<System>
FIG. 1 shows a system to which an in-vehicle device and a portable terminal according to the present embodiment are applied.

  The system includes an in-vehicle device 100 and a mobile terminal 200. The in-vehicle device 100 is mounted on a moving body such as a vehicle, for example. The in-vehicle device 100 and the mobile terminal 200 are wirelessly connected by a short-range wireless communication method. The short-range wireless communication system includes Bluetooth. Portable terminal 200 is wirelessly connected to base station 300. The mobile terminal 200 includes a mobile phone. Base station 300 is connected to mobile communication network 400.

  A hands-free profile is set between the in-vehicle device 100 and the portable terminal 200. The in-vehicle device 100 instructs the mobile terminal 200 to acquire information on a business operator to which the mobile terminal 200 belongs by using the hands-free profile function. The mobile terminal 200 accesses the mobile communication network 400 by wireless connection with the base station 300 according to the command from the in-vehicle device 100, and acquires information on a business operator to which the mobile terminal 200 belongs. In Bluetooth standard version 1.2, the hands-free profile function includes a function to obtain information about the operator. The portable terminal 200 wirelessly transmits to the in-vehicle device 100 the information on the operator acquired by accessing the mobile communication network 400 via Bluetooth.

  The in-vehicle device 100 sets a profile for connecting the in-vehicle device 100 to the mobile communication network 400 via the mobile terminal 200 using the information on the business operator notified by the mobile terminal 200.

  The communication method in Bluetooth between the in-vehicle device 100 and the mobile terminal 200 differs depending on the communication method in which the mobile terminal 200 accesses the mobile communication network 400. Communication systems include GSM (Global System for Mobile Communications), WDM (Wideband CDMA: Wideband Code Division Multiple Access), Code Division Multiple Access (CDMA), PDC (Personal Digital). Cellular) etc. are included. Therefore, the user needs to set information on the business operator in the in-vehicle device 100 in advance. Until now, since it was not possible to acquire the business operator information by the mobile terminal 200, the user has to input the business operator information into the in-vehicle device 100 by manual input. According to the present embodiment, since the in-vehicle device 100 can cause the mobile terminal 200 to acquire information on the business operator, the setting of the business operator information can be automated. For example, in Japan, a communication method is uniquely determined from information on a business operator. Therefore, by acquiring information about the operator and setting the information about the operator, it is possible to set parameters relating to the communication method in Bluetooth. Hereinafter, setting a profile for the in-vehicle device 100 to connect to the mobile communication network 400 via the mobile terminal 200 is referred to as dial-up networking profile setting.

  In the present embodiment, a case where Bluetooth is applied as an example of a communication method for short-range wireless communication performed between the in-vehicle device 100 and the mobile terminal 200 will be described. Any other communication method may be used as long as the communication method includes a function.

<In-vehicle device>

Then, when the slave side answers the response, the connection state is established. A network formed between the master and the slave is called a piconet. In this embodiment, the in-vehicle device 100 is a master and the mobile terminal 200 is a slave.

  The BT unit of the Bluetooth communication unit 104 of the in-vehicle device 100 performs processing for establishing intra-piconet synchronization with the mobile terminal 200, processing for encoding / decoding transmission / reception signals, and the like. At the time of transmission, the Bluetooth communication unit 104 and the mobile terminal 200 digitally modulate a carrier wave signal with transmission data, and spread the spectrum of the modulated carrier wave signal by frequency hopping that switches the frequency every predetermined time. After amplifying the transmission signal to a transmission output level equal to or lower than a specified value, the transmission signal is transmitted from the antenna to the in-vehicle device 100 or the portable terminal 200 of the communication partner. In addition, a radio signal arriving from a communication partner is received via an antenna, and the radio signal is subjected to spectrum despreading and then digitally demodulated.

  A unique ID is given to the BT module. When connecting, the communication partner is identified by the ID. Also, when connecting the BT module for the first time, it is necessary to enter a PIN key (password). Pairing is completed when the correct PIN key is entered. Just enter and both are connected.

  The mobile terminal 200 has, for example, a hands-free profile function and a dial-up networking profile function. The hands-free profile function is a profile for realizing hands-free calling in a vehicle or in a headset. The hands-free profile function has communication outgoing / incoming functions. The dial-up networking profile function is a profile for dial-up connection to the Internet via a mobile phone or PHS (Personal Handyphone System).

