Abstract

A method of identifying a wireless power receiver for a mobile device in a wireless power system includes transmitting a first identity of the mobile device to a wireless power base station of the wireless power system via a first wireless communication interface, receiving a first message including the first identity from the wireless power base station via a second wireless communication interface, and identifying the first message is destined to the mobile device according to the first identity.

Claims

1. A method of identifying a wireless power receiver for a mobile device in a wireless power system, comprising:

transmitting a first identity of the mobile device to a wireless power base station of the wireless power system via a first wireless communication interface;

receiving a first message including the first identity from the wireless power base station via a second wireless communication interface after the first identity is transmitted via the first wireless communication interface; and

identifying the first message is destined for the mobile device according to the first identity included in the first message;

wherein the first wireless communication interface is In-Band and uni-directional wireless communication interface, and the second wireless communication interface is Out-of-Band and bi-directional wireless communication interface.

2. The method of claim 1, further comprising:

transmitting a second message including the first identity to the wireless power base station in response to the first message via the second wireless communication interface.

3. The method of claim 1, further comprising:

receiving a third message including a second identity from the wireless power base station via the second wireless communication interface; and

identifying the third message is not destined for the mobile device according to the second identity included in the third message.

4. The method of claim 1, wherein the first wireless communication interface is realized by a modulation of wireless power signals of the wireless power base station, and the modulation is Frequency-Shift Keying modulation or Load modulation.

5. The method of claim 1, wherein the second wireless communication interface is realized by Bluetooth Low Energy, Near Field Communication, Zigbee, Wifi-Direct communication, Device-to-Device communication or Machine-to-Machine communication defined by third generation partnership project.

6. The method of claim 1, wherein the first identity is an identity of the wireless power receiver of the mobile device.

7. A method of identifying a wireless power receiver for a wireless power base station in a wireless power system, comprising:

receiving a first identity from a mobile device of the wireless power system via a first wireless communication interface; and

transmitting a first message including the first identity to the mobile device via a second wireless communication interface after the first identity is received via the first wireless communication interface, such that the mobile device is able to identify that the first message is destined for the mobile device according to the first identity included in the first message;

wherein the first wireless communication interface is In-Band and uni-directional wireless communication interface, and the second wireless communication interface is Out-of-Band and bi-directional wireless communication interface.

8. The method of claim 7, further comprising:

receiving a second message including the first identity from the mobile device in response to the first message via the second wireless communication interface.

9. The method of claim 7, wherein the first wireless communication interface is realized by a modulation of wireless power signals of the wireless power base station, and the modulation is Frequency-Shift Keying modulation or Load modulation.

10. The method of claim 7, wherein the second wireless communication interface is realized by Bluetooth Low Energy, Near Field Communication, Zigbee, Wifi-Direct communication, Device-to-Device communication or Machine-to-Machine communication defined by third generation partnership project.

11. The method of claim 7, wherein the first identity is an identity of the wireless power receiver of the mobile device.
