Further, on this screen, a key 323 of “local list” and a key 324 of “list in server” for switching the reading source of the member data are prepared. When the number of members that can be displayed at once in the name list 321 is registered, the name list 321 can be scrolled up and down with the scroll bar 326 and displayed. In this system, each terminal 100 is connected to the server 2 via a public line 600 and a gateway 500. Therefore, unlike a system connected to a LAN, it is not economical to keep the line connected at all times, and it is desirable to shorten the line connection time as much as possible.

Since a portable terminal has various memories,
By storing a member list as a local list in this memory and accessing the local list in this memory preferentially, the cost required for communication can be reduced. The user designates a member who wants to know the contents of the schedule with reference to the list with a touch pen or the like. When members of the local list are displayed in the name list 321, when the “Delete” key 327 is pressed,

A screen 330a in FIG. 9 shows a state in which the schedule is specified. When the "details" key 335 is pressed, a screen 350 shown in FIG. 12 is displayed. This screen displays the detailed contents 352 of the schedule of the member 351 in the designated time zone. This schedule is a reserved schedule, and the name of the sender of the reservation 3
53 is also displayed. The contents of the schedule and the like can be changed by pressing an "update" key 354. In the case where a schedule exceeding the number of lines that can be displayed at one time is registered in the schedule 332, the scroll bar 3
At 37, the schedule 332 can be scrolled up and down and displayed.

When a plurality of members are designated on the screen 320 and the "execute" key 325 is pressed, a screen 340 shown in FIG. 10 is displayed. On this screen, the contents of the schedule are displayed in a matrix with the member list 341 on the horizontal axis and the time zone 342 on the vertical axis.

When a member whose schedule is not registered in the center is included among a plurality of designated members, a message 345 is displayed on the screen as shown in FIG. In the screen of FIG.
Pressing 3 switches to a screen 360 shown in FIG.

This screen 360 is a screen for newly inputting and registering a schedule. On the screen, a member name 361 for registering a schedule and an input pad 365 are prepared. The date and time for setting the schedule are specified using the cursor, and the destination and the contents 362 of the schedule are input using the input pad 365. When a schedule is input and an “execute” key 366 is pressed, the schedule contents are registered in the server. At the same time, this schedule is also input to a “schedule” file prepared as a standard menu in the mobile terminal. Screen 200
Shows a display screen of this "schedule".

By pressing the "reservation" key 334 on the weekly schedule screen 330 for selecting one person or the "reservation" key 344 on the multiple members schedule screen 340, a screen 370 shown in FIG. 14 is displayed. Screen 370 is a screen for designating a member to be reserved. On this screen, the name of the member displayed on the member list 371 is specified. When a member to be reserved is selected and an “execute” key 375 is pressed, the screen is switched to a screen 380 shown in FIG. This screen is a screen for setting a new reservation. The name 381 of the member to be reserved and the input pad 385 are displayed. A date, a time, and the like are set, and the contents of the schedule and the like are input using the input pad 385. By pressing the "execute" key 386, the contents of the reservation are transmitted to the host, and the reservation is completed.

Next, a description will be given of a characteristic processing procedure in the schedule management system of the present invention having the above configuration and function. FIG. 16 is a flowchart of a process of automatically switching the schedule management data reading source based on the line connection state.

In step S100, the terminal determines the connection state to the public line. If it is determined in step S110 that the host computer is not connected to the host via the public line, the process proceeds to step S120, and if the data has been received in step S121, the process proceeds to step S122. Reads the schedule data stored in the memory of the terminal, and displays it on the screen in step S140.

If the schedule data has not been received in step S121, the process for non-reception is performed in step S123. As the non-receiving process, for example, a message indicating that "specified data has not been received" is displayed, but a process of automatically connecting to the host and receiving data may be considered.

When the online state is established in step S110, the process proceeds to step S130, where data is requested from the host in step S130, the data is received from the host in step S131, and displayed on the screen in step S140. The user can read the schedule by the same operation without being aware of whether the terminal is connected to the host via a public line.

