  Subsequently, processing executed by each unit of the vehicle-mounted device 101 according to the embodiment will be described. FIG. 10 is a diagram exemplifying a traveling state notification process according to the embodiment. The process of FIG. 10 may be started when the vehicle-mounted device 101 is activated, for example.

  For example, the driving mode management unit 231 notifies the vehicle information collection unit 232 of a vehicle information collection start request for requesting to collect vehicle information (S1001), and the response indicates that the vehicle information collection has been started. The vehicle information collection start response shown is received (S1002).

  The vehicle information collection unit 232 that has started to collect the vehicle information indicates that the vehicle has started running and the state of the vehicle has changed from stopped to running based on, for example, information about the running of the vehicle acquired from the engine control unit 280. Is detected. Then, the vehicle information collection unit 232 transmits a vehicle information change notification that notifies the traveling mode management unit 231 that the vehicle 100 is traveling (S1011). The change in the state of the vehicle may be detected using, for example, the measured value of the speedometer 281 or the information as to whether or not the side brake is applied.

  When the traveling mode management unit 231 receives the vehicle information change notification indicating that the vehicle 100 is traveling, the traveling mode management unit 231 sets the traveling state information to the traveling mode indicating that the vehicle 100 is traveling, in the telephone application unit 222. And transmits a running state notification instructing (S1012). Upon receiving the traveling state notification, the telephone application unit 222 sets the traveling state information stored in the storage unit 230 to the traveling mode, for example.

  In addition, the vehicle information collecting unit 232 changes the turning indicator of the vehicle from OFF to ON, for example, based on the information indicating the ON (ON) and OFF (OFF) of the turning indicator acquired from the engine control unit 280. Suppose that it is detected. In this case, the vehicle information collection unit 232 transmits a vehicle information change notification indicating that the turn indicator of the vehicle 100 has been turned on to the travel mode management unit 231 (S1021).

  When the traveling mode management unit 231 receives the vehicle information change notification indicating that the turning indicator of the vehicle 100 is turned on, the traveling mode management unit 231 transmits a running state notification indicating that the turning indicator is turned on to the telephone application unit 222. Yes (S1022). Then, the telephone application unit 222 that has received the traveling state notification indicating that the turn indicator is ON indicates, for example, the turn indicator information stored in the storage unit 230, that the turn indicator is ON. Set to information.

  On the other hand, the vehicle information collection unit 232 changes the turning indicator of the vehicle from ON to OFF on the basis of the information indicating the ON (ON) and OFF (OFF) of the turning indicator acquired from the engine control unit 280, for example. Suppose that it is detected. In this case, the vehicle information collection unit 232 transmits a vehicle information change notification indicating that the turn indicator of the vehicle 100 has been turned off to the travel mode management unit 231 (S1031).

  When the traveling mode management unit 231 receives the vehicle information change notification indicating that the turn indicator of the vehicle 100 has been turned off, the traveling mode management unit 231 transmits a running state notification indicating that the turn indicator has been turned off to the telephone application unit 222. Yes (S1032). Then, the telephone application unit 222 that has received the traveling state notification indicating that the turn signal is OFF indicates, for example, the turn signal information stored in the storage unit 230 that the turn signal is OFF. Set to information.

  In addition, the vehicle information collection unit 232, which has started the collection of vehicle information, detects that the state of the vehicle has changed from running to stopped, for example, based on information about running of the vehicle acquired from the engine control unit 280. And In this case, the vehicle information collection unit 232 transmits a vehicle information change notification indicating that the vehicle 100 is stopped to the travel mode management unit 231 (S1041).

  When the traveling mode management unit 231 receives the vehicle information change notification indicating that the vehicle 100 is stopped, the traveling mode management unit 231 transmits a traveling state notification instructing the telephone application unit 222 to cancel the traveling mode (S1042). When the telephone application unit 222 receives the traveling state notification instructing to release the traveling mode, the telephone application unit 222 releases the traveling mode of the traveling state information stored in the storage unit 230, for example.

  Therefore, according to the processing of FIG. 10, the telephone application unit 222 obtains the state of whether the vehicle 100 is running or stopped, the state of whether the turn signal is ON or OFF, and the like. can do.

  FIG. 11 is a diagram exemplifying a process when an incoming call is received according to the embodiment. For example, it is assumed that the mobile terminal 102 connected to the vehicle-mounted device 101 receives an incoming call from the other terminal 103. In this case, an incoming call notification indicating that there is an incoming call is notified to the telephone application unit 222 via the wireless control unit 224 and the HFP/SCO control unit 223 (S1101). The in-vehicle device 101 may be connected to the mobile terminal 102 by short-range wireless communication such as Bluetooth, and communication between the in-vehicle device 101 and the mobile terminal 102 such as notification of an incoming call uses an AT command. May be executed. For example, when the mobile terminal 102 receives an incoming call, the mobile terminal 102 may notify the in-vehicle device 101 of the incoming call by using the +CIEV command. Further, the incoming call notification may include information on the telephone number of the person who made the call.

  Upon receiving the incoming call notification, the telephone application unit 222 returns a response with an ATA command to the mobile terminal 102 via the HFP/SCO control unit 223 and the wireless control unit 224. (S1102). When the mobile terminal 102 receives the ATA command, it receives an incoming call and establishes a call. Further, the telephone application unit 222 transmits, for example, a reproduction instruction for instructing the reproduction control unit 214 to start reproducing the message identified by the message ID of ID1 in the message information 300 (S1103). In the example of the message information 300, the HFP/SCO control unit 223 is designated as the output destination of the fixed message of ID1. In this case, the reproduction control unit 214 reproduces the message of the entry identified by ID1 "I can not respond because it is currently driving. Please give a message after the signal." with the HFP/SCO control unit 223 as the output destination ( S1104). The HFP/SCO control unit 223 reproduces voice using, for example, the Bluetooth (registered trademark) HFP profile and SCO profile, transmits the voice to the mobile terminal 102, and delivers the voice from the mobile terminal 102 to the partner terminal 103. ..

  When the reproduction of the message is completed, the reproduction control unit 214 transmits a reproduction end notification indicating that the reproduction is completed to the telephone application unit 222 (S1105). Upon receiving the reproduction end notification, for example, the telephone application unit 222 instructs the recording control unit 213 to start recording the message (S1106).

  Further, the telephone application unit 222 outputs a simple call switching request to the call switching control unit 211 (S1107). The simple call switching request is, for example, a request for instructing to establish a packet-switching data line with the mobile terminal 102, in addition to the circuit-switching telephone line used for the call. The simple call switching request may include the data of the request data structure 700, for example.

  For example, when the call switching control unit 211 receives the simple call switching request, the call switching control unit 211 transmits a session establishment request message instructing the session control unit 212 to establish a session with the mobile terminal 102 (S1108). The session may be, for example, an SPP session.

