Abstract

PURPOSE:To transmit a mail irrespective of a work station used by a user of a receiving destination by up-loading a mail for which a user finishes reading to a server, and erasing it from in a work station used by its user. CONSTITUTION:Based on user work station management information T2, an electronic mail is transmitted to a user of a work station of a transmitting destination by the server S2 of a receiving side, and when the user of the transmitting destination is not subjected to log-in, the electronic mail is preserved temporarily in the server S2, and at the time of log-in of the user of the transmitting destination, the electronic mail addressed to its user is down-loaded to the work station subjected to log-in, and also, the electronic mail for which the user finishes reading is up-loaded to the server S2, and erased from in the work station used by the user. Accordingly, at the time of transmitting the electronic mail, the user can transmit the electronic mail irrespective of the work station used by the user of the transmitting destination.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of sending and receiving mail on a plurality of networks in which distributed processing is performed, and is particularly used by a recipient user when the user sends mail. The present invention relates to a method for sending and receiving an email that allows the user to send an email without being aware of which workstation is present, and that does not require the recipient user to log in to another workstation to view the email.

[0002]

2. Description of the Related Art As a conventional method for transmitting and receiving electronic mail, an example of a centralized system and an example of a distributed system using workstations will be described with reference to FIGS. 2 and 3, respectively. (A) Centralized method of sending and receiving e-mail

As shown in FIG. 2, a server S1 of a network in which a plurality of machines M1 are connected to one server S1 is connected to a network S1 of a plurality of machines M2 in one server S2. It is connected to the server S2. Note that X, Y, and Z are machine names.

Now, a case where a mail is sent from the user a to the user c will be described as an example. Here, the user a
Is the machine X, and the user c is using the machine Z. First, the user a logs in from the machine X to the server S1 to send a mail. Next, a mail is created on the server S1, a user name is designated, and this mail is sent to the server S2. Next, the user c uses the machine Z to read the mail received to him.
To log in to the server S2. Finally, the mail addressed to itself is read from the received file on the server S2. (B) Sending and receiving electronic mail in a distributed manner

As shown in FIG. 3, each of the plurality of workstations WS has a file for mail reception. The mail is managed for each workstation WS and is stored in each workstation WS.
In addition, X, Y, Z, and T are the workstation names.

Now, a case where the user a sends an electronic mail to the user c will be described as an example. The workstations used by the users a, b, and c are referred to as X, Y, and Z, respectively. First, the user a sends a mail by designating the destination workstation name and user name from the logged-in workstation WS. Next, if the user c is logged in at the workstation Z, he / she can see the received mail as it is.

Further, when the user c is logged in at the workstation T, the mail is received and stored at the workstation Z, so that the workstation T cannot see the mail. However,
The conventional mail sending / receiving method as described above has the following problems. (A) In case of centralized system

Since only mails are exchanged between servers, it is necessary to log in to the server every time a mail is sent. Also, the recipient cannot read the mail addressed to himself without logging in to the server. (B) In case of distributed system

Since individual workstations must be designated when sending mail, it is difficult to determine the destination machine when sending mail to users who do not always use the same workstation. Also, if the recipient is logged in to a workstation other than the workstation to which the email arrives, the recipient cannot read the email addressed to himself.

[0010]

As described above, in the conventional mail sending / receiving method, when the user sends the mail, the user must be aware of the workstation used by the recipient user. However, there was a problem that the destination user had to log in to another workstation to view the mail.

An object of the present invention is that when a user sends a mail, the recipient can send the mail without being aware of the workstation used by the recipient, and the recipient user can see the mail. It is to provide a method for sending and receiving mail without having to log in to another workstation.

[0012]

To achieve the above object, a server of a network in which a plurality of workstations are connected to one server is connected to a server of another network having the same configuration. On a network system that performs distributed processing on each network,
In the method of sending and receiving mail distributed to each network,

First, in the invention described in claim 1, the logged-in user name and its workstation name are managed on the server of each network in which the distributed processing is performed, and the user / workstation management information is stored. Based on this, the receiving server determines the destination workstation and sends the email to the user of that workstation. Also, when the destination user is not logged in, the email is temporarily saved on the server. Incidentally, when the destination user is logged in, the mail addressed to the user is downloaded to the logged-in workstation.

