Mobile Telecommunication Terminal Capable of Searching Telephone Number by Using Multiple Keyword and Control Method Thereof}

The present invention relates to a mobile communication terminal having a telephone number search function using multiple search terms and a control method thereof. More specifically, after searching a plurality of phone numbers stored in the mobile communication terminal using the Hangul consonant or alphabet (Alphabet) input to the mobile communication terminal as the first search word, MIN (Mobile Identification Number), general wired or wireless telephone The present invention relates to a mobile communication terminal having a telephone number search function using multiple search terms for re-searching a list of previous search results using a number, a local station number, etc. as a second search term, and a control method thereof.

As is well known, recent advances in electronics and telecommunications engineering have resulted in a variety of mobile terminals. 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 contact with the other party is also greatly increased. In the past, a user recorded and used a telephone number by 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 now stored and used in the mobile terminal. Doing. The telephone number stored in the mobile communication terminal may be searched through a predetermined search process.

The phone number search function provided in the conventional mobile communication terminal can be classified into three categories. First, a method of searching using a list of phone numbers on which a recent call has been made, and second, a phone number and the name of the other party corresponding thereto. This method is classified into a method of searching using a stored address and a method of searching a telephone number by inputting Korean or English.

The first method is to save a certain number (usually 10) of recent call list and search the stored recent call list sequentially by using scroll key. The second method is to call the phone number and the other party's information. Saves the stored address and searches directly by entering a specific address when searching the phone number. Lastly, the third method is a method of searching for a phone number by directly inputting all or part of 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, which is classified into the recent call list, is usually limited to about 10, which makes it impossible to search for a phone number other than the recently called phone number. . 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, but this requires not only the user to manipulate the scroll keys a lot 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.

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 (Korean or English name) is limited. The problem is that the process takes a lot of time.

Of course, various character input algorithms (Althorithm) have been developed and used to improve the inconvenience of the character input of the mobile communication terminal, but the user spends a lot of effort and time to practice the character input work 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 not possible if you do not know the exact name of the person or do not know the exact spelling 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 Searching for a phone number by using a search term, and searching the phone number using the first English letter forming the English name as a search term is provided. 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 an algorithmic disadvantage that the number of letters searched is increased as the number of input letters or alphabets decreases. 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 telephone numbers in a memory, and thus require a telephone 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, after searching a plurality of phone numbers stored in the mobile communication terminal using the Hangul consonant or alphabet (Alphabet) input to the mobile communication terminal, MIN, general wired and wireless An object of the present invention is to provide a mobile communication terminal having a phone number search function using multiple search terms for re-searching a list of previous search results using a phone number, a local station number, and the like as a second search term, and a control method thereof.

It is. The phone number search program may search for a phone number and a person's name (or a business name or a recognized name of another user) stored in the mobile communication terminal 100 according to a search word input through the key input unit 104 by the user. Perform. The telephone number retrieval program according to an embodiment of the present invention may be coded using C ⁺⁺ or JAVA, which is an object-oriented language. The search word according to an embodiment of the present invention may be classified into a first search word and a second search word and may be input or selected. This will be described in more detail with reference to FIG. 2.

In addition, the phone number search program implements a screen related to a phone number search and a screen for displaying a list of phone number search results. That is, the phone number search program is driven when the user selects the phone number search menu to generate and display a screen for searching a phone number and to display a list of the search results generated on the LCD screen.

The key input unit 104 is provided with a plurality of key buttons for inputting numbers such as telephone numbers. Such key buttons typically include 12 numeric keys (0 to 9, *,,), multiple function keys, multiple cursor movement keys, scroll keys, and the like. Accordingly, the user selects a phone number search mode by operating a numeric key, a function key, a direction key, a scroll key, etc. included in the key input unit 104, and selects a first search word and a second search word to search for a desired phone number. can do.

The LCD display unit 106 generally displays an operation state of the mobile communication terminal 100 including a state of use of a battery, a reception strength of radio waves, a date and a time. In addition, according to an exemplary embodiment of the present invention, the LCD display unit 106 displays a first search word selection area and a second search word selection area and a list of telephone numbers searched according to the selected first search word and the second search word on one screen.

The data storage unit 108 generally serves as a data buffer when executing an operation program of the mobile communication terminal 100 and temporarily stores data input by the key input unit 104 or performs mobile communication from the outside. The terminal 100 stores data such as a text or an image received by the terminal 100. In addition, according to an embodiment of the present invention, the data storage unit 108 stores a list of search results temporarily generated when the phone number search program stored in the program memory 102 is driven.

