Description

  The present invention relates to an in-vehicle telephone system mounted on a vehicle, an in-vehicle communication device and a mobile phone used in the in-vehicle telephone system.

As a configuration for realizing a voice call in a passenger compartment, for example, there is one shown in Patent Document 1 below.
JP 2002-152840 A

  By the way, in the conventional hands-free system, when a mobile phone receives an incoming call from a carrier network, the mobile phone outputs an incoming call notification signal to the hands-free system. The hands-free system is configured to notify the user. However, in the configuration in which the hands-free system informs the user that the mobile phone is received from the telecommunications carrier network in this way, the presence or absence of the incoming call and the other party are known to the passenger, so the user (driver) There is a problem that it is not possible to properly secure the privacy of the. Further, since the hands-free system and the mobile phone perform wireless communication such as Bluetooth (registered trademark), for example, a voice call by the hands-free system is realized by using the mobile phone as a relay device. There is also a problem that power is consumed.

  The present invention has been made in view of the above-described circumstances, and its purpose is that, when a user makes a voice call using a hands-free system, the presence / absence of an incoming call and an incoming call partner are known to the passenger. It is possible to avoid this problem, to ensure the user's privacy appropriately, to avoid battery power consumption in the mobile phone, and to extend the battery life of the mobile phone. The object is to provide a telephone system, an in-vehicle communication device, and a mobile phone.

  According to the in-vehicle telephone system described in claim 1, when the telecommunications carrier network receives the mobile phone identification information and the in-vehicle communication apparatus identification information from the in-vehicle communication device, the third-party phone is put on hold and carried. Under the premise that the incoming call to the telephone is disconnected and the in-vehicle communication device is re-incoming, the mobile phone notifies the user of the incoming call when the incoming call is received from the carrier network, and then the incoming call transfer request by the user. Is notified to the in-vehicle communication device, and when the in-vehicle communication device is notified of the mobile phone identification information from the mobile phone, the informed mobile phone identification information And when the vehicle-mounted communication device identification information unique to the vehicle-mounted communication device is transmitted to the carrier network, To realize the voice call by free system.

  As a result, when the user instructs an incoming call transfer request after recognizing an incoming call to the mobile phone from the carrier network, the incoming call to the mobile phone from the carrier network is disconnected and re-incoming to the in-vehicle communication device. Since a voice call using the hands-free system will be realized, the hands-free system will not notify the user that the mobile phone has received a call from the carrier network. If the mobile phone itself notifies the user that the mobile phone has received an incoming call from the carrier network, the mobile phone is set to a manner mode in which only the user can be notified of an incoming call from the communication carrier network. Therefore, it is possible to avoid the presence / absence of an incoming call and the fact that the other party is known to the passenger. The seat of privacy can be ensured appropriately.

  In addition, as described above, since the incoming call to the mobile phone from the telecommunications carrier network is disconnected and the incoming call is received again by the in-vehicle communication device, a voice call using a hands-free system is realized using the mobile phone as a relay device. Unlike the conventional ones, the voice call is realized by the hands-free system alone, so that it is possible to avoid the battery power consumption in the mobile phone and the long life of the battery of the mobile phone. Can be achieved.

  In addition, since the mobile phone network will always receive a call from the carrier network first, it is set for the carrier network that the mobile phone or in-vehicle communication device will receive the call first from the carrier network. There is no need to change, and convenience can be improved. Furthermore, since there is no need to change the setting for the communication carrier network in this way, there is an advantage that it is not necessary to consider whether or not the mobile phone is out of service area.

  According to the in-vehicle telephone system described in claim 2, when the mobile phone receives an incoming call display display request from the user after informing the user of the incoming call in response to the incoming call from the communication carrier network, The receiving party telephone number received from the carrier network or the called party information registered in association with the called party telephone number is displayed on the display device. As a result, when the user instructs an incoming call destination display request after recognizing the incoming call to the mobile phone from the communication carrier network, the call destination telephone number received from the communication carrier network is associated with the incoming call destination telephone number. Since the registered called party information is displayed on the display device, it is possible to appropriately notify the user of the called party telephone number or the registered called party information associated with the called party telephone number.

