  Before explaining the operation according to FIG. 2, in each device using the Bluetooth technology used in the mobile phone 40 and the terminal device 50, an operation called pairing for specifying the connection partner is performed only for the first time. First, this will be described.

  Specifically, the mobile phone 40 is brought into a searchable state. Subsequently, a search operation is performed from the terminal 50. A list of surrounding Bluetooth devices in a searchable state is displayed on the monitor unit 55 of the terminal 50, and the mobile phone 40 is designated from the list. Thereafter, by registering the key ID of the mobile phone 40 in the terminal 50, the connection process is completed. As described above, when the key ID of the mobile phone 40 is registered in the terminal 50, the pairing ends. Since the devices that have been paired once are automatically connected from the next time, when the mobile phone 40 enters the communicable area of the terminal 50, the terminal 50 automatically performs wireless communication with the mobile phone 40. Enable. The pairing function is provided in advance in each of the mobile phone 40 and the terminal 50.

  An operation of downloading software and content data in a state where the mobile phone 40 and the terminal 50 can communicate with each other as described above will be described.

  First, when the user carries the mobile phone 40 and approaches the vehicle, a process for searching for a connection partner by Bluetooth communication is performed (step 210). Further, in the terminal device 50, it is determined whether or not the mobile phone 40 has entered the communicable area (step 310). If it is determined that the mobile phone 40 has not entered the communicable area of the terminal 50, it is determined whether or not there has been a connection response of the mobile phone 40.

  When the mobile phone 40 accesses the terminal device 50, the terminal device 50 determines whether the mobile phone 40 is a communicable device based on a key ID (m1 $ 3) for identifying the mobile phone 40. The When the communication between the mobile phone 40 and the terminal device 50 becomes possible by checking the key ID in this way, the connection completion processing is performed in the mobile phone 40 and the terminal device 50 (steps 320 and 220). Communication between the mobile phone 40 and the terminal device 50 becomes possible.

  As a result, by accessing the external server 10 via the mobile phone 40 (and the base station 30 and the Internet 20) at the terminal 50, an e-commerce net shop site provided by the external server 10 can be viewed using a browser or the like. It can be browsed (step 230).

  Further, the external server 10 determines whether or not there is an access from the mobile phone 40. If there is no access from the mobile phone 40, it is determined whether or not there has been an access. On the other hand, when the terminal 50 accesses the e-commerce site via the mobile phone 40, the external server 10 determines that there is an access from the mobile phone 40 (step 110).

  In this state, the terminal 50 makes a purchase request for software and contents to the net shop (step 330). At this time, a purchase request to which a key ID (c2 %% 2) for identifying the terminal 50 is assigned is transmitted to the mobile phone 40. Upon receiving this, the mobile phone 40 transmits a purchase request including the key ID (m1 $ 3) for identifying the mobile phone 40 to the external server 10 (step 240).

  When the terminal 50 performs the purchase request transmission process for the mobile phone 40, the purchase program 300 shown in FIG. Further, even if the purchase program for the terminal 50 is terminated in this way, the terminal 50 may continue to function as a navigation device.

  When the mobile phone 40 that has been subjected to the purchase request transmission process in this manner is taken out of the vehicle by the user, the communication with the terminal 50 is disconnected. Then, the mobile phone 40 performs standby processing (step 250), and determines whether or not there is an access from the external server 10 (step 260). That is, if there is no access from the external server 10 to the mobile phone 40, the mobile phone 40 repeatedly executes the standby process.

  On the other hand, when a request for purchase of software or content is received from the terminal 50 via the mobile phone 40 as described above, the purchase request is accepted by the external server 10 operating the net shop (step 120). Then, processing for transmitting software and content data requested for purchase, creation processing such as a payment procedure, and the like are performed (step 130), and data delivery processing is performed (step 140). Specifically, in this delivery process, data including a key ID (m1 $ 3) for identifying the mobile phone 40 is transmitted from the external server 10 to the mobile phone 40.

  When the transmission process for data delivery ends, the sales program 100 returns to the start and waits for access to the external server 10 from the outside.

