Description

How to search phone number on phone with display unit {METHOD FOR SERCHING TELEPHONE NUMBER IN TELEPHONE HAVING DISPLAYING UNIT}

The present invention relates to a method for searching a telephone number in a telephone having a display, and more particularly, to a method for quickly and easily searching for a telephone number.

Typically, telephones have been developed as a means for voice calls, which can now accommodate not only voice calls but also data communications, and at the same time accommodate a variety of additional functions. In addition, the display unit on the first telephone appeared as a means for easily confirming the user entered telephone number, etc. and is now almost used in a mobile communication terminal or a key phone, and is generally adopted and used in a home telephone. Among the additional functions of the telephone, a telephone having a display unit adds a telephone directory function by inputting a telephone number and a corresponding person's ID into a memory, and at the same time stores a recent calling number.

However, many users do not know how to use the function of the phone book provided in the telephone, and many people use this function as a means of simply inputting a telephone number. The phone book function is also used in conjunction with the speed dial function. In this case, if you want to make a call, you must know the speed dial number for each person. Therefore, most of the users do not feel comfortable using it in most cases.

In addition, even if you use this function, you can simply use the phone book to search by entering a large number of keys, or find a phone number through a large number of key input to enter a name. In this case, a large number of key inputs are required rather than actually dialing. Therefore, users have a problem of making a phone call separately from storing the memory in a real phone or entering a phone number one by one.

Accordingly, an object of the present invention is to provide a phone number search method for easily and conveniently searching for and displaying a phone number in a phone having a display unit.

The present invention for achieving the above object is a telephone number search method in a telephone having a display unit and a predetermined memory, when the key data for dialing is received in the telephone number input mode, the key data entered in the recent caller number table. A first step of searching whether the same number exists in the same digit as and a display process of displaying a subsequent digit of the input key data on the display unit if the same data exists as the first search result, and the next key data A process of checking whether there exists, a process of proceeding to the first process when the next key data exists, a dialing process of dialing the displayed number when a call key is input in the display process; If the same number does not exist in the recent caller number table, search for the registration table. And a second step of searching whether the same number in the same place and ryeokdoen key data exist and, if not, the same number present in the second search process to the first search process, the process of performing the normal display mode and,

The display process,

To distinguish between the number that the key data is received and displayed and the display of the subsequent number that matches the search result without receiving key data,

And when the key data for dialing is received in the telephone number input mode, proceeding to the first search process when the number of digits is more than a predetermined digit.

The dialing process,

The dialing is performed except for the telephone number input during the dialing.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. The same parts also use the same reference numerals, although shown in the other figures.

1 is a block diagram of a mobile communication terminal to which the present invention is applied. Hereinafter, the configuration and operation of a mobile communication terminal to which the present invention is applied will be described in detail with reference to FIG. 1. In addition, this can be used in all phones having a display unit and a predetermined memory, but will be described using a mobile communication terminal.

The control unit 111 controls the overall operation of the mobile communication terminal. In particular, according to the present invention, the controller 111 performs a control of searching for a telephone number stored in a memory and displaying it on a predetermined display unit. The antenna ANT transmits a radio signal through air waves or receives an air wave signal and outputs it to the duplexer 112. The duplexer 112 transmits a radio signal received from the antenna ANT to the receiver 113, and transmits a radio signal received from the transmitter 115 to the airwaves through the antenna ANT. The receiver 113 converts and outputs only a signal corresponding to a channel of a frequency band set by the controller 111 of the radio signals received from the duplexer 112 into a baseband signal or data. The transmitter 115 converts the baseband signal or data into a frequency to be transmitted under the control of the controller 111 and outputs the signal to the duplexer 112. The frequency synthesizing unit 114 generates and outputs a frequency to be output to the receiving unit 113 and a frequency to be output to the transmitting unit 115 under the control of the control unit 111. The antenna ANT, the duplexer 112, the receiver 113, the frequency synthesizer 114, and the transmitter 115 are collectively referred to as a wireless unit 101.

