The present invention relates to a service for generating and transmitting an MMS legacy message so that a multimedia messaging service (MMS) legacy terminal can play a long MMS message. More specifically, when a long MMS message is received from an originating terminal, when the destination mobile communication terminal is an MMS legacy terminal, it is divided into a frame animation image so that the long MMS message can be played like the MMS client terminal. The present invention relates to a service providing method of converting and generating an MMS legacy message and transmitting the generated MMS legacy message.

With the rapid development of electronic engineering and communication engineering, mobile communication terminals have various functions. That is, with the rapid development of wireless communication and data communication technology, people can use not only voice calls but also Internet access, video communication and video message transmission using mobile communication terminals. Also, due to the rapid spread of mobile communication terminals, mobile communication terminals are becoming an essential means of communication in modern life, such that a great amount of communication between remote sites occurs through mobile communication terminals.

 In recent years, among various functions of the mobile communication terminal, not only the area or state in which a call is available, but also the case in which the call cannot be connected due to the case where the other party has left the mobile communication service area or the mobile terminal is turned off, etc. Short message service (SMS) or voice message service (VMS) that can deliver a message or voice message to the other party is widely used.

On the other hand, the short message service or voice message service is difficult to meet the various needs of the user because it can transmit a simple text or voice message to the other party. For this reason, in recent years, in order to satisfy the desire of mobile subscribers to transmit multimedia messages such as pictures, images, and videos other than simple text or voice messages, multimedia messaging service (MMS) is hereinafter referred to as 'MMS'. ) Is actively used.

MMS refers to a messaging service that transmits and receives multimedia information by processing, converting, and selecting data in various formats to be suitable for various multimedia service environments. The MMS provides a function of transmitting and receiving multimedia information and e-mail to various devices desired by an e-mail user, away from a limited integrated service based on text or voice provided by a conventional Unified Messaging Service (UMS).

1 is a block diagram schematically illustrating a system for providing a conventional multimedia messaging service.

The conventional system for providing a multimedia messaging service includes an outgoing mobile terminal 110, a mobile communication network 120, a calling user terminal 130, the Internet 140, an e-mail server 142, and a multimedia messaging service center (MMSC). Multimedia Messaging Service Center, hereinafter referred to as 'MMSC') 150 and the terminating mobile terminal 160.

The outgoing mobile terminal 110 generates a multimedia message through a key manipulation inputted from the caller and transmits the multimedia message to the MMSC 150 using the mobile communication network 120 to transmit to the destination mobile terminal 160. Therefore, the outgoing mobile terminal 110 has a built-in program for composing a multimedia message, and has a communication means for performing wireless communication with the mobile communication network 120.

The mobile communication network 120 includes a wireless base station 122, a mobile communication switching center (not shown), a data core network (DCN) 124, and a home location register (HLR) (not shown). The mobile terminal 110 performs various functions for performing a mobile communication service. The wireless base station 122 performs a location registration function, a function of allocating a radio channel, and various functions required for radio call processing such as handoff. A mobile communication switching center (not shown) performs basic and additional service processing for providing a voice communication service, incoming and outgoing call processing of a subscriber, location registration procedure and handoff procedure, and interworking with other networks. A home location register (not shown) is a database that stores a service profile of mobile subscriber information, including a subscriber's telephone number, a mobile identification number (MIN) of the mobile communication terminal 110, and a terminal unique. Stores subscriber information by storing information about Electronic Serial Number (ESN) and service type. The data core network 124 may include a high speed data service for providing a packet data communication service, an internet / intranet access service, a virtual private network (VPN) access service, a simple IP and a mobile IP service, Performs Point-to-Point Protocol (PPP) authentication, billing, and packet compression.

The calling user terminal 130 creates a multimedia message through key manipulation inputted from the user and uses the MMSC 150 using an e-mail server 142 connected to the Internet 140 together with the phone number of the called mobile communication terminal 160. A computer or the like, which is a computer to be transmitted, may be any one of a desktop computer and a notebook computer, and has a built-in web browser for connecting to the Internet 140.

