Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wireless electronic mail system improved so that the update history of schedule data can be easily obtained.

[0002]

2. Description of the Related Art Conventionally, various so-called electronic notebooks (or electronic system notebooks) having a schedule, a telephone directory, a clock, various calculation functions, etc. have been developed, and are convenient to carry and used in various fields of business. Has been done.

Further, in recent years, mobile communication technology for realizing communication between a mobile body and an office or between mobile bodies has been remarkably advanced, and an electronic notebook is wirelessly communicated by using a teleterminal system. A wireless electronic mail system as a terminal has been developed. With such a system, for example, a mail document, a bulletin board document, or the like can be referenced from the electronic notebook terminal. Here, the bulletin board document is a document that is edited and posted so that a plurality of users can refer to it.

[0004]

However, in the conventional wireless electronic mail system, when referring to the schedule edited by the host computer side terminal from the electronic notebook terminal side, the update history of the schedule data is directly confirmed. It was not possible to do so, and all the data had to be fetched to the electronic notebook terminal side, regardless of whether or not a change had occurred since the last time it was referenced. Therefore, for example, even if no changes have been made since the time of the previous reference, it is necessary to transfer large-scale schedule data from the host computer side to the electronic notebook terminal side and check whether there are any changes or updates. However, there was a waste of labor and cost for the confirmation work.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a wireless electronic mail system capable of easily obtaining an update history of schedule data on the electronic notebook side, improving work efficiency and reducing costs.

[0006]

In order to achieve the above object, the wireless electronic mail system of the present invention is a wireless electronic mail system for performing wireless data communication between a host computer and an electronic notebook terminal. Schedule editing means for editing data and storing it in a schedule data file, update history editing means for editing the update history and reflecting it in the bulletin board data file when editing by this schedule editing means, and the schedule data file And a download means for transferring the data of the bulletin board data file to the electronic notebook terminal side.

[0007]

According to the present invention, when it is desired to refer to the schedule from the electronic notebook terminal side, first, a request for fetching bulletin board data is made, and the bulletin board data transferred by the download means on the host computer side is referred in advance. Then, by fetching only the necessary schedule data and referencing it, the number of large-scale data transfers is reduced, and the labor and cost of the confirmation work are reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to an embodiment shown in the drawings. FIG. 2 is a diagram for explaining the basic configuration of the wireless electronic mail system according to the embodiment of the present invention.

In the figure, the wireless electronic mail system according to the present embodiment includes a host computer 11, a communication controller 12, a gateway 13, a packet switching network 14, a shared use center (CC) 15 and a wireless base station (TT) 16. And a tele-terminal system 17 and an electronic notebook terminal 21 that performs wireless communication with the wireless base station 16. Host computer 11 and gateway 13
Is connected to a private line via the communication control device 12, and the gateway 13 and the teleterminal system 1 are connected to each other.
The packet exchange service (DDX-P) provided by NTT (Nippon Telegraph and Telephone Corporation) is used for the connection with the shared use center 15 of 7. In addition, the wireless base station 16 of the teleterminal system 15 and the electronic notebook terminal 21
For the connection with the wireless terminal, wireless communication is performed using a procedure dedicated to the teleterminal.

FIG. 1 is a diagram for explaining the configuration of a wireless electronic mail system according to an embodiment of the present invention.

In the figure, the host computer 11
On the side, the schedule editing means 21 for editing the schedule data, the schedule data file 22 for storing the schedule data edited by the schedule editing means 21, and the update history of the schedule when the editing is completed by the schedule editing means 21. And a bulletin board data file 24 for storing bulletin board data including the revision history, and a download means 25 for transmitting schedule data and bulletin board data to the electronic notebook terminal 20 side. There is. Here, the bulletin board function is a function that is edited / posted so that it can be referenced from a plurality of electronic notebook terminals 20.

Next, an operation example of the wireless electronic mail system having the above configuration will be described. FIG. 3 is a flow chart for explaining the operation of the wireless electronic mail system according to the embodiment of the present invention.

In the figure, first, in the terminal on the host computer 11 side, the schedule editing means 21 edits the schedule data (ST1), and the edited schedule data is stored in the schedule data file 22. (ST2). At the end of the schedule editing work, the update history editing means 23 edits the update data, and the edited result is reflected and recorded in the bulletin board data file 24. next,
When the electronic notebook terminal 20 side requests the bulletin board data import from the host computer 11 side (ST
4) The download means 25 transfers the bulletin board data stored in the bulletin board data file 24 to the electronic notebook terminal 20 side (ST5). On the electronic notebook terminal 20 side, the transferred bulletin board data is referred to, and when the schedule data is necessary, a request for importing the schedule data is made (S
T6). Next, when there is a request for schedule data, the host computer 11 side downloads 2
5 transfers the schedule data (ST7),
The electronic notebook side terminal 20 fetches the schedule data (ST8).

According to the wireless electronic mail system having the above configuration, when the schedule is changed / updated in the host computer 11 side terminal, the schedule editing means 21 edits the data, and the data is stored in the schedule data file 22. At the end of the editing work, the update history editing means 23 edits the update history and stores the changes in the bulletin board data file 24.
Then, when the user wants to refer to the schedule from the electronic notebook terminal 21 side, first, a request for fetching bulletin board data is made, and the download means 2 on the host computer 11 side.
Refer to the bulletin board data transferred by 5 and then
Import and refer to the necessary schedule data. Therefore, it is possible to confirm in advance whether or not the schedule has been updated on the bulletin board data. If there is no update, there is no need to send a request for schedule data, and if there is an update, only the necessary schedule data is fetched. In addition, it is not necessary to take all the data into the electronic notebook terminal side 20, the number of large-scale data transfers can be reduced, and the labor and cost of the confirmation work can be reduced.

In the present invention, the schedule is edited by the terminal on the host computer side, and the change history is reflected in the bulletin board function. However, the user (including a plurality of cases) who wants to refer to the schedule changes electronically. It can be referenced from either the notebook terminal or the host terminal.

[0016]

As described in detail above, according to the present invention, when the user wants to refer to the schedule from the electronic notebook terminal side, first, a request for fetching bulletin board data is made and the downloading means on the host computer side is used. By referencing the bulletin board data that is transferred in advance, and then by capturing and referencing only the schedule data that is required when there is an update, the number of large-scale data transfers can be reduced,
This has the effect of reducing the labor and cost of confirmation work.
