Namely, the navigation system that is originally one of unspecified number of terminal devices on a communication network is aggressively accessed and the service information is transmitted. Thus, services of necessary and sufficient contents can be provided at any appropriate time.

Description

The present invention provides, for example, an electronic device as a system constructed so that an electronic device mounted on a mobile object such as an automobile and a personal mobile terminal device such as a server and a mobile phone can communicate with each other via a communication network. The present invention relates to a terminal that can provide a service that can be enjoyed by an electronic device that has received transmitted data by performing some operation in accordance with the content of the received data for a user who has purchased and used the data. Is.

So-called car navigation devices are widely used. As its basic function, for example, a current position of a moving car or the like is measured, and the measured current position is displayed on a map to inform the user of the current position.
In recent years, a car navigation device having a function capable of connecting to the Internet by providing a mobile wireless terminal device has also become widespread. For example, by accessing a website on the Internet, for example, information on stores in a specific area, information on events, weather, and the like are displayed on the display part of the car navigation device. It is possible to obtain.

By the way, for a user who has purchased a product, for example, a so-called aftercare, after-sales service, etc., which is useful for the user who has purchased the product, is often provided from the manufacturer or store that manufactured and sold the product. Done.
The car navigation apparatus as described above is also originally a product, for example, purchased and acquired by the owner of the car on which it is mounted. Therefore, if a sales side such as a company or a store provides an after-sales service for such a car navigation device, it is possible to provide convenience to the user and increase the added value of the company's products.

However, the way of providing services from the company side is limited to, for example, notification by mail or electronic mail at present, and there is a limit when seeking higher convenience.
Therefore, for example, by providing a service server on the Internet and transmitting data related to the service directly to a car navigation device having an Internet connection function, the user can be more directly connected to the user. It is possible to provide a service for this.
However, in the present situation, the car navigation device has only a function of connecting to the Internet, and for example, the car navigation device cannot be accessed from the server side as described above. That is, at the present stage, even if the service is provided using the Internet communication function, the user grasps the address (URL) of the service server and then operates the car navigation device to It is necessary to access the service server from the device side. This means that at the time when the service is required on the part of the company, the car navigation device cannot be immediately accessed to provide the service. Cannot be provided.

Therefore, the present invention is configured as follows in consideration of the above-described problems .
A terminal including a navigation function having a unique ID, comprising a wireless communication unit for transmitting and receiving information over a communication network, and a control unit having a processor,
The processor can process a predetermined service provided by a service providing system received by the wireless communication unit, and the service providing system stores a unique ID of the navigation terminal, and the navigation terminal is authenticated. Only when the navigation terminal is accessed and the predetermined service is provided, the predetermined service being an update of map information available on the navigation terminal, and an updated map with the previous version of the map information Data of only the difference between information is received by the wireless communication unit.

As described above, the present invention is unique to each car navigation system on the server side in providing a service to a car navigation system (electronic device) having a function of connecting to a communication network such as the Internet by wireless communication. A car navigation system that is intended to provide a service among car navigation systems that are originally an unspecified number of terminals on the Internet by having and managing the navigation ID (device ID) assigned to It is possible to access data and perform data communication necessary for service provision.
For example, conventionally, access must first be made from the car navigation system side. For example, the server side can only provide service information after waiting for this access. On the other hand, in the present invention, since it becomes possible to access a specific car navigation system from the server or the mobile phone (mobile radio terminal device) side, it is necessary at any appropriate occasion. It is possible to provide a service with sufficient contents. This also makes it possible to easily increase the types of services that can be provided. Therefore, for example, users who have purchased a car navigation system can enjoy service provision in a simpler and more effective manner than before, and the added value of the product will increase for both the sales side. The effect can also be expected.

Further, when communication is performed from a communication terminal device (personal computer) fixedly installed indoors to an electronic device (for example, a navigation system), an authentication server is interposed. Also, when the communication terminal device accesses the authentication server to communicate with the electronic device, a terminal ID (PC-ID) is generated using information (phone number, port number, router address, etc.) specifying the access route. Like to do. The authentication server performs authentication processing using the terminal ID.
The information that identifies the access path is usually information that cannot be tampered with on the communication terminal device side because the side that operates the communication network to which the communication terminal device is connected first manages and holds the information. Therefore, it can be said that the terminal ID is information that cannot be falsified. That is, according to the present invention, unauthorized use of services by so-called impersonation can be reliably prevented with a simple configuration.

Stored as evidence information.

1-3. Internal Configuration of Navigation Main Body FIG. 3 is a block diagram showing the internal configuration of the navigation main body 2.
In FIG. 4, the positioning unit 4 is a part that measures the current position of the host vehicle, and executes, for example, predetermined calculation processing based on GPS reception data transferred from the interface 14 and traveling information of the host vehicle. Thus, latitude / longitude information is obtained as position information indicating the current position of the host vehicle.

A ROM (Read Only Memory) 11 stores various programs for the navigation system 1 according to the present embodiment to execute a required process, and various factory preset data that cannot be rewritten in principle.
The memory 12 is an EEPROM (Electrically Erasable Read Only Memory) that can hold stored contents even when no power is supplied, such as a flash memory, and stores so-called backup data. There are various types of backup data here. For example, various types of information including a destination set by the user and a route corresponding to the destination are stored.
However, the ROM 11 can be rewritten (for example, so-called update) as necessary by adopting a rewritable memory element such as a nonvolatile memory or a flash memory. It becomes. In the present embodiment, it is assumed that the ROM 11 is also rewritable.

  In the present embodiment, the memory 12 stores a navigation ID uniquely given to the navigation system 1. This navigation ID is assigned at the time of user registration at the time of purchase decision, for example, and written at the stage until it reaches the user's hand. Further, after the purchase, when the navigation system 1 is connected to the Internet and user registration is performed online, the navigation ID assigned and transmitted from the service server 500 is written in the memory 12. Good.

  A DRAM (Dynamic Random Access Memory) 13 is used as a work area when the control unit 19 executes various processes, and generates navigation image information based on map information reproduced from the recording medium 9 by the disk driver 18. The processing for this is also executed using this DRAM 13.

The interface (I / F) 14 is provided to connect the external device and the navigation main body 2.
In this case, the reception data from the GPS antenna 5 is input to the interface 14. Further, data of road traffic information received by the traffic information antenna 7 is input. A vehicle speed pulse detected by the vehicle speed sensor of the autonomous navigation unit 6 is input. Further, the traveling direction information of the host vehicle detected by the gyro 6b is input via the terminal 32.
Data received from the GPS antenna 5 and travel information (vehicle speed pulse and travel direction information) from the autonomous navigation unit 6 are transferred to the positioning unit 4 via the bus 20. The positioning unit 4 inputs these transferred information as parameters and measures the current position of the vehicle.
Further, road traffic information data from the traffic information antenna 7 is written and held in the DRAM 13 under the control of the control unit 19, for example, and by referring to the road traffic information written in the DRAM 13 by the control unit 19, For example, image processing control or the like is executed so that road information such as traffic congestion is reflected in the map information image data to be displayed and output to the display monitor unit 3.

  The clock unit 15 measures the current date and time, and the time information is used for time management required in the navigation system 1.

  The input unit 16 is connected to the receiving unit 3b of the display monitor unit 3, and receives a command signal from the remote controller 8 received by the receiving unit 3b. The input command signal is converted into a format that can be transmitted by the internal bus 20, and then transferred to the control unit 19 via the bus 20. The control unit 19 appropriately executes necessary control processing based on the input command signal.

The display driver 17 generates image information for display under the control of the control unit 19 and outputs the image information to the display screen unit 3 a of the display monitor unit 3 via the terminal 34.
For example, based on the map information read from the recording medium 9 and the current position information of the own vehicle calculated by the positioning unit 4, an image signal indicating the current position of the own vehicle is generated and output to the display monitor unit 3.

  The disk driver 18 is a part for reproducing the recording medium 9 and is configured to be provided with a reproducing function corresponding to a media format actually employed as the recording medium 9. For example, map information or the like reproduced from the recording medium 9 is transferred to the DRAM 13 via the bus 20 and held therein, and is referred to by the control unit 19 and used as display data at a required timing.