  Upon receiving the notification of the session establishment request message, the session control unit 212 sends a message transmission request for requesting the transmission of the Voice Mail session request message to the mobile terminal 102 to the SPP control unit 225 (S1109). Thereby, the SPP control unit 225 transmits the Voice Mail session request message to the mobile terminal 102. The session establishment request message and the Voice Mail session request message may include the data of the request data structure 700, for example.

  Then, the SPP control unit 225 receives a Voice Mail session response message from the mobile terminal 102 via the wireless control unit 224 as a response to the Voice Mail session request message. The SPP control unit 225 transmits a message reception notification including the content of the Voice Mail session response message to the session control unit 212 (S1110). As described above, when the session control unit 212 requests the SPP control unit 225 to send a message such as Voice Mail session request to the mobile terminal 102, in the following description, the message transmission request (Voice Mail session request). Similarly, when the session control unit 212 receives a message such as Voice Mail session response from the mobile terminal 102 via the SPP control unit 225, a message reception notification (Voice Mail session response) will be used in the following description. May be described.

  Upon receiving the message reception notification, the session control unit 212 transmits a session establishment response indicating that the session establishment request to the mobile terminal 102 has been completed, to the call switching control unit 211 (S1111). Upon receiving the session establishment response, the call switching control unit 211 notifies the telephone application unit 222 of the simple call switching response, and notifies that the session for packet communication with the mobile terminal 102 has been requested to be established (S1112). The Voice Mail session response, the session establishment response, and the simple call switching response may include the same information as the response data structure 800, for example.

  If a message message is input from the other party's terminal 103 via the mobile terminal 102 after the recording of the message message is started in S1106, the recording control unit 213 records the input voice in the storage unit 230. (S1113). Then, the telephone application unit 222, for example, notifies the recording control unit 213 of a message stop instruction to stop recording the message message at a predetermined timing, and the recording control unit 213 that has received the message stop instruction stops recording ( S1114). Then, the telephone application unit 222 transmits a reproduction start instruction for instructing reproduction of the fixed message identified by the message ID2 or ID3 to the reproduction control unit 214 (S1115). The reproduction control unit 214 specifies the fixed message 2 or 3 identified by the message ID 2 or ID 3 from the message information 300, reproduces the voice of the message of the specified entry, and outputs it to the output destination HFP/SCO control unit 223. It is output (S1116). If fixed message 2 is played, inquire whether or not a simple call is performed. "I have kept a message. If you want to continue the simple call with voice mail of ○○, if you do not want to continue the number 0, , Please hang up." message may be played. When the reproduction of the message is completed, the reproduction control unit 214 transmits a reproduction end notification indicating that the reproduction is completed to the telephone application unit 222 (S1117).

  As described above, when the control unit 201 of the vehicle-mounted device 101 receives an incoming call notification from the mobile terminal 102, the control unit 201 separates from the mobile terminal 102 a telephone line of the circuit switching system used for a call. , Establish a session on a packet-switched data line for data communication. Therefore, it becomes possible to communicate with the mobile terminal 102 using the data line.

  FIG. 12 is a process executed when, for example, the fixed message 2 is reproduced in S1115 of FIG. 11 and the push sound of pressing the button on the other party's terminal 103 receives information as to whether or not to make a simple call. Is. The fixed message 2 may be, for example, a message asking whether or not a simple call is executed.

  For example, when the call partner presses the number 0 indicating that the simple call is accepted and the push sound of the number 0 is input in the call, the SPP control unit 225 detects that the call partner has accepted the simple call. (S1201). Then, a message reception notification (Voice mail session notification) indicating that the simple call has been accepted is transmitted to the session control unit 212 (S1202).

  It is assumed that the call partner presses the number 0 indicating that the simple call has been accepted and a push sound indicating that the simple call has been accepted is input to the mobile terminal 102. Then, the mobile terminal 102 establishes a session with the vehicle-mounted device 101 and notifies the SPP control unit 225 of a Voice mail session notification message indicating that the session has been established (S1201). Upon receiving the Voice mail session notification message, the SPP control unit 225 transmits a message reception notification including the contents of the Voice mail session notification to the session control unit 212 (S1202).

  The Voice mail session notification may include, for example, information indicating an application that can be used for a simple call with the other terminal 103. For example, the mobile terminal 102 is provided with an application, which is installed in the mobile terminal 102 and is capable of performing a predetermined simple call, based on the telephone number of the partner terminal 103 notified by the message transmission request. It is determined whether or not there is. The mobile terminal 102 uses, for example, a telephone number to make an inquiry to an SNS or the like that provides a service of an application that allows simple calls installed in the mobile terminal 102. Thereby, the mobile terminal 102 may acquire the information as to whether the application is installed on the partner's terminal 103.

  Upon receiving the message reception notification (Voice mail session notification), the session control unit 212 determines an application to be used for the simple call from among the applications available for the simple call notified by the message reception notification. Note that the application may be determined in a predetermined priority order, or may be determined by inquiring the user. The user may be, for example, a driver who drives the vehicle 100 or a passenger. Further, for example, when there is one available application, the application may be determined. Then, the session control unit 212 transmits a session establishment notification including information on the determined application to the call switching control unit 211 (S1203). The session establishment notification may include, for example, the data of the notification data structure 900.

  Upon receiving the session establishment notification, the call switching control unit 211 sends a simple call switching notification to the telephone application unit 222 (S1204). The simple call switching notification may include the data of the notification data structure 900, for example.

  Upon receiving the simple call switching notification, the telephone application unit 222 transmits a reproduction start instruction of the fixed message identified by ID4 to the reproduction control unit 214 (S1205). For example, the reproduction control unit 214 refers to the message information 300, reproduces the voice of the message identified by ID4, and outputs it to the HFP/SCO control unit 223 (S1206). When the reproduction of the message is completed, the reproduction control unit 214 transmits a reproduction end notification indicating that the reproduction is completed to the telephone application unit 222 (S1207). Upon receiving the reproduction end notification, the telephone application unit 222 outputs a disconnection notification requesting the HFP/SCO control unit 223 to disconnect the call (S1208). Upon receiving the disconnection notification, the HFP/SCO control unit 223 outputs a disconnection instruction (for example, an ATH command) to disconnect the call to the mobile terminal 102 (S1209).

  Further, for example, when the information indicating that the simple call has been accepted is not input to the terminal 103 of the other party for a predetermined period, the mobile terminal 102 detects that the simple call has not been accepted, and the voice mail session release The message is transmitted to the vehicle-mounted device 101. Upon receiving the Voice mail session release message (S1211), the SPP control unit 225 sends a message reception notification (Voice mail session release) indicating that the simple call has not been accepted to the session control unit 212 (S1212).

