A model identification unit for identifying a model of each mobile phone searched by the search unit, and an information system of the function of each mobile phone searched by the search unit, which is determined according to the model identified by the model identification unit. A mobile telephone searched by the search means for a mobile telephone to be used for the communication so that a mobile telephone having a higher degree of matching of the function is selected with higher priority according to the degree of matching to the function of the mobile telephone to be used. And selecting means for selecting from the above.

  According to such an information system, a mobile telephone having a high degree of function matching with respect to the function of the mobile telephone used by the information system for communication is preferentially selected from among connectable mobile telephones as a mobile telephone used for communication. Since it is selected, it is possible to prevent the function of the information system from being restricted due to the mismatch between the functions of the mobile telephone used for communication and the information system.

  Here, more specifically, the information system described above corresponds to the function of the mobile phone used for the communication by the information system of the mobile phone function of the model provided in the information system for each mobile phone model. Each of the search means searched for based on the model data of the model identified by the model identification means registered in the model database in the selection means, comprising a model database in which model data representing the degree of matching is registered. You may comprise so that the said information system of the function of a mobile telephone may obtain | require the said matching degree of the function of the mobile telephone used regarding the said communication.

  In this case, the mobile phone selected by the selection unit is used for the model data of the model identified by the identification unit in the information system and for which the model data is not registered in the model database. It is also possible to provide a model database update means for acquiring from a model data server that provides model data of each model of the mobile phone via the existing communication and registering it in the model database.

In addition, the above-mentioned information system is presented to the user with restrictions imposed on communication using the mobile telephone of the information system that occurs when the mobile telephone used for the communication selected by the selection means is used for communication. It is also preferable to provide restriction item presenting means.
In addition, the above information system may be a system mounted in a motor vehicle.

  As described above, according to the present invention, in an information system in which a mobile phone used for communication by short-range wireless communication is connected to the information system, the information system is inconsistent with the information system and the function of the mobile phone used for communication. It is possible to suppress the occurrence of restrictions on the functions.

Embodiments of the present invention will be described below.
In FIG. 1, the structure of the vehicle-mounted system 100 which concerns on this embodiment is shown.
As shown in the figure, the in-vehicle system 100 is wirelessly connected via a wireless PAN (Personal Area Network) using short-range wireless communication such as Bluetooth / IEEE802.15.1 (“Bluetooth” is a registered trademark of The Bluetooth SIG Inc.). A wireless PAN interface 111 that performs wireless communication with a mobile phone 2 that is located at a short distance with a PAN interface, a display device 112, an operation unit 113, a navigation device 114 that includes a GPS receiver 119 and a vehicle sensor 120, and a speaker 121 And a hands-free communication device 115 including a microphone 122, a control unit 116, a memory 117, and a model database 118.

Here, the vehicle sensor 120 is a sensor that detects various traveling states of the vehicle, such as a vehicle speed sensor and an angular velocity sensor.
Next, the contents of the model database 118 of the in-vehicle system 100 are shown in FIG.
As shown in the figure, the model database 118 has entries (each row in the figure) provided corresponding to each model of the mobile telephone 2, and each entry includes a model ID that becomes a management number of the corresponding model. An address range indicating the range of a wireless PAN physical address (BD_ADDR / IEEE802 address, etc.) included in the mobile phone 2 of the corresponding model, a function of the mobile phone 2 of the corresponding model, and a function of the mobile phone 2 used by the in-vehicle system 100 The matching rate representing the degree of matching, the product name of the corresponding model, and the restriction items representing the functions of the in-vehicle system 100 that are restricted when the mobile phone 2 of the corresponding model is used as a use telephone are registered.

  Here, each mobile phone 2 equipped with a wireless PAN interface is fixedly set with a unique wireless PAN physical address before shipment, and the upper bits of the wireless PAN physical address are assigned to the vendor of the latitude telephone. And the model. Therefore, the mobile telephone 2 has a wireless PAN physical address within a unique address range for each model. The model of the mobile phone 2 can be specified from the wireless PAN physical address of the mobile phone 2.

  The matching rate of each model is, for example, -50 points when the data communication service of the mobile phone 2 cannot be used from the in-vehicle system 100, and when the hands-free call service of the mobile phone 2 from the in-vehicle system 100 cannot be used. -70 points, when the ring tone of the mobile phone 2 cannot be controlled from the in-vehicle system 100, a deduction point value such as -10 points is set from 100 points to 0 points according to the function of the mobile phone 2 of the model. It is obtained by deducting the minimum value.

