No. 2003-198713

  Consider a technique that requires a selection and authentication work for establishing a wireless connection as described above to be used by a company that operates a plurality of vehicles. In such a trader, the combination of which crew member gets into which vehicle may not be fixed. In addition, the combination of which mobile radio communication terminal is owned by which crew member may not be fixed.

  Therefore, when the occupant gets into the vehicle, the occupant checks each time the portable terminal that he / she currently has, selects the portable terminal manually by operating the fixed installation device, The authentication code corresponding to the fixed installation device mounted on the vehicle must be confirmed each time, and the authentication code must be manually input. It is a heavy burden on the crew to perform such work every time the vehicle enters the vehicle. However, it is not preferable in terms of security to always allow unlimited wireless connection even if the burden is large.

  In view of the above points, the present invention improves the technology that requires selection and authentication work for establishing a wireless connection between an in-vehicle fixed installation device and a portable wireless communication terminal, while maintaining security to some extent. An object is to reduce the work burden on the user.

  The feature of the present invention for achieving the above object is that it is fixed to each of a plurality of vehicles and permits wireless connection with a wireless communication device that is the transmission source of the authentication code if the authentication code is proper for itself. A fixed installation device (3) forbidden if it is not authorized, and a plurality of portable devices capable of being carried by a plurality of crew members of the plurality of vehicles and wirelessly connected to the plurality of fixed installation devices. The present invention relates to a vehicle information communication system including a wireless communication terminal (2).

  In the first feature of the present invention, each of the plurality of fixed installation devices and the plurality of portable wireless communication terminals includes the plurality of portable wireless communication terminals, the plurality of crew members, and the plurality of the plurality of portable wireless communication terminals in a plurality of time zones. The connection schedule data (12a) indicating the combination of the fixed installation device and the plurality of regular authentication codes is recorded.

  Each of the plurality of portable wireless communication terminals records the identification information of the crew member input by the crew member carrying the portable wireless communication terminal among the plurality of crew members. As a result, information on which occupant currently has the portable wireless communication terminal is recorded in each of the portable wireless communication terminals.

  When a connection request is transmitted from one of the plurality of portable wireless communication terminals (hereinafter referred to as portable wireless communication terminal X) to one of the fixed installation devices (hereinafter referred to as fixed installation device Y), The fixed installation device Y determines the portable wireless communication terminal to be connected to itself by applying the current date and time and the identification information of the fixed installation device Y to the connection schedule data recorded by itself. Further, if the portable wireless communication terminal X is the portable wireless communication terminal to be connected, the portable wireless communication terminal X is requested to receive an authentication code, and the portable wireless communication terminal X is to be connected to the portable wireless communication terminal X. If it is not a wireless communication terminal, the portable wireless communication terminal X is not requested for an authentication code.

  In this way, when there is a connection request, the fixed installation device Y is authenticated if the transmission source of the connection request is currently a portable wireless communication terminal that should be connected to itself in light of the connection schedule data. Request code, otherwise don't request authentication code. By such an operation of the fixed installation device Y, a wireless connection partner of the fixed installation device Y is automatically selected. Therefore, it is not necessary for the crew to operate the fixed installation device and select the portable wireless communication terminal of the wireless connection partner, and as a result, the work load on the crew is reduced.

  In addition, the portable wireless communication terminal X records the current date and time and the crew identification information recorded by itself based on the request for the authentication code from the fixed installation device Y. By applying to the connection schedule data, the authentication code that is legitimate for the fixed installation device to be connected by itself is determined, and the determined authentication code is transmitted to the fixed installation device Y.

  Then, based on the reception of the authentication code transmitted from the mobile wireless communication terminal X, the fixed installation device Y permits the mobile wireless communication terminal X to establish a wireless connection with itself.

  As described above, when the portable wireless communication terminal X receives the request for the authentication code, the mobile wireless communication terminal X determines the normal authentication code for the fixed installation device to be connected by referring to the connection schedule data. Accordingly, the authentication code is automatically input to the fixed installation device Y, so that the crew does not need to manually input the authentication code. As a result, the work load on the crew is reduced.

