Description

How to enter special characters in mobile terminal {METHOD FOR INSERTING SPECIAL CHARACTER IN MOBILE PHONE}

The present invention relates to a mobile communication terminal, and more particularly, to a text input method in a mobile communication terminal.

Typically, a text service is a service that enables users of mobile communication terminals to send and receive short sentences of about 40 characters without additional equipment, and is also called a short message service (SMS). As the spread of mobile communication terminals spreads rapidly, the population of short message service users is increasing rapidly, and unlike e-mail, contents can be delivered at almost the same time as when they are sent. Basically, a function of transmitting a reply number and a message between mobile communication terminals is provided, and it is possible to know weather forecasts, news, stock information, etc., and the user can directly search for various information and select only necessary information. In addition, it is possible to send and receive e-mail through the Internet / PC communication, etc., and can provide various information retrieval services necessary for daily life. In particular, since information is provided interactively for the convenience of the user, it is easy for anyone to use, and thus the use of middle-aged and middle-aged people who are outside the use of information is increasing.

The short message service is performed by receiving and sending a short message in a text form by a mobile communication terminal user in a mobile communication system including a base station, a mobile switching center, a home location register, a short message center, and the like. Such a short message may be made between mobile communication terminals, or may be made between an information server of an operator providing various information and a personal mobile communication terminal.

Such a short message is useful as a method of transmitting information when the user cannot make a voice call or when the power is turned off. In addition, the new generations have a unique fun by making various types of text emoticons according to their unique personalities and exchanging them with friends through a short message service.

As mentioned above, user needs are becoming more diverse and detailed than ever before. However, only one letter shape is used to display the content of a message when receiving a short message.

As described above, the conventional mobile communication terminal allows a user to have only one letter shape and '!,?, #,...' The short message was written using only special symbols. As a result, users are feeling uncomfortable and sick with the fixed letter shape of the mobile communication terminal. Also, for example, when trying to express an onomatopoeic, which is a fascinating sound, in a letter itself, a letter size such as the same letter font is not expressed. Therefore, in order to satisfy various needs of the user, a method of adding a desired font shape and font size by the user is required.

Accordingly, the present invention allows a user to create a short message using a special character expressing emotion feelings in various character sizes and shapes in a mobile phone terminal to create a short message including the special characters expressing the feeling and send the short message composed. Provide a way to.

In order to achieve the above object, the present invention provides a special character input method in a mobile communication terminal storing at least one or more special characters in a memory unit, and has various shapes and sizes in response to a special character download request from a user. Accessing a server that provides a special character, downloading the special character selected by the user, and storing the special character in the memory unit; and when the short message is requested, the special character stored in the memory unit when the special character input request is received from the user. Displaying a list of characters, selecting one from the user from the list, reading and displaying the selected special character from a memory unit, and completing the short message, and writing a short message including the special character. Contains code value to inform It characterized in that it comprises the step of transmitting the short message.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the same elements in the figures are represented by the same numerals wherever possible. In addition, detailed descriptions of well-known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.

Hereinafter, an internal configuration diagram of a mobile communication terminal according to an embodiment of the present invention will be described with reference to FIG. 1. Referring to FIG. 1, the controller 100 controls the overall operation of the mobile communication terminal and performs a control operation for editing a call, a phone number, and transmitting / receiving mail according to a user's request. In addition, the control unit 100 downloads the special characters in the form of pictures expressing the feelings of the person to send to the text according to an embodiment of the present invention and stores them in the memory unit 130, and special from the user when creating a short message If there is a request for character input, the special character list is displayed through the display unit 110. If any one of the displayed special character list is selected by the user, the control unit 100 extracts the corresponding special character and data information thereof from the memory unit 130 in response to the selection and displays it on the short message creation screen. The data information for the special character is transmitted along with the short message when the short message is transmitted.

Here, special characters have a unique identification number for each special character. For example, if the unique identification number ranges from 0x1000 to 0x1100, each special character is the same as ASCII characters when downloading special characters or when sending short messages containing special characters. Must have a unique identification number and textual information about the character. In addition, the reason why the special character should have text information about the character in addition to the unique identification number corresponds to the unique identification number when the receiving mobile terminal user who has not previously downloaded the special character receives a short message containing the special character. There is no special character to prevent characters from appearing broken on the screen, and to make the original characters appear instead.

