The present invention relates to a method of a multimedia messaging service, and more particularly, to a method for managing an individual content of a multimedia message for a mobile communication terminal to reuse each content constituting the multimedia message.

Multimedia Messaging Service (hereinafter, referred to as 'MMS') refers to a service that allows a user to send a message in which various media such as pictures, videos, texts, and music are combined to a mobile communication terminal. MMS is expected to be used as the main messaging method that can replace the current SMS (Shot Messaging Service) in the 3rd generation mobile communication network environment. In other words, MMS has evolved from text-based SMS service and EMS (Enhanced Messaging Service) service, which supports simple graphic transmission and reception, to accommodate a variety of media. Users can use wireless postcards, pictures, videos, video cards, You can send and receive maps, business cards, and more. It also supports messages that require broadband, such as cartoons, animations, video ads, and video clips. As such, the MMS enables the transmission and reception of complex multimedia contents, thereby greatly expanding the range of entertainment available for each mobile communication terminal.

A user may create a message with a photo or music using a menu for transmitting an MMS in a mobile communication terminal or connect to a content provider server that provides multimedia content, create a message, and transmit the message to another mobile terminal user. The user who receives the message can immediately check the mobile communication terminal as if the SMS has been received. The MMS may send the length of the transmission message indefinitely, and may be transmitted using a data dedicated network by a pull or push method.

SMIL (Synchronized Multimedia Integration Language) is used for the production and efficient display of multimedia messages. Smile can be defined as a comprehensive language for multimedia based on XML (eXtensible Markup Language) consisting of a few simple tags and attributes, or a multimedia layout language presented by the World Wide Web Consortium (W3C). In other words, Smile is a language that defines the standard and transmission technology necessary for displaying synchronized multimedia contents such as sound, video, text, etc. on the Internet. It is made using XML and is not compiled into a single file. Smile stores multimedia files such as sound, video, and text as a single file on the server, and when executed, the multimedia files are combined to be displayed in the form of multimedia presentation.

By using the smile, it is possible to express the temporal synchronization between the media, express the layout of the space on the screen, add a hyperlink to the media, etc. The smile file includes a head part and a body part. In the head part, static information, area, playback position, etc. (for example, author, title, copyright information, etc.) of the multimedia message are recorded, and in the body part, dynamic information, hyperlink, etc. (for example, file name of the multimedia file) , Storage location, etc.).

As such, in the multimedia message composed of smiles, various multimedia files are individually defined, and at present, each content constituting the multimedia message is not reused. In other words, it is not possible to reuse individual contents included in the multimedia message as a standby screen or to use them as ringtones.

The present invention has been made in view of the above-described disadvantages, and provides a method for managing individual contents of a multimedia message in a mobile communication terminal to individually utilize contents constituting a multimedia message written in a smile form. There is.

The present invention provides an independent ID to each of at least one multimedia content constituting the multimedia message, and when the mobile communication terminal receives the multimedia message, stores the multimedia content constituting the multimedia message by type and stores the multimedia message. A user of a mobile terminal can reuse stored multimedia contents. In this case, it is preferable to distinguish between self-made content and ready-made content. In particular, in the case of ready-made multimedia content authored by the content provider, the multimedia content ID is charged. It is important to include the information so that appropriate charges can be made when reusing.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a view for explaining a communication network configuration for a multimedia messaging service. For convenience of description, the mobile communication terminal will be divided into a mobile communication terminal 10 capable of supporting MMS and a mobile communication terminal 20 capable of basic WAP service. In addition, the MMS message may be transmitted and received using a wired terminal or a mobile communication terminal. In the present invention, the receiving terminal is a mobile communication terminal, regardless of the type of the transmitting terminal.

The mobile communication terminal 10 supporting the MMS is capable of creating, receiving, and presenting an MMS message, and has a function of storing and managing an MMS message. It also performs functions such as encryption of MMS messages, terminal capability information exchange, and user information management. In order to exchange the terminal performance information, the performance is determined according to the terminal type and the performance information of the terminal is stored in the user profile.

The MMS support mobile communication terminal 10 is provided with an MMS client for MMS support, and a user directly composes a multimedia message using multimedia contents by a function (camera, built-in sound, etc.) of the mobile communication terminal 10. Alternatively, a message may be created by accessing various content provider servers 130 that provide multimedia contents through the mobile communication network 30. In this case, the MMS message may be written in a SMIL (Synchronized Multimedia Integration Language) format by an MMS client installed in the terminal. The MMS client refers to a solution that enables mailing services by creating and editing photos and pictures in the format desired by the user through image editing, sound editing, and video editing.

The MMS message may be written using the personal computer 60 as well as the mobile communication terminal 10. In this case, the MMS client creates a smiley MMS message using the multimedia content owned by the user or accesses various CP servers 130 through the Internet 50 to select the desired multimedia content and uses the same. You can create MMS messages in smile format. The MMS message thus prepared is transmitted to the receiver's terminal through the MMSC 40 using the email server 110 and the voice mail server 120. That is, the email server 110 and the voice mail server 120 transmits the MMS message sender to the MMSC 40 when the MMS message sender wants to compose and transmit the MMS message by email or voice mail using the personal computer 60. After receiving this, the MMSC 40 converts the message format and transmits the MMS message to the corresponding mobile communication terminal.

The MMS message created in the mobile communication terminal 10 or the personal computer 60 may be transferred to another mobile communication terminal (MMS-supporting terminal or a general terminal; 10, 20) user and the personal computer 60 through the multimedia messaging service center (MMSC, 40). ) Can be sent to the user.

