Description

The present invention relates to an on-vehicle incoming call system and an on-vehicle incoming call program.

An in-vehicle hands-free device capable of communicating with a mobile phone is known (see Patent Document 1). In Patent Document 1, an in-vehicle hands-free device controls a speaker and a microphone to make a hands-free call when a mobile phone receives a call. In Patent Document 1, when a call arrives in a state where a hands-free call cannot be received, the user is notified that the response is on hold.

JP, 2009-159237, A

However, in Patent Document 1, there is a problem that if the mobile phone does not have the response holding function, the response cannot be held. In particular, in Patent Document 1, since the user is notified that the response is being held, the user is informed that the response is being held despite the fact that the mobile phone cannot actually hold the response. There is a possibility of misunderstanding.
The present invention has been made in view of the above problems, and an object of the present invention is to provide a technique capable of holding a response even if the mobile phone terminal does not have a response holding function.

In order to achieve the above-mentioned object, an in-vehicle incoming call system of the present invention is an in-vehicle incoming call system that communicates with a mobile phone terminal, and includes an incoming call detection unit that detects that the mobile phone terminal has received a voice call, and a voice call. When a call is received, a response holding voice is transmitted to the mobile phone terminal, and a response holding unit for instructing to establish a voice call and send the response holding voice to the calling telephone terminal is provided.

In order to achieve the above-mentioned object, an in-vehicle call reception program of the present invention includes a computer of an in-vehicle call reception system that communicates with a mobile phone terminal, an incoming call detection unit that detects that the mobile phone terminal has received a voice call, and a voice call. When an incoming call is received, the mobile phone terminal is caused to function as a response holding unit that transmits a response holding voice and establishes a voice call to instruct the calling telephone terminal to send the response holding voice.

In the above configuration, the in-vehicle call receiving system sends the response hold voice to the mobile phone terminal, and commands the mobile phone terminal to send the response hold voice, so that the mobile phone terminal does not have the response hold function. However, the response can be held. That is, the in-vehicle call receiving system can realize the response holding function instead of the mobile phone terminal.

It is a block diagram of a vehicle-mounted incoming call system. 2A is a diagram showing an incoming call notification image, and FIG. 2B is a diagram showing a response hold image. 3A to 3D are operation explanatory diagrams of the on-vehicle incoming call system and the smartphone. It is a flowchart of a response holding process.

Here, an embodiment of the present invention will be described in the following order.

(1) Configuration of in-vehicle incoming call system:
FIG. 1 is a block diagram showing the configuration of an on-vehicle incoming call system 10 according to an embodiment of the present invention. The in-vehicle incoming call system 10 is an in-vehicle device mounted on a vehicle and communicates with the smartphone 100 (100A, 100B) as a mobile phone terminal. A user is in a vehicle equipped with the in-vehicle incoming call system 10 while carrying the smartphone 100. Note that FIG. 1 shows that the smartphone 100 is not mounted on the vehicle, and does not show that the smartphone 100 exists outside the vehicle. The vehicle-mounted incoming call system 10 includes a control unit 20 and a recording medium 30. The control unit 20 includes a CPU, a RAM, a ROM, and the like, and executes the in-vehicle incoming call program 21 stored in the recording medium 30 or the ROM.

The recording medium 30 records the response hold voice data 30a. The response hold voice data 30a is voice data for outputting a response hold message. The response hold message is a message for transmitting to the caller that the user of the smartphone 100 cannot receive the call. The answer hold message is not particularly limited, but as an example, "I cannot answer the call right now. Excuse me, but please call back after a while. ] Is mentioned. In the present specification, receiving a voice means that a voice call is established between the caller's terminal and the smartphone 100, and the user of the smartphone 100 has a voice conversation with the caller.

The vehicle includes a communication unit 40, a touch panel display 41, a microphone 42, and a speaker 43. The communication unit 40 is a communication circuit for performing near field communication with the smartphone 100 in the vehicle. In the present embodiment, the communication unit 40 adopts Bluetooth (registered trademark) as a communication standard.