In addition, the control unit 100 transmits by setting a code value indicating that a special character is included in an arbitrary reserved field in the short message format to be transmitted in order to indicate that the short message includes a special character. do.

In other words, according to an embodiment of the present invention, the short message format transmitted to the receiving mobile terminal may include a field for storing a specific code indicating that a special character expressing a feeling is included in the short message to be transmitted. Such a field may be allocated using a part of a field such as a spare field among various fields of a conventional short message structure. Alternatively, a field for storing a specific code indicating that a special character expressing a feeling is included in the fields of a header of a general short message may be additionally defined and used.

On the other hand, the control unit 100 in the receiving side mobile communication terminal analyzes the received short message format to determine whether the data information for the special character is included, and if it is determined that the special text is included in the received short message is special The memory unit 130 searches for a corresponding special character according to the data information about the character. If there is a corresponding special character as a result of the search, the control unit 100 displays the content of the short message together with the special character through the display unit 110. On the contrary, if there is no corresponding special character as a result of the search, the control unit 100 displays a message asking whether to download the special character through the display unit 110, and in response to the download request from the user, displays the special character as the special character. The special character is downloaded from the server providing the download service, and the short message including the special character is displayed through the display unit 110. On the other hand, if a user does not request a download in response to a message asking whether to download a special character, the control unit 100 converts the special character into a text character according to data information on the special character, and includes the converted text character. The short message is displayed through the display unit 110. As such, the controller 100 performs a corresponding function according to data information analysis on the special character in the received short message.

The display unit 110 outputs state information of the mobile communication terminal and various display data according to a use mode under the control of the controller 100. In addition, when a short message including a special character according to an embodiment of the present invention is received, it is displayed as an image under the control of the controller 100. The key input unit 120 includes various keys including numeric keys to provide the control unit 100 with key input data input by the user. In addition, the memory unit 130 connected to the control unit 100 includes a read only memory (ROM), a random access memory (RAM), and a voice for storing a plurality of programs and information necessary for controlling the operation of the mobile communication terminal. Memory, etc. In addition, the memory unit 130 is downloaded under the control of the control unit 100, for example, a memory area for storing the downloaded ringtone, etc. is separately allocated according to an embodiment of the present invention. Stores special characters and data information about them. As such, the memory unit 130 requests, downloads, and stores the special character data expressing the feelings of the user to the service providing server under the control of the control unit 100, and stores them according to the user's request. It has a built-in program with the ability to select and use special characters.

In addition, the RF module 150 transmits / receives an RF signal with a base station through an antenna ANT. The RF module 150 converts the received RF signal into an IF (Intermediate Frequency) signal and outputs the signal to the baseband processor 140. 140 converts the IF signal input from the RF signal to transmit. The baseband processor 140 is a baseband analog ASIC (BAA) that provides an interface between the controller 100 and the RF module 150. The baseband processor 140 converts a baseband digital signal applied from the controller 100 into an analog IF signal. Applied to the RF module 150, and converts the analog IF signal applied from the RF module 150 to a digital signal of the baseband and applied to the control unit 100. The voiceband signal processor 160 connected to the controller 100 is connected to the microphone MIC and the speaker SPK, and outputs the voice signal received from the microphone MIC to the controller 100. The voice data input from the controller 100 is converted into an audible sound through the speaker SPK and output.

Hereinafter, referring to FIG. 2, which is a control flowchart for explaining a process of downloading a special character from a server according to an exemplary embodiment of the present invention. Referring to FIG. 2, first, in step 200, the controller 100 determines whether there is a key input corresponding to a request for adding a special character from a user. Accordingly, the control unit 100 proceeds to step 210 to display the initial screen of the special character download service through the display unit 110. Here, the special character download service is a service provided through a server which is a communication service provider supporting a mobile internet service or a general wireless internet service. In addition, the special character provided by the special character download service may be a special character designed and provided by a special character service company or a special character designed directly by a user using a special character production tool provided by the special character service company.

Then, the controller 100 proceeds to step 220 and selects the special character data desired by the user to determine whether there is a key input for requesting the download of the selected special character data through the wireless Internet. In response to the download request, the controller 100 proceeds to step 230 to download the selected special character data. Then, the controller 100 determines whether the download of the special character data requested by the user in step 240 is completed and the special character data is received. If the special character data is received as a result of the determination, the control unit 100 proceeds to step 250 and the special character data, ie, special character data, is stored in the memory area allocated for storing the special character of the memory unit 130. Stores the unique identification number of a character and textual information about that character.

