Process 520 is executed.

  FIG. 12 is a flowchart showing an example of a file acquisition process by automatic data file transmission control executed by the mobile terminal device with communication function of FIG. In the figure, the user first confirms whether or not to obtain a file (step 515). FIG. 13 is a diagram showing a screen display example at the time of user confirmation in the processing of FIG. 12, 800 is a window for allowing the user to confirm file retrieval, 801 is a file retrieval confirmation message, and 802 is a retrieval instruction button , 803 are order stop buttons.

  In step 515, when the user instructs to stop the ordering (when the ordering cancel button 803 is pressed), the process is interrupted. Further, when the user instructs to order (when the order instruction button 802 is pressed), the telephone number 212 included in the new arrival message 200 is read and dialed to this telephone number 212 using the mobile phone transmission / reception unit 107. By doing so, line connection with the host computer 110 is performed (step 511). A transmission request message 250 obtained by setting a “file acquisition” request command as the command 251 and a file ID 261 specifying the new file specified by the new arrival message 200 transmitted as the command parameter 252 is set in step 511. Then, the file is received from the host computer 110 according to the procedure of the XMODEM protocol (step 513). After the reception of the file is completed, the line connected in step 511 is disconnected (step 514).

  In this embodiment, confirmation by the user is performed prior to file acquisition. However, it is also possible to acquire a file without user confirmation. In this case, step 515 may be deleted and the file acquisition process 510 may be executed from step 511.

  In addition, it is also possible to automatically redial if the line connection process 511 in Step 511 fails to connect the line in the processing in the above embodiment. Possible cases where line connection is not possible are (1) busy and (2) absence. (1) When busy, after disconnecting the telephone line once, the time is monitored by the timer 109, and after a certain time has elapsed (for example, after 1 minute), the processing may be restarted from step 511. . (2) In the absence, the elapsed time from the start of step 511 is monitored by the timer 109. After a certain period of time has elapsed (for example, when 1 minute has elapsed), the telephone call is stopped. Further, the time may be monitored by the timer 109, and the processing may be restarted from step 511 after a certain time has elapsed (for example, after 1 minute). By providing the portable terminal device 100 with such a function, it is automatically redialed when a line cannot be connected.

  FIG. 14 is a flowchart showing an example of an e-mail obtaining process by automatic e-mail transmission control executed by the mobile terminal device with communication function of FIG. In the figure, the telephone number 212 included in the new arrival message 200 is first read out and dialed to this telephone number 212 using the cellular phone transmission / reception unit 107, thereby establishing a line connection with the host computer 110 (step). 521). Then, a transmission command obtained by setting an “e-mail request” request command as the command 251 and an e-mail ID 271 specifying the newly arrived e-mail designated by the new arrival message 200 transmitted as the command parameter 252. The request message 250 is transmitted to the host computer 110 via the line connected in step 521 (step 522), and the electronic mail is received from the host computer 110 according to the procedure of the XMODEM protocol (step 523). After the reception of the file is completed, the line connected in step 521 is disconnected (step 524). Note that, in the e-mail obtaining process 520 as well as the file obtaining process 510, it is possible to execute a redial process when a line cannot be connected.

  As described above, according to the contents of the new message transmitted from the host computer 110, the user of the mobile terminal device 100 can receive the received file or e-mail without knowing the telephone number for connecting to the host computer 110. It can be ordered automatically.

  As another example, it is determined whether or not there is room to store the file (or e-mail) in the mobile terminal device 100 before starting the process of obtaining the file (or e-mail) specified by the new arrival message 200. You can also check the file and stop fetching files if you can't afford it. Hereinafter, such an embodiment will be described.

  FIG. 15 is a diagram showing another example of a format of a new arrival message transmitted / received by the automatic data distribution system of the present invention. The configuration of the command parameter 202 of the new arrival message 200 shown in FIG. 4 is changed according to the present embodiment. It is a thing. That is, in FIG. 15B, when a “file acquisition” instruction command is set as the command 201, the command parameter 202 is a file ID in addition to the file ID 211 and the telephone number 212 shown in FIG. The size 213 (size of the file specified by the file ID 211) is additionally set. In addition, in FIG. 15C, when an “e-mail retrieval” instruction command is set as the command 201, the command parameter 202 is added to the e-mail ID 221 and the telephone number 222 shown in FIG. The e-mail size 223 (the size of the e-mail specified by the e-mail ID 221) is additionally set.