The image sound processing unit 46 performs necessary digital signal processing on the input captured image signal and sound signal, and finally converts them into record data in a format that can be recorded in the storage unit 45. Here, the captured image signal input to the image / sound processor 46 is a plurality of signals from the in-vehicle camera 3c, the front camera 3d, and the external camera 42. The signals input at the same time are first converted into digital data, and then each image signal data is converted into compressed moving image data of a predetermined format by time division processing.
The audio signal input to the image / audio processing unit 46 is a signal from the microphone 43. This audio signal is also converted into digital data and then converted into compressed audio signal data of a predetermined format, for example.
The compressed moving image data and compressed audio signal data obtained in this way are transferred to the storage unit 45 via the internal data bus 20 and written by the control of the control unit 19.

  When recording moving image data and audio data to the storage unit 45, for example, when the recordable capacity becomes full during the recording process, the most recently recorded moving image data and audio data are recorded. The latest captured image data and audio data are recorded by overwriting and erasing the data. In this way, the storage capacity of the storage unit 45 may be relatively small. If this recordable capacity is, for example, about several tens of minutes in terms of time, it is sufficiently suitable for the purpose of leaving evidence.

  Note that the image / audio processing unit 46 may have a decoding function for reproducing and outputting the image / audio data recorded in the storage unit 45, for example. If such a decoding function is provided, for example, the image / sound data recorded in the storage unit 45 can be reproduced and output on the display unit 3.

The communication interface 47 controls data transmission / reception between the communication terminal device 50 and the navigation main body 2. For example, when data is output from the communication terminal device 50 to the navigation main body 2, the communication interface 47 converts the data input from the communication terminal device 50 into a format that can be processed in the navigation main body 2. Then, the data is output to a required functional circuit unit via the data bus 20.
Conversely, when data is transferred from the navigation main body 2 to the communication terminal device 50, it is converted into data in a format that can be processed by the communication terminal device 50 and output to the communication terminal device 50. Is done.

  In addition, here, the operation control for the communication terminal device 50 is executed by the control unit 19 of the navigation main body 2. That is, the communication terminal device 50 and the navigation main body 2 perform wireless communication in cooperation with each other, so that the navigation system 1 according to the present embodiment is provided with a communication function with the Internet, for example.

  The control unit 19 is configured to include, for example, a CPU (Central Processing Unit), and performs necessary control on each circuit unit. Thereby, various operations in the navigation system as described above are realized.

1-4. Internal Configuration of Mobile Phone The block diagram of FIG. 2 simply shows the internal configuration of the mobile phone according to the present embodiment.
The radio wave received by the antenna 201 is received and demodulated by the receiving circuit 202 and output to the signal processing circuit 204. If this received wave is, for example, voice data of the other party in a call, the signal processing circuit 204 demodulates the voice signal and outputs it to the speaker 206, for example. For example, if the received wave is information of so-called data communication such as mail or the Internet, such communication data is demodulated. The demodulated communication data can be displayed on the LCD display unit 209 under the control of the system controller 208.
For example, when it is necessary to output an electronic sound at the time of operation or a ringing sound at the time of an incoming call, for example, the system controller 208 controls the ringer 205 to generate a required ringer sound, and the audio signal Is output to the speaker 206.

  For example, the user's voice collected by the microphone 207 during a call is input to the signal processing circuit 204 as a voice signal. In the signal processing circuit 204, the audio signal is subjected to a predetermined encoding process and output to the transmission circuit 203. The transmission circuit 203 transmits and outputs the signal input from the signal processing circuit 204 via the antenna 1.

The system controller 208 executes various control processes so that various operations by the mobile phone are performed.
The system controller 208 includes a ROM 217 and a RAM 218. The ROM 217 is a rewritable memory configured by, for example, a flash memory or an EEPROM, and stores a program and display data to be executed by the system controller 208. Further, various data set and registered by the user, such as phone book data and sent / received mail data, are also stored and held.
Further, in the present embodiment, the portable telephone ID uniquely given to the portable telephone 200 is attached to the ROM 217. In the case of a mobile phone, this may be information on the assigned telephone number.

  The key operation unit 210 includes a plurality of predetermined button keys, and outputs an operation information signal corresponding to an operation on these button keys to the system controller 208. Based on the operation information signal, the system controller 208 executes control processing so that a required operation is obtained.

  Further, as shown in the figure, the LCD display unit 209 is driven so as to display the contents according to the operation status under the control of the system controller 208.

  Note that the internal configuration of the communication terminal device 50 provided in the navigation system 1 also conforms to the configuration shown in FIG. However, in the case of the communication terminal device 50, it is not necessary for the user to carry it and use it for a call or the like, so from the circuit shown in FIG. 4, for example, the ringer 205, the speaker 206, the microphone 207, and the LCD display Functional circuit units such as the unit 209 and the key operation unit 210 can be omitted. It is only necessary to provide an interface function capable of exchanging data with the communication interface 47 in the navigation main body 2.

1-5. Internal Configuration of Application Server FIG. 5 simply shows an internal configuration example of the application server 303 that is assumed to be provided in the wireless telephone communication network 300.
The application server 303 includes, for example, a storage unit 401, interfaces 402 and 403, and a control unit 404 as illustrated.
The storage unit 401 stores various types of information necessary for realizing the function as an application server. Here, a user database 410 and an execution application 411 are shown as representative data stored in the storage unit 401.

For example, as shown in the lower part of the figure, the user database 410 stores user information, a mobile ID, a navigation ID, and a password associated with the user of the navigation system 1 and the mobile phone 200 in association with each other.
As the user information, for example, information related to various types of individual users required for services such as the user's name and address and the date of birth is stored.
The mobile ID stores the same data as the mobile ID written in the mobile phone owned by this user. Similarly, the navigation ID stores the same navigation ID data assigned to the navigation system 1 owned by the user. The navigation ID may be a telephone number assigned to the wireless terminal device 50, for example. If the navigation ID is a telephone number, the navigation system can be accessed from the application server 303 or the service server 500, for example. It is possible to easily access one wireless terminal device.
For example, when the navigation system 1 is accessed from the mobile phone 200 via the wireless telephone communication network 300, the mobile phone 200 that has requested access is authenticated in order to obtain authentication. The user performs a password input operation on the telephone 200, and this value is stored as the password in the user database 410.

By the way, as the contents of the user database 410 shown in FIG. 5, information for each individual user can be created by acquiring necessary information at the following occasions, for example.
For example, the navigation system 1 can be purchased by so-called Internet shopping using the Internet. When performing a purchase procedure by such Internet shopping, for example, the user inputs required personal information on an input form displayed on the browser screen. Further, in the case of the navigation system 1 having the wireless terminal device 50 as in the present embodiment, a contract with a communication company for making the wireless terminal device 50 available is made when purchasing the navigation system 1. To be. In this embodiment, the application server 303 (or the service server 500) receives these pieces of information by communicating with a sales company server for Internet shopping, and creates and registers it as a database. Is. That is, if the user has purchased the navigation system 1 by Internet shopping, the registration work required to create the user database 410 later is not necessary.
Moreover, the navigation system 1 of this Embodiment can also be purchased in combination with, for example, car insurance that is an intangible product as a purchase form in Internet shopping. In this case, for example, the price of the car insurance and the navigation system 1 is discounted, and in the case of a split payment contract, a service is provided in which the split fee is free or discounted. When the navigation system 1 is purchased in combination with the car insurance in this way, the user information as the user database 410 is obtained at the stage of input to the input form for purchasing the car insurance. You can also.
As for the mobile ID and the password, for example, when a security service contract is made by operating the mobile phone 200, the data input and transmitted by the user may be received, acquired, and stored. Of course, in the above-mentioned purchase procedure of the navigation system 1 by Internet shopping, a mobile phone that can use the security service can be registered, and at this time, the mobile ID and password may be notified. is there.

  The execution application 411 includes various application programs corresponding to various operations to be executed by the application server 303. For example, an application program that controls the function of sending and receiving mail via the Internet, a connection process with the Internet in response to an access request to a Web page from the mobile phone 200 or the navigation system 1, and a search for the user database 410 Application programs.

