Abstract

Apparatus, methods, and systems are disclosed for pairing a first wireless device with a second wireless device and establishing an identifier. The first wireless device transmits to the second wireless device from the first wireless device with the identifier. The first wireless device shares the identifier with a third wireless device. This allows the third device to transmit to the second wireless device appearing as the first wireless device. The first wireless device stops transmitting while the third wireless device transmits. Since the third wireless device used the identifier for the first wireless device, the second wireless device believes is communicating with the first wireless device.

Claims (33)

1. An apparatus comprising:

a first device having a transmitter, and an identifier, the first device configured to pair with a second device using the identifier;

the first device configured to communicate with a third device having a transmitter, the third device configured to receive the identifier from the first device, wherein the third device transmits to the second device using the identifier; and

wherein, the third device is configured to request the identifier from the first device, use the identifier to communicate with the second device, and to return the identifier to the first device at or around the time the third device is done communicating with the second device.

2. The apparatus of claim 1 , wherein the identifier includes a link key.

3. The apparatus of claim 1 , wherein the first device transmitter is off when the third transmitter transmits.

4. The apparatus of claim 3 , wherein the third device transmitter is off when the first transmitter transmits.

5. The apparatus of claim 1 , wherein the first device is a personal computer.

6. The apparatus of claim 5 , wherein the third device is a phone.

7. The apparatus of claim 5 , wherein the third device is a cellular device.

8. The apparatus of claim 1 wherein the first device is a video game console.

9. The apparatus of claim 8 , wherein the third device is a cellular device.

10. The apparatus of claim 1 , further comprising a fourth device having a transmitter, the fourth device configured to receive the identifier from the first device, wherein the fourth device transmits using the identifier.

11. The apparatus of claim 1 , wherein the transmitter is a Bluetooth transmitter.

12. The apparatus of claim 1 , wherein the transmitter is a Wi-Fi transmitter.

13. The apparatus of claim 1 , wherein the third wireless device is a personal computer and the first wireless device is a mini-computer coupled to the personal computer.

14. The apparatus of claim 13 , wherein the second device is one of a personal digital assistant, a smart phone, a personal computer, or a cellular phone.

15. A system comprising:

a first device;

a second device, the first device configured to pair with the second device, the first device having an identifier, the first device configured to transmit the identifier to the second device;

a third device, the third device coupled to the first device, the third device configured to receive the identifier from the first device, and the third device configured to transmit the identifier to the second wireless device; and

wherein, the third device is configured to request the identifier from the first device, use the identifier to communicate with the second device, and to return the identifier to the first device at or around the time the third device is done communicating with the second device.

16. The system of claim 15 , wherein the first device is a personal computer, and the second device is a headset.

17. The apparatus of claim 15 , wherein the first device transmits with a Bluetooth transmitter.

18. A method comprising:

pairing a first wireless device with a second wireless device;

establishing an identifier;

transmitting to the second wireless device from the first wireless device, wherein the transmitting includes using the identifier;

requesting the identifier from the first wireless device;

transmitting to the second wireless device from the third wireless device, wherein the transmitting includes using the identifier; and

returning the identifier to the first wireless device at or around the time the third device is done transmitting to the second device.

19. The method of claim 18 , wherein when the first device is transmitting the third device cannot transmit.

20. The method of claim 19 , wherein when the third device is transmitting the first device cannot transmit.
