Referred to in the present invention connects the short-range wireless communication means).

  On the other hand, the hands-free device 9 is installed in the passenger compartment of the automobile. In the hands-free device 9, the control unit 11 (control means in the present invention) includes a “call start” key for calling, The operation switch 12 (operation means in the present invention) provided with keys such as a “call end” key for ending the call, a “hold” key for holding the call, and the mobile phone 1 are placed on the cradle 13. A position detection unit 14 (position detection unit in the present invention) that detects whether or not the vehicle is placed, a vehicle information recognition unit 15 (vehicle information recognition unit in the present invention) that recognizes vehicle information input from the vehicle, Recognizing voice recognition unit 16 (speech recognition means in the present invention), microphone 17 for inputting transmission voice (sending voice input means on the hands-free device side in the present invention), and speaker 1 for outputting reception voice A Bluetooth communication unit 20 that performs short-range wireless communication conforming to the Bluetooth communication standard with the voice switching unit 19 that connects the (received voice output means on the hands-free device side in the present invention) and the mobile phone 1 described above. The short-range wireless communication means in the present invention is connected.

  In this configuration, as will be described in detail later, the mobile phone 1 has a call process using a handset call (first call process in the present invention) and a call process using hands-free call (second call process in the present invention). ) Can be selected, and any selected call processing can be performed.

  Here, the call process by the handset call is a process in which the mobile phone 1 makes a call through the telephone network 22 with another mobile phone 21 (another phone in the present invention) without using the hands-free device 9. It is. Further, the call processing by the hands-free call is a process in which the mobile phone 1 uses the hands-free device 9 to make a call through the telephone network 22 with another mobile phone 21.

  Next, the operation of the above configuration will be described with reference to FIGS. Here, FIG. 2 is a flowchart showing the process performed by the mobile phone 1 and the process performed by the hands-free device 9. Here, the description will be made on the assumption that the control unit 2 performs the call processing by the handset call in the mobile phone 1.

  In the mobile phone 1, the control unit 2 can perform short-range wireless communication conforming to the Bluetooth communication standard with the hands-free device 9 in a state in which call processing is performed using a handset call. That is, it is monitored whether or not it is within the communication range of Bluetooth (step S1).

  Here, the control unit 2 determines “YES” in step S <b> 1 and outputs a display command to the display 5 if the mobile phone 1 is in a position close to the hands-free device 9 and within the Bluetooth communication range. For example, as shown in FIG. 3, “Can you do hands-free call switching?” To notify that it is possible to make a hands-free call using the hands-free device 9 depending on the communication range of Bluetooth. Is displayed on the display 5 (step S2).

  Then, the control unit 2 monitors whether a switching operation for switching from a handset call to a hands-free call has been performed (step S3), and monitors whether a hands-free switch notification command has been received from the hands-free device 9. (Step S4).

  Here, when the control unit 2 detects that the person using the mobile phone 1 has performed a switching operation for switching from a handset call to a hands-free call (for example, in FIG. 3, that the “1” key has been operated). If it is detected), it is determined as “YES” in step S3, a hands-free call switching command is output to the voice switching unit 8, and the voice path between the telephone communication unit 3 and the Bluetooth communication unit 10 is opened. A free switching notification command is output to the Bluetooth communication unit 10, and a hands-free switching notification command is transmitted from the Bluetooth communication unit 10 to the Bluetooth communication unit 20 of the hands-free device 9 (step S 5), thereby performing a call process using a hands-free call ( Step S6).

  Further, when detecting that the hands-free switching notification command has been received from the hands-free device 9, the control unit 2 determines “YES” in step S4. In this case, the control unit 2 also issues a hands-free call switching command to the voice switching unit 8. And the voice path between the telephone communication unit 3 and the Bluetooth communication unit 10 is opened, and a call process using a hands-free call is performed (step S6).

  Here, the call processing by the hands-free call is a transmission of voices input by the voice input means 6 of the hands-free device 9 from the telephone communication means of the mobile phone 1 to another telephone by short-range wireless communication. In addition, the received voice received by the telephone communication means 3 of the mobile phone 1 from another telephone is output from the received voice output means 18 of the hands-free device 9 by short-range wireless communication.

  On the other hand, in the hands-free device 9, the control unit 11 can perform short-range wireless communication with the mobile phone 1 in conformity with the Bluetooth communication standard when the power is on. That is, it is monitored whether or not it is within the Bluetooth communication range (step T1). Then, if the mobile phone 1 is in a position close to the hands-free device 9 and within the Bluetooth communication range, the control unit 11 determines “YES” in step T1, and sends a hands-free switching notification command from the mobile phone 1. Is received (step T2), and it is monitored whether or not the number of points acquired in response to the occurrence of a trigger, which will be described later, has reached a prescribed number to which a hands-free switching notification command is to be transmitted (step T3). .

