Description

  The present invention relates to a technique for notifying a user of an incoming call of a mobile phone in a hands-free device that adds a hands-free call function to a portable mobile phone known as a mobile phone or the like.

  As a hands-free device for adding a hands-free call function to a portable mobile phone, a hands-free device mounted on an automobile is known (for example, Patent Document 1). In such a hands-free device, a user can talk to the other party without holding the mobile phone by providing a microphone and a speaker for inputting / outputting the voice to / from the other party using the mobile phone. And

On the other hand, the incoming call notification technology for a portable mobile phone includes a ringing mode in which a ring tone is output from the built-in speaker of the mobile phone to the mobile phone, and a ring tone is not output from the built-in speaker of the mobile phone when an incoming call is received. There is known a technique of providing a vibration mode (sometimes called a silent mode or a silent mode) for notifying a user of an incoming call by vibrating the mobile phone. In addition, in a mobile phone, a technique is known in which when the mobile phone is mounted on a cradle of a hands-free device, the vibration mode is forcibly released and the ringing mode is set (for example, Patent Document 2). .
JP 2002-18761 A JP 2001-285412 A

  As described above, according to the mobile phone having the vibration mode for notifying the user of the incoming call by vibrating the mobile phone itself without outputting the ring tone from the built-in speaker of the mobile phone, the mobile phone is set to the vibration mode. If it is separated from the body in the set state and attached to the hands-free device, vibration cannot be transmitted to the user, and there is a problem that the incoming call cannot be notified to the user.

  On the other hand, in the mobile phone to which the technology of Patent Document 2 is applied, when the mobile phone is attached to the hands-free device, the vibration mode is canceled and the ring mode is set. An incoming call can be notified. However, this technique cannot be applied to an existing mobile phone that does not have a mode control function according to whether or not a cradle is attached.

  Therefore, the present invention notifies a user of an incoming call to the mobile phone without any trouble even when the attached mobile phone is set to a mode in which a ring tone is not output from the built-in speaker of the mobile phone when an incoming call is received. It is an object of the present invention to provide a hands-free device that can be used.

To achieve the above object, the present invention provides a speaker for outputting audio received by a connected mobile phone;
A microphone for inputting a voice transmitted by the connected mobile phone; an incoming call detection unit for detecting an incoming call of the connected mobile phone; a ring tone detection unit for detecting an output of a ring tone of the connected mobile phone; Generates a predetermined ringtone when the ringtone detection unit cannot detect the output of the ringtone of the mobile phone within a predetermined monitoring period after the incoming call detection unit detects the incoming call of the mobile phone And a ring tone generation / output unit for output.

  Here, the ring tone detection unit may detect the output of the ring tone of the mobile phone based on, for example, a voice input from the microphone. Alternatively, the ring tone detection unit detects, for example, an output of a ring tone of the mobile phone based on a voice output that the mobile phone outputs to an external device input / output interface included in the mobile phone. Also good.

  According to such a hands-free device, it is determined whether or not the mobile phone is in a mode in which no ring tone is output from the speaker built in the mobile phone, directly from the output of the ring tone of the mobile phone when the mobile phone receives an incoming call. Thus, when in a mode in which no ring tone is output, the hands-free device generates and outputs a ring tone.

Therefore, it is possible to reliably notify the user of an incoming call to the mobile phone regardless of whether or not the mobile phone has a cradle mounted or not.
Here, the hands-free device as described above further acquires information indicating the model of the mobile phone from the mobile phone via the input / output interface for the external device, and according to the model of the mobile phone. You may make it provide the monitoring period setting part which sets the period of length as the said monitoring period.

  In this way, the monitoring period can be set according to the period from the incoming call of the mobile telephone for each model to the output of the ringtone. Therefore, it is possible to reliably detect the mode of presence / absence of ringtone output even for a mobile phone having a long period from incoming call to ringtone output, and for a mobile phone having a short period from incoming call to ringtone output. After that, the ringtone can be output from the hands-free device immediately.

  Further, in the above-described hands-free device, when the ring tone detection unit detects the output of the ring tone of the mobile phone within the monitoring period, the mobile phone serves as an input / output interface for an external device. You may make it provide the ringtone relay output part which outputs the audio | voice output to output from a speaker.