The hands-free call service of the mobile phone 2 is a service that provides a voice communication function via the WAN 3 configured to include a mobile communication network in which the mobile phone 2 is accommodated to an external device connected by a wireless PAN. The data communication service is a service that provides a data communication function via the WAN 3 to an external device connected by a wireless PAN.
Now, returning to FIG. 1, in such an in-vehicle system 100, the control unit 116 is connected to the mobile telephone 2 selected as the telephone to be used via the wireless PAN interface 111, and the data communication service of the connected mobile telephone 2 is connected. Is used to perform data communication via WAN3. Through this data communication, the control unit 116 receives, for example, traffic information from the traffic information center 4 arranged on the WAN 3, and transmits travel information such as the current position and average speed to the traffic information center 4. . Here, in the data communication service, the mobile phone 2 connects to a communication partner via the WAN 3, relays received data received from the communication partner through data communication via the WAN 3, and the in-vehicle system 100. The transmission data input from the terminal is relayed by data communication via the WAN 3 to the communication partner.

  Next, the navigation device 114 is provided with map data, and based on the map data, the current position is calculated from the output of the GPS receiver 119 and the vehicle sensor 120, or the destination to be accepted by the operation unit 113 is recommended. The route is searched with reference to the map data, or a guide image representing the current position, the destination, or the route to the destination is displayed on the display device 112 on the map represented by the map data. Here, the navigation device 114 recommends a route that can reach the destination in the shortest time in consideration of the occurrence of the traffic jam represented by the traffic information acquired by the control unit 116 from the traffic information center 4. Search as a route. In addition, the navigation device 114 also performs processing for displaying the occurrence of traffic congestion represented by these traffic information on the guidance image.

  Next, the hands-free call device 115 is connected to the mobile phone 2 selected as a telephone to be used via the wireless PAN interface 111, and the user uses the hands-free call service of the connected mobile phone 2 so that the user can use the mobile phone 2. A hands-free call, which is a call that is performed without hand-held operation, is executed in response to the user's off-hook operation or the user's call operation for an incoming call to the mobile telephone 2.

  That is, the hands-free call device 115 outputs the voice represented by the received voice signal input from the hands-free call service of the mobile phone 2 via the wireless PAN interface 111 from the speaker 121 during the voice communication of the mobile phone 2, and the microphone 122. A voice signal representing a voice input from the mobile phone 2 is output as a transmission voice signal to the hands-free call service of the mobile telephone 2 via the wireless PAN interface 111. The hands-free call service of the mobile telephone 2 is used to control a call with a communication partner via the WAN 3, to relay a received voice signal received from the communication partner via voice communication via the WAN 3 to the in-vehicle system 100, The transmission voice signal input from the system 100 is relayed to the communication partner by voice communication via the WAN 3.

In such a configuration, the control unit 116 selects a telephone set to be used for data communication of the control unit 116 and a hands-free call of the hands-free call device 115 as described above.
That is, when the power is turned on, the control unit 116 performs a user telephone selection process shown in FIG. 3 to select a user telephone.
As shown in the figure, in this process, an inquiry is first issued from the wireless PAN interface 111 in a broadcast format, and a response of the mobile telephone 2 to the inquiry is detected (step 302). This procedure corresponds to, for example, an inquiry procedure when the wireless PAN is Bluetooth (registered trademark) /IEEE802.15.1.
Then, the mobile telephone 2 that has responded to the inquiry is registered as a connection candidate in the connection candidate list provided in the memory 117 (step 304).

Here, FIG. 2B shows the configuration of the connection candidate list provided in the memory 117 in this way.
As shown in the figure, in the connection candidate list, entries (each row in the figure) corresponding to each connection candidate that is the mobile telephone 2 whose response is detected in step 302 are created. Each entry includes a candidate number that becomes a management number of the corresponding connection candidate, a model ID of the corresponding connection candidate, a wireless PAN physical address of the corresponding connection candidate, whether or not a data communication service is provided, a hands-free call service Presence / absence of provision and priority order are registered.

  In step 304, an entry corresponding to each of the connection candidates of the mobile telephone 2 for which a response is detected in step 302 is created in the connection candidate list, and the created candidate number is associated with the uniquely generated candidate number. The model ID of the connection candidate and the wireless PAN physical address of the corresponding connection candidate are registered. Here, the wireless PAN physical address of the connection candidate is acquired by the response detected in step 302. Further, the model ID is obtained as the model ID of the entry in the model database 118 in which the address range to which the corresponding connection candidate wireless PAN physical address belongs is registered. If there is no entry in the model database 118 to which the address range to which the corresponding connection candidate wireless PAN physical address belongs is registered, unknown is registered as the model ID.

