Abstract

PURPOSE: A method for receiving a mail in a wireless terminal is provided to receive mails which are not read in each server using an IMAP4(Internet Mail Access Protocol Version 4) protocol when a mail server requests to receive new mail after inputting at least one mail server. CONSTITUTION: A user interface arranges mail servers according to order and selects one server to receive a mail according to a key signal(S200-S210). An E-mail client access a designated mail server(S230) and receives the mail(S250). In the case that a server to be connected does not exist, the stored mail is output on a display unit(S220,S260). A mail confirmation key signal is transmitted to the server in order to check the mail. A user inputs an identification of the mail server and user identifications through the user interface before inputting the mail receiving request key signal. The user interface receives and stores the mail server identification and user identifications(S200).

Description

Receiving mail on a wireless terminal {E-MAIL RECEPTION METHOD IN WIRELESS COMMUNICATION TERMINAL DEVICE}

The present invention relates to a method for receiving mail in a wireless terminal, and more particularly, to receive a mail from one or more servers, and to receive and process mail by only receiving new mail unread by a user at each server using the IMAP4 protocol. It relates to a receiving method.

In general, a method for receiving mail in a wireless terminal has been performed in such a manner that the wireless terminal receives mails from one server using the POP3 protocol.

Post Office Protocol Version 3 (POP3) uses only a few commands, such as specifying the sender, addressing, and sending the mail body.It is a communication protocol that uses a POP3 mail server to extract mail to personal computers around you. Except for the command for authentication, only 4 to 5 commands such as mail list, printout, and delete are used. Although it has the drawback of simplicity, it is widely used because of its universal use, but there are limitations due to changes in the Internet usage environment.

When the user inputs the name of the email server providing the POP3 protocol, his or her ID, and a password (S100), and receives a mail request (S110), the email client accesses the mail server (S120).

Then, the mail server detects a mail corresponding to the user information and transmits the detected mail to an email client (S130).

The email client stores the received mails (S140), and the user interface is displayed in alignment with the wireless terminal LCD (S150).

At this time, since the user was not provided with a protocol for distinguishing the mail read by the user, the developer had to devise an arbitrary method to implement this function.

This approach can be divided into two categories. The first is to delete the mail from the server after downloading it from the email server so that only new mail is left on the server. However, this solution has the disadvantage that the user cannot see the mail twice.

The second method is to distinguish the new mail by comparing the information of the downloaded mail with the information of the mail stored in the terminal. This method does not need to delete the mail in the server, but has the disadvantage of comparing all the mail, it is possible to compare the information currently stored in the terminal, there is a possibility that you can receive the email already deleted from the terminal again.

Both of these methods have to be processed by the POP3 mail client in the terminal, which causes a delay in receiving and processing multiple mails.

In addition, by implementing the number of servers that provide mail functions as one, there has been a problem in recent years that does not meet the requirements of users using multiple email servers.

Therefore, the present invention was created in order to solve the above-mentioned conventional problems, and after inputting one or more mail servers and requesting mail reception only once for each mail server, the user is not read by each server using the IMAP4 protocol. It is an object of the present invention to provide a mail receiving method in a wireless terminal for receiving mail only.

According to an aspect of the present invention, there is provided a method comprising: a first step of receiving one or more mail server identification information and user identification information registered in each server according to a mail reception request key signal input; A second step of accessing a mail server in the input order and receiving and storing mail detected by the server; Determining whether there is a server to be connected after performing the second step, and if there is a server to be connected to, returning to the second step; and outputting the stored mail to a display unit when there is no more server to be connected to; And a fourth step of transmitting the mail confirmation key signal to the server so that the server can check whether the mail is confirmed.

Hereinafter, an embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

2 is a system configuration for implementing a mail receiving method in a wireless terminal according to the present invention.

Referring to FIG. 2, the wireless terminal 10 is connected to one or more mail servers 40 through wired / wireless communication networks 20 and 30.

The application program of the wireless terminal 10 includes a user interface for inputting a user's desired mail server name and ID and password for the server, a mail receiving client implemented with IMAP4, and mail received by the client. Includes a mail management user interface for displaying.

The Internet Mail Access Protocol Version 4 (IMAP4) is a next-generation mail communication protocol for Internet mail provided by Netz Cape Communications Inc. and Microsoft Corp. in 1997 in a world wide web browser and set. The basic role is the same as that of POP3.

However, IMAP4 has been evaluated as the next generation mail access protocol for more reasons than POP3. IMAP4 is a way to access mail or bulletin board messages delivered and stored in private and public mailboxes on a mail server (MTA).