The interface 402 is provided for information transmission / reception with the relay station 302 side, and the interface 403 is provided for information transmission / reception with the gateway 304 (Internet) side.
The control unit 404 executes various control processes according to the program contents as the execution application 411.

1-6. Internal Configuration of Service Server FIG. 6 schematically shows an exemplary internal configuration of the service server 500.
The service server 500 shown in this figure includes a storage unit 501, a network interface 502, and a control unit 503.
Also in this case, the storage unit 501 stores various types of information necessary for realizing a function as a server that provides various services. Here, as representative data stored in the storage unit 501, a user database 510, an execution application 511, and service data 512 are shown.

The user database 510 may have the same contents as the user database 410 described above with reference to FIG. 5, for example, and the user database 510 always has the same contents by communicating with the application server 303, for example. . In other words, when the contents of the user database are updated in either one of the application server 303 or the service server 500 due to a new user contract or the like, the other server is notified that the user database has been updated. Thus, rewriting is executed so that the contents of the user databases are not inconsistent.
In this case, the execution application 511 includes various application programs corresponding to various operations to be executed by the service server 500. Further, the service data 512 is various service data to be transmitted to the communication terminal device such as the navigation system 1 or a mobile phone when providing the service.
The network interface 502 is provided as an interface unit for connecting to the Internet.
The control unit 503 executes various control processes according to the program contents as the execution application 411.

2. Example of Service Provision by System In the service provision system having the above configuration, communication is performed between the navigation system 1, the mobile phone 200, and the service server 500 through the radio telephone communication network 300 and the communication network of the Internet 400. It becomes possible. Then, using the communication function between the systems, for example, the following services can be provided to the user as this embodiment.

Here, for example, for a certain type of navigation system 1, it is assumed that the latest version of a medium on which map information shown as the recording medium 9 is recorded is newly created.
In such a case, for example, the service server 500 searches the user database 510 for a user who owns the navigation system 1 that can reproduce the latest version of the media. Then, content data for recommending the latest version of the media as service data 512 is transmitted to the application server 303 of the wireless telephone communication network 300 together with the navigation ID of the wireless terminal device 50 of the searched user navigation system 1. This content data can be displayed and output on the display screen 3a of the display unit 3, for example, such as "New map disc is out. Please purchase if you like. How to get ..." Data.
When the application server 303 receives the user ID and the content data, the application server 303 transmits the content data to all the navigation systems 1 of the received user ID.
The content data is received by the wireless terminal device 50 of the navigation system 1 and transferred to the navigation main body 2. Then, under the control of the control unit 19, the received content data is displayed and output on the display screen 3 a of the display unit 3. By looking at the content of the message displayed in this way, the user can know that a new map information disk is provided by the manufacturer.

  Note that when such content data is received, it is not always possible for the user to see the content data displayed on the display screen 3a while in a car. Therefore, for example, when the main power of the navigation system 1 is not turned on, for example, when driving is not performed, when the content data is received by the wireless terminal device 50, the main power is automatically turned on and received. Thus, the acquired content data is stored in the memory 12 or the storage unit 45. For example, when the user turns the ignition key of the automobile and the main power supply of the navigation system 1 is turned on, the content data may be displayed on the display screen 3a.

Alternatively, in a state where the navigation system 1 is operating, information indicating that it is currently operating is transmitted from the navigation system 1 to the service server 500 side together with the navigation ID every predetermined time. Also good. In response to the transmission of this information, the service server 500 transmits the content data to the navigation system 1 with the received navigation ID. In this way, content data can be efficiently transmitted only when the navigation system 1 is operating.
Further, as this development, for example, the current position measured by the positioning unit 4 is transmitted from the navigation system 1 to the service server 500 side every predetermined time. Then, when the service server 500 determines that the transmitted current position is a road that is newly supported by the latest media, for example, it is a suitable opportunity to recommend the latest version, It is conceivable to transmit data. In this way, the service becomes more fulfilling.

In addition, for a certain type of navigation system 1, a service in which an updater obtained by upgrading a program as a system on the manufacturer side is also conceivable.
In brief, in the service server 500, the updater is prepared as one of the service data 512. Then, the updater is transmitted to one or more specific navigation systems 1 at a necessary appropriate opportunity.
In the navigation system 1, for example, a program or preset data stored in the ROM 11 is rewritten using the received update data. In this way, for example, even if the user does not bother to obtain the upgrade media, the upgrade of the navigation system 1 is performed by online data communication. In addition, in this case, the version upgrade is automatically performed, which is a very useful service for the user.

In addition, it is possible to perform control related to the security of the automobile from a remote place by operating the mobile phone 200 by the user. This operation will also be briefly described.
For example, the user operates the mobile phone 200 to access the application server 303 of the wireless telephone communication network 300. The server accessed here is assumed to be a server for security control of the automobile (it is assumed that the application server 303 exists). Further, the user makes an inquiry as to whether or not the car key is locked by performing a predetermined operation. In response to this request, the security server in the application server 303 searches for the navigation ID of the navigation system 1 owned by the same user as the mobile phone that has accessed, and for the navigation system 1 of the searched navigation ID. , Send a key lock inquiry command.

  In the navigation system 1 that has received this command, based on the information from the lock control unit 44 of the security system unit 41, key lock information as to whether or not the key is currently locked is transmitted to the application server 303. The application server 303 transmits the key lock information so as to be transferred to the mobile phone 200. In the mobile phone 200, for example, based on the key lock information, information indicating whether or not the user's car is locked is indicated by a display or the like.

For example, if the key is not locked, the user operates the mobile phone 200 to transmit instruction information for instructing key lock. The application server 303 that has received this instruction information transfers this instruction information to the navigation system 1. In the navigation ID navigation system 1 that has received the instruction information, the key lock control unit 44 operates to lock the car.
That is, by using the mobile phone 200, for example, it is possible to check whether or not a car is locked, and if it is not locked, it can be controlled to lock it. .

  On the other hand, when the key is opened due to, for example, aiming on the vehicle, the mobile phone 200 notifies the mobile phone 200 that the key has been opened by communication with the communication terminal 50 from the navigation system 1 side. It is also possible to calibrate to report.

  Further, as similar to the provision of update data, update data of map information used in the navigation system 1 is provided (transmitted), and the navigation system 1 always uses the update data to display the latest map information. A service to do is also conceivable.

As described above, in the navigation system 1, the map information recorded on the recording medium 9 is used to display the current position on the map, but the navigation system 1 is manufactured. It is assumed that the manufacturer that sells the map information is sequentially updated.
Then, the service server 500 holds the updated map information as one of the service data 512.

  In this case, the content and format of the update data are not particularly limited, but here, for example, it is assumed that only the difference data from the map information before the update is included. That is, for example, if updating is performed by adding a new road on the map, difference data for displaying the new road at an appropriate position is used as update data. In this way, if the update data is in the form of difference data, for example, the service server 500 does not need to store all map information including update contents as update data to be stored in the service data 512. The storage capacity of the storage unit 801 can be saved.

  In this case, notification to the user that the map information has been updated may be performed in the same manner as the transmission of the content data that recommends the purchase of the latest version of the medium on which the previous map information is recorded. Then, by displaying the transmitted content data on the navigation system 1, for example, the user can know that the map information has been updated and that the updated data can be downloaded and acquired. .

  And when a user wants to acquire the update data of map information, predetermined operation for instruct | indicating the download of map information is performed with respect to the navigation system 1, for example. This operation is configured such that, for example, an application for download using XML or HTML included as the content data described above is displayed as a GUI on the display screen 3a, and a predetermined operation can be performed on this GUI. Can be considered.

If the operation is performed as described above, the navigation system 1 transmits a request for update data together with its own navigation ID under the control of the control unit 19, for example. This transmission data is transmitted from the communication terminal device 50 to the wireless telephone communication network 300, and is received by the application server 303 in the wireless telephone communication network 300.
Then, the application server 303 transmits the received update data request and the navigation ID to the service server 500 via the Internet 400.