  When data is transmitted from the external server 10 as described above, the fact is received by the mobile phone 40 as described above. Thereby, in the mobile phone 40, it is determined that there is an access from the external server 10 (step 260). Then, the data transmitted from the external server 10 is received by the mobile phone 40, and the received data is stored (temporarily stored) in the memory unit 43 (step 270). At this time, the mobile phone 40 is away from the vehicle and cannot communicate with the terminal 50.

  On the other hand, in the terminal 50, after the purchase program is completed, the download program is executed. That is, the terminal 50 determines whether or not the mobile phone 40 has entered the communicable area (step 410).

  Further, when the user carries the mobile phone 40 having the data stored in the memory unit 43 and approaches the vehicle, a process of searching for a connection partner by Bluetooth communication is performed as described above (step 280). Accordingly, when it is determined that the terminal 50 has accessed from the mobile phone 40 (step 410), the mobile phone 40 communicates with the key ID (m1 $ 3) for identifying the mobile phone 40 in the terminal 50. It is determined whether the device is possible. By confirming the key ID in this way, connection completion processing is performed in the mobile phone 40 and the terminal device 50 (steps 420 and 290), and communication between the mobile phone 40 and the terminal device 50 is reconstructed and Bluetooth is performed. Communication by becomes possible.

  Thereafter, a download process is performed in which the data temporarily stored in the memory unit 43 of the mobile phone 40 is downloaded from the external server 10 to the terminal 50 (steps 295 and 430). When data is transmitted from the mobile phone 40 to the terminal 50 in this way, the data includes a key ID (c2 %% 2) for identifying the terminal 50, and the terminal 50 for which a purchase request has been made. Is verified and the data is downloaded. That is, even if a mobile phone with a different key ID enables communication with the terminal 50, the data stored in the mobile phone is not downloaded to the terminal 50.

  As described above, when the data temporarily stored in the mobile phone 40 is downloaded to the terminal device 50, the temporary storage program 200 in the mobile phone 40 ends, and the download program 400 in the terminal device 50 ends.

  As described above, in the present embodiment, the external server 10 is accessed from the terminal 50 via the mobile phone 40, and the data transmitted from the external server 10 is downloaded and stored in the mobile phone 40. It is characterized by. This eliminates the need for the mobile phone 40 to be connected to the terminal 50 until downloading of large-capacity software, audio data, data that takes time to create and modify map information, etc. is completed. Even if the owner of the mobile phone 40 carries the mobile phone 40 and leaves the vehicle, the purchased data can be continuously downloaded. That is, even if the connection state between the terminal 50 and the mobile phone 40 is not maintained, the data can be downloaded regardless of the data capacity and the download time.

  As described above, the terminal 50 is always connected to the network by providing a mechanism in which the mobile phone 40 can be used as a temporary storage (storage device) in a mobile phone network, a wireless LAN (Bluetooth) network, or the like. Even if you don't need to use the mobile phone 40 as a temporary storage, you can purchase and download custom data that takes time to create, data that you want to issue a license to the terminal 50, and normal data, It can be downloaded to the mobile phone 40 at any time.

(Other embodiments)
In the above embodiment, data is downloaded to the memory unit 43 of the mobile phone 40, but the data may be stored in an external memory that can be used by the mobile phone 40. In such a case, by storing the key ID together with the data in the external memory, it is possible to determine by which terminal the data stored in the external memory is requested.

  In the above embodiment, wireless communication is performed between the mobile phone 40 and the terminal 50, but wired communication may also be used. That is, even if the user takes the mobile phone 40 out of the vehicle, the data purchased at the net shop is temporarily stored in the memory unit 43 of the mobile phone 40. Therefore, the mobile phone 40 is again connected to the terminal 50 by a wired connection. The data temporarily stored in the telephone 40 may be downloaded to the terminal 50.

  Further, by using the download system shown in the above embodiment, licensed data such as MP3 can be purchased and cannot be reproduced in the mobile phone 40, but the data is downloaded to the terminal 50 and reproduced.