In other words, an e-mail client is a way to treat messages on a remote server as if it were a mail on its own computer.

For example, a user can manage the same mail at home, in the office, or while traveling on a laptop computer, without having to copy their mail on the IMAP4 server from the server to the client. In addition, it provides a feature called Disconnected operation, which allows you to synchronize your offline mail with mail on your mail server. This function is the same as Windows 95's 'My Filing' feature.

When a user accesses a mail server's mail from his home computer to POP3, POP3 transfers the mail to the home computer's hard disk and usually deletes the contents of the mail server. Therefore, in order to browse mail in his office the next day, there are problems that need to copy the mail stored in the computer at home.

However, since IMAP4 basically manages mail on the server, it can receive and manage the same mail anytime and anywhere. Unlike POP3, IMAP4 also allows you to create and manage your own personal folders on the server, so you can do mail sorting tasks like "Sent Items, Deleted Items, Archives, and Inbox." In addition, the shared folder function that can be used jointly with other users is provided so that the bulletin board function can be used through an e-mail client.

IMAP4 also provides optimal performance for users on slow networks. This is usually the case with a laptop connecting to your mail server via a modem. In the case of POP3, when several tens of megabytes of mail arrive at the user's mail server, the user has to see all the mails sequentially to see the subject.

However, IMAP4 has the ability to import only the message headers separately or only certain MIME content from MIME-style mail. Thus, users connected to low-speed networks can selectively view mail through the subject, without having to bring all of the text into their notebooks.

These advantages of IMAP4 have begun to be of commercial value by many vendors who have already paid attention to Internet mail, and many mail servers recently released support IMAP4.

3 is a signal flowchart illustrating a method of receiving an email in a wireless terminal according to the present invention.

Referring to FIG. 3, the method for receiving an email in a wireless terminal according to the present invention includes receiving one or more mail server identification information and user identification information registered in each server according to a mail reception request key signal input (S200 to S210). )Wow; Accessing the mail server in the input order, and receiving and storing the mail detected by the server (S230 to S250); After performing the step S250, it is determined whether there is a server to be connected, and if there is a server to be connected, it is returned to the step S230, and if there are no more servers to be connected, outputting the stored mail to the display unit (S220, S260) and ; And transmitting the mail confirmation key signal to the server so that the server can check whether the mail is confirmed.

Before the user inputs the mail reception request key signal, the user must input identification information of the mail server in which the user is registered and user identification information registered in each mail server through the user interface, and the user interface receives the inputs in order. Sort and store (S200).

One or more mail servers may be inputted, and an ID and password corresponding to each server should be input.

The user interface receives a 'receive mail only once' function selection signal for each mail server, and transmits the selection signal to a corresponding server through an email client so that the corresponding server is preset.

According to the mail reception request key signal input from the user, the user interface lists the mail servers stored in the setting step in order, and receives a server to receive the current mail from among the mail servers (S210).

The email client attempts to connect to the server specified by the user (S230).

An operation of the e-mail server according to the access of the e-mail client will be described in detail with reference to FIG. 4.

In response to the transmission of the mail reception request information from the wireless terminal, the mail server checks the user ID and password included in the mail reception request information and searches the mailbox according thereto (S241) to determine whether the user has a new mail. (S242).

As a result of the determination in S242, if there is a new mail, the newly arrived mail is detected and transmitted to the wireless terminal (S243), and then the read mail is displayed (S244).

As a result of the determination in step S242, if there is no new mail and after performing step S244, the existing mail is searched (S245).

At this time, ten e-mails are searched in order.

It is determined whether an unread mail reading is requested from the user (S246). When an unread mail reading is requested, the unread mail is detected and transmitted to the terminal (S247). If no read is requested, the server's operation is terminated.

The e-mail client receives and stores the e-mail transmitted from the e-mail server, and then determines whether there is a server to access (S220).

As a result of the determination of S220, when there are no more servers to access, new mails received from each server are sorted by server type or in chronological order and displayed to the user.

However, as a result of the determination of S220, if there is a server to be connected, the flow returns to step S230.

The present invention is not limited to the embodiments described above, and various modifications and changes can be made by those skilled in the art, which are included in the spirit and scope of the present invention as defined in the appended claims.

As described above, according to the present invention, if a user inputs the names of one or more servers in advance, and selects the Receive Mail Only Once function, the user can receive mails from each server, and the user cannot read them from each server using the IMAP4 protocol. There is an effect that can prevent the delay of processing the mail by receiving only new mail.
