The microphone 64 is means for making a call with the destination, and the speaker 66 is means for outputting sound from the destination.

  Next, the operation of the hands-free call system configured as described above will be described.

  First, a route search operation by the navigation device 12 will be briefly described. When the user inputs a departure point, a waypoint, and a destination using the operation unit 36, the route search unit 22 passes from the departure point via the waypoint based on the map information stored in the map information storage unit 24. The optimum guide route to the destination is searched, and the guide route is displayed on the display unit 38 together with the map image. In addition, the current position of the vehicle 10 detected by the current position detection unit 20 is displayed on the display unit 38 together with the guidance route. The user can easily move to the destination according to the displayed information.

  Next, the operation in the case of performing a hands-free call using the navigation device 12 will be described according to the flowchart shown in FIG.

  First, as preparatory work for performing a hands-free call, information on a plurality of mobile phones is registered in the navigation device 12 using the operation unit 36. In this case, when the “setting” button is selected from the menu screen shown in FIG. 7 displayed on the display unit 38, the mobile phone registration list screen shown in FIG. 8 is displayed. The user selects the “details” button from this screen and registers necessary information. As the mobile phone information, for example, as shown in FIG. 5, a registered mobile phone that is a caller terminal, a telephone number, a connection presence / absence indicating whether or not the registered mobile phone is connected to the navigation device 12, a registered mobile phone The telephone number of the mobile phone of the destination terminal set as the discount target for the carrier and registered mobile phone is set. The set information is stored in the mobile phone registration information storage unit 28.

  Next, the address book stored in the address book storage unit 54 of each registered mobile phone is registered in the navigation device 12. In this case, the address book can be transferred from the mobile phones 16a, 16b to the navigation device 12 using the short-range wireless communication unit 34 of the navigation device 12 and the short-range wireless communication unit 58 of the mobile phones 16a, 16b. As the address book information, for example, as shown in FIG. 4, the name of the owner of the mobile phone that is the destination terminal, the telephone number, the group that classifies the owner, and the carrier of the destination terminal are transferred. The The transferred address book information is stored in the address book storage unit 26.

  After the above preparation work is completed, a hands-free call is started.

  When a hands-free call is performed, a hands-free menu screen shown in FIG. 7 is displayed on the display unit 38 of the navigation device 12. Using this screen, the destination mobile phone 14 is set in the navigation device 12 (step S101). After selecting the “Address Book” button from the hands-free menu screen, the user reads the address book from the address book storage unit 26 and displays it on the display unit 38 (see FIG. 4). Select a number.

  When a plurality of mobile phones 16a and 16b are connected to the navigation device 12 (step S102, YES) (in FIG. 8, mobile phones 16a and 16b of “T003” and “P905i” are connected). The telephone selection unit 30 specifies the carrier of the selected destination mobile telephone 14 (step S103). For example, when the destination of name A is selected in FIG. 4, the carrier of the destination is specified as “aaa”.

  Next, the mobile phone selection unit 30 reads the registration information of the mobile phone from the mobile phone registration information storage unit 28, and among the carriers of the source mobile phones 16 a and 16 b connected to the navigation device 12, It is determined whether there are mobile phones 16a and 16b of the same carrier as the carrier. In the example shown in FIG. 5, the carrier of the mobile phone 16a of “T003” is “aaa”, which is the same as the carrier of the call destination. Therefore, the mobile phone selection unit 30 determines that there is a mobile phone 16a having the same carrier “aaa” as the identified destination carrier (step S104, YES). Next, when the destination mobile phone 14 is the mobile phone 14 of the discount target terminal number of the mobile phone 16a stored in the mobile phone registration information storage unit 28 (step S105, YES), for example, a family discount If the mobile phone 14 has a relationship, the mobile phone 16a is selected as the caller terminal (step S106), and the mobile phone 16a and the mobile phone 14 are connected.

  Then, the navigation device 12 performs a hands-free call with the mobile phone 14 using the selected mobile phone 16a. In this case, the user's voice input to the microphone 40 of the navigation device 12 is transmitted as a voice signal from the short-range wireless communication unit 34 to the short-range wireless communication unit 58 of the mobile phone 16a, and then externally transmitted from the call transmission / reception unit 56. Are transmitted to the mobile phone 14. On the other hand, after the voice signal from the mobile phone 14 is received by the call transmitting / receiving unit 56 of the mobile phone 16a, it is transmitted from the short-range wireless communication unit 58 to the short-range wireless communication unit 34 of the navigation device 12, and then the navigation device 12 speakers 42.

  In this case, since the mobile phone 16a and the mobile phone 14 used for the call have the same carrier and are eligible for a discount such as a family discount, a hands-free call can be performed at the lowest price. it can. Note that the call time can also be set as a condition for applying the discount in step S105. For example, if it is a condition that the discount of calls between the same carrier is between 9:00 pm and 5:00 am, the mobile phone 16a is regarded as having a discount only if the current time satisfies this condition. Can be selected as the sender.

  On the other hand, in step S104, if the mobile phone 16a, 16b connected to the navigation device 12 does not have the same carrier as the destination mobile phone 14 (step S104, NO), or even if the carrier is the same, the discount is given. Is not applicable (step S105, NO), the mobile phone 16a, 16b corresponding to the address book corresponding to the selected destination telephone number or the mobile phone 16a, 16b designated by the user is selected. (Step S107). FIG. 9 shows a terminal selection screen displayed on the display unit 38 when the user selects the mobile phones 16a and 16b. Using this screen, the user can select any one of the two mobile phones 16a and 16b connected to the navigation device 12.

  In addition, this invention is not limited to the Example mentioned above, It can change in the range which does not deviate from the summary of this invention. The source mobile phone may be selected so that mobile phones that are eligible for discount provided by the communication carrier, such as discounts for friends and specific groups, are connected.

  For example, as a method of setting the destination in step S101, the “dial” button may be selected from the menu screen shown in FIG. 7 and the telephone number of the destination mobile phone 14 may be directly input. In this case, the carrier of the mobile phone 14 corresponding to the input telephone number can be specified from the address book stored in the address book storage unit 26. Moreover, as a terminal transmission control apparatus, it is not restricted to the navigation apparatus 12 mounted in the vehicle 10, As long as it can communicate with a terminal, various apparatuses including a personal computer are applicable. Furthermore, as a terminal connected to the terminal transmission control device, as long as it communicates with an external terminal, a communication device other than the mobile phones 16a and 16b may be used. It is not limited to two.