  In this way, even when the mobile phone is a mobile phone that outputs a ring tone from the external device input / output interface even though the mobile phone does not output a ring tone from the built-in speaker of the mobile phone, the mobile phone When the mobile phone is in a mode that does not output a ring tone from the built-in speaker of the mobile phone, the hands-free device can notify the user of the incoming call using the ring tone output from the mobile phone to the external device input / output interface. It becomes like this.

  Further, in this case, the operation mode of the mobile phone is further changed from the mobile phone to the hands-free device via the external device input / output interface provided in the mobile phone connected to the mobile phone. A mobile phone mode acquisition unit is provided for acquiring information on whether or not the ringer mode is output from the built-in speaker. In the ringing tone relay output unit, the mobile phone mode acquisition unit is configured so that the operation mode of the mobile phone is a ringer mode. If the mobile phone does not output from the speaker the audio output that the mobile phone outputs to the input / output interface for the external device when the information indicating that the mobile phone is present is obtained, For mobile phones that can acquire the phone, when the mobile phone outputs a ring tone from the built-in speaker of the mobile phone It is possible to prevent the output of the ring tone from the hands-free device.

  In addition, the operation mode of the mobile phone from the mobile phone via the input / output interface for external equipment provided in the mobile phone connected to the hands-free device, and the built-in speaker provided in the mobile phone with a ring tone. A mobile phone mode acquisition unit that acquires information on whether or not in silent mode is not output from the mobile phone, and in the ring tone generation output unit, the mobile phone mode acquisition unit sets the operation mode of the mobile phone to silent mode. If the incoming call detection unit detects the incoming call of the mobile phone when the information indicating that the mobile phone is present, the ring tone does not wait for the ring tone detection unit to detect the output of the ring tone within the monitoring period. May be generated and output.

  In this way, for a mobile phone that can acquire such information by the hands-free device, when a ring tone is received from a built-in speaker provided in the mobile phone, the incoming call Immediately, a ringtone can be output from the hands-free device.

  Alternatively, the above-described handsfree device is further connected to the above-mentioned hands-free device via the external device input / output interface provided in the mobile phone. A mobile phone mode acquisition unit that acquires information on whether or not the ringer mode is output from the mobile phone, and in the ring tone generation and output unit, the mobile phone mode acquisition unit is in a ringer mode. When the information indicating this is acquired, it is also preferable not to output the ringtone regardless of whether the ringtone detection unit detects the output of the ringtone within the monitoring period.

  In order to achieve the above object, the present invention provides a hands-free device that adds a hands-free call function to a connected mobile phone, a speaker that outputs voice received by the connected mobile phone, and a connected mobile phone Operation mode setting for setting the operation mode of the mobile phone to the ringer mode for outputting the ring tone from the built-in speaker of the mobile phone when the mobile phone is connected to the microphone for inputting the voice transmitted by the phone Part.

  According to such a hands-free device, for a mobile phone whose operation mode can be set from the hands-free device, when the mobile phone is connected, the mobile phone outputs a ring tone from the built-in speaker of the mobile phone itself. Can be set to ringer mode. Therefore, even if the operation mode of the mobile phone is set to silent mode that does not output the ring tone from the built-in speaker before connection to the hands-free device, the mobile phone will receive incoming calls while it is connected to the hands-free device. Can be notified to the user by causing the mobile phone itself to output a ring tone from the built-in speaker.

  Here, the hands-free device further includes that when the connection of the mobile phone is released, the operation mode of the mobile phone is not in a silent mode in which a ring tone is not output from a built-in speaker included in the mobile phone. You may make it provide the audio | voice message output part which outputs the predetermined | prescribed audio | voice message to notify from the said speaker. In this way, when the mobile phone is in silent mode in which the ring tone is not output from the built-in speaker before the hands-free device is connected, the user can remove the mobile phone from the hands-free device and then Forgetting to return to the original silent mode.

  Or, when the mobile phone is connected to the hands-free device, the operation mode of the mobile phone is in a ringer mode for outputting a ring tone from a built-in speaker included in the mobile phone when the mobile phone is connected. Alternatively, a mobile phone mode acquisition unit that acquires information on whether the mobile phone is in a silent mode that does not output a ring tone from a built-in speaker included in the mobile phone, and the information acquired by the mobile phone mode acquisition unit is an operation mode of the mobile phone. Indicates that the mobile phone is in silent mode, and when the connection of the mobile phone is released, an operation mode recovery unit is provided to set the operation mode of the mobile phone to silent mode. In the mode setting unit, after the mobile phone mode acquisition unit acquires the information, at least the When the obtained information is the operation mode of the mobile phone indicates that it is in silent mode, the operation mode of the mobile phone, may be set to ringer mode.