That is, the phone number search program temporarily stores the first search result list for the first search word input from the microprocessor 114 in the data storage 108 and stores the second search term input from the microprocessor 114. The second search result list searched using the data is also temporarily stored in the data storage 108. Here, the second search result list refers to a list including the search results searched by applying the second search word from the first search result list. Of course, the first search result list and the second search result list are displayed via the LCD display 106. In addition, when the second search word is input through the key input unit 104 while the first search result list is displayed on the LCD display, and the phone number search program generates the second search result list, the first search result list is stored in the data storage unit ( Deleted at 108 and at the same time is deleted at LCD display 106 as well.

The mode state storage unit 110 stores the current operation mode of the mobile communication terminal 100 selected by the key input unit 104 as a state flag (eg, 0, 1, 2,...). That is, the microprocessor 114 assigns a unique status flag to each mode to distinguish whether the mobile communication terminal 100 is an incoming mode, an outgoing mode, a search mode, a storage mode, or a call mode. The mode state storage unit 110 is updated.

The subscriber information storage unit 112 stores registration information of a subscriber, that is, a user. The subscriber information storage unit 112 is also called a SIM card because it is inserted into a slot in the form of a card, and performs an interface function between the mobile communication terminal 100 and a communication network. The SIM card stores a mobile identification number (MIN), a personal security key, and various data necessary for the operation of the mobile communication terminal 100 (general wired / wireless telephone number, personal name, etc.) and is installed in the mobile communication terminal 100. When the card is removed and installed in another terminal, voice and data communication can be performed. That is, when the power of the mobile communication terminal 100 is turned on, the mobile communication terminal 100 transmits and receives all the information in the SIM card to the mobile communication network. do. The subscriber information storage unit 112 stores the telephone number and the personal information corresponding to the telephone number input through the key input unit 104 in a separate telephone number storage area.

The microprocessor 114 controls the overall operation of the mobile communication terminal 100 based on the state flag stored in the mode state storage unit 110. In particular, when the phone number search mode is selected by the key input unit 104, the microprocessor 114 drives a phone number search program stored in the program memory 102, and searches for a phone number according to one or more selected search terms. Perform display operations. To this end, when the phone number search mode is selected, the microprocessor 114 generates a control signal of the phone number search mode and transmits the control signal to the mode state storage unit 110, and when one or more search terms are selected, the phone number driving the corresponding search value. Pass it to the search program.

In addition, the microprocessor 114 performs a call function by switching to the call mode when the call button is selected while the cursor is located on a specific phone number in the phone number search mode, and when the delete button is selected, the subscriber information storage unit 112 is selected. Delete the selected phone number in the phone number field of the). In addition, when the edit button is selected in the phone number search mode, the microprocessor 114 switches to the edit mode for editing the selected phone number. Meanwhile, the microprocessor 114 transmits digital data for performing various functions requested through the key input unit 104 to the baseband converter 118 (TX DATA).

The DSP 116 is a digital signal processing processor that codes or decodes a speech signal, functions as an equalizer for multipath noise cancellation, and performs an acoustic data processing function. Also, the DSP 116 exchanges voice data SPEECH with the baseband converter 118 and receives digital data RX DATA from the baseband converter 118.

2 is an exemplary screen showing a process of searching for a telephone number using the mobile communication terminal 100 according to the first embodiment of the present invention.

Referring to FIG. 1, FIG. 2A shows an initial screen of a phone number search mode, in which phone numbers can be stored in various groups. That is, the user inputs a new phone number using the mobile communication terminal 100, and stores a phone number by specifying a group name (1. full name, 2. family, 3. restaurant, etc.) to which the input phone number belongs. Can be. Therefore, the user can search the phone number for each group even in the phone number search mode, so that the user can search the desired phone number more accurately and quickly. For example, if the user selects the "1. full name" item in FIG. 2A, all the phone numbers stored in the subscriber information storage unit 112 are displayed. If the user selects the "2. family" item, the subscriber information storage unit 112 is displayed. Only the phone numbers belonging to the family group are displayed among the phone numbers stored in).

Meanwhile, as shown in FIGS. 2B to 2D, the phone number search mode screen according to an embodiment of the present invention includes a first search word selection area for selecting a first search word, a second search word selection area for selecting a second search word, and a search result list This includes the displayed search result list area. As a search word included in the first search word selection area according to an exemplary embodiment of the present invention, a whole, a Korean consonant (B, B ... H), an alphabet (A, B ... Z), and the like may be used. In addition, the search terms included in the second search word selection area include ascending, descending, moving, general, mobile communication service provider identification numbers (011, 016, 017, 018, 019), regional station numbers (02, 031, 032, 033, 041, 042, 043, 051, 052, 053, 054, 055, 061, 062, 063, 064), foreign countries, etc. are possible.