Note that the application server 303 performs authentication processing at the stage of receiving the request, and whether the navigation system 1 that sent the request is owned by a user who has a legitimate right to receive this service. It is preferable to determine whether or not.
Therefore, in order to perform the authentication process under this system configuration, the navigation system 1 may transmit a password together with the navigation ID. The application server 303 registers not only the password registered corresponding to the mobile phone 200 but also the password corresponding to the navigation system as the data for each user in the user database 410, and receives the request. In some cases, referring to the user database 410, the password corresponding to the navigation system 1 received together with the request and the navigation ID may be collated.

In response to this request, the service server that has received the request and the navigation ID reads the update data of the map information stored in the storage unit 501 as the service data 512. Then, the read update data is transmitted to the application server 303 in the wireless telephone communication network 300 via the Internet 400 together with the received navigation ID. The application server 303 transmits and outputs the received update data with the received navigation ID (phone number) as the transmission destination. Thus, the update data is received in the navigation system 1 that has requested the update data.
On the navigation system 1 side, the received update data is stored. Thereafter, by using this update data, the contents of the update data can be reflected as navigation operations such as displaying the current position on the map and displaying various guide information.

Moreover, although it is not a service with a merit for a user, the following things can also be performed as a response | compatibility with respect to the user after the purchase of the navigation system 1. FIG.
In this case, as the service server 500, when the user purchases the navigation system 1 by installment payment, a database of the payment status is stored. And if it is found from the contents of the above-mentioned database that the user's payment is over a certain limit, the service server 500 side, for example, “Please pay the price. Confirmation of the price payment. I will stop using the navigation system until I can get off. "And send control information. In the navigation system 1 that has received this, the message having the above-described contents is displayed on the display screen 3a, and thereafter, the navigation system 1 itself stops its operation.
Further, as described above, the navigation system 1 according to the present embodiment can be purchased as a single unit, but can also be purchased in combination with this when purchasing automobile insurance. In the case of purchasing in combination, services such as further discounting the amount of both or discounting interest payments on installments are provided. Then, when the purchase by the combination is made in this way, if the payment is delayed as described above, the insurance contract is also stopped together with the stop of the use of the navigation system 1, and as a message Will be notified that insurance contracts will also be suspended.

In this way, in the present embodiment, various services can be provided by the communication between the navigation system 1 and the mobile phone 200 or the service server 500.
For example, although it is known that a conventional navigation system can be connected to the Internet, the navigation system in this case is one of a large number of unspecified terminal devices on the Internet. It is impossible to designate and access a specific navigation system 1. Therefore, if the user of the navigation system 1 tries to receive service provision, the user needs to access the service server 500 from the navigation system 1 after grasping the URL of the service server 500 or the like. . In principle, the service server 500 is premised on receiving access from an unspecified number of terminals as the navigation system 1, and therefore, for example, services provided for each user can be properly used as necessary. First, it was necessary to provide various general-purpose services and select from these services by accessing from the navigation system 1 side. In other words, the service cannot be fully enjoyed unless the user actively performs operations such as operations to access the service.

  On the other hand, in the present embodiment, for example, in the service server 500 or the application server 303, the navigation ID assigned to each navigation system 1 is held as a user database, and this navigation ID is designated. Thus, the specific navigation system 1 can be accessed. In other words, according to the present embodiment, a service having an appropriate content can be actively provided to the navigation system 1 by an access from the server side, for example, at an appropriate opportunity.

3. Processing Operation Example Next, processing operations when realizing some services selected from the various services exemplified above will be described.
First, the processing operation for realizing the upgrade service of the navigation system 1 provided by the service server 500 will be described with reference to the flowchart of FIG. In this figure, processes executed in each of the service server 500, the application server 303, and the navigation system 1 are shown in parallel. Further, the processing as the service server 500 is executed by the control unit 503, the processing as the application server 303 is executed by the control unit 404, and the processing as the navigation system 1 is executed by the control unit 19.

  For example, if the manufacturer instructs the service server 500 that the version of the navigation system 1 should be upgraded, the control unit 503 of the service server 500 performs the process in step S101 or An access request to a specific navigation system 1 is made. At this time, a navigation ID of the navigation system 1 to be accessed is transmitted together with the access request. For example, the navigation ID is searched from the user information in the user database 501 for the user who owns the device of the navigation system 1 that needs to be upgraded, and the navigation ID associated with the searched user information is read out. Get by that.

The above access request is transmitted from the Internet 400 to the application server 303 via the gateway 304. When the application server 303 receives this access request in step S201, the process proceeds to step S202. To do.
In step S202, a version request asking for the current system version is transmitted to the navigation system 1 having the received navigation ID. In this case, for example, a telephone number as a navigation ID is designated as a transmission destination, and version request data is transmitted via the relay station 302 and the base station 301.

The communication terminal device 50 of the navigation system 1 having a specific navigation ID receives the version request transmitted as described above and transfers it to the control unit 19 in the navigation main body 2. Thereby, as a process of step S301, the control unit 19 determines that a version request has been received.
The control unit 19 that has received the version request notifies the current version through the process of step S302. That is, when the current version of the system is identified, the identified version number is transmitted from the communication terminal device 50 to the application server 303 as a response. Note that this response also stores his or her navigation ID.

  When the application server 303 receives the above-described response in step S203, the process proceeds to step S204 to notify the service server 500 of the version. That is, the version number and navigation ID stored in the received response are extracted, and these pieces of information are transmitted to the service server 500.

When the service server 500 receives the notification of the version number from the application server 303 in step S103, the service server 500 determines in step S103 whether upgrade is necessary based on the notified version number. For example, if the notified version number is equal to or higher than the version number of the current updater, the version update is not required and a negative result is obtained. The result will be obtained.
If a negative result is obtained here, communication (access) to the navigation system 1 having this navigation ID is not executed any more, but if a positive result is obtained, the processing of the next step S104 is performed. The upgrade message and the updater are transmitted to the application server 303 together with the navigation ID. These upgrade messages and updater are obtained by reading out the data stored as the service data 512 in the storage unit 501 of the service server 500.

  The application server 303 receives the upgrade message, updater, and navigation ID in step S205. In subsequent step S206, the upgrade message and the update data are transmitted to the navigation system 1 of the received navigation ID.

In the navigation system 1, the upgrade message and updater are received by the wireless terminal device 50 and transferred to the control unit 19 of the navigation main body 2. As a result, as shown in step S303, it is determined that the upgrade message and updater have been received, and the process proceeds to step S304.
In step S304, display image data is generated based on the data content of the received upgrade message, for example, “Car navigation version upgrade has been released. Download and update”, and so on. The user is notified that an operation to update the system version is executed. It should be noted that the character content as the message as described above is included in the content of the received upgrade message.
Then, in the next step S305, the control unit 19 of the navigation main body unit 2 rewrites necessary system data such as an execution program and preset data written in the ROM 11 by using the received update data. Execute the update.

Subsequently, the user uses the mobile phone 200 to make an inquiry about whether or not his / her car is locked. If the user does not have the key, the user uses the mobile phone 200 again to lock the car. The processing operation for controlling the operation will be described with reference to FIGS.
In these drawings, processes executed in each of the mobile phone 200, the application server 303, and the navigation system 1 are shown in parallel. The processing as the mobile phone 200 is executed by the system controller 208, the processing as the application server 303 is executed by the control unit 404, and the processing as the navigation system 1 is executed by the control unit 19.

First, FIG. 8 shows a processing operation for making an inquiry about whether or not the car is locked from the mobile phone 200 to the car.
For example, when the user performs a predetermined operation on the mobile phone 200, a process for transmitting a security request together with the terminal ID shown as step S401 is executed. For this purpose, for example, first, the mobile phone 200 communicates to access a server of a security system that is operated in the application server 303. The server then requests a security inquiry about a car owned by the server. At this time, in order to prevent misuse by a user other than the user himself / herself, input of a password registered in advance by the user is required.