  The vehicular information communication system includes an operation management center (1) that transmits the connection schedule data to the plurality of portable wireless communication terminals, and one of the plurality of portable wireless communication terminals (portable wireless communication terminal P). May receive and record the connection schedule data transmitted from the operation management center, and pass the received connection schedule data to the fixed installation device Y.

  However, in order to realize the transfer of connection schedule data from the portable wireless communication terminal to the fixed installation device, it is necessary to establish a wireless connection between the portable wireless communication terminal and the fixed installation device Y, In order to establish a wireless connection by the above procedure, a contradiction arises that the fixed installation device Y must have connection schedule data.

  As a mechanism for resolving this contradiction, the mobile radio communication terminal P transmits the received connection schedule data and a common authentication code that is valid for all of the plurality of fixed installation devices to the fixed installation device Y, and The installed device Y releases the prohibition of wireless connection with the portable wireless communication terminal P based on the reception of the common authentication code, and receives the schedule data transmitted from the portable wireless communication terminal P. It may be recorded.

  As described above, the connection from the portable wireless communication terminal to the fixed installation device Y can be achieved by using the common authentication code that is legitimate for any of the plurality of fixed installation devices exceptionally for the delivery of connection schedule data. Deliver schedule data. The portable wireless communication terminal P may be the same as or different from the portable wireless communication terminal X.

  In addition, the second feature of the present invention is different from the first feature in that the mobile wireless communication terminal X uses the connection schedule data in order to determine a proper authentication code for the fixed installation device Y to be connected. The identification information of the portable radio communication terminal X is applied instead of the identification information of the crew member who records it. The connection schedule data indicates combinations of the plurality of portable wireless communication terminals, the plurality of fixed installation devices, and a plurality of regular authentication codes in a plurality of time zones. By referring to the connection schedule data, the wireless communication terminal X can determine a proper authentication code for the fixed installation device to which it is to connect.

  In this case, it is not essential to include crew information in the connection schedule data. In addition, it is not essential for each of the plurality of portable wireless communication terminals to record the identification information of the crew member input by the crew member carrying the portable wireless communication terminal among the plurality of crew members.

  Note that the first feature and the second feature of the present invention can also be realized as a method of establishing a wireless connection including the operation steps in the vehicle information communication system.

  In addition, the code | symbol in the parenthesis in the said claim shows the correspondence of the term described in the claim, and the concrete thing etc. which illustrate the said term described in embodiment mentioned later.

  When an occupant carries a mobile phone and enters the vehicle, the mobile phone and a fixed installation device in the vehicle establish a wireless connection, and as a result, they can communicate with each other. However, in order for the mobile phone and the fixed installation device to establish a wireless connection, the fixed installation device needs to authenticate the mobile phone, and for this purpose, the mobile phone must authenticate the fixed installation device with a proper authentication code. Need to send.

  In this embodiment, the combination of a mobile phone and a fixed installation device that need to establish a wireless connection changes. In such a situation, the crew member for selecting a connection target mobile phone in the fixed installation device The work load and the work load of the crew for authentication can be eliminated.

  Hereinafter, a vehicle information communication system for realizing such an effect will be described. FIG. 2 schematically shows the configuration of the vehicle information communication system 10. The vehicle information communication system 10 includes an operation management center 1 installed at a business office of a vehicle operator, a mobile phone 2 that can communicate with the operation management center 1 via a wide area network 4, and a fixed installation device 3. . The vehicle information communication system 10 actually includes a plurality of mobile phones and fixed installation devices, but for simplicity, FIG. 2 representatively shows one mobile phone and one fixed installation device.

  The operation management center 1 is a device for transmitting data indicating the above arrangement schedule (hereinafter referred to as connection schedule data) to the mobile phone 2, and includes a network I / F 11 and a memory 12 for connecting to the wide area network 4. And CPU13. Further, the connection schedule data 12a is recorded in the memory 12. The CPU 13 acquires the connection schedule data 12a determined by the vehicle operator via a data input unit (not shown) (for example, a keyboard or a portable memory reader), and records the acquired connection schedule data 12a in the memory 12.

