Abstract

The present invention relates to a method and an apparatus for establishing a Wi-Fi Direct connection through Bluetooth low energy (LE) technology. According to the present invention, provided are a method including: receiving an advertising message including information associated with Wi-Fi Direct from a second device; transmitting a request message for requesting detailed information of the Wi-Fi Direct to the second device based on the advertising message; receiving a response message including the detailed information in response to the request message; and establishing the Wi-Fi Direct connection with the second device, wherein the advertising message is transmitted through a specific channel for a Bluetooth low energy (LE) connection and the information includes at least one of ID information indicating the Wi-Fi Direct, location information of the detailed information, or available information of an alternative communication means, and an apparatus thereof

Claims

1. A method for establishing a Wi-Fi Direct connection through Bluetooth low energy (LE) in a wireless communication system, a method performed by a first device, comprising:

receiving an advertising message including information associated with Wi-Fi Direct from a second device;

transmitting a request message for requesting detailed information of the Wi-Fi Direct to the second device based on the advertising message;

receiving a response message including the detailed information in response to the request message; and

establishing the Wi-Fi Direct connection with the second device,

wherein the advertising message is transmitted through a specific channel for a Bluetooth low energy (LE) connection, and

the information includes at least one of ID information indicating the Wi-Fi Direct, location information of the detailed information, or available information of an alternative communication means.

2. The method of claim 1, wherein the location information indicates one of a scan response message, a GATT data base, or a scan response message and the GATT data base.

3. The method of claim 1, wherein the detailed information includes at least one of channel information for the Wi-Fi Direct connection, MAC address information of the second device, network type information, or channel type information.

4. The method of claim 1, wherein the request message and the response message are transmitted/received through the specific channel.

5. The method of claim 1, further comprising:

transmitting a Bluetooth low energy (LE) connection request message to the second device;

receiving a Bluetooth low energy (LE) connection response message from the second device in response to the Bluetooth low energy (LE) connection request message; and

establishing a Bluetooth low energy (LE) connection with the second device,

wherein the request message and the response message are transmitted/received through a data channel for transmitting/receiving data of Bluetooth low energy (LE).

6. The method of claim 1, further comprising:

transmitting a connection request message for the Wi-Fi Direct connection to the second device; and

receiving a response message in response to the connection request message.

7. The method of claim 6,

wherein the connection request message includes a command for the Wi-Fi Direct connection, and

wherein the response message includes result information for the command and reason information for a failure when the result information indicates the failure.

8. The method of claim 1,

wherein the information further includes service information supported by the Wi-Fi Direct, and

wherein the ID information, the location information, the available information, and the service information are included in a bit format.

9. A first device in a method for establishing a Wi-Fi Direct connection through Bluetooth low energy (LE) in a wireless communication system, the first device comprising:

a communication unit for transceiving a signal with the outside by a wired and/or wireless scheme; and

a control unit functionally connected with the communication unit,

wherein the controller performs a control to

receive an advertising message including information associated with Wi-Fi Direct from a second device,

transmit a request message for requesting detailed information of the Wi-Fi Direct to the second device based on the advertising message,

receive a response message including the detailed information in response to the request message, and

establish the Wi-Fi Direct connection with the second device,

wherein the advertising message is transmitted through a specific channel for a Bluetooth low energy (LE) connection, and

wherein the information includes at least one of ID information indicating the Wi-Fi Direct, location information of the detailed information, or available information of an alternative communication means.

10. The first device of claim 9, wherein the location information indicates one of a scan response message, a GATT data base, or a scan response message and the GATT data base.

11. The first device of claim 9, wherein the detailed information includes at least one of channel information for the Wi-Fi Direct connection, MAC address information of the second device, network type information, or channel type information.

12. The first device of claim 9, wherein the request message and the response message are transmitted/received through the specific channel.

13. The first device of claim 9, wherein the controller performs a control to,

transmit a Bluetooth low energy (LE) connection request message to the second device,

receive a Bluetooth low energy (LE) connection response message from the second device in response to the Bluetooth low energy (LE) connection request message, and

establish a Bluetooth low energy (LE) connection with the second device,

wherein the request message and the response message are transmitted/received through a data channel for transmitting/receiving data of Bluetooth low energy (LE).

14. The first device of claim 9, wherein the controller performs a control to,

transmit a connection request message to the second device, and

receive a response message in response to the connection request message.

15. The first device of claim 14,

wherein the connection request message includes a command for the Wi-Fi Direct connection, and

wherein the response message includes result information for the command and reason information for a failure when the result information indicates the failure.

16. The first device of claim 9, wherein the information further includes service information supported by the Wi-Fi Direct, and

wherein the ID information, the location information, the available information, and the service information are included in a bit format.