In the application server 303 (security system server) that has received the above-described security request, terminal ID, and password in step S501, as a process in step S502, the user database 410 is first referred to, and the password and the terminal ID are verified. The authentication process is executed by performing That is, it is confirmed that the user who transmitted the security request, the terminal ID, and the password is a legitimate user. If authentication is not obtained at this time, the subsequent processing is stopped.
If the authentication is properly obtained, in the next step S503, the user database 410 is searched for the navigation ID associated with the authenticated terminal ID and password. In subsequent step S504, a security request is transmitted to the navigation system 1 having the acquired navigation ID (phone number).

The communication terminal device 50 of the navigation system 1 receives the above security request and transfers it to the control unit 19 of the navigation main body 2. Thereby, by the process shown as step S601, the control part 19 discriminate | determines that the security request was received, and progresses to step S602.
In step S602, a security check with a predetermined content is executed. In other words, data with a predetermined content indicating the current situation that the security system unit 41 is monitoring is fetched. Here, at least information on whether or not the car is locked is acquired. By the processing in step S603, data indicating the result of the security check is transmitted as a response to the application server 303 together with the navigation ID of the navigation system 1.

When the application server 303 receives a response including the security check result data and the navigation ID in step S505, the process proceeds to step S506.
In step S506, the user database 410 is referenced to search for a mobile ID associated with the received navigation ID. In the next step S507, the security check result data is transmitted to the mobile phone 200 having the specified mobile ID (phone number). At this time, it is assumed that the result data of the security check to be transmitted to the mobile phone 200 is converted into a format that allows the mobile phone 200 to display and output characters. For example, if the mobile phone 200 has an Internet e-mail function, it may be possible to convert it to an e-mail format and send it to a mail address associated with the mobile ID.

  In the mobile phone 200, when it is determined in step S402 that the transmitted security check result data has arrived, this is received and stored in the ROM 217, for example, in the next step S403. Then, for example, after this, when the user performs a predetermined operation, the result of the security check can be displayed on the LCD display unit 209 by characters or the like by the processing in step S404.

  For example, when the user knows that the car is not locked from the result of the security check displayed on the LCD display unit 209, the car is controlled by remote control from the mobile phone 200 as described above. It is possible to lock the key. The process for this is shown in FIG.

  Here, for example, according to a predetermined operation of the user, the application server 303 is accessed using the Internet connection function of the mobile phone 200 by the process of step S701. Then, key lock instruction information for instructing to lock the car is transmitted together with the portable ID and the password.

When the application server 303 receives the key lock instruction information, the mobile ID, and the password by the process in step S801, first, the authentication process is executed by the process in step S802. This authentication process is the same as the authentication process in step S502 of FIG. If a proper authentication result is obtained, the process proceeds to step S803.
In step S803, the user database 410 is referenced to search for a navigation ID associated with the mobile ID. In the next step S804, a key lock command is transmitted to the navigation system 1 having the searched navigation ID.

In the navigation system 1 having the navigation ID described above, it is determined that the key lock command has been received by the processing in step S901. And in response to the received key lock command, the control unit 19 controls the lock control unit 44 of the security system unit 41 to lock the car.
Although the processing operation is not shown in this figure, for example, after the key lock control in step S902 is executed, the operation of locking the car from the navigation system 1 to the mobile phone 200 is performed. It is preferable to transmit security data indicating that the key lock operation has been completed so as to confirm that the key lock operation according to the user's instruction has been executed normally.

Next, the processing operation related to the map information update data providing service will be described with reference to FIG.
In this figure, processes executed in each of the navigation system 1, the application server 303, and the service server 500 are shown in parallel. The processing as the navigation system 1 is executed by the control unit 19, the processing as the application server 303 is executed by the control unit 404, and the processing as the service server 500 is executed by the control unit 503.

  For example, as described above in the service provision form example, if an operation for downloading update data of map information is performed on the navigation system 1 by the user, the map information is displayed as shown in step S11. The process for transmitting the navigation ID and password is executed for the update data request.

In the application server 303 that has received the update data request, the navigation ID, and the password in step S21, as a process in the next step S22, the registered password, navigation ID, and the like are referred to by referring to the user database 410. Authentication processing is executed by performing verification. That is, it is confirmed whether or not the user who transmitted the update data request is a legitimate user. In this case as well, the subsequent processing is stopped if authentication is not obtained.
If the authentication is properly obtained, the request and the navigation ID received in the previous step S21 are transmitted to the service server 500 in the next step S23.

  In the service server 500, when the request and the navigation ID transmitted from the application server 303 are received as the process of step S31, the map information stored in the storage unit 501 as the service data 512 is received in the next step S32. Read the update data file.

  In addition, this update data should just be made into the difference data with respect to the data as map information before an update as mentioned above, for example. Here, all the update data files may be read out. However, for example, this update data is purchased as a product, and the price changes depending on the number of areas designated by the user, for example. It is also possible to set as follows. Therefore, in such a case, the request may include information specifying the update data file to be downloaded, and only the specified update data file may be read.

  When the update data file is read as described above, subsequently, the update data file read by the process of step S33 is sent to the application server 303 together with the navigation ID previously received with the request in step S31. To be sent.

In the application server 303, the update data file and the navigation ID transmitted from the service server 500 as described above are received by the processing in step S24.
In the next step S25, the update data file received in step S24 is transmitted to the telephone number indicated by the navigation ID received in step S24. That is, the update data is transferred to the navigation system 1 that has requested download of the update data.

  The update data file transmitted in this way is received by the navigation system 1 by the process of step S12. In the next step S13, the received update data file is written and stored in, for example, the DRAM 13, the memory 12, or the storage unit 45.

Here, for example, how the update data file stored as described above is used can be considered as follows.
For example, the navigation system 1 basically reads the map information recorded in the recording medium 9 and displays various navigation information to the user, including the current position display on the map, based on the map information. I am doing so.
Therefore, when the recording medium 9 in which the map information is stored can be rewritten or additionally written, the update data is written to the recording medium. As a result, when navigation is performed using map information read from the recording medium 9 thereafter, the update data is also used, and for example, a navigation operation reflecting the content of the update data is obtained. become.
When the recording medium 9 is not rewritable, for example, the received update data is stored in the memory 12 or the storage unit 45 that maintains the stored contents even when the power is turned off. When display using map information is performed, for example, the update data stored in the memory 12 or the storage unit 45 is read out and combined with the map information read out from the recording medium 9 so that the update data is stored. Form reflected map information. Then, navigation operation is performed using this map information.

  As described above, the update data providing service may be charged or free, but if it is charged, the download data transmitted from the navigation system 1 can be downloaded. When the request is received on the server side, for example, a settlement process corresponding to the payment method designated by the user may be performed.

4). Service provision system (second example)
4-1. Overall Configuration Next, a service providing system as a second example of the embodiment will be described.
FIG. 11 shows an example of a service providing system as a second example.
As shown in this figure, the second example adopts a configuration in which a personal computer 700 and an authentication server 800 are added to the system configuration of the first example shown in FIG. . Therefore, in the description of FIG. 11, the difference between these additional portions and the like will be mainly described, and the same portions as those in FIG. I will do it.

The personal computer 700 in this case is assumed to be owned by the same user as the owner (user) of the navigation system 1 and the mobile phone 200, and is assumed to be installed indoors such as a home or a company. The Then, connection to the Internet is made via the access communication network 600.
Here, the personal computer 700 according to the present embodiment is installed in an environment such that it does not move on a daily basis indoors. Therefore, for example, the personal computer 700 is connected to the access communication network 600. A connector for communication is also in a state of being fixedly connected without being exchanged on a daily basis. In other words, as the use environment of the personal computer 700 of the present embodiment, for example, when using a portable personal computer such as a so-called laptop computer, the access communication network 600 It is assumed that there are no different connectors and regions to be connected.

As described above, the personal computer 700 is connected to the Internet via the access communication network 600. This access communication network 600 is connected to the telephone by, for example, the personal computer 700 dialing up from a modem. If the Internet is accessed from an ISP (Internet Service Provider) via a line, the access communication network 600 is a general telephone line.
Of course, the access communication network 600 according to the present embodiment is not limited to the above-described general telephone line. For example, ISDN (Integrated Services Digital Network), xDSL, CATV, and wireless communication network including ADSL (Asymmetric Digital Subscriber Line) using the high frequency band of the telephone line for communication can be used. .