  FIG. 3 shows an example of connection schedule data in a table format. As shown in this figure, the connection schedule data consists of a plurality of records, and each record includes (1) a vehicle operation date, (2) an operation time zone, and (3) the time period (that is, the operation date and time zone). (4) A mobile phone that the crew should have at that time, (5) Identification information of the vehicle that the crew should board during that time, (6) Installed in the vehicle And (7) an authentication code dedicated to the fixed installation device necessary for wireless connection with the fixed installation device (that is, a proper authentication code unique to the fixed installation device) , Has a set of. The regular authentication code is different for each fixed installation device.

  The cellular phone 2 includes a wide area wireless communication I / F 21 for wireless connection to the wide area network 4, a Bluetooth I / F 22 for performing communication with the fixed installation device 3 via Bluetooth, a memory 23, and a CPU 24. The fixed installation device 3 includes a Bluetooth I / F 31 for communicating with the mobile phone 2 via Bluetooth, an in-vehicle LAN I / F 32 for communicating with various devices (such as a microphone and a speaker) in the vehicle via the in-vehicle LAN 5, and a memory 33. And a CPU 34.

  The function realized by the fixed installation device 3 communicating with the mobile phone 2 may be any type, for example, a well-known hands-free function may be realized. In that case, the CPU 34 acquires a voice signal from the other party using Bluetooth I / F 31 during a call on the mobile phone 2, and outputs the acquired voice signal to a speaker in the vehicle using the in-vehicle LAN I / F 32. Even if the voice uttered by the occupant is acquired via the microphone, the in-vehicle LAN 5, and the in-vehicle LAN I / F 32, it is transmitted to the cellular phone 2 using the Bluetooth I / F 31 as an audio signal addressed to the other party. Good.

  In addition, the fixed installation device 3 detects various vehicle running conditions via various in-vehicle LANs 5 from various sensors / actuators (for example, a camera outside the vehicle, a vehicle speed sensor, a GPS receiver, a fuel injection device, and an air bag actuator) mounted on the vehicle. A drive recorder that acquires information (for example, scenery outside the vehicle, traffic volume outside the vehicle, vehicle speed of the vehicle, position of the vehicle, fuel consumption rate, air bag activation / deactivation), and records the acquired information in a storage medium It may be. In that case, the function realized by the fixed installation device 3 communicating with the mobile phone 2 is, for example, the fixed installation device 3 determines the content of the driving operation advice for the crew based on the acquired information, and the determined content May be transmitted to the mobile phone 2, and the mobile phone 2 may display the contents. In addition, for example, the fixed installation device 3 detects an emergency situation (for example, the operation of an airbag) based on the acquired information, and transmits that fact to the mobile phone 2, and the mobile phone 2 uses the wide area wireless communication I / F 21. The occurrence of an emergency may be used to notify other out-of-vehicle communication devices such as an emergency management center.

  In FIG. 2, among the plurality of mobile phones and the plurality of fixed installation devices, the mobile phone 2 (corresponding to one example of the mobile phones X and P) and the fixed installation device 3 (corresponding to one example of the fixed installation device Y). ) Are representatively shown one by one, but other mobile phones and fixed installation devices also acquire and store connection schedule data distributed from the operation management center 1 in the same manner. The same operation as that of the cellular phone 2 and the fixed installation device 3 described below is realized.

  Hereinafter, operations of the operation management center 1, the mobile phone 2, and the fixed installation device 3 will be described in detail. First, the operation management center 1 transmits the connection schedule data 12 a to the mobile phone 2, and the mobile phone 2 transmits the connection schedule data 12 a to the fixed installation device 3. A sequence of the operation management center 1, the mobile phone 2, and the fixed installation device 3 in this operation is shown in FIG. In this operation, first, the CPU 13 of the operation management center 1 every time the connection schedule data 12a in the memory 12 is changed by the operator's operation (step 102), a new version number ( That is, a version number) is assigned, and the changed connection schedule data and information on the version number are transmitted to the mobile phone 2 (and other mobile phone) via the network I / F 11 (step 104).

