The present invention relates to a mobile communication technology, and more particularly, to a message generating method for a multimedia messaging service (MMS) commonly used in a mobile communication terminal.

Mobile communication has greatly changed and changed everyday life in accordance with the universalization of its dissemination in terms of being able to supply and exchange necessary information anytime and anywhere due to its portability. Furthermore, in the early stages, the aspect of information exchange was emphasized, but the importance of the cultural exchange aspect for providing contents is more and more emphasized.

The communication technologies currently supported by mobile communication can be divided into voice communication, messaging service, and wireless internet service. With the exception of traditional voice communications, wireless content in messaging and wireless Internet services is often written separately from wired content because the screen size or resolution of the client is different. But tools for creating wireless content are less common than tools for creating wired content, and experts are still lacking.

Accordingly, it is an idea of the present invention to create wired contents for wireless clients and convert them to wireless contents. In connection with the conversion between wired and wireless contents, the present invention and concept are completely different, but Korean Patent Laid-Open Publication No. 2000-67044, which was invented by Kim Gap-soon et al. The present invention discloses a technique for converting, compressing, storing, storing, and transmitting the document to the requesting wireless client. This technology is similar in technology to the present invention in that wired content is provided to a wireless client, but mainly focuses on data compression in consideration of differences in transmission speeds of wired and wireless networks. It does not conceive or disclose specific techniques for overcoming formal differences.

Another related art is Korean Patent Laid-Open Publication No. 2003-38325, which was invented by Kim Jae-hyung, Hong Jong-cheol, etc. and published on May 16, 2003. This document discloses a technique for uploading and viewing multimedia contents by accessing a web bulletin board through a wireless network. However, this document only lists the overall system configuration and current status of standards, and does not touch specific content conversion technologies. This well-known technique does not approach document conversion related to the transmission of messages.

Another related art is Korean Patent Publication No. 2003-35249, which was invented by Yu Ho Kyung and published May 5, 2003. This document discloses a system for receiving a short message, analyzing the text, converting the text into multimedia data, and converting the text into a multimedia message. This document outlines the construction of a multimedia message, but the idea of overcoming the inconvenience caused by the system differences of wired and wireless networks such as the present invention is not seen.

The present invention has been proposed in this background, and an object thereof is to make it possible to more conveniently compose a multimedia message that can be viewed in a mobile communication terminal.

The message is transmitted to a designated receiving terminal via a mobile communication network. At this time, the obtained component files are converted into a file in a text format, and they are reconstructed into a multimedia message in a multi-part format by adding a head along with the first document.

According to this aspect of the present invention, the multimedia message may be conveniently written by a well-known wired content creation tool and then converted and transmitted to the message receiver.

According to an auxiliary aspect, this conversion method can be performed independently on a personal computer connected on the network. At this time, the identification number of the receiving terminal and the location information where the web document is stored are input. Accordingly, the document is obtained, converted, and sent to the designated recipient. Additionally, the web document creation tool is provided in connection with or integrated with the software according to the present invention, so that the present invention can be used more conveniently for the user.

According to another auxiliary aspect, this conversion method may be performed in a service server connected on a network. At this time, the identification number of the receiving terminal and the location information where the web document is stored are input from the client computer connected to the service server through the network. Accordingly, the document is obtained, converted, and sent to the designated recipient.

In accordance with this aspect of the invention, the invention may be implemented in such a way that it serves a number of users.

The network connection unit 130 is a concept encompassing a TCP / IP layer, a physical layer, and network adapter hardware, which is an HTTP lower layer in an embodiment. The mobile terminal 11 may communicate with the mobile communication terminal 11 via a gateway of the wireless communication network 70 through the TCP / IP layer.

 The protocol processing unit 110 may receive and process not only a web document located on the web but also a file stored locally, another application program, or another module of the same program, for example, a document edited in a web document authoring tool or an authoring module.

The parser 300 receives a text string written in a markup language from the protocol processor 110 such as the HTTP protocol, and tokenizes the document. Tokenizing is the creation of tokens such as tags, attributes, and text with promised characters like the '<' and '>' symbols. Construct a DOM tree with tokens created through analysis. The DOM Tree is created according to the w3c (World Wide Web Consortium) standard. When the DOM Tree is completed, the DOM Tree is assigned an attribute (attribute value).

The object acquirer 500 receives the DOM Tree from the parser 300 and creates a list of files connected to the document. This list includes location information, eg, URLs, to which individual component files can be accessed. For example, all files other than the file associated with the <a> tag can be included in the file to be downloaded. For example, these files can include video (mpeg, mov, avi, asf, ram, dat), sound (mp3, asx, vqf, wav, mid), images (gif, jpg, pic, bmp, tif), compressed files ( zip, rar, tgz, arj, cab, tar, ace), executable (exe), document file (hwp, doc, txt, pdf, ps, xls, ppt) and the like.

