Mobile terminal and controlling method thereof

1. A mobile terminal comprising:

a display configured to display information;

a short range communication module configured to exchange a signal with an external control device; and

a controller configured to:

receive the signal from the external control device,

determine a context at a timing point of receiving the signal, and

control an operation corresponding to the signal to be performed in the determined context,

wherein the operation includes an activation/deactivation of a lock mode of the mobile terminal and an indicating of a location of the mobile terminal,

wherein after the lock mode has been entered in response to a deviation from a threshold distance, the lock mode is automatically cancelled when a distance between the mobile terminal and the external control device becomes smaller than the threshold distance, and

wherein the controller is further configured to output a sound or vibration, when the indicating of the location of the mobile terminal is performed in response to a manipulation of the external control device.

2. The mobile terminal of claim 1 , wherein the controller is further configured to determine a distance from the external control device by measuring a strength of the signal received from the external control device.

3. The mobile terminal of claim 2 , wherein the context comprises at least one of a type of an application activated at the signal received timing point, the determined distance and activation/deactivation of the lock mode.

4. The mobile terminal of claim 3 , wherein the controller is further configured to determine the activation/deactivation of the display depending on the determined distance.

5. A mobile terminal comprising:

a first camera and a second camera arranged in different directions on the mobile terminal;

a display configured to display information;

a short range communication module configured to exchange a signal with an external control device; and

a controller configured to:

receive the signal from the external control device,

determine a context at a timing point of receiving the signal, and

control an operation corresponding to the signal to be performed in the determined context,

wherein the operation includes at least one of activation/deactivation of the display, an activation/deactivation of a lock mode of the mobile terminal, a volume operation and a camera operation, and

wherein if the received signal includes a command for activating the camera operation, the controller is further configured to determine a camera to activate using a preview image taken via each of the first camera and the second camera.

6. The mobile terminal of claim 5 , wherein when the command for activating the camera operation is received, the controller is further configured to activate the camera operation irrespective of activation/deactivation of the lock mode.

7. The mobile terminal of claim 1 , wherein the controller is further configured to display information on the operation corresponding to the signal on the display unit.

8. The mobile terminal of claim 1 , wherein the short range communication module is further configured to communicate with the external control device by one of BLUETOOTH, NFC (near field communication), RFID (radio frequency identification), IrDA (infrared data association), UWB (ultra wideband) and ZIGBEE.

9. A method of controlling a mobile terminal, the method comprising:

pairing, via a short range communication module of the mobile terminal, an external control device with the mobile terminal; and

receiving, via a controller of the mobile terminal, a signal from the external control device;

determining, via the controller, a context at a timing point of receiving the signal; and

controlling, via the controller, an operation corresponding to the signal to be performed in the determined context,

wherein the operation includes an activation/deactivation of a lock mode of the mobile terminal and an indicating of a location of the mobile terminal,

wherein after the lock mode has been entered in response to a deviation from a threshold distance, the lock mode is automatically cancelled when a distance between the mobile terminal and the external control device becomes smaller than the threshold distance, and

wherein the method further comprises outputting a sound or vibration, when the indicating of the location of the mobile terminal is performed in response to a manipulation of the external control device.

10. The method of claim 9 , further comprising:

determining, via the controller, a distance from the external control device by measuring a strength of the signal received from the external control device.

11. The method of claim 10 , wherein the context comprises at least one of a type of an application activated at the signal received timing point, the determined distance and activation/deactivation of the lock mode.

12. The method of claim 11 , further comprising:

determining, via the controller, the activation/deactivation of the display depending on the determined distance.

13. A method of controlling a mobile terminal, the method comprising:

pairing, via a short range communication module of the mobile terminal, an external control device with the mobile terminal; and

receiving, via a controller of the mobile terminal, a signal from the external control device;

determining, via the controller, a context at a timing point of receiving the signal;

controlling, via the controller, an operation corresponding to the signal to be performed in the determined context, wherein the operation includes at least one of an activation/deactivation of a display of the mobile terminal, an activation/deactivation of a lock mode of the mobile terminal, a volume operation and a camera operation; and

if the received signal includes a command for activating the camera operation, determining a camera to activate using a preview image taken via each of a first camera and a second camera arranged in different directions on the mobile terminal.

14. The method of claim 13 , wherein when the command for activating the camera application is received, the method further comprises activating the camera operation irrespective of activation/deactivation of the lock mode.

15. The mobile terminal of claim 1 , further comprising:

a first camera and a second camera arranged in different directions on the mobile terminal,

wherein the operation further includes an activation/deactivation of the display, and

wherein if the received signal includes a command for activating the camera operation, the controller is further configured to determine a camera to activate using a preview image taken via each of the first camera and the second camera.

16. The mobile terminal of claim 15 , wherein when the command for activating the camera operation is received, the controller is further configured to activate the camera operation irrespective of activation/deactivation of the lock mode.

17. The method of claim 9 , further comprising:

if the received signal includes a command for activating the camera operation, determining a camera to activate using a preview image taken via each of a first camera and a second camera arranged in different directions on the mobile terminal,

wherein the operation further includes an activation/deactivation of the display.

18. The method of claim 17 , wherein when the command for activating the camera application is received, the method further comprises activating the camera operation irrespective of activation/deactivation of the lock mode.
