Method and device for connecting device in short-range wireless communication system

A first device in a short range wireless communication system, the first device comprising:

• a transceiver;
• and
• a controller configured to:
• control the transceiver to transmit a discovery signal including a connection information request to a second device,
• control the transceiver to receive a discovery response signal including information on a third device connected to the second device from the second device,
• control the transceiver to transmit a connection request signal to the second device based on the information on the third device, in case that the third device is selected as a connection target of the first device,
• control the transceiver to receive a connection response signal determined based on the connection request signal from the second device, and
• control to establish a connection to the third device based on the connection response signal,
• wherein the connection between the third device and the second device is released based on the connection request signal transmitted by the first device.

A communication method of a second device connected to a third device and communicating with a first device in a short range wireless communication system, the method comprising:

• receiving a discovery signal including a connection information request from the first device;
• and
• transmitting, to the first device, a discovery response signal including information on the third device determined based on the discovery signal;
• receiving, from the first device, a connection request signal based on the information on the third device;
• transmitting, to the first device, a connection response signal determined based on the connection request signal;
• and
• releasing a connection between the third device and the second device based on the connection request signal transmitted by the first device,
• wherein the connection between the third device and the first device is established based on the connection response signal.

A second device connected to a third device and communicating with a first device in a short range wireless communication system, the second device comprising:

• a transceiver;
• and
• a controller configured to control to:
• control to the transceiver to receive a discovery signal including a connection information request from the first device,
• control to the transceiver to transmit, to the first device, a discovery response signal including information on the third device determined based on the discovery signal,
• control to the transceiver to receive, from the first device, a connection request signal based on the information on the third device,
• control to the transceiver to transmit, to the first device, a connection response signal determined based on the connection request signal, and
• release a connection between the third device and the second device based on the connection request signal transmitted by the first device,
• wherein a connection between the third device and the first device is established based on the connection response signal.