  Upon receiving the message reception notification (Voice mail session release), the session control unit 212 releases the session with the established mobile terminal 102, and the session switching control unit 211 issues a session release notification indicating that the session has been released. (S1213). Upon receiving the session release notification, the call switching control unit 211 transmits to the telephone application unit 222 a simple call switching end message indicating that switching to the simple call has ended (S1214). Upon receiving the simple call switching end message, the telephone application unit 222 outputs a call disconnection notification to the HFP/SCO control unit 223 (S1215). Upon receiving the disconnection notification, the HFP/SCO control unit 223 transmits a disconnection instruction (for example, an ATH command) instructing to disconnect the call to the mobile terminal 102 (S1216). The telephone application unit 222 may wait for the transmission of the disconnection instruction, for example, until the recording of the message is completed in S1114 of FIG.

  According to the processing of FIG. 12 described above, when performing a simple call, the control unit 201 can determine an application to be used in the simple call, notify the other party of the application, and switch to the simple call.

  FIG. 13 is a diagram exemplifying a reproduction process of a recorded message message. For example, it is assumed that the recording control unit 213 records the message message in the storage unit 230 in S1106 to S1114 of FIG. In this case, when the recording control unit 213 finishes recording the message message, the recording control unit 213 confirms whether or not the turn indicator of the vehicle 100 is OFF. Here, when the turn indicator is ON, the recording control unit 213 may wait until the turn indicator is turned OFF. The recording control unit 213 may determine that the turn signal is off, for example, when the turn signal remains off for a predetermined period. When the direction indicator is OFF, the recording control unit 213 sends a message accumulation notification indicating that the message message has been accumulated to the telephone application unit 222 (S1301).

  Upon receiving the message accumulation notification, the telephone application unit 222 transmits a reproduction start instruction of the fixed message identified by ID5 to the reproduction control unit 214 (S1302). For example, the reproduction control unit 214 refers to the message information 300, reproduces the message identified by ID5, and outputs sound from the speaker 260 via the speaker control unit 221 (S1303). The message identified by ID5 may be a voice message indicating that a message has been received and the message message has been stored. When the reproduction of the message ends, the reproduction control unit 214 transmits a reproduction end notification indicating that the reproduction has ended to the telephone application unit 222 (S1304).

  As described above, when the control unit 201 deposits the message message, the control unit 201 can select when the turn signal is in the OFF state and transmit to the user that the message message has been deposited. For example, when the turn indicator is ON, the driver of the vehicle 100 may be driving in a more dangerous situation than when the vehicle is running with the turn indicator OFF. Therefore, driving safety can be improved by selecting when the turn signal is OFF and notifying that the message has been stored.

FIG. 14 is a diagram exemplifying processing when making a telephone call according to the embodiment.
For example, it is assumed that the mobile terminal 102 connected to the vehicle-mounted device 101 makes a call. In this case, a call notification (for example, a +CIEV command) indicating that a call has been sent is notified from the mobile terminal 102 to the telephone application unit 222 via the wireless control unit 224 and the HFP/SCO control unit 223 (S1401). Note that, although FIG. 14 exemplifies a case where the user inputs a call instruction to the mobile terminal 102, for example, the user inputs a call instruction to the vehicle-mounted device 101 and the vehicle-mounted device 101 causes the mobile terminal 102 to perform the call. You may instruct to call. Further, the call notification may include information on the telephone number of the terminal 103 of the other party who has called from the mobile terminal 102.

  If the vehicle 100 is traveling when the call notification is received, the telephone application unit 222 notifies the HFP/SCO control unit 223 of the telephone disconnection notification, and the HFP/SCO control unit 223 notifies the HFP/SCO control unit 223 of the disconnection instruction (for example, The ATH command) is notified to the mobile terminal 102 (S1402). Thereby, the mobile terminal 102 ends the call origination. Here, for example, the driver is driving and is in a situation where it is not desirable to talk, so the telephone is hung up. Further, the telephone application unit 222 outputs, for example, a simple call switching request to the call switching control unit 211 (S1403). It should be noted that the simple call switching request may include the telephone number of the other party's terminal 103, which is the callee, included in the call notification.

  For example, when the call switching control unit 211 receives the simple call switching request, the call switching control unit 211 transmits a session establishment request message instructing the session control unit 212 to establish a session with the mobile terminal 102 (S1404).

  Upon receiving the session establishment request message, the session control unit 212 transmits a message transmission request (Voice Mail session request) to the mobile terminal 102 via the SPP control unit 225 and the wireless control unit 224, and instructs session establishment. Yes (S1405).

  The session control unit 212 receives a message reception notification (Voice mail session response) from the mobile terminal 102 as a response to the message transmission request via the SPP control unit 225 and the wireless control unit 224 (S1406). It should be noted that the Voice mail session response may include information about an application that can be used for a simple call with the terminal 103 of the other party exemplified in the response data configuration 800 described above. Whether or not the mobile terminal 102 has an application installed in the mobile terminal 102 and capable of performing a simple call, using the telephone number of the other terminal 103 notified by the message transmission request, May be determined. For example, the mobile terminal 102 obtains information about whether or not the application for simple call installed in the mobile terminal 102 is installed in the other terminal 103 by inquiring the SNS or the like using the telephone number. You can do it.

  Upon receiving the message reception notification, the session control unit 212 transmits a session establishment response indicating that the mobile terminal 102 has been requested to establish a session, to the call switching control unit 211 (S1407). Subsequently, the call switching control unit 211 notifies the telephone application unit 222 of the simple call switching response (S1408).

  Thereafter, the session control unit 212 receives a message reception notification (Voice mail session notification) indicating that a session has been established with the mobile terminal 102 from the mobile terminal 102 via the SPP control unit 225 (S1409). .. Upon receiving the message reception notification (Voice mail session notification), the session control unit 212 transmits a session establishment notification indicating that the session has been established to the call switching control unit 211 (S1410).

  Upon receiving the session establishment notification, the call switching control unit 211 transmits a simple call switching notification to the telephone application unit 222 to notify that a session has been established with the mobile terminal 102 on the data line (S1411).

  Upon receiving the simple call switching notification, the telephone application unit 222 transmits a reproduction start instruction for instructing reproduction of the fixed message identified by ID6 to the reproduction control unit 214 (S1412). For example, the reproduction control unit 214 refers to the message information 300, reproduces the voice of the message identified by ID6, and outputs it to the speaker control unit 221 (S1413). Since the output destination is the speaker control unit 221, the voice is output from the speaker 260 of the vehicle 100, and the driver can hear the voice. Further, the fixed message 6 may include, for example, an SNS application name used in the simple call, a voice that explains to the user how to make the simple call, and the like. For example, the fixed message 6 is "Since you are running, you can only have simple conversations with voice mail of ○○. For simple conversations, press and hold the PTT (Push To Talk) key and speak. If so, press the END key."