When defined for a search word according to an embodiment of the present invention as illustrated in Figure 2 'all' is a search word that randomly displays all phone numbers or names stored in the mobile communication terminal 100, Hangul consonant or alphabet Is a search word that displays a person's name beginning with the Hangul consonant or alphabet.

In addition, 'ascending' is an item for sorting a phone number or a person's name stored in the mobile communication terminal 100 in an ascending order, and 'Descending' is an item for sorting in a descending order. Here, ascending order is Hangul consonant 'ㄱ'-> 'ㄴ'-> ...-> 'ㅎ' order, 'A'-> 'B'-> ...-> 'Z' of the alphabet The descending order is to classify people. Of course, the ascending and descending order applied to the embodiment of the present invention may be used in the opposite meaning. In particular, when "all" is selected as the first search word, the ascending or descending order will be determined by the coding content of the telephone number search program mounted in the mobile communication terminal 100. For example, when the mobile communication terminal 100 is manufactured, the ascending order may be determined by the order of image-> number-> Korean-> foreign language, etc. Alternatively, the order of foreign language-> Korean-> number-> image may be determined. There will be.

On the other hand, 'mobile' is a search term that searches only the phone number of the mobile communication terminal 100 (mobile phone, PD, etc.) separately, and 'general' is a general wired / wireless phone number among the phone numbers stored in the mobile communication terminal 100. Only search terms are separately. In addition, each mobile communication provider identification number and area number is a search word for searching for a phone number having a corresponding number system. In addition, 'foreign' is a search word for separately searching for a phone number used in a foreign country other than a domestic phone number or a MIN among phone numbers stored in the mobile communication terminal 100. In particular, the term 'foreign' search term may be used as a useful function because IMT-2000-only terminal is commercialized and a worldwide roaming service may be provided.

Meanwhile, in the phone number search mode screen of FIGS. 2B to 2D, the cursor movement to each keyword in each keyword selection area may be performed by pressing the left and right arrow keys, and the cursor movement in each keyword selection area may be performed. This can be done by pressing the down arrow key. In addition, only a part of search words are displayed in each search word selection area of FIGS. 2B to 2D, but when a cursor is located at the far right end of the selection area, a user inputs a predetermined key button (for example, a right side) provided in the key input unit 104. Direction key), the search terms of each search word selection area are sequentially disappeared to the left side of the LCD screen, and other search terms appear one by one from the right side of the LCD screen in a preset order. On the contrary, when the cursor is located at the far right end of the selection area, pressing the left arrow key in turn causes the search terms of each search word selection area to disappear to the right of the LCD screen and other search terms appear one by one from the left side of the LCD screen.

Meanwhile, according to an embodiment of the present invention, there are various methods for determining whether a search word is selected. For example, a method of determining that a search word is selected at the same time a cursor is positioned at each search word in each search word selection area. This method has the advantage of reducing the number of key operations and the search time since the list of search results is displayed without pressing a separate selection key. However, there is a disadvantage in that an operation amount of the phone number search program is increased. Another method is to determine that a search word is selected only after a cursor is positioned on each search word in each search word selection area and then a separate selection key is pressed. This method has the disadvantage of increasing the number of key operations and retrieval time, but has the advantage of reducing the computational work of the telephone number retrieval program.

In addition, while the first search word is selected and the first search result list screen is displayed, the second search word is selected and the second search result list screen is generated. However, the phone number search using the reverse process is also described. It is possible. That is, the second search term is first selected in the previous search process, and then the first search term is selected in the current search process. For example, when a specific search word in the first search word selection area is selected while the second search result list screen of the previous search process is displayed, the second search term selected in the previous search process is automatically set as the second search term of the current search process. Number search is in progress. Therefore, the user does not have to select the second search word separately only by performing a search word selection process of selecting the first search word.

In addition, when the call button, delete button, and edit button are selected while the cursor is positioned on a specific person or phone number in the search result list area, the microprocessor 114 may control the mobile communication terminal 100 in call mode, delete mode, and edit, respectively. Switch to mode.

2B to 2D show that “1. full name” is selected by the key input unit 104 in the telephone number search initial screen of FIG. 2A, and “all”, “all”, and “b” respectively as the first search word. Is an example screen when "up", "011" and "011 are selected as the second search word, respectively. Of course, if a specific item is selected on the initial search number screen of FIG. 2A," all "as shown in FIG. It is preferable that "and" rising "are automatically set to the first search word and the second search word so that the search result list is displayed on the mobile communication terminal 100.