  According to the in-vehicle communication device according to claim 3, when the mobile phone identification information is notified from the mobile phone, the notified mobile phone identification information and the in-vehicle communication device identification information unique to the in-vehicle communication device are communicated. When a call is transmitted to the operator network and re-incoming from the carrier network, a voice call using a hands-free system is realized. Thus, when used together with the mobile phone in the in-vehicle telephone system described in claim 1, the same effects as those described in claim 1 can be obtained. In other words, if the mobile phone is set to a manner mode that can only notify the user of an incoming call from the carrier network, it is possible to avoid the presence or absence of the incoming call and the fact that the other party is known to the passenger. Thus, the user's privacy can be ensured appropriately, battery power consumption in the mobile phone can be avoided, and the battery life of the mobile phone can be extended.

  According to the mobile phone described in claim 4, when an incoming call transfer request is instructed by the user after notifying the user of the incoming call in response to the incoming call from the communication carrier network, the mobile phone unique to the mobile phone The identification information is notified to the in-vehicle communication device. Thereby, by using with the vehicle-mounted communication apparatus in the vehicle-mounted telephone system described in claim 1, the same effect as that described in claim 1 can be obtained. In other words, if the mobile phone is set to a manner mode that can only notify the user of an incoming call from the carrier network, it is possible to avoid the presence or absence of the incoming call and the fact that the other party is known to the passenger. Thus, the user's privacy can be ensured appropriately, battery power consumption in the mobile phone can be avoided, and the battery life of the mobile phone can be extended.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows the overall configuration of the in-vehicle telephone system as a functional block diagram.

  The in-vehicle communication device 3 includes a control unit 13 that controls the overall operation of the in-vehicle communication device 3, a telephone communication unit 14 that performs telephone communication with the communication carrier network 4, and short-range data communication with the mobile phone 2. A short-range data communication unit 15 and an in-vehicle device interface unit 16 are provided. The short-range data communication referred to here is Bluetooth (registered trademark), wireless LAN, or the like. The navigation system 17, the display device 18, the incoming call partner display operation switch 19, the incoming call transfer operation switch 20, and the hands-free system 21 are connected to the in-vehicle device interface unit 16 of the in-vehicle communication device 3 via the in-vehicle LAN 22. Has been.

  The incoming call partner display operation switch 19 and the incoming call transfer operation switch 20 are arranged integrally with the handle so that the user (driver) can easily operate without changing the line of sight during driving. When the operation is performed by the user, an operation notification indicating that the operation is performed by the user is output to the in-vehicle communication device 3 via the in-vehicle LAN 22. The hands-free system 21 includes a microphone 23 for inputting a transmitted voice and a speaker 24 for outputting a received voice. When a voice call instruction is input from the in-vehicle communication device 3, a hands-free voice call is performed. Realize. The telecommunications carrier network 4 is constructed from a mobile communication network or a fixed communication network provided by the telecommunications carrier.

  In this embodiment, the configuration in which the navigation system 17 and the hands-free system 21 are separately provided is described. However, the navigation system 17 in which the hands-free function is incorporated can be substituted for these. May be. In addition, the configuration in which the operation switch 19 for displaying the incoming call partner and the operation switch 20 for transferring the incoming call are integrally provided on the handle is described. The operation switch 20 may be configured to be incorporated in the navigation system 17 or the hands-free system 21.

  Next, the operation of the above configuration will be described with reference to FIGS. Here, FIG. 2 shows the overall processing flow of the in-vehicle phone system 1 as a sequence diagram, FIG. 3 shows the processing performed by the control unit 5 of the mobile phone 2 as a flowchart, and FIG. The process which the control part 13 of the vehicle-mounted communication apparatus 3 performs is shown as a flowchart. Here, a case will be described in which the user gets on the mobile phone 2 that is powered on. Further, in this case, the cellular phone 2 will be described on the assumption that the manner mode in which the vibrator 11 vibrates that a call is received from the communication carrier network 4 is set.

