Abstract

A method of handling authentication for wireless charging which is utilized in a network node comprises transmitting an authentication request to a portable device, after confirming that the portable device connects to a wireless charger; receiving an authentication response for responding the authentication request from the portable device; performing an authentication for the portable device based on the authentication response; and transmitting a message related to a result of the authentication indicating the authentication is successful or not to the wireless charger, after the authentication for the portable device is completed.

Claims

1. A method of handling authentication for wireless charging, the method being utilized in a network node, comprising:

transmitting an authentication request to a portable device, after confirming that the portable device connects to a wireless charger;

receiving an authentication response for responding the authentication request from the portable device;

performing an authentication for the portable device based on the authentication response; and

transmitting a message related to a result of the authentication indicating the authentication is successful or not to the wireless charger, after the authentication for the portable device is completed.

2. The method of claim 1, wherein the message indicates a success of the authentication, when the authentication is successful.

3. The method of claim 1, wherein the message comprises a charging command instructing the wireless charger to charge the portable device, when the authentication is successful.

4. The method of claim 1, wherein the message indicates a failure of the authentication, when the authentication is unsuccessful.

5. The method of claim 1, wherein the message comprises information indicating not to charge the portable device, when the authentication is unsuccessful.

6. The method of claim 1, wherein the message triggers a notification to be displayed in the portable device, to notify that the portable device is not allowed to be charged, when the authentication is unsuccessful.

7. The method of claim 1, further comprising:

receiving timing information transmitted by the wireless charger, wherein the timing information is related to when the wireless charger finishes charging the portable device.

8. The method of claim 1, further comprising:

receiving billing information transmitted by the wireless charger, wherein the billing information is generated according to a time interval during which the wireless charger charges the portable device.

9. The method of claim 1, wherein the network node transmits the authentication request to the portable device via the wireless charger.

10. The method of claim 1, wherein the network node receives the authentication response transmitted by the portable device via the wireless charger.

11. The method of claim 1, wherein the authentication request comprises challenge information, and the authentication response comprises challenge response generated according to the challenge information.

12. The method of claim 11, wherein the challenge information comprises a random challenge and an authentication token, and the challenge response is generated according to the random challenge and the authentication token.

13. A method of handling authentication for wireless charging, the method being utilized in a portable device, comprising:

receiving an authentication request from a network node, after the portable device connects to a wireless charger;

transmitting an authentication response for responding the authentication request to the network node;

receiving a message related to a result of an authentication for the portable device, wherein the authentication for the portable device is performed by the network node; and

displaying a notification in response to the message when the message indicates the authentication is unsuccessful, to notify that the portable device is not allowed to be charged via the wireless charger.

14. The method of claim 13, wherein the message indicates a success of the authentication when the authentication is successful, and the message is received directly from the network node or received via the wireless charger.

15. The method of claim 13, wherein the message indicates a failure of the authentication when the authentication is unsuccessful, and the message is received directly from the network node or received via the wireless charger.

16. The method of claim 13, wherein the portable device receives the authentication request directly from the network node or via the wireless charger.

17. The method of claim 13, wherein the portable device transmits the authentication response directly to the network node or via the wireless charger.

18. A method of handling authentication for wireless charging, the method being utilized in a wireless charger, comprising:

transmitting a first message to a network node to notify that a portable device connects to the wireless charger, after detecting that the portable device connects to the wireless charger;

receiving a second message related to a result of an authentication for the portable device from the network node, wherein the authentication for the portable device is performed by the network node; and

determining whether to wirelessly charge the portable device based on the second message.

19. The method of claim 18, further comprising:

receiving an authentication request from a network node in response to the first message, and transmitting the authentication request to the portable device; and

receiving an authentication response for responding the authentication request from the portable device, and transmitting the authentication response to the network node.

20. The method of claim 18, further comprising:

transmitting a third message to the portable device after determining not to charge the portable device, to notify that the portable device is not allowed to be charged.

21. The method of claim 18, wherein the second message indicates a success of the authentication or comprises a charging command instructing the wireless charger to charge the portable device, when the authentication is successful.

22. The method of claim 18, wherein the second message indicates a failure of the authentication or comprises information indicating not to charge the portable device, when the authentication is unsuccessful.
