Mobile terminal and mode controlling method therein

1. A mobile terminal, comprising:

a communication unit configured to communicate with at least one external terminal;

a memory configured to store at least first and second operating systems including at least first and second modes, respectively; and

a controller configured to display, in a first display region of a display unit of the mobile terminal, a first application indicator corresponding to a first application executable in the first mode using the first operating system and that can be activated by selecting the first application indicator, and to display, in a second display region, a second application indicator corresponding to a second application executable in the second mode using the second operating system and that can be activated by selecting the second application indicator,

wherein the first and second application indicators indicate whether the applications are executable in the first mode or the second mode, or executable in both the first and second modes,

wherein the controller is further configured to receive a selection signal indicating a selecting of the first application indicator in the first display region and a moving of the first application indicator to the second display region, and

wherein the controller is further configured to determine if the first application corresponding to the first application indicator can be executed in the second mode.

2. The mobile terminal of claim 1 , wherein the controller is further configured to execute the first application in the first mode and display the executing first application in the first region when the first application indicator is selected, and to execute the second application in the second mode and display the executing second application in the second display region when the second application indicator is selected.

3. The mobile terminal of claim 1 , wherein when the first application can be executed in the second mode, the controller is further configured to move or copy the first application indicator from the first display region to the second display region, and designate the first application as a common application executable in both the first and second modes when the first application indicator is copied to the second display region and to designate the first application as a second mode application executable only in the second mode when the first application indicator is moved to the second display region.

4. The mobile terminal of claim 1 , wherein the controller is further configured to selectively use data corresponding to the first application when the first application is executed in the second mode based on an authentication procedure.

5. The mobile terminal of claim 1 , wherein if the first application cannot be executed in the second mode, the controller is further configured to access an external server to retrieve at least one application that is similar to the first application and that can be executed in the second mode.

6. The mobile terminal of claim 1 , wherein the controller is further configured to distinctively display the first application indicator in the first display region from other application indicators to indicate the first application can be executed in the second mode.

7. The mobile terminal of claim 1 , wherein the controller is further configured to display a plurality of first mode identification numbers indicating a plurality of first modes, and display a plurality of second mode identification numbers indicating a plurality of second modes, and

wherein the selection signal indicates a selecting and moving of the first application indicator or the second application indicator to one of the first and second mode identification numbers.

8. The mobile terminal of claim 1 , wherein the first mode corresponds to a private mode of a user using the mobile terminal and the second mode corresponds to a business mode for a business associated with the user.

9. The mobile terminal of claim 1 , wherein the first and second application indicators include one of a widget and an icon.

10. A method of controlling a mobile terminal, the method comprising: allowing, via a communication unit of the mobile terminal, communication with at least one external terminal;

storing, in a memory of the mobile terminal, at least first and second operating systems including at least first and second modes, respectively;

displaying in a first display region of a display unit of the mobile terminal a first application indicator corresponding to a first application executable in the first mode using the first operating system and that can be activated by selecting the first application indicator;

displaying in a second display region of the display unit, a second application indicator corresponding to a second application executable in the second mode using the second operating system and that can be activated by selecting the second application indicator;

receiving a selection signal indicating a selecting of the first application indicator in the first display region and a moving of the first application indicator to the second display region; and

determining, via the controller, if the first application corresponding to the first application indicator can be executed in the second mode,

wherein the first and second application indicators indicate whether the applications are executable in the first mode or the second mode, or executable in both the first and second modes.

11. The method of claim 10 , further comprising:

executing, via a controller of the mobile terminal, the first application in the first mode and displaying the executing first application in the first region when the first application indicator is selected; and

executing, via the controller, the second application in the second mode and display the executing second application in the second display region when the second application indicator is selected.

12. The method of claim 10 , wherein when the first application can be executed in the second mode, the method further comprises:

moving or copying the first application indicator from the first display region to the second display region;

designating the first application as a common application executable in both the first and second modes when the first application indicator is copied to the second display region; and

designating the first application as a second mode application executable only in the second mode when the first application indicator is moved to the second display region.

13. The method of claim 10 , further comprising: selectively using data corresponding to the first application when the first application is executed in the second mode based on an authentication procedure.

14. The method of claim 10 , wherein if the first application cannot be executed in the second mode, the method further comprises:

access, via the communication unit, an external server to retrieve at least one application that is similar to the first application and that can be executed in the second mode.

15. The method of claim 10 , further comprising:

distinctively displaying the first application indicator in the first display region from other application indicators to indicate the first application can be executed in the second mode.

16. The method of claim 10 , further comprising:

displaying a plurality of first mode identification numbers indicating a plurality of first modes; and

displaying a plurality of second mode identification numbers indicating a plurality of second modes,

wherein the selection signal indicates a selecting and moving of the first application indicator or the second application indicator to one of the first and second mode identification numbers.

17. The method of claim 10 , wherein the first mode corresponds to a private mode of a user using the mobile terminal and the second mode corresponds to a business mode for a business associated with the user.

18. The method of claim 10 , wherein the first and second application indicators include one of a widget and an icon.