  First, when the user gets on and turns on the ACC switch, driving power is supplied from the in-vehicle battery (not shown) to the hands-free system 21, the operation switches 19 and 20, the display device 18, and the in-vehicle communication device 3. The hands-free system 21, the operation switches 19 and 20, the display device 18, and the in-vehicle communication device 3 are activated. At this time, when the mobile phone 2 is powered on, the short-range data communication unit 12 of the mobile phone 2 and the short-range data communication unit 15 of the in-vehicle communication device 3 establish a wireless link between them. .

  Now, let us consider a case where a third-party mobile phone 25 (a third-party phone in the present invention) transmits the mobile phone 2 as a destination. When a transmission signal is received from the third-party mobile phone 25 when the third-party mobile phone 25 transmits the call from the mobile phone 2, the communication carrier network 4 sends the incoming signal to the mobile phone 2. Is sent to the mobile phone 2.

  In the mobile phone 2, after establishing the wireless link with the in-vehicle communication device 3 (Step S <b> 1), the control unit 5 determines whether an incoming signal is received from the communication carrier network 4 by the telephone communication unit 6. When monitoring is performed (step S2) and it is detected that the incoming signal is received by the telephone communication unit 6 from the telecommunications carrier network 4 ("YES" in step S2), the vibrator 11 is vibrated to thereby create a telecommunications business. The user is notified that the incoming call has arrived from the operator network 4 (step S3).

  When the user recognizes that the mobile phone 2 has received an incoming call from the telecommunications carrier network 4 due to the vibration of the vibrator 11, the user selects whether to request display of the called party. Here, if the user requests display of the called party, the user operates the operation switch 19 for displaying the called party. On the other hand, if the user does not request display of the called party, the called party display is displayed. Therefore, the operation switch 19 is not operated at all. When the operation for requesting the display of the called party is performed by the user, the operation switch 19 for displaying the called party displays an operation notification indicating that the user has performed an operation for requesting the display of the called party via the in-vehicle LAN 22. Output to the in-vehicle communication device 3.

  In the in-vehicle communication device 3, after establishing the wireless link with the mobile phone 2 (Step T <b> 1), the control unit 13 receives an operation notification from the operation switch 19 for displaying the called party via the in-vehicle LAN 22. It is monitored whether or not it has been input to the unit 16 (step T2), and it is detected that an operation notification is input from the operation switch 19 for displaying the incoming call partner to the in-vehicle device interface unit 16 via the in-vehicle LAN 22 (step S2). “YES” at T2), the input operation notification is transmitted from the short-range data communication unit 15 to the mobile phone 2 (step T3).

  In the cellular phone 2, when the control unit 5 detects that the operation notification is received from the in-vehicle communication device 3 by the short-range data communication unit 12 (“YES” in step S <b> 4), the control unit 5 displays the display instruction. 12 is transmitted to the in-vehicle communication device 3 (step S5). At this time, the control unit 5 also causes the near-field data communication unit 12 to transmit the incoming party telephone number received from the communication carrier network 4 to the in-vehicle communication device 3.

  In the in-vehicle communication device 3, when the control unit 13 detects that the display instruction and the receiving party telephone number are received from the mobile phone 2 by the short-range data communication unit 15 ("YES" in step T4), the control unit 13 receives the received instruction. The display instruction and the called party telephone number are output from the in-vehicle device interface unit 16 to the display device 18 via the in-vehicle LAN 22 (step T5), and as shown in FIG. 5A, the called party telephone number (090 × Xxxxxxx) is displayed on the display device 18. In this case, if personal information or the like (the called party information referred to in the present invention) is registered in the mobile phone 2 in association with the telephone number, the individual registered in association with the called party telephone number Information or the like may be displayed on the display device 18.

