    Abstract: A wireless communication system plays multimedia content using Bluetooth communication. The wireless communication system includes receiving a request message related to allowing streaming of second multimedia content of a second source device from the sink device by a first source device streaming first multimedia content; determining whether to allow streaming of the second multimedia content of the second source device; transmitting a response message including a determination result for whether to allow streaming of the second multimedia content to the sink device in response to the request message; transmitting a message for stopping streaming of the second multimedia content to the sink device, when the first source device allows streaming of the second multimedia content; and receiving a streaming stop response message from the sink device responsive to the streaming stop message. The request message includes one of a name, MAC address, and ID of the second source device.
