Abstract

Embodiments disclosed describe room specific pairing of electronic devices using the combination of ultrasonic signal and other wireless means such as Bluetooth. The ultrasonic signal is used to communicate a unique identifier to the electronic devices within the same physical location. The electronic device receiving the ultrasonic signal uses the unique identifier to establish a secure wireless communication with the base station. The wireless communication is then used to communication the configuration information for a second network connection between the base station and the electronic device.

Claims

1. A method of establishing a network connection, the method comprising the steps of:

detecting an ultrasonic signal provided by a base station with an electronic device;

decoding a unique identifier partially identifying the base station from the ultrasonic signal;

combining the unique identifier with a predetermined term to determine a complete identity of the base station;

performing a search for a base station having the complete identity;

pairing with the base station identified in the search; and

establishing a first network connection between the electronic device and the base station identified in the search after completing pairing.

2. The method of claim 1, wherein the step of performing a search is done by determining names provided by base stations within a wireless network range of the electronic device.

3. The method of claim 2, wherein the wireless network is a Bluetooth personal area network (PAN), wherein the pairing has developed a Bluetooth link between the base station and the electronic device, and wherein the names are friendly names of the base stations in the Bluetooth PAN.

4. The method of claim 3, further comprising:

receiving a first network connection address of the base station over the Bluetooth PAN, the first network connection address used in the step of establishing a first network connection.

5. The method of claim 2, wherein the wireless network is a WiFi network, wherein the base stations are also WiFi access points and the names are SSIDs of the WiFi access points.

6. The method of claim 1, wherein the step of performing a search is done by providing a query for a first network connection address based on the complete identity, and wherein the step of pairing with the base station is done by contacting the base station at a returned first network connection address.

7. The method of claim 1, wherein the base station is a video conferencing unit.

8. An electronic device, comprising:

an ultrasonic subsystem to receive ultrasonic signals;

one or more interfaces for communicatively connecting to a base station;

a processing unit communicatively connected to the ultrasonic subsystem and the one or more interfaces, the processing unit configured to;

detect the ultrasonic signal provided by the base station;

decode a unique identifier partially identifying the base station from the ultrasonic signal;

combine the unique identifier with a predetermined term to determine a complete identity of the base station;

perform a search for a base station having the complete identity;

pair with the base station identified in the search; and

establish a first network connection between the electronic device and the base station identified in the search after completing pairing.

9. The electronic device of claim 8, wherein performing a search by the processing unit includes determining names provided by base stations within a wireless network range of the electronic device.

10. The electronic device of claim 9, wherein the wireless network is a Bluetooth personal area network (PAN), wherein the pairing has developed a Bluetooth link between the base station and the electronic device, and wherein the names are friendly names of the base stations in the Bluetooth PAN.

11. The electronic device of claim 10, wherein the processing unit is further configured to:

receive a first network connection address of the base station over the Bluetooth PAN, the first network connection address used in establishing a first network connection.

12. The electronic device of claim 9, wherein the wireless network is a WiFi network, wherein the base stations are also WiFi access points and the names are SSIDs of access points.

13. The electronic device of claim 8, wherein performing a search by the processing unit includes performing a search by providing a query for a first network connection address based on the complete identity, and wherein pairing with the base station is done by contacting the base station at a returned first network connection address.

14. The electronic device of claim 8, wherein the base station is a video conferencing unit.

15. A method of establishing a network connection, the method comprising the steps of:

combining a unique identifier with a predetermined term to create a name for a first base station, wherein the unique identifier distinguishes the first base station from other base stations;

advertising the unique identifier by an ultrasonic signal to an electronic device;

receiving a pairing request from the electronic device based on the unique identifier;

pairing with the electronic device originating the pairing request; and

establishing a first network connection between the electronic device and the base station after completing pairing.

16. The method of claim 15, wherein the step of receiving a pairing request is done through a Bluetooth personal area network (PAN), and wherein the pairing has developed a Bluetooth link between the base station and the electronic device.

17. The method of claim 16, further comprising the step of:

sending a first network connection address of the base station over the Bluetooth PAN, the first network connection address used in the step of establishing a first network connection.

18. The method of claim 15, wherein the step of receiving a pairing request is done through a WiFi network and the base stations are also WiFi access points.

19. The method of claim 15, wherein the base station is a video conferencing unit.

20. A base station device, comprising:

a memory;

an ultrasonic subsystem for generating an ultrasonic signal;

one or more interfaces for communicatively connecting to an electronic device;

a processing unit communicatively connected to the ultrasonic subsystem, the memory, and the one or more interfaces, the processing unit configured to;

advertise the unique identifier by an ultrasonic signal to an electronic device;

receive a pairing request from the electronic device based on the unique identifier;

pair with the electronic device originating the pairing request; and

establish a first network connection between the electronic device and the base station after completing pairing.

21. The base station of claim 20, wherein receiving a pairing request is through a Bluetooth personal area network (PAN), and wherein the pairing has developed a Bluetooth link between the base station and the electronic device.

22. The base station of claim 21, wherein the processing unit is further configured to:

send a first network connection address of the base station over the Bluetooth PAN, the first network connection address used in the step of establishing a first network connection.

23. The base station of claim 20, wherein receiving a pairing request is through a WiFi network and the base stations are also WiFi access points.

24. The base station of claim 20, wherein the base station is a video conferencing unit.