  Next, if each connection candidate is registered in the connection candidate list (step 304), each connection candidate is sequentially called and connected, and the service provided by the connection candidate is identified from the connection candidates (step 306). Here, the procedure for calling and connecting the connection candidate corresponds to the Page procedure when the wireless PAN is Bluetooth (registered trademark) /IEEE802.15.1, for example. The procedure for identifying the service provided by the connection candidate corresponds to a service search procedure using SDP when the wireless PAN is Bluetooth (registered trademark) /IEEE802.15.1, for example.

  Then, when the service provided by the connection candidate is identified (step 306), according to the identification result, the presence / absence of provision of the data communication service of each connection candidate and the presence / absence of provision of the hands-free call service are determined. Registration is made in the connection candidate entry (step 308).

  Further, the matching rate registered in the entry of the model database 118 in which the same model ID as that registered in each connection candidate entry in the connection candidate list is registered, and the smaller the matching rate, the higher the ranking. The priority of each connection candidate is determined so as to be faster. Then, the determined priority order of each connection candidate and the acquired matching rate are registered in each connection candidate entry in the connection candidate list (step 310). However, for connection candidates whose model ID is unknown in the connection candidate list entry, the consistency rate cannot be obtained from the model database 118. Instead, the data communication service registered in the entry is provided. The matching rate calculated according to the presence or absence and the presence or absence of the hands-free call service is used. For example, the matching rate of the connection candidate whose unknown as the model ID is registered in the connection candidate list entry is 20 when both the data communication service and the hands-free call service are provided. This is done by setting the number to 10 when providing only, and 0 when not providing both.

  Next, when the priority order of each connection candidate is registered in this way (step 310), each connection candidate is sequentially assigned to the target telephone according to the priority order registered in the connection candidate list (steps 312, 324, 326). (Step 314), the following processing is performed for each target telephone.

  That is, whether the matching rate of the target phone is less than a predetermined threshold Th (for example, 15), with the matching rate registered in the connection candidate entry as the target phone in the connection candidate list as the matching rate of the target phone If it is less than the threshold value Th, an error message indicating that there is no mobile phone 2 that can be used is displayed on the display device 112 (step 328), and the use phone selection process is terminated.

  On the other hand, if the matching rate of the target telephone is equal to or greater than the threshold Th, an authentication request is transmitted to the target telephone, and a message requesting input of an authentication code to the target telephone is displayed on the display device 112 (step 318). Here, this message is, for example, the mobile phone 2 of the product name of the entry in the model database 118 in which the same model ID as the model ID registered in the connection candidate entry that is the target phone in the connection candidate list is registered. It is a message that prompts the user to enter an authentication code. Then, a timer having a predetermined timeout time is set (step 320), the occurrence of the timer timeout (step 322), and the occurrence of reception of the authentication response from the target telephone (step 330) are monitored.

Here, the mobile telephone 2 that is the target telephone that has received the authentication request prompts the user to input the authentication code of the in-vehicle system 100. If the authentication code is input, the mobile telephone 2 sends an authentication response generated using the authentication code. To the in-vehicle system 100.
If a timeout occurs before receiving an authentication response from the target telephone (step 330) (step 322), the processing for the target telephone is terminated, and the target telephone is the last connection candidate with the highest priority. If this is the case (step 324), an error message indicating that there is no mobile telephone 2 that can be used is displayed on the display device 112 (step 328), and the telephone selection process is terminated. On the other hand, if the target telephone is not the last connection candidate in priority (step 324), the target telephone is switched to the next connection candidate of the target telephone (steps 326, 314), and the process proceeds to step 316. Processing for the target telephone after the switching is started.

  On the other hand, if an authentication response from the target telephone is received before the timer timeout occurs (step 322) (step 330), the authentication response uses the same authentication code as the authentication code registered in the in-vehicle system 100. The mobile phone 2 is authenticated by checking whether it is generated (step 332). Note that the authentication procedure using the authentication request and the authentication response corresponds to the pairing procedure using the PIN when the wireless PAN is Bluetooth (registered trademark) /IEEE802.15.1.

  If authentication fails in step 332, the process for the target telephone is terminated, and if the target telephone is the last connection candidate in the priority order (step 324), there is no mobile telephone 2 that can be used. An error message indicating this is displayed on the display device 112 (step 328), and the telephone selection process is terminated. On the other hand, if the target telephone is not the last connection candidate in priority (step 324), the target telephone is switched to the next connection candidate of the target telephone (steps 326, 314), and the process proceeds to step 316. Processing for the target telephone after the switching is started.