The user inputs an operation signal indicating an operation content corresponding to the button to the control unit 102 by pressing the corresponding button.

  The display unit 108 is connected to the control unit 102. When a display signal is input from the control unit 102, the display unit 108 performs screen display based on the display signal. For example, the display unit 108 may be configured by a touch panel. When the display unit 108 is configured by a touch panel, a process corresponding to the part is performed by pressing the part displayed on the touch panel.

  The RAM 110 is connected to the control unit 102. For example, the RAM 110 stores data transferred from the mobile terminal 200. The data transferred from the portable terminal 200 may include, for example, phone book data, outgoing call history data, incoming call history data, and the like. The ROM 112 is connected to the control unit 102. The ROM 112 stores data transferred from the mobile terminal 200, for example. When data is transferred from the portable terminal 200, the control unit 102 manages data storage processing for the RAM 110 and the ROM 112. Further, when the user makes a data display request by operating the operation unit 106, the control unit 102 causes the display unit 108 to display the data stored in the RAM 110 or the ROM 112.

  The audio processing unit 114 is connected to the control unit 102. The sound processing unit 114 processes sound input from the microphone 116 and sound output from the speaker 118. When the Bluetooth communication unit 104 and the mobile terminal 200 are connected by the hands-free profile function and a hands-free call is performed, the voice processing unit 114 processes the voice input by the microphone 116. The signal subjected to the audio processing by the audio processing unit 114 is transmitted from the Bluetooth communication unit 104 to the mobile terminal 200 under the control of the control unit 102. The signal is transmitted from the mobile terminal 200 to the mobile communication network 400. On the other hand, if the signal received by the mobile terminal 200 from the mobile communication network 400 is voice, the signal is received by the Bluetooth communication unit 104 and output from the speaker 118.

  Demodulation section 210 is connected to reception transmission section 208, demodulates the downlink signal (carrier wave) input by reception signal section 208, and outputs the demodulated carrier wave to control section 202. The demodulator 210 demodulates, for example, phase-modulated digital data and inputs the demodulated data to the controller 202.

  The control unit 202 is connected to the demodulation unit 210, and outputs audio data to the audio processing unit 212 when audio data is input from the demodulation unit 210. When communication data is input from the demodulation unit 210, the control unit 202 performs protocol processing on the communication data and performs predetermined application processing. For example, the control unit 202 performs control to display communication data on the display unit 220 as application software data corresponding to the communication data.

  When the operator information acquisition command is input from the Bluetooth communication unit 224, the operator information acquisition control unit 2022 transmits a packet including the operator information acquisition command via the modulation unit 206 and the transmission unit 204. The information of the business operator included in the response is acquired via the reception unit 208 and the demodulation unit 210. The business operator information acquisition control unit 2022 inputs the business operator information to the Bluetooth communication unit 224. The Bluetooth communication unit 224 wirelessly transmits information on the business operator to the in-vehicle device 100. The information on the business operator is received by the Bluetooth communication unit 104 of the in-vehicle device 100.

  The modulation unit 206 is connected to the control unit 202, modulates the voice code carrier wave input by the control unit 202, and inputs the modulated carrier to the transmission unit 204. For example, the modulation unit 206 phase-modulates the carrier of the speech code input by the control unit 202 and inputs it to the transmission unit 204. The transmission unit 204 is connected to the modulation unit 206 and wirelessly transmits the modulated wave input by the modulation unit 206.

  The operation unit 222 is connected to the control unit 202. The operation unit 222 outputs the operation content and application input by the operation to the control unit 202 according to the operation by the user. The control unit 202 processes data according to the operation content and application input by the operation unit 222, performs protocol processing if necessary, and then, for example, phase-modulates the carrier wave by the modulator 206, and then transmits the transmission unit. Sent from 204.

  The memory 218 is connected to the control unit 202. The memory 218 stores phone book data together with an operating system (OS) and application software.

