  Here, for example, the connection determination unit 101 may obtain the name of the user of the mobile phone 20 from each of the mobile phones 20a to 20d. For example, the connection determination unit 101 may acquire the incoming call information by indicating the user name in the incoming call information. The name of the user of the caller telephone set is acquired from, for example, the entry of the telephone number indicated by the incoming call information in the phone book information stored in the phone book DB 104 for each user. Further, for example, by storing the phone book information of the mobile phones 20a to 20d in the user-specific phone book DB 104 in association with the names of the users of the mobile phones 20a to 20d, the user of the mobile phone 20 The phone book information of the mobile phone 20 related to the incoming call may be specified from the name of the user and used. The telephone number of the caller telephone can be obtained from the incoming call information. In addition, as long as it is information specifying the user of the mobile phone 20, other information (for example, a user ID) may be used instead of the user name.

  Here, the mobile phone 20 may also make a call. Specifically, the connection control unit 201 displays an arbitrary incoming call on the display unit 208 and outputs a ring tone from the speaker 206.

  When the user presses the call button displayed on the touch panel, the input unit 109 outputs input information indicating that the call button has been pressed to the connection determination unit 101. A physical operation button may be used as the call button.

  In response to the output of the input information from the input unit 109, the connection determination unit 101 displays the caller telephone number indicated by the incoming call information output from the mobile terminal connection unit 102 as the common telephone number stored in the common telephone number DB 105. A search is made from the common telephone number indicated by the information (S3). That is, the connection determination unit 101 determines whether or not the caller telephone number is present in the common telephone number indicated by the common telephone number information. This determination may be made in advance at the timing when the incoming call information is received.

  When it is determined that the caller's phone number is present in the common phone number indicated by the common phone number information (S4: Yes), the connection determination unit 101 provides connection status notification information for notifying that the hands-free connection by the car navigation system 10 is performed. It outputs to the portable terminal connection part 102 (S5).

  When it is determined that the source telephone number does not exist in the common telephone number indicated by the common telephone number information (S4: No), the connection determination unit 101 performs normal connection (does not perform hands-free connection by the car navigation system 10). Is output to the mobile terminal connection unit 102 (S6).

  The mobile terminal connection unit 102 transmits the connection status notification information output from the connection determination unit 101 to the mobile phone 20. That is, the mobile terminal connection unit 102 notifies the mobile phone of the connection status (S7). The car navigation connection unit 202 of the mobile phone 20 outputs the connection status notification information transmitted from the car navigation 10 to the connection control unit 201.

  The connection control unit 201 starts a call according to the content indicated by the connection status notification information output from the car navigation connection unit 202 (S8). When the connection status notification information indicates a hands-free connection by the car navigation system 10, a call using the speaker 106 and the microphone 107 of the car navigation system 10 is started. That is, the central control unit 200 transmits call control information responding to an incoming call to the source telephone via the base station connection unit 203 and establishes a line with the source telephone. Then, the central control unit 200 starts transferring voice information in a call between the car navigation 10 and the caller telephone.

  Specifically, the central control unit 200 transmits voice information received from the caller telephone set via the base station connection unit 203 to the car navigation system 10 via the car navigation connection unit 202. The central control unit 100 of the car navigation system 10 outputs voice information received from the mobile phone 20 via the mobile terminal connection unit 102 to the speaker 106. The speaker 106 outputs the sound indicated by the sound information output from the central control unit 100. As a result, the passenger of the vehicle can hear the voice of the user of the caller telephone. In addition, the microphone 107 generates voice information indicating the voice of the passenger on the vehicle and outputs the voice information to the central control unit 100. The central control unit 100 transmits the audio information output from the microphone 107 to the mobile phone 20 via the mobile terminal connection unit 102. The central control unit 200 of the mobile phone 20 transmits the voice information received from the car navigation system 10 via the car navigation connection unit 202 to the caller telephone set via the base station connection unit 203. Thus, the caller's telephone outputs the voice of the vehicle occupant based on the voice information, so that the user of the caller's telephone can hear the voice of the vehicle occupant. According to this, all the passengers of the vehicle can share the conversation in the call with the user who is the caller.

  On the other hand, when the connection status notification information indicates a normal connection, a call is started using the mobile phone 20 without using the speaker 106 and the microphone 107 of the car navigation 10. That is, the central control unit 200 transmits call control information responding to an incoming call to the source telephone via the base station connection unit 203 and establishes a line with the source telephone. The central control unit 200 transmits / receives voice information in a call to / from a caller telephone.

  Specifically, the central control unit 200 outputs audio information received from the mobile phone 20 via the mobile terminal connection unit 102 to the speaker 206. The speaker 206 outputs the sound indicated by the sound information output from the central control unit 200. As a result, the user of the mobile phone 20 can hear the voice of the user of the caller telephone set. In addition, the microphone 207 generates voice information indicating the voice of the user of the mobile phone 20 and outputs it to the central control unit 200. Central control unit 200 transmits the audio information output from microphone 207 to the caller telephone set via base station connection unit 203. According to this, only the user of the mobile phone 20 that has received the call can make a call with the user of the caller. Furthermore, at this time, when the mobile phone 20 is connected to a headset (not shown), voice information in a call may be transferred between the mobile phone 20 and the headset. According to this, even if the user of the mobile phone 20 is a driver of the vehicle, it is possible to talk with the caller user in a hands-free manner by wearing the headset.

  Here, in the above description, the case where the same call is performed whether or not the caller's phone number is present in the common phone number indicated by the common phone number information is exemplified, but it is different in each case. You may make it call. For example, when the caller's phone number does not exist in the common phone number indicated by the common phone number information, the connection determination unit 101 of the car navigation 10 does not display the call button and does not display the call button as shown in FIG. 6B. Only notification may be performed.

  When the call button is pressed on the mobile phone 20, the connection control unit 201 of the mobile phone 20 starts a call using the mobile phone 20 in response to the output of input information from the input unit 209. May be. All passengers in the vehicle are allowed to talk on the mobile phone 20 to passengers who can hold the mobile phone 20 and talk independently, such as passengers other than the driver of the vehicle. It is because it may do.