The pairing between the vehicle-mounted call receiving system 10 and the smartphone 100 has been completed in advance, and the HFP (Hands-Free Profile) profile has been activated. The HFP profile is a profile for causing the in-vehicle call receiving system 10 to function as a hands-free terminal. The in-vehicle call receiving system 10 and the smartphone 100 allow the in-vehicle call receiving system 10 to function as a hands-free terminal by exchanging commands and data defined in the HFP profile.

The touch panel display 41 includes a display that outputs a video based on the video signal generated by the control unit 20, and a touch panel that detects a touch operation of the user's finger or the like on the display. The microphone 42 is a device that converts collected sound into an electric signal. The speaker 43 outputs sound based on the sound signal output by the control unit 20.

Next, the software configuration of the vehicle-mounted call receiving system 10 will be described. The in-vehicle incoming call program 21 includes an incoming call detection module 21a and a response holding module 21b. The incoming call detection module 21a and the response holding module 21b are program modules that cause the control unit 20 as a computer to function as an incoming call detection unit and a response holding unit, respectively.

With the function of the incoming call detection module 21a, the control unit 20 detects that the smartphone 100 as a mobile phone terminal has received a voice call. When the smartphone 100 receives a voice call from the calling telephone terminal 200, which is the caller's terminal, via the mobile phone communication network, the smartphone 100 transmits an incoming call notification command indicating that the voice call has been received to the in-vehicle incoming call system 10. By the function of the incoming call detection module 21a, the control unit 20 detects that the smartphone 100 has received a voice call by receiving the incoming call notification command. The incoming call notification command includes data indicating the telephone number and the caller name associated with the calling telephone terminal 200.

When the incoming call notification command is received, the control unit 20 displays the incoming call notification image on the touch panel display 41 by the function of the incoming call detection module 21a, and accepts the user's operation on the touch panel display 41.

FIG. 2A shows an incoming call notification image. The incoming call notification image includes an information display portion I, a reception button B1, and a rejection button B2. The information display unit I is an area that indicates that the smartphone 100 has received a voice call, the telephone number of the caller, and the caller name. The listen button B1 is a button operated when the user wants to receive hands-free speech.

When the operation of touching the reception button B1 with a finger or the like is received, the control unit 20 shifts to the hands-free reception state by the function of the incoming call detection module 21a. FIG. 3A is a schematic diagram of a hands-free reception state. As shown in FIG. 3A, in the hands-free listening state, the control unit 20 causes the smartphone 100 to establish a voice call with the calling telephone terminal 200, and uses the microphone 42 and the speaker 43 provided in the vehicle to make a voice call. Make a call.

Specifically, the control unit 20 relays the smartphone 100 and receives the voice data transmitted from the calling telephone terminal 200. Then, the control unit 20 performs signal processing such as decoding and D/A conversion on the received audio data, and outputs it from the speaker 43. Further, the control unit 20 generates voice data by performing signal processing such as A/D conversion and encoding on the voice collected by the microphone 42. Furthermore, the control unit 20 instructs the smartphone 100 to transmit the generated voice data to the calling telephone terminal 200. As a result, the user can talk with the caller without holding the smartphone 100 by the user.

Note that the user can also talk by directly operating the smartphone 100 while the incoming call notification image is displayed. In this case, the control unit 20 shifts to the normal receiving state by the function of the incoming call detection module 21a. FIG. 3B is a schematic diagram of a normal receiving state. As shown in FIG. 3B, in the normal listening state, the smartphone 100 realizes a voice call using a microphone and a speaker provided in the smartphone 100. When the normal reception state is entered, the control unit 20 ends the display of the incoming call notification image by the function of the incoming call detection module 21a and returns to the state of displaying the image (for example, the navigation image) displayed before the incoming call. To do.

On the other hand, in the incoming call notification image of FIG. 2A, when the operation of pressing the reject button B2 for a long time (for example, the contact period is 1 second or more) is accepted, the control unit 20 sends a call to the smartphone 100 by the function of the incoming call detection module 21a. A command for disconnecting communication with the telephone terminal 200 is transmitted. That is, the control unit 20 instructs the smartphone 100 to reject the call with the caller.