  Thus, for a mobile phone that can acquire such information from the hands-free device, the mobile phone is provided with a ring tone while the mobile phone is connected to the hands-free device. When the connection of the mobile phone to the hands-free device is canceled while the ringer mode output from the built-in speaker is set, the operation mode of the mobile phone can be returned to the original operation mode before the connection.

  Each hands-free device described above may be connected to a mobile phone via wired communication or may be connected to the mobile phone via short-range wireless communication.

  As described above, according to the present invention, even when the attached mobile phone is set to a mode in which a ring tone is not output from the built-in speaker of the mobile phone when an incoming call is received, the incoming call to the mobile phone is obstructed. It is possible to provide a hands-free device that can notify the user without any problem.

Hereinafter, embodiments of the present invention will be described.
First, the first embodiment will be described.
FIG. 1 shows the configuration of the hands-free device according to the first embodiment.
As shown, the hands-free device includes a hands-free processing device 1, a cradle 2 that holds a portable mobile phone 50, an input device 3, a display device 4, a microphone 5, and a speaker 6.
The hands-free processing device 1 includes a mobile telephone interface 11, a control unit 12, a voice generation unit 13, a voice processing unit 14, a mixing unit 15, and a ring tone detection unit 16. The audio processing unit 14 includes an echo canceller 141 and an output audio adjustment unit 142.
Here, FIG. 2 shows an example of a signal interface between the mobile telephone 50 and the hands-free processing device 1.
As shown in the figure, as signals to be input / output to / from the handsfree processing device 1 of the mobile phone 50, in addition to various ground signals, reception for transmitting received call voice from the mobile phone 50 to the handsfree processing device 1 is performed. Voice signal (terminal number 10), transmission voice signal (terminal number 2) for transmitting a transmission voice signal from the hands-free processing device 1 to the mobile phone 50, commands from the mobile phone 50 to the hands-free processing device 1, and other control data Downstream serial signal (terminal number 7) for transmitting data, upstream serial signal (terminal number 6) for transmitting commands and other control data from the handsfree processing device 1 to the mobile telephone 50, handsfree processing An operation unit control signal (terminal numbers 12 and 13) for controlling validity / invalidity of the operation unit of the mobile telephone 50 from the device 1; Unit presence / absence (terminal number 14) for notifying the mobile phone 50 of the presence or absence of connection of the hands-free processing device 1 from the hands-free processing device 1, and unit power control for controlling the power of the hands-free processing device 1 from the mobile phone 50 A signal (terminal number 15) is provided. When the mobile phone 50 performs data communication instead of voice communication, the signal lines of terminal numbers 2 and 10 are used for transmission / reception of data signals instead of transmission / reception of reception voice signals and transmission voice signals. In this case, the signal lines of terminal numbers 4 and 5 are used for transmission of a synchronization signal for transmitting and receiving a data signal between the mobile telephone 50 and the hands-free processing device 1.

  Here, the various signals described above are input / output between the mobile telephone 50 and the mobile telephone interface 11 via a connector provided in the cradle 2 and a connector provided in the mobile telephone 50. That is, the connector of the mobile phone 50 is configured to be connected to a connector provided on the cradle 2 when the mobile phone 50 is mounted on the cradle 2.

  Returning to FIG. 1, during a voice call of the mobile phone 50 attached to the cradle 2 of the hands-free device, the mobile phone 50 outputs a voice signal received from the other party to the mobile phone interface 11 as a received voice signal. Then, the mobile telephone interface 11 sends the received reception audio signal to the output audio adjustment unit 142 of the audio processing unit 14. The output audio adjustment unit 142 performs volume adjustment and loudness compensation processing on the input reception audio signal, and outputs the result from the speaker 6 via the mixing unit 15. Here, the mixing unit 15 mixes the sound output from the output sound adjusting unit 142 and the sound generated by the sound generating unit 13 at the mixing ratio instructed by the control unit 12 and outputs the mixed sound from the speaker 6. In addition, the mixing unit 15 outputs only the sound output from the output sound adjusting unit 142 as the mixing ratio 100% during the voice call of the mobile phone 50.

