Best Modes for carrying out the Invention Hereinafter, preferred embodiments of the present invention will be described in 15 more detail with reference to the accompanying drawings.

Fig. 2A represents the construction of the mobile terminal according to the present invention.

The service that a user wants to use can be provided with the operation of just one button. Accordingly, the mobile terminal according to the present invention has a 20 character input mode conversion button for converting a number input mode to character input mode, a call request button for requesting a call, a button for connecting with the internet and the like. A keypad generates pecuniary signals in accordance with the operation of these buttons. The mobile terminal according to the present invention recognizes these signals and conducts service such as call service, internet service, search 5 service and the like in accordance with these signals. Hereinafter, these services will be indicated by one-button service.

Referring to Fig. 2A, the mobile terminal according to the present invention comprises search word input module 210, call module 220, web browser module 230, and search module 240.

10 Furthermore, the search word input module 210 comprises a number input layer module 213 and character input layer module 217. Generally, a conventional mobile terminal is set up for a number input mode, so the user has to operate buttons multiple times to select the menu which a character can be inputted when the user wants to input characters. However, according to the present invention, the operation of one button 15 using a predetermined character input mode conversion button allows the input mode to be converted to the character input mode. The character input mode conversion button is an independent function button which is used to conduct the conversion of input mode in accordance with operating the button one time only, and it can be implemented using"*" button or"#"button which is set up so that conversion of the character input mode may 20 occur. As described above, the mobile terminal can be connected with the mobile terminal of a receiver or website after the user inputs a search word and operates the button one time.

The call module 220 sends a call to the mobile terminal of the receiver in accordance with the search word. The call module 220 tries to connect with the mobile 5 terminal of receiver in accordance with the search word after the user inputs a search word and presses a"send"button. Accordingly, the call module 220 tries to connect with the mobile terminal of a receiver using a number if the search word is a number, but tries to connect with the mobile terminal of a receiver using the phone number in accordance with the search word extracted from the list in the mobile terminal by the search module 10 240 if the search word is a character. That is, the search module 240 searches whether the name of the receiver is the same as the inputted search word in the list, and then extracts the phone number in accordance with the name of the receiver that is the same as the inputted search word if it exists.

The web browser module 230 connects with a website in accordance with the search 15 word. The web browser module 230 requests the website in accordance with the search word connection after the user inputs the search word and presses the button for internet connection. If the search word is URL, the web browser module 230 tries to connect with the predetermined website in accordance with the URL. In contrast if the search word is number or character except URL, the web browser module 230 tries to connect with the 20 website in accordance with the search word using an IP address in accordance with the search word.

Connection with website according to the present invention occurs with the operation of one button. However the prior art is generally inconvenient since the user has to connect with the internet, input the URL of website, and also click the button for 5 checking. In contrast according to the present invention, if the user inputs a search word in accordance with the IP address of website and presses the button for internet connection, then the mobile terminal can connect with the website using a DNS server in which IP address in accordance with the search word is stored. According to the present invention, an internet connection request signal may comprise an identifier so that a 10 proxy server connected with the DNS server does not transmit the search word to a typical DNS server but rather to the DNS server according to the present. invention.

Hereinafter, the identifier will be indicated as"connection identifier".

Also, the present invention can provide service for searching according to the present invention as well as service for call and internet connection. That is, the results of 15 a search based on location in accordance with the search word can be provided to the mobile terminal if the search word is made up of characters. The service for searching can be conducted in a separate search server. The one-button service according to the present invention comprises service for a call, internet, and search. The service for internet and search will be indicated as"data service".

20 Fig. 2B is a flowchart representing the procedure for providing one-button service according to a preferred embodiment of the present invention.

According to the present invention, the user can input a character conveniently by conversion to the character mode and connect with a desired website in one click after the 5 user inputs a character as voice call. Also, the user can connect with a desired website via search word by one-button operation after the user inputs the search word such as a predetermined phone number, a number, and the like to avoid all complication of inputting a URL. Also, the present invention can provide service for a search based on the location.

10 Upon referring to Fig. 2B, the procedure for providing one-button service according to the present invention will be described.

In step S250 the user can input a search word according to the classification of the search word to be inputted. According to the present invention, the number input mode is established for the mobile terminal. Therefore in step 265 the user can input a number 15 without operating a button if the user inputs a number. If the user inputs a character, the user presses the character input mode conversion button to convert from input mode of the mobile terminal to character input mode in step S260, so that the user can input character. The mobile terminal according to the present invention may have an independent function button to execute conversion of character input mode by operating 20 the button one time. For example, the independent function button can be"*"button or "#"button established for conversion of the character input mode. If the user presses the button at a predetermined time, the input mode of the mobile terminal is converted to character input mode.

In step S270 the user clicks the button to select the desired service. One-button 5 service according to the present invention can provide a service to search based on the location, as well as a service for call and internet connection.

In step S275 the mobile terminal extracts a phone number in accordance with the search word in the list stored in the mobile terminal and requests a call connection to the phone number if the button is a call button.