In the incoming call notification image of FIG. 2A, when the operation of tapping the reject button B2 (for example, the contact period is less than 1 second) is accepted, the control unit 20 shifts to the response holding state by the function of the response holding module 21b. Hereinafter, the operation of tapping the reject button B2 will be referred to as a response hold operation.

Specifically, by the function of the response holding module 21b, the control unit 20 transmits the response holding voice data 30a to the smartphone 100 and establishes the voice call to establish the response holding voice data when the voice call is received. It is instructed to transmit 30a to the calling telephone terminal 200. For that purpose, first, by the function of the response holding module 21b, the control unit 20 instructs the smartphone 100 to activate the response holding function when a voice call is received. In the present embodiment, the case of receiving a voice call means the case of receiving a voice call and accepting a response holding operation.

When the response holding operation is accepted, the control unit 20 transmits a command to activate the response holding function to the smartphone 100. Here, as shown in FIG. 1, there may be a smartphone 100A having a response holding function and a smartphone 100B having no response holding function. The smartphone 100A having the response holding function records the response holding voice data 130a similar to the response holding voice data 30a recorded by the in-vehicle incoming call system 10. When such a smartphone 100A activates the response holding function, the smartphone 100A establishes a voice call with the calling telephone terminal 200 and transmits the response holding voice data 130a to the calling telephone terminal 200. As a result, the response hold state by the smartphone 100A is realized.

FIG. 3C is a schematic diagram of a response hold state by the smartphone 100A. As shown in the figure, when the smartphone 100A itself transmits the response hold voice data 130a to the calling telephone terminal 200, it is possible to inform the caller that the user of the smartphone 100A cannot receive the call. In this case, the control unit 20 does not transmit the response hold voice data 30a to the smartphone 100 having the response hold function by the function of the response hold module 21b.

When the smartphone 100A having the response holding function receives the command to activate the response holding function from the in-vehicle incoming system 10, the smartphone 100A transmits the response holding voice data 130a to the calling telephone terminal 200 and also notifies that the response holding function is activated. The command is returned to the in-vehicle receiving system 10.

On the other hand, the smartphone 100</b>B that does not have the response holding function does not return the command for notifying that the response holding function is activated to the in-vehicle incoming call system 10. When the control unit 20 transmits the command for activating the response holding function by the function of the response holding module 21b, but does not receive the command for notifying that the response holding function is activated, the smartphone 100B causes the response holding function to be held. It is determined that the function is not provided and the response hold function could not be activated. Specifically, if the command notifying that the response hold function has been activated has not been received even after the predetermined timeout period (for example, 2 seconds) has elapsed from the time when the command to activate the response hold function was sent. In addition, the control unit 20 determines that the smartphone 100B cannot activate the response holding function.

Then, by the function of the response holding module 21b, the control unit 20 holds a response to the smartphone 100B that does not have the response holding function, that is, the smartphone 100B that cannot start the response holding function when receiving the voice call. At the same time as transmitting the voice data 30a, a command is established to establish a voice call and transmit the response hold voice data 30a to the originating telephone terminal 200. As a result, the response hold state by the in-vehicle incoming call system 10 is realized.

FIG. 3D is a schematic diagram of a response hold state by the in-vehicle incoming call system 10. As shown in the figure, the control unit 20 transmits the response hold voice data 30a to the smartphone 100B by the function of the response hold module 21b. Further, by the function of the response holding module 21b, the control unit 20 establishes a voice call with the calling telephone terminal 200 with respect to the smartphone 100B, and transmits a command for transmitting the response holding voice data 30a to the calling telephone terminal 200. By transmitting the response holding voice data 30a to the calling telephone terminal 200 through the smartphone 100B, the response holding voice data 30a is reproduced in the calling telephone terminal 200. As a result, it is possible to notify the caller that the user of the smartphone 100B cannot receive the call.

