  The present invention relates to a mobile phone comprising transmission voice input means for inputting transmission voice, reception voice output means for outputting reception voice, and telephone communication means for performing telephone communication with other telephones, The present invention relates to a call system including a transmission voice input means for inputting a transmission voice and a handsfree device provided with a reception voice output means for outputting a reception voice, which is installed in a vehicle interior.

  2. Description of the Related Art Conventionally, there is provided a call system that enables a call between another telephone and a mobile phone to be performed by a hands-free call using the hands-free device by mounting the mobile phone on the hands-free device in the vehicle interior. Has been. Further, in recent years, a mobile phone has been brought closer to the hands-free device by providing a short-range wireless communication unit for performing short-range wireless communication based on, for example, the Bluetooth communication standard on both sides of the mobile phone and the hands-free device. A call system that enables a call between another phone and a mobile phone to be established by a hands-free call without establishing a wireless communication line between the two and attaching the mobile phone to the hands-free device. Is also considered.

  By the way, in short-range wireless communication compliant with the Bluetooth communication standard, when both devices are in a positional relationship within the Bluetooth communication range, a wireless communication line is automatically established between the devices. In general, data communication can be started quickly only by one device approaching the other device.

  However, when a configuration that automatically establishes a wireless communication line between the mobile phone and the hands-free device when both devices are within the Bluetooth communication range as described above, There's a problem. That is, when the configuration as described above is applied, in a situation where the communication range of Bluetooth is relatively wide, a person using a mobile phone makes a call with a person using another mobile phone by a handset call. When a person using a mobile phone approaches a car (hands-free device), even if the person using the mobile phone is outside the passenger compartment, a hand-free call from a handset call is contrary to the intention of the person. In some cases, the conversation is automatically switched to a person who uses another telephone.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a mobile phone and a call system using a hands-free device that can be switched from a handset call to a hands-free call at an appropriate timing. There is to do.

  According to the call system using the mobile phone and the hands-free device according to claim 1, the control means transmits the voice transmitted by the voice input means of the mobile phone from the telephone communication means of the mobile phone to another telephone. When the first call processing is performed to transmit the received voice received by the telephone communication means of the mobile phone from the other telephone and output from the received voice output means of the mobile phone. When a predetermined condition is satisfied when the short-distance wireless communication means is capable of short-range wireless communication with the hands-free device, the transmitted voice input by the transmission voice input means of the hands-free device is transmitted to the mobile phone. The telephone communication means transmits the received voice received by the telephone communication means of the cellular phone from the other telephone to the other telephone. Since the second call processing to be output from can be switched to the second call processing, when the call between the other phone and the mobile phone is performed by the handset call, the call between the other phone and the mobile phone is handled. Even in a situation where a hands-free call using a free device can be performed, the handset call is not switched to a hands-free call unless a predetermined condition is satisfied.

  According to the call system using the mobile phone and the hands-free device according to claim 2, the control means transmits the voice transmitted by the voice input means of the mobile phone from the telephone communication means of the mobile phone to another telephone. During the first call processing in which the received voice received by the telephone communication means of the mobile phone from another telephone is output from the received voice output means of the mobile phone, and is integrated with the hands-free device or When a separate condition is established when a separate short-range wireless communication means is capable of short-range wireless communication with a mobile phone, the transmitted voice input by the transmission voice input means of the hands-free device is transmitted to the mobile phone. The telephone communication means transmits the received voice received by the telephone communication means of the cellular phone from the other telephone to the other telephone. Therefore, in this case as well, the call between the other telephone and the mobile phone can be performed by the handset call in the same manner as described in claim 1 above. Even if it is possible to make a call between another phone and a mobile phone by a hands-free call using a hands-free device, the hands-free call can be used as long as the predetermined conditions are not met. There is no switching to a call.

  According to the call system using the mobile phone and the hands-free device according to claim 3, the control means is configured to use the mobile phone as the predetermined condition is that the predetermined operation is performed in the operation means. When a person performs a predetermined operation on a mobile phone or a hands-free device, it is possible to switch from a handset call to a hands-free call at an accurate timing.

  According to the call system using the mobile phone and the hands-free device according to claim 4, the control means sets the predetermined condition that the position detection means detects that the mobile phone is placed at the predetermined position. Since the mobile phone is configured, a person using the mobile phone can switch from a handset call to a hands-free call at an appropriate timing by placing the mobile phone at a predetermined position in the vehicle compartment, for example.

  According to the call system using the mobile phone and the hands-free device according to claim 5, the control means is configured to determine that the vehicle information recognition means has recognized that the information related to the vehicle input from the vehicle is predetermined. Therefore, as information about the vehicle, for example, by recognizing that the vehicle speed is equal to or higher than a predetermined speed, it is possible to recognize that the vehicle is driving and switch from a handset call to a hands-free call at an accurate timing. It becomes possible.

  According to the call system using the mobile phone and the hands-free device according to claim 6, according to the hands-free device, the control means recognizes that the voice input by the transmission voice input means is a predetermined voice. Since it is configured that the recognition by the means is a predetermined condition, a person using the mobile phone can, for example, specify a specific word (for example, “ha”, “n”, “zu”, “fu”, “li”, “ It is possible to switch from a handset call to a hands-free call at an appropriate timing.

  Therefore, according to the first aspect of the present invention, for example, if the person using the mobile phone is outside the passenger compartment, the switching from the handset call to the hands-free call is avoided by not satisfying the predetermined condition. On the other hand, if the person who uses the mobile phone is in the vehicle interior, it is possible to switch from a handset call to a hands-free call by satisfying a predetermined condition. It is possible to switch at an appropriate timing.

  Therefore, according to the second aspect of the present invention, for example, if a person using a mobile phone is outside the passenger compartment, it is possible to avoid switching from a handset call to a hands-free call by not establishing a predetermined condition. On the other hand, if the person who uses the mobile phone is in the vehicle interior, it is possible to switch from a handset call to a hands-free call by satisfying a predetermined condition. It is possible to switch at an appropriate timing.

(First embodiment)
A first embodiment of the present invention will be described below with reference to FIGS. First, FIG. 1 schematically shows the overall configuration of a call system. In the mobile phone 1, the control unit 2 (control unit in the present invention) includes a telephone communication unit 3 (phone communication unit in the present invention) that performs processing related to telephone communication, and a “call start” key for starting a call. , A keypad 4 provided with a number of keys such as a “call end” key for ending a call and “number” keys “0” to “9” for inputting a telephone number (in the present invention).

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 in response to being in the Bluetooth communication range. 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).

  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 specified number of points to which a hands-free switching notification command should be transmitted, it is determined “YES” in step T3, a hands-free switching notification command is output to the Bluetooth communication unit 20, and 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 satisfying a predetermined condition, thereby switching 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. Further, 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.
