein the first system is located within a first casing of the first terminal, and the second system and the shared storage area are located within a second casing of the first terminal; and

wherein the detecting unit detects that the first system fulfills the predetermined condition by detecting a signal indicating that the first casing containing the first system is separated from the second casing.

9. The first terminal of claim 8, wherein the first system further comprises:

a marking unit configured to mark the file in accordance with a sharing command user inputted; and

a saving unit configured to save the file and mark information into the shared storage area, wherein the mark information includes the partition, catalogue, and file name of the file in the shared storage area as well as an identification of the second terminal.

10. The first terminal of claim 9, wherein the first transmission unit comprises:

a mark reading unit configured to read the mark information in the shared storage area; and

a file sending unit configured to acquire the file in accordance with the mark information, and transmit the file to the second terminal in accordance with the identification of the second terminal.

11. The first terminal of claim 8, wherein the first system further comprises a recording unit configured to record the upload information of the file into the shared storage area when the detecting unit detects that the first system fulfills the predetermined condition.