  On the other hand, during the voice call of the mobile phone 50 attached to the cradle 2 of the hands-free device, the voice signal input from the microphone 5 is the voice circulated from the speaker 6 to the microphone 5 in the echo canceller 141 of the voice processing unit 14. After the echo cancellation processing for removing the component is performed, it is sent to the mobile telephone 50 as a transmission voice signal via the mobile telephone interface 11. Then, it is transmitted from the mobile telephone 50 to the other party.

Next, the control unit 12 transmits / receives various commands and control data to / from the mobile telephone 50 through the mobile telephone interface 11 using the uplink serial signal and the downlink serial signal.
Hereinafter, the control operation of the ring tone when the mobile phone 50 receives a call in the hands-free processing apparatus 1 will be described.
FIG. 3 shows the procedure of the ring tone control process performed by the control unit 12.
As shown in the figure, in this process, an incoming call from the mobile telephone 50 is awaited (step 302). The presence / absence of this incoming call is determined based on the downlink serial signal “incoming call display (on)” that the mobile telephone 50 outputs when receiving an incoming call.
If an incoming call from the mobile telephone 50 occurs, a timer is started (step 304). Here, the timeout time of this timer is, for example, 5 seconds. Then, the reception of the downlink serial signal “tone type (ringtone)” from the mobile telephone 50 (step 306), the detection of the received voice of the ringtone detector 16 (step 308), and the timer timeout (step 310). Monitor outbreaks.

  Here, the downlink serial signal “tone type (ringing tone)” is obtained before the mobile phone 50 outputs a voice signal of a predetermined ringing tone (a 2000-second sound of 16 Hz modulation for 1 second every 2 seconds) as a received voice signal. Is output from the mobile telephone 50. In addition, the mobile telephone 50 is configured such that a ringing tone is output from the built-in speaker of the mobile telephone 50 when an incoming call is received, and the mobile telephone 50 itself is vibrated without outputting the ringtone from the built-in speaker of the mobile telephone 50 when an incoming call is received. A vibration mode for notifying the user of an incoming call is provided. In the present embodiment, the mobile phone 50 targeted by the hands-free device is a mobile phone that outputs the ringtone as a received voice signal even when the ringtone is not output from the built-in speaker provided in the mobile phone 50 in the vibration mode. 50 and the mobile phone 50 that does not output the ringtone as a received voice signal when the ringtone is not output from the built-in speaker provided in itself in the vibration mode.

  Then, the ring tone detector 16 detects the received voice according to the amplitude of the received voice signal. Since the maximum amplitude of the received voice signal voltage input from the mobile telephone 50 is 100 mV to 1.5 V, the received voice signal is detected when, for example, the received voice signal voltage amplitude of 50 mV or more is detected. It can be performed by detecting.

  The control unit 12 receives the downlink serial signal “tone type (ringing tone)” from the mobile telephone 50 (step 306) or the reception of the ringing tone detection unit 16 before the timer timeout occurs (step 310). If the voice detection (step 308) occurs, the timer is stopped (step 320), and the downlink serial signal “incoming display (off)” is received from the mobile telephone 50 (step 322), or the user input device 3 The process waits for the occurrence of an off-hook operation (step 324), and returns to step 302 if any occurs. Here, the mobile telephone 50 transmits a downlink serial signal “incoming call display (off)” when the state changes from the incoming call state to another state such as a busy state. The on-hook operation on the input device 3 by the user is an operation performed when the user starts a call in response to an incoming call.

  On the other hand, before receiving the downlink serial signal “tone type (ringtone)” from the mobile telephone 50 (step 306) or before detecting the incoming voice of the ringtone detecting unit 16 (step 308), the timeout of the timer has occurred. If generated, the voice generation unit 13 is caused to generate a predetermined ringtone, and the mixing unit 15 is caused to output the ringtone generated by the voice generation unit 13 to the speaker 6 (step 312).

  Then, it waits for the reception of the downlink serial signal “incoming display (off)” from the mobile telephone 50 (step 320) or the occurrence of an off-hook operation on the user input device 3 (step 322). The generation of the ring tone by the voice generation unit 13 and the output of the ring tone by the mixing unit 15 are stopped (step 318), and the process returns to step 302.