  When the reproduction of the message ends, the reproduction control unit 214 transmits a reproduction end notification indicating that the reproduction has ended to the telephone application unit 222 (S1414). Note that, for example, the message reception notification (Voice mail session response) received in S1406 does not include the information of the application that can be used for the simple call, and the application to be used for the simple call may not be determined. In this case, the fixed message 7 may be reproduced in S1413.

  As described above, the control unit 201 of the vehicle-mounted device 101 can switch from the telephone line to the data line even when the mobile terminal 102 makes a call to the partner's terminal 103 while the vehicle 100 is traveling. ..

FIG. 15 is a diagram illustrating a voice message transmission process according to the embodiment.
For example, when the user sends a voice message to the other terminal 103, the user presses and holds the PPT key provided on the steering wheel of the vehicle 100. Then, a notification indicating that the PPT key has been pressed for a long time is transmitted to the session control unit 212 (S1501). Upon receiving the notification, the session control unit 212 instructs the microphone control unit 226 to turn on the microphone 270. Upon receiving the instruction to turn on the microphone 270, the microphone control unit 226 turns on the microphone 270 and receives a voice input (S1502). On the other hand, the session control unit 212 instructs the recording control unit 213 to start recording audio (S1503).

  Then, the user inputs the message into the microphone 270 by, for example, uttering the message, and the microphone control unit 226 transmits the voice data of the message to the recording control unit 213. The recording control unit 213 records the audio data in the storage unit 230 (S1504).

  Subsequently, when the user releases the depression of the PPT key to complete the input of the voice message, a release notification indicating that the depression of the PPT key is released is input to the session control unit 212 (S1505). Upon receiving the release notification, the session control unit 212 instructs the microphone control unit 226 to turn off the microphone 270. Upon receiving the instruction to turn off the microphone 270, the microphone control unit 226 controls the microphone 270 to turn off and ends the reception of voice input (S1506). In addition, the session control unit 212 transmits a recording stop instruction instructing the recording control unit 213 to stop recording (S1507).

  When the recording control unit 213 receives the recording stop instruction, the recording control unit 213 stops recording and also transmits a voice accumulation notification indicating that voice messages have been accumulated to the session control unit 212 (S1508). Upon receiving the voice accumulation notification, the session control unit 212 issues a message transmission start request (Voice mail send start) for instructing the destination terminal 103 to transmit a voice message to the SPP control unit 225 and the wireless control unit 224. It is transmitted to the mobile terminal 102 via (S1509). Further, the session control unit 212 transmits, for example, a reproduction start instruction for instructing reproduction of the voice message to the reproduction control unit 214 (S1510). Upon receiving the reproduction start instruction, the reproduction control unit 214 transmits the reproduced voice data in the session established with the mobile terminal 102 while reproducing the voice message (S1511), and the voice data is transmitted from the mobile terminal 102. It is sent to the terminal 103 of the other party on the line.

  When the reproduction of the voice message ends, the reproduction control unit 214 transmits a reproduction end notification indicating that the reproduction has ended to the session control unit 212 (S1512). When the session control unit 212 receives the reproduction end notification, the session control unit 212 sends a message transmission request (Voice mail send end) to the SPP control unit 225 and the wireless control unit 224 to notify the end of the transmission of the message addressed to the other terminal 103. It is transmitted to the mobile terminal 102 via (S1513).

  As described above, the user can input a voice message addressed to the other party at a desired timing. Then, the input voice message can be transmitted to the other party using the data line instead of the telephone line. Since the user can input the voice message at a desired timing, it is possible to input the voice message by selecting a timing with a low risk of an accident, for example, according to the driving load of the vehicle 100 during traveling. It is possible.

  Next, the message message reception process will be described. FIG. 16 is a diagram illustrating a message message reception process. For example, when a session has not been established between the mobile terminal 102 and the vehicle-mounted device 101, the mobile terminal 102 sends a voice mail session notification to the vehicle-mounted device 101 upon receiving a message message. When the SPP control unit 225 of the vehicle-mounted device 101 receives the Voice mail session notification from the mobile terminal 102 (S1601), the SPP control unit 225 session-controls the message reception notification (Voice mail session notification) indicating that the mobile terminal 102 has received the message. It transmits to the part 212 (S1602).

  Upon receiving the message reception notification (Voice mail session notification), the session control unit 212 establishes a session with the mobile terminal 102 if the session has not been established. After establishing the session, the session control unit 212 transmits a session establishment notification to the call switching control unit 211 (S1603). Upon receiving the session establishment notification, the call switching control unit 211 transmits a simple call switching notification to the telephone application unit 222 (S1604).

  Further, when the session is established, the SPP control unit 225 receives the notification of Voice mail receive start from the mobile terminal 102 (S1605). Upon receiving the Voice mail receive start, the SPP control unit 225 notifies the session control unit 212 of a message reception notification (Voice mail receive start) and instructs the session control unit 212 to start receiving the message (S1606). In addition, in the processing of S1601 to S1605, the processing in the case where the session has not been established has been exemplified, but for example, when the session has already been established, the processing may start from S1605.

  Upon receiving the message reception notification (Voice mail receive start), the session control unit 212 instructs the recording control unit 213 to start recording the message (S1607). Then, the recording control unit 213 records the voice message transmitted from the partner terminal 103 to the mobile terminal 102 (S1608). The voice message may be notified by voice mail or the like. When the transmission of the message to the vehicle-mounted device 101 is completed, the mobile terminal 102 transmits the notification of Voice mail receive end to the SPP control unit 225. Upon receiving the Voice mail receive end notification, the SPP control unit 225 sends a message reception notification (Voice mail receive end) indicating that the transmission of the message has ended to the session control unit 212 (S1609).

  Upon receiving the message reception notification (Voice mail receive end), the session control unit 212 instructs the recording control unit 213 to stop recording the message (S1610). When the recording control unit 213 receives the instruction to stop recording the message message, the recording control unit 213 stops recording and transmits a storage notification indicating that the message message has been stored to the session control unit 212 (S1611). Upon receiving the storage notification, the session control unit 212 transmits the storage notification to the telephone application unit 222 to notify that the message has been stored (S1612).

  As described above, the vehicle-mounted device 101 can receive the message message from the partner terminal 103 via the data line.

  Next, a message notification accumulation notification process will be described. FIG. 17 is a diagram exemplifying a message accumulation notification process for a user. For example, when the telephone application unit 222 receives the accumulation notification in S1612 described above, after confirming that the turn signal is OFF, it transmits a reproduction start instruction of the fixed message 8 to the reproduction control unit 214 (S1701). .. When the turn indicator is ON, the telephone application unit 222 may wait for the turn indicator to turn OFF and then notify the playback control unit 214 of the playback start instruction of the fixed message 8.

