3 is a flowchart provided to explain a selective content download method using a multimedia message service according to an embodiment of the present invention.

Referring to FIG. 3, first, a multimedia message created by the calling mobile terminal 2 is transmitted to the MMSC 20 (S305).

The MMSC 20 extracts the content included in the multimedia message transmitted from the calling mobile communication terminal 2 and checks information such as a file name and content type of each content from the extracted content (S310).

The MMSC 20 transmits the extracted content and information such as a file name and content type for each content to the MMS content server 30 (S315). The MMS content server separates and stores the contents received from the MMSC 20 according to the content type and the file name, and transmits the location information where the respective contents are stored to the MMSC 20.

The MMSC 20 generates a notification message including information on the extracted content type, file name, storage location, and the like, and transmits the notification message to the receiving-side mobile communication terminal 200 (S325). At this time, the notification message transmitted from the MMSC 20 to the receiving-side mobile communication terminal 200 is converted into a short message form by the SMSC 40 and transmitted.

The receiving mobile terminal 200 receives a notification message in the form of a short message through the wireless transceiver 210. The data processor 220 decodes the notification message, extracts content information included in the notification message, and provides the extracted content information to the controller 270 (S330).

The controller 270 controls the display unit 250 to display content information (S335). In this case, the content information displayed on the display 250 includes information on the file name of the content and the type of the content so that the user can select the desired content.

The user of the receiving-side mobile communication terminal 200 checks the content file name and the type of the content displayed on the display unit 250, and selects at least one specific content required by the user using the input unit 260, thereby providing the content. Request the download (S340).

When there is a request for downloading a specific content from the user through the input unit 260 (S340: Y), the controller 270 checks the location information of the corresponding content, controls the wireless transceiver 210 to control the MMS content server 30 Request transmission of the corresponding content (S345).

At this time, the location information of the content, the content name of the content, information about the content type is transmitted to the MMS content server 30 together.

The MMS content server 30 receiving the request for transmission of specific content from the receiving mobile communication terminal 200 searches for the content requested for transmission and transmits the retrieved content to the receiving mobile communication terminal 200 (S350).

The control unit 270 of the receiving mobile terminal 200 stores the content received from the MMS content server 30 in the memory unit 240 and controls the corresponding content to be displayed on the display unit 250.

In this manner, the user of the receiving-side mobile communication terminal 200 can selectively download the desired content among the contents included in the multimedia message to be received.

In the above-described embodiment, the content information is implemented to be included in the notification message, but a separate message including only the content information in addition to the notification message may be implemented to be transmitted from the MMSC 20 to the receiving side mobile communication terminal 200. have.

In the above description of the preferred embodiment of the present invention, the present invention is not limited to the above-described specific embodiment, it is common in the art to which the invention belongs without departing from the spirit of the invention claimed in the claims. Various modifications can be made by those skilled in the art, and such changes are within the scope of the claims.

As described above, according to an embodiment of the present invention, it is possible to check the content information included in the multimedia message by using the notification message that the multimedia message has arrived, and accordingly, there is an advantage of receiving specific contents individually. have.

That is, since the contents included in the message can be checked individually without receiving the entire multimedia message, only the necessary contents can be individually received, thereby reducing the time and cost of downloading the content from the user of the multimedia message receiving side.