  The CPU 24 of the cellular phone 2 receives the transmitted information via the wide area wireless communication I / F 21 (step 202), and records the received connection schedule data and the corresponding version number in the memory 23 (step 204). . Further, when the mobile phone 2 is in the vicinity of or in the vehicle on which the fixed installation device 3 is mounted, the CPU 24 corresponds to the latest (that is, the latest version number) connection schedule data in the memory 23 and the corresponding connection schedule data. Information on the version number is transmitted to the fixed installation device 3 via the Bluetooth I / F 22 (step 206).

  Then, the CPU 34 of the fixed installation device 3 receives the connection schedule data and the corresponding version number information via the Bluetooth I / F 31 (step 302), and records the received data in the memory 33 (step 304). Further, the CPU 34 transmits a notification that the connection schedule data has been received to the mobile phone 2 (step 306), the CPU 24 of the mobile phone 2 transfers the notification to the operation management center 1, and the CPU 13 of the operation management center 1 transfers the notification. The received notification is received and recorded in the memory 12 (step 106).

  In this way, the connection schedule data 12a in the operation management center 1 can be held in the mobile phone 2 and the fixed installation device 3 as well. In addition, in order to realize the connection schedule data between the mobile phone 2 and the fixed installation device 3 and the transfer by wireless communication of the corresponding version number, the wireless connection must be established between the mobile phone 2 and the fixed installation device 3. is required. A method for establishing the wireless connection at this time will be described later.

  Next, an operation procedure for wirelessly connecting the mobile phone and the fixed installation device in accordance with the schedule of the connection schedule data will be described. In FIG. 5, a mobile phone B as an example of the mobile phone 2 (corresponding to an example of the mobile phone X) and other mobile phones A and C are placed in or near the vehicle on which the fixed installation device 3 is mounted. The situation is illustrated. Then, according to the latest connection schedule data, the mobile phone B is arranged to be connected to the fixed installation device 3 at the current date and time. Each of the mobile phones A and C can realize the same configuration and operation as the mobile phone 2, that is, a mobile phone possessed by the vehicle operator, or a mobile phone having another Bluetooth communication function. In the following description, it is assumed that the mobile operator has a mobile phone.

  First, a crew member who possesses each of the mobile phones A to C inputs his / her crew identification information (for example, by operating an operation button). Then, each CPU 24 of the mobile phones A to C records the inputted crew member identification information in the memory 23 (steps 211, 212, and 213).

  Subsequently, the mobile phones A to C transmit a connection request and a Bluetooth physical address unique to the mobile phone A to C as a normal function of Bluetooth to the nearby fixed installation device 3. Further, the CPU 34 of the fixed installation device 3 always detects whether or not there is a connection request by using the Bluetooth I / F 31 as a normal function of Bluetooth.

  Then, the CPU 34 of the fixed installation device 3 periodically executes a connection schedule search process (step 312). In the connection schedule data search process at a certain time, it is determined whether or not a connection request has been received after the previous connection schedule data search process. If so, the current date and time of the fixed installation device 3's own identification information The set (or the set of the current date and time and the identification information of the vehicle on which the fixed installation device 3 is mounted) is applied to the latest connection schedule data in the memory 33. Specifically, the record having the set is searched from the connection schedule data. Then, the identification information of the mobile phone in the record found as a result (specifically, the Bluetooth physical address of the mobile phone) is determined as the mobile phone to be connected to the current device. In the example of FIG. 5, the mobile phone of the connection partner is a mobile phone B.

  Further, the CPU 34 transmits a signal requesting an authentication code to the determined mobile phone B of the connection partner using the Bluetooth I / F 31 (step 316). Since the signal for requesting the authentication code transmitted in this way is the Bluetooth physical address of the cellular phone B, the cellular phones A and C do not receive it. Accordingly, as a result, the fixed installation device 3 requests an authentication code from a mobile phone to be connected at the current date and time, and does not request an authentication code from other mobile phones.

