Abstract

A terminal can include a wireless charger configured to wirelessly receive a power signal from a charging pad to charge power; and a controller configured to control an incoming call notification mode to be changed from a vibration mode to a bell sound mode or silent mode when an event is generated on the charging pad.

Claims

1. A terminal, comprising:

a wireless charger configured to wirelessly receive a power signal from a wireless power transmitter to charge power; and

a controller configured to detect a wireless power signal and control an incoming call notification mode to be changed from a vibration mode to an audible mode or a silent mode when an event is generated on the wireless power transmitter.

2. The terminal of claim 1, wherein the controller controls a display window for changing a charging mode or notifying a current charging mode state to be displayed based on a preset charging mode state when receiving the power signal from the wireless power transmitter.

3. The terminal of claim 2, wherein the controller controls the display window for changing a charging mode to be displayed when the preset charging mode is a wired charging mode, and the display window for notifying a current charging mode state to be displayed when the preset charging mode is a wireless charging mode.

4. The terminal of claim 1, further comprising:

a display unit,

wherein the controller controls the display unit to display a display window for changing the incoming call notification mode.

5. The terminal of claim 1, wherein the event generation is any one of an incoming call reception, a message reception, and a wireless charging start.

6. The terminal of claim 1, wherein the wireless charger charges power through an induction method.

7. The terminal of claim 1, further comprising:

a wireless communication unit,

wherein the controller controls the wireless communication unit to change the incoming call notification mode to the silent mode and transmit a message for notifying the event generation to the wireless power transmitter.

8. The terminal of claim 7, wherein the message is transmitted to the wireless power transmitter through a Bluetooth communication method.

9. The terminal of claim 7, wherein the controller controls the wireless communication unit to receive a response to the message from the wireless power transmitter.

10. The terminal of claim 9, wherein the controller controls a speaker phone to be activated when receiving a response to the message from the wireless power transmitter, and the event generation is an incoming call reception.

11. The terminal of claim 1, wherein the controller controls the changed audible mode or silent mode to be restored to the vibration mode when the wireless power signal is no longer detected.

12. A wireless charging method, the method comprising:

wirelessly receiving a power signal from a wireless power transmitter;

changing, by a terminal, an incoming call notification mode from a vibration mode to an audible mode or a silent mode when an event is generated on the wireless power transmitter; and

wirelessly charging a battery using the received power signal.

13. The method of claim 12, further comprising:

checking whether a preset charging mode is a wired charging mode or wireless charging mode; and

displaying a display window for changing the preset charging mode or notifying a current charging mode state according to the results of the checking step.

14. The method of claim 13, wherein the display window for changing a charging mode is displayed when the preset charging mode is a wired charging mode, and the display window for notifying a current charging mode state is displayed when the preset charging mode is a wireless charging mode.

15. The method of claim 12, further comprising:

displaying a display window for changing the incoming call notification mode.

16. The method of claim 12, wherein the event generation is any one of an incoming call reception, a message reception, and a wireless charging start.

17. The method of claim 12, wherein the wirelessly charging step charges power through an induction method.

18. The method of claim 12, further comprising:

changing the incoming call notification mode to the silent mode and transmitting a message for notifying the event generation to the wireless power transmitter.

19. The method of claim 18, further comprising:

receiving a response to the message from the wireless power transmitter.

20. The method of claim 19, further comprising:

activating a speaker phone when the event generation is an incoming call reception.

21. The method of claim 12, further comprising:

restoring the changed audible mode or silent mode to the vibration mode when charging has been stopped or completed.
