Abstract

An apparatus to relay connection requests between wireless devices in a wireless network including at least one piconet having a master device and one or more slave devices, the apparatus including a connection request relay unit in the master device to relay to a first wireless device a request from a second wireless device to connect to the first wireless device, wherein the first wireless device is one of the oner or more slave devices, and the second wireless device is outside the at least one piconet having the master device, and a method of relaying the connection requests.

Claims

1. A method of relaying connection requests between wireless devices in a wireless network including at least one piconet having a master device and one or more slave devices, the method comprising:

determining whether a second wireless device exists in the one or more slave devices connected to a master device in response to the master device receiving a connection relay request for the second wireless device from a first wireless device, wherein the determining is done by the master device; and

relaying the connection request to the second wireless device so that the second wireless device attempts to connect to the first wireless device in response to the second wireless device existing.

2. The method of claim 1, wherein the first wireless device is a wireless device in a different piconet than the piconet in which the second wireless device is included at the time the master device receives the connection relay request.

3. The method of claim 1, wherein the master device determines the existence of the second wireless device by referring to a connected device list.

4. The method of claim 1, wherein the first wireless device, the second wireless device, and the master device are BLUETOOTH®

capable devices.

5. A method of relaying connection requests between wireless devices in a wireless network which communicates through an access point operating as a master device, the method comprising:

determining whether a second wireless device exists in one or more slave devices connected to the access point in response to the access point receiving a connection relay request for the second wireless device from a first wireless device, wherein the determining is done by the access point; and

relaying the connection request to the second wireless device by the access point in response to the second wireless device existing, so that the second wireless device, as a master device of the first wireless device, attempts to connect to the first wireless device.

6. An apparatus to relay connection requests between wireless devices in a wireless network including at least one piconet having a master device and at least one slave device, the apparatus comprising:

a connected device list module included in the master device to manage, in a connected device list, a list of devices connected to the master device;

a connection request relay module included in the master device to search the connected device list module in response to a connection relay request for a second wireless device being received from a first wireless device, and to order a relay of a connection request in response to the second wireless device existing in the connected device list; and

a connection manager included in the master device to relay the connection request to the second wireless device so that the second wireless device attempts to connect to the first wireless device in response to a relay order of the connection request being received from the connection request relay module.

7. The apparatus of claim 6, wherein the connection manager updates the connected device list module in response to a device being newly connected or disconnected with the master device.

8. The apparatus of claim 6, wherein the first wireless device is a wireless device in a different piconet than the piconet in which the second wireless device is included at the time the connection relay request is received.

9. The apparatus of claim 6, wherein the first wireless device, the second wireless device, and the master device are BLUETOOTH®

capable devices.

10. The apparatus of claim 6, wherein the connection manager relays the connection request so that the second wireless device, as a master device of the first wireless device, attempts to connect to the first wireless device.

11. The apparatus of claim 6, wherein the connection manager relays the connection request through a BLUETOOTH®

stack in the master device.

12. A method of relaying connection requests between wireless devices in a wireless network including at least one piconet having a master device and one or more slave devices, the method comprising:

receiving in the master device a request from a first wireless device to connect to a second wireless device, wherein the first wireless device is outside the at least one piconet having the master device;

determining in the master device whether the second wireless device exists in the one or more slave devices; and

relaying by the master device the request to the second wireless device in response to the second wireless device existing in the one or more slave devices.

13. The method of claim 12, further comprising attempting to connect, by the second wireless device, to the first device in response to the second wireless device receiving the request.

14. The method of claim 12, wherein the master device and the first and second wireless devices are BLUETOOTH®

capable devices.

15. An apparatus to relay connection requests between wireless devices in a wireless network including at least one piconet having a master device and one or more slave devices, the apparatus comprising:

a connection request relay unit in the master device to relay to a first wireless device a request from a second wireless device to connect to the first wireless device;

wherein the first wireless device is one of the one or more slave devices, and the second wireless device is outside the at least one piconet having the master device.

16. The apparatus of claim 15, further comprising a connected device list unit in the master device to manage, in a connected device list, a list of devices connected to the master device.

17. The apparatus of claim 16, wherein connection request relay unit determines whether the first wireless device is one of the one or more slave devices by searching the connected device list.

18. The apparatus of claim 17, wherein the connection request relay unit relays the request from the second wireless device to the first wireless device in response to the first wireless device being identified in the connected device list.

19. The apparatus of claim 15, wherein the request is received by and transmitted from the master device through a BLUETOOTH®

stack.

20. The apparatus of claim 15, wherein the first wireless device attempts to connect to the second wireless device in response to receiving the request from the master device.

21. The apparatus of claim 15, wherein the second wireless device is another master device of a piconet other than the at least one piconet.

22. A method of relaying connection requests between wireless devices in a wireless network including at least one piconet having a master device and one or more slave devices, the method comprising:

receiving, in the master device, a request from a first wireless device to connect to a second wireless device; and

relaying the request to the second wireless device in response to the second wireless device being one of the one or more slave devices;

wherein the first wireless device is outside the at least one piconet having the master device.

23. The method of claim 22, further comprising attempting to connect, by the second wireless device, to the first wireless device in response to receiving the request.

24. A method of relaying connection requests between wireless devices in a wireless network, the method comprising:

sending a connection request from a service client device to a service provision device by relaying the connection request from the service client device through a master device of the service provision device;

wherein the service provision device is supporting an ad hoc wireless network based on BLUETOOTH® and

is set to a slave status.