Next, referring to FIG. 3, which is a control flowchart for explaining a process of creating a short message using the downloaded special character according to the first embodiment of the present invention. A description with reference to FIG. 3 is as follows.

First, when the short message is created by the user in the short message writing mode, the control unit 100 determines whether there is a corresponding soft key input corresponding to a special character input request from the user in step 300. For example, as illustrated in FIG. 5A, items related to a text menu for inputting a short message are displayed at the bottom of the screen. In particular, a menu showing a special symbol such as an exclamation point shown at the bottom right of the screen is used by a user when inputting a special character expressing an emotional feeling according to an embodiment of the present invention in addition to a general sentence input when writing a short message. Menu.

In other words, according to an embodiment of the present invention, when inputting a special character in addition to a menu such as "a", "A", "a", "special", etc., which corresponds to a character mode for creating a short message, in general, when creating a short message. for "!" Add a menu called here "!" Is a menu for inputting special characters expressing emotions and feelings. If there is no menu selection corresponding to a special character input request by the user among the menus, the control unit 100 proceeds to step 310 to perform a corresponding function according to a general short message writing. In contrast, these menus correspond to special character input needs by the user through the "!" If the menu is selected, the control unit 100 proceeds to step 320 to load the special character list and displays it through the display unit 110 in the same manner as the conventional special symbol display method. Then, the control unit 100 proceeds to step 330 to determine whether there is any selected special character from the user among the displayed special character list. Accordingly, when there is a special character selected by the user, the control unit 100 proceeds to step 340 to read the selected special character from the memory unit 130, and proceeds to step 350 to display the read special character. Display through 110.

When the above-described in detail by way of example, in the embodiment of the present invention to express a variety of emotional feelings, such as a feeling of lovable feelings, such as sobbing in the letters themselves, various characters for each letter without varying the same font size Provides different sizes and shapes. For example, when expressing the feeling of the onomatopoeia, the sound of "ang ~ ang ~ ang ~", in the letter itself, it may be expressed by different letter sizes and letter shapes as shown in FIG. 5A. Here, a description will be given with reference to FIG. 5A, which is an exemplary diagram of a screen displaying a short message representing a special character according to a first embodiment of the present invention. As shown in FIG. 5A, a special character of "ang" of three different sizes and shapes is displayed on the screen.

First, the letter "ang" corresponding to the first special character assigns the size and shape of the letter to a unique identification number, for example, 0x1101, and the letter "ang ~" is a unique identification number for the letter. It also contains information indicating that the plain text "ang" is a letter. And, the second special character "ang ~" is a medium sized letter, for example, has a unique identification number, such as 0x1102, with information indicating that the plain text "ang" letters, and to show the feeling of patience For this reason, it is expressed as a graphic letter rather than a specific font. Similarly, the third special character "ang" displayed on the screen is the smallest sized letter, for example, with a unique identification number of 0x1103, and the shape of the letter expresses a feeling of patience, and the plain text "ang" It also contains information to indicate that it is.

As described above, a user may create a short message in a sentence by including a special character expressing a desired feeling through the above-described method. Determine whether the short message input by the user is completed. As a result of the determination, when the input of the short message is completed, the control unit 100 proceeds to step 370 to determine whether there is a request for transmitting a short message including a special character from the user. If there is such a request, the control unit 100 proceeds to step 380 and includes a code value indicating that a special character is included in the short message in the same field as any spare field among several fields in the short message format. Transmit to mobile communication terminal.

Meanwhile, referring to FIG. 4, which is a control flowchart for explaining a process of creating a short message using the downloaded special character according to the second embodiment of the present invention. The following description will be made with reference to FIG. 4.

First, in the short message writing mode, the control unit 100 corresponds to a text code value of a character input to the memory unit 130 whenever a character is input by the user through the key input unit 120 in step 400. Search for special characters. The special character search corresponding to the input character may be performed by comparing text information of a unique identification number which is data information on the special character and text information indicating the original character of the special character.

In order to explain such a special character insertion process with reference to FIG. 5B. 5B is a diagram illustrating a screen displaying a short message representing a special character according to a second embodiment of the present invention. As shown in FIG. 5B, when one character of "ang" is input from the user, the controller 100 recognizes text information, such as ASCII code value, of the input "ang" character of the memory unit 130. Search the memory area that stores the character. The controller 100 proceeds to step 410 to search for a special character having text information that matches the text information for the "ang" character in the corresponding memory area and displays a list of the corresponding special characters in FIG. 5B. Display as shown. The controller 100 proceeds to step 420 to determine whether there is a special character selected by the user from the list of displayed special characters.

