ABSTRACT:
A scheme for realizing AV data transfer processing utilizing the transport layer protocol such as RTP protocol, between radio terminals in a radio system for carrying out data transfer after establishing a logical connection between radio terminals prior to data transfer between radio terminals such as Bluetooth is disclosed. In the case of transferring data packets containing an AV stream and exchanging control packets containing control information regarding transfer of the data packets, different logical channels are assigned to the data packets and the control packet so that the data packets and the control packet are transferred by these different logical channels.
