Abstract

Methods and apparatuses are provided for supporting data transmission by a wireless docking center. A first single hop communication link is established with a peripheral device configured to receive content data. A second single hop communication link is established with a dockee device configured to transmit the content data. At least one of a message and the content data is transferred from the second communication link to the first communication link.

Claims

1. A method of supporting data transmission by a wireless docking center, the method comprising the steps of:

establishing a first single hop communication link with a peripheral device configured to receive content data;

establishing a second single hop communication link with a dockee device configured to transmit the content data; and

transferring at least one of a message and the content data from the second communication link to the first communication link.

2. The method of claim 1, before transferring the at least one of the message and the content data, further comprising:

transmitting at least one of an Internet Protocol (IP) address, a Medium Access Control (MAC) address, and a port number of the peripheral device to the dockee device,

wherein the content data includes at least one of the IP address, the MAC address, and the port number of the peripheral device as a destination address.

3. The method of claim 2, wherein the at least one of the IP address, the MAC address, and the port number of the peripheral device is obtained through a discovery procedure of the peripheral device or a capability exchange procedure with the peripheral device.

4. The method of claim 2, wherein the at least one of the IP address, the MAC address, and the port number of the peripheral device is transmitted to the dockee device during a peripheral discovery procedure.

5. The method of claim 2, further comprising:

receiving out of band signaling indicating a direct Real Time Protocol (RTP) connection mode between the dockee device and the peripheral device from the dockee device.

6. The method of claim 5, wherein the out of band signaling is a Universal Plug and Play (UPnP) message.

7. The method of claim 2, wherein the message includes at least one of an IP address, a MAC address, and a port number of the wireless docking center as a destination address.

8. The method of claim 2, further comprising:

forwarding the content data to the peripheral device through an RTP connection.

9. The method of claim 2, wherein the peripheral device is a Miracast sink device supporting a Wi-Fi display.

10. A method of transmitting data by a dockee device configured to transmit content data and dock to a wireless docking center, the method comprising the steps of:

establishing a first single hop communication link with a wireless docking center having established a second single hop communication link with a peripheral device configured to receive the content data; and

transmitting a message or the content data to the wireless docking center through the first communication link.

11. The method of claim 10, before transmitting the message or the content data, further comprising:

receiving at least one of an Internet Protocol (IP) address, a Medium Access Control (MAC) address, and a port number of the peripheral device from the wireless docking center,

wherein the content data includes at least one of the IP address, the MAC address, and the port number of the peripheral device as a destination address.

12. The method of claim 11, wherein the at least one of the IP address, the MAC address, and the port number of the peripheral device is received during a peripheral discovery procedure.

13. The method of claim 11, further comprising:

transmitting out of band signaling indicating a direct Real Time Protocol (RTP) connection mode between the dockee device and the peripheral device to the wireless docking center.

14. The method of claim 13, wherein the out of band signaling is a Universal Plug and Play (UPnP) message.

15. The method of claim 11, wherein the message includes at least one of an IP address, a MAC address, and a port number of the wireless docking center as a destination address.

16. A wireless docking center device supporting data transmission, the wireless docking center device comprising:

a proxy source module configured to establish a first single hop communication link with a peripheral device configured to receive content data;

a proxy sink module configured to establish a second single hop communication link with a dockee device configured to transmit the content data; and

a controller configured to transfer at least one of a message and the content data from the second communication link to the first communication link.

17. The wireless docking center device of claim 16, wherein the controller is further configured to control transmission of at least one of an Internet Protocol (IP) address, a Medium Access Control (MAC) address, and a port number of the peripheral device to the dockee device, and the content data includes at least one of the IP address, the MAC address, and the port number of the peripheral device as a destination address.

18. The wireless docking center device of claim 17, wherein the controller is further configured to obtain at least one of the IP address, the MAC address, and the port number of the peripheral device during a discovery procedure of the peripheral device or a capability exchange procedure with the peripheral device.

19. The wireless docking center device of claim 17, wherein the controller is further configured to control transmission of at least one of the IP address, the MAC address, and the port number of the peripheral device to the dockee device during a peripheral discovery procedure.

20. The wireless docking center device of claim 17, wherein the controller is further configured to control reception of out of band signaling indicating a direct Real Time Protocol (RTP) connection mode between the dockee device and the peripheral device from the dockee device.

21. The wireless docking center device of claim 20, wherein the out of band signaling is a Universal Plug and Play (UPnP) message.

22. The wireless docking center device of claim 17, wherein the message includes at least one of an IP address, a MAC address, and a port number of the wireless docking center as a destination address.

23. The wireless docking center device of claim 17, wherein the controller is further configured to control forwarding of the content data to the peripheral device through an RTP connection.

24. The wireless docking center device of claim 17, wherein the peripheral device is a Miracast sink device supporting a Wi-Fi display.

25. A dockee device configured to transmit content data and dock to a wireless docking center, the dockee device comprising:

a controller configured to establish a first single hop communication link with a wireless docking center having established a second single hop communication link with a peripheral device configured to receive the content data, and

a transceiver configured to transmit a message or the content data to the wireless docking center through the first communication link.

26. The dockee device of claim 25, wherein the controller is further configured to control reception of at least one of an Internet Protocol (IP) address, a Medium Access Control (MAC) address, and a port number of the peripheral device from the wireless docking center, and