The Internet 140 refers to a global open computer network architecture that provides the TCP / IP protocol and various services that exist in the upper layers, namely HTTP, Telnet, FTP, DNS, SMTP, SNTP, NFS, and NIS. In addition, the Internet 140 includes an electronic mail server 142 for transmitting the multimedia message received from the calling user terminal 130 to the destination mobile communication terminal 160.

The electronic mail server 142 is connected to the MMSC 150 via the Internet 140 to perform a function of transmitting an MMS message in an electronic mail format to the destination mobile communication terminal 160 using the MMS. The e-mail server 142 transmits and receives e-mails using SMTP (Simple Mail Transfer Protocol), which is a type of TCP / IP protocol, for transmitting e-mails.

MMSC 150 is a core component of MMS system including MMS server 152, MTS server 152, Media Transcoder Server (MTS) 154 and MMS database 156. As a component, it performs the function of sending and receiving messages between different messaging systems. Sending the multimedia message received from the calling mobile terminal 110 or the calling user terminal 130 to the called mobile terminal 160 using the mobile communication network 120 using the information of the called mobile terminal 160. do.

Here, the MMS server 152 manages and controls the MTS 154 and the MMS database 156 to transmit multimedia messages between mobile communication terminals, between user terminals, and between mobile communication terminals and user terminals. The MTS 154 converts wired and wireless multimedia data to each other. That is, for example, converting HTML (Hypertext Markup Language) text or the like into XML (Extensible Markup Language) text or the like, or converting a wired WAV or MP3 audio file into a wireless QCELP (Qualcomm Code Excited Linear Prediction) audio file or the like Converts wired image files such as Joint Photographic Expert Group (JPG) or Graphic Interchange Format (GIF) into wireless Simple Image Service (SIS) image files.

In addition, the MMS database 156 not only stores multimedia messages received by the MMS server 152, but also MIN (Mobile Identification Number), ESN (Electronic Serial Number), and user profile information of an MMS client terminal capable of using MMS. And various service information available.

The destination mobile communication terminal 160 receives and plays a multimedia message from the MMSC 150 using the mobile communication network 120. Therefore, the terminating mobile communication terminal 160 has a program for reproducing the received multimedia message.

In the conventional MMS system, the terminating mobile communication terminal 160 receives and plays a multimedia message received from the calling mobile communication terminal 110 or the calling user terminal 130 using the MMSC 150 as described above. Programs and hardware should be in place. That is, the called mobile communication terminal 160 should be an MMS client terminal.

Meanwhile, the incoming mobile communication terminal 160 is a terminal capable of reproducing a message such as a text and a voice, but generates a multimedia message written in a long sentence using a pictogram, a color text, a background color, a background image, and the like. In the case of a terminal that is not a reproducible MMS client terminal (hereinafter referred to as an 'MMS legacy terminal'), the MMS message may not be received and may not be reproduced even when received.

As described above, the MMS message may be written in a long text by adding various effects such as pictogram, color text, background color, and background image to simple text. Such pictograms, color texts, background color images, etc. may be converted into a media format (eg, SIS file format) usable by the mobile communication terminal using the MTS 154, and may have an effect in the MMS legacy terminal. However, MMS legacy terminals do not have a means to play long text MMS messages.

Accordingly, there is a demand for a technology capable of providing a multimedia environment to a mobile subscriber regardless of the type and specification of the mobile terminal by converting the long MMS message so that the MMS legacy terminal can reproduce the long MMS message.

In order to solve this problem, the present invention, when receiving a long MMS message from the originating terminal so that even in the MMS legacy terminal to play the long MMS message to determine whether the destination terminal is the MMS legacy terminal to receive the long MMS message Service converts long text MMS message into animation image divided into multiple frames in the process of converting to playable media format, and adds dummy data to the called terminal if necessary.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First of all, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are used as much as possible even if displayed on different drawings. In addition, in describing the present invention, when it is determined that the detailed description of the related well-known configuration or function may obscure the gist of the present invention, the detailed description thereof will be omitted.

In addition, hereinafter, the present invention is applied to a system for providing a multimedia messaging service described with reference to FIG. 1 and will be described by dividing into one embodiment and a second embodiment. Here, the first embodiment relates to a method for providing a service capable of reproducing a long MMS message even in an MMS legacy terminal, and the second embodiment is a long MMS message so that the MMS legacy terminal can play a long MMS message. The present invention relates to a method of generating an MMS legacy message which is a split frame animation image.