Next, FIGS. 17 and 18 show a process of receiving only necessary data from the gateway in conjunction with a user operation when online. FIG. 17 shows the terminal 100,
The state of data transmission / reception between the gateway 500 and the host (server) 2 is shown. That is, when the terminal 100 requests the host 2 for one week of data via the gateway 500, the host 2 transfers, for example, 200 data corresponding to one week to the gateway 500.
Although the gateway 500 notifies the terminal 100 that there is 200 data, the memory capacity of the terminal 100 may not be capable of receiving 200 data at a time.
Therefore, the data is temporarily stored in the memory in the gateway 500, and only the required amount of data requested from the terminal 100 is transferred. As described above, by dividing and transferring the data, the communication time per time is reduced from the terminal 100 side.

In FIG. 18, in step S200, the terminal requests the number of schedules from the host via the gateway, and receives the number of schedules in step S201. In step S202, set the number of receivable transfers,
In step S203, a request for data of the set number is requested, and in step S204, schedule data is received.
At 205, it is displayed on the screen.

When the user operates the terminal, step S2
At 10, the contents of the operation are determined. For example, in the case of a display range switching operation such as scrolling, step S211
To determine the receiving status of the schedule. Step S21
If you have already received the data scrolled in step 2,
In step S205, the schedule is displayed. If data has not been received, the number of data to be transferred is set in step S213, and the process returns to step S203. If the user's operation is an operation other than the display range switching operation, the corresponding process is executed in step S220, and step S206 is performed.
Return to Further, the data to be transferred may be member data in the server. In that case, the required number of member data is transferred according to the range of the member list displayed on the terminal. FIG. 19 shows a flow of a process for selectively displaying a member list registered in the mobile terminal by a user in advance and a member list received from the host, and displaying the member list registered in the terminal with priority. .

When a member list display request is detected in step S300, the member data stored in the memory in the terminal is read in step S301, and step S302 is performed.
To display on the screen. When the user operates the terminal in step S303, the operation content is checked in step S304. When the user requests display of a member list in the host, the terminal requests member data from the host in step S310, receives the member data in step S311 and displays the member list in step S325.

If the user's operation is a request to display a list of members in the terminal, the member data in the memory of the terminal is read in step S320, and the screen is displayed in step S325.
If the user operation is other than the member list display request, the corresponding process is executed in step S330, and the process ends. The member registered in the memory of the terminal can freely select a partner frequently accessed by the user and set it freely.

The terminal program in the above-described schedule management system using the communication line of the present invention includes:
In addition to the case where the terminal program 60 is provided by being stored in the ROM 13 in the mobile terminal 100, as shown in FIG.
The portable terminal 10 is stored in a storage medium such as
0 may be installed in the flash memory 12 by using the PCMCIA controller 44.
In addition, a floppy disk or CD-R as an external storage medium
The terminal program may be stored in the OM or the like, and may be installed on the flash memory 12 therefrom.

Further, as shown in FIG. 20, the terminal program 60 is stored in the large-capacity storage medium 5 of the host computer 2 on the network, and is installed in the flash memory 12 of the portable terminal 100 through the network. Is also possible. By providing the terminal program through the network, the program provider does not need to distribute a storage medium such as a memory card to each user. The program can be centrally managed on the large-capacity storage medium 5 of the host computer 2 on the network, and the provision and management of the upgraded program can be easily performed.

In addition, the user does not need to carry a storage medium for installing the program, and can install the required application program anytime and anywhere as long as the user can connect to the network. As described above, by enabling the application program to be installed from the outside, the portable terminal 1 can be installed.
00 can be used not only as a terminal of a schedule management system using a communication line but also as a specialized device capable of installing various application programs and processing various functions.

[0036]

As described above, the present invention enables a registered member's schedule management system used only on a LAN connecting a host and a client to be used from a portable information terminal connected via a public line. To provide an expanded system. The mobile device has a schedule management program as an extension function, switches screens,
Schedule management can be performed. In this system, in the online state, data is received from the host, and in the offline state, the data is automatically determined and read from the memory in the portable terminal in which the received data is stored. Then, the schedule data can be searched by the same operation in both the online and offline states. Also, in conjunction with a switching operation of a data range to be displayed on the screen (scrolling operation, page switching operation, etc.), only data necessary for screen display is received from the gateway. This is effective when there is a limit on the memory for storing received data that can be mounted on the portable terminal, and the communication time per operation can be shortened. Further, conventionally, a list of members is stored in the terminal in advance when it is received from the host every time, and unnecessary communication is omitted.
Here, the member list received from the server can also be displayed by the user's selection, but the member displayed first is the member list stored in the mobile terminal. In addition, storing in the member list in the terminal includes a function of allowing a user to select a frequently accessed party or the like and register it.