  Upon receiving the reproduction start instruction, the reproduction control unit 214 acquires the message identified by the message ID 8 from the message information 300 and transmits it to the speaker control unit 221 (S1702). The message identified by the notified message ID 8 is output via the speaker 260. The voice of the message identified by the message ID 8 may be, for example, a voice indicating that the message has been received, and may be a voice such as “A message has been received. Would you like to play it?”. Thereby, the vehicle unit 101 can notify the user of the reception of the message.

  When the message notification is completed, the reproduction control unit 214 transmits a message reproduction end notification to the telephone application unit 222 (S1703).

  As described above, upon receiving the message message, the vehicle-mounted device 101 can notify the user that the message message has been received. In addition, by performing the notification while the turn signal is OFF, it is possible to prevent the user from being notified by a voice message in a situation where the user makes a nervous turn, changes lanes, etc., and reduces the risk of an accident. You can

  Next, the message reproduction and completion processing of the simple call will be described. FIG. 18 is a diagram exemplifying message reproduction and completion processing. For example, when the user can listen to the message stored in the vehicle-mounted device 101, the user inputs a message reproduction instruction to the session control unit 212 by short-pressing the PTT key (S1801). Upon receiving the reproduction instruction, the session control unit 212 instructs the reproduction control unit 214 to reproduce the message (S1802).

  The reproduction control unit 214 outputs the message message accumulated in the storage unit 230 from the speaker 260 via the speaker control unit 221 to notify the user (S1803). When all the stored messages have been reproduced, the reproduction control unit 214 displays a message indicating that all the messages have been reproduced, for example, a message such as “The message is over”, and the speaker control unit 221. It is output from the speaker 260 via (S1804). When the reproduction of the message message ends, the reproduction control unit 214 transmits a reproduction end notification to the session control unit (S1805).

  Subsequently, the session control unit 212 instructs the reproduction control unit 214 to reproduce the fixed message 9 identified by ID9 (S1806). The fixed message 9 identified by the instructed ID 9 is displayed by the playback control unit 214 (for example, "For simple conversation, press the PTT and speak. If not necessary, press the END key.") Is output from the speaker 260 via the speaker control unit 221 (S1807). When the reproduction of the message ends, the reproduction control unit 214 transmits a reproduction end notification indicating the end to the session control unit 212 (S1808).

  Here, it is assumed that the user inputs an instruction to end the simple call, for example, by pressing and holding the END key provided on the steering wheel (S1809). Then, the session control unit 212 notifies the SPP control unit 225 of a message transmission request instructing to transmit the voice mail session release to the mobile terminal 102. The SPP control unit 225 sends Voice mail session release to the mobile terminal 102 and disconnects the session (S1810). The Voice mail session release is, for example, a request to instruct the mobile terminal 102 to disconnect the session.

  The session control unit 212 also instructs the reproduction control unit 214 to start reproducing the fixed message identified by ID10 (S1811). Upon receiving the reproduction start instruction, the reproduction control unit 214 causes the speaker 260 to output the fixed message 10 (for example, “end simple call”) for notifying the end of the simple call from the speaker 260 via the speaker control unit 221 (S1812). ). When the reproduction of the message ends, the reproduction control unit 214 transmits a reproduction end notification to the session control unit 212 (S1813). Upon receiving the reproduction end notification, the session control unit 212 transmits a session release notification indicating that the session has been released to the call switching control unit 211 (S1814). Upon receiving the session release notification, the call switching control unit 211 sends a simple call switching end message to the telephone application unit 222 to notify that the switching of the simple call has ended (S1815).

  As described above, the user can listen to the message or end the simple call at a desired timing.

Subsequently, an operation flow relating to the above-mentioned simple call switching will be described.
FIG. 19 is a diagram illustrating an operation flow of a call switching control process executed by the call switching control unit 211. The call switching control unit 211 may start the operation flow of FIG. 19 when the vehicle-mounted device 101 is activated, for example.

  In step S1901, the call switching control unit 211 waits for an event to be detected. For example, when an event such as reception of a message is detected, the flow proceeds to S1902. In step S1902, the call switching control unit 211 reads the notified message, and checks the message read in step S1903. For example, when the message does not include the predetermined information and the message is defective (S1903 is NG), the flow returns to S1901, and the call switching control unit 211 waits for reception of the next event. On the other hand, for example, when there is no defect in the message (S1903 is OK), the flow proceeds to S1904.

  In step S1904, the call switching control unit 211 determines where the sender of the message is. For example, if the message transmission source is the session control unit 212, the flow proceeds to S1905. In step S1905, the call switching control unit 211 confirms the message type. For example, if the message is a session release notification, the flow proceeds to S1906, creates a simple call switching end message, and transmits it to the telephone application unit 222 in S1907.

  If the message is a session establishment response in S1905, the flow advances to S1908 to create a simple call switching response, and transmits it to the telephone application unit 222 in S1907.

  If the message is a session establishment notification in S1905, the flow advances to S1909 to create a simple call switching notification message, and transmits the message to the telephone application unit 222 in S1907.

  If the transmission source of the message is the telephone application unit 222 in S1904, the flow proceeds to S1910. In this case, the call switching control unit 211 determines whether the message includes a telephone number, and when the message does not include the telephone number (NO in S1910), the flow proceeds to S1906. That is, for example, when the telephone number of the terminal 103 of the other party is unknown, the simple call may be terminated. On the other hand, when the message includes the telephone number (there is S1910), the flow proceeds to S1911. In step S1911, the call switching control unit 211 creates a session establishment request message and sends it to the session control unit 212.

  If the transmission source is neither the telephone application unit 222 nor the session control unit 212 in S1904 (S1904 is other), the flow returns to S1901.

  As described above, the call switching control unit 211 generates a message according to the received message and sends the message to the telephone application unit 222 or the session control unit 212.

  FIG. 20 is a diagram illustrating an operation flow of session control processing executed by the session control unit 212. The session control unit 212 may start the operation flow of FIG. 20, for example, when the vehicle-mounted device 101 is activated.

  In step S2001, the session control unit 212 waits for an event to be detected. For example, when an event such as a key operation or a message reception is detected, the flow proceeds to S2002. In step S2002, the session control unit 212 determines the type of detected event. For example, if the detected event is a key operation, the flow proceeds to S2003, the session control unit 212 executes the process 1, and the process returns to S2001. Details of the process 1 will be described with reference to FIG.