The icon of a mobile phone displayed on the right side of the name of each search result list area of FIGS. 2B to 2D indicates that there is a telephone number of the mobile communication terminal, and the icon of a house indicates that there is a general wired or wireless telephone number. Indicates.

3 is an exemplary screen illustrating a process of searching for a telephone number using the mobile communication terminal 100 according to the second embodiment of the present invention.

In the phone number search screens of FIGS. 2B to 2D according to the first embodiment of the present invention, Korean consonants and mobile operator identification numbers are displayed one by one from the left to the right of the screen. It may be inconvenient to select Hangul consonant or specific mobile carrier identification number. Accordingly, in the second embodiment of the present invention, unlike the example screens of FIGS. 2B to 2D, the operation of the operator is facilitated in various software such as the Internet web browser, word processor, graphic program, and the like. The search word of the search screen is displayed by one top-down method of a menu display method.

As shown in FIG. 3, the first search word according to the second embodiment of the present invention includes “all”, “Korean”, “English”, and “Japanese”, and the second search word includes “up”, “ "Down", "move", "general" and "foreign". When selecting "Hangul" in FIG. 3A, Korean consonants are displayed to the right of the search word "Hangul" as shown in FIG. 3B. Therefore, the user may immediately select a specific Hangul consonant that he wants to search. Of course, when "English" and "Japanese" are selected in FIG. 3A, the alphabet and Hiragana / Katakana are displayed in the same manner as in FIG. 3B. In FIG. 3, only Korean, English, and Japanese are displayed as the first search word. However, the technical spirit of the present invention is not limited thereto, and other foreign languages such as French, German, and Spanish may be added.

Meanwhile, FIG. 3B is a first search result screen when “b” is selected among Korean consonants displayed in the top down area, and FIG. 3C is a top view where a “move” search word is selected and displayed on the first search result screen of FIG. 3B. This is the second search result screen when "011" is selected in the down area. By using the top-down method as described above, all the search words of the first search word selection area or the second search word selection area may be displayed on one screen. Accordingly, the user can easily and conveniently select a desired search word without moving the screen itself of the search word selection area from side to side as described with reference to FIG. 2.

4 is a flowchart illustrating a process of searching for a telephone number using the mobile communication terminal 100 according to an embodiment of the present invention.

A user who wants to check a phone number stored in the mobile communication terminal 100 according to an embodiment of the present invention operates a predetermined function key provided in the key input unit 104 of the mobile communication terminal 100. Select a search mode (S400).

The microprocessor 114 that receives the key value of the phone number search mode through the key input unit 104 performs a task of setting a flag of the mode state storage unit 110 to the phone number search mode value. Switch to the phone number search mode (S402).

When the mobile communication terminal 100 is switched to the telephone number search mode, the microprocessor 114 drives the telephone number search program stored in the program memory 102 (S404).

The microprocessor 114 checks whether the first search word (= key value assigned to the first search word) selected by the user is transmitted from the key input unit 104 (S406).

When the microprocessor 114 receives the first search word from the key input unit 104 in step S406, the microprocessor 114 transmits the received first search word to a running phone number search program, and the received phone number search program is a subscriber. The person name and / or phone number stored in the phone number area of the information storage unit 112 are searched (S408).

The phone number search program generates a first search result list and displays the first search result list on the LCD display unit 106 when a search for a person name and / or a phone number that satisfies the first search term is completed (S410). Here, the first search result list is temporarily stored in the data storage unit 108 of the mobile communication terminal 100.

Then, the microprocessor 114 transmits the second search word selected by the user (= key value assigned to the second search word) from the key input unit 104 while the first search result list is displayed on the LCD display 106. It is checked whether or not (S412).

When the microprocessor 114 receives the second search term from the key input unit 104 in step S412, the microprocessor 114 may satisfy the conditions of the second search term received from the first search result list stored in the data storage unit 108. / Or search the phone number (S414).

The telephone number search program generates a second search result list and displays the second search result list on the LCD display unit 106 when a search for a person name and / or a telephone number that satisfies the condition of the second search word is completed (S416). At this time, the first search result list stored in the data storage unit 108 is deleted, and the second search result list is temporarily stored in the data storage unit 108.

On the other hand, the microprocessor 114 continuously checks whether the release key value of the telephone number search mode is input through the key input unit 104 while the telephone number is searched by the user on the second search result list screen (S418). ).

If it is determined in step S418 that the release key value of the phone number search mode is input, the microprocessor 114 releases the phone number search mode of the mobile communication terminal 100 (S420). Here, the release of the phone number search mode refers to a case where the operation mode of the mobile communication terminal 100 is switched to a mode other than the phone number search mode (standby mode, voice call mode, data communication mode, etc.).
