The present invention relates to a method of downloading a multimedia messaging service (MMS) message to a receiving terminal, and more particularly, in downloading a multimedia message stored in a database by a request of a receiving terminal to a receiving terminal. The present invention relates to a method of reconfiguring and transmitting a multimedia message most suitable for a specification of a receiving terminal when a multimedia message cannot be converted into a form suitable for a specification, and a recording medium recording a program for executing the same.

Multimedia Messaging Service (MMS) is a service defined in the international standard recommendation 3rd Generation Partnership Project (3GPP) Technical Specification (TS) 22.140 and 23.140. It is a service to transmit and receive multimedia data.

The MMS presented in the standard recommendation adopts a store and forward method as a message transmission method. A multimedia message is sent encapsulated with media content, information needed to describe the media content, and address information identifying the recipient of the message. The multimedia message is transmitted from the sender terminal to the multimedia messaging service center (MMSC), which notifies the receiver terminal of the receipt of the message. The multimedia message stored in the multimedia messaging service center is transmitted to the receiver terminal by the receiver request.

The second generation user terminal 11 is connected to the MMS relay 19 through the second generation mobile network 13, and the third generation user terminal 12 is connected to the MMS relay via the third generation mobile network 14. 19). The roaming MMS user terminal 15 is then connected to the MMS relay 19 via the mobile access network 16 and the Internet / IP network 18. The external server 23 and the wired email client 17 can also be connected to the MMS relay 19 via the Internet / IP network 18. The MMS relay 19 is connected to the MMS server 20 and the subscriber database (DB). The MMS server 20 is connected with a message storage unit 21 for storing the received multimedia message.

In such a network, a user composes a multimedia message to transmit the multimedia message to a specific receiver terminal. As described above, the multimedia message includes a text, a video or a still image, an audio, an audio, and the like. When the created multimedia message is transmitted from the calling terminal to the MMS server 20 through the MMS relay 19, the MMS server stores the received multimedia message in the message storage unit 21, and there is a received multimedia message to the receiving terminal. Send a message to notify you. Then, the receiving terminal accesses the MMS server using the message number included in the notification message and address information of the server where the multimedia message exists. Then, the receiving terminal is designated to download the stored multimedia message. When the reception of the message is completed, the receiving terminal releases the connection with the MMS server.

On the other hand, before the MMS server downloads the multimedia message to the receiving terminal, after checking the specifications of the receiving terminal, for example, the size of the memory of the receiving terminal, the size of the screen, the codec type, the CPU information of the terminal, program version information, The multimedia message stored in a form suitable for the identified specification of the receiving terminal is converted and transmitted to the receiving terminal.

Here, the still image of the multimedia message is a SIS type. The SIS type image can be converted in color depth, but not in size. In addition, MIDI audio data cannot be converted. Therefore, when the multimedia message includes such image information or audio information, when the specification of the receiving terminal cannot accommodate this, there is a problem that the original message is not reproduced or cannot be reproduced even when downloaded to the receiving terminal.

Therefore, in order to solve the problems of the prior art as described above, in the download of the multimedia message stored in the database by the request of the receiving terminal to the receiving terminal, it is impossible to convert the multimedia message into a form suitable for the specification of the receiving terminal. In this case, the present invention provides a method for downloading a multimedia message to a receiving terminal capable of providing a multimedia message service to all of the various receiving terminals by reconfiguring and transmitting the multimedia message most suitable for the specification of the receiving terminal, and a recording medium recording the same. There is this.

According to an aspect of the present invention, there is provided a method for downloading the stored multimedia message to the receiving terminal by a download request of a specific receiving terminal after storing the multimedia message transmitted from a specific transmitting terminal. A first step of confirming the specifications; A second step of checking an image type included in the multimedia message when the stored multimedia message cannot be converted to meet the specification of the receiving terminal; A third step of confirming whether an image file having the same content having a size corresponding to the image type identified in the second step is stored in the database; A fourth step of reading a corresponding image file from the database and replacing the image included in the multimedia message and transmitting the read image file to the receiving terminal, if it exists; A fifth step of confirming whether the display size of the receiving terminal can accommodate the size of an image included in the stored multimedia message if it does not exist as a result of the checking of the third step; A sixth step of transmitting an original source image included in the stored multimedia message to a receiving terminal if the fifth step is acceptable; And a seventh step of error processing if the acceptance is not possible in the fifth step.

In addition, the present invention is a computer for downloading the stored multimedia message to the receiving terminal in response to a download request of a specific receiving terminal after storing the multimedia message transmitted from a specific transmitting terminal, the first checking the specification of the receiving terminal step; A second step of checking an image type included in the multimedia message when the stored multimedia message cannot be converted to meet the specification of the receiving terminal; A third step of confirming whether an image file having the same content having a size corresponding to the image type identified in the second step is stored in the database; A fourth step of reading a corresponding image file from the database and replacing the image included in the multimedia message and transmitting the read image file to the receiving terminal, if it exists; A fifth step of confirming whether the display size of the receiving terminal can accommodate the size of an image included in the stored multimedia message if it does not exist as a result of the checking of the third step; A sixth step of transmitting an original source image included in the stored multimedia message to a receiving terminal if the fifth step is acceptable; And a computer-readable recording medium having recorded thereon a program for executing the seventh step of error processing, if it is not acceptable in the fifth step.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to FIG. 2.

