Abstract

The present disclosure provides a wireless charging control method. The wireless charging control method in an apparatus having a wireless power reception module, includes sensing an event in a wireless charging mode, determining whether the sensed event is a predetermined wireless-charging indirect-associated event, when the sensed event is a predetermined wireless-charging indirect-associated event, identifying a wireless charging operation corresponding to the wireless-charging indirect-associated event and controlling wireless charging according to the identified wireless charging operation.

Claims

1. A non-transitory storage medium storing instructions that, when executed by a processor, in an apparatus having a wireless power reception module, cause the processor to:

sense an event in a wireless charging mode;

determine whether the sensed event is a predetermined event;

when the sensed event is the predetermined event, identify a wireless charging operation corresponding to the predetermined event; and

control wireless charging according to the identified wireless charging operation,

wherein the predetermined event corresponds to at least occurrence of a call event on the apparatus.

2. The non-transitory storage medium of claim 1, wherein the predetermined event further corresponds to at least one of a user event and a temperature change event.

3. The non-transitory storage medium of claim 1, wherein the wireless charging operation is at least one of a wireless charging stop, a wireless charging standby, and a wireless charging current level change.

4. The non-transitory storage medium of claim 3, wherein controlling the wireless charging according to the identified wireless charging operation comprises generating a wireless charging control signal according to the wireless charging operation and transmitting the generated wireless charging control signal to a wireless power transmission apparatus.

5. The non-transitory storage medium of claim 3, wherein controlling the wireless charging according to the identified wireless charging operation controls the wireless power reception module according to the wireless charging operation.

6. The non-transitory storage medium of claim 1, wherein the call event is an event using a receiver.

7. The non-transitory storage medium of claim 6, wherein the call event using the receiver occurs by sensing human body proximity.

8. The non-transitory storage medium of claim 2, wherein, when the predetermined event further corresponds to the user input event, controlling the wireless charging corresponds to one of a wireless charging stop, a wireless charging standby, and a wireless charging current level reduction.

9. The non-transitory storage medium of claim 8, wherein the user input event corresponds to at least one of a finger touch input, a finger proximity input, an electronic pen touch input, and an electronic pen proximity input.

10. The non-transitory storage medium of claim 1, wherein, when entering the wireless charging mode, an operation environment of a predetermined function associated with a wireless charging control is adjusted according to the wireless charging mode.

11. The non-transitory storage medium of claim 10, wherein the predetermined function associated with wireless charging control is a call function, and the operation environment adjustment is to adjust a speaker call mode to have priority.

12. The non-transitory storage medium of claim 10, wherein the function associated with the wireless charging control corresponds to an input sensing processing function and the operation environment adjustment adjusts an input sensing threshold value to a predetermined input sensing threshold value at the time of wireless charging.

13. A non-transitory storage medium storing instructions that, when executed by a processor, cause the processor to:

when a wireless charging mode is performed, adjust an operation environment of a predetermined call function according to call reception into a speaker call mode;

determine whether a call reception event occurs while performing a wireless charging operation;

when the call reception event occurs, perform a call operation in the speaker call mode;

when a human proximity state is sensed while the call operation is being performed, stop the wireless charging operation and perform the call in a receiver call mode; and

when the human proximity state is not sensed while performing the call in the receiver call mode, start the wireless charging operation and perform the call in the speaker call mode.

14. The non-transitory storage medium of claim 13, wherein stopping the wireless charging operation further comprises requesting a charging stop to a wireless power transmission apparatus and turning off a wireless charging reception function.

15. A mobile terminal having a wireless charging function, the mobile terminal comprising:

a touch screen configured to perform a display function relating to output information and an input function;

a wireless power reception module configured to receive charging power provided from an external wireless power transmission apparatus;

a power supply unit configured to receive charging power provided from the wireless power reception module and generate internal operation power for the mobile terminal; and

a control unit configured to control operation of the mobile terminal by controlling respective functional units and, when a predetermined event occurs while a wireless charging operation is being performed, controls the wireless charging operation according to the predetermined event,

wherein the predetermined event corresponds to at least occurrence of a call event on the apparatus.

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

a mobile communication unit that performs wireless signal transmitting and receiving;

a proximity sensor for sensing object proximity; and

a temperature sensor for sensing a temperature,

wherein the predetermined event further corresponds to a user input event and a temperature change event, and the wireless charging operation corresponds to at least one of a wireless charging stop, a wireless charging standby, and a wireless charging current level change.

17. The mobile terminal of claim 16, wherein controlling the wireless charging by the control unit comprises generating a wireless charging control signal according to the wireless charging operation, transmitting the generated wireless charging control signal to the wireless power transmission apparatus, and controlling the wireless power reception module.

18. The mobile terminal of claim 16, wherein, when the wireless charging operation is performed, the control unit adjusts an operation environment of a predetermined function associated with a wireless charging control into a state according to a wireless charging mode.

19. The mobile terminal of claim 18, wherein the predetermined function associated with the wireless charging control corresponds to a call function, and the operation environment adjustment adjusts a speaker call mode to have priority.
