2 is a diagram schematically showing an entire system for performing an international call service providing method using a plurality of input windows according to an exemplary embodiment of the present invention.

2, the entire system for performing an international call service providing method using a plurality of input windows according to the present invention includes a user terminal 100, a communication network 110, at least one Internet service access device 120 and It comprises a plurality of information providing servers (130a, 130b, ..., 130n-hereinafter referred to as 130).

The user terminal 100 is a communication terminal capable of using a wireless internet service as well as a call service such as a voice or video call through the communication network 110. The user terminal 100 may be, for example, a personal digital assistant (PDA), a notebook computer, or the like, as well as the mobile communication terminal 10 illustrated in FIG. 1. In particular, the user terminal 100 according to the present invention may use a call service and / or a wireless Internet service not only in the home country but also abroad. That is, the user terminal 100 is a communication terminal capable of using international roaming service.

The user terminal 100 according to the present invention executes an international call input mode for inputting a telephone number for an international call when a predetermined specific key button is operated. In particular, the international call input mode according to the present invention can input not only an international phone number but also a character string, and can perform internet search, Internet access, etc. using the input character string. The configuration and operation of the user terminal 100 will be described in detail with reference to the accompanying drawings.

The communication network 110 is wireless as well as a wireless telephone network such as a wideband code division multiple access (WCDMA) network and a global system for mobile communication (GSM) network that provides a call service and / or a wireless Internet service to an access user terminal 100. Packet switched network, or the like. In particular, the communication network 110 according to the present invention may provide a roaming service to the user terminal 100. That is, even when the user terminal 100 requesting a call service or a wireless Internet service is a terminal roaming from a foreign country instead of a domestic terminal, the communication network 110 according to the present invention may provide not only a call service but also a wireless internet service. Can be. International roaming call services are becoming more common, but data services such as wireless Internet services are still weak. It is assumed that the communication network 110 according to the present invention can provide the same wireless Internet service to a terminal roaming from a foreign country instead of a terminal subscribed to a domestic station.

Although not shown, the communication network 110 includes a base station, a base station controller, a switch, an interworking function (IWF), a packet data serving node (PDSN), and a roaming service providing apparatus for roaming services. (Of course, the roaming service may be provided by a mobile communication network device such as an exchanger). Communication networks such as WCDMA networks and GSM networks are still used today, and thus detailed descriptions thereof will be omitted.

The Internet service access device 120 extracts a string included in an outgoing signal from the user terminal 100 for wireless internet access received from the communication network 110 and corresponds to the extracted string (for example, flower delivery). The URL information is extracted and the user terminal 100 can be provided with the service from the corresponding information providing server 130 by using the extracted URL information. In addition, when the extracted string (for example, search * flower delivery) is for searching any information providing server 130 or a website, the Internet service access device 120 searches corresponding to the string. A list (eg, Gangnam Flower Delivery Website, 1004 Flower Delivery, etc.) may be provided to the user terminal 100.

The information providing server 130 is a device that provides various information (eg, document information, multimedia information, etc.) through a web browser provided in the user terminal 100.

Hereinafter, the configuration of the user terminal 100 according to the present invention will be described with reference to the drawings.

3 is a diagram schematically illustrating a configuration of a user terminal according to an exemplary embodiment of the present invention, and FIG. 4 is a diagram illustrating a method of displaying input information of a user terminal according to an exemplary embodiment of the present invention.

Referring to the configuration of the user terminal 100 according to the present invention with reference to FIG. 3, the user terminal 100 includes a key input unit 310, a storage unit 320, a display unit 330, a transceiver 340, and a controller ( 350).

