Abstract

The present invention is directed to a method for pairing a wireless headset and a dongle. The method includes the step of inserting a headset battery into the wireless headset. The headset is configured to retrieve a headset identification key in response to the headset battery insertion. A dongle battery is inserted into a dongle within a predetermined period of time after inserting the headset battery into the wireless headset. The dongle is configured to retrieve a dongle identification key in response to the dongle battery being inserted. Handshaking transmissions are exchanged between the wireless headset and the dongle, wherein the headset random identification key is combined with the dongle random identification key to form a system verification key, the system verification key being employed by the wireless headset and the dongle to code and decode transmissions between the wireless headset and the dongle.

Claims

1. A method for pairing a wireless headset and a dongle, the method comprising:

inserting a headset battery into the wireless headset, the headset being configured to retrieve a headset identification key in response thereto;

inserting a dongle battery into a dongle within a predetermined period of time after inserting the headset battery into the wireless headset, the dongle being configured to retrieve a dongle identification key in response thereto; and

exchanging handshaking transmissions between the wireless headset and the dongle, wherein the headset identification key is combined with the dongle identification key to form a system verification key, the system verification key being employed by the wireless headset and the dongle to code and decode transmissions between the wireless headset and the dongle.

2. The method of claim 1, wherein the wireless headset device is configured to enter a low RF power mode during the predetermined period of time.

3. The method of claim 2, wherein the dongle must be disposed within a predetermined first radius relative to the wireless headset device during the predetermined period of time.

4. The method of claim 2, wherein the wireless headset device is configured to enter a normal RF power mode after the predetermined period of time.

5. The method of claim 4, wherein an effective transmission range between the dongle and the wireless headset in the normal RF power mode is approximately fifty (50) feet.

6. The method of claim 1, further comprising the step of inserting the dongle into a wireless communications device, wireless communications being established between the wireless headset and the wireless communications device via the dongle.

7. The method of claim 1, wherein the wireless headset is configured to enter a sleep mode after the wireless communications are established between the wireless headset and the wireless communications device if there is no wireless communication activity between the wireless headset and the wireless communications device after a second predetermined period of time.

8. The method of claim 7, wherein the wireless headset is configured to attempt to reestablish communications with the dongle after it awakes from sleep mode, the wireless headset being configured to automatically awake from sleep mode in response to user wireless communications activity.

9. The method of claim 7, wherein the wireless communications device is selected from a group comprising a wireless telephone, a cordless telephone, and/or a walkie-talkie.

10. The method of claim 1, wherein the step of exchanging further comprises:

at least one initial RF transmission from the wireless headset to a previously paired dongle;

at least one second interrogation transmission from the wireless headset after a third predetermined period of time has elapsed after the at least one initial transmission without a response from the previously paired dongle, the at least one second interrogation transmission being configured to initiate handshaking with the dongle;

transmitting the dongle identification key from the dongle to the wireless headset in response to the at least one second interrogation transmission; and

transmitting the headset identification key from the wireless headset to the dongle in response thereto.

11. The method of claim 10, wherein the wireless headset and the dongle independently derive the system verification key in accordance with a predetermined algorithm.

12. The method of claim 1, wherein the dongle identification key includes a dongle random identification key and wherein the headset identification key includes a headset random identification key.

13. The method of claim 1, wherein the dongle identification key includes a dongle pre-programmed identification key and wherein the headset identification key includes a headset pre-programmed identification key.

14. A wireless headset system comprising:

a dongle comprising a connector configured to couple to a wireless communications device, the dongle also including at least one dongle circuit, a dongle transceiver portion, and a dongle power supply including a dongle battery receptacle unit, the at least one circuit being configured to retrieve a dongle identification key in response to a dongle battery being inserted into the dongle battery receptacle unit; and

a wireless headset comprising at least one headset circuit, a headset transceiver portion, and a headset power supply including a headset battery receptacle unit, the at least one headset circuit being configured to,

retrieve a headset identification key in response to a headset battery being inserted into the headset battery receptacle unit,

initiate handshaking transmissions with the dongle if the dongle battery is inserted into the battery receptacle unit within a predetermined period of time, whereby the headset random identification key is combined with the dongle random identification key to form a system verification key, the system verification key being employed by the wireless headset and the dongle to code and decode transmissions between the wireless headset and the dongle.

15. The system of claim 14, wherein the at least one headset circuit is selected from a group that includes a microprocessor, an FPGA, and/or an ASIC.

16. The system of claim 14, wherein the at least one headset circuit is configured to drive the wireless headset into a low RF power mode during the predetermined period of time.

17. The system of claim 14, wherein the at least one headset circuit is configured to drive the wireless headset into a normal RF power mode after the predetermined period of time.

18. The system of claim 17, wherein an effective transmission range between the dongle and the wireless headset in the normal RF power mode is approximately fifty (50) feet.

19. The system of claim 14, further comprising the step of inserting the dongle connector into the wireless communications device, wireless communications being established between the wireless headset and the wireless communications device via the dongle, and wherein the wireless communications device is selected from a group comprising a wireless telephone, a cordless telephone, and/or a walkie-talkie.

20. The system of claim 14, wherein the at least one headset circuit is configured to drive the wireless headset into a sleep mode if there is no wireless communication activity between the wireless headset and the wireless communications device after a second predetermined period of time.

21. The system of claim 20, wherein the wireless headset is configured to attempt to reestablish communications with the dongle after it awakes from sleep mode, the wireless headset being configured to automatically awake from sleep mode in response to user activity.

22. The system of claim 14, wherein the at least one headset circuit is further configured to:

transmit at least one initial RF transmission to a previously paired dongle;

transmit at least one second interrogation transmission after a third predetermined period of time has elapsed after the at least one initial transmission without a response from the previously paired dongle, the at least one second interrogation transmission being configured to initiate handshaking with an unknown dongle; and

transmitting the headset random identification key from the wireless headset to the dongle in response to receiving an unknown dongle random identification key from the unknown dongle in response to the at least one second interrogation transmission.

23. The system of claim 14, wherein the dongle identification key includes a dongle random identification key and wherein the headset identification key includes a headset random identification key.
