1 is a flowchart illustrating a text chatting service providing method according to embodiments of the present invention. FIG. 2 is a diagram illustrating an exemplary text chat window of a mobile communication terminal provided with the text chat service described with reference to FIG. 1.

Referring to FIG. 1, a long message service (LMS) message is transmitted or received through a mobile communication terminal (S10).

Here, LMS message is a concept in contrast to SMS (Short Message Service) message, LTS (Long Text Service) that can only send and receive text, MMS (Multimedia Message Service) that can send and receive text / picture / music / video, etc. It may include. In addition, the MMS message may be made of Hyper Text Makeup Language (HTML) or Synchronized Multimedia Integration Language (SMIL). If it is made of SMIL, it can send and receive synced video, but if it is made of HTML, it is difficult to send and receive synced video.

Subsequently, the text is extracted from the LMS message (S60).

As described above, the LMS message may be implemented in various ways, and the method of extracting text may be slightly different for each method. An example of a method of extracting text will be described with reference to FIGS. 3 to 9.

Next, the extracted text is displayed in the text chat window (S70).

2, an exemplary text chat window of a mobile communication terminal provided with a text chat service includes a chat title display area 110, a chat message display area 120, a chat message input area 130, and a menu. Region 140 may be included.

The chat title display area 110 is an area for displaying the title of the current chat. The chat title display area 110 may display a separate chat title or may display a phone number or name of the counterpart. The chat message display area 120 is an area for displaying a message currently transmitted and received as a chat message. That is, an area in which messages received from the other party and messages sent by the user are arranged over time. The chat message input area 130 is an area where a chat message to be transmitted by a user is displayed. The menu area 140 is an area for displaying key functions necessary for creation and transmission. The chat message display area 120 and the chat message input area 130 may be moved up and down by scrolling.

For example, if the user is 01030101873 and the counterpart 01030101878 is shown in FIG. 2, the user sends "Where? I'm eating" and the counterpart replies "hahahaha. I'm playing." Here, when the other party sends an LMS message including a picture and music (for example, an LMS message made of SMIL), only text is extracted from the LMS message and only the text is displayed in the text chat window as shown in FIG. 2. That is, pictures and music that are difficult to be displayed in the text chat window are excluded, and only displayable text is displayed in the text chat window.

In the method of providing a text chat service according to the embodiments of the present invention, since the LMS message can be displayed in the text chat window, even if the LMS message is received during the text chat, it is possible to check the message without stopping the text chat. Therefore, the user can conveniently use the chat chatting service.

3 is a block diagram illustrating a text chat service providing method according to an embodiment of the present invention. 3 is a diagram illustrating in detail a method of providing a text chat service, in particular when an LMS message is received. 4 to 6 are diagrams for explaining an operation of extracting text from the LTS message of FIG. 3 (S62), and FIGS. 7 to 9 illustrate an operation of extracting text from an MMS message of FIG. 3 (S64). Figures for. 8A and 8B are continuous views (ie, the program of FIG. 8A and the program of FIG. 8B are connected).

First, referring to FIG. 3, a message is received (S11).

Next, it is examined whether there is a text chat currently in progress (S20). If there is no text chat currently in progress, it notifies that the message has been received (S32). There may be various ways of notifying that the message has been received, for example, displaying an icon indicating that the message has been received, or making a sound such as an alarm bell.

If the text chat is in progress, it is checked whether the return phone number of the message and the chat phone number in the text chat are the same (S30). If the reply phone number and the chat phone number is not the same, it informs that the message has been received (S32).

If the return phone number and the chat phone number are the same, it is checked whether the message is an SMS message or an LMS message (S40).

If the SMS message, the SMS message is displayed in the text chat window (S42).

In case of the LMS message, the type of the LMS message is examined (S50). In the case of the LTS message, the text is extracted in the same manner as described in FIGS. 4 to 6 (S62). In the case of the MMS message, the text is extracted in the same manner as described in FIGS. 7 to 9 (S64).