  The Bluetooth communication unit 224 is connected to the control unit 202. The Bluetooth communication unit 224 is configured by a Bluetooth module. Similarly to the Bluetooth communication unit 104 of the in-vehicle device 100, the Bluetooth communication unit 224 includes an RF unit that establishes wireless communication as a physical layer and a BT unit that performs processing according to the specification of Bluetooth. As a connection method of the RF part, Bluetooth defines a synchronous connection and an asynchronous connection. The synchronous connection is a line connection type point-to-point link formed between the Bluetooth communication unit 224 of the mobile terminal 200 and the Bluetooth communication unit 104 of the in-vehicle device 100, and is mainly used for transferring voice data. Is done. Asynchronous connection is a link for packet-switching type connection formed between the Bluetooth communication unit 224 of the mobile terminal 200 and the Bluetooth communication unit 104 of the in-vehicle device 100, and is mainly used for data transfer.

  In Bluetooth, the call mode side that calls a connectable BT module with a Paging message is called a master, and the side connected in response to the Paging message (in standby mode) is called a slave. Then, when the slave side answers the response, the connection state is established. A network formed between the master and the slave is called a piconet. In this embodiment, the in-vehicle device 100 is a master and the mobile terminal 200 is a slave.

  The Bluetooth communication unit 224 of the portable terminal 200 executes processing for establishing intra-piconet synchronization, encoding / decoding processing of transmission / reception signals, and the like with the BT unit of the Bluetooth communication unit 104 of the in-vehicle device 100. The Bluetooth communication unit 104 and the Bluetooth communication unit 224 digitally modulate a carrier signal with transmission data at the time of transmission, and spread the spectrum of the modulated carrier signal by frequency hopping that switches the frequency every predetermined time. After amplifying the transmission signal to a transmission output level equal to or lower than a specified value, the transmission signal is transmitted from the antenna to the in-vehicle device 100 or the portable terminal 200 of the communication partner. In addition, a radio signal arriving from a communication partner is received via an antenna, and the radio signal is subjected to spectrum despreading and then digitally demodulated.

  A unique ID is given to the BT module. When connecting, the communication partner is identified by the ID. Also, when connecting the BT module for the first time, it is necessary to enter a PIN key (password). Pairing is completed when the correct PIN key is entered. Just enter and both are connected.

<Data communication setting method>
4 and 5 show a data communication setting method in the in-vehicle device 100 according to the present embodiment.

  The in-vehicle device 100 displays a main menu screen (step S402). The control unit 102 displays a main menu screen on the display unit 108.

  The in-vehicle device 100 determines whether or not the hands-free profile function in Bluetooth is not set (step S404). The hands-free profile setting unit 1022 determines whether the hands-free profile function is not set in the Bluetooth communication unit 104.

  When the hands-free profile function is not set (step S404: NO), the in-vehicle device 100 determines whether the portable terminal 200 used for data communication is not selected (step S406). When the hands-free profile setting unit 1022 determines that the hands-free profile function is not set, the mobile terminal setting unit 1026 determines whether the mobile terminal 200 used for data communication is not selected.

  In step S404, it may be determined whether the hands-free profile function of the in-vehicle device 100 is set, or it may be determined whether a device having the hands-free profile function is registered. By determining that the hands-free profile function in the in-vehicle device 100 is set, the processing load can be reduced. When the management of the mobile terminal 200 is a function unit, when the hands-free profile function is set by another device, for example, an audio device, the hands-free profile function of the mobile terminal 200 is set. Even if not, the hands-free profile function is set. However, by determining that each device having the hands-free profile function is registered, even if the hands-free profile function is set by another device, the hands-free profile function of the mobile terminal 200 is set. Therefore, the hands-free profile function of the mobile terminal 200 can be set reliably.

  When the hands-free profile function is not set (step S404: YES), the in-vehicle device 100 determines whether an operation for performing connection setting has been performed (step S408). For example, a screen for performing Bluetooth connection settings may be displayed on the main menu screen. For example, a display for navigating the setting such as “Various settings are required for connection to the in-vehicle network service. Do you want to set?” Is displayed. For example, when the hands-free profile function is not set, the hands-free profile setting unit 1022 displays on the display unit 108 to prompt the user to set the hands-free profile function. By performing display for prompting the setting of the hands-free profile function, the setting of the hands-free profile function can be navigated to the user.

  If the user performs an operation corresponding to “No” while the display for prompting the setting of the hands-free profile function is being performed (step S408: NO), the process returns to step S402, and the main menu screen is displayed. Is displayed. For example, when the display unit 108 is configured by a touch panel, the hands-free profile setting unit 1022 is pressed by pressing “No” among “Yes” and “No” displayed on the touch panel. It is determined that the function is not set, and the display unit 108 is controlled to display the main menu.

