<p><P>PROBLEM TO BE SOLVED: To provide a control method with which a communication system can transfer to an audio communication during a data communication, the communication system including a base station of a mobile communication system, a mobile station and a terminal device connected with the mobile station via Bluetooth(R) communication. <P>SOLUTION: When a voice incoming call S11 is generated during a data communication S10, a mobile station 2 (server) transmits a data service cutoff request S12 to a terminal device 3 (client) in order to notify a temporary stop of the data communication S10 with the terminal device 3. In an original Bluetooth(R) standard procedure, the data service cutoff request S12 is defined as a procedure to be transmitted from the client to the server not in the middle of the data communication but after the completion of the data communication. When the data service cutoff request S12 is received, the terminal device 3 recognizes that it is not the original Bluetooth(R) standard procedure, and determines there is a voice call interruption (S14). <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
