Abstract

In a mobile terminal, while a payment mode in which payment is available to be performed by a payment unit, execution of a function other than the function related to the payment is limited.

First claim

What is claimed is:

1. A mobile terminal comprising:
a wireless communication unit configured to perform wireless communication with a settlement terminal;
a display comprising a touch screen; and
a controller configured to:
cause the display to display a graphic object corresponding to a payment unit;
enter a payment mode in which a pending payment is available to be paid by the payment unit when user authentication information received with respect to the payment unit matches preset authentication information;
execute a first function related to payment by the payment unit during the payment mode;
limit execution of a second function that is not related to payment in response to a request to execute the second function received while the payment mode is being maintained, wherein the request to execute the second function comprises a touch received in a display area other than an area of the display in which the graphic object is displayed, and the second function is a function specified by user setting among functions executable in the mobile terminal;
cause the wireless communication unit to perform wireless communication with a preset external device wearable on a body part;
cause the wireless communication unit to transmit notification information indicating a specific state of the mobile terminal to the preset external device when the payment mode is entered;
cause the wireless communication unit to transmit a signal requesting signature information or the user authentication information necessary for executing the first function to the preset external device in the payment mode; and
execute the first function in response to the signature information or the user authentication information received from the external device in response to the signal.

2. The mobile terminal of claim 1 , wherein:
the payment mode is maintained for a set period of time such that the payment mode expires when the set period of time lapses; and
the first function cannot be executed after the expiration of the payment mode.

3. The mobile terminal of claim 2 , wherein the controller is further configured to enter the payment mode in response to or following a touch input applied to the touch screen for setting the period of time, the touch input applied after it is determined that the user authentication information matches the preset authentication information.

4. The mobile terminal of claim 3 , wherein the period of time is set based on at least one of a length of the touch input on the touch screen, a direction of the touch input, or a duration of the touch input.

5. The mobile terminal of claim 2 , wherein:
the first function includes a function of payment by the payment unit corresponding to the graphic object; and
the controller is further configured to cause the wireless communication unit to transmit a wireless signal including information regarding the payment unit to the settlement terminal when the function of payment by the payment unit is executed.

6. The mobile terminal of claim 5 , wherein the controller is further configured to:
cause the display to display an activation region in at least a portion of the touch screen when the payment mode is entered; and
cause the wireless communication unit to transmit the wireless signal to the settlement terminal in response a touch input applied to the activation region.

7. The mobile terminal of claim 5 , wherein the controller is further configured to cause the wireless communication unit to receive information regarding completion of the payment by the payment unit when the execution of the first function is completed such that further execution of at least the first function or the second function is limited after the payment is completed even before the set period of time lapses.

8. The mobile terminal of claim 2 , wherein:
the first function includes a function of maintaining the payment mode; and
the controller is further configured to maintain the payment mode even after the set period of time lapses when at least one of an event for switching the payment unit corresponding to the graphic object or an event for extending the set period of time occurs before the set period of time lapses.

9. The mobile terminal of claim 8 , wherein the event for switching the payment unit occurs when information regarding completion of payment by the payment unit is not received by the wireless communication unit within a preset period of time after the function of payment by the payment unit corresponding to the graphic object is executed.

10. The mobile terminal of claim 8 , wherein when the event for switching the payment unit corresponding to the graphic object occurs, the controller is further configured to:
switch the graphic object to a new graphic object corresponding to a new payment unit;
cause the display to display the new graphic object; and
reset a period of time starting from a point in time at which the new graphic object is displayed on the touch screen.

11. The mobile terminal of claim 1 , wherein the controller is further configured to:
determine a first touch, which is received at a predetermined area of the graphic object during the payment mode, as a request to execute the first function; and
determine a second touch, which is received at an area other than the predetermined area of the graphic object during the payment mode, as a request to execute the second function.

12. The mobile terminal of claim 1 , wherein the controller is further configured to:
sense that strength of a wireless signal received from the preset external device is decreased by a value that is equal to or greater than a preset ratio based on the wireless communication with the preset external device; and
cause the wireless communication unit to transmit notification information indicating a relative position of the mobile terminal with respect to the preset external device to the preset external device.

13. The mobile terminal of claim 11 , wherein in response to the second touch, the controller is further configured to cause the wireless communication unit to transmit, to the preset external device, notification information indicating that the second touch has been received.

14. The mobile terminal of claim 1 , wherein the controller is further configured to:
execute the first function in response to a control command related to payment by the payment unit, the control command received from the preset external device via the wireless communication unit.

15. The mobile terminal of claim 1 , wherein the controller is further configured to execute the second function when preset authentication is performed by a user during the payment mode.

16. The mobile terminal of claim 15 , wherein the controller is further configured to end the payment mode when the second function is executed.

17. A method for controlling a mobile terminal, the method comprising:
performing wireless communication with a settlement terminal;
displaying a graphic object corresponding to a payment unit on a touch screen;
entering a payment mode in which a pending payment is available to be paid by the payment unit when user authentication information received with respect to the payment unit matches preset authentication information;
limiting execution of a second function that is not related to payment in response to a request to execute the second function received while the payment mode is being maintained, wherein the request to execute the second function comprises a touch received in a display area other than an area of the touch screen in wh