  On the other hand, if the user performs an operation corresponding to “Yes” while the display for prompting the setting of the hands-free profile function is being performed (step S408: YES), the Bluetooth setting screen is displayed. . For example, by pressing down “Yes” among “Yes” and “No” displayed on the touch panel, the hands-free profile setting unit 1022 determines to set the hands-free profile, and the display unit 108 Control to display the Bluetooth setting screen.

  While the Bluetooth setting screen is being displayed, the user can perform any one of “registration”, “change”, and “return”.

  The in-vehicle device 100 determines whether an operation for performing “registration” has been performed (step S410). When the user performs an operation corresponding to “registration” (step S410: YES), a Bluetooth connection screen is displayed, and connection setting is automatically performed (step S412). For example, when “registration” is pushed down among “registration”, “change”, and “return” displayed on the touch panel, the handsfree profile setting unit 1022 can perform handsfree with the mobile terminal 200. It is determined that the profile function is to be set, and the Bluetooth connection screen is displayed on the display unit 108, and the connection setting is automatically performed by setting the hands-free profile function with the mobile terminal 200.

  If the user performs an operation other than the operation corresponding to “registration”, for example, an operation corresponding to “change” while the Bluetooth connection setting screen is displayed (step S410: NO), the Bluetooth change is performed. A screen is displayed. On the Bluetooth change screen, the user can change the connection setting. For example, when “change” is pressed among “registration”, “change”, and “return” displayed on the touch panel, the hands-free profile setting unit 1022 determines that the setting change by Bluetooth is performed. The Bluetooth change screen is displayed on the display unit 108. The user can change the setting on the Bluetooth change screen.

  The in-vehicle device 100 determines whether an operation for changing the connection setting has been performed (step S414). For example, the hands-free profile setting unit 1022 determines whether an operation for changing connection settings has been performed. When it is determined that an operation for changing the connection setting has been performed (step S414: YES), the in-vehicle device 100 changes the connection setting (step S416). Then, the process returns to step S410. On the other hand, when it is not determined that the operation for changing the connection setting has been performed (step S414: NO), the process returns to step S408.

  Further, the Bluetooth setting screen may be displayed by performing an operation corresponding to “complete” of the setting change or an operation corresponding to “return”.

  While the connection setting with the portable terminal 200 is automatically performed in step S412, the in-vehicle device 100 determines that no connection abnormality has occurred (step S418). For example, the hands-free profile setting unit 1022 determines that no abnormality has occurred in connection with the mobile terminal 200. When the connection abnormality has occurred (step S418: YES), the in-vehicle device 100 displays an error (step S420). For example, when the hands-free profile setting unit 1022 determines that an abnormality has occurred in the connection with the mobile terminal 200, the hands-free profile setting unit 1022 controls the display unit 108 to display an error. For example, the display may be changed according to the error. Further, for example, it may be displayed that connection with the mobile terminal 200 has failed. The display may be automatically deleted. Then, the process proceeds to step S436 described later.

  On the other hand, when no connection abnormality has occurred in step S418 (step S418: NO), the in-vehicle device 100 may display a communication setting screen. On the communication setting screen, a display for notifying that the connection with the mobile terminal 200 has been completed may be performed. For example, when the hands-free profile setting unit 1022 determines that there is no abnormality in the connection with the mobile terminal 200, the hands-free profile setting unit 1022 may control the display unit 108 to display the communication setting screen. For example, you may make it display that it was able to connect with a portable terminal. The display may be automatically deleted.