The ring tone control processing in this embodiment has been described above.
Here, FIG. 4 shows an operation example of the hands-free processing device 1 that performs such ringtone control processing.
FIG. 4A is an operation example when the mobile phone 50 attached to the hands-free device is set to the ringing mode, and FIG. 4B is an operation example when the mobile phone 50 attached to the hands-free device is set to the vibration mode. Is the case.
First, a case where the mobile phone 50 attached to the hands-free device is set to the ringing mode will be described.
In this case, when there is an incoming call (SETUP) 431 from the mobile telephone network to the mobile telephone 50, the mobile telephone 50 responds to the network with an alerting (ALERT) 432, and the hands-free processing device 1 sends a downstream serial signal “incoming display (ON ) "411 is output. Then, the control unit 12 of the hands-free processing device 1 that has received the downstream serial signal “incoming display (ON)” 411 starts 401 a timer.

  On the other hand, the mobile phone 50 thereafter transmits the downlink serial signal “calling number notification” 412 + “dial” 413 + “dial completion” 414 and the downlink serial signal “calling number notification” 415 + “dial” 416 + “dial completion” 417. After notifying the hands-free processing device 1 of the call source and destination numbers, the serial number “tone type (ringing tone)” 418 is output to the hands-free processing device 1 and the ring tone is received as a received voice signal. Is output 419. In addition, a ring tone is output from the built-in speaker of the mobile phone 50 to notify the user of the incoming call. At this time, in the hands-free processing device 1, the timer is stopped 402 in accordance with the detection of the downstream serial signal “tone type (ringing tone)” 418 and the ringing tone 419 as the received voice signal 402. Therefore, the hands-free processing device 1 does not generate and output a ring tone. In the hands-free processing device 1, the ring tone input as the incoming sound from the mobile phone 50 is output from the speaker 6 of the hands-free device via the voice processing unit 14. However, when the mobile phone 50 attached to the hands-free device does not output a ring tone from the built-in speaker provided in the mobile phone 50 in the vibration mode, the mobile phone 50 does not necessarily output the ring tone as a received voice signal. If it is guaranteed that there is an incoming call sound from the mobile telephone 50 as an incoming call sound, it may not be output from the speaker 6 of the hands-free device.

  Thereafter, when the user performs an off-hook operation 403 on the input device 3 of the hands-free device, the control unit 12 of the hands-free processing device 1 outputs an upstream serial signal “hook switch (start)” 420 to the mobile phone 50. Then, the occurrence of an off-hook operation is notified. Receiving this notification, the mobile telephone 50 notifies the network of connection (CONN) 433. Further, the mobile telephone 50 outputs the downlink serial signal “tone type (tone off)” 421 to the hands-free processing device 1, and then stops the output 422 of the ringtone as a received voice signal to the hands-free processing device 1. .

When the mobile telephone 50 receives the connection response (CONN ACK) 434 from the network, the mobile telephone 50 transitions to a busy state, and sends the downstream serial signal “incoming call display (off)” 423 and the downstream serial signal “ "In-call display (ON)" 424 is output.
Thereafter, in a call state, as described above, the voice input from the microphone 5 of the hands-free device is sent to the mobile telephone 50 and transmitted to the network by the mobile telephone 50, and the voice received by the mobile telephone 50 from the network is hands-free. 404, 425, and 435 which are sent to the processing device 1 and output from the speaker 6 of the hands-free device.

  Thereafter, when the user performs an on-hook operation with respect to the input device 3 of the hands-free device 405, the control unit 12 of the hands-free processing device 1 sends the uplink serial signal “hook switch (end)” 426 to the mobile phone. 50 to notify the occurrence of an on-hook operation. Upon receiving this notification, the mobile telephone 50 notifies the network of a disconnection (DISK) 436. If a release (REL) 437 is received from the network as a response, a downstream serial signal “in-call indication (off)” 427 is output to the hands-free processing device 1 and a release completion (REL COMP) 438 is sent to the network. In response to this, the current call processing is terminated.

Next, a case where the mobile phone 50 attached to the hands-free device is set to the vibration mode will be described.
In this case, when there is an incoming call (SETUP) 481 from the mobile telephone network to the mobile telephone 50, the mobile telephone 50 responds to the network with an alert (ALERT) 482, and the hands-free processing device 1 sends a downstream serial signal “incoming call display (ON ) "461 is output. Then, the control unit 12 of the hands-free processing device 1 that has received the downstream serial signal “incoming display (ON)” 461 starts a timer 451.

  On the other hand, the mobile phone 50 thereafter transmits the downstream serial signal “calling number notification” 462+ “dial” 463+ “dial completion” 464 and the downstream serial signal “notification of incoming number” 465+ “dial” 466+ “dial completion” 467. Thus, the call source and destination numbers are notified to the hands-free processing device 1.

