Hereinafter, the present invention will be described with reference to the accompanying drawings.

1 is a block diagram illustrating an internal structure of a mobile communication terminal according to an embodiment of the present invention. SMS (Short Message Service) section, a text chat mode (3) for implementing text chat via the short message (2) section, and a memory section (4) in a mobile communication terminal for storing texts to be transmitted and received. ) And a radio frequency unit 5 associated with text transmission and reception.

The text chat mode (3) is related to the transmission and reception of a short message in the mobile communication terminal through the short message (2), when the user inputs only the text, the short message completed by automatically setting the short message related data for text transmission The data is transmitted as text chat data having a message structure, and the transmitted text data and the received text data are displayed on the liquid crystal display of the mobile communication terminal and stored in the memory unit 4.

The text chat data transmitted / received through such a configuration is composed of a text data structure as shown in FIG. -SERVICE) A specific value defined as a value indicating that the text chat data is input to the area 20 is used as the text chat message identifier.

By using the above configuration, the present invention provides a first step of transmitting a text chat request signal to a third party by selecting a text chat mode by a user of a mobile communication terminal capable of switching a text chat mode in a call mode or an idle mode; A second step of determining whether a third party responds to the text chat request signal; A third step of executing a text chat between the user and a third party or returning to a previous call mode or an idle mode according to whether the response is determined; A fourth step of determining whether a text chat cancellation signal is generated by the user or a third party in the text chat process performed through the third step; And a fifth step of terminating the text chat mode when the text chat cancel signal is determined through the fourth step, and continuing to maintain the text chat mode if the text chat cancel signal is not determined.

The operation of the present invention made as described above will be described according to the state of the call mode or the idle mode where the mobile communication terminal user is talking to the third party.

First, FIG. 3 illustrates a call mode in which a call link is established between a user's mobile communication terminal (hereinafter referred to as a first terminal) and a third party's mobile communication terminal (hereinafter referred to as a second terminal) to establish a call between the user and a third party. The operation flow of the present invention in more detail is shown.

4 illustrates a liquid crystal display of a first terminal indicating a call mode state of a first terminal. When a user of the first terminal selects a chat button 401 in the call mode, a signal corresponding to a text chat mode is generated. The character chat mode signal is detected to determine whether the character chat mode is selected (S1).

If the text chat mode is not selected in the step S1, return to the previous call mode state, and if the text chat mode is selected, the text chat mode is executed in the previous call mode state and the first terminal user is sent to the second terminal user. The text chat request signal is transmitted together with the text message indicating the text chat connection (S2).

When the text message and the text chat request signal are received at the second terminal, the second terminal user checks the text message and determines whether to respond to the text chat request of the received first terminal user (S3).

In step S3, when the second terminal user responds to the text chat request, the text chatting mode of the second terminal is executed, and the text chatting mode between the first terminal user and the second terminal user is connected to the first terminal user. Input the character to be transmitted to the second terminal user.

Alternatively, if the second terminal user does not respond to the text chat request message in step S3, the text chat mode of the first terminal is terminated (S4).

In step S4, the first terminal adds a signal requesting an acknowledgment signal when the text message is transmitted from the first terminal, and receives the acknowledgment signal transmitted from the second terminal after the text message is confirmed. The text message transmitted by the first terminal user is displayed on the liquid crystal display of the first terminal, and the text message is stored in the memory of the first terminal (S5).

After the first terminal user transmits the text message through the step S5, it is determined whether the response message transmitted from the second terminal user is received (S6).

When the answer message is received in step S6, the acknowledgment signal is transmitted to the second terminal as the source, and the received answer message is displayed on the liquid crystal display of the first terminal and the answer message is stored in the memory unit (S7).

The text message transmitted and received through the above process is displayed on the liquid crystal display of the mobile communication terminal as shown in FIG. 5 and stored in the memory unit of the mobile communication terminal, so that the user can conveniently check the content of the text message previously transmitted and received.

After the response message is not received in step S6 or after performing step S7, it is determined whether the text chat mode is canceled by detecting the text chat mode signal generated by the selection of the interrupt button 501 of the first terminal user. (S8).

If the character chat mode cancellation signal is not detected in step S8, the character chat mode is maintained and the character chat mode is terminated when the character chat mode cancellation signal is detected.

Since the text chat mode process is performed while the first terminal and the second terminal are in a call state, the first terminal user and the second terminal user may chat with the earphone or speakerphone while text chatting or stop talking for a while. It is.

Since the call is not terminated even if the text chat mode is terminated through the step S8, the voice call can be continued even after the text chat ends.

Secondly, the operation flow according to the present invention in the idle mode in which the first terminal is not used will be described. In the idle mode, the present invention can be implemented through a short service or a data calling method.

The implementation of the short message service in the idle mode is such that when the first terminal user calls the second terminal user for text chatting, the text chatting mode can be automatically executed when the second terminal responds to the text chatting request signal. Transmit call signal by setting designated bit of DATA BURST.

In response to the transmitted call signal, a text chat mode is automatically executed to connect a text chat mode of a first terminal and a second terminal period, and then a text chat process is performed, such as a text chat process in the call mode.

The call signal is similar to a general voice call, so that a voice call may be performed in a text chat mode of the first terminal and the second terminal.

When the user of the first terminal wants to call the second terminal, the implementation of the character call in the idle mode calls the data by setting a specific bit of the access channel and responds to the data call in the second terminal. Lets text chat mode run automatically.

The text chat is transmitted / received through a set access channel and is performed in a data packet exchange scheme.

In addition to the implementation in the call mode or the idle mode, the present invention transmits a DTMF (Dual Tone Multi Frequency) signal generated by the user pressing each keyboard on the keypad of the mobile communication terminal in a voice call state of the mobile communication terminal. Combining the received DTMF signal in the text and converts it to the text display on the LCD of the receiving mobile communication terminal so that the user of the mobile terminal can chat even in the voice call state.

In addition, in the voice call state, the data burst message of the access channel is used to execute the text chat mode of the first terminal and the second terminal period by using the second access channel of the MULTOplex Option 1 or 2 in the voice call state. Character chat mode can be implemented.

As described above, the present invention can express the contents of the call through text chat even if the user cannot move to a place where noise must be maintained or a noisy place during the call and cannot continue the call with the other party. Since the call can be parallel, information such as address, phone number, account number, etc. can be clearly transmitted by text, and the disability, which is impossible for voice call, can be easily communicated with the general public.