  Then, the CPU 24 of the cellular phone B receives the request for the authentication code via the Bluetooth I / F 22 (step 216), and executes connection schedule data search processing based on the reception of the request (step 218). . In this connection schedule data search process, the set of the current date and time and the crew identification information recorded in step 212 is applied to the latest connection schedule data in the memory 23. Specifically, the record having the set is searched from the connection schedule data. Then, the authentication code in the record found as a result is determined as a proper authentication code inherently to the fixed installation device to be connected to the current device.

  Then, the CPU 24 transmits the determined authentication code to the fixed installation device 3, and the CPU 34 of the fixed installation device 3 receives the authentication code to permit establishment of wireless connection with the mobile phone B by Bluetooth, and thereafter The Bluetooth connection between the fixed installation device 3 and the mobile phone B (that is, wireless connection by Bluetooth) is realized by a normal Bluetooth wireless connection procedure. Thereafter, various data for the application as described above is exchanged between the mobile phone 2 and the fixed installation device 3.

  As described above, each of the plurality of mobile phones owned by the operator records the identification information of the crew member input by the crew member carrying the mobile phone among the plurality of crew members (see steps 211 to 213). ). As a result, information on which passenger currently owns the mobile phone is recorded in each of the mobile phones.

  When a connection request is transmitted from the mobile phone B (and mobile phones A and C in some cases) belonging to the plurality of mobile phones to the fixed installation device 3 which is one of the fixed installation devices, the fixed installation device 3 determines the mobile phone to be currently connected to itself by applying the current date and time and the identification information of the fixed installation device 3 to the connection schedule data recorded by itself (see step 312). When each of the mobile phones A, B, and C is a mobile phone to be connected, an authentication code is requested from the mobile phone (in the example of FIG. 5, the mobile phone B corresponds to this case). In addition, when the mobile phone is not the mobile phone to be connected, the mobile phone does not request an authentication code (in the example of FIG. It corresponds to).

  In this way, when there is a connection request, the fixed installation device 3 refers to the connection schedule data, and if the connection request source is a mobile phone to be connected to itself, an authentication code is provided. Request, otherwise do not request an authentication code. By such an operation of the fixed installation device 3, a wireless connection partner of the fixed installation device 3 is automatically selected. Therefore, it is not necessary for the crew to operate the fixed installation device 3 to select the mobile phone of the wireless connection partner, and as a result, the work load on the crew is reduced.

  In addition, the mobile phone B receives the request for the authentication code from the fixed installation device 3, and the current date and the identification information of the crew recorded by itself are stored in the connection schedule data recorded by itself. By applying, the authentication code that is legitimate for the fixed installation device 3 to be connected by itself at the current date and time is determined (step 218), and the determined authentication code is transmitted to the fixed installation device 3.

  Then, the fixed installation device 3 permits the mobile phone B to establish a wireless connection with itself based on the reception of the authentication code transmitted from the mobile phone B.

  As described above, when the mobile phone B receives the request for the authentication code, the mobile phone B determines the authentication code that is legitimate for the fixed installation device 3 to which the mobile phone B should connect. Therefore, the authentication code is automatically input to the fixed installation device 3, and the crew does not need to manually input the authentication code. As a result, the work load on the crew is reduced.

  As described above, in order to realize the transfer of connection schedule data from the mobile phone 2 to the fixed installation device 3, it is necessary to establish a wireless connection between the mobile phone 2 and the fixed installation device 3. However, on the other hand, in order to establish a wireless connection by the procedure as shown in FIG. 5, there arises a contradiction that the fixed installation device 3 must have connection schedule data.

  As a mechanism for resolving this contradiction, the mobile phone 2 transmits the received connection schedule data to the fixed installation device 3 without transmitting a normal authentication code for the fixed installation device 3. Also good. And in the connection schedule data search process shown by step 312 of FIG. 5, the fixed installation apparatus 3 is based on not having recorded the connection schedule data, when its memory 33 has not recorded the connection schedule data. By canceling the prohibition of wireless connection with the mobile phone 2 that has not transmitted a normal authentication code, the wireless connection with the mobile phone 2 is established, and then the schedule data transmitted from the mobile phone 2 is It may be received and recorded.