2 is a flowchart illustrating a method of providing an MMS legacy message service for an MMS legacy terminal according to a first embodiment of the present invention.

In the system for providing a multimedia messaging service described with reference to FIG. 1, the outgoing mobile terminal 110 creates a long MMS message through a key manipulation inputted from a mobile subscriber, thereby creating a MIN (Mobile) of the incoming mobile terminal 160. Identification Number) and transmits to MMS server 152 using mobile communication network 120. Alternatively, the calling user terminal 130 creates a long MMS message through a key manipulation inputted by the user and uses the e-mail server 142 connected to the Internet 140 together with the MIN of the called mobile communication terminal 160. The transmission is sent to the MMS server 152 in a mail format (S210).

The MMS server 152 that has received the long MMS message from the calling mobile terminal 110 or the calling user terminal 130, receives the MIN of the receiving mobile communication terminal and the MIN of the MMS client terminal stored in the MMS database 156. To compare (S220). In addition, it is determined whether the incoming mobile communication terminal 160 is an MMS legacy terminal by using the comparison result of step S220 (S230). Here, the MMS server 152 communicates with the mobile communication network 120 at random intervals to check whether or not the incoming mobile communication terminal 160 is an MMS legacy terminal. MIN of the mobile communication terminal registered in) is received and updated in the MMS database 156.

On the other hand, the MMS server 152, as a result of the determination in step S230, when the terminating mobile communication terminal 160 is an MMS client terminal other than the MMS legacy terminal, the procedure is terminated and transmits the MMS message in a conventional MMS providing method. As a result of the determination of step S230, the MMS server 152 uses the media conversion server (MTS: Media Transcoder Server, hereinafter referred to as MTS) when the terminating mobile communication terminal 160 is an MMS legacy terminal. The method of generating 'converts the long text MMS message to the' MMS legacy message '(S240). In the present invention, the 'MMS legacy message' refers to a split frame animation image obtained by dividing an image converted into a format suitable for a mobile communication terminal into a plurality of frames so that a long MMS message can be reproduced in an MMS legacy terminal. A detailed description of how the MTS 154 converts a long MMS message to generate an 'MMS legacy message' will be described with reference to FIG. 2 in a later process.

The MMS server 152 converting the long text MMS message into the 'MMS legacy message' using the MTS 154 transmits to the destination mobile communication terminal 160 using the mobile communication network 120. The called mobile communication terminal 160 plays the received 'MMS legacy message' (S260). In the present invention, by converting a long MMS message into an 'MMS legacy message' and transmitting the long MMS message in the MMS legacy terminal as well as outputting the natural effects indicated by the long MMS message on the screen.

3 is a flowchart illustrating a method of generating a 'MMS legacy message' by converting a long text MMS message according to a second embodiment of the present invention.

As described with reference to FIG. 2, when the terminating mobile communication terminal is an MMS legacy terminal in step S240, a long MMS message is converted using the MTS 154 to generate an 'MMS legacy message'. At this time, the MTS 154 generates one animation image using text information including pictogram, color text, background color, background image, and the like included in the long text MMS message received from the MMS server 152. (S310).

The MTS 154 that generates one animation image determines whether the data size of the animation image is smaller than the data size of the general image (S320). If the data size of the animated image is smaller than the data size of the normal image, the MTS 152 inserts dummy data into the animated image to increase the data size of the animated image to the data size of the normal image. (S330).

In the present invention, when the data size of the animated image is smaller than the data size of the general image, the reason for inserting dummy data into the animated image will be described later. The data size of an MMS message depends on the size of multimedia data such as pictograms, colored text, background colors, and background images rather than the size of text data. That is, the data size of an MMS message that includes long text information, but lacks multimedia information such as a background color and a background image, is a data of an MMS message that includes text information of a short sentence but has a lot of multimedia information such as a background color and a background image. It can be relatively smaller than size.

