Abstract

An operating method includes receiving a wireless power signal from a power providing equipment; and transmitting an encoded ID to the power providing equipment, so that the power providing equipment forwards the encoded ID to a server, and the power providing equipment charges a battery of the mobile device by utilizing the wireless power signal according to a charge command provided by the server.

Claims

1. A mobile device comprises:

a battery;

a wireless power receiver configured for receiving a wireless power signal from a power providing, equipment;

a communication transmitter; and

a processor electrically connected with the battery, the wireless power receiver, and the communication transmitter, wherein the processor is configured for;

controlling the communication transmitter to transmit an encoded identifier (ID), which is encoded for privacy and is not able to be decoded by the power providing equipment, to the power providing equipment, so that the power providing equipment forwards the encoded ID to a server, and the power providing equipment charges the battery of the mobile device by utilizing the wireless power signal according to a charge command from the server.

2. The mobile device as claimed in claim 1, wherein the processor is further configured for:

encoding a unique ID to generate the encoded ID.

3. The mobile device as claimed in claim 2, wherein the processor is further configured for:

encoding the unique ID to generate the encoded ID according to a key; and

transmitting the key to the server.

4. The mobile device as claimed in claim 2, wherein the processor is further configured for:

receiving a key from the server; and

encoding the unique ID to generate the encoded ID according to the key.

5. The mobile device as claimed, in claim 1, wherein the processor is further configured for:

receiving the encoded ID from the server.

6. The mobile device as claimed in claim 1, wherein the processor is further configured for:

controlling the communication transmitter to transmit encode information corresponding to the encoded ID to the power providing equipment, wherein the encode information indicates whether a key used to encode a unique ID to generate the encoded ID is received from the server or is generated by the mobile device.

7. The mobile device as claimed, in claim 1, wherein the processor is further configured for:

controlling the communication transmitter to transmit encode information corresponding to the encoded ID to the power providing equipment, wherein the encode information indicates the encoded ID is encoded.

8. A power providing equipment comprises:

a wireless power transmitter configured for transmitting a wireless power signal to a mobile device;

a communication transmitter;

a communication receiver; and

a processor electrically connected with the wireless power transmitter, the communication transmitter, and the communication receiver, wherein the processor is configured for;

receiving, through the communication receiver, an encoded ID from the mobile device, wherein the encoded ID is encoded for privacy and is not able to be decoded by the power providing equipment;

controlling the communication transmitter to transmit the encoded ID to a server, so that the server verifies the encoded ID with a registration database and generates a charge command according to a verification result;

receiving, through the communication receiver, the charge command from the server; and

controlling the wireless power transmitter to transmit the wireless power signal to the mobile device according to the charge command so that a battery of the mobile device is charged by utilizing the wireless power signal.

9. The power providing equipment as claimed in claim 8, Wherein the processor is configured for:

receiving, through the communication receiver, encode information corresponding to the encoded ID from the mobile device, wherein the encode information indicates whether a key used to encode a unique ID to generate the encoded ID is received from the server or is generated by the mobile device.

10. The power providing equipment as claimed in claim 8, wherein the processor is configured for:

receiving, through the communication receiver, encode information corresponding to the encoded ID from the mobile device, wherein the encode information indicates the encoded ID is encoded.

11. The power providing equipment as claimed in claim 8, wherein the processor is configured for:

controlling the wireless power transmitter to stop transmitting, or not to transmit the wireless power signal to the mobile device according to the charge command.

12. The power providing equipment as claimed in claim 8, wherein the processor is configured for:

controlling the communication transmitter to transmit a stop command to the mobile device, so that the mobile device stops charging the battery of the mobile device according to the stop command.

13. The power providing equipment as claimed in claim 8, wherein the processor is configured for:

controlling the wireless power transmitter to supply a first power by utilizing the wireless power signal before receiving the charge command; and

controlling the wireless power transmitter to supply a second power by utilizing the wireless power signal after receiving the charge command,

wherein the second power is greater than the first power.

14. An operating method of a mobile device comprising:

receiving a wireless power signal from a power providing equipment; and

transmitting an encoded ID, which is encoded for privacy and is not able to be decoded by the power providing equipment, to the power providing equipment, so that the power providing equipment forwards the encoded ID to a server, and the power providing equipment charges a battery of the mobile device by utilizing the wireless power signal according to a charge command provided by the server.

15. The operating method as claimed in claim 14 further comprising:

encoding a unique ID to generate the encoded ID.

16. The operating method as claimed in claim 15, wherein the step of encoding the unique ID to generate the encoded ID further comprises:

encoding a unique ID to generate the encoded ID according to a key;

and wherein the operating method further comprises;

transmitting the key to the server.

17. The operating method as claimed in claim 15 further comprising:

receiving a key from the server;

wherein the step of encoding the unique ID to generate the encoded ID further comprises;

encoding a unique ID to generate the encoded ID according to the key.

18. The operating method as claimed in claim 14 further comprising:

receiving the encoded ID from the server.

19. The operating method as claimed in claim 14 further comprising:

transmitting encode information corresponding to the encoded ID to the power providing equipment, wherein the encode information indicates whether a key used to encode a unique ID to generate the encoded ID is received from the server or is generated by the mobile device.

20. The operating method as claimed in claim 14 further comprising:

transmitting encode information corresponding to the encoded ID to the power providing equipment, wherein the encode information indicates the encoded ID is encoded.