  As described above, when the fixed installation device 3 does not have the connection schedule data, the wireless connection is exceptionally permitted without receiving the normal authentication code, so that the mobile phone 2 can move to the fixed installation device 3. Exchange of connection schedule data is realized. Note that the mobile phone that transmits the connection schedule data to the fixed installation device 3 and the mobile phone that is wirelessly connected to the fixed installation device 3 in the procedure described in FIG. 5 may be the same mobile phone or different mobile phones. It may be.

  In addition, after the wireless connection by Bluetooth between the fixed installation device 3 and the mobile phone 2 is established, the mobile phone 2 and the fixed installation device 3 execute an operation for matching the versions of the connection schedule data. FIG. 6 shows an operation procedure performed by the mobile phone 2 and the fixed installation device 3 for this operation.

  In this operation, first, the CPU 24 of the mobile phone 2 transmits information on the version number corresponding to the latest connection schedule data recorded in the memory 23 of its own device to the fixed installation device 3 (step 221). The CPU 34 of No. 3 receives the version number information (step 321).

  Subsequently, the CPU 34 compares the received version number with the version number corresponding to the latest connection schedule data recorded in the memory 33 (step 322). If the received version number is older, the latest connection schedule data in the memory 33 and the corresponding version number are transmitted to the mobile phone 2 (step 324). The CPU 24 (step 222) records the received connection schedule data and the corresponding version number in the memory 23 (step 224).

  If the received version number is newer as a result of the comparison, the CPU 34 transmits a signal requesting connection schedule data to the mobile phone 2 (step 327), and the CPU 24 of the mobile phone 2 receives the signal (step 327). In step 225), the latest connection schedule data in the memory 23 and the corresponding version number are transmitted to the fixed installation device 3 (step 226), and the CPU 34 of the fixed installation device 3 that has received the connection schedule data (step 327) The schedule data and the corresponding version number are recorded in the memory 33 (step 329).

  By such an operation, both the mobile phone 2 and the fixed installation device 3 have the latest connection schedule data among the connection schedule data of either the mobile phone 2 or the fixed installation device 3.

(Second Embodiment)
Next, a second embodiment of the present invention will be described. This embodiment is different from the first embodiment in the detailed part of the mechanism for passing connection schedule data from the mobile phone 2 to the fixed installation device 3 in the stage before realizing the wireless connection as shown in FIG. .

  FIG. 7 shows a procedure of operations performed by the fixed installation device 3 and mobile phones A, B, and C (as an example of the mobile phone 2) for delivery of connection schedule data in the present embodiment.

  First, a crew member who possesses each of the mobile phones A to C inputs his / her crew identification information. Then, each CPU 24 of the mobile phones A to C records the input crew member identification information in the memory 23 (steps 231, 232, and 233).

  Subsequently, the mobile phones A to C transmit a connection request and a Bluetooth physical address unique to the mobile phone A to C as a normal function of Bluetooth to the nearby fixed installation device 3.

  Then, the CPU 34 of the fixed installation device 3 periodically executes a connection schedule search process similar to step 312 of FIG. 5 in the first embodiment (step 332). In the connection schedule data search process at a certain time, it is determined whether or not a connection request has been received after the previous connection schedule data search process. If so, the current date and time of the fixed installation device 3's own identification information The set (or the set of the current date and time and the identification information of the vehicle on which the fixed installation device 3 is mounted) is applied to the latest connection schedule data in the memory 33. Specifically, an attempt is made to find a record having the set from the connection schedule data. However, in this case, connection schedule data is not recorded in the memory 33. In such a case, the CPU 34 selects one of the mobile phones A, B, and C as the transmission source of the received connection request (step 334), and the selected mobile phone (mobile phone B in FIG. 7). A signal requesting an authentication code is transmitted (step 335). Here, the cellular phone to be selected may be any of cellular phones A, B, and C. For example, the mobile phone A, B, or C that has transmitted the connection request first may be selected.

  When receiving the authentication code request (step 234), the CPU 24 of the mobile phone B executes a connection schedule data search process similar to step 218 of FIG. 5 in the first embodiment (step 235). In this connection schedule data search process, it is determined whether or not the received authentication code request is out of the schedule in light of the connection schedule data in the memory 23. The code is transmitted to the fixed installation device 3.