In addition, when the voice call is received, the control unit 20 touches the image indicating that the response is on hold before determining whether or not the response holding function can be activated by the function of the response holding module 21b. It is displayed on the display 41. Specifically, when the response holding operation is accepted, the control unit 20 immediately displays the response holding image on the touch panel display 41.

In the present embodiment, it is found that the response hold function could not be activated at the stage when the timeout period for waiting for the command notifying that the response hold function was activated has elapsed. The response hold image indicating that the response is being held is displayed on the touch panel display 41 without waiting for the end of the process. That is, the touch panel display 41 displays a response hold image indicating that the response is being held without waiting for the smartphone 100A or the in-vehicle call receiving system 10 to decide which one is to hold the response.

FIG. 2B shows a response hold image. The response hold image includes the information display portion I, the receiving button B1, and the reject button B2. The information display portion I is an area that indicates that the response is on hold, the telephone number of the sender, and the sender name. The listen button B1 is a button operated when the user suspends the response hold and wants to receive hands-free. The reject button B2 is a button operated when the user wants to interrupt the suspension of the response and immediately disconnect the communication with the calling telephone terminal 200.

In the configuration of the present embodiment described above, when the voice call is received, the control unit 20 transmits the response hold voice data 30a to the smartphone 100 and establishes the voice call to set the response hold voice data 30a. Is sent to the calling telephone terminal 200. Accordingly, even if the smartphone 100 does not have the response holding function, the response holding can be performed. That is, the in-vehicle call receiving system 10 can realize the response holding function instead of the smartphone 100.

Here, in the smartphone 100A having the response holding function, the response holding function of the smartphone 100 itself may be activated. Therefore, the control unit 20 can prevent unnecessary communication by not transmitting the response hold voice to the smartphone 100A having the response hold function. In the smartphone 100A having the response holding function, it is only necessary to activate its own response holding function, and therefore it is not necessary to receive the response holding voice data 30a from the in-vehicle incoming call system 10.

In addition, the control unit 20 instructs the smartphone 100 to activate the response holding function when a voice call is received. Then, the control unit 20 transmits the response hold voice data 30a to the smartphone 100B that could not activate the response hold function, establishes a voice call, and transmits the response hold voice data 30a to the originating telephone terminal 200. I decided to order it. As a result, in the smartphone 100B that does not have the response holding function, the in-vehicle call receiving system 10 can realize the response holding function instead of the smartphone 100B.

When a voice call is received, the control unit 20 displays on the touch panel display 41 a response hold image (FIG. 2B) indicating that the response is on hold, before determining whether or not the response hold function has been activated. I decided to display it. Thus, the user can be notified that the response is on hold before it is determined which of the in-vehicle call receiving system 10 and the smartphone 100 implements the response hold function. Whichever of the in-vehicle call receiving system 10 and the smartphone 100 realizes the response holding function, the response holding function can still be realized, so that correct information can be provided to the user early.

(2) Response hold processing:
Next, the response holding process executed by the in-vehicle incoming call system 10 by the function of the in-vehicle incoming call program 21 will be described. FIG. 4 is a flowchart of the response holding process. The response suspension process is a process that is constantly executed while the vehicle in which the smartphone 100 is brought in is traveling.

First, the control unit 20 determines whether an incoming call is detected by the function of the incoming call detection module 21a (step S100). That is, the control unit 20 determines whether or not the smartphone 100 has received a voice call from the calling telephone terminal 200. Specifically, the control unit 20 determines whether or not an incoming call notification command has been received from the smartphone 100.

When it is not determined that the incoming call is detected (step S100: N), the control unit 20 returns to step S100 and waits until the incoming call is detected. On the other hand, when it is determined that the incoming call is detected (step S100: Y), the control unit 20 displays the incoming call notification image by the function of the response holding module 21b (step S110). That is, when the control unit 20 receives the incoming call notification command, the control unit 20 displays the incoming call notification image (FIG. 2A) on the touch panel display 41 and accepts the user's operation on the touch panel display 41.