Prior to describing each component of the user terminal 100, a schematic function of the user terminal 100 according to the present invention will be described. The user terminal 100 may include a predetermined specific key button of the key input unit 310. For example, when the '0' button, the '*' button, etc.) are operated (for example, a long press), the international call input mode is executed. The user interface screen according to the international call input mode includes a numeric string input area for inputting a telephone number according to an international call and a string input area for performing a wireless Internet service (see FIG. 4). In particular, the screen according to the international call input mode may be provided with a plurality of character input fields. For example, a plurality of character string input areas in which different character input modes, such as a Korean input window, an English input window, and a Chinese input window, are set may be provided. Of course, the character mode may be set according to the manipulation of a specific key (for example, a 'menu' button) of the key input unit 310 separately designated in one string input area, and thus, the user may use one string. After selecting the desired character mode in the input area, you can enter a text string.

In addition, the user terminal 100 according to the present invention may automatically set the character mode of the character string input area according to the international call input mode to correspond to the roamed country. For example, when the roamed country is an American, the character mode of the string input area may be English, and when the roamed country is China, the character mode may be automatically set without the user's separate operation in Chinese.

Accordingly, when the numeric string input area displayed on the display unit 330 of the user terminal 100 is selected (for example, the cursor is positioned), the user may input a number for an international call, and the key input unit 310 may be used. The character string input area may be selected by using a direction key of, to input a character string for wireless Internet service. When the international call input mode is executed, the information may be pre-specified to be input to any one of the numeric string input area and the string input area, or the information may be set to be input to the area where the international call input mode was previously executed. have. In addition, if it is located in the country, the initial string input area may be set, and if it is roamed overseas, the numeric string input area for international calls may be initially set.

Of course, in the typical user terminal 100, a number and a letter (Korean and / or English) correspond to one key button together. Therefore, when one key button is operated, the numbers and letters corresponding to each key button are simultaneously displayed. Input processing to the input area can be performed. For example, when a key button corresponding to the number "6" is operated, the user terminal 100 recognizes that the corresponding key button corresponds to the Korean letter "ㄷ" and the English letter "m", and the number corresponds to each input area. And characters can be input and displayed together (see FIG. 4). In addition, when numbers and characters are input processed together, when the input character is not a normal string, the string input area may be removed and only the numeric string input area may be displayed.

Subsequently, when a user inputs a number for an international call to the user terminal 100, the user may operate an first function button (for example, a call button) to perform an international call using the input number as a called number. If a character is input, the second function button (for example, an internet access button, etc.) may be operated to provide an internet access service corresponding to the input character string. Of course, since the input areas in which the numbers and letters are input are different, the user terminal 100 may provide a service according to the corresponding input area as one function button (for example, a 'confirmation' button) is input. . For example, a wireless Internet service may be provided when specific information is input only to a string input area, and an international call service may be provided when specific information is input only to a numeric string input area.

In addition, as a function button for performing a wireless Internet service after inputting a character string, an additional function key such as an mp3 function key or a camera function key may be applied. In particular, when the additional function key is used as a function button for wireless Internet access, content corresponding to the information corresponding to the additional function key (for example, music information in the case of the mp3 function key) can be provided as a wireless Internet service. . For example, when the user inputs the string “apple” using the user terminal 100 and then presses the mp3 function key, the user may be provided with a music file related to an apple.

Hereinafter, the components of the user terminal 100 will be described in detail. The key input unit 310 is an input means for receiving a telephone number for an international call, a string for internet access, and a command according to each function. Since the key input unit 310 may be obvious to those skilled in the art, detailed description thereof will be omitted.

The storage unit 320 stores information on numbers, letters, and the like corresponding to each key button of the key input unit 310. In addition, the storage unit 320 includes various information (eg, serial number of the terminal, communication protocol, etc.) necessary for performing each function (eg, voice / video call, Internet connection, etc.) of the user terminal 100. ) May be stored.

In particular, the storage unit 320 stores a connection path (for example, URL) as the Internet service access device 120 for accessing the Internet service access device 120. That is, when the user terminal 100 performs an internet connection using the input character string according to the present invention, the user terminal 100 uses the access path of the previously stored and set internet service access device 120 to the internet service access device 120. The character string connected and input through the communication network 110 is provided to the corresponding Internet service access device 120 to receive the corresponding Internet service. Here, if there are a plurality of Internet service access devices 120, the storage unit 320 may store access paths of the plurality of Internet service access devices 120. For example, when the Internet service access device 120 is provided in each country, the user terminal 100 recognizes the roamed country and corresponds to the roamed country by using a pre-stored access path such as URL. The wireless internet access service may be provided through the internet service access device 120.