When the personal computer 700 accesses the navigation system 1 mounted on the automobile 100 in order to obtain the current position information of the automobile 100, for example, as will be described later, this authentication server 800 accesses the navigation system 1 appropriately. It is provided to authenticate whether or not it is a thing. As a result of this authentication server 800 functioning, as a result, for example, by so-called impersonation, a personal computer that is not properly registered obtains the current position information from the automobile 100, thereby preventing an illegal act.
The internal configuration and operation of the authentication server 800 will be described later.

4-2. Internal Configuration of Personal Computer FIG. 12 shows an internal configuration example of the personal computer 700.
A personal computer 700 shown in this figure includes a network interface 709 for performing communication via the Internet 400. The network interface 709 is responsible for communication between the access communication network 600 and the personal computer 700, whereby the personal computer 700 is connected to the Internet 400 via the access communication network 600.

The CPU 701 executes various processes according to, for example, various application programs installed in the hard disk drive and programs stored in the ROM 702. In the present embodiment, for example, a program for controlling the network interface 709 with respect to the ROM 702 is also stored in order to enable transmission / reception of various data according to TCP / IP which is a communication protocol related to the Internet. become. In other words, the personal computer 113 is provided with a set (hardware and software) capable of data transmission / reception using the Internet.
The RAM 703 appropriately stores data, programs, and the like necessary for the CPU 701 to execute various processes.

The input / output interface 704 is connected to a keyboard 705 and a mouse 706, and outputs an operation signal supplied from these to the CPU 701. The input / output interface 704 is connected to a hard disk drive 707 having a hard disk as a storage medium. The CPU 701 can record or read data, programs, and the like on the hard disk of the hard disk drive 707 via the input / output interface 704. In this case, the input / output interface 704 is further connected to a display monitor 708 for displaying an image.
The internal bus 710 is configured by, for example, a PCI (Peripheral Component Interconnect), a local bus, or the like, and interconnects the functional circuit units inside.

4-3. Internal Configuration of Authentication Server Next, an internal configuration example of the authentication server 800 will be described with reference to FIG.
The authentication server 800 shown in this figure includes a storage unit 801, a network interface 802, and a control unit 803.
In the case of the authentication server 800, the storage unit 801 stores information necessary for executing an authentication process described later. Here, an authentication user database 810 and an execution application 811 are shown as data stored in the storage unit 801.

For example, as shown in the lower part of the figure, the authentication user database 810 stores user information, a mobile ID, a navigation ID, a PC-ID, a content ID, and a PC password in association with each other. .
The user information is information relating to a user who owns the navigation system 1, the mobile phone 200, and the personal computer 700 as a set. For example, in the case of the system of the present embodiment, the user information is stored in the service server 500 (or application server 303). The content may be the same as the user information that forms the stored user database 510 (410).

  The mobile ID stores the same data as the mobile ID written in the mobile phone owned by the user specified by the user ID. Similarly, the navigation ID stores the same navigation ID data assigned to the navigation system 1 owned by the user. The navigation ID may be a telephone number assigned to the wireless terminal device 50. That is, in this case, the mobile ID and the navigation ID need only store the same information as the information stored in the user database structure described in FIG.

The PC-ID is an ID for identifying the personal computer 700 that is owned by the user specified by the user ID. The present embodiment is characterized by the structure of the PC-ID, which will be described later as an example of registration of the PC-ID.
The service ID is an ID for identifying a service to be processed correspondingly by the authentication server 800.
In constructing this authentication user database 810, it is necessary to register each of the above-mentioned information corresponding to each user, which will be described later.

In this case, the execution application 811 includes various application programs corresponding to various operations to be executed by the authentication server 800.
The network interface 802 is provided as an interface unit for connecting to the Internet 400.
The control unit 803 executes various control processes according to the program contents as the execution application 811.

4-4. Example of Service Providing The system configuration shown in FIG. 11 is fixed to, for example, indoors in addition to the navigation system 1 and the mobile phone 200 as devices connected to the Internet 400 in order to receive service provision. Therefore, it can be said that the personal computer 700 that is installed automatically can be used.
In such a system, for example, a service can be provided in which the navigation system 1 transmits current position information indicating the current position of the automobile 100 to the personal computer 700.

The service contents are briefly described as follows.
Here, it is assumed that the user who is using the personal computer 700 wants to know the current position of the automobile 100 on which the navigation system 1 owned by the user is currently installed. In this case, the user starts a web browser application on the personal computer 700 and performs a predetermined operation to access the current location notification service website. The website of the current location notification service is the website uploaded by the authentication server 800. That is, the personal computer 700 accesses the authentication server 800 when the user accesses the website of the current location notification service.

When accessing the authentication server 800 as described above, the user transmits a request for notification of current position information. In addition to the current position information notification request, the authentication server 800 also transmits necessary authentication information to be used for authentication.
Note that what the authentication information is will be described later.
The authentication information used for authentication by the authentication server includes a PC-ID that is unique to the personal computer 700 that transmitted the request. This PC-ID is not generated and transmitted by the personal computer 700. Instead, in the access communication network 600 to which the personal computer 700 is connected, for example, a part that functions as an application server is generated when the personal computer 700 accesses the authentication server 800. The generation of the PC-ID and registration in the user database 810 will be described later.

In the authentication server 800, referring to the authentication information transmitted together with the current location information notification request and the user database 810 as described above, the personal computer 700 that transmitted this request is properly registered. Authentication processing is performed as to whether or not the device is a device. If a normal authentication result is obtained, this request is transferred from the Internet 400 to the navigation system 1 that is owned by the user via the wireless telephone communication network 300.
In addition, when a regular authentication result is not obtained, the request is not transferred to the navigation system 1.

  In the navigation system 1 that has received the request, vehicle position information indicating the current vehicle position is generated and transmitted from the radio telephone communication network 300 to the authentication server 800 via the Internet 400. The authentication server 800 transmits the transmitted vehicle position information to the personal computer 700. In the personal computer 700, the received vehicle position information is reproduced and output by a Web browser. As a result, the current vehicle position information is displayed on the display monitor 708 of the personal computer 700.

4-5. Construction of Authentication User Database As can be seen from the operation of the authentication server 800 in the above description, when the user enjoys this service, the information related to the user who wants to enjoy the service is the authentication server 800. The user database 810 needs to be registered.
There are several possible procedures for this registration. One is that when the user wants to enjoy this service, the user causes the personal computer 700 to access the authentication server 800, and a predetermined procedure is performed. It can be considered that registration is performed by performing an operation for registration.
That is, the user operates the personal computer 700 to access, for example, a registration Web page in the authentication server 800. On this Web page, necessary information items for one user required to construct the authentication user database 810 shown in FIG. 13 can be input. That is, personal information such as name and address as “user information”, “mobile ID (phone number)” of the mobile phone 200 owned by the user, and “navigation ID (phone) of the navigation system 1 also owned by the user” Number) ”and the service content to be enjoyed corresponding to“ service ID ”(in this case, the current location notification service) are input. For example, in the authentication server 800, it can be considered that authentication other than the current location notification service is also performed for authentication. However, in such a case, the service ID indicates that the user provides the service. When requested, it can be used to identify what the service is.

  Further, for example, regarding the current location notification service as the present embodiment, since the mobile phone 200 is not used to enjoy this service, the mobile ID is not necessarily used as the information element of the authentication user database 810. do not have to. However, if the authentication server 800 also performs authentication corresponding to services other than the current location notification service, and the other service uses the mobile phone 200, the mobile ID is required. Is.

Further, according to FIG. 13, it is necessary to register a PC-ID in addition to the “user information”, “mobile ID (phone number)”, “navigation ID (phone number)”, and “service ID”. Become.
With regard to this PC-ID, for example, a device ID consisting of information such as a manufacturer code for identifying a device as a personal computer and a manufacturing number is generated in the personal computer 700, and this is transmitted as the PC-ID together with the above information. This is generally considered. The above manufacturer code and serial number information is stored in, for example, a ROM in the personal computer 700, for example, during the manufacturing process. The personal computer 700 generates a device ID based on this information. It's easy.