  In this case, thereafter, the mobile telephone 50 does not output the downlink serial signal “tone type (ringing tone)” to the hands-free processing device 1 and does not output a ringing tone as a received voice signal. Therefore, a timeout occurs in the hands-free processing device 1 452, a ringing tone is generated in the hands-free processing device 1 and a ringing tone output 453 is output from the speaker 6, and the user is notified of the incoming call.

  Thereafter, as in the case of FIG. 4a, when the user performs an off-hook operation 454 with respect to the input device 3 of the hands-free device, the generation and output of the ringtone are stopped. Then, as described above, the state transits to a busy state, and the voices input from the microphones 468-470, 483-484 and the hands-free device are sent to the mobile telephone 50 and transmitted to the network by the mobile telephone 50. The voice received from the network is sent to the hands-free processing device 1 and output from the speaker 6 of the hands-free device 456, 471, 485.

After that, when the user performs an on-hook operation with respect to the input device 3 of the hands-free device in a call state, the call is disconnected and released as in the case of FIG. 4a.
Also, if the mobile phone 50 receives a disconnection (DISK) 486 from the network during a call (when an on-hook operation is performed on the other side of the call), the mobile phone 50 will receive the user's hands-free operation thereafter. Waiting for the reception of the upstream serial signal “hook switch (end)” 472 from the control unit 12 of the hands-free processing device 1 performed in response to the on-hook operation 457 for the input device 3 of the device, release to the network (REL) 487 Is transmitted, and after waiting for a response of release completion (REL COMP) 488 from the network, the downstream serial signal “in-call display (off)” 473 is output to the hands-free processing device 1, and the processing of the current call is terminated. .

The first embodiment of the present invention has been described above.
As described above, according to the first embodiment, it is determined whether or not the mobile phone 50 is set in the vibration mode directly from the output of the ringtone of the mobile phone 50. The hands-free processing device 1 generates and outputs a ringtone when an incoming call is received. Therefore, it is possible to reliably notify the user of the incoming call of the mobile telephone 50.

Hereinafter, a second embodiment of the present invention will be described.
In the second embodiment, the mobile phone 50 targeted by the hands-free device includes a mobile phone 50 having a function of notifying the hands-free processing device 1 of the setting state of its own ringing mode / vibration mode by a down serial signal. And a mobile telephone 50 that does not have a function of performing such notification. In addition, the mobile telephone 50 having a function of notifying the hands-free processing device 1 whether or not to output a ring tone as a received voice signal in the vibration mode by the down serial signal and a function of performing such notification are not provided. A mobile phone 50 is included. In addition, a mobile phone 50 having a function of notifying the hands-free processing device 1 of the type (manufacturer, model number, etc.) of its own model by a downlink serial signal and a mobile phone 50 not having a function of performing such notification are provided. Including.

  Then, when the mobile phone 50 is attached to the cradle 2, the control unit 12 of the hands-free processing device 1 according to the second embodiment uses the uplink serial signal to set the ringing mode / vibration mode information of the mobile phone 50. Information about whether or not to output a ring tone as a received voice signal when the mobile phone 50 is in the vibration mode and information on the type of the mobile phone 50, and information notified from the mobile phone 50 by a downlink serial signal Hold. However, as described above, some or all of the information is not notified to the hands-free processing device 1 depending on the mobile phone 50. The mounting of the mobile phone 50 to the cradle 2 can be detected by providing a mechanical switch that is turned on / off in accordance with the mounting / removal of the mobile phone 50 on the cradle 2. It can also be detected from the value of the power control signal or other signals.

And the control part 12 of the hands-free processing apparatus 1 which concerns on this 2nd Embodiment replaces with the ringtone control process (refer FIG. 3) in the said 1st Embodiment, and performs the ringtone control process shown in FIG.
As shown in the figure, in the ringing tone control process according to the second embodiment, the mobile phone 50 waits for an incoming call (step 502). If an incoming call of the mobile telephone 50 occurs, it is checked whether or not the mobile telephone 50 is in the ringing mode (step 504). If the mobile telephone 50 is in the ringing mode, the downlink serial signal “incoming display (off)” from the mobile telephone 50 is checked. ”(Step 530) or the occurrence of an off-hook operation on the user's input device 3 (step 532). If either one occurs, the process returns to step 502.