The display unit 330 may be, for example, a liquid crystal, and the transceiver 340 is a communication means for the user terminal 100 to perform a function such as a call or an internet connection through the communication network 110.

The controller 350 controls the key input unit 310, the storage unit 320, the display unit 330, and the transceiver unit 340 so that the user terminal 100 executes the international call input mode. The control unit 350 may include a transmission / reception control unit 360, a screen display control unit 362, an input key recognition processing unit 364, a roaming processing unit 366, a call control unit 368, and an Internet service control unit 370. Of course, each component of the controller does not necessarily need to be implemented in hardware, and it is natural that it may be implemented in software.

As described above, the screen display control unit 362 of the user terminal 100 controls the display unit 330 to display a screen having a plurality of input areas so as to correspond to the international call input mode. That is, as shown in FIG. 4, the screen display control unit 362 may display the display unit 330 in a plurality of areas (eg, a first area 410 for displaying a number corresponding to an input key button). Second area 420 for displaying Korean characters or English letters corresponding to key buttons, and function button connection information display area 430 for requesting a service using information displayed in each area. Here, as described above, the character input area may be divided so that the Hangul area and the English letter area are distinguished from each other, but for convenience of description, the following description will be given with an example that there is one area for text input.

The input key recognition processor 364 recognizes a number and / or a letter corresponding to a key button input through the region where the cursor is currently located and the key input unit 310, and transmits the number and / or letters to the screen display control unit 362. For example, when the key button according to "6" is operated, if the first area 410 is currently selected (for example, when the cursor is located in the first area 410), the number "6" is entered. If the second area 420 is currently selected, the character “” or “m” according to the preset text mode is recognized and transferred to the screen display controller 362.

The screen display control unit 362 processes the numbers and / or letters recognized by the input key recognition processing unit 364 to be displayed in each area. As described above, the screen display control unit 362 displays the display unit 330 in a plurality of areas (eg, a numeric string input area, a Korean character input area, an English character input area, and function button connection information) according to the type of information to be displayed. It will be apparent that the data can be divided into three areas, but the following description will be given on the assumption that the data is divided into three areas.

The roaming processor 366 performs a function of providing a roaming service when the user terminal 100 roams abroad instead of a home country. Since international roaming is still in service, a detailed description of the roaming processor 366 will be omitted. However, the roaming processor 366 according to the present invention may recognize a language corresponding to the roamed country and transfer language information to the input key recognition processor 364. Accordingly, the input key recognition processor 364 may recognize a character input through the key input unit 310 to correspond to the language information received from the roaming processor 366. For example, when the user terminal 100 roams in the United States, the information input through the key input unit 310 may be recognized and processed in English characters.

The call controller 368 performs a function of connecting an international terminal with a called terminal through a communication network 110 and performing a voice / video call using the number input in the numeric string input area as a called number. Since it will be apparent to those skilled in the art that the user terminal 100 performs an international call service, a detailed description of the call controller 368 will be omitted.

The internet service controller 370 may include an input string switch unit 371, an internet access request signal generator 372, and a web browser driver 373. The Internet service control unit 370 is a function button (for example, an "OK" button, an "Internet connection" button) set in advance to correspond to the second area 420-4 after arbitrary key buttons are selected by the user. Etc.) is inputted to start an operation when an internet connection request is inputted.

The input string converting unit 371 switches the string displayed in the second area 420 when a function button preset for the character string switching is input from the user. For example, when the user sequentially inputs the key buttons corresponding to 6, 2, and 3 while the cursor is placed in the second area 410, the second area 420 may have a "Hangul" input mode. "Is displayed. However, when the character that the user intends to display in the second area 420 is an English letter, the user inputs a preset function button (for example, a # button, a volume button (see 440-FIG. 4), etc.) and the character mode. May be converted from Hangul to English characters, and accordingly, the second area may be converted to English characters and displayed. In this case, an English letter “mad” is displayed in the second region 420. In addition, when the user inputs an Internet connection request by inputting a function button corresponding to the character string displayed in the second area 420, the input string switching unit 371 checks whether the character string displayed in the second area 420 conforms to the grammar rule. If it does not meet the grammar rules, it can be automatically converted to a string in another language. For example, when the character string displayed in the second area 420 is "ㅅㄷ ㄱㅂ", the input string conversion unit 371 may automatically convert the character string into "trip". Of course, if the string converted by the automatic string conversion of the input string switching unit 371 also does not meet the grammar rules, an error message may be displayed on the display unit 330 or a dialog for confirming transmission may be displayed on the display unit 330. have.

When the internet access request signal generator 372 receives an internet access request using a character string displayed in the second area 420 and a corresponding function button from the user, the internet access request signal generator 372 generates transmission format data of a preset form using the character string. . The transmission format data according to the internet access request may include a URL (for example, 'http://go.k-merce.com/index') and an input character string, which is an access path for accessing the internet service access device 120. It may include. For example, when the input character string is "K-Phototel", the transmission format data may be "http://go.k-merce.com/index.asp?key=o&str=K-Phototel". The generated transmission format data is transmitted to the communication network 110 through the transceiver 340. As described above, when there are a plurality of Internet service access devices 120, the internet access request signal generation unit 372 may use the communication network 110 currently connected by using a connection path to each Internet service access device 120 stored in advance. Internet service access device 120 according to the country of roaming (consider roaming case). In addition, the Internet access request signal generation unit 372 may include the country information or language information for the currently roaming country country in the transmission format data.

The web browser driving unit 373 drives the web browser program stored in the storage unit 30 when an Internet connection request is input from the user.

4 illustrates a user terminal 100 displaying input information according to an exemplary embodiment of the present invention. The display unit 330 of the user terminal 100 illustrated in FIG. 4 is divided into three areas, and each area includes numeric information corresponding to an input key button, text information corresponding to an input key button, and each area. Function button connection information (eg, first area-call button, second area-confirmation button) for requesting a service using the information displayed on the screen is displayed. Of course, as described above, the number of regions may be further increased according to the type of information to be displayed on the display unit 330, and the information displayed on one region may be changed to any switching button (for example, a # button and a volume button ( 440, etc.) may be converted into information of other languages and displayed.

In particular, as shown in the drawing, the user terminal 100 is previously designated with a "+" symbol for an international call and displayed on the screen. Therefore, when a number is input in the first area and a function button (for example, a 'call' button) for performing a call is input, the input number to which the "+" symbol is added is used as a called number for an international call.

5 and 6 are conceptual views illustrating a process of performing a selection service using display information and a function button according to each preferred embodiment of the present invention.

Referring to FIG. 5, the display unit 330 of the user terminal 100 includes a first area (that is, a numeric string input area for inputting an international telephone number) and a second area (that is, a string input area for Internet access). ). If the information to be input is a phone number, the user selects a numeric string input area, and if a user wants to input a string, the user selects a string input area and inputs a corresponding number or letter. Of course, initially, any one of the numeric string input region and the string input region may be set in advance, and the user may select an input region to be input using the direction key button, the volume button 440, or the like. Thus, referring to FIG. 5, a user selects an input area to be input, inputs a number or a letter, and then operates a predetermined function button (for example, a 'confirmation' button) to make an international call according to the input string. Alternatively, wireless internet access may be performed according to the input string.

According to another exemplary embodiment, as described above, the user terminal 100 may display numbers and letters according to the operated key button without having to select an input area to be input by the user. Therefore, the display unit 330 of the user terminal 100 is divided into a plurality of areas, and different information is displayed together, and each area is set to correspond to each function button so that the user selects a function network. The information transmitted to 110 is changed, and the communication network 110 provides a service corresponding to the received information to the user terminal 100. That is, as shown in FIG. 6, the first area (that is, the numeric string input area) is set to correspond to the first function button (for example, a call button) so that when the user inputs the first function button, the user terminal 100 transmits request information for a voice call to the communication network 110. In addition, the second area (that is, the character string input area) is set to correspond to the second function button (for example, the confirmation button), and when the user inputs the second function button, the user terminal 100 is connected to the wireless Internet. The request information is transmitted to the communication network 110.

For convenience of explanation, hereinafter, it will be described on the assumption that the selection service method according to FIG. 5 is applied, and a schematic configuration of the Internet service access device 120 will be described below.

7 is a diagram schematically showing the configuration of the Internet service access device according to an embodiment of the present invention.

Each component illustrated in FIG. 7 may be implemented as an independent device, and the function of the search server 240 may be performed together in the proxy server 210.

Referring to FIG. 7, the apparatus 120 for accessing an Internet service according to the present invention includes a proxy server 210, a string DNS server 220, a general DNS server 230, and a search server 240.

The proxy server 210 is connection information (ie, a character string, a delimiter, an identifier, etc.) included in an outgoing signal (hereinafter referred to as an "Internet connection request signal") received from the user terminal 100, and the character string is a broad meaning. A delimiter and an identifier), and detailed URL information corresponding to the access information is transmitted to the user terminal 100. The proxy server 210 is configured to connect to the general DNS server 230 when connection information including domain name or URL information according to the related art is received. If an Internet connection request signal including a string not recognized by the general DNS server 230 is received, the string DNS server 220 or the search server 240 is configured to provide an Internet access service. Since the Internet access method using the general DNS server 230 according to the related art is well known to those skilled in the art, the description thereof will be omitted. The proxy server 210 may include a URL information extractor 250 and a URL information provider 255. The URL information providing unit 255 transmits the URL information of the site corresponding to the access information to the user terminal 100 as a method of providing an Internet access service, and allows the user terminal 100 to access the corresponding URL. The provider 255 may call a page corresponding to the URL information and transmit the corresponding page to the user terminal 100. That is, in the Internet access service according to the present invention, when the proxy server 210 extracts the detailed URL information and transmits the detailed URL information to the user terminal 100, the user terminal 100 is configured to reconnect to the corresponding URL or corresponds to the corresponding URL. It can be configured to call the page to provide directly to the user terminal 100. Here, since the provided page information includes a corresponding URL, the information transmitted from the proxy server 210 to the user terminal 100 will be referred to as URL information.

The URL information extraction unit 250 performs a function of extracting detailed URL information corresponding to the access information, and is configured to analyze the access information (ie, a character string) and provide detailed URL information according to a preset method. The URL information extracting unit 250 determines whether the access information is a signal to access a specific site or a request for a search list by using the structure of the access information, and provides an Internet access service corresponding to the determination result. can do. In Table 1 below, an embodiment of a method of determining whether the access information is a site access request signal, a search list request signal, or a sequential request signal by analyzing the structure of the access information is analyzed by the URL information extractor 250. .

division rescue action Site access request signal Consists of strings only such as ulzzang photos, actors Request a string DNS server to extract URL information for a site that corresponds to a string Search list request signal Delimiter and multiple strings, such as search * flower delivery and ticketing * movies Recognizes the preceding string as a service type and requests the search server to extract the following string and the search list corresponding to that service type. Sequential Request Signal * Consists of delimiter and one string such as Chinese house After performing the operation by recognizing it as the site access request signal first, if the corresponding URL information does not exist, the operation is recognized by the search list request signal.

The URL information extracting unit 250 determines whether the access information is a site access request signal, a search list request signal, or a sequential request signal by using the structure of the access information. At this time, it is obvious that the access information may further include a separate identifier (eg,! Or #) for indicating that the site access request signal or the search list request signal. However, hereinafter, as described above, the type of the access information is determined only by the structure of the access information, and the access information will be described based on the case of the site access request signal or search list request signal.