  On the other hand, if the authentication is successful in step 332, the target telephone is set as the use telephone (step 334), and the same model as the model ID registered in the connection candidate list entry of the connection candidate set in the use telephone is set. The restriction items of the entry in the model database 118 in which the ID is registered are displayed on the display device 112 (step 330), and the use telephone selection process is terminated.

In the foregoing, the telephone selection process performed by the control unit 116 of the in-vehicle system 100 has been described.
Here, FIG. 4 shows a processing example of such a telephone selection process.
When the in-vehicle system 100 is turned on, three mobile telephones A, B, and C are brought into the vehicle by a passenger of the vehicle on which the in-vehicle system 100 is mounted. , The mobile phone B is a model whose matching rate with the in-vehicle system 100 is 50, and the mobile phone C is a model whose matching rate with the in-vehicle system 100 is 90.

  In this case, the in-vehicle system 100 that has been turned on starts a telephone selection process and transmits an inquiry in broadcast format (S41). The inquiry is received by each of the mobile telephones A, B, and C, and the mobile telephones A, B, and C respond to the inquiry (S42).

In response to this response, the in-vehicle system 100 recognizes the model of each mobile phone 2 from the wireless PAN physical addresses of the mobile phones A, B, and C, and sequentially calls and connects each mobile phone A, B, The service provided by C is identified (S43, 44, 45).
Then, the in-vehicle system 100 issues an authentication request to the mobile phone A having the highest matching rate obtained from the recognized model (S46), and displays a message M41 on the display device 112 requesting the input of the authentication code to the mobile phone A. The timer is set (T41). At this time, if the user does not input the authentication code to the mobile phone A because the user does not want to use the mobile phone A in the in-vehicle system 100, a timeout (T42) occurs.

If a time-out occurs, the in-vehicle system 100 issues an authentication request to the mobile phone C having the next highest matching rate after the mobile phone A (S47), and displays a message M42 asking for input of the authentication code to the mobile phone A. The information is displayed on the display device 112 and a timer is set (T43).
When the user inputs an authentication code to the mobile phone C (I41), an authentication response is transmitted from the mobile phone C to the in-vehicle system 100 (S48). Upon receiving the authentication response, the in-vehicle system 100 authenticates the mobile phone C using the authentication response (T44), and if the authentication is successful, sets the mobile phone C as a use phone (T45) and restricts the mobile phone C. Items are displayed (M43), and the telephone selection process is terminated.

The processing example of the telephone use selection process has been described above.
As described above, according to the present embodiment, of the connection candidates that are connectable mobile telephones 2, the mobile telephone 2 having a high matching rate with the in-vehicle system 100 is selected as a telephone to be used for communication more preferentially. Therefore, it is possible to prevent the function of the in-vehicle system 100 from being restricted due to the mismatch between the user telephone used for communication and the in-vehicle system 100.

  By the way, the use telephone selection process in the above embodiment is performed when the mobile telephone 2 set as the use telephone at the time of the last power-off is found in step 302 when the power is turned on after a short-time power-off. The mobile telephone 2 may be set as a use telephone unconditionally. Alternatively, the use telephone selection process in the above embodiment is performed when the mobile telephone 2 of the model having the matching rate 100 set in the use telephone at the time of the previous power cut-off is found in step 302. You may make it set to a use telephone unconditionally.

  In the above embodiment, the model data server 5 that provides data similar to the entry contents of the model database 118 shown in FIG. 2A for each model of the mobile telephone 2 may be provided on the WAN 3. . When the control unit 116 of the in-vehicle system 100 completes the telephone selection process, the control unit 116 detects the wireless PAN physical registered at the address of the entry in which unknown is registered in the model ID of the connection candidate list. A model data request with an address is transmitted to the model data server 5 using the data communication service of the user telephone, and the model data received from the model database server 5 is newly stored in the model database 118 as a response to the model data request. Such an entry may be generated and registered. In this case, the model data server 5 transmits the model data in which the address range including the wireless PAN physical address accompanying the model data request is registered to the in-vehicle system 100 as a response to the model data request.

By doing so, the model database 118 of the in-vehicle system 100 can be automatically updated.
Further, the embodiment of the present invention has been described above by taking the application to the in-vehicle system 100 as an example. However, the technology for selecting the mobile telephone 2 to be used shown in the present embodiment is an option for performing communication using the mobile telephone 2. It can be applied to other information systems as well.
