Description

Mobile Telecommunication Terminal Capable of Abbreviated Dialing and Control Method Thereof}

The present invention relates to a mobile communication terminal having a speed dialing function and a control method thereof. More specifically, a mobile communication terminal for displaying a list of telephone numbers having three or more input telephone numbers among a plurality of stored telephone numbers on the screen when three or more telephone numbers are input through a keypad. The present invention relates to a method for performing speed dialing using a mobile communication terminal.

Recently, with the rapid development of electronic engineering, communication engineering, and terminal technology, mobile communication terminals have various functions. That is, with the rapid development of wireless communication and data processing technology, people can use not only voice calls but also wireless Internet access, video communication and video message transmission using mobile communication terminals. In addition, due to the rapid dissemination of mobile communication terminals, mobile communication terminals are becoming an essential means of communication in modern life, such as a considerable amount of contact generated through human communication.

As the mobile communication terminal is used as an indispensable means of living for the modern people, the number of telephone numbers to be kept in order to communicate with the other party is also greatly increased. In the past, a user made a voice call by manually searching a phone number recorded using a writing instrument on a separate recording medium such as a notebook. However, as a function of storing a telephone number is implemented in a mobile communication terminal, a large number of telephone numbers and names of other parties (or business names or other user's recognition names) corresponding to the telephone number are stored together in the mobile terminal. Doing. The telephone number stored in the mobile communication terminal may be searched through a predetermined search process.

The telephone number search function provided by the conventional mobile communication terminal can be classified into three categories. First, search using a list of phone numbers on which recent calls have been made. Second, search using a location address stored with the phone number and the corresponding name of the corresponding party. Third, search for Korean or English. It is classified into a method of searching a phone number by inputting.

The first method is a method of sequentially searching a predetermined number (usually 10 to 20) of recent call lists stored in the mobile communication terminal using a scroll key, and the second method is a phone number and information of the other party. Memorizes the stored memory address and searches by entering a specific memory address when searching for a phone number. Finally, the third method is a method of searching for a phone number by directly inputting some or all of the letters forming the name of the person to be searched.

However, the conventional telephone number search method described above has the following problems or disadvantages. In the first search method, the number of phone numbers stored in the mobile communication terminal classified into the recent call list is usually limited to about 10 to 20, so it is not possible to search for a phone number other than the recently called phone number. There is this. Of course, it is possible to increase the number of recent call lists by increasing the memory space of the mobile communication terminal that stores the recently called phone number. However, in this case, the user must not only manipulate a lot of scroll keys to find the desired phone number. The disadvantage is that the search takes a lot of time. Therefore, it would be meaningless to increase the number of telephone numbers stored in the recent call list more than an appropriate number.

In the second method, in order to accurately input a memory address set in a telephone number to be searched for by the user, the memory address in which a person's name and telephone number are stored must be memorized one by one. However, the average user has a limit to memorize a large number of memory addresses accurately, and there is a disadvantage that a method of finding a phone number by inputting a memory address is generally not effective except for a few specific memory addresses that a user memorizes. have. Therefore, in general, a method of searching memory addresses sequentially from the first memory address until a desired telephone number is searched without inputting a specific memory address is mainly used, and thus, a lot of time is required for searching.

The third method is widely used as the most efficient method for searching a telephone number, but this method also has a problem that is derived as the mobile communication terminal becomes smaller and smaller. That is, in the case of a mobile communication terminal, the number of keys for inputting the other person's name (Hangul or English name) is limited, so the process of inputting Korean or English name is not easy to use. Therefore, there is a problem that the input process takes a lot of time.

Of course, various character input algorithms (Algorithm) have been developed and used to improve the inconvenience of the character input of such a mobile communication terminal, but the user spends a lot of effort and time to practice the character input operation smoothly must do it. In addition, as mobile communication terminals become smaller and smaller, and additional function keys are newly provided for various new functions, the interval between each key becomes narrower, so that other keys that are not desired by the user are pressed together with the desired key. It happens often. In addition, when searching the phone number through the other person's name, there is a problem that the search is difficult if you do not know the exact name of the person or if you do not exactly know the spelling (in particular English) of the person.

On the other hand, the recently released mobile communication terminal when the phone number is searched through the Hangul name to facilitate the search of the phone number using the third method, the first consonant of the first letter forming the Hangul name Search for a phone number by using the keyword as a search term, and also provides a function to search the phone number by using the first English letter of the English name as a search word. For example, if a user searches for a phone number stored in the Korean name "Hong Gil-Dong", typing "ㅎ" when searching for a name will search all names that start with "ㅎ" among the saved names. When searching for names, enter "J" to search for all names that start with "J" among the saved names.

However, this method has a drawback of the algorithm itself that the smaller the number of input letters or alphabets, the more people are searched. In other words, when one Korean consonant or an English alphabet is input, if there are many searched names, there is a problem in that a lot of scroll keys need to be manipulated to find a desired name in the search list. In addition, recent mobile communication terminals can store hundreds to thousands of phone numbers in a memory, and thus require a phone number retrieval method capable of minimizing a search target while requiring minimal data input for the user.

In order to solve the above problems, the present invention is a mobile communication to display a list of the telephone number having a three-digit telephone number or more among the plurality of stored telephone numbers when the telephone number is input through the keypad on the screen An object of the present invention is to provide a terminal and a method for performing speed dialing using the mobile communication terminal.