  Next, when the user recognizes the called party by displaying the called party telephone number on the display device 18, the user selects whether or not to request the transfer of the received call. Here, if the user requests transfer of incoming calls, the user operates the operation switch 20 for incoming calls. On the other hand, if the user does not request transfer of incoming calls, the user operates the operation switch for incoming calls. 20 is not operated at all. When an operation for requesting transfer of incoming calls is performed by the user, the operation switch 20 for incoming calls transfers an operation notification indicating that an operation for requesting transfer of incoming calls has been performed by the user via the in-vehicle LAN 22. Output to 3.

  In the in-vehicle communication device 3, when the control unit 13 detects that the operation notification is input from the operation switch 20 for incoming call transfer to the in-vehicle device interface unit 16 via the in-vehicle LAN 22 ("YES" in step T6), A user identification information request is transmitted from the short-range data communication unit 15 to the mobile phone 2 (step T7). At this time, as shown in FIG. 5B, the control unit 13 is referred to as “during transfer” indicating that an incoming call from the communication carrier network 4 is being transferred from the mobile phone 2 to the in-vehicle communication device 3. The guidance is displayed on the display device 18.

  In the cellular phone 2, when the control unit 5 detects that the user identification information request is received from the in-vehicle communication device 3 by the short-range data communication unit 12 ("YES" in step S6), it is uniquely given to itself. User identification information (cellular phone identification information as used in the present invention) is transmitted from the short-range data communication unit 12 to the in-vehicle communication device 3 (step S7). In this case, the user identification information is information necessary for the communication carrier network 4 to identify the mobile phone 2, for example, a telephone number uniquely assigned to the mobile phone 2.

  In the in-vehicle communication device 3, when the control unit 13 detects that the user identification information is received from the mobile phone 2 by the short-range data communication unit 15 ("YES" in step T8), the received user identification information And the vehicle-mounted communication device identification information uniquely assigned to itself are transmitted from the telephone communication unit 14 to the communication carrier network 4 (step T9). In this case, the in-vehicle communication device identification information is information necessary for the mobile operator network 4 to identify the in-vehicle communication device 3, for example, a telephone number uniquely assigned to the in-vehicle communication device 3.

  When the user identification information and the in-vehicle communication device identification information are received from the in-vehicle communication device 3, the telecommunications carrier network 4 places the third-party mobile phone 25 on hold and transmits an incoming call disconnect signal to the mobile phone 2. At the same time, a re-incoming signal is transmitted to the in-vehicle communication device 3.

  In the cellular phone 2, when the control unit 5 detects that the incoming call disconnect signal is received by the telephone communication unit 4 from the communication carrier network 4 (“YES” in step S <b> 8), the control unit 5 receives the incoming call from the communication carrier network 4. Is cut (step S9). On the other hand, in the in-vehicle communication device 3, when the control unit 13 detects that the re-incoming signal is received from the communication carrier network 4 by the telephone communication unit 14 ("YES" in step T10), the in-vehicle device interface unit 16 A voice call by the hands-free system 21 is realized by outputting a voice call instruction to the hands-free system 21 (step T11). At this time, as shown in FIG. 5C, the control unit 13 causes the display device 18 to display a guidance “calling” indicating that a voice call by the hands-free system 21 is realized.

  Through the series of processes described above, the user can transfer an incoming call from the telecommunications carrier network 4 to the mobile phone 2 from the mobile phone 2 to the in-vehicle communication device 3, thereby realizing a voice call by the hands-free system 21. can do.

  By the way, although the case where the third party's telephone is a mobile telephone has been described above, the same processing is performed when the third party's telephone is a fixed telephone. Further, in the present embodiment, the user operates the incoming call transfer operation switch 20 after the user operates the incoming call partner display operation switch 19, so that after the user recognizes the incoming call partner, the mobile phone from the communication carrier network 4. The case where the incoming call to 2 is transferred from the mobile phone 2 to the in-vehicle communication device 3 is explained, but the user operates the operation switch 20 for incoming call transfer without operating the operation switch 19 for displaying the other party. By doing so, the incoming call from the communication carrier network 4 to the mobile phone 2 may be transferred from the mobile phone 2 to the in-vehicle communication device 3 without the user recognizing the called party.