  On the other hand, if the mobile telephone 50 is not in the ringing mode (step 504), it is checked whether the mobile telephone 50 is in the vibration mode (step 506). If the mobile telephone 50 is in the vibration mode, a predetermined ringtone is sent to the voice generation unit 13. At the same time, the mixing unit 15 outputs the ringtone generated by the voice generation unit 13 to the speaker 6 (step 520). Then, it waits for the reception of the down serial signal “incoming display (off)” from the mobile telephone 50 (step 522) or the occurrence of an off-hook operation for the user input device 3 (step 524). The generation of the ring tone by the voice generation unit 13 and the output of the ring tone by the mixing unit 15 are stopped (step 526), and the process returns to step 502.

  On the other hand, when the mobile telephone 50 is neither in the ringing mode nor in the vibration mode (steps 504 and 506), that is, when the notification of the ringing mode / vibration mode setting state cannot be received from the mobile telephone 50, the mobile telephone It is checked whether or not 50 is a device that does not output a ring tone as a received voice signal in the vibration mode (step 508), and if the mobile phone 50 is not a device that does not output a ring tone as a received voice signal in the vibration mode, that is, When the mobile phone 50 is a device that outputs a ringtone as a received voice signal when in the vibration mode, or the mobile phone 50 cannot receive a notification as to whether or not it outputs a ringtone as a received voice signal when in the vibration mode The voice generation unit 13 generates a predetermined ringtone and the mixing unit 15 transmits the voice generation unit 1. There causing the output to the speaker 6 of the generated ringtone (step 520). At this time, the control unit 12 controls the mixing unit 15 so as not to output the received audio signal from the speaker 6. Then, it waits for the reception of the down serial signal “incoming display (off)” from the mobile telephone 50 (step 522) or the occurrence of an off-hook operation for the user input device 3 (step 524). The generation of the ring tone by the voice generation unit 13 and the output of the ring tone by the mixing unit 15 are stopped (step 526), and the process returns to step 502.

  Next, when it is determined in step 508 that the mobile phone 50 is a device that does not output a ring tone as a received voice signal in the vibration mode, a time-out period corresponding to the type of the mobile phone 50 is set ( Step 510). Here, the control unit 12 outputs the downlink serial signal “incoming display (on)” when the model type and the mobile phone 50 which is the model of the type are set to the vibration mode in advance, and then receives the received voice. A table describing the correspondence with the maximum time until the start of output of a ring tone as a signal is stored. Here, as the timeout time, the maximum time described in the table is set corresponding to the type of mobile phone 50 model. However, if the mobile phone 50 cannot receive the model type notification, a fixed value, for example, 5 seconds is set as the timeout time.

  Next, a timer is started (step 512), the downlink serial signal “tone type (ringtone)” is received from the mobile telephone 50 (step 514), and the received voice is detected by the ringtone detector 16 ( Step 516), the occurrence of a timer timeout (Step 518) is monitored. Then, the control unit 12 receives the downlink serial signal “tone type (ringing tone)” from the mobile telephone 50 before the time-out of the timer (step 518) (step 512) or the ringing tone detection unit 16 receives it. If voice detection (step 514) occurs, the timer is stopped (step 528), whether the downlink serial signal “incoming display (off)” is received from the mobile telephone 50 (step 530), or the user input device 3 The process waits for the occurrence of an off-hook operation (step 532), and returns to step 502 if any occurs.

  On the other hand, before receiving the downlink serial signal “tone type (ringing tone)” from the mobile telephone 50 (step 514) or detecting the received voice of the ringing tone detecting unit 16 (step 517), the timer time-out occurs. If it occurs (step 518), the voice generation unit 13 generates a predetermined ringtone, and the mixing unit 15 outputs the ringtone generated by the voice generation unit 13 to the speaker 6 (step 520). . Then, it waits for the reception of the down serial signal “incoming display (off)” from the mobile telephone 50 (step 522) or the occurrence of an off-hook operation for the user input device 3 (step 524). The generation of the ring tone by the voice generation unit 13 and the output of the ring tone by the mixing unit 15 are stopped (step 526), and the process returns to step 502.

The second embodiment has been described above.
As described above, according to the second embodiment, the mobile phone 50 capable of acquiring the model information by the hands-free processing device 1 is monitored according to the period from the incoming call of the mobile phone 50 to the output of the ring tone for each model. A period can be set. Therefore, the mobile phone 50 having a long period from the incoming call to the ring tone output can reliably detect the mode of the presence or absence of the ring tone output, and the mobile telephone 50 having a short period from the incoming call to the ring tone output. After the incoming call, the ringtone can be output from the hands-free processing device 1 as soon as possible.

