2 is a finite state diagram illustrating an operation flow of a pop three session according to an embodiment of the present invention.

3 is a flowchart illustrating an e-mail receiving method of a mobile communication terminal according to an exemplary embodiment of the present invention.

The present invention relates to a method for receiving an e-mail of a mobile communication terminal, and more particularly, to a method for receiving an e-mail of a mobile communication terminal, which is capable of receiving a required portion of e-mail by dividing a body and an attachment file of a desired size when receiving an e-mail. It is about.

With the spread of high-speed communication networks, the area of communication services using the Internet is expanding day by day. The typical use of the Internet is an e-mail service, and the offline mail function is partially replaced by e-mail. In particular, electronic mail has gained popularity as a means for transmitting and receiving files in that not only the original mail but also various files can be attached to the mail and transmitted.

Mail User Agents (MUAs), which allow users to create, send, and receive mail in electronic mail, can be broadly divided into using a mail-only program and using webmail on a website.

For example, a general transmission process of an e-mail using a mail-only program is as follows.

1 is an exemplary view showing a conventional e-mail transmission and reception process.

As the mail user agent 11, the sender creates an e-mail using a mail-only program such as Outlook Express. The mail user agent 11 delivers the e-mail created by the user to the mail transport agent (MTA) 13. That is, the created e-mail is sent to the mail transfer agent 18 of the sender's mail transfer server using the SMTP protocol.

The mail transfer agent 18 forwards the email to the mail transfer agent 18 of the designated host by referring to the header of the email message received from the mail user agent 17, and receives the mail transfer agent ( 18) forwards the e-mail to another system or interprets the destination address and delivers it to the user.

 On the other hand, a POP or IMAP server sends the e-mail stored in the mailbox to the recipient's mail user agent 17. In the case of pop (Post Office Protocol), the mail is physically transmitted from the server to the recipient. In the case of the Internet Message-Access Protocol (IMAP), only the header of the mail is sent to the recipient.

When a user receives an e-mail using a mobile communication terminal, the user receives a list of e-mails from the set pop three server, searches for the e-mails, and selects a specific mail from the list to view the contents of the desired mail.

In this case, the mail user agent mounted on the mobile communication terminal receives all of the message header, the body, and the attached file which are the whole message of the selected e-mail from the pop three server. Even if the user is not interested in the attachment of the message, since the attachment is received in addition to the body of the message, the reception time is long and the storage space of the received attachment is required. In particular, when the attachment is large, a problem occurs that a lot of overload occurs when the entire message is received by the pop three server.

Accordingly, the present invention has been made in view of the above problems, and in order to avoid a lot of overloads that may occur when receiving an e-mail, an e-mail reception of a mobile communication terminal that allows a user to select and receive only a desired part of the reception The purpose is to provide a method.

The present invention for achieving the above object comprises the steps of providing a selective reception function for the received mail when receiving the electronic mail in the mobile communication terminal; Selecting a part of the mail according to the setting of the selective reception function and issuing a command corresponding to the pop three server; And transmitting a part of the mail in response to the selection reception command received from the mobile communication terminal at the pop three server.

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

2 is a finite state diagram illustrating an operation flow of a pop three session according to an exemplary embodiment of the present invention.

When the mobile communication terminal accesses the pop three server and receives an e-mail, the mobile communication terminal disconnects after passing through the authorization state 21, the processing state 22, and the update state 23 in the initial connection and server connection.

In the authorization state 21, the ID and password are received from the mobile communication terminal to allow e-mail reception, and in the processing state 22, the mobile communication terminal transmits the message and the attached file of the selected mail according to the command.

3 is a flowchart illustrating a method of receiving an e-mail of a mobile communication terminal according to an exemplary embodiment of the present invention. As shown in FIG. 3, a mobile communication terminal initializes a socket connection and receives notification of entering into an authorization state from a pop three server. Steps S31 and S32; Determining whether to enter a processing state of a pop three session by receiving and receiving a user ID and a password from the pop three server at the mobile communication terminal (S33 to S35); In step S36 to S38, when the mobile communication terminal is notified of the entry of the processing state, the list command is issued to the selected mailbox to download the sender, the subject, and the mail size of all the e-mails to obtain information on receiving the e-mails (S36 to S38). Wow; When the mobile communication terminal receives a specific e-mail, providing a selective reception function of selecting and receiving a partial e-mail of the user selected mail; When the user selects a part of the mail to be received by using the selective reception function, giving a corresponding command to the pop three server (S39); Transmitting a portion of mail in response to a command for a selective reception function received from the mobile communication terminal at a pop three server (S40); When the user terminates the socket connection in the mobile communication terminal, the pop three server is notified of the step of ending the pop three session (S41).

The mail user agent of the mobile communication terminal is notified of entering the authorization state from the pop three server by initializing the socket connection (S31 and S32). At this time, the pop three server requests a user ID and a password from the mobile communication terminal to determine whether to enter the processing state (S33 ~ S35).

When it is determined to enter the processing state, the mobile communication terminal issues various commands to the pop three server to obtain information on reception of an e-mail (S36 and S37).

When a user receives a specific e-mail from the configured pop three server, the user can distinguish the selected e-mail in the form of message header, message body, and attachment. To this end, the pop three session function provides a selective reception function so that the contents of the mail can be partially selected and received.

When the user selects an appropriate mailbox, the mail user agent of the mobile communication terminal issues a list command to the selected mailbox to download the sender, the subject, and the mail size of all the electronic mails (S38). The list of e-mails is listed on the display window.

The user can select a specific mail from the list to check the contents of the desired mail and download only the header of the e-mail by using the selective reception function, or search a part or all of a specific mail by selecting a body or an attachment. (S39, S40).

The command used for the selective reception function has a mail set having a mail number or range as a parameter, and a mail data item having the whole mail, a body, a body (header, mime, text) as arguments. The command of the selective receiving function designates a mail number or range as a mail set, and indicates a mail requested to be received, and designates a whole mail, a body, a body [header, mime, text] as a mail data item, and a part of the mail to be received. .

For example, when the mobile terminal issues a Select Receive command consisting of 3 as the mail number of the mail set and a body [text] as the mail data item, the Pop Three Server interprets the command to extract the text from the body of the third e-mail. By passing to the mobile terminal.

Thereafter, when the user terminates the mail receiving application program, the mail user agent of the mobile communication terminal issues an end command to the pop three server to terminate the socket for the pop three session (S41).

As described above in detail, the present invention provides a selective reception function of partially selecting and receiving the contents of an electronic mail, thereby enabling the mobile communication terminal to efficiently use the communication speed and storage space when the electronic mail is received. .
