FIG. 2 is a flowchart illustrating a procedure for performing a call connection in an originating portable terminal according to a preferred embodiment of the present invention.

Referring to FIG. 2, the portable terminal first establishes a call connection with a receiving terminal in step 201, and then proceeds to step 203 to transmit a voice signal or a text signal. This means that a user of the portable terminal communicates with a user of a receiving terminal via a voice or transmits a text message. The portable terminal uses a voice signal with the receiving terminal according to a preferred embodiment of the present invention, The call connection can be maintained using the character signal during the call connection. On the other hand, the portable terminal can maintain the call connection by using the voice signal during the call connection using the character signal. This means that a voice signal of a user using the portable terminal is converted into a character signal or a character signal is converted into a voice signal to perform a call connection.

Thereafter, the portable terminal proceeds to step 205 and confirms whether a voice signal is received from the counterpart terminal.

If it is determined in step 205 that a voice signal is received from the partner terminal, the portable terminal proceeds to step 207 and outputs the voice signal received from the receiving terminal to the speaker.

If it is determined in step 205 that the text signal is received from the counterpart terminal, the portable terminal proceeds to step 211 and performs a text to speech (TTS) function for converting the text signal to a voice signal. And converts the received character signal into a voice signal.

Thereafter, the portable terminal proceeds to step 215 and outputs the changed voice signal to the speaker.

The portable terminal outputting the voice signal to the speaker as in steps 207 and 215 proceeds to step 209 to check whether the call with the other terminal is terminated.

If it is determined in step 209 that the communication with the counterpart terminal is not terminated, the portable terminal performs the procedure of step 201.

On the other hand, if it is confirmed in step 209 that the communication with the partner terminal is completed, the portable terminal ends the algorithm.

Then, the portable terminal proceeds to step 309, To the display unit. At this time, the portable terminal can perform the above-described steps by executing a function of changing a voice signal to a text signal (STTspeech to text).

If it is determined in step 305 that the voice signal is not received from the partner terminal, the portable terminal proceeds to step 319 and determines whether the voice signal is received.

If it is determined in step 319 that the character signal is received from the partner terminal, the portable terminal proceeds to step 321 and outputs the received character signal to the display unit.

The portable terminal outputs the rubbing signal to the display unit as described above. In step 311, the portable terminal confirms whether the voice signal is to be transmitted to the calling terminal.

In addition, if the mobile terminal does not receive a character signal or a voice signal in steps 305 and 319, the portable terminal proceeds to step 311 and checks whether there is a user signal to be transmitted to the calling terminal.

That is, if there is a signal to be transmitted to the calling terminal, the portable terminal determines in step 311 whether to transmit the voice signal to the calling terminal.

If it is determined in step 311 that the voice signal is to be transmitted to the calling terminal, the portable terminal proceeds to step 313 and outputs a character input screen to receive a text by a user to generate a text signal.

In step 315, the portable terminal converts the character signal generated using the received text into a voice signal and transmits the voice signal to the calling terminal.

At this time, the portable terminal converts the received voice signal into a character signal so as not to provide inconvenience to a nearby user in a speakerphone mode, and can receive the voice signal in the opposite-party calling terminal. As described above, the portable terminal converts the character signal into a voice signal in the portable terminal itself and provides the voice signal to the calling terminal, or provides a character signal to the calling terminal so that the calling terminal itself converts the voice signal into the voice signal using the TTS function .

If it is determined in step 311 that the character signal is to be transmitted to the calling terminal, the portable terminal proceeds to step 323 and outputs a character input screen to generate a character signal by inputting text by the user, And transmits the generated character signal to the calling terminal.

In step 317, the portable terminal that has transmitted the text signal to the calling terminal determines whether the call with the calling terminal ends.

If it is determined in step 317 that the call with the calling terminal is not terminated, the portable terminal proceeds to step 305 and maintains a call with the calling terminal.

On the other hand, if it is confirmed in step 317 that the call with the calling terminal is ended, the portable terminal ends the present algorithm.

In addition, the portable terminal can detect the input of the user and enter the text communication mode. However, the portable terminal can automatically enter the text communication mode according to the location, time, calling number, You can enter. This will be described in detail in Figs. 4 to 6 below.