  FIG. 16 is a flowchart showing another example of the file fetching process by the data file automatic transmission control executed in the mobile terminal device with communication function of FIG. 2, and the processes in steps 511 to 515 are the same as those in FIG. The description is omitted. In FIG. 16, the user first confirms whether or not to obtain a file (step 515). In step 515, when the user instructs to stop obtaining, the process is interrupted. In addition, when the user gives an order, the storage unit 104 shown in FIG. 2 sets the unused storage area of the capacity reserved for file storage and the new message 200. The size relationship with the file size 213 is compared (step 516). If the capacity of the unused storage area is larger than the file size 213, the processes in steps 511 to 515 are executed to complete the file acquisition process 510a. If the capacity of the unused storage area is smaller than the file size 213, as shown in FIG. 17A, a message 811 to cancel the file acquisition is displayed on the screen to notify the user and the file acquisition. The process 510a is stopped (step 517).

  In the above embodiment, the file acquisition is stopped, but the file may be received according to the user's selection as long as the capacity of the unused storage area permits. In this case, a message 813 as shown in FIG. 17B is displayed on the screen at the time of notification to the user in step 517 in FIG. Then, when the user presses the cancel button 814, the file acquisition process 510a is unconditionally stopped, and when the user presses the continue button 815, the file acquisition process 510a is performed after receiving the file in step 513 until there is no unused storage area. To be interrupted. Of the received file, the portion that has exceeded the capacity of the unused storage area and could not be stored is discarded.

  FIG. 18 is a flowchart showing another example of the e-mail obtaining process by the automatic e-mail transmission control executed in the portable terminal device with communication function of FIG. 2, and the processes in steps 521 to 524 are the same as those in FIG. The description is omitted. 18, the size of the unused storage area of the capacity reserved for storing emails in the storage unit 104 shown in FIG. 2 and the size of the email size 223 set in the new arrival message 200. The relationships are compared (step 525). If the capacity of the unused storage area is larger than the e-mail size 223, the processes in steps 521 to 524 are executed to complete the e-mail obtaining process 520a. If the capacity of the unused storage area is smaller than the e-mail size 223, as shown in FIG. 19, a message 812 to cancel the e-mail acquisition is displayed on the screen to notify the user, and e-mail acquisition is performed. The process 520a is stopped (step 526). In addition, in the case of obtaining e-mails, as in the case of obtaining files, e-mails are received until there is no unused storage area, and the portion that has exceeded the capacity of the unused storage area and cannot be stored is discarded. May be.

  In the above-described embodiment, an e-mail is obtained by transmitting an “e-mail obtaining” request command to the host computer 110. However, by using the portable information terminal 100 as a terminal, reading of the e-mail is performed. It is also possible to do this.

  FIG. 20 is a flowchart illustrating an example of an e-mail reading procedure using a login process executed by the mobile terminal device with communication function of FIG. This procedure is an e-mail reading procedure 550 when reading e-mail on the Internet, and data transmission / reception with the host computer 110 is performed character by character via the mobile phone transmission / reception unit 107 in FIG.

  In FIG. 20, first, the telephone number 212 included in the new arrival message 200 received from the host computer 110 is read out and dialed to the telephone number 222 using the mobile phone transmission / reception unit 107, thereby Are connected (step 551). Next, the user ID and password are transmitted to the host computer 110, and login processing to the host computer 110 is performed (step 552). Then, a mail command (for example, character string “mail”) is transmitted to set the host computer 110 in the mail mode (step 553), and then a mail display command (for example, character string “p”) is transmitted to newly arrive. The received mail is read (step 554). At this time, the contents of the mail are received from the host computer 110 character by character. When the reading of the mail is completed, an end command (for example, a character string “q”) is transmitted to end the mail mode (step 555). Finally, the line established in step 551 is disconnected (step 556). In the host computer 110 in this embodiment, an Internet e-mail program is operated instead of the host main process 600 (Internet e-mail programs are commercially available).

  As described above, when operating the mobile terminal device 100 as a terminal, whether or not to save the content of the e-mail received from the host computer 110 and displayed on the display unit 102 in the storage unit 104 of the mobile terminal device 100 is arbitrary. Can be set to In addition, as an e-mail reading procedure, an e-mail service or the like employed in individual personal computer communication can be used instead of the Internet. In this case, the character string may be transmitted according to a procedure individually defined in the personal computer communication.

  In all of the embodiments described so far, it is also possible to use a wired telephone instead of a mobile telephone. In this case, the mobile phone transmission / reception unit 107 in the mobile terminal device 100 may be replaced with a wired phone transmission / reception unit. Specific examples of the wired telephone transmission / reception unit include a data / FAX modem. Also, if the power is turned off until the message receiving unit 105 shown in FIG. 2 receives some message and the operation is started only after receiving the message, the power consumption by the portable terminal device can be suppressed. .
