4. The mobile terminal of claim 1, wherein the controller is further configured not to switch the first mode to the second mode when at least one of the switching signal is not received and an authentication procedure for the second mode is not validly performed.

5. The mobile terminal of claim 1, wherein if the attempt to switch to the second mode fails and the specific application is executable only in the first mode, the controller is further configured to prohibit the execution of the specific application in the first mode, and

wherein if the attempt to switch to the second mode fails and the specific application is executable in both of the first mode and the second mode, the controller is further configured to allow the execution of the specific application in the first mode but to restrict information from being provided based on the specific application being executed in the first mode.

6. The mobile terminal of claim 1, wherein the controller is further configured to prohibit the execution of specific applications among a plurality of applications that can be executed in the first mode except a basic application supporting a basic terminal action, when the attempt to switch to the second mode fails.

7. The mobile terminal of claim 1, wherein if the attempt to switch to the second mode fails, the specific application is currently executing and the specific application can only be executed in first mode, the controller is further configured to terminate the execution of the specific application, and

wherein if the currently executing specific application is executable in both of the first and second modes, the controller is further configured to restrict information provided by the currently executing specific application despite maintaining the executing of the first mode.

8. The mobile terminal of claim 1, wherein if the attempt to switch to the second mode fails, the controller is further configured to control the display unit to display an announcement window for announcing the second mode can not be switched to and provide an option for again trying to switch to the second mode.

9. The mobile terminal of claim 1, wherein if the attempt to switch to the second mode fails, the controller is further configured to control the display unit to display at least one or more application indicators indicating at least one or more applications that can be executed in the first mode or not to display at least one or more display application indicators indicating at least or more applications than can not be executed in the first mode.

10. The mobile terminal of claim 1, wherein the switching signal is generated in at least one of 1) when receiving an input of the switching signal, 2) when a current terminal location is located within a specific place corresponding to the second mode, 3) when a current time belongs to a specific time corresponding to the second mode, 4) when transceiving data with a counterpart terminal corresponding to the second mode, and 5) when accessing a specific network corresponding to the second mode.

11. The mobile terminal of claim 1, wherein the controller is further configured to switch back to the first mode from the second mode by reactivating the first mode and deactivating the second mode when a terminal operation corresponding to the switching signal is terminated after switching to the second mode.

12. The mobile terminal of claim 11, wherein if information on the specific application is included in the switching signal, the controller is further configured to execute the specific application after switching to the second mode.

13. 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, via a memory of the mobile terminal, at least first and second operating systems including at least first and second modes, respectively;

executing, via a controller of the mobile terminal, the first operating system and activating the first mode corresponding to the first operating system;

displaying, via a display unit of the mobile terminal, a first information screen corresponding to the activated first mode;

receiving, via the controller, a switching signal indicating the first mode is to be switched to the second mode;

attempting, via the controller, to switch to the second mode based on the received switching signal; and

restricting, via the controller, a specific application executing in the first mode when the second mode is not switched to.

14. The method of claim 13, wherein the first and second modes are discriminated from each other by at least one of a mode indicator, a database storage region, an operating system, a user access authority, a content configuration, a data configuration and an application feature.

15. The method of claim 14, wherein when the first and second modes respectively correspond to first and second database storage regions, the method further comprises preventing information stored in the first database storage region from being used in the second mode and preventing information stored in the second database storage region from being used in the first mode, or preventing selective information stored in the first or second database storage regions from being used in the first or second modes.

16. The method of claim 13, further comprising:

not switching, via the controller, the first mode to the second mode when at least one of the switching signal is not received and an authentication procedure for the second mode is not validly performed.

17. The method of claim 13, wherein if the attempt to switch to the second mode fails and the specific application is executable only in the first mode, the method further comprises prohibiting the execution of the specific application in the first mode, and

wherein if the attempt to switch to the second mode fails and the specific application is executable in both of the first mode and the second mode, the method further comprises allowing the execution of the specific application in the first mode but restricting information from being provided based on the specific application being executed in the first mode.

18. The method of claim 13, further comprising:
