Description

System and Method for searching internet domain name

The present invention relates to a domain name search system and a search method, and more particularly, to sequentially input a number corresponding to a character to be input through a number button of a keypad of a communication terminal device, and then to a domain name corresponding to the input number. The present invention relates to a domain name retrieval method and system for reading a database from a database and providing the same to a user's communication terminal device.

Recently, a communication terminal device capable of connecting to the Internet, for example, a portable telephone, a remote controller for web TV, a web phone, a PDA or a laptop capable of wireless communication, a GPS phone, and the like, has been developed. In general, they are provided with a keypad consisting of buttons which are assigned numbers and letters as input means.

Referring to FIG. 1, a keypad of a portable telephone is composed of number buttons 30 from 0 to 9 and function buttons 50 having special functions such as * and #, and each button 30 and 50. ) Are the letters A to Z and special characters.

That is, number button 1 is assigned., Q, Z, number button 2 is assigned A, B, C, number button 3 is assigned D, E, F, and number button 4 is assigned G, H, I. Are assigned, number buttons 5 are assigned J, K, L, number buttons 6 are assigned M, N, O, number buttons 7 are assigned P, R, S, and number buttons 8 are assigned T, U , V are assigned, and number 9 is assigned W, X, Y.

Accordingly, in order to input characters using the keypad, the numeric buttons to which the characters to be input are assigned are pressed in the order of arrangement. That is, to input "YES", press the number button 9 three times in short time interval and move the cursor, and then press the number button 3 two times in short time interval and move the cursor again. Press button 7 three times in a short time interval.

Therefore, it takes a considerable amount of time to enter a domain name to access the Internet, and a lot of accidental mistypes occur. For example, to access "YAHOO.COM" from the Internet, press the number button 9 with the letters W, X, and Y three times in succession to call the letter "Y". Press the number button 2 with the letters of 1 to call the letter "A." After a certain time, press the number button 4 with the letters G, H, and I two times in succession to call the letter "H." After a certain time, press the number button 6 with the letters M, N, O three times in succession to call the "O" character. After a certain time, press the number button 6 three times in succession to call the "O" character. .

Therefore, there is a problem that a considerable time is consumed and sophisticated hand gestures are required. Moreover, this is especially true when it is necessary to enter a top-level domain such as "COM" or "NET" or "CO.KR".

In addition, when the domain name is not known, a user needs to access a search portal site that the user knows and input a relevant search word to select and search for a site to be searched.

No. 2000-6804 (Name: Method and apparatus for digitizing Internet domain names using letters assigned to keypads of portable telephones), No. 2000-6094, filed by the present applicant to solve this problem. Name: Domain name search method using a mobile phone and a system using the same) and No. 2000-31739 (Name: Internet search method using a keypad of a mobile phone and a system using the same) in the domain of the website to be connected to the search server When a number corresponding to each letter constituting the name is sequentially input and transmitted, the search server generates a virtual domain name that can be implemented by sequentially combining the letters assigned to each number constituting the received numeric data, and the search server Domains where actual domain names are currently registered and managed through the domain name search engine Compare and search the virtual domain names generated from the name database to detect the matching real domain names, transmit the detected real domain names to the communication terminal device, and display the transmitted real domain names on the communication terminal device to display the actual domain. You can choose the domain name you want among the names.

However, this search method, there is a problem that puts a heavy load on the search server itself because it has to create a virtual domain name that can be implemented once.

In addition, there is a problem in that a lot of time is spent searching for a corresponding real domain name because a comparison must be made for each of the generated virtual domain names.

Accordingly, an object of the present invention is to provide a method for searching an Internet domain in which an actual domain name can be transmitted through a desired communication terminal apparatus without placing an excessive load on the search server.

Another object of the present invention is to provide a method for searching an Internet domain that can be provided with desired real domain names in a short time through a communication terminal device.

Other objects of the present invention will become more apparent from the following detailed description and the accompanying drawings.

According to the present invention, the communication terminal device is switched to the Internet mode, connected to the Internet, connected to a search server, and sequentially inputting numbers corresponding to each character constituting a domain name of a desired website, and being sequentially inputted. 1 When the numeric data is transmitted to the search server, the search server compares the received first numeric data with each of the second numeric data stored in the domain name database, and reads the actual domain names stored corresponding to the matching second numeric data. After extraction, the extracted real domain names are transmitted to the communication terminal device, the transmitted real domain names are displayed on the communication terminal device, and the desired domain name is selected from the displayed real domain names to access the desired website.

At this time, the actual domain names stored in correspondence with the second numerical data are arranged in the domain name database according to the order of accessing the Internet, and are displayed on the communication terminal device starting from the actual domain names having the highest order of access.

In the present invention, as a communication terminal device, a portable telephone, a remote controller for web TV, a web phone, a PDA, a laptop or a GPS phone capable of wireless communication, etc. may be used.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the description of the present invention, the terms defined are defined in consideration of functions in the present invention, which may vary according to the intention or customs of those skilled in the art and the definitions are based on the contents throughout the present specification. Will have to be lowered.

The communication terminal device applied to the present invention may be provided in various forms, and any device having a keypad composed of a plurality of keys sharing numbers and letters may be applied. For example, the present invention can be applied to a portable telephone, a remote controller for web TV or a web phone, a PDA, or a notebook capable of wireless communication.

Hereinafter, for convenience of description, a portable telephone will be described as an example.

2, there is disclosed an internet domain name search system according to an embodiment of the present invention.

The client 100, such as a mobile phone, a remote controller for a web TV or a web phone, a PDA, or a notebook capable of wireless communication, may be connected to the web server 400 through the Internet 300 via a repeater 200 corresponding to each device characteristic. It is connected to the search server 500.