Hereinafter, steps (430) to (470) of the control flow diagram for explaining a process of creating a short message using the downloaded special characters according to the second embodiment of the present invention are the first embodiment of the present invention of FIG. Similar to the steps 340 to 380 of the control flow diagram for explaining a process of creating a short message using the downloaded special character according to the detailed description thereof will be omitted. However, if it is determined in step 420 that there is no special character selected by the user in the control flow chart for explaining a process of creating a short message using the downloaded special character according to the second embodiment of the present invention, the controller 100 ) Differs from the first embodiment in that it proceeds to step 450 to determine completion of the short message input.

Next, when the receiving side mobile communication terminal receives the short message containing the special character created by the above-described method, a process of displaying the received short message will be described. To this end, a control flow diagram of a receiving mobile communication terminal when receiving a short message including a special character according to an exemplary embodiment of the present invention will be described with reference to FIG. 6.

First, the control unit 100 of the receiving mobile terminal in the standby state receives the short message from the transmitting mobile terminal in step 600, and proceeds to step 605 in a predetermined field in the received short message format. It is determined whether a code value indicating that a special character is included is set. Through this, if it is determined that the special character is not included in the received short message, the control unit 100 proceeds to step 610 to perform a corresponding function according to normal short message processing. In contrast, if it is determined that the received short message includes the special character, the controller 100 proceeds to step 615 to analyze the data information on the special character included in the short message according to the analyzed information. Search whether the special character is in the memory unit 130.

If there is no corresponding special character as a result of the search, the control unit 100 proceeds to step 620 and displays a message asking whether to download the special character through a special character download service in order to display the special character in the received short message. It is displayed through the display unit 110 in the form of a pop-up window. When the controller 100 receives a request such as a key input for downloading the corresponding special character from the user in step 625, the controller 100 connects to the server providing various special characters through the wireless Internet. Handles the function of downloading special characters. On the other hand, the control unit 100 proceeds to step 635 when the special character is present in the search result memory unit 130 of the data information analysis of the special character included in the short message in step 615 to select the special character. The short message content including the special character is read from the memory unit 130 and displayed on the display unit 110.

On the contrary, when the control unit 100 receives a selection not to download the special character from the user in step 625, the control unit 100 proceeds to step 640, where the data information about the special character in the short message, that is, the unique identification number and the original. Analyze textual information for the representation of characters. According to the analysis, the control unit 100 proceeds to step 645 to convert the special characters included in the short message into text characters. Then, the control unit 100 proceeds to step 650 to display the content of the short message including the converted text characters through the display unit 110.

For example, when a short message is transmitted to a receiving mobile terminal by inputting a special character expressing an emotional feeling into the short message in the transmitting mobile terminal, the receiving mobile terminal corresponds to the short message. When the special character is in the memory unit 130, a short message including the special character is displayed as shown in FIG. 5A. On the other hand, when the user selects not to download the special character when the special character is not present in the memory unit 130 in the receiving mobile terminal, the special character included in the received short message is the original text. It is converted into text and displayed as shown in FIG.

As described above, if there is no corresponding special character among the special characters included in the short message received by the receiving mobile communication terminal and the special characters of the memory unit 130 that have previously downloaded and stored the special characters, the user is optional. Select whether to download the special character. In particular, when the user of the receiving mobile terminal does not download the corresponding special character, the special character included in the short message may be displayed as the text is broken on the screen because there is no special character corresponding to the unique identification number. For this reason, when a receiving mobile terminal user who has not downloaded special characters in advance receives a short message containing the special characters, there is no special character corresponding to the unique identification number, thereby preventing the characters from being displayed on the screen. In order to display a character, the data information for the special character includes text information for that character in addition to the unique identification number.

As described above, the present invention provides a special character that expresses the user's emotion when creating a short message in a situation where it is difficult to support various character font styles for text input or received text messages when the short message is created in the mobile communication terminal. By including in the short message content, the visual aspect is displayed when displaying the short message. In addition, the present invention can be downloaded and used through a special character download service that provides a special character of various shapes and sizes according to their unique personality, so that by sending and receiving a short message containing their personality with friends according to the user's taste Make it fun