For example, when the user wants to access the "K-freetel", the user terminal 100 converts the string "K-freetel" input by the user into the predetermined transmission format data to recognize the communication network 110 Transmission to the communication network 110. In this case, the character string may be converted into and included in the transmission format data in the form of connection information such as, for example, http: // K-freetel, * K-freetel, and http: // * K-freetel. The proxy server 210 analyzes the structure of the connection information included in the received transmission format data, recognizes that the connection information is a site connection request signal, and transmits the connection information to the string DNS server 220. The string DNS server 220 extracts a domain address (for example, http://www.ktf.com) corresponding to the access information and provides it to the proxy server 210. The proxy server 210 transmits the received domain address to the user terminal 100 to access the site or transmits a web page corresponding to the domain address to the user terminal 100.

Next, when the access information included in the transmission format data is "search * flower delivery", the proxy server 210 receives the domain address of the site for site search from the string DNS server 220 to the search server 240. Pass the search request. The search server 240 searches for corresponding site information and transmits a search list to the proxy server 210, and the proxy server 210 transmits the received search list to the user terminal 100. Of course, if the domain addresses received from the string DNS server 220 are information corresponding to the search list (for example, the connection information is "movie * reservation" and the received domain addresses are domains of sites that provide a movie reservation service). In the case of addresses), the received domain addresses may be transmitted to the user terminal 100. In addition, when only one search result included in the search list or a site for performing a corresponding service is designated in advance, the search site may be directly connected to the corresponding site.

In addition, when the access information includes country information or language information of the corresponding country, the proxy server 210 provides URL information corresponding to the corresponding country or language to the user terminal 100. For example, if the country information included in the access information is the United States and the search list request signal, URL information (eg, www.google.com) of a site providing a search service of the United States is transmitted to the user terminal 100. to provide. Of course, the proxy server 210 may include direct information (for example, the name of 'Google') of the search server 240 in the access information, that is, not the country information (ie, each country in the user terminal 100). If the information on the search server 240 according to the pre-set), the URL information of the corresponding site may be provided.

When the access information received from the proxy server 210 is a site access request signal, the string DNS server 220 extracts and transfers a domain address (ie, URL information) corresponding to the access information to the proxy server 210. When the access information is a search list request signal, a domain address corresponding to a service type and / or a search word is extracted and provided to the proxy server 210. For example, if the search list request signal is "search * flower delivery", the domain address (for example, www.yahoo.co.kr) of the site providing the search service is extracted and transmitted to the proxy server 210. Can be. It is natural that a string can contain a number.

As shown in FIG. 2, the string DNS server 220 may include a code analyzer 260 and an address register 265, and may further include a storage unit for storing domain addresses. The code analyzing unit 260 is configured to extract the URL information by referring to the address registration unit 265 with the received string information. The address registration unit 265 configures, stores, and manages a mapping table of access information and domain addresses.

Although not shown in FIG. 2, the communication network 110 may include a location recognition server for performing a location based service. The location recognition server recognizes the location information of the user terminal 100 by using the location information of the user terminal 100 received through the base station or the GPS location data received from the user terminal 100 to connect to the Internet service access device ( 120). In this case, the Internet service access device 120 may provide location-based information corresponding to a character string included in an outgoing signal received from the user terminal 100. For example, when the character string included in the outgoing signal is "reservation * movie * shiri", the Internet service access device 120 provides a reservation service, and a movie is included in the subject of the reservation service, and the movie name "Shri" is screened. Only a website including a movie theater corresponding to the location of the user terminal 100 can be extracted and provided to the user terminal 100 as a search list. Of course, if there is only one website that provides the service or there is a website designated in advance for the movie booking service, the website may be immediately accessed. In providing the location-based service, the location range corresponding to the location of the user terminal 100 may be an attempt range on the administrative district.