  FIG. 21 is a flowchart showing details of the process 1. In step S2101, the session control unit 212 branches the process according to the input key operation. For example, when the input key operation is long pressing of the PTT key, the flow proceeds to S2102. In step S2102, the session control unit 212 creates a voice recording start message instructing the start of voice recording. In step S2103, the session control unit 212 transmits the generated voice recording start message to the recording control unit 213. The recording control unit 213 that has received the notification starts recording. In step S2104, the session control unit 212 turns on the microphone 270 via the microphone control unit 226, and ends the operation flow of process 1. When the process 1 operation flow ends, the flow returns to S2001.

  If the key operation input in S2101 is, for example, the pressing of the PTT key being released, the flow proceeds to S2105. In step S2105, the session control unit 212 turns off the microphone 270 via the microphone control unit 226. In step S2106, the session control unit 212 creates a voice recording stop message instructing to stop voice recording. Then, in step S2111, the session control unit 212 transmits the generated voice recording stop message to the recording control unit 213. The recording control unit 213 that has received the notification stops recording.

  If the key operation input in S2101, for example, is a short press of the PTT key, the flow proceeds to S2107. In step S2107, the session control unit 212 creates a message reproduction start message instructing to start reproduction of the message. Then, the processing proceeds to step S2111, and the session control unit 212 transmits the generated message reproduction start message to the reproduction control unit 214. The reproduction control unit 214 that has received the notification starts reproducing the message.

  If the key operation input in S2101 is, for example, long pressing of the END key, the flow proceeds to S2108. In step S2108, the session control unit 212 creates a reproduction start message instructing reproduction of the fixed message identified by ID10. Then, in step S2109, the session control unit 212 transmits a reproduction start message to the reproduction control unit 214.

  Further, in step S2110, the session control unit 212 creates a Voice mail session release message. Then, in step S2111, the session control unit 212 notifies the SPP control unit 225 of the generated message, and instructs the SPP control unit 225 to disconnect the session with the mobile terminal 102.

  By the processing described in the processing of FIG. 21 above, the user can cause the vehicle-mounted device 101 to execute the processing according to the key operation by inputting the key operation.

  If the event is the message notification in S2002 of FIG. 20 (S2002 is the message notification), the flow proceeds to S2004. In step S2004, the session control unit 212 reads the notified message and checks the message in step S2005. For example, when the message does not include the predetermined information and thus the message is defective (S2005 is NG), the flow returns to S2001, and the session control unit 212 waits for the detection of the next event. On the other hand, for example, when the message includes the predetermined information (S2005 is OK), the flow proceeds to S2006.

  In step S2006, the session control unit 212 confirms the message transmission source. For example, when the transmission source of the message is the reproduction control unit 214 (reproduction control in S2006), the flow proceeds to S2007, the processing of processing 2 described below is executed, and the processing returns to S2001. Details of the process 2 will be described with reference to FIG.

  FIG. 22 is a flowchart showing details of the process 2. In step S2201, the session control unit 212 branches the process according to the input message. For example, when the input message is the voice reproduction end message, the flow proceeds to S2202. In step S2202, the session control unit 212 creates a Voice mail send end message. In step S2203, the session control unit 212 sends the created Voice mail send end message to the SPP control unit 225, the present operation flow ends, and the flow returns to step S2001.

  If the message input in S2201 is the message reproduction end message, the flow proceeds to S2204. In step S2204, the session control unit 212 creates a reproduction start message instructing the reproduction start of the fixed message identified by ID9. In step S2205, the session control unit 212 transmits to the reproduction control unit 214 a reproduction start instruction for the fixed message identified by ID9. In step S2206, the session control unit 212 waits for notification from the reproduction control unit 214 that the reproduction of the fixed message identified by ID9 is completed, and receives the notification. This operation flow ends, and the flow is S2001. Return to.

Then, in step S2405, the session control unit 212 transmits the created session release notification message to the call switching control unit 211.

  If the message is the Voice Mail receive start message in S2401, the flow proceeds to S2406. In step S2406, the session control unit 212 creates a message recording start message. Then, in step S2403, the session control unit 212 transmits the created message recording start message to the recording control unit 213, and instructs the recording control unit 213 to start recording.

  If the message is the Voice Mail receive end message in S2401, the flow proceeds to S2407. In step S2407, the session control unit 212 creates a message recording stop message. Then, in step S2403, the session control unit 212 transmits the created message recording stop message to the recording control unit 213, and instructs the recording control unit 213 to stop recording.

  When the message transmission is completed in S2403, this operation flow ends, and the flow returns to S2001.

  In step S2803, the telephone application unit 222 determines whether or not there is an application that can use voice mail with the partner terminal 103. When there is an application capable of voice mail (S2803 is present), the flow proceeds to S2804. In S2804, the telephone application unit 222 creates a reproduction start message instructing reproduction of the fixed message identified by ID2, and transmits it to the reproduction control unit 214 in S2805. In step S2806, the telephone application unit 222 waits for the reception of the reproduction end message, and upon reception, this operation flow ends, and the flow returns to step S2501.

  If there is no voice mail-enabled application in S2803 (NO in S2805), the flow advances to S2807. In step S2807, the telephone application unit 222 creates a reproduction start message instructing reproduction of the fixed message identified by ID3, and transmits the reproduction start message to the reproduction control unit 214 in step S2808. In step S2809, the telephone application unit 222 waits for the reception of the reproduction end message, and upon reception, this operation flow ends, and the flow returns to step S2501.

  FIG. 29 is a diagram illustrating the details of the process 8. In step S2901, the telephone application unit 222 determines whether a call is being received. If a call is being received (Yes in S2901), the telephone application unit 222 creates a reproduction start message instructing to start reproduction of the fixed message identified by ID4 in S2902, and transmits the reproduction start message to the reproduction control unit 214 in S2903. In step S2904, the telephone application unit 222 waits for reception of the reproduction end message, and when receiving the reproduction end message, creates a disconnection message in step S2905. In step S2906, the telephone application unit 222 transmits the created disconnection message to the HFP/SCO control unit 223, ends the telephone line call, ends the operation flow, and returns the flow to step S2501.

  On the other hand, if there is no incoming call in S2901 (No in S2901), the telephone application unit 222 determines in S2907 whether or not there is an application capable of using voice mail with the partner's terminal 103. If there is an application that can use voice mail (there is S2907), the flow proceeds to S2908. In step S2908, the telephone application unit 222 creates a reproduction start message instructing reproduction of the fixed message identified by ID6, and transmits the reproduction start message to the reproduction control unit 214 in step S2909. In step S2910, the telephone application unit 222 waits for the reception of the reproduction end message, and upon reception, this operation flow ends, and the flow returns to step S2501.

  If there is no application available for voice mail in S2907 (NO in S2907), the flow proceeds to S2911. In S2911, the telephone application unit 222 creates a reproduction start message instructing reproduction of the fixed message identified by ID7, and transmits it to the reproduction control unit 214 in S2912. In step S2913, the telephone application unit 222 waits for the reception of the reproduction end message, and when receiving the reproduction end message, the operation flow ends, and the flow returns to step S2501.

