Abstract

A method of handling wireless charging authentication for an electronic device of a wireless charging system includes sending a first message to a controller of the wireless charging system to notify the controller that an authentication is required by a wireless charger of the wireless charging system; receiving a second message including authentication information from the controller; and sending a third message including the authentication information to the wireless charger, in order to satisfy the authentication.

Claims

1. A method of handling wireless charging authentication for an electronic device of a wireless charging system, comprising:

the electronic device sending a first message to a controller of the wireless charging system to notify the controller that an authentication is required by a wireless charger of the wireless charging system;

the electronic device receiving a second message comprising authentication information from the controller;

the electronic device sending a third message comprising the authentication information to the wireless charger, in order to satisfy the authentication; and

the electronic device receiving, from the wireless charger, a fourth message comprising information indicating whether the authentication is successful.

2. The method of claim 1, further comprising:

the electronic device receiving wireless power from the wireless charger before sending the third message comprising the authentication information to the wireless charger.

3. The method of claim 1, further comprising:

the electronic device stopping receiving power from the wireless charger and resending the third message or sending another message comprising the authentication information to the wireless charger after receiving the fourth message comprising information indicating that the authentication is failed.

4. The method of claim 1, further comprising:

the electronic device sending a fifth message to the controller to indicate whether the authentication is successful.

5. The method of claim 1, further comprising:

the electronic device receiving an indication indicating that the authentication is required by the wireless charger.

6. The method of claim 5, wherein the step of receiving the indication indicating that the authentication is required by the wireless charger comprises:

the electronic device receiving, from the wireless charger, a request message comprising information indicating that the authentication is required.

7. The method of claim 6, further comprising:

the electronic device sending a query message to the wireless charger to ask whether the authentication is required before receiving the request message.

8. The method of claim 5, wherein the step of receiving the indication indicating that the authentication is required by the wireless charger comprises:

the electronic device sending a sixth message to the wireless charger to request the wireless charger to adjust a parameter of wireless charging; and

the electronic device determining that the authentication is required by the wireless charger when detecting that the parameter does not change during a period of time.

9. The method of claim 1, further comprising:

the electronic device sending a seventh message to the wireless charger to request a time extension for the authentication.

10. The method of claim 1, wherein the authentication information comprises at least one of a security code, a password, full or partial of an identity of the controller, full or partial of an identity of the electronic device, an input to the controller, information indicating that a user of the controller has completed a certain operation on the controller, and a service code denoting a level of service that the wireless charger provides.

11. The method of claim 1, further comprising:

the electronic device storing the authentication information in a memory of the electronic device when receiving the second message from the controller.

12. A method of handling wireless charging authentication for a controller of a wireless charging system, comprising:

the controller receiving, from an electronic device of the wireless charging system, a first message which requests authentication information for an authentication required by a wireless charger of the wireless charging system;

the controller sending a second message comprising the authentication information to the electronic device; and

the controller receiving, from the electronic device, a third message comprising information indicating whether the authentication is successful, wherein the third message is transmitted from the wireless charger to the electronic device.

13. The method of claim 12, further comprising:

the controller resending the second message or sending another message comprising the authentication information to the electronic device after receiving the third message comprising information indicating that the authentication is failed.

14. The method of claim 12, wherein the authentication information comprises at least one of a security code, a password, full or partial of an identity of the controller, full or partial of an identity of the electronic device, an input to the controller, information indicating that a user of the controller has completed a certain operation on the controller, and a service code denoting a level of service that the wireless charger provides.

15. A method of handling wireless charging authentication for a wireless charger of a wireless charging system, comprising:

the wireless charger making a request to an electronic device of the wireless charging system for an authentication when confirming that the electronic device connects to the wireless charger;

the wireless charger receiving, from the electronic device, a first message comprising authentication information, which is generated by a controller of the wireless charging system in response to reception of a notification from the electronic device;

the wireless charger determining whether the authentication is successful according to the authentication information; and

the wireless charger sending a second message comprising information indicating whether the authentication is successful to the electronic device.

16. The method of claim 15, wherein the step of making the request to the electronic device for the authentication when confirming that the electronic device connects to the wireless charger comprises:

the wireless charger sending, to the electronic device, a request message comprising information indicating that the authentication is required.

17. The method of claim 15, wherein the step of making the request to the electronic device for the authentication when confirming that the electronic device connects to the wireless charger comprises:

the wireless charger receiving, from the electronic device, a third message which requests the wireless charger to adjust a parameter of wireless charging; and

the wireless charger determining whether to adjust the parameter according to whether the authentication is satisfied.

18. The method of claim 15, further comprising:

the wireless charger receiving, from the electronic device, a fourth message which requests a time extension for the authentication.
