  Based on the input event signal from the portable terminal 20 to the server device 10, a transmission request for display drawing data G (or drawing data corresponding to the updated portion) corresponding to the data generated according to the application program of the server device 10. Is received (step C17 (YES)), the display drawing data G is received (step C18), written in the frame buffer RAM 25, and displayed on the display device 26 (step C19).

  As described above, when an input event signal corresponding to a user operation in the mobile terminal (client device) 20 is transmitted to the server device 10 (step C15 → C16), the server device 10 receives the received input event signal. Display drawing data G corresponding to the data generated according to the application program is generated and transmitted as a response to the portable terminal 20 (steps S20 → S21 → SB, S9 to S11), and is displayed on the display unit 26 of the portable terminal 20. Are displayed (steps C17 → C18, C19).

  In a normal operation state between the server and the client in such an SBC system, when mail data ML distributed by, for example, the Web mail server 30 is received in accordance with an application program owned by the mobile terminal (client device) 20 itself. (Step C4 (YES)), it is determined whether or not the received mail data ML is described in a data format according to the MIME format (Step C5).

  If it is determined that the received Web mail data ML is described in a data format (vMessage (.vmg)) according to the MIME format (step C5 (YES)), the server device 10 A data transfer request signal is transmitted to (step C6). When a response signal to the data transfer request signal is received from the server device 10 (step C8 (YES)), predetermined protocol data is generated (step C9), and the MIME format Web mail data ML is It is transmitted to the server device 10 (step C10).

  When it is determined that the transmission processing of the Web mail data ML to the server device 10 has been completed (step C11 (YES)), the transmission-completed Web mail data ML received and stored in the mobile terminal 20 is deleted. And is not stored in the terminal 20 (step C12).

  If it is determined in step C5 that the received mail data ML is not described in a data format according to the MIME format (step C5 (NO)), the mail data ML is data in MIME format. (Step C7), a data transfer request signal to the server device 10 is transmitted (step C6).

  In the state where the data transfer process to the server device 10 in steps C10 and C11 (NO) is not completed, when a cancel instruction is input in response to a user operation (step C13 (YES)), Data in the middle of the transfer process is discarded (step C12).

  On the other hand, when the server device 10 receives the data transfer request signal from the mobile terminal (client device) 20 (step S12 (YES)), the client NO. The web mail data ML in MIME format transferred from the portable terminal 20 is received for each vDD ID (No) corresponding to (step S13).

  If it is determined that the reception process of the Web mail data ML transferred from the portable terminal 20 has been completed (step S14 (YES)), the received Web mail data ML in the MIME format (see FIG. 4). A header is identified and extracted (step S15). Then, according to the information “BEGIN: VMSG” in the extracted header, the corresponding application related table (TBL) 13A (see FIG. 3) in the ROM 13 is referred to, and the received data (Web mail data ML) can be handled. An appropriate application program (mail processing program) is determined, and the corresponding application program (or the corresponding application server 10A) is activated and stored in the database DB (steps S16 and S17).

  At this time, the display drawing data G generated in accordance with the mail processing program activated in response to the transfer and reception of the Web mail data ML from the portable terminal 20 is subjected to the drawing update processing (step SB) in FIG. Then, it is transmitted to the portable terminal (client device) 20 (steps S9 to S11) and displayed on the display device 26 of the portable terminal 20 (steps C17 to C19).

  In addition, when the input event signal of cancellation according to user operation is received in the state which the data reception process from the portable terminal (client apparatus) 20 in said step S13, S14 (NO) is not complete | finished (step) S18 (YES)), the data in the middle of the reception process is discarded (step S19).

  Further, the portable terminal (client device) 20 is instructed to save schedule data (see FIG. 6A) generated by, for example, a schedule processing program according to a user operation in accordance with an application program of the portable terminal 20 itself. When the address book data (see FIG. 5) is received from the external portable terminal 40 by infrared communication or the like, as in the case of the Web mail data ML, any of the data is MIME format data. And then deleted from the portable terminal 20 (steps C4 to C12).

  The server device 10 receives the MIME-format schedule data (see FIG. 6A) transferred from the mobile terminal 20 or the address book data (see FIG. 5). In addition, the header of each received data is identified and extracted, and the corresponding application related table (TBL) 13A according to the information (“BEGIN: VCALENDER” and “BEGIN: VCARD”) in the extracted header. (Refer to FIG. 3), an application program (schedule processing program or address book management program) that can handle the received data (address book data or schedule data) is determined, and the corresponding application program (or the corresponding application Server 10C / 10B) is activated and stored in its database DB (step S1). 2-S17).

  At this time, the display drawing data G generated in accordance with the address book management program and schedule processing program activated in response to the transfer and reception of the address book data and schedule data from the portable terminal 20 is the drawing in FIG. It is transmitted to the mobile terminal (client device) 20 through the update process (step SB) (steps S9 to S11) and displayed on the display device 26 of the mobile terminal 20 (steps C17 to C19).

  FIG. 11 is a flowchart showing received data storage processing in each of the application servers 10A, 10B,... Provided in the server device 10 of the SBC system.