Next, the control unit 20 determines whether or not there is a response holding operation by the function of the response holding module 21b (step S120). The response hold operation is an operation of tapping the rejection button B2 of the incoming call notification image (for example, the contact period is less than 1 second).

When it is not determined that the response holding operation is performed (step S120: N), the control unit 20 performs an operation other than the response holding by the function of the incoming call detection module 21a (step S125). Specifically, when the operation of touching the receiving button B1 with a finger or the like is received, the control unit 20 shifts to the hands-free receiving state (FIG. 3A). Further, when the operation of pressing the reject button B2 for a long time is accepted, the control unit 20 transmits a command for disconnecting the communication with the calling telephone terminal 200 to the smartphone 100. Furthermore, when an operation of receiving a call on the smartphone 100 is performed while the incoming call notification image is displayed, the control unit 20 shifts to a normal receiving state (FIG. 3B).

On the other hand, when it is determined that the response holding operation is performed (step S120: Y), the control unit 20 instructs the smartphone 100 to activate the response holding function by the function of the response holding module 21b (step S130). That is, although it is unknown at this point whether or not the smartphone 100 has the response holding function, the control unit 20 transmits a command for causing the smartphone 100 to activate the response holding function. The control unit 20 starts the measurement of the timeout period starting from the time when the command for activating the response holding function is transmitted.

Next, the control unit 20 displays the response suspension image by the function of the response suspension module 21b (step S140). That is, the control unit 20 starts displaying the response hold image before the timing (end time of the timeout period) at which it can be determined whether the smartphone 100 has activated the response hold function (FIG. 2B ).

Next, the control unit 20 determines whether the smartphone 100 has activated the response holding function by the function of the response holding module 21b (step S150). Specifically, when the control unit 20 receives from the smartphone 100 a command notifying that the response holding function has been activated, the control unit 20 determines that the smartphone 100 has activated the response holding function. On the other hand, when the command notifying that the response holding function is activated is not received from the smartphone 100 by the end time of the timeout period, the control unit 20 determines that the smartphone 100 cannot activate the response holding function. ..

When it is determined that the smartphone 100 has activated the response holding function (step S150: Y), the control unit 20 ends the response holding process by the function of the response holding module 21b. That is, the control unit 20 entrusts the smartphone 100 with the response hold and waits for the next incoming call (FIG. 3C).

On the other hand, when the smartphone 100 does not determine that the response holding function can be activated (step S150: N), the control unit 20 commands the establishment of the voice call by the function of the response holding module 21b (step S160). That is, the control unit 20 instructs the smartphone 100 to exchange voice data with the calling telephone terminal 200.

Next, the control unit 20 transmits the response hold voice data 30a to the smartphone 100 by the function of the response hold module 21b (step S170). That is, the control unit 20 does not have the response holding function and transmits the response holding voice data 30a to the smartphone 100 that does not hold the response holding voice data 130a.

Next, the control unit 20 uses the function of the response holding module 21b to instruct to send the response holding voice data 30a to the calling telephone terminal 200 (step S180). That is, the control unit 20 transmits a command for transmitting the response hold voice data 30a to the calling telephone terminal 200. By transmitting the response holding voice data 30a to the calling telephone terminal 200, the response holding voice data 30a is reproduced in the calling telephone terminal 200 (FIG. 3D). As a result, it is possible to notify the caller that the user of the smartphone 100B cannot receive the call.

(3) Other embodiments:
In the present invention, the control unit 20 may determine whether or not the smartphone 100 has the response holding function based on the model information of the smartphone 100 by the function of the response holding module 21b. For example, the control unit 20 may acquire the model information of the smartphone 100 at the time of pairing, or may acquire the model information of the smartphone 100 registered by the user in advance. The model information may be information indicating the model of the smartphone 100, information indicating the manufacturer of the smartphone 100, or a program (telephone program, OS, etc.) installed in the smartphone 100. It may be information. By determining whether or not the smartphone 100 has the response holding function based on the model information of the smartphone 100, the response holding function is unnecessarily activated for the smartphone 100 that does not have the response holding function. You can choose not to command.