  If the type of the message read in S2503 is a simple call switching end message, the flow proceeds to S2508. In step S2508, the telephone application unit 222 executes processing of processing 9. Details of the process 9 will be described with reference to FIG.

  FIG. 30 is a diagram showing details of the process 9. In step S3001, the telephone application unit 222 creates a disconnection message for disconnecting the session. In step S3002, the telephone application unit 222 transmits a disconnection message to the HFP/SCO control unit 223, this operation flow ends, and the flow returns to step S2501.

  If the type of the message read in S2503 is a message accumulation notification, the flow proceeds to S2509. In step S2509, the telephone application unit 222 executes the process of process 10. Details of the process 10 will be described with reference to FIG.

  FIG. 31 is a diagram showing details of the process 10. In step S3101, the telephone application unit 222 determines whether the turn indicator is ON or OFF. When the turn signal is ON (S3101 is ON), the flow proceeds to S3102, waits for the state of the turn signal to change to OFF, and when the turn signal is turned OFF, the flow returns to S3101. If the direction indicator is OFF in S3101 (S3101 is OFF), the flow proceeds to S3103.

  In step S3103, the telephone application unit 222 determines the type of the input message. For example, in the case where the message is a telephone message input via the telephone line (S3103 is a telephone), the flow proceeds to S3104. In step S3104, the telephone application unit 222 creates a reproduction start message instructing reproduction of the fixed message identified by ID5, and transmits the reproduction start message to the reproduction control unit 214 in step S3105. In S3106, the telephone application unit 222 waits for the reception of the reproduction end message, and upon reception, this operation flow ends, and the flow returns to S2501.

<Example>
Examples of the above-described embodiments will be illustrated below.

[When an incoming call arrives]
FIG. 33 is a diagram for explaining an embodiment when a call is received. It is assumed that the in-vehicle device 101 of the vehicle in which the user is riding and the mobile terminal 102 of the user are connected by the HFP/SPP connection of Bluetooth. Further, it is assumed that vehicle 100 is traveling and is in a traveling mode.

  First, it is assumed that the other party uses the terminal 103 to make a telephone call to the mobile terminal 102 of the user. At this time, the call partner does not recognize that the user is driving.

  Then, the call connection request (SETUP) is received by the user's mobile terminal 102 from the telephone line network (S3301). Upon receiving the call connection request (SETUP), the mobile terminal 102 of the user sends an incoming call notification (+CIEV) to the vehicle-mounted device 101 via the Bluetooth HFP (S3302).

  When the in-vehicle device 101 that has received the incoming call notification is in the traveling mode, it automatically responds (ATA) to the incoming call via the Bluetooth HFP (S3303) and connects to the other terminal 103 (CONNECT) to establish a call state. (S3304). After that, the vehicle-mounted device 101 notifies the terminal 103 of the other party by a voice message that the user cannot respond because the user is driving (S3305), and starts recording the message (S3306).

  At the same time as recording the message, the vehicle-mounted device 101 makes a voice mail session request for a simple call to the mobile terminal 102 via SPP of Bluetooth (S3307). The mobile terminal 102 specifies an application that can be used for a simple call with the terminal 103 of the other party from the applications that can use the simple call, using the telephone number of the other party (S3308). Then, in the session establishment response (Voice mail session response), the in-vehicle device 101 is notified of the application capable of performing a simple call with the partner's terminal 103 via the SPP of Bluetooth (S3309).

  After the recording of the message message, the in-vehicle device 101 notifies that the message message has been stored and informs by voice that the message can be exchanged in the simple call when the application capable of the simple call is determined. (S3310).

  If the other party agrees to use the simple call, press the corresponding dial key. The pressed dial key is notified to the mobile terminal 102 from the telephone line network as DTMF (S3311). Then, the mobile terminal 102 notifies the vehicle-mounted device 101 of a session establishment notification (Voice mail session complete), for example, when the other party accepts the simple call (S3312). On the other hand, when the other party does not approve the simple call (S3314), the mobile terminal 102 notifies the vehicle-mounted device 101 of a session release notification (Voice mail session release) (S3315).

  After the establishment of the simple call session between the in-vehicle device 101 and the mobile terminal 102, the in-vehicle device 101 notifies the other terminal 103 by voice of the simple call application to be used (S3313). Then, the vehicle-mounted device 101 outputs ATH to the portable terminal 102 (S3316) and disconnects the call (S3317). The in-vehicle device 101, when depositing the message from the terminal 103 of the other party of the call, notifies the user that the message is stored (S3318). It should be noted that the notification that the message message is stored may be executed at an appropriate timing according to the driving load of the user, for example, when the turn signal is OFF.

[When making a call]
Next, an example of making a telephone call will be described. FIG. 34 is a diagram for explaining an embodiment when making a call. It is assumed that the in-vehicle device 101 of the vehicle in which the user is riding and the mobile terminal 102 of the user are connected by a Bluetooth HFP/SPP connection. Further, it is assumed that vehicle 100 is traveling and is in a traveling mode.

  For example, it is assumed that the user makes a call from the mobile terminal 102 to the terminal 103 of the other party (S3401). In this case, the mobile terminal 102 transmits a call connection request (SETUP) from the telephone line network to the partner terminal 103 (S3402). Further, the mobile terminal 102 sends a call origination notification (+CIEV) to the vehicle-mounted device 101 via the HFP of Bluetooth (S3403).

  When the in-vehicle device 101 that has received the call notification is in the traveling mode, it outputs ATH to the call notification via the HFP of Bluetooth (S3404), automatically disconnects the phone (S3405), and waits for the mobile phone. Return to receiving state. Note that, as another example, when a calling operation is input to the vehicle-mounted device 101 during the traveling mode, the vehicle-mounted device 101 may suppress the transmission (S3406).

  Then, the vehicle-mounted device 101 makes a session establishment request (Voice mail session request) for a simple call to the mobile terminal 102 via the SPP of Bluetooth (S3407). The mobile terminal 102 determines an application used for voice mail based on the telephone number of the call destination (S3408). The vehicle-mounted device 101 receives a session establishment response (Voice mail session response) from the mobile terminal 102 (S3409). Subsequently, the in-vehicle device 101 is unable to make a call because it is driving and can be used as an alternative means, when the establishment of the session is notified by receiving the session establishment notification (Voice mail session notification) (S3410). The user is notified by voice that there is an application (S3411).

  When the user speaks while pressing the PTT (S3412), the vehicle-mounted device 101 transmits the utterance content to the other party's terminal 103 by a simple call via the mobile terminal 102 (S3413). If a simple call is received via the mobile terminal 102 during the session establishment (S3414), the vehicle-mounted device 101 notifies the user by voice guidance that the simple call is kept (S3415).