The extracted text is displayed in the text chat window (S70).

On the other hand, in Figure 3, the progress of the review of the text chat in progress (S20), the reply phone number and the chat phone number is the same (S30), LMS message whether the review (S40) in order, but the order of the three considerations May change or change. For example, after reviewing whether there is an ongoing text chat (S20), it may be checked whether it is an LMS message (S40), and may be reviewed (S30) whether the reply phone number and the chat phone number are the same.

Hereinafter, a method of extracting text from an LTS message will be described with reference to FIGS. 4 to 6.

Referring to FIG. 4, first, in case of an LTS message, what the Content-Type is is examined (S81).

If the LTS message has Content-Type of text / plain, the text between CRLF and CRLF following Content-Length is extracted in the LTS message (S82).

For example, referring to FIG. 5, in the case of Content-Type: text / plain (a1), CRLF () following Content-Length: 116 (a2)

) And CRLF (

) (I.e. "My day is a lot of fun, apart from everyday things. People who live with the dreams of the future will be happy"). Where CRLF (

Is a character that means line breaks.

If the Content-Type is an LTS message having text / html, the text between <body> and </ body> following Content-Length is extracted in the LTS message (S83).

For example, referring to FIG. 6, in the case of Content-Type: text / html (b1), the text (b3) between <body> and </ body> following Content-Length: 166 (b2) (that is, Extract "If the Content-Type is text / html, test if the color tag is supported.").

Meanwhile, referring to b3, <body Bgcolor = Blue> <font color = 'red'> may be removed. That is, in the text chat window, the font color of the text ("Test whether the color tag is supported when the Content-Type is text / html" should be sent like this ") is not red. The font used in the text chat window is not red. It may be displayed in color.

Next, it is checked whether the extracted text size is equal to or larger than a predetermined size (for example, 2048 bytes) (S84).

If the extracted text size is larger than the predetermined size, the text is left only up to the predetermined size and the rest is removed (S85). The predetermined size may vary depending on the design. In addition, this step is an optional step, and if there is no such step, the text may be displayed in the text chat window without any size limitation.

Hereinafter, a method of extracting text from an MMS message will be described with reference to FIGS. 7 to 9.

Referring to FIG. 7, in case of an MMS message, it is checked whether it is made of SMIL (S91).

If it is made of SMIL, it finds the specified text source between <body> and </ body> (S92). The content corresponding to the text source is found (S93). If the Content-Type of the content is text / html, the text between <body> and </ body> in the content is extracted (S94).

For example, referring to FIGS. 8A and 8B, since it is written as m_Application: LMS / SMIL (c1), it can be seen that it is made of SMIL. The statement that specifies the text source between <body> and </ body> is <text region = "text" src = "Message.htm"> (c2). In other words, the text source is Message.htm. Looking at the Content-ID: <Message.htm> (c3), the content corresponding to the text source can be found, and the Content-Type: text / html (c4) shows the type of the content. You will extract the text between the <body> and </ body> ("KTF SMIL type MMS message service.

If it is not made of SMIL (eg, made of HTML), the text between <body> and </ body> is extracted (S95).

For example, referring to FIG. 9, it can be seen that it is an MMS message because m_Application: LMS / MMS (d1) is written. In this case, you would extract the text between the <body> and </ body> ("You're sea fishing in Daecheon Port with people.

On the other hand, when extracting the content between the <body> and </ body> (S94, S95), it is possible to delete all tags except tags indicating the line break character and special characters (S96). The tag deletion step S96 is optional, and the tag that can be displayed in the text chat window may not be deleted.

Next, it is checked whether the extracted text size is equal to or larger than a predetermined size (for example, 2048 bytes) (S97).

If the extracted text size is larger than the predetermined size, the text is left only up to the predetermined size and the rest is removed (S98). The predetermined size may vary depending on the design. In addition, this step is an optional step, and if there is no such step, the text may be displayed in the text chat window without any size limitation.
