Abstract

A character input method using a combination of initial sounds in a mobile communication terminal is provided to enable a user to input words which are perfect with only consonants by using a word DB that the user frequently uses in the terminal, thus the user can reduce an unnecessary action of repeatedly inputting words of high frequency together with vowels all the time. A controller checks whether consonants are inputted(301). If so, the controller checks whether a terminal is set to an automatic input mode for frequently used words(303). If so, the controller extracts word consisting of consonants(consonant strings), and displays the extracted word(305). The controller checks whether additional consonants are inputted(307). If not, the controller checks whether one of the extracted/displayed words is selected(309). If so, the controller converts the consonants into the selected word to output the word on a display(311).

The present invention relates to a character input method using an initial combination in a mobile communication terminal.

In recent years, with the development of communication technology, wired telephones as well as wireless telephones, particularly mobile phones, have been widely used so that individuals can always carry them. Currently, wireless phones are mainly used for PDAs and mobile phones, and provide various additional functions such as downloading games / videos, sending and receiving e-mails, and searching the Internet through the Internet as wireless Internet services are implemented.

However, now and in the future, the most important features of cordless phones are expected to be voice calls, text entry and transmission. For example, it is surveyed that students who are the most mobile phone age group mainly use voice calls and text transmission. In particular, the cost of texting on a mobile phone is much cheaper than the cost of a voice call, so students usually communicate by texting rather than voice calls. Therefore, in addition to improving the call quality, the mobile communication terminal manufacturer has been conducting a lot of research so that the user can easily enter text.

The conventional character input method is a method of inputting a desired spell by repeatedly pressing one button because several characters are assigned to one keypad button of a mobile communication terminal. In other words, by pressing the consonants and vowels several times, it causes the inconvenience of users. In particular, in the case of frequently used words, by inputting the vowels together every time, there is a problem that the speed of character input decreases due to unnecessary operations. In the conventional method, the sentence itself is stored and recalled so as not to repeatedly input the frequently used word. However, when there are several words that are frequently used, the conventional method is not only impossible to write in combination, but also increases the number of key presses, thereby degrading the speed and convenience of character input.

An object of the present invention is to provide a character input method using an initial combination in a mobile communication terminal.

Another object of the present invention is to provide a character input method that collects frequently used words in a mobile communication terminal and inputs them quickly and accurately by using an initial combination of the collected words.

According to an embodiment of the present invention to achieve the above object, in a character input method using a consonant combination in a mobile communication terminal, a process of checking whether a consonant (column) is input in a state in which a frequently used word automatic input mode is set; When the input of the consonant (column) is detected, a process of extracting a word composed of the consonant (column) from a database in real time, and sequentially converting the consonant (column) into the extracted word and outputting it to the display unit It is characterized by including.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In describing the present invention, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

Hereinafter, the present invention describes a character input method using the initial combination in the mobile communication terminal.

1 illustrates a configuration of a mobile communication terminal according to the present invention. In the following description, the mobile communication terminal is a cellular phone, a personal communication system (PCS), a personal digital assistant (PDA), an IMT-2000 (International Mobile Telecommunication-2000) terminal, or the like. It is meant to include all, the following description will be described with a general configuration of the above examples.

Referring to FIG. 1, a controller (MPU: Micro-Processor Unit) 101 controls the overall operation of the mobile communication terminal. For example, processing and control for voice communication and data communication are carried out, and in addition to the usual functions, the function for inputting characters using the initial combination according to the present invention is processed. Therefore, in the following description, description regarding the processing and control of the normal control unit 101 is omitted.

The ROM (Read Only Memory) 103 stores the microcode of the program and various reference data for processing and control of the controller 101. In particular, according to the present invention stores a program for inputting a character using the initial combination. A random access memory (RAM) 105 is a working memory of the controller 101 and stores temporary data generated during execution of various programs. The flash RAM 107 stores various updateable storage data. In particular, it stores the frequently used word data according to the present invention.

Key pad 109 is a numeric key buttons of 0-9, menu button (menu), cancel button (clear), confirmation button, call button (TALK), end button (END), Internet access button And a plurality of function keys such as navigation key (or direction key) buttons (▲ / ▼ / ◀ / ▶), and provide key input data corresponding to a key pressed by the user to the controller 101. The display 111 displays status information generated during the operation of the portable terminal, a limited number of characters, a large amount of video and still images, and the like. The display unit 111 may use a color liquid crystal display (LCD).

