2 is a flowchart illustrating a message transmission method using a connection message according to an embodiment of the present invention.

First, the calling terminal 10 generates a block message and transmits a block message to the multimedia message service center 55 (S210).

The multimedia message service center 55 inquires the subscriber database server 52 or the home location register 53 of information of the called terminal 20 (S212). Here, the information of the called terminal 20 includes information on whether the called terminal 20 is a terminal capable of supporting a block message. The subscriber database server 52 or the home location register 53 transmits the information of the called terminal 20 to the multimedia message service center 55 (S214).

The multimedia message service center 55 receiving the information of the called terminal 20 determines whether the called terminal 20 is a block message supporting terminal (S220). If the block message support terminal, the multimedia message service center 55 transmits a block message to the destination terminal 20 (S225).

If the called terminal 20 does not support the block message, the multimedia message service center 55 converts the block message to the block message converter 47 and generates a block message along with a request for generating the connection message. Is transmitted to the block message converter 47 (S230).

The block message converter 47 generates a connection message by converting the received block message (S240). The connection message refers to a message generated by dividing a block message into sub-block messages having a predetermined size. For example, when the predetermined size corresponds to the size of the short message, it may be set to 90 bytes. However, the size of a short message of 90 bytes is only one example. In addition, each subblock message may include a delimiter, and the order of each subblock message may be determined.

When the connection message is generated, the block message converter 47 transmits the connection message to the called terminal 20 (S250 and S260). For example, if the sub-block message corresponds to a short message, the block message converter 47 delivers each sub-block message to the short message service center 45, and the short message service center 45 is the destination terminal ( 20) each subblock message is transmitted (S250, S260).

After receiving each subblock message, the called terminal 20 connects each subblock message to generate one message and display the message on the screen (S270). Each subblock message is distinguished by a delimiter, and the called terminal 20 may regenerate the block message using the delimiter. However, the regenerated block message is generally the same as the block message transmitted by the originating terminal 10, but may be different.

When the connection message transmission is made, the block message converter 47 may report the transmission progress to the calling terminal 10 (S280).

As described above, according to an embodiment of the present invention, the block message converter 47 may transmit the block message to the destination terminal 20 that does not support the block message.

3 shows a block diagram of a block message converter according to an embodiment of the present invention. Referring to FIG. 3, the block message converter 47 according to an embodiment of the present invention may include a message receiver 310, a connection message generator 320, and a message transmitter 330.

The message receiving unit 310 serves to receive a block message transmitted from the calling terminal 10. The calling terminal 10 transmits a block message to the multimedia message service center 55, and the multimedia message service center 55 delivers a block message to the message receiving unit 310 of the block message converter 47. In general, the originating terminal 10 transmits a block message to the base station 22 through a wireless channel, so that the base station 22 transmits the block message to the multimedia message service center 55 in the cabled core network 60. do.

Meanwhile, the multimedia message service center 55 may inquire the subscriber database server 52 or the home location register 53 whether the terminating terminal 20 is a terminal capable of supporting a block message and receive a response. In addition, the multimedia message service center 55 receives data size information that the calling terminal can receive from the subscriber database server 52 or the home location register 53 when the called terminal 20 is a terminal that cannot support the block message. Can be obtained.

The connection message generator 320 generates a connection message by dividing the received block message into one or more subblock messages. The sub block message refers to a message of a size that can be received by the calling terminal. Each subblock message includes a delimiter indicating an individual order, and each subblock message may be referred to as a connection message. Therefore, by dividing the block message into one or more sub-block messages that the terminating terminal 20 can receive, the block message can be also transmitted to the terminating terminal 20 that does not support the block message.

The message transmitter 330 transmits the generated connection message to the called terminal 20. The message transmitter 330 may transmit each subblock message to the called terminal 20, and the called terminal 20 may receive each subblock message. For example, if the subblock message is the same as the short message, the message transmitter 330 delivers each subblock message to the short message service center 45, and the short message service center 45 sends each subblock message. It transmits to the called terminal 20.

4 is an exemplary diagram in which a block message is divided into sub-block messages according to an embodiment of the present invention. Referring to FIG. 4, the block message 400 may be separated into one or more sub-block messages 410_1, 410_2, and 410_3 by the block message converter 47.

For example, if the sub block messages 410_1, 410_2, and 410_3 are short messages having a predetermined size, the sub block messages may be generated as much as the data size of the general short message.

Each subblock message 410_1, 410_2, and 410_3 may include a separator field 420, an originating terminal field 440, a called terminal field 450, and a message field 430. Each sub-block message 410_1, 410_2, and 410_3 may be referred to as one and may be referred to as a concantenation message.

Therefore, after the block message 400 is divided into one or more sub-block messages 410_1, 410_2, and 410_3, each sub-block message 410_1, 410_2, and 410_3 is transmitted to the called terminal 20. The called terminal 20 connects the sub-block messages 410_1, 410_2, and 410_3 to the screen of the called terminal 20 to display the block message transmitted from the calling terminal 10 to the called terminal 20 as it is. Can be.

5 is another exemplary diagram in which a block message is divided into sub-block messages according to an embodiment of the present invention. Referring to FIG. 5, the block message 500 may be divided into one or more subblock messages 510_1, 510_2, and 510_3 by the block message converter 47. Here, each subblock message is referred to as a first subblock message 510_1, a second subblock message 510_2, and a third subblock message 510_3.

For example, when the block message 500 is a multimedia message including a video image and text, the video message cannot be delivered to the called terminal 20. This is because the called terminal 20 is a terminal that does not support the block message.

According to an embodiment of the present invention, when the block message 500 is a multimedia message including a video image and text, the text is extracted and transmitted to the called terminal 20. For example, when the video image and the text are separated, the text may be extracted, and metadata information such as a file name, a file size, and a file creation date of the video image may be extracted from the video image.

Accordingly, text is generated as each subblock message according to the data size of the subblock, and a predetermined subblock message composed of text is generated based on the extracted information about the video image. For example, as shown in the third sub-block message 510_3, information about a file name, a size, a date, and the like of the image of the block message 500 may be extracted to be a sub-block message 510_3.

After each of the sub-block messages 510_1, 510_2, and 510_3 is separated into the block message converter 47, each of the sub-block messages 510_1, 510_2, and 510_3 is transmitted to the destination terminal 20. The called terminal 20 connects each subblock message 510_1, 510_2, and 510_3 to generate one message 570 and display it on the screen. However, the message 570 displayed on the called terminal 20 is a message including the picture image from the block message 500 including the picture image, and instead of the picture image.