Even when the smartphone 100 is instructed to start the response holding function to determine whether the smartphone 100 has the response holding function, whether the smartphone 100 can start the response holding function each time there is an incoming call. There is no need to judge whether. For example, the control unit 20 determines whether or not the smartphone 100 has been able to activate the response holding function when the first incoming call is received after performing pairing, and the determination result is paired with the smartphone 100. It may be recorded in association with the ring information. Then, the control unit 20 may instruct activation of the response holding function only to the smartphone 100 in which the fact that it is determined that the response holding function can be activated is recorded. On the other hand, the control unit 20 may transmit the response hold voice data 30a to the smartphone 100 in which it is recorded that the response hold function is not determined to be activated.

In addition, when the voice call is received, the control unit 20 transmits the response hold voice data 30a to the smartphone 100 that does not have the message recording function during the response hold, by the function of the response hold module 21b. A command may be issued to establish a voice call and transmit the response hold voice data 30a to the calling telephone terminal 200, and a message of the caller who responds to the response hold voice may be recorded and recorded in the recording medium 30. In this case, the response hold message output based on the response hold voice data 30a is a message that informs the caller that the user of the smartphone 100 is in a state in which the user cannot receive the call and prompts the caller to leave a message. .. By recording the message of the caller in the recording medium 30, the user can operate the in-vehicle incoming call system 10 at any timing to reproduce the message of the caller.

With the above configuration, the message of the caller can be recorded even if the smartphone 100 does not have the message recording function. Here, the smartphone 100 that does not have the message recording function at the time of holding the response has the response holding function but does not have the message recording function, and has the response holding function and the message recording function. The smartphone 100 that is not included is included. The control unit 20 may record the message of the caller after realizing the response hold state by the in-vehicle incoming call system 10 for the smartphone 100 having neither the response hold function nor the message recording function.

On the other hand, the control unit 20 realizes the response hold state by the in-vehicle incoming call system 10 for the smartphone 100 that has the response holding function but does not have the message recording function, and then further gives the message of the caller. You may record. In this case, even if the smartphone 100 does not have the message recording function, the message of the caller can be recorded. Of course, the control unit 20 may instruct the smartphone 100 having the response holding function but not the message recording function to activate the response holding function of the smartphone 100. In this case, although the message of the caller cannot be recorded, the response holding function unique to the smartphone 100 can be effectively used.

Further, the control unit 20 may realize the response hold state by the in-vehicle incoming call system 10 regardless of whether or not the smartphone 100 has the response hold function. That is, when the user of the smartphone 100 is in the vehicle, the response hold message may be always output based on the response hold voice data 30a recorded by the in-vehicle incoming call system 10. Therefore, the response hold message can also inform the caller that the user of the smartphone 100 cannot listen because the user is in the vehicle (driving).

In the present invention, the on-vehicle incoming call system may be any incoming call system mounted on the vehicle, and may be a part of the vehicle or an on-vehicle device mountable on the vehicle. The mobile phone terminal may be any mobile terminal having a call function, and may be, for example, a mobile phone, a tablet terminal, or a smartphone. The communication unit only needs to be able to communicate with the mobile phone terminal, and may perform wireless communication or wired communication. Receiving a voice call means that the mobile phone terminal receives a voice call request from the caller.

When the mobile phone terminal receives a voice call, the in-vehicle call receiving system accepts selection of acceptance or rejection of the voice call. The in-vehicle call receiving system realizes a function of performing a hands-free call as a basic function when a voice call is selected to be received. The hands-free call is a voice call in which a mobile phone terminal establishes a call and uses a microphone and a speaker included in the vehicle-mounted call receiving system or the vehicle instead of the microphone and the speaker included in the mobile phone terminal.

The incoming call detection unit can detect that the mobile phone terminal has received a voice call via the communication of the communication unit. In addition, the incoming call detection unit may detect that an incoming voice call has been received based on a ringtone or vibration generated by the mobile phone terminal. The response hold voice is a voice that informs the caller that the user of the mobile phone terminal cannot currently make a call, and is a voice generated by the in-vehicle incoming call system. The response hold voice may be a voice preinstalled in the in-vehicle incoming call system or a voice recorded by the user.