  The in-vehicle device 100 instructs the mobile terminal 200 to acquire information on a business operator to which the mobile terminal 200 belongs (step S422). For example, the provider information acquisition command creation unit 1024 creates a provider information acquisition command that causes the mobile terminal 200 to acquire information on the provider to which the mobile terminal 200 belongs, and causes the Bluetooth communication unit 104 to transmit the provider information Enter a get command. The Bluetooth communication unit 104 wirelessly transmits the operator information acquisition command input by the operator information acquisition command generation unit 1024 to the mobile terminal 200. The business operator information acquisition command is received by the Bluetooth communication unit 224 of the mobile terminal 200. The Bluetooth communication unit 224 inputs the company information acquisition command to the company information acquisition control unit 2022. The carrier information acquisition control unit 2022 wirelessly transmits a packet including the carrier information acquisition command via the modulation unit 206 and the transmission unit 204 in accordance with the carrier information acquisition command input by the Bluetooth communication unit 224. The provider information included in the response is acquired via the reception unit 208 and the demodulation unit 210. The packet wirelessly transmitted by the transmission unit 204 is received by the base station 300. The base station 300 transmits the packet to a device having information on a carrier connected to the mobile communication network 400. When receiving the packet, the apparatus having the information on the business operator returns a response packet including information on the business operator to which the mobile terminal 200 belongs. The business operator information acquisition control unit 2022 inputs the business operator information to the Bluetooth communication unit 224. The Bluetooth communication unit 224 wirelessly transmits information on the business operator to the in-vehicle device 100. The information on the business operator is received by the Bluetooth communication unit 104 of the in-vehicle device 100. The Bluetooth communication unit 104 inputs the information of the operator to the dial-up networking profile setting unit 1028.

  The in-vehicle device 100 displays a communication setting screen when acquiring information on the business operator. The dial-up networking profile setting unit 1028 displays a communication setting screen on the display unit 108, and sets a dial-up networking profile using the information of the business operator (step S424). For example, the dial-up networking profile setting unit 1028 sets a dial-up networking profile function with the mobile terminal 200. On the communication setting screen, the user can perform an operation corresponding to “return”. Further, when the setting of the dial-up networking profile function is completed, an operation corresponding to “complete” can be performed. For example, a display indicating “completed” is displayed on the communication screen setting screen. The in-vehicle device 100 determines whether an operation corresponding to “completion” has been performed (step S426). When the user performs an operation corresponding to “completion” (step S426: YES), the in-vehicle device 100 determines whether the operator is not set (step S428). For example, the dial-up networking profile setting unit 1028 determines whether the operator has not been set.

  When the operator is not set (step S428: YES), the in-vehicle device 100 displays on the communication setting screen notifying that the operator is not set (step S430). Thereafter, the process returns to step S424. For example, the in-vehicle device 100 may perform a display notifying that the business operator is not set, erase the display, and then return to step S424. In step S424, the dial-up networking profile may be set based on the information on the business operator acquired in step S422. Even though the dial-up networking profile setting unit 1028 has set the dial-up networking profile, the fact that the operator information is not set is that the operator information cannot be acquired in step S422. It may be caused by failure to set information. If the operator information cannot be acquired in step S422, there is a high possibility of failure even if an attempt is made to set the dial-up networking profile again in step S424. Therefore, even if the dial-up networking profile is set, if the operator information is not set, the user may be prompted to set it manually.

  On the other hand, when the operator is not set (step S428: NO), the in-vehicle device 100 determines whether the mobile terminal 200 is set not to be used for data communication (step S432). For example, the dial-up networking profile setting unit 1028 determines whether the mobile terminal 200 is set as a terminal that is not used for data communication.

  When the portable terminal 200 is set as a terminal that is not used for data communication (step S432: YES), the in-vehicle device 100 confirms that it is set not to be used for communication (step S434). For example, the in-vehicle device 100 may display on the communication setting screen to confirm that data communication cannot be performed because the terminal is not used for data communication. For example, the dial-up networking profile setting unit 1028 displays on the communication setting screen displayed on the display unit 108 to confirm that data communication cannot be performed because the terminal is not used for data communication. .

  In step S434, since the terminal that is not used for data communication is set on the communication setting screen, the user confirms “Yes” or “No” on the screen on which confirmation that data communication cannot be performed is performed. Can be selected. When the operation corresponding to “No” is performed (step S434: NO), the process returns to step S424. In step S424, it is prompted to change the mobile terminal 200 to be used for data communication. Then, the dial-up networking profile is set to reflect that the mobile terminal 200 is changed to a terminal used for data communication.

  On the other hand, when the portable terminal 200 is not set as a terminal that is not used for data communication at step S432 (step S432: NO) and when an operation corresponding to “Yes” is performed at step S434 (step S434: YES), A transition is made to a state in which the dial-up networking profile function can be set and edited (step S436). For example, dial-up networking profiles can be manually set and edited. The dial-up networking profile unit 1028 sets and edits the dial-up networking profile in accordance with an operation by the user.