According to the second aspect of the invention, the logged-in user name and the workstation name thereof are managed on the server of each network where the distributed processing is performed, and the user / workstation management information is stored. Based on this, the receiving server determines the destination workstation and sends the email to the user of that workstation. Also, when the destination user is not logged in, the email is temporarily saved on the server. Then, when the destination user is logged in, the mail for that user is downloaded to the logged-in workstation,
Further, the mail that the user has finished reading is uploaded to the server and deleted from the workstation used by the user.

[0015]

Therefore, in the mail transmitting / receiving method of the present invention, the logged-in user name and its workstation name are managed on the server of each network in which distributed processing is performed, and the server on the receiving side transmits to the destination. By automatically determining the workstation of, the user can send the mail regardless of the workstation used by the recipient user when sending the mail.

When the destination user is not logged in, the mail is temporarily stored on the server, and when the user logs in, the mail addressed to the logged-in user is automatically downloaded, so that the receiving side Also, you don't have to log in to the server or a specific workstation again to see the email, and you can get instant email to any workstation while you're logged in.

Next, on such a network system,
A method of transmitting / receiving electronic mail distributed over the networks N1 and N2 will be described. It is assumed here that the user a of the network N1 is logged in to the workstation X and sends an electronic mail to the user c of the network N2. First, user a
An email is created on the workstation X, and the email is sent to the user c. At this time, transmission confirmation can be designated. Next, the created electronic mail is sent to the server S2 of another network N2 via the server S1 of the network N1.

On the other hand, in the server S2, the workstation where the user c is logged in is searched for. At this time, the logged-in user workstation management information T2 is referred to.

As a result of this reference, it is found that the user c is not logged in, so this e-mail is stored on the server S2 as an unsent mail file.

Next, it is assumed that the user c now logs in to the workstation Z in such a state. Then,
At this time, all the e-mail addressed to the user c is downloaded to the workstation Z. Also, the user workstation management information is changed.

Then, the user c can display the electronic mail addressed to himself on the workstation Z. At this time, the response email is automatically sent to the sender when the full text is displayed for the email for which confirmation of transmission is specified.

Next, the unsent mail file on the server S2 is updated by the workstation Z. Then, this response e-mail is sent to the user a, which is the transmission source, in the same procedure as a general e-mail.

As described above, in the electronic mail transmission / reception method of this embodiment, the logged-in user name and the workstation name thereof are displayed on the servers S1 and S2 of the networks N1 and N2 in which the distributed processing is performed. Centralized management, the receiving server S2 automatically determines the destination workstation based on the user / workstation management information T2, and sends an e-mail to the user of the workstation, and When the user is not logged in, the e-mail is temporarily stored in the server S2, and when the destination user logs in, the e-mail addressed to the user is downloaded to the logged-in workstation. Upload the e-mail you have read to the server S2, and use the workstation used by the user. In which was to be erased from the ® in emissions. Therefore, when the user sends the e-mail, the user can send the e-mail regardless of the workstation used by the destination user.

Also on the receiving side, the e-mail is sent directly to the workstation where the destination user is logged in, and it is not necessary to log in to the server or a specific workstation to view the e-mail. Become.

In the above embodiment, the case of transmitting / receiving electronic mail has been described, but the present invention can be similarly applied to the case of transmitting / receiving other mail.

In the above embodiment, it is not essential for the present invention to upload the e-mail read by the user to the server and delete it from the workstation used by the user.

[0030]

As described above, according to the present invention, on the servers of each network in which distributed processing is performed,
It manages the logged-in user name and its workstation name, determines the destination workstation on the receiving server based on the user / workstation management information, and sends the email to the user of that workstation. Also, when the destination user is not logged in, the mail is temporarily stored in the server, and when the destination user is logged in, the mail addressed to that user is downloaded to the logged-in workstation. ,
In addition, if necessary, the user can upload the read mail to the server and delete it from the workstation being used by the user. A mail sending / receiving method can be provided in which a user can send a mail without being aware of the workstation used by the user, and the destination user does not need to log in to another workstation to view the mail.