  Here, whether or not the authentication code request is out of schedule is determined based on the current date and time, the crew identification information recorded in step 232, and the identification information of the own aircraft, by the latest connection schedule data in the memory 23. If the corresponding record is found, it is determined that the authentication code request is not out of schedule. If not found, the authentication code request is determined to be out of schedule. If it is determined that the schedule is not out of schedule, the process of step 218 in FIG. 5 is executed.

  The temporary authentication code transmitted here is a regular common authentication code for all of the plurality of fixed installation devices owned by the operator. Such an authentication code is determined in advance at the time of construction of the vehicle information communication system, and is recorded in all the memories 23 of the plurality of mobile phones possessed by the operator. Further, when each of the plurality of fixed installation devices possessed by the operator receives this common authentication code, the wireless connection with the mobile phone that is the transmission source of the code is permitted.

  When receiving the temporary authentication code (step 336), the CPU 34 of the fixed installation device 3 establishes a wireless connection with the transmission source mobile phone B as described above. Thereafter, the CPU 34 transmits a signal requesting connection schedule data to the mobile phone B (step 338). When the CPU 24 of the mobile phone B receives the request (step 238), the latest information is received in response to the request. The connection schedule data and the corresponding version number are transmitted (step 239). Then, the CPU 34 of the fixed installation device 3 receives the latest connection schedule data and version number transmitted and records them in the memory 33 (step 340), and then disconnects the wireless connection with the mobile phone B (step 342). ).

  Thus, the mobile phone B (corresponding to an example of the mobile phone P) transmits the received connection schedule data and a common authentication code that is legitimate for all the fixed installation devices to the fixed installation device 3, Based on the reception of the common authentication code, the fixed installation device 3 cancels the prohibition of wireless connection with the mobile phone B, and receives and records the schedule data transmitted from the mobile phone B. In this way, by using the common authentication code that is legitimate for any of the plurality of fixed installation devices as an exception for the delivery of connection schedule data, the connection schedule data from the mobile phone to the fixed installation devices Delivery is realized.

(Other embodiments)
As mentioned above, although embodiment of this invention was described, the scope of the present invention is not limited only to the said embodiment, The various form which can implement | achieve the function of each invention specific matter of this invention is included. It is.

  For example, in the above embodiment, the mobile phone B applies the crew identification information recorded by itself to the connection schedule data in order to determine a proper authentication code for the fixed installation device 3 to be connected. However, the identification information of the mobile phone B may be applied in place of the crew member identification information.

  There is also an implementation form of the present invention in which the fixed installation device 3 does not have to receive the connection schedule data from the mobile phone 2. For example, the fixed installation device 3 has an interface for reading a portable storage medium. An operator inserts a storage medium for storing connection schedule data into the interface, and the fixed installation device 3 receives the connection schedule data. You may read and memorize | store.

  Similarly, the mobile phone 2 may not have to receive connection schedule data from the operation management center 1 in some cases. For example, the mobile phone 2 has an interface for reading a portable storage medium. An operator inserts a storage medium for storing connection schedule data into the interface, and the mobile phone 2 reads the connection schedule data. You may come to memorize. In such a case, the operation management center 1 is not essential for the vehicle information communication system.

  The communication method between the mobile phone 2 and the fixed installation device 3 is not limited to Bluetooth, but any wireless communication that requires selection of a connection partner and exchange of an authentication code for wireless connection is possible. It may be a method.

  In addition, the mobile wireless communication terminal to be wirelessly connected to the fixed installation device 3 is not limited to a mobile phone, and may be a PDA or a notebook personal computer.

  In the above embodiment, the CPU 13 of the operation management center 1, the CPU 24 of the mobile phone 2, and the CPU 34 of the fixed installation device 3 are general-purpose CPUs. However, instead of these CPUs, the operation management center 1, the mobile phone 2, and the fixed installation device 3 are devices (for example, FPGA) having a dedicated circuit configuration for realizing their functions. You may come to have.