[When receiving a message by simple call]
Next, an embodiment at the time of receiving a message in a simple call will be described. FIG. 35 is a diagram for explaining an embodiment when receiving a message in a simple call. It is assumed that the in-vehicle device 101 of the vehicle in which the user is riding and the mobile terminal 102 of the user are connected by the HFP/SPP connection of Bluetooth. Further, it is assumed that vehicle 100 is traveling and is in a traveling mode.

  Then, for example, it is assumed that the mobile terminal 102 receives a voice mail from the terminal 103 of the other party by using an application that can use a simple call (S3501). In this case, for example, if a session with another communication partner is being established between the mobile terminal 102 and the vehicle-mounted device 101, the system waits until a session is available (S3502). Then, for example, when the user presses the END key to input a session disconnection instruction (S3503), the in-vehicle device 101 outputs a Voice mail session release message to the mobile terminal 102 to disconnect the session (S3504). ).

  Subsequently, the mobile terminal 102 determines the application corresponding to the received message as the application to be used for voice mail (S3505). Then, the mobile terminal 102 newly establishes a session with the vehicle-mounted device 101 and notifies the vehicle-mounted device 101 of Voicemail session notification to notify the establishment of the session (S3506). Subsequently, the mobile terminal 102 notifies the vehicle-mounted device 101 of the received message by using the Voice mail receive start message and the Voice mail receive end message (S3507). The in-vehicle device 101 that has kept the message notifies the user by voice guidance that the message has been kept (S3508). When the mobile terminal 102 and the in-vehicle device 101 have not already established a session for a simple call with another terminal 103 when a message is received from the partner terminal 103 in step S3501, the flow proceeds to step S3505. Good.

[When checking a message in a simple call]
FIG. 36 is a diagram illustrating an example of confirmation processing of a message message. The process at the time of confirming the message in FIG. 36 may be performed after the process at the time of receiving the message in the simple call in FIG. 35, for example.

  The user reproduces the accumulated message message by, for example, inputting a reproducing operation into the vehicle-mounted device 101 (S3601). After the message message is reproduced, if the simple call with the partner terminal 103 of the message message is possible, the user is notified by voice that the simple call with the partner terminal 103 is possible (S3602). When transmitting a simple call to the other party of the message, the user speaks while pressing the PTT key (S3603). The uttered voice is temporarily stored in the vehicle-mounted device 101 and is notified to the application used for the simple call via the SPP of Bluetooth (S3604). The application used for the simple call of the mobile terminal 102 transmits the voice from the vehicle-mounted device 101 to the other party via the application (S3605).

  When the mobile terminal 102 receives a simple call (S3606), the simple call application notifies the vehicle-mounted device 101 of the received voice via the SPP of Bluetooth (S3607). The vehicle-mounted device 101 stores the voice from the simple call application as a message message and notifies the user that there is a message message (S3608). After that, in the processes of S3609 and S3610, for example, the same processes as S3601 and S3602 may be executed.

  When the user wants to end the conversation by the simple call, the user presses the END key (S3611). Then, the in-vehicle device 101 sends a voice message to end the simple call (S3612), then transmits a Voicemail session release message to the mobile terminal 102, and ends the session (S3613).

  In addition, FIG. 37 is a diagram illustrating a block configuration of an in-vehicle apparatus 101 according to another embodiment. The in-vehicle device 101 includes, for example, a control unit 201, a storage unit 230, and a communication unit 240. The control unit 201 includes, for example, an output unit 3701, a communication control unit 3702, a storage unit 3703, a reproduction unit 3704, and the like. For example, the control unit 201 operates as the output unit 3701 in S1206 described above. Further, the control unit 201 operates as the communication control unit 3702 in S1509 and S1606 described above, for example. The control unit 201 operates as the storage unit 3703 in S1608 described above, for example. The control unit 201 operates as the reproducing unit 3704 in S1803 described above, for example.

  In the above, some embodiments are illustrated. As described above, according to the embodiment, when an incoming call is received while driving, the call is switched to voicemail communication, so that the user can listen to the voice message or send the voice message at a convenient timing. You can Therefore, it is possible to maintain the conversation with the other party while suppressing the risk of an accident or the like accompanying a call while driving.

  In addition, for example, to reduce the risk of accidents caused by a hands-free call while driving, when an incoming call is received while driving, the in-vehicle device temporarily stores a message and hands-free. It is possible to suppress the function. Then, when the driver wants to respond to the message, the driver's voice can be recorded by the in-vehicle device, the call can be sent back from the in-vehicle device, and when the other party takes a call, the recorded voice can be played back to the other party. Conceivable. However, in such a method, for example, the recorded voice may not be transmitted unless the return call is brought into a call state. Therefore, when the other party does not pick up the call or is out of the service area, the message cannot be transmitted, and work such as retry occurs. Furthermore, when the other party who receives the return message wants to continue talking, he/she calls again, which causes trouble in exchanging the message.

  On the other hand, when a call is sent back from the in-vehicle device and the recorded voice is played when the other party takes a call to convey the message to the other party, when the voice mail function operates on the other party's phone, the voice message of the driver will be accurate. It may not be accumulated. For example, in a center for storing message messages or in an answering machine function of a mobile phone, there is a case where a message message is received after a predetermined message is reproduced, and the timing at which the message is received may not be constant. Alternatively, dial operation may be required when receiving a message. In this case, there is a possibility that the message message may not be accurately stored by the method of reproducing the recorded voice when the other party takes a call. That is, in the method of transmitting a voice message via a telephone line, there is a problem in reliability of message transmission.

  However, according to the above-described embodiment, the message is transmitted not through the telephone line but through the data line of the packet switching system, so that the message can be surely notified even if the other party does not pick up the call.

  Similarly, when making a call while driving, the user can listen to a convenient voice message or send a voice message by switching the communication to voice mail.

  Further, in the above-described embodiment, when a message is stored from the terminal 103 of the other party, the user is notified that the message is stored at a timing when the turn signal of the vehicle 100 is not displayed. Therefore, the user can be prevented from being notified of the voice message in a situation where the user makes a nervous turn or changes lanes, and the risk of an accident can be reduced.

  Therefore, according to the embodiment, it is possible to efficiently maintain a conversation with the other party when making or receiving a telephone call while driving.

  Although the embodiment has been illustrated above, the embodiment is not limited to this. For example, the operation flow described above is an example, and the embodiment is not limited to this. If possible, the operation flow may be executed by changing the order of processing, may include additional processing separately, or may omit some processing.

  FIG. 38 is a diagram exemplifying a hardware configuration of a computer 3800 for realizing the vehicle-mounted device 101 according to the embodiment.