However, when information stored in the personal computer 700 in advance such as a manufacturer code and a serial number is used as a device ID, it can be easily falsified by a malicious user and so-called “spoofing” can be performed. It has sex.
Specifically, taking the current location notification service of the present embodiment as an example, for example, although there is only one personal computer 700 that is properly registered, other personal computers may be registered personal computers 700. There is a possibility that an illegal act of rewriting the device ID of the computer and accessing the authentication server 800 is performed.
For example, in the system configuration as the first example, the navigation system 1 and the mobile phone 200 are both connected to the Internet via the radio telephone communication network 300. Since the wireless telephone communication network 300 performs management based on information such as a telephone number, there is no problem of impersonation as long as access is made using this telephone number. However, if the personal computer 700 is added to the system configuration as in the system of the second example, the personal computer 700 does not access the wireless telephone communication network 300, for example, any telephone line or the like. The Internet is accessed via the access communication network 600. In such a case, the above-mentioned impersonation problem occurs, and it is necessary to solve this problem.

  Therefore, in the present embodiment, by generating a PC-ID and registering it in the authentication server as follows, it is impossible to enjoy an unauthorized service by impersonating the device ID. Here, three examples are given according to the type of communication network actually used as the access communication network 600.

FIG. 14 schematically shows a first example of the PC-ID registration procedure. In this first example, the access communication network 600 is a general telephone line or an ISDN line.
When the access communication network 600 is a general telephone line or ISDN line, so-called dial-up is performed in order for the personal computer 700 to be connected to the Internet. That is, although not shown here, a modem, TA (Terminal Adapter), or DSU (Digital Service Unit) provided on the personal computer 700 side is actually used as a general telephone line or ISDN network in the access communication network 600. Dialing and connecting to the telephone office 601 which is the equipment to be arranged.

  Here, it should be noted that dialing up to the telephone station 601 means that the telephone numbers assigned to the dialing up and the telephone lines assigned to the ISDN line are uniquely determined. That is. Since the telephone number is managed by the telephone station 601, it can be said that the telephone number is information that cannot be falsified by the user of the personal computer 700. Therefore, in this embodiment, this telephone number is used when generating the PC-ID. And generation and registration of PC-ID using this telephone number can be performed in the following procedures.

First, as procedure 1, the personal computer 700 transmits a device ID toward the authentication server 800. The device ID is actually transmitted together with the above-described information of “user information”, “mobile ID (phone number)”, “navigation ID (phone number)”, and “service ID”. You can do it. In addition, this device ID may be formed by a manufacturer code and a serial number as described above, for example.
Then, in the telephone station 601 in the access communication network 600, as procedure 2, based on the transmitted device ID and information on the telephone number of the telephone line (ISDN line) used for dial-up, A PC-ID is generated. In this case, how to generate the PC-ID using the device ID and the telephone number information is not particularly limited because it can be considered variously. For example, the simplest device ID is the device ID. It is conceivable to form a PC-ID by concatenating data values as telephone number information. Further, it is conceivable that a data value by a predetermined number of bits is obtained by performing a calculation by a predetermined function using a data value as the device ID and telephone number information, and this data value is used as a PC-ID.

Since the PC-ID generated in this way is created by the device ID and the telephone number, it is unique information for each personal computer 700. In addition, since the telephone number is also an element of the PC-ID, for example, even if the device ID is simply rewritten, the telephone number is not rewritten, so that the same PC-ID is not obtained. Further, since the telephone number is managed on the telephone station 601 side and the PC-ID is created on the telephone station 601 side, the user of the personal computer cannot rewrite the telephone number part. Impossible. Therefore, it is impossible to perform so-called impersonation for a personal computer.
Then, the telephone station 601 transmits the PC-ID generated in this way to the authentication server 800 via the Internet.

  In the authentication server 800 that has received this PC-ID, as shown in step 3, the received PC-ID is used together with other information (user information, portable ID, navigation ID, and service ID) as an authentication user database 810. To be registered.

A second example of the PC-ID registration procedure is shown in FIG. In the second example, the access communication network 600 is a communication network that can be always connected, such as ADSL.
In the case of such a communication network, for example, a telephone station 601 that is a facility in the access communication network 600 is provided with a port unit such as a splitter that branches a telephone line into a general telephone line and an Internet route. In this figure, such port portions are shown as connection ports 602, 602.

  For example, in the telephone station 601, when the subscriber subscribes to ADSL, the connection port 602 is constructed to connect to the subscriber's telephone line. Accordingly, it can be said that the connection port 602 is managed by the telephone office 601 side and the telephone line to be connected is also fixed.

  Therefore, in the present embodiment, for example, the telephone station 601 assigns and manages an identifier (port ID) for each connection port 602. Since this port ID is unique for each connection port, the correspondence between the personal computer 700 connected to the telephone office 601 and this port ID is fixed, like the telephone number in the first example. . Further, since the port ID is managed on the telephone office 601 side, for example, a user of a personal computer cannot tamper with this part.

  Therefore, as a second example, a PC-ID is generated using a port ID. And generation and registration of PC-ID using this port ID are performed in the following procedures, for example.

First, as procedure 1, the personal computer 700 transmits a device ID to the authentication server 800. Even in this case, the device ID is formed by the manufacturer code and the serial number. In addition, the device ID is actually transmitted together with each information of “user information”, “mobile ID (phone number)”, “navigation ID (phone number)”, and “service ID”.
Then, as procedure 2, the telephone station 601 in the access communication network 600 generates a PC-ID using the transmitted device ID and the port number information of the connection port of the telephone line as ADSL. . Then, the telephone station 601 transmits the PC-ID generated in this way to the authentication server 800 via the Internet.
Then, as procedure 3, the authentication server 800 that has received this PC-ID registers it in the authentication user database 810 along with other information (user information, mobile ID, navigation ID, and service ID).

FIG. 16 shows a PC-ID registration procedure as a third example. In this third example, the access communication network 600 is provided with equipment as a dedicated line 610, and a personal computer 700 is always connected to the dedicated line 610.
In such a case, the personal computer 700 is connected to a router 611 provided on the dedicated line 610, and connection from the router 611 to the Internet 400 is performed. In this case, since the personal computer 700 is always connected to the router 611, the path between the personal computer 700 and the router 611 is fixed. Further, the management of the router 611 is also performed by the operator on the dedicated line 610 side, and it is assumed that the user on the personal computer 700 side cannot tamper with the information regarding the router 611.
Therefore, as a third example, a PC-ID is formed using the device ID of the personal computer 700 and information unique to the router 611. In this case, the router address assigned to the router 611 is used as information unique to the router 611.

The PC-ID registration procedure as the third example is as follows.
First, as procedure 1, the personal computer 700 transmits a device ID to the authentication server 800. Even in this case, the transmission of the device ID is actually performed together with the information of “user information”, “mobile ID (phone number)”, “navigation ID (phone number)”, and “service ID”. Is done.
However, as the device ID in this case, as in the case of the first example and the second example above, the information consisting of the manufacturer code and the serial number may be used, but it is always connected. Assuming that, for example, even if it is based on DHCP (Dynamic Host Configuration Protocol), after the IP address is first assigned, the IP address does not change. Therefore, in this case, an IP address may be used as the device ID.

  As the next procedure 2, a PC-ID is generated on the dedicated line 610 in the access communication network 600 using the transmitted device ID and the router address of the router 611 to which the personal computer 700 is connected. Then, the telephone station 601 transmits the PC-ID generated in this way to the authentication server 800 via the Internet. Then, the authentication server 800 that has received the PC-ID registers the received PC-ID in the authentication user database 810 along with other information (user information, mobile ID, navigation ID, and service ID) as step 3. .

  Note that the IP address is set as the device ID. In IPv4, the IP address assigned by the DHCP server changes every time the connection is made. In IPv6, the connection is not always connected. Both IP addresses can be assigned fixedly. Therefore, if communication is performed with the Internet according to IPv6, the device ID can be used as the IP address in the first and second examples described above.