Here, the character phone call profile is information in which a condition for entry into the character phone mode is set, and the portable terminal sets a condition suitable for the character phone call profile corresponding to the position, time, calling number, So as to enter the text communication mode.

In order to enter the text communication mode with the location information according to the preferred embodiment of the present invention, the portable terminal first checks the location information of the portable terminal in step 401 and then proceeds to step 403 to load the stored text phone call profile do.

In step 405, the portable terminal determines whether the portable terminal is located in an area corresponding to the location information of the textual communication profile. For example, the portable terminal confirms whether the user is located in an area such as a church, an office, a conference room, or the like where the user can not make a call to the speakerphone mode.

If it is determined in step 405 that the portable terminal is not located in the area corresponding to the location information of the textual call profile, the portable terminal repeats the procedure of step 401.

If it is determined in step 405 that the portable terminal is located in the area corresponding to the location information of the text communication profile, the portable terminal proceeds to step 407 to enter the text communication mode. Accordingly, even if the portable terminal operates in the speakerphone mode, the contents corresponding to the voice signal of the user of the other party are converted into a character signal without being output to the speaker, and are output to the display unit.

Thereafter, the portable terminal terminates the present algorithm.

5 is a flowchart illustrating a process of entering a text communication mode in a portable terminal according to another preferred embodiment of the present invention.

Referring to FIG. 5, in step 501, the portable terminal confirms whether a call connection request is received from a calling terminal in order to enter a text communication mode as calling information according to another preferred embodiment of the present invention.

If the mobile terminal does not receive the call connection request in step 501, the mobile terminal proceeds to step 511 and performs a corresponding function (e.g., standby mode).

If it is determined in step 501 that the call connection request is received, the mobile terminal proceeds to step 503 and checks the caller information attempting to establish a call connection. Here, the sender information may be a sender's name, a sender's phone number, a sender's nickname, and the like.

Then, the portable terminal proceeds to step 505 and loads the stored text-to-speech profile, and then confirms the calling mode per caller.

In step 507, the portable terminal determines whether a call connection has been received from the caller corresponding to the caller information of the character call profile.

If the call connection is received from the caller who does not correspond to the caller information of the text communication profile in step 507, the portable terminal repeats the procedure of step 501.

On the other hand, if the call connection is received from the caller corresponding to the caller information of the text communication profile in step 507, the portable terminal proceeds to step 509 to enter the text communication mode. Accordingly, even if the portable terminal operates in the speakerphone mode, the contents corresponding to the voice signal of the user of the other party are converted into a character signal without being output to the speaker, and are output to the display unit.

Thereafter, the portable terminal terminates the present algorithm.

6 is a flowchart illustrating a process of entering a text communication mode in a portable terminal according to another preferred embodiment of the present invention.

Referring to FIG. 6, in order to enter a text communication mode according to another preferred embodiment of the present invention, the portable terminal operates a sensor for grasping an external environment in step 601, and then, in step 603 And acquires external environment information using the operated sensor. Here, the external environment may be ambient brightness, ambient noise, or the like.

Then, the portable terminal proceeds to step 605 and acquires the internal environmental condition of the portable terminal. Here, the internal environmental condition of the portable terminal is information for grasping a user's call pattern, such as location information of the portable terminal, the current time, the frequency of call origination, the mode of the manner mode, and the like. For example, the portable terminal can determine that the user can not make a call to the speakerphone mode (e.g., determine that the conference is in session) when the frequency of calling is low at a specific time using the internal environmental condition.

In step 607, the portable terminal loads the text communication profile to confirm whether the condition satisfying the text communication profile is obtained.

If it is determined in step 607 that the condition satisfying the text communication profile is not obtained, the portable terminal repeats the procedure of step 601. [

On the other hand, if the condition satisfying the text communication profile is obtained in step 607, the portable terminal proceeds to step 609 so as to enter the text communication mode. Accordingly, even if the portable terminal operates in the speakerphone mode, the contents corresponding to the voice signal of the user of the other party are converted into a character signal without being output to the speaker, and are output to the display unit.

Thereafter, the portable terminal terminates the present algorithm.

7 is a diagram illustrating a process of performing a text communication mode in a portable terminal according to a preferred embodiment of the present invention.
