Abstract

The present invention relates to a method for enabling a wireless communication between at least one peripheral unit (a 1 -aN) and a device ( 100 ), the at least one peripheral unit (a 1 -aN) being arranged for communicating with a pairing system ( 10 ) according to first wireless communication type, the device ( 100 ) being arranged for communicating with the pairing system ( 10 ) according to a second communication type, the method comprising the following steps: —the pairing system ( 10 ) configuring a main communication unit ( 11 ) adapted to communicate according to the first wireless communication type; —pairing the at least one peripheral unit (a 1 -aN) with the main communication unit ( 11 ); —the pairing system ( 10 ) sending to the device ( 100 ) the pairing information suitable for communicating with the at least one peripheral unit (a 1 -aN); —the device ( 100 ) configuring a first communication unit ( 101 ) adapted to communicate with the at least one peripheral unit (a 1 -aN) according to the first wireless communication type, using the pairing information received from the pairing system ( 10 ).

First claim

The invention claimed is:

1. A method for enabling a wireless communication between a device and at least one peripheral unit in a wireless docking environment, comprising:
configuring a main communication circuit arranged in a wireless docking station to communicate with the at least one peripheral unit in accordance with a first wireless communication type;
pairing the wireless docking station with the at least one peripheral unit using pairing information;
determining whether the device is docked to the wireless docking station;
when the device is docked to the wireless docking station, triggering a transfer of the pairing information from the wireless docking station to the device using a second wireless communication type, the pairing information enabling the device to communicate with the at least one peripheral unit directly using the first wireless communication type without going through the wireless docking station.

2. The method of claim 1 , further comprising communicating the pairing information to the device according to a third communication type.

3. The method of claim 2 , further comprising communicating the pairing information to the device according to the third communication type upon connection of the device to the wireless docking station via the second communication type.

4. The method of claim 2 , wherein the third communication type comprises an out-of-band communication type.

5. The method of claim 4 , wherein the third communication type uses a Near Field Communication between the wireless docking station and the device.

6. The method of claim 1 , further comprising taking over control of the first wireless communication type with the at least one peripheral unit when the device stops communicating directly with the at least one peripheral unit.

7. The method of claim 1 , further comprising taking over control of the first wireless communication type with the at least one peripheral unit when the device and the wireless docking station are disconnected.

8. The method of claim 7 , further comprising renewing encryption keys between the main communication circuit and the at least one peripheral unit.

9. The method of claim 8 , wherein the renewing of the encryption keys further comprises determining the minimum communication signal strength value of the first wireless communication type between the main communication circuit and each peripheral unit (a 1 -aN), and communicating by using the determined signal strength value appropriate for each peripheral unit.

10. The method of claim 1 , wherein the first wireless communication type comprises Bluetooth standards.

11. The method of claim 1 , wherein the second communication type comprises Wi-Fi standards or Wi-Fi DIRECT standards.

12. The method of claim 1 , further comprising sending an acknowledgement message to the wireless docking station upon receiving the pairing information.

13. The method of claim 12 , further comprising stopping to communicate with the at least one peripheral unit upon receiving the acknowledgement message.

14. A pairing system for enabling a wireless communication between a device and at least one peripheral unit in a wireless docking environment, comprising:
a memory;
at least one controller coupled to the memory, the controller being configured to:
configure a main communication circuit to communicate with the at least one peripheral unit in accordance with a first wireless communication type;
pair a wireless docking station with the at least one peripheral unit using pairing information;
determine whether the device is docked to the wireless docking station;
when the device is docked to the wireless docking station, trigger a transfer of the pairing information from the wireless docking station to the device in accordance with a second communication type, the pairing information enabling the device to communicate with the at least one peripheral unit directly using the first wireless communication type without going through the wireless docking station.

15. A wireless docking station, comprising:
a memory;
a transceiver;
a controller coupled to the memory, the controller being configured to:
configure a main communication circuit to communicate with the at least one peripheral unit in accordance with a first wireless communication type;
pair a wireless docking station with the at least one peripheral unit using pairing information;
determine whether the device is docked to the wireless docking station;
when the device is docked to the wireless docking station, trigger a transfer of the pairing information from the wireless docking station to the device in accordance with a second communication type, the pairing information enabling the device to communicate with the at least one peripheral unit directly using the first wireless communication type without going through the wireless docking station.