  As described above, according to the present embodiment, when the carrier network 4 receives the user identification information and the in-vehicle communication device identification information from the in-vehicle communication device 3, the third-party mobile phone 25 is put on hold. The mobile phone 2 notifies the user of the incoming call when the incoming call is received from the communication carrier network 4 under the premise that the incoming call to the mobile phone 2 is disconnected and the in-vehicle communication device 3 receives the incoming call again. Then, when an incoming call transfer request is instructed by the user, user identification information unique to the mobile phone 2 is notified to the in-vehicle communication device 3, and the in-vehicle communication device 3 is notified of the user identification information from the mobile phone 2. Then, the notified user identification information and in-vehicle communication device identification information unique to the in-vehicle communication device 3 are transmitted to the communication carrier network 4 and re-incoming from the communication carrier network 4 Once, it constituted by the hands-free system 21 so as to realize a voice call.

  Accordingly, when the user instructs an incoming call transfer request after recognizing the incoming call to the mobile phone 2 from the telecommunications carrier network 4, the incoming call to the mobile phone 2 from the telecommunications carrier network 4 is disconnected and the in-vehicle communication device 3, the voice call by the hands-free system 21 is realized, so that the hands-free system 21 does not notify the user that the mobile phone 2 has received the call from the communication carrier network 4, When the mobile phone 2 itself is set to the manner mode by notifying the user that the mobile phone 2 has received the call from the communication carrier network 4, the presence / absence of the incoming call and the other party are notified to the passenger. It is possible to avoid being known in advance, and it is possible to appropriately ensure the privacy of the user.

  Further, as described above, since the incoming call to the mobile phone 2 from the telecommunications carrier network 4 is disconnected and re-received to the in-vehicle communication device 3, the hands-free system 21 uses the mobile phone 2 as a relay device. The voice call is never realized, and the voice call is realized by the hands-free system 21 alone, so that the battery power consumption in the mobile phone 2 can be avoided and the battery life of the mobile phone 2 is long. Can be achieved.

  In addition, since the mobile phone 2 is always received from the telecommunications carrier network 4 first, the telecommunications carrier determines which of the mobile phone 2 and the in-vehicle communication device 3 is to receive the call first from the telecommunications carrier network 4. It is not necessary to change the setting for the network 4, and convenience can be improved. In addition, since it is not necessary to change the setting for the communication carrier network 4 in this way, there is an advantage that it is not necessary to consider whether the mobile phone 2 is out of service area.

  Furthermore, the mobile phone 2 notifies the user of the incoming call when the incoming call is received from the telecommunications carrier network 4, and when an incoming call destination display request is instructed by the user, the incoming call received from the telecommunications carrier network 4 is received. The display device 18 is configured to display the other party telephone number or personal information registered in association with the called party telephone number. Thus, when the user instructs an incoming call partner display request after recognizing the incoming call to the mobile phone 2 from the communication carrier network 4, the incoming call destination telephone number received from the communication carrier network 4 or the incoming call destination telephone number is displayed. Since personal information and the like registered in association with each other are displayed on the display device 18, the user is appropriately informed of the called party telephone number or the personal information registered in association with the called party telephone number. be able to.

The present invention is not limited to the above-described embodiment, and can be modified or expanded as follows.
The in-vehicle communication device 3 may be in the form of a module as an in-vehicle communication module.
The operation switch 19 for displaying an incoming call partner and the operation switch 20 for transferring an incoming call are not limited to being arranged separately, and they may be composed of the same switch. Thus, a configuration may be used in which the operation for displaying the incoming call partner is distinguished from the operation for transferring the incoming call.

  Immediately after the in-vehicle communication device 3 is activated, the short-range data communication unit 12 of the mobile phone 2 and the short-range data communication unit 15 of the in-vehicle communication device 3 are not limited to the configuration in which a wireless link is established between them. Immediately after the operation notification is output to the in-vehicle communication device 3 from the operation switch 19 for incoming call or the operation switch 20 for call transfer, the short-range data communication unit 15 of the mobile phone 2 and the short-range data communication unit 15 of the in-vehicle communication device 3 May be configured to establish a wireless link between them.