The voice processor 116 decodes the baseband coded signal received from the receiver 113 and outputs the decoded signal to the speaker SPK. The voice processor 116 codes the signal received from the microphone MIC and outputs the signal to the transmitter 115. The speaker SPK outputs the decoded and input electrical signal as an audible sound, and the microphone MIC converts the audible sound signal into an electrical signal and outputs it to the voice processor 116. The memory 117 has an area for storing data necessary for controlling the terminal and an area for temporarily storing data generated during control. In addition, the memory 117 stores a list of recent dialing numbers for storing recently dialed telephone numbers in the form of a table, and such a table can be configured differently according to the size of a memory area, and 20 telephone numbers can be configured. When illustrated as storing, it can be shown as Table 1 below.

turn Phone number One 123-4567 2 011-789-0123 3 011-9897-4921 ― ― 20 017-321-2348

In this table, the most recently dialed telephone number is stored in the earliest sequence number 1, and the oldest dialed telephone number is stored in the latest sequence number 20. In addition, in the following description, a table for storing recently dialed telephone numbers, such as <Table 1>, is referred to as a 'recent call number table'.

In addition, the memory 117 is configured to perform a function of the phone book, and even when the phone book is provided, the number of the stored phone number is different according to the size of the area of the memory. For example, when 200 telephone numbers are stored, the same may be illustrated in Table 2 below.

Shortcut number Phone number name 001 02-423-3921 A castle house 002 011-762-8121 Angel 003 017-322-2348 Hwang Eun Jung ― ― ― 199 017-219-0179 Kim Hyun Kook 200 011-727-8929 Jun Hwan Ahn

As shown in Table 2, the function of the phone book is usually configured to perform speed dialing in response to a specific key without merely storing a phone number and a name. In the following description, a table such as <Table 2> will be referred to as a 'registration table'.

The key input unit 118 has a key matrix structure (not shown in FIG. 2), and generates key data corresponding to a key pressed by the user and outputs the key data to the control unit 111. The display unit 119 may display a current state of the terminal, an operation process, and the like under the control of the controller 111, and may display a display battery remaining amount of the watch. In addition, the display unit 119 may be configured using a liquid crystal display panel or the like, and displays data corresponding to a key input when a key is input. In addition, the display unit 119 displays the retrieved telephone number using the first few digits when the user inputs the telephone number according to the present invention. Accordingly, the user operates the terminal through the key input unit 118 and the display unit 119.

2 is a control flowchart of a mode in which a telephone number is dialed according to a preferred embodiment of the present invention. Hereinafter, a mode in which a telephone number is dialed according to the present invention will be described in detail with reference to FIGS. 1 to 2. In addition, in the following description, a mode for inputting a phone number for dialing is referred to as a 'phone number input mode'.

The controller 111 receives the key data from the key input unit 118 in the phone number input mode and displays it on the display unit 119. The controller 111 displays key data received from the key input unit 118, and proceeds to step 202 to check whether the key value is 2 or more. In this case, checking whether two or more conditions are satisfied is that the condition of the number of digits for the search is satisfied. Such digits may be set to one or may be set to three or more. In the present embodiment, an example set to 2 will be described. The control unit 111 repeatedly performs steps 200 and 202, and proceeds to step 204 when the key value becomes 2 or more. The controller 111 first checks the latest calling number table in step 204. This will be described with reference to FIGS. 3A to 3C.

3 is a diagram illustrating only a portion for displaying a phone number of the liquid crystal display.

First, assume that the two-digit telephone number entered by the user is '01'. Then, '01' is displayed on the display unit 119, and the control unit 111 proceeds to step 204 to search for the latest call number table provided in the memory 117. The controller 111 proceeds to step 206 to check whether the same number exists. If the same number exists as a result of the test, the process proceeds to step 214, and if not, the process proceeds to step 208. First, the case where the same number exists is demonstrated.

