Abstract

The present invention relates to a method and an apparatus for connecting Bluetooth BR/EDR by using Bluetooth low energy (LE) technology. According to the present invention, provided are a method including: receiving an advertising message from a second device; transmitting a request message for requesting detailed information associated with the Bluetooth BR/EDR connection to the second device based on the advertising message; receiving a response message including the detailed information from the second device in response to the request message; transmitting a connection request message to the second device based on the detailed information; and establishing the Bluetooth BR/EDR LE connection with the second device, wherein the advertising message includes at least one of location information of the detailed information or available information of the Bluetooth BR/EDR.

Claims

1. A method for connecting Bluetooth BR/EDR by using Bluetooth low energy (LE) in a wireless communication system, a method performed by a first device, comprising:

receiving an advertising message from a second device;

transmitting a request message for requesting detailed information associated with the Bluetooth BR/EDR connection to the second device based on the advertising message;

receiving a response message including the detailed information from the second device in response to the request message;

transmitting a connection request message to the second device based on the detailed information; and

establishing the Bluetooth BR/EDR LE connection with the second device,

wherein the advertising message includes at least one of location information of the detailed information or available information of the Bluetooth BR/EDR.

2. The method of claim 1, wherein the location information indicates one of a scan response message, a Generic Attribute Profile (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 frequency information, channel map switching information, transmission power information, or connection state information.

4. The method of claim 3, wherein when the channel map switching information has a value of ‘

True’

, a Bluetooth BR/EDR channel map is generated based on a channel map of the Bluetooth LE.

5. The method of claim 4, further comprising

generating the Bluetooth BR/EDR channel map through a channel estimation algorithm.

6. The method of claim 1, wherein the connection request message includes at least one of device type information, service type information, or service providing distance information.

7. A method for establishing a connection of an alternative communication means through Bluetooth BR/EDR in a wireless communication system, a method performed by a first device, comprising:

transmitting an ID packet to a second device;

receiving a response message including first information associated with an alternative interface from the second device in response to the ID packet;

establishing a Bluetooth BR/EDR LE connection with the second device;

transmitting a handover request message through the established Bluetooth BR/EDR connection;

receiving a handover response message as the response to the hand over request message; and

establishing an alternative interface link with the second device,

wherein the first information associated with the alternative interface includes at least one of a device type, a service type, or a service providing range, and

wherein at least one of the handover request message or the handover response message includes second information associated with connection of the alternative interface.

8. The method of claim 7, wherein the second information includes at least one of frequency information, channel map switching information, transmission power information, or connection state information.

9. The method of claim 8, wherein when the channel map switching information has a value of ‘

True’

, a channel map of the alternative interface is generated based on the channel map of Bluetooth LE.

10. The method of claim 9, further comprising:

generating the Bluetooth BR/EDR channel map through a channel estimation algorithm.

11. A first device in a method for connecting Bluetooth BR/EDR by using 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 control unit performs a control to,

receive an advertising message from a second device,

transmit a request message for requesting detailed information associated with the Bluetooth BR/EDR connection to the second device based on the advertising message,

receive a response message including the detailed information from the second device in response to the request message,

transmit a connection request message to the second device based on the detailed information, and

establish the Bluetooth BR/EDR LE connection with the second device,

wherein the advertising message includes at least one of location information of the detailed information or available information of the Bluetooth BR/EDR.

12. The first device of claim 11, wherein the location information indicates one of a scan response message, a Generic Attribute Profile (GATT) data base, or a scan response message and the GATT data base.

13. The first device of claim 11, wherein the detailed information includes at least one of frequency information, channel map switching information, transmission power information, or connection state information.

14. The first device of claim 13, wherein when the channel map switching information has a value of ‘

True’

, a Bluetooth BR/EDR channel map is generated based on a channel map of the Bluetooth LE.

15. A first device in a method for establishing a connection of an alternative communication means through Bluetooth BR/EDR 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 control unit performs a control to,

transmit an ID packet to a second device,

receive a response message including first information associated with an alternative interface from the second device in response to the ID packet,

establish a Bluetooth BR/EDR LE connection with the second device,

transmit a handover request message through the established Bluetooth BR/EDR connection,

receive a handover response message in response to the handover request message, and

establish an alternative interface link with the second device,

wherein the first information associated with the alternative interface includes at least one of a device type, a service type, or a service providing range, and

wherein at least one of the handover request message or the handover response message includes second information associated with connection of the alternative interface.