The MMSC 40 is responsible for the transmission and reception of MMS messages, performs message format conversion (WML <-> HTML) and address format conversion, and performs an SMS transmission function for notifying the mobile terminal of the message reception. In addition, it generates and transmits various guide messages (receipt confirmation, transmission confirmation, etc.) to MMS message transmission and reception terminals, respectively, and has an MMS message storage and management function. In addition, it supports billing data generation, performance information exchange of mobile communication terminals, MMS message delivery function, address hiding function, multimedia format and type conversion function, and MMS message screening function.

The MMSC 40 consists of an MMS relay 410 and an MMS server 420. The MMS relay 410 is an MMS message exchange device that provides a real-time multimedia exchange function, and establishes connection / resource management / resource between MMS message transmission and reception terminals. It performs the release function and MMS message notification function. Meanwhile, the MMS server 420 performs a real time streaming function of the MMS message, a function of storing and managing a multimedia message in a database, and a push function for notifying reception of the MMS message.

To this end, the MMSC 40 preferably shares the short message service center (SMSC) 70, the subscriber database 80, the home location register (HLR) 90, and the charging system 100 with the mobile communication system. 50 is connected to various email servers 110, voice mail server 12 and content provider server 130 on the Internet.

The SMSC 70 is responsible for notifying the user who has received the MMS message by the text message of the MMS reception, and the subscriber database 80 and the HLR 90 manage and provide profile information of the MMS subscriber, and transmit and receive the MMS message. Information management (message delivery, etc.) related to the service, service performance information (server storage space, etc.) that can be provided, and performance information storage of a terminal currently being used are performed.

The billing system 100 generates and manages billing information according to the multimedia content usage history and transmission history for the user of the mobile communication terminal 10 that creates and / or transmits the MMS service. Since the interface and protocol conversion between the MMSC 40 and each terminal and each component does not fall within the scope of the present invention, a detailed description thereof will be omitted.

2 is a flowchart illustrating a general multimedia messaging service method.

A user who wants to send an MMS message to a mobile communication terminal may create an MMS message by using the authoring tool of the mobile communication terminal MS ₀ or a personal computer PC or by accessing the CP server 130 (see FIG. S101). In this case, it is preferable to write a message in a smile form using an MMS client.

After the MMS message is created, the MMS message is transmitted to the MMSC 40 by the message transmission request (S102), and the MMSC 40 checks the sender information, the receiver information, and the like, and notifies the receiver of the reception of the MMS message. At this time, the MMSC 40 composes the acknowledgment message as a text message and transmits the received acknowledgment message to the receiving side mobile communication terminal MS _T through the SMSC 70 (S103 and S104).

The user of the mobile communication terminal receiving the text message notifying the reception of the MMS message requests to download the message by accessing the MMSC 40, and the MMSC 40 converts the message format according to the type of the receiving terminal MS _T. After downloading the MMS message (S107). At this time, to determine if the recipient mobile communication terminal (MS _T) to play a message to download system whether to play the message to the streaming method according to the user's request, to download the MMS message according to the user's request.

Thereafter, each content included in the MMS message is stored for each type in the receiving side mobile communication terminal MS _T (S108). After the content storage is completed, the MMS message is reproduced (S109). When the MMS message is provided in a download manner, each content constituting the MMS message is stored in a specific memory area of the mobile communication terminal even after message playback is completed.

When the MMS supporting terminal that has received the MMS message wants to store the MMS message, the MMS supporting terminal extracts at least one or more Content IDs included in the MMS message from the smiley MMS message and then sorts the content (text, image, video). Save the content, sound, etc.). The MMS message is reproduced by a message reproducing method included in a smile type MMS message according to a user's request. At this time, in order to enable later reuse of various contents constituting the MMS message, the content ID is newly defined.

The multimedia content used in the MMS message can be divided into self-made content created by the user and ready-made content provided by the content provider. May be transmitted to and used by various receiving terminals, and in some cases, duplicate content is received. Therefore, if the multimedia content included in the MMS message is managed to be referred to as its own file, it can be reused such as retransmission to other recipients and storage as wallpaper. At this time, if the multimedia content is content provided from the CP server, it is also necessary to charge for using the content.

3 is a view for explaining the field configuration of the content ID for the multimedia messaging service according to an embodiment of the present invention, which shows the field configuration of the multimedia content ID provided from the content provider server.

In order to manage the multimedia content as an original file, the content ID is composed of 22 digits. Content provided from the CP server has the configuration as shown in FIG. That is, the author identification code 1 digit, retransmission 1 digit, CP classification code 5 digits, billing information 5 digits, content identification code 10 digits.

In this case, the author identification code field indicates a business operator identification code by using numbers other than 0 in the case of ready-made content, and the retransmission availability field is 0 when retransmission is impossible and 1 when retransmission is possible. The CP identification code field indicates a content provider ID that produced the corresponding content, the charging information field indicates a content amount, and the content identification code field indicates a content identification number uniquely assigned to each content provider. In the example of FIG. 3, the business operator identification code is 1 and retransmittable. The ID of the content provider is 34256, the content amount is 300 won, and the content identifier is 1234567890. That is, the content ID shown in FIG. 3 is '1134256003001234567890'.

The multimedia content provided by the content provider is made in such a way as to assign billing information and content identifier for each content provider. However, in the case of self-made content, the billing item may be omitted and the content may be classified by terminal.

FIG. 4 is a diagram illustrating a field configuration of a content ID for a multimedia messaging service according to another embodiment of the present invention, and illustrates a field configuration of a multimedia content ID directly written by a user.
