In step S301, the calling terminal 201 and the called terminal 211 perform service registration. The service registration may be made through an online customer center or the like, and a mobile communication terminal or a personal computer may be used. In the service registration, the directory server 215 includes e-mail information for a terminal user, including terminal information (eg, a telephone number) for the corresponding terminal, that is, the calling terminal 201 and the called terminal 211. Stored. When the service registration is made in this way, the calling terminal 201 transmits an arbitrary multimedia message to the called terminal 211. The multimedia message transmits any one or more of a photo, a video, and a sound, and the calling terminal 201 transmits the message according to the message transmission procedure.

The originating terminal 201 transmits the multimedia message to the MS relay server 203 based on the MMS transmission protocol, for example, the MM1 protocol. In step S303, the MS relay server 203 queries the directory server 215 for registration of the corresponding service. That is, the header of the multimedia message received from the calling terminal 201 is parsed to extract phone number information of the called terminal 211 from the directory server 215. In addition, the MMS relay server 203 searches the directory server 215 for e-mail information of the called terminal 211 matched with the phone number information of the called terminal 211 in step S305.

As a result of the search, if the service registration for the destination terminal 211 is not made, the system is operated according to the multimedia message transmission routine, if the service registration for the destination terminal 211 is made, as in step S307 The email address is patched from the directory server 215. In step S309, the MS relay server 203 converts the multimedia message into an e-mail message type, that is, 'MIME (Multipurpose Internet Mail Extensions)' or 'MIME 2' based on the e-mail information about the multimedia message and the called terminal 211. .

In step S311, the MS delay server 203 transmits the email message to the email server 205. Email messages are sent according to the Simple Mail Transfer Protocol (SMTP). Here, the personal computer 213 may access the e-mail server 205 through a user authentication procedure, and receive the multimedia message using the personal computer 213 according to the selection of the called party. Meanwhile, in step S313, the email server 205 notifies the mobile email server 207 of the arrival of the email. This is for notifying the destination of the email to the destination terminal 211 regardless of the email confirmation procedure of the personal computer 213, and the called party is based on the email arrival notification received by the destination terminal 211 or the personal computer ( 213) may receive the email.

On the other hand, the mobile email server 207 enters the step S315, the directory server 215 retrieves the terminal information (phone number) of the destination terminal 211 corresponding to the email message. In step S317, the directory server 215 provides terminal information of the called terminal 211 according to a search request of the mobile email server 207. Thereafter, the mobile email server 207 requests the callback message transmission to the short message server 209 through step S319. In step S321, the short message server 209 transmits a callback message to the called terminal 211. The callback message includes a URL value in a short message, and the URL value includes an email address of the calling terminal 201.

Therefore, the called terminal 211 receives the callback message in step S323, and the called party inputs a specific key (eg, SEND button) of the called terminal 211 to receive the multimedia message. In step S325, the called terminal 211 is connected to the mobile email server 207 while driving the WAP browser. In operation S327, the mobile email server 207 accesses the email server 205 using IMAP4 (Internet Message Access Protocol 4) according to a callback connection. IMAP4 is an email standard protocol for receiving mail, and POP 3 may be used.

The destination terminal 211 requests a corresponding email reception in step S329 after logging in to receive an email. In step S331, the e-mail server 205 transmits a subject, a text, and the like for the e-mail to the mobile e-mail server 207. In step S333, the mobile email server 207 performs WAP document conversion on the email subject and body. That is, by converting the email into a wireless markup language (WML), the mobile email server 207 provides the WML document to the called terminal 211. Therefore, as in step S335, the called terminal 211 receives the e-mail message using a WAP browser, and confirms the contents.

As described above, the multimedia message transmission system and method using e-mail according to the present invention, by receiving the multimedia message provided from the originating terminal by e-mail according to the choice of the called party, the user received in a situation abroad Since the multimedia message can be confirmed by e-mail, it is effective to increase the limit of receiving a message. In addition, the user can be provided with a notification that the multimedia message has arrived by e-mail through a short message, so that the message can be checked in real time on a mobile communication terminal or a personal computer.