Typically, MMS legacy terminal can output the animation image of 6 ~ 20 kbytes on the screen, if it is smaller or larger than this can not be output to the screen. As a result, when the data size of the animated image including the long text information but the multimedia information such as the background color and the background image is weak is 5 kbyte or less, the MMS legacy terminal displays the animated image on the screen. There is a problem that cannot be printed. Therefore, in the present invention, by inserting dummy data into the animated image, the data size of the animated image is increased to 6 kbytes or more, which is the data size of the general image, so that the MMS legacy terminal can output the animated image data to the screen. This solves a problem that may occur in the process of reproducing animation image data in the MMS legacy terminal. Here, the dummy data is hidden additional data that does not affect the contents of the animated image and is not output to the screen at the time of reproduction.

If the data size of the animated image is greater than or equal to the data size of the normal image, the MTS 152 proceeds to step S340 in which the animated image is divided into one or more frames to divide the frame animation image. Create

The MTS 152 inserting dummy data into the animation image in step S330 generates a split frame animation image by dividing one animation image into one or a plurality of frames (S340). The reason for dividing one animation image into one or a plurality of frames in the present invention is as described below. One animation image generated in step S310 is converted into a media format that can be played on the MMS legacy terminal, but cannot be output on the screen of the MMS legacy terminal. This is because the MMS legacy terminal cannot output an animation image larger than a certain size on the screen. Therefore, in the present invention, one animation image generated in step S310 is divided into a plurality of frames having a predetermined size, as in step S340. That is, for example, assuming that an animation image has a size of 128 X 288 pixels (Pixels), and that an MMS legacy terminal can output an animation image of 128 X 96 pixels on the screen, a 128 X 288 pixel size is determined. One animated image is divided into three frames having a size of 128 x 96 pixels.

In step S340, the MTS 154 that generates a split frame animation by dividing one animation image and inserts serial number information and frame repetition information into each frame of the split frame animation image (S350).

In the present invention, the reason for inserting the serial number information into each frame of the divided frame animation image is as follows. The MMS server 152 receives the MMS legacy message, which is a split frame animation image, from the MTS 154 and transmits the MMS legacy message to the destination mobile communication terminal 160 using the mobile communication network 120. At this time, since the split frame animation image 'MMS legacy message' is composed of a plurality of frames as described above, it is not guaranteed that the terminating mobile communication terminal 160 receives the plurality of frames sequentially. Therefore, the terminating mobile communication terminal 160 receives the split frame animation image once, checks the serial number information attached to each frame of the split frame animation, and reproduces the serial number information.

In the present invention, the reason for inserting the repetition information in each split frame animation image is as described later. In general, the MMS client terminal sets an arbitrary delay time between frames in the process of playing a long MMS message so that the mobile subscriber can read the long MMS message. On the other hand, most MMS legacy terminals can not play each frame by setting the above-described random delay time. Accordingly, in the present invention, the message can be read to the mobile subscriber by adding an effect of setting the aforementioned arbitrary delay time without increasing the size of the divided frame animation image by repeatedly playing a predetermined frame for a predetermined time. It gives you time to spare.

Accordingly, in the present invention, the serial number information is attached to the split frame animation image so that the terminating mobile communication terminal 160 can play the split frame animation image in the correct order, and the frame repeating information is repeatedly reproduced for a predetermined time. attach. In addition, typically, the receiving mobile communication terminal 160 checks the serial number information attached to the received split frame animation image and plays it with the serial number, and checks the repeating frame information to repeatedly play the frame for a predetermined time. It has a built-in program.

As described above, through the procedure of steps S310 to S350, the MTS 154 converts the long MMS message to generate a 'MMS legacy image' which is a split frame animation image.

The above description is merely illustrative of the technical idea of the present invention, and those skilled in the art to which the present invention pertains may make various modifications and changes without departing from the essential characteristics of the present invention. Therefore, the embodiments disclosed in the present invention are not intended to limit the technical idea of the present invention but to describe the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments. The protection scope of the present invention should be interpreted by the following claims, and all technical ideas within the equivalent scope should be interpreted as being included in the scope of the present invention.

As described above, according to the present invention, even in an MMS legacy terminal that cannot reproduce a long MMS message, a long MMS message created using a pictogram, color text, a background color, a background image, etc. can be reproduced using the original multimedia effect. . In addition, it is possible to reduce the transmission and reception of unnecessary messages generated because the MMS legacy terminal was not able to reproduce the long MMS message.