FIG. 5 is a diagram schematically showing an overall configuration of a system to which a multimedia message service device according to another embodiment of the present invention is applied. As shown, in the present embodiment, the multimedia message service apparatus according to the present invention is implemented as a personal computer 13, and corresponds to MMS proxy relays of multimedia message servers (MMSCs) of a plurality of mobile carriers subscribed to by a receiver. Are connected via the fields 31 and 33.

MMS proxy relays 31 and 33 are defined in the Open Mobile Alliance standard OMA-MMS-ARCH-v1_2-20030920-C. The MMSC 20 is also an MMS server defined in the above standard. The MMSC 20 stores and buffers the MMS message and transmits the MMSC 20 to the mobile communication terminals 11 and 15 through the mobile communication network in conjunction with the base station of the wireless communication network. The mobile communication terminal is a terminal capable of receiving a multimedia message through a mobile communication network. For example, the mobile communication terminal may be a mobile phone or a PDA capable of mobile communication.

7 is a flowchart schematically showing the overall configuration of a method for transmitting a multimedia message according to an embodiment of the present invention. As shown, the multimedia message transmission method according to an embodiment of the present invention comprises the steps of acquiring a first document in a markup language format commonly used in a wired network (S103), parsing the first document (S105), and parsed the Acquiring the location information of the component files including the image and / or audio file referred to in the first document from the result, and acquiring the corresponding component files using the location information (S107); A reconstruction step (S111) of reconstructing the first document file and the component files into a multimedia message that can be viewed by a mobile communication terminal, and transmitting the reconstructed message to a designated receiving terminal via a mobile communication network (S113). It is composed.

First, identification information of the receiver terminal, for example, a phone number and location information where a web document is stored, is obtained (step S101). In one embodiment, this information is obtained from the user's client computer, and the location information of the web document is the network address where the web document to be converted is stored. In another embodiment, the location information of the web document can be path information of a local directory of the client computer. A plurality of identification information of the receiver terminal may be input in a list for broadcast transmission. In this case, it is possible to additionally receive the adaptation information for the changed portion of the message, for example, the name or address, for each identification number of the receiving terminal.

Next, the web document is obtained from the obtained position information (step S103). In one embodiment, the web document handled by the present invention is a document written in a protocol commonly used in a wired network such as HTTP, but at a resolution suitable for display on a screen of a mobile communication terminal. In this case, the web document may be obtained by accessing the web document using a network address which is obtained location information. If there is adaptation information, the web document may include identifiers between the adaptation information contracted according to the present invention. For example, a document may be generated with the name field %% name and the address field %% address.

Next, the obtained web document is parsed and the components are analyzed (step S105). Based on the analysis, the location and filename of the image, audio, and video files linked to this document are identified. Thereafter, these component files included in the web document are obtained using this information (step S107).

Next, a process of converting the obtained web document into a markup language file for a messaging service of a mobile communication network may be required. Examples of markup languages of mobile communication networks include WML (Wireless Markup Language), SMIL (Synchronized Multimedia Integration Language), and the like. Although MMS service supports various types of markup languages, some mobile operators may only support protocols other than HTTP. In this case, conversion is necessary. However, if the receiving terminal supports the HTTP protocol, the conversion of the text web page itself is unnecessary.

Furthermore, component files such as image and / or audio files may be compressed and then converted into a format that is advantageous for output from the mobile communication terminal (step S109). Since the compression algorithm of the multimedia files is known in various formats, a detailed description thereof will be omitted.

The obtained component files are converted to a file in a text format immediately after being compressed. This is because MIME-type files do not allow binary transfers, but only text files. Thereafter, they are added to the head together with the text web document to be reconstructed into a multimedia message in a multi-part format (step S111). The structure of the MMS message is described in the Multimedia Messaging Service Encapsulation Protocol, Approved Version 1.1? Documented as OMA-WAP-MMS-ENC-V1_1-20040715-A. This is described in detail in 15 Jul 2004. This file consists of a message header part and a message body part containing a presentation, image, text and audio file. The header includes the MMS message type, transaction ID, version and send date, sender, receiver, reference recipient, subject, priority information, and rate information.

At this time, receiver identification information such as a phone number and caller information are added (step S111). The generated multimedia message is transmitted to the MMS server 20 and transmitted to the receiver terminal set through the mobile communication network (step S113).

In the case of broadcast transmission, the reconstructed message is repeatedly transmitted to a plurality of receiving terminals. In addition, when the receiver has the adaptation information which is a different field, the steps S111 and S113 are repeated, and a series of broadcast messages generated by updating the receiver field and the adaptation information fields are sequentially sent.

As described in detail above, according to the present invention, multimedia messages that are not familiar to designers are generated in a web document creation tool, which is a more familiar tool, and then converted into a multimedia message format for transmission. Can be.

The present invention has been described with reference to the embodiments described with reference to the accompanying drawings, but is not limited thereto, and should be interpreted by the claims intended to cover various modifications apparently derived therefrom.