In the following description, in describing the method for downloading a multimedia message to a receiving terminal according to the present invention, description thereof will be omitted for general technical contents that may obscure the technical gist of the present invention. And the detailed description according to the present invention described below is only for explaining one example, it will be apparent that those skilled in the art can easily be modified from the technical idea according to the present invention.

2 shows only a network element configuration for transmitting an MMS message to which the present invention is applied.

In the network of FIG. 1, an MMS converter 24 is added.

The subscriber database 22 stores subscriber information of the mobile communication terminal. The subscriber information includes a memory size of the terminal, a screen size for displaying multimedia data, a type of codec for playing multimedia data, and CPU information of the terminal. And version information of the program.

When the MMS server 20 receives a download request for the stored multimedia message from the receiving terminal, the MMS server 20 obtains subscriber information of the receiving terminal from the subscriber database 22. In addition, referring to the specification of the receiving terminal obtained from the subscriber database, the receiving terminal converts the multimedia message into a playable form and transmits the multimedia message to the receiving terminal. At this time, the MMS converter 24 converts the multimedia message.

3A and 3B are diagrams for explaining a method for downloading a multimedia message to a receiving terminal according to the present invention.

When a request for downloading a multimedia message received from the receiving terminal as its destination (101) is received, the MMS server checks (102) the protocol version of the receiving terminal. In addition, as described above, the information of the receiving terminal is obtained from the subscriber database. Thereafter, it is checked whether the MMS message currently stored in the message storage unit is a message that can be converted according to the specifications of the receiving terminal. If the conversion is possible, the multimedia message is converted and transmitted to the receiving terminal as usual (104).

However, if the conversion of the stored multimedia message is impossible, the media type in the multimedia message is checked (105). If the media type is an image, the image size of the SIS format is checked (106). Here, the SIS image may include P08, P09, P10, P11, and P12. As described above, the SIS-type image may be converted in color depth but not in image size. Therefore, depending on the size of the SIS image, it is necessary to save another image corresponding to it in advance. For this reason, images of various sizes for images of the same contents are stored in the database of the content provider CP.

If the SIS image is P10, P11, or P12, the MMS server checks whether there is an image file of size 176 * 144 in the database storing the image (107). In addition, if the SIS image is P08, P09, the MMS server checks whether there is an image file of 120 * 96 premium size in the database storing the image (107). If there is an image file of the corresponding size, the corresponding image file is transmitted to the receiving terminal. If no image file of 176 * 144 size exists, check whether there is an image file of 120 * 96 premium size smaller than this. If there is an image file of 120 * 96 premium size, it is transmitted to the receiving terminal. On the other hand, if the SIS image is of a type other than P08, P09, P10, P11, and P12, check whether there is an image having a file size of 120 * 96 normal. As a result of the check, if there is an image file of 120 * 96 normal size, the image file is transmitted to the receiving terminal after the engine process.

However, if the corresponding image file is not retrieved from the database in which the image file is stored, it is checked whether the receiving terminal can accommodate the size of the original source image file included in the multimedia message (109). If it is confirmed that the acceptance is not possible, error processing is performed (111). However, if it is confirmed that the receiving terminal is acceptable, the original source image included in the multimedia message is transmitted to the receiving terminal after the engine processing (110).

As a result of confirming the media type of FIG. 3A, in the case of audio, a process as shown in FIG. 3B is performed.

First, it is checked whether the audio format included in the multimedia message is an AAC type (112). Where AAC is one of the audio compression types. As a result of the check, if the AAC is supported audio, it is checked whether the AAC codec exists (113). If the AAC codec is present, the multimedia message is transmitted to the receiving terminal together with the AAC codec (114). However, if the AAC codec does not exist, the original source audio included in the multimedia message is transmitted to the receiving terminal as it is (115).

On the other hand, if the audio in the multimedia message is in the MIDI format, it is checked whether there is a sound poly and sound producer for supporting MIDI (116). As a result of the check, if present, the selected MIDI audio file is transmitted to the receiving terminal (117). However, if there are no poly and sound producers to support the MIDI audio file, the source type of the audio is checked (118). As a result of the check, if it is possible to reproduce in the receiving terminal (119), the original source audio included in the multimedia message is transmitted to the receiving terminal as it is (120). However, if the playback is not possible in the receiving terminal as a result of the check, error processing (121).

According to the present invention as described above, when the image or audio file included in the multimedia message can not be converted in accordance with the specification of the receiving terminal, the image or audio that can be played on the receiving terminal image or audio file included in the multimedia message By replacing the file, it is possible to provide a multimedia messaging service between various terminals.