The codec (Coder-Decoder) 113 connected to the control unit 101 and the speaker 117 and the microphone 115 connected to the codec 113 are voice input / output blocks used for telephony communication and voice recording. . The codec 113 converts the digital data provided from the control unit 101 into an analog voice signal and transmits it through the speaker 117, and converts the voice signal received through the microphone 115 into digital data. Provided to the controller 101.

In addition, the radio frequency unit (RF) 121 lowers the frequency of the radio frequency signal received through the antenna 123 to the baseband processor 119 and provides the baseband signal from the baseband processor 119. The frequency is raised and transmitted through the antenna 123. The baseband processor 119 processes a baseband signal transmitted and received between the RF unit 121 and the controller 101. For example, in the case of transmission, the channel coding and spreading of data to be transmitted are performed, and in the case of reception, the function of de-spreading and channel decoding of the received signal is performed. To perform.

2 is a diagram illustrating a method for collecting frequently used words in a mobile communication terminal according to an exemplary embodiment of the present invention.

Referring to FIG. 2, in step 201, the controller 101 sets an item of 'word collection' according to a user's key manipulation. At this time, M is set to zero.

In step 203, the controller 101 checks whether there is a key input for message transmission. When the key input for transmitting the message is detected, the controller 101 adds the word included in the message to frequently used word data in step 205 and proceeds to step 207 to transmit the message. In this case, the word data is data stored in word units by breaking the content of the message based on a blank space and stored in a frequently used word database.

In step 209, the controller 101 checks whether M is smaller than N. N is the number of reference messages for the word collection and is related to the user's setting since it is related to the capacity utilization of the memory. When M is smaller than N, the control unit 101 proceeds to step 211 to update the value of M plus 1 to M, and returns to step 203 to check whether there is a key input for transmitting another message. do. When M is greater than or equal to N, the controller 101 ends word collection using a predetermined number N of messages and ends the algorithm according to the present invention.

Here, as a method for collecting the frequently used words, as described above, a word included in a predetermined number of outgoing messages may be stored, but the user may directly enter a specific word in the frequently used word database to save the word. You can also add data. Also, words and numbers stored in a phone book or a memo may be automatically added to frequently used word data regardless of a user's setting.

3 is a flowchart illustrating a text input method using an initial combination in a mobile communication terminal according to an exemplary embodiment of the present invention.

Referring to FIG. 3, in step 301, the controller 101 determines whether there is an input of a consonant according to a user's key manipulation. When the input of the consonant is detected, the controller 101 determines whether the terminal's mode is set to a frequently used word automatic input mode according to the user's setting in step 303. At this time, the user may set the priority according to each data collection path and time in the setting step. When the terminal is not set to a frequently used word mode, the controller 101 performs a general function of directly outputting the input characters to the display 111.

When the terminal is set to the frequently used word automatic input mode, the control unit 101 proceeds to step 305 to extract the word (s) consisting of the consonants (columns) from the frequently used word database, and the extraction The displayed word (s) on the display 111.

In operation 307, the controller 101 checks whether an additional consonant is input. When the input of the additional consonant is detected, the controller 101 returns to step 305 and extracts the word (s) including the additional consonant from the frequently used word database and displays it on the display 111. .

When the input of the additional consonant is not detected, the controller 101 determines whether one word of the extracted word (s) is selected according to a user's key manipulation in step 309. When the selection of one word is detected, the controller 101 proceeds to step 311 to convert the consonant into the selected word and output the consonant to the display 111 to terminate the algorithm according to the present invention.

For example, when a user wants to input 'Samsung Electronics' stored in the frequently used word data, the user may input the corresponding word only by inputting 'ㅅㅅㅈ'. In this case, the corresponding words are sequentially converted in real time and appear on the display 111. In other words, if you typed 'ㅅ', the word 'lion', if you typed 'ㅅㅅ', the word 'new god', if you typed 'ㅅㅅㅈ', the word 'new box', When you enter 'ㅅㅅㅈ', it can be converted to the word 'Samsung Electronics' in real time. If the word 'Samsung' has a higher priority, the word 'Samsung' comes from the beginning.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined not only by the scope of the following claims, but also by the equivalents of the claims.

An object of the present invention is to input a complete word using only a consonant using a word database frequently used in a mobile communication terminal, thereby reducing the unnecessary operation of repeatedly inputting a word frequently used with a vowel every time to increase the speed of character input. There is an advantage. In other words, a perfect Hangul input can be made at a high speed, and thus there is an advantage that user convenience can be increased.
