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 basic rate (BR)/enhanced data rate (EDR) by using Bluetooth low energy (LE) in a wireless communication system, the method performed by a first device and comprising:

receiving, from a second device, an advertising message associated with a Bluetooth BR/EDR connection,

wherein the advertising message includes available information of the Bluetooth BR/EDR, location information of detailed information and state information;

transmitting, to the second device, a connection request message for establishing a low energy (LE) connection;

establishing the LE connection with the second device;

transmitting, to the second device, a read request message requesting reading of handover information for connection of the Bluetooth BR/EDR, using the LE connection;

receiving, from the second device, a read response message including the handover information of the second device,

wherein the handover information includes address information, service information indicating supported Bluetooth BR-EDR service and device type information;

activating a BR/EDR of the first device and a BR/EDR of the second device; and

establishing the Bluetooth BR/EDR connection with the second device based on the handover information.

2. The method of claim 1, further comprising:

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

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

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 2, 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, further comprising:

entering a BR/EDR handover standby state for the Bluetooth BR/EDR connection before establishing the Bluetooth BR/EDR connection,

wherein the BR/EDR handover standby state is a state entering directly a BR/EDR connection state without performing a BR/EDR connection procedure.

7. The method of claim 2, further comprising:

transmitting a write request message requesting writing of an operation code instructing the BR/EDR connection based on the handover information; and

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

8. A first device for connecting Bluetooth basic rate (BR)/enhanced data rate (EDR) by using Bluetooth low energy (LE) in a wireless communication system, the first device comprising:

a transceiver; and

a controller functionally connected with the transceiver,

wherein the controller is configured to;

control the transceiver to receive an advertising message associated with a Bluetooth BR/EDR connection from a second device,

wherein the advertising message includes available information of the Bluetooth BR/EDR, location information of detailed information and state information,

control the transceiver to transmit a connection request message for establishing a low energy (LE) connection to the second device,

establish the LE connection with the second device,

control the transceiver to transmit a read request message requesting reading of handover information for connection of the Bluetooth BR/EDR, using the LE connection to the second device,

control the transceiver to receive a read response message including the handover information of the second device from the second device,

wherein the handover information includes address information, service information indicating supported Bluetooth BR-EDR service and device type information,

activate a BR/EDR of the first device and a BR/EDR of the second, and

establish the Bluetooth BR/EDR connection with the second device based on the handover information.

9. The first device of claim 8, wherein the controller is further configured to:

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

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

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.

10. The first device of claim 9, wherein the detailed information includes at least one of frequency information, channel map switching information, transmission power information, or connection state information.

11. The first device of claim 10, 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.