  By the way, as shown in FIG. 6, the connection form between the hands-free processing device 1 and the mobile phone 50 in each of the above embodiments is the Bluetooth (registered trademark), IEEE 802.11 series, IrDa, or the like.

A sound detection unit 1618 is provided for receiving the downlink serial signal “tone type (ringtone)” from the mobile telephone 50 and detecting the received voice of the ringtone detection unit 16 (steps 306 and 308) in the ringtone control process. Instead, the detection of the output of the ringtone of the mobile telephone 50 from the built-in speaker of the mobile telephone 50 in the external ringtone detector 1618 may be determined. That is, in the ring tone control process of the first embodiment, after the timer is started (step 304), if the external ring tone detector 1618 detects a ring tone before the timer times out, the process proceeds to step 320. If the timer times out before the external ring tone detector 1618 detects the ring tone (step 310), the process proceeds to step 312. In the ring tone control process of the second embodiment, after the timer is started (step 512), if the external ring tone detector 1618 detects a ring tone before the timer times out, the process proceeds to step 528. If the timer times out before the external ring tone detector 1618 detects a ring tone (step 518), the process proceeds to step 520.

  In the above embodiment, as shown in FIG. 6, an electric field strength sensor 7 for detecting the electric field strength in the transmission / reception frequency band of the mobile telephone 50 is provided, and the mobile phone 50 moves in response to reception of the downstream serial signal “incoming display (ON)”. Instead of determining whether or not the telephone 50 has received an incoming call, the mobile telephone 50 is determined to receive an incoming call according to the electric field intensity pattern detected by the electric field intensity sensor 7 (for example, a continuation of a strong electric field of a predetermined period for a certain period or more). It may be.

  Moreover, in the above embodiment, the control unit 12 replaces the ring tone generation output in the hands-free processing device 1 or, together with the ring tone generation output in the hands-free processing device 1, with the mobile phone 50 on the display device 4. A predetermined event for notifying the user of an incoming call may be performed. In this case, the control unit 12 displays a predetermined display for notifying the user of the incoming call of the mobile phone 50 on the display device 4 even when the output of the ringtone of the mobile phone 50 is detected. Also good. However, the display form when the ringtone output of the mobile phone 50 is not detected is a form in which the incoming call is transmitted to the user more strongly than the display form when the output of the ringtone of the mobile phone 50 is detected. And For example, the display form when the ring tone output of the mobile telephone 50 is not detected is the flashing of the entire surface of the display device 4, and the display form when the ringtone output of the mobile telephone 50 is detected is Suppose that a graphic indicating that a call is being received flashes.

Hereinafter, a third embodiment of the present invention will be described.

If the mobile phone 50 is attached, an uplink serial signal “hands-free notification (ON)” is transmitted to the mobile phone 50 (step 704). If the downstream serial signal “hands-free confirmation (ON)” is received as a response (step 706), the mobile telephone 50 is set to the ringing mode by the upstream serial signal (step 708).

Here, when receiving the uplink serial signal “hands-free notification (ON)”, the mobile telephone 50 starts input / output of the reception voice signal and the transmission voice signal, and transmits the downlink serial signal “hands-free confirmation (ON)”. To do.
Next, the control unit 12 monitors the removal of the mobile phone 50 from the cradle 2 (step 710). If the mobile phone 50 is removed from the cradle 2, the control unit 12 causes the voice generation unit 13 to move the mobile phone 50 to the vibration mode. A voice message alerting the user that the phone is not in the phone, for example, “The mobile phone 50 is not currently set in the manner mode. Please set the manner mode in the mobile phone 50”. The mixing unit 15 outputs the voice message generated by the voice generation unit 13 to the speaker 6 (step 712).

Then, the processing returns to step 702.
Heretofore, the third embodiment of the present invention has been described.
As described above, according to the third embodiment, for the mobile phone 50 in which the ringing mode can be set from the hands-free processing device 1, the mobile phone 50 is set to the vibration mode before connection to the hands-free device. However, the mobile phone 50 can be set to the ringing mode and the ring tone can be output from the built-in speaker of the mobile phone 50 while it is connected to the hands-free device. In addition, when the mobile phone 50 is in the vibration mode before the hands-free device is connected, the user forgets to return the mobile phone 50 to the original vibration mode after removing the mobile phone 50 from the hands-free device. Can be suppressed.