Thus, in the first to third examples, the PC-ID is formed using not only the device ID of the personal computer 700 but also the telephone number, the port ID of the connection port, or the router address. I have to.
Here, the telephone number, the port ID of the connection port, and the router address information indicate the communication path (access path) until the personal computer 700 connects to the access communication network 600 on the path between the personal computer 700 and the Internet. It can be said that it is information to identify.
As can be understood from the above description, if it is assumed that the personal computer 700 is fixedly installed indoors, for example, the communication path to connect to the access communication network 600 is personal. There is a one-to-one correspondence between the computer 700 and the communication path. Therefore, even if the information specifying the communication path and the device ID are combined, there is no problem in forming a PC-ID unique to the personal computer 700. Also, as described in the previous explanation, each piece of information (telephone number, port ID of connection port, router address) for specifying the communication path is managed by the facility operating the access communication network 600. It is assumed that the user of the malicious personal computer 700 cannot tamper with it. Therefore, the user of the personal computer 700 cannot falsify the PC-ID generated using this information. In the present embodiment, the PC-ID is not generated on the personal computer side but on the equipment side of the access communication network 600 that is a relay point. Remarkably low.
In other words, the PC-ID of the present embodiment is information that can identify a personal computer and can prevent impersonation due to tampering. Accordingly, as described above, it is possible to prevent provision of services using the personal computer 700 by impersonation.
In the present invention, it is only necessary to be information that can specify the communication network (access route) to which the personal computer 700 is initially connected, and the PC-ID generation in the registration procedure illustrated by FIGS. In addition to the examples, it is possible to generate a PC-ID conforming to the present invention, and the type of the access communication network 600 is not limited to that illustrated in FIGS.

4-6. Processing Operation Example Next, based on the above description, refer to the flowchart of FIG. 17 for the processing operation for realizing the vehicle current position notification service, which is assumed to be performed by the service providing system as the second example. To explain. Note that the outline of the operation of the present position notification service for automobiles as the present embodiment is as described above.
In this figure, processes executed in each of the personal computer 700, the authentication server 800, and the navigation system 1 are shown in parallel. The processing as the personal computer 700 is executed by the CPU 701, the processing as the authentication server 800 is executed by the control unit 803, and the processing as the navigation system 1 is executed by the control unit 19.

  When the personal computer 700 is notified of the current position of the vehicle on which the navigation system 1 is installed, as described above, for example, a web browser application is started on the personal computer 700 and the current status in the authentication server 800 is determined. A location notification service Web site is accessed. Then, by performing a predetermined operation on the browser screen displayed at this time, the personal computer 700 transmits a current position notification request. This is the process of step S41 in FIG.

When transmitting the current location notification request in step S41, the user information, the device ID, and the service ID are transmitted together.
For example, an input box for inputting various items required for the request is displayed on the browser screen of the current position notification service. The user information is created by the CPU 701 as an ID for identifying the user based on personal information such as an address and name input in the input box.
Further, if the device ID is made up of, for example, a manufacturer code and a manufacturing number, the CPU 701 creates the device ID based on information on the manufacturer code and the manufacturing number read from the ROM 702, for example. If the device ID is an IP address, for example, the device ID is created using the IP address held in the RAM 703.
In addition, the service ID is stored in the data structure as the current position notification request, for example, as an ID indicating that this request corresponds to the current position notification service.

  The current location notification request transmitted as described above is first routed in the access communication network 600 and transferred to the authentication server 800 via the Internet 400 as described with reference to FIGS. Will be. At this time, the equipment of the access communication network 600 receives the received device ID and the route identification information (telephone number, port ID, router address, etc.) that is managed and held by itself. Use it to create a PC-ID. Accordingly, the PC-ID, user information, and service ID are transmitted to the authentication server 800 together with the current position notification request.

  The authentication server 800 receives the current location notification request, user information, PC-ID, and service ID transmitted as described above in step S51. Then, in the next step S52, authentication processing is executed by comparing and referring to the received user information, PC-ID, service ID, and the like and the user database for authentication 810.

  In the next step S53, as a result of the authentication process in the above step S52, it is determined whether or not authentication as a legitimate user has been established. If a negative result is obtained, As shown in S55, the process corresponding to the reception of the current request is rejected. That is, thereafter, for example, in response to the received request, processing for transmitting the current position information to the personal computer 700 is not performed. Although not shown in the figure, for example, as the process of step S55, it is preferable to notify the personal computer 700 that, for example, authentication has not been established.

On the other hand, if an affirmative result is obtained in step S53 that authentication has been established, the current position notification request received this time is transmitted to the appropriate navigation system 1 as processing in step S54. Do.
At this time, the authentication user database 810 is searched for the navigation information stored in association with the user information, PC-ID, and service ID received together with the current request. Then, the searched navigation ID (telephone number) is designated and a current position notification request is transmitted to the radio telephone communication network 300. As a result, the current position notification request is correctly transmitted to the navigation system 1 owned and registered by the user who owns the personal computer 700.

For example, in the navigation system 1 mounted on the automobile 100, the current position notification request is received by the process of step S61.
Here, the navigation system 1 of the present embodiment stores a program corresponding to the current location notification service. When the received information is a current position notification request, the program uses the current position information measured by the positioning unit 4 and the map information read from the recording medium 9 or the like to obtain the current position information. An operation of creating and accessing the authentication server 800 to perform transmission is executed. Note that as the map information used to generate the current position information, for example, if there is update data acquired as described above, this update data is also used. Then, the processes of steps S62 to S64 described below are executed according to this program.

In step S62, current position information is created.
As described above, the current position information created here is, for example, in a format such as HTML or XML that can be displayed by a Web browser. It is assumed that it has data contents that can be displayed. Note that it is also conceivable to generate image data in a predetermined format such as JPEG, JIF, and bitmap.

In the next step S63, the navigation system 1 executes a control process for accessing the authentication server 800. For this reason, for example, in the navigation system 1, it is assumed that the URL of the authentication server 800 is held in, for example, the memory 12, and the control unit 19 communicates with the communication terminal 47 from the communication interface 47 so that the URL is accessed. An access request is transmitted via the device 50.
Then, if a connection with the authentication server 800 is established in response to this access request, the current position information generated in the previous step S62 is transmitted to the authentication server 800 by the process of the next step S64. To do.

  When the authentication server 800 receives the current position information transmitted as described above as the process of step S56, the authentication server 800 transfers the current position information to the requesting personal computer 700.

The personal computer 700 that has made the current location notification request is connected to the authentication server 800 as described above, and an appropriate Web page is displayed and output by the browser. Under this state, the transferred current position information is received by the process of step S42.
The current position information received in this way takes the form of a file such as HTML or XML as described above. In the personal computer 700, the current position information is reproduced by the process of step S43, thereby displaying the current position as a browser image.
In the above processing operation, the current position information is transmitted from the navigation system 1 to the personal computer 700 via the authentication server 800. This is to facilitate transmission of information from the navigation system 1 by relaying the authentication server 800 using the connection of the personal computer 700 with the authentication server 800. However, since it is not necessary to execute the authentication process at this stage, the navigation system 1 can be configured to directly transmit to the personal computer 700.

  As an authentication server 800, for example, as a matter of course, a plurality of devices functioning as the authentication server 800 are distributed on the Internet, for example, in order to reduce processing load, not as a single device. It is also possible to use a configuration provided by

In addition, as a configuration for preventing fraud, the following configuration may be supplementarily added.
For example, in the service providing system according to the present embodiment, the Internet connection of each device (navigation system, mobile phone, personal computer, etc.) registered as a user to use for providing the service is specified as one specific communication company. (Telephone company, etc.) For example, a monitoring server is provided in a communication network covered by this communication company. The monitoring server monitors whether or not a line within a certain range covered by this communication company is used for communication between the devices registered by the user. Then, if the device registered by the user enters a situation where communication is performed by entering from a line outside the fixed range covered by the telecommunications company, a warning is given or an unauthorized service is provided. When it is assumed that the line is being used, the communication is interrupted.

Further, the present invention is not limited to the above embodiments. For example, various services other than those exemplified so far can be considered as services to be provided.
