Abstract

PURPOSE:To obviate such waste as many mail boxes of various formats are provided by executing a communication through the medium of an only mail box such as an intermediate format mail box. CONSTITUTION:A terminal user 1-1 instructs to transmit a mail by using an application program 3-1. As a result, transmitting information becomes a format of a mail and is registered in a mail box 4-1, and a mail format converting means 8 is actuated. The converting means 8 converts the mail format to an intermediate format, while referring to a mail format definition 7 and registers it in an intermediate format mail box 9. At the time of this registrations the intermediate format mail is distributed to every receiver. In such a way, it is unnecessary to save the mail of the mail box 4-1 since it is registered in the intermediate format mail box 9.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention, qiJFi, is used to exchange mail between different mail systems in a combination computer system in which there are a plurality of e-mail systems that exchange mail via mailboxes. Regarding a mail exchange system that enables.

[Conventional technology]

Figure wX2 is a schematic configuration diagram showing an example of a conventional communication system between different mail systems.

In the figure, terminal user 1-2 is using mail system 2-
Assume that the terminal user 1-1 attempts to receive a mail sent by the terminal user 1-1 using the application program 3-2.

First, applica n program 3-! Fi.

In order to retrieve mail sent by a mail system other than the own mail system 2-2, the mail format conversion means 8 is activated.

These converting means 8 companies request the application cage 1 program 3-1 to send an RL message to the terminal user 1-2 in the mail system 2-1.

The corresponding mail is taken out from the mailbox 4-1.

Therefore, in order for the terminal user 1-2 to receive mail, the mail system 2-1 must be in operation. Conversely, if the mail system 2-121 cannot be started for some reason, the terminal user 1-2 will not be able to receive or receive mail, and the terminal user 1-2 will not be able to receive or receive mail from the terminal user 1-1. You need to know which email system you used to send the email.

6. Mailbox K of other mail system 2-3
If there is an e-mail from the user 1-2 who has not yet used jIIl, #i, it is necessary to search the mailbox 4-3 using the e-mail system 2-3.

[Problem to be solved by the invention]

In this way, in the conventional communication system between different mail systems, in systems where there is a large number of mail exchanges between different mail systems, it is necessary to have multiple mailboxes, and these mailboxes must be accessed frequently. Furthermore, there are problems in that the mail cannot be received or received unless the mail system that sent the mail to search the mailbox is in operation.

[Means to solve the problem]

A mail exchange system between different types of mail systems according to the present invention is a system for exchanging mail between different types of mail systems.

and a mail format conversion means for format conversion between the mail format of each mail system and the intermediate format.

an intermediate format mailbox that stores intermediate format mail converted by the mail format conversion means;

The main feature is a mail search means for searching mail stored in the intermediate format mailbox and sending the retrieved intermediate format mail to the mail format conversion means.

[Effect]

By providing a mail search method that searches intermediate format mailboxes, the mailbox of each mail system is no longer required when exchanging mail, and the mail search method works when receiving emails to retrieve the mail of the corresponding terminal user. There is no need for the other party's mail system to be running in order to search the intermediate format mailbox.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a schematic diagram of a communication system between different mail systems showing an embodiment of the present invention.

In this embodiment, a terminal user 1-1 who is trying to send and receive emails using a mail system 2-1, and a terminal user who is trying to send and receive emails using a mail system 2-2. 1-2, and a communication signal between different mail systems 5.

The mail system 2-1 has an application cage program 3-1 and a mailbox 4-1.

The mail system 2-2 is the application program 3.
-2 and a mailbox 4-2.

The communication signal formula 5 between different mail systems includes a mail format definition means 6 that defines the mail format existing in the mailbox of each mail system, and a mail format definition 7 defined by this definition means R6.

and a mail format conversion means 8 which converts the mail of each mail system into an intermediate format while referring to the mail format definition 7, or converts the intermediate format into each mail format.

an intermediate format mailbox 9 for storing intermediate format mail converted by the conversion means 8;
and a mail search means 10 for searching the intermediate format mailbox 9 for the mail of the terminal user when a mail reception request is made via the terminal.

In the system of this embodiment, end, ili: user 1-
Consider a case where user 1 sends an email to terminal user 1-2.

First, the electric floor user 1-IFi instructs to send an e-mail using the application cage program 3-1.

As a result, the program 3-1a registers the transmission information in an email format in the mailbox 4-1, and performs normal email transmission processing such as notifying the terminal user 1-1 of the result. The mail format conversion means 8 is activated.

This conversion means 8 converts the mail format into an intermediate format while referring to the mail format definition 7, and registers it in the intermediate format mailbox 9. At the time of registration, intermediate format mail is sorted by recipient.

In order to be registered in the intermediate format mailbox 9 in this way, the mail in the mailbox 4-1 does not need to be saved. Therefore, the mailbox 4-1 is temporarily stored in the work file or memory 111? ) Good guess.

Thereafter, the terminal user 1-2 selects the terminal user 1-2.
Start the above-mentioned app cage reward program 3-2 in order to receive the mail from 1, and this program 3-2#
'i, activate the mail format conversion means 8 to receive the mail in the intermediate format mailbox 9.'i.

This conversion means 8 first starts the mail sample means IO,
As a result, this verification means 10 retrieves the mail addressed to the terminal user 1-2 from the intermediate format mailbox 9.
Then, the mail format conversion means converts the retrieved intermediate format mail into the mail format of the mail system 2-2 by referring to the mail format definition 7, and converts the retrieved intermediate format mail into the mail format of the mail system 2-2.
Register. In this case as well, similar to the mailbox 4-1, work files or memory can be allocated to the desk 4-2.

Thereafter, the application program 3-2#i performs normal reception processing, that is, processing such as displaying the received mail on the terminal.

〔Effect of the invention〕

As described above, the present invention can eliminate the waste of the conventional method by providing a large number of mailboxes of various formats in order to communicate through a single mailbox, which is an intermediate format mailbox.

In addition, the e-mail sample means works when receiving e-mails, and in order to search the e-mails of the corresponding electric floor users from the intermediate format mailbo-mex, it is possible to determine which e-mail system the terminal user who sent the e-mails uses to check the e-mails. There is no need for the terminal user receiving the e-mail to be concerned with whether the e-mail has been sent or not, and there is no need for the recipient's e-mail system to be in an active state at the time of reception.

Therefore, in the communication system according to the present invention, there is no need for a large number of mail systems and mailboxes owned by the mail systems to always exist, and waste of resources can be avoided. This is particularly effective in systems where many emails are exchanged between different email systems.