If the same number is present and the process proceeds to step 214, the first two digits of the searched phone number are displayed without being inputted after the last digit of the most recently dialed phone number of the same phone number by a reversed method. Indicates data and displays it. That is, if it has a table as shown in Table 1, it will be shown as shown in FIG. That is, '01' performs a general display, and since there is a most recently stored telephone number of 011-123-4567 among the matching numbers among the telephone numbers retrieved from the recent caller number table, since the position is' 1-123- The portion of 4567 'is shown in reverse. The controller 111 proceeds to step 216 to check whether key data for the next digit is received from the key input unit 118. When key data for the next digit is input as a result of the check, the process proceeds to step 204. However, if the result of the check is not a key signal for the next digit, the control unit 111 proceeds to step 218 and checks whether key data corresponding to the call key is input. If key data according to the call result is input, the process proceeds to step 220 to perform the call mode, otherwise proceeds to step 222. When the controller 111 proceeds to step 222, the controller 111 determines whether a key signal corresponding to termination is received from the key input unit 118. When the key signal corresponding to the termination of the test result is received, the control unit 111 ends the control routine of the telephone number input mode. Otherwise, the control unit 111 proceeds to step 216.

Then, the case proceeds from step 216 to step 204. When the next key data is received in step 216, the controller 111 displays it on the display unit 119, and proceeds to step 204. In this case, when the digit after the inputted telephone number is 1, that is, when all the digits entered are '011', '123-4567' is displayed in reverse in the display unit 119. When the next seat is received in step 216 again, the process proceeds to step 204. In this case, the movement to the next digit may be performed by inputting the next key, or in the case of the same key data, the cursor may be moved to input after the digit. That is, when '01' is input and '011' is input, the '1' key may be input or the cursor may be moved using the cursor movement key.

In addition, if the inputted telephone number is '7' after the input up to '011' is terminated, the controller 111 searches the latest caller number table in step 204. At this time, since the phone number '011-789-0123' exists in the recent calling number among the searched phone numbers, '011-7', the number entered among the phone numbers, is normally displayed on the display unit 119, and the number thereafter. '89 -0123 'is displayed in reverse. That is, it is shown in the form as shown in (b) of FIG. When the phone number is input again in step 216, the controller proceeds to step 204 again. In this case, when the inputted telephone number is '6', that is, when the number of the telephone number inputted so far is '011-76', the controller 111 searches for the latest calling number table in step 204 again. In step 206, it is checked whether the same number exists. If the phone number corresponding to '011-76' does not exist in the recent caller number table when it is configured as shown in <Table 1>, the process proceeds to step 208 to check the registration table.

In the following description, the registration table will be described in Table 2. Then, the controller 111 searches for the telephone number corresponding to '011-76' in the registration table when proceeding to step 208. In step 210, the same number is checked. If the same number is present, the controller 111 proceeds to step 214. Otherwise, the controller 111 proceeds to step 212 to terminate the reverse phase display and then performs general display on the display unit 119.

However, according to <Table 2>, since there is a telephone number corresponding to '011-76', the process proceeds to step 214 to display the matched telephone number in reverse, and to input the next digit data or the call key. Input checks or exit key checks are performed. In addition, when the telephone number is retrieved from the registration table, when the next key data is input again, the registration table may be examined to proceed to step 208. In addition, it may be configured to search by reversing the search order of the recent call number table and the registration table, and may also be configured to search for and display sequentially if there is another table that stores the phone number.

In addition, in the case of a general telephone, it is necessary to continuously generate DTMF tones, so when the call key is provided, the call key may be configured to sequentially transmit DTMF tones corresponding to the numbers of the parts displayed in reverse.

As described above, when the user inputs a phone number, the user searches for the same phone number and displays it, and when the call key is input, the call can be easily made. In addition, there is an advantage that the user can use the registration table and the recent calling number table of the phone number that is not used properly. In addition, if you do not remember the phone number, for example, remember only the first two or three digits except the previous service provider, and if you do not remember the digit after that, the phone number is dialed or registered. There is an advantage to making a call.