When a voice call is received, the response holding unit instructs the mobile phone terminal to establish the voice call. Further, the mobile phone terminal is instructed to transmit the response hold voice to the calling phone terminal. This allows the caller to hear the response hold voice and recognize that the user of the mobile phone terminal cannot currently make a call. The case of receiving a voice call is at least the case of receiving a voice call, and may be the case of receiving a voice call and the user performing a response hold operation. That is, the in-vehicle call receiving system may accept a voice call reception, a response hold, and a refusal selection, or may display a UI image for accepting the selection. The response holding unit may instruct to establish a voice call and transmit the response holding voice to the calling telephone terminal when the response holding selection is received from the user. In addition, the response holding unit instructs to establish a voice call and send the response holding voice to the calling telephone terminal when the operation of selecting to accept or reject the voice call is not accepted for a certain period or longer. Good.

Also, when a voice call is received, the response holding unit transmits the response holding voice to the mobile phone terminal which does not have the response holding function, and establishes the voice call to issue the response holding voice. The terminal may be instructed to transmit, and the response hold voice may not be transmitted to the mobile phone terminal having the response hold function. Here, in the mobile telephone terminal having the response holding function, the response holding function of the mobile telephone terminal itself may be activated. Therefore, it is possible to prevent useless communication by not transmitting the response hold voice to the mobile phone terminal having the response hold function. The mobile phone terminal having the response holding function does not need to receive the response holding voice from the in-vehicle incoming call system, because the response holding function may be activated by itself.

Furthermore, when a voice call is received, the response holding unit instructs the mobile phone terminal to activate the response holding function, and holds the response holding for the mobile telephone terminal that cannot start the response holding function. Along with transmitting the voice, it may be instructed to establish the voice call and transmit the response hold voice to the calling telephone terminal. In the mobile phone terminal having the response hold function, the response hold function of the mobile phone terminal itself can be activated. In a mobile phone terminal that does not have a response holding function, the in-vehicle call receiving system can realize the response holding function instead of the mobile phone terminal.

Further, when the voice call is received, the response holding unit may display an image indicating that the response is held on the display unit before determining whether or not the response holding function can be activated. .. As a result, it is possible to inform the user that the response is on hold before it becomes clear which of the in-vehicle call receiving system and the mobile phone terminal realizes the response hold function. Whichever of the in-vehicle call receiving system and the mobile phone terminal realizes the response holding function, the response holding function can still be realized, so that correct information can be provided to the user at an early stage.

Furthermore, the response holding unit may determine whether or not the mobile phone terminal has a response holding function based on the model information of the mobile phone terminal. As a result, it is possible to prevent the mobile phone terminal that does not have the response holding function from being instructed to unnecessarily activate the response holding function.

In addition, when a voice call is received, the response hold unit sends a response hold voice to a mobile phone terminal that does not have a message recording function at the time of holding a response and establishes a voice call to hold a response. The voice may be instructed to be transmitted to the calling telephone terminal, and the message of the caller responding to the response hold voice may be recorded and recorded in the recording medium. Thus, even if the mobile phone terminal does not have the message recording function, the message of the caller can be recorded. On the other hand, if the mobile phone terminal has the message recording function, the mobile phone terminal may activate the message recording function.

Further, the method in which the in-vehicle call receiving system realizes the response holding function instead of the mobile phone terminal as in the present invention can be applied as a program or a method. Further, the system, program, and method as described above may be realized as a single device, or may be realized by utilizing parts shared with each unit provided in the vehicle, and include various modes. It is a waste. For example, it is possible to provide an in-vehicle incoming call system, an in-vehicle incoming call system, a method, and a program including the above-described devices. Further, it is possible to change as appropriate, such as a part being software and a part being hardware. Further, the invention can be realized as a recording medium of a program for controlling the device. Of course, the recording medium of the software may be a magnetic recording medium or a semiconductor memory, and any recording medium developed in the future can be considered in exactly the same manner.