The repeater 200 connects to a base station (not shown) when the user presses a phone number in order to make a call in the phone mode, and makes a call with the other party. When the user switches to the Internet connection mode, the repeater 200 is connected to the mobile phone. Connect the 100 and the Internet 300.

The web server 400 includes a domain name database 450 to store actual domain names on the Internet, update them regularly, and provide domain name data at the request of the search server 500.

The structure of the domain name database 450 applied to the present invention is shown in FIG. The web server 400 collects related information including domain names from servers connected to the Internet by using a search robot, and extracts only the domain name through proper processing to build a domain name database 450. At this time, the collected domain names are stored in the domain name database 450 by matching the numbers corresponding to the letters constituting the domain name.

For example, in "YAHOO.COM", "YAHOO" is sequentially connected, and the number on the keypad of the corresponding communication terminal device becomes "9-2-4-6-6" so that the domain name database ( 450), "92466" is stored in the numeric data field, and "YAHOO" is stored in the domain name field to form one record.

Therefore, a plurality of real domain names can be assigned to one numeric data. That is, as shown in FIG. 3, the numeric data "234" may be assigned an actual domain name "ADG", "BFI", "CDH", or the like.

In addition, when constructing a domain name database, the actual domain name can be arranged according to the rank frequently accessed on the Internet, if necessary, as will be described later, by transmitting the actual domain name to the user in accordance with the arranged rank to display By doing so, the user sees the domain name they frequently access, so they can make faster choices.

The search server 500 includes a domain name search engine 550 and receives a virtual data transmitted from the portable telephone 100 through the Internet 300, and can be implemented as a character assigned to each numeric data. After creating a data server

Search the database 450 and match the actual domain names to the Internet.

Transmit to the user's portable telephone 100 through 300.

Hereinafter, an Internet domain name search method according to a preferred embodiment of the present invention will be described in detail with reference to FIG. 4.

First, the user switches the portable telephone 100 to the Internet mode and connects to the Internet 300 through the repeater 200 (step S200).

After accessing the search server 500 of the operation site through the Internet 300, numerical data corresponding to the domain name of the site to be accessed is sequentially input (step S210). For example, to access the site YAHOO.COM, number 9 button containing the letter "Y", number 2 button containing the letter "A", number 4 button containing the letter "H" and letter "O" Enter the number button 6 including 6 and the number button including the next "O" sequentially. In this case, the numeric data input by the user is displayed on the LCD display window provided in the portable telephone.

Subsequently, when the user presses the search button provided in the portable telephone, the displayed numeric data “92466” is transmitted to the search server 500 through the repeater 200 connected to the Internet.

The domain name search engine 550 of the search server 500 receives the numeric data “92466” and compares the received numerical data with each of the numeric data stored in the domain name database 450 of the web server 400. The actual domain names stored in correspondence with the numeric data are read out and extracted (step S220).

In this case, as described above, the actual domain name corresponding to the numeric data “92466” may be a plurality including “YAHOO”. As shown in FIG. 1, a plurality of alphabetic characters are assigned to one number. This is because a combination of characters not registered in the English dictionary is most likely due to the nature of the domain name.

Thereafter, the search server 500 transmits the extracted real domain names to the user's mobile phone through the Internet 300 (step S230). In this case, as described above, when the actual domain names extracted from the search server 500 are transmitted to the user according to the order of connection, the display window of the sized portable telephone is displayed from the domain name having the highest connection order. You'll be able to choose your domain name sooner.

When the real domain names transmitted from the search server 500 are displayed on the LCD display of the portable telephone, the user selects a desired domain name from among the plurality of real domain names (step S240), and then accesses the desired site through the Internet 300. (Step S250).

As described above, according to the present invention, the load on the search server can be significantly reduced. For example, conventionally, when the numeric data "92444" corresponding to "YAHOO" is input, the W, X, Y characters assigned to the number 9 button, the A, B, C characters assigned to the number 2 button, , A combination of the letters G, H, and I assigned to number 4, the letters M, N, and O assigned to number 6, and the letters M, N, and O assigned to number 6 Generate domain names. In this case, the generated virtual domain names are all 3 ⁵ = 405, for example, WAGMM, WAGMN, WAGMO, ....., YCIOO, and the like. As a result, the search server is subject to significant load because each of these 405 virtual domain names must be compared with the actual domain name, and this load is received each time a search request is made from the user. Moreover, if the number entered is large, the number of virtual domain names accordingly increases exponentially.

On the other hand, according to the present invention, the domain name database in which the actual domain names are matched with the combination of the numbers of the corresponding keypads is stored in advance in the web server, and the actual domain names match the numerical data received from the user's communication terminal device. Searching domain names can significantly reduce the load on the search server itself, and can also reduce the time spent searching.

Although described in detail with respect to preferred embodiments of the present invention as described above, those of ordinary skill in the art, without departing from the spirit and scope of the invention as defined in the appended claims Various modifications may be made to the invention.

For example, in addition to the portable telephone as in the embodiment, the communication terminal apparatus may be equipped with a key pad such as a remote controller for web TV, a web phone, a PDA or a laptop capable of wireless communication, a GPS phone, etc. Can be.

In addition, the present invention can be applied and used in various aspects. For example, if you build an English word database consisting of matching numeric data, English words and word meanings on a web server, and input the numeric data from the keypad, the search server will match the English words that match the received numeric data. The meaning of the word is transmitted to the user, and the user can select a desired word to grasp the meaning of the English word.

Such various modifications can be easily made to those skilled in the art, and such modifications will naturally be within the scope of the applicant.

As described above, according to the present invention, there is an advantage in that the actual domain name can be transmitted through a desired communication terminal apparatus without putting an excessive load on the search server.

In addition, there is an advantage that the desired real domain names can be provided in a short time through the communication terminal device.