  When it is determined in step S406 that the mobile terminal used for data communication is not selected (step S406: YES), the in-vehicle device 100 determines whether an operation for selecting the mobile terminal has been performed (step S438). For example, the in-vehicle device 100 may display a screen for setting a mobile terminal permitted to be used for data communication on the main menu screen. For example, a display for navigating the setting such as “Various settings are required for connection to the in-vehicle network service. Do you want to set?” Is displayed. For example, when the mobile terminal 200 used for data communication is not set, the dial-up networking profile setting unit 1028 displays on the display unit 108 to prompt the user to set the mobile terminal 200 used for data communication.

  When the user performs an operation corresponding to “No” while the display for prompting the setting of the mobile terminal 200 used for data communication is performed in Step S438 (Step S438: NO), Step S402 is performed. The main menu screen is displayed. For example, when the display unit 108 is configured by a touch panel, the dial-up networking profile setting unit 1028 performs data communication by pressing down “No” among “Yes” and “No” displayed on the touch panel. It is determined that the mobile terminal 200 to be used is not set, and the display unit 108 is controlled to display the main menu. On the other hand, when the user performs an operation corresponding to “Yes” while the display for prompting the setting of the mobile terminal 200 used for data communication is performed in Step S438 (Step S438: YES), A portable terminal selection process is performed (step S440). For example, a mobile terminal selection screen may be displayed. For example, by pressing down “Yes” of “Yes” and “No” displayed on the touch panel, the dial-up networking profile setting unit 1028 determines to set the mobile terminal 200 used for data communication. The display unit 108 is controlled to display a portable terminal selection screen.

  While the mobile terminal selection screen is displayed in step S440, the user can select a mobile terminal to be used, in other words, a mobile terminal that is allowed to be used for data communication. The user can select “return” or “complete” while the mobile terminal selection screen is displayed. When an operation corresponding to “complete” is performed, the in-vehicle device 100 sets the mobile terminal selected in step S440 as a mobile terminal that can be used for data communication.

  The in-vehicle device 100 determines whether or not the mobile terminal used for data communication is set to enable data communication (step S442). For example, it is determined whether a dial-up networking profile is set.

  If it is determined in step S442 that the dial-up networking profile is set (step S442: YES), the process proceeds to step S432. On the other hand, when it is determined in step S442 that the dial-up networking profile is not set (step S442: NO), the process proceeds to step S422.

  When it is determined in step S406 that the mobile terminal 200 used for data communication is selected (step S406: NO), the in-vehicle device 100 determines whether the mobile terminal 200 is set to be usable for data communication. (Step S444). For example, the dial-up networking profile setting unit 1028 determines whether the mobile terminal 200 is set to be usable for data communication.

  When portable terminal 200 is not set to be usable for data communication in step S444 (step S444: NO), in-vehicle device 100 displays a screen for setting Bluetooth on the main menu screen. For example, a display for navigating the setting such as “Various settings are required for connection to the in-vehicle network service. Do you want to set?” Is displayed. For example, if the mobile terminal 200 is not set to be usable for data communication, the dial-up networking profile setting unit 1028 displays on the display unit 108 for prompting the setting to make the mobile terminal 200 available for data communication. .

  The in-vehicle device 100 determines whether or not the use of the mobile terminal has been set (step S446). When the user performs an operation corresponding to “No” while the display for prompting the setting to make the portable terminal 200 available for data communication is performed (step S446: NO), the process proceeds to step S402. Return to the main menu screen. For example, in the case where the display unit 108 is configured by a touch panel, the dial-up networking profile setting unit 1028 causes the mobile phone to be moved by pressing “No” out of “Yes” and “No” displayed on the touch panel. It is determined that the setting for enabling use is not performed, and the display unit 108 is controlled to display the main menu. On the other hand, when the user performs an operation corresponding to “Yes” while the display for prompting the setting to make the portable terminal 200 available for data communication is performed in Step S446 (Step S446: YES). ), And the process proceeds to step S422. For example, by pressing down “Yes” among “Yes” and “No” displayed on the touch panel, the in-vehicle device 100 acquires information on a business operator to which the mobile terminal 200 belongs from the mobile terminal 200. To order. Thereafter, the dial-up networking profile setting unit 1028 sets a dial-up networking profile.

  When the mobile terminal is set to be usable in step S444 (step S444: YES), the in-vehicle device 100 displays a browser screen (step S448).