  Here, when detecting that the hands-free switching notification command has been received from the mobile phone 1, the control unit 11 determines “YES” in Step T2, and the mobile phone 1 is performing a call process using a hands-free call. Is recognized, and a call process based on a hands-free call is performed (step T4).

  Moreover, the control part 11 acquires a score according to generation | occurrence | production of a trigger according to the method shown below, and compares the acquired score with the regulation score which should transmit a hands-free switching notification command. That is, as shown in FIG. 4, the control unit 11 holds a table that associates triggers with scores, and when any trigger occurs, acquires a score corresponding to the generated trigger. More specifically, the control unit 11 confirms that, for example, a person using the mobile phone 1 gets on and operates a predetermined key for switching from a handset call to a handsfree call at the operation switch 12 of the handsfree device 9. When detected, in this case, since the number of points corresponding to “operation switch operation” is “10”, “10” is acquired.

  Further, when the position detection unit 14 detects that the person using the mobile phone 1 gets on the control unit 11 and places the mobile phone 1 on the cradle 13, for example, the control unit 11 corresponds to a “cradle switch”. Since the score to be obtained is “10” points, “10” points are acquired. In addition, when the vehicle information recognition unit 15 detects that the person using the mobile phone 1 gets on and drives and the vehicle speed exceeds a predetermined speed (for example, 10 kilometers per hour), for example, Since the score corresponding to the “vehicle speed sensor” is “10”, “10” is acquired. In addition, the control unit 11, for example, a person using the mobile phone 1 gets on and utters a specific word (for example, “ha”, “n”, “zu”, “fu”, “li”, “−”). When this is detected by the voice recognition unit 16, in this case, since the score corresponding to “voice recognition” is “10”, “10” is acquired.

  At this time, if the specified number of points to which the hands-free switching notification command is to be transmitted is set to “10”, the control unit 11 triggers according to the occurrence of any of the triggers as described above. It is detected that the number of points acquired in step S3 has reached the prescribed number to which a hands-free switching notification command is to be transmitted, it is determined as “YES” in step T3, a hands-free switching notification command is output to the Bluetooth communication unit 20, and Bluetooth communication is performed. A hands-free switching notification command is transmitted from the unit 20 to the Bluetooth communication unit 10 of the mobile phone 1 (step T5), and a call process using a hands-free call is performed (step T4).

  When the vehicle information recognition unit 15 detects that the person using the mobile phone 1 is seated in the driver's seat, wears the seat belt, and releases the side brake, for example, The score corresponding to the “sensor” is “4”, the score corresponding to the “seat belt sensor” is “4”, and the score corresponding to the “side brake” is “4”. Since “12” points are acquired, even in such a case, it is detected that the number of points acquired by the trigger has reached the prescribed number to which a hands-free switching notification command is to be transmitted, and call processing by hands-free calling is performed. .

  Thereby, the person using the mobile phone 1 switches the call with the person using the other mobile phone 21 from the handset call not using the hands-free device 9 to the hands-free call using the hands-free device 9. be able to.

  As described above, according to the first embodiment, when the mobile phone 1 and another mobile phone 21 make a call through the telephone network 22 by a handset call, the mobile phone 1 and the hands-free device When a predetermined condition is satisfied when short-range wireless communication based on the Bluetooth communication standard is possible with 9, the call can be switched to a hands-free call using the hands-free device 9. did.

  Therefore, when a call between the mobile phone 1 and another mobile phone 21 is made by a handset call, the call between the two can be made by a hands-free call using the hands-free device 9. However, for example, if the person using the mobile phone 1 is outside the passenger compartment, it is possible to avoid switching from the handset call to the hands-free call by not satisfying the predetermined condition. If the person who uses the telephone 1 is in the passenger compartment, it is possible to switch from a handset call to a hands-free call by establishing a predetermined condition, thereby enabling a switch from a handset call to a hands-free call at an appropriate timing. It becomes possible.

  In this case, since the mobile phone 1 is configured so that a switching operation for switching from a handset call to a hands-free call is performed as a predetermined condition, a person using the mobile phone 1 performs the switching operation. Thus, it is possible to switch from a handset call to a hands-free call at an accurate timing. In addition, in the hands-free device 9, a switching operation for switching from a handset call to a hands-free call is performed, the mobile phone 1 is placed on the cradle 13, and the vehicle speed is a predetermined speed (for example, 10 kilometers per hour). Predetermined conditions such that the person who uses the mobile phone 1 utters a specific word (for example, “ha”, “n”, “zu”, “fu”, “li”, “-”) Therefore, even when these triggers are performed, it is possible to switch from a handset call to a hands-free call at an appropriate timing.

Further, in this case, the existing mobile phone 1 and the hands-free device 9 can be easily realized because it is not necessary to change any hardware, and only the software needs to be changed.
(Second Embodiment)