10 In step S280 the mobile terminal requests internet connection if the button is an internet connection button. As such, the search word may include a predetermined number in accordance with IP address, phone number, character, and the like. Therefore, the internet request signal may include a separate identifier different from a typical internet request signal. The DNS server according to the present invention extracts an IP 15 address based on the search word if the button is the internet connection button. The proxy server can transmit the internet request signal to the DNS server in which the IP address based on the search word is stored due to the connection identifier included in the internet request signal. The DNS server judges whether the IP address based on the search word exists by referring to the database. While the conventional DNS server extracts only 20 an IP address in accordance with a URL, the DNS server according to the present invention can extract an IP address according to number, phone number, Korean URL, and the like.

If the IP address based on the search word exists, the mobile terminal can connect with website in accordance with the IP address, as shown in step S285.

5 To the contrary if the IP address in accordance with the search word doesn't exist, the mobile terminal can provide a service to search based on location in accordance with the search word in step S290. That is, the search server according to the present invention can provide the results of a search to the mobile terminal after conducting the search in accordance with the search word. The search server provides only results in accordance 10 with location information of the mobile terminal.

Therefore, according to the present invention, the user can connect with the internet using one button conveniently, and provide service for a search based on location if a website in accordance with the search word doesn't exist.

Hereinafter, a data service of one-button service will be described. A procedure for 15 providing Internet connection service of one-button service will be described in the description of the first embodiment. Thereafter, the procedure for providing search service for one-button service will be described in the description of the second embodiment. Accordingly, the first embodiment and the second embodiment according to the present invention will be described in detail.

Referring to Fig. 3 the one-button internet connection system according to the present invention comprises a mobile terminal 200, a base terminal 300, abase terminal controller 305, a connection network 310, DNS server 350, and multiple websites. The system may further comprise a proxy server 340.

In more detail, the connection network 310 includes PSTN 320 and packet connection network 330. The mobile terminal 200 connects with DNS server through any one of the connection networks 310. The PSTN 320 includes mobile switching center (MSC) 322 and inter working function (IWF) 324, and the packet connection network 330 includes PCF 332 and PDSN 334.

The mobile terminal 200 transmits an internet connection request signal including the search word inputted by the user to the DNS server 350. The internet connection request signal can be transmitted to the DNS server 350 through the proxy server 340.

The internet connection according to the present invention is different from the typical user connecting with the website after connecting with the internet network, because the user directly connects with the website. Therefore, the proxy server 340 can recognize and transmit the search word to the predetermined DNS 350.

Additionally, the search word in the internet connection request signal may include a separate connection identifier. The search word includes a URL (Uniform Resource Locater) in accordance with the IP address of a website 360, number, phone number and the like, and the website 360 includes the first website to the Nth website 360-1,..., 360-N.

5 The mobile terminal 200 transmits the internet connection request signal including the search word or the connection identifier to the DNS server 350 through the base terminal 300, the base terminal controller 305, and the connection network 310. The mobile terminal 200 transmits the internet connection request signal to the DNS server 350 through the mobile switching center (MSC) 322 and the inter-working function 10 (IWF) 324 when the connection network 310 is the PSTN, but transmits the internet connection request signal to the DNS server 350 through the PCF 332 and the PDSN 334 when the connection network 310 is the packet connection network 330. Further, the inter-working function (IWF) 324 and the PDSN 334 convert the protocol of wireless network to internet protocol, so that they connect the wireless network with the internet 15 network. That is, the inter-working function (IWF) 324 and the PDSN 334 connect the mobile terminal 200 with the internet network.

The internet request signal according to the present invention must be transmitted to the DNS server 350 that can recognize the search word. Therefore, a separate connection identifier is required so that the internet request signal may be transmitted to the DNS 350 20 when a separate DNS server 350 is established. Accordingly, the proxy server 340 which can recognize the connection identifier will be included in the system.

Also, the proxy server 340 can recognize the connection identifier included in the internet connection request signal and transmit the search word to the DNS server 350.

Finally, the DNS server 350 extracts the IP address based on the search word transmitted 5 from the proxy server 340 and transmits the IP address to the mobile terminal 200. The mobile terminal 200 can connect with the website in accordance with the IP address using the IP address transmitted from the DNS server 350. Thus the DNS server 350 can extract the IP address based on the search word by referring to the IP address information database 355 connected with the DNS server 350 (See Fig. 4B).

10 Fig. 4A is a flowchart representing the procedure for conducting one-button internet connection service according to the present invention.

Upon referring to Fig. 4A, this procedure will be described in detail.

In step S415 the mobile terminal 200 transmits the connection request signal to the proxy server 340.

20 For example, if the user of the mobile terminal 200 inputs the number"92446"on the screen of the mobile terminal and then inputs wireless web browser execution key, the mobile terminal 200 generates the website connection request signal of"http: \\ 92446"by combining the connection identifier"*"to"92446".

In step S415 if the generated connection request signal is transmitted to the proxy 5 server 340, then in step S420 the proxy server 340 recognizes it as the website connection request signal generated by connection identifier"*"and transmits the search word to the DNS server 350.

In step S430 the DNS server 350 extracts the IP address in accordance with the search word by mapping the IP address information database 355 and transmits the IP 10 address to the mobile terminal in step S435.

In step S440 if the mobile terminal connects with the website based on an IP address using the IP address, then as shown in step S445, the website transmits the contents of the website to the mobile terminal and the mobile terminal displays the contents of the website.

15 Fig. 4B represents a map table stored in an IP information database according to the present invention.

The map table stored in the IP address information database comprises a URL field 402, number field 404, phone number field 406, and IP address field 408 as shown in Fig.

Referring to Fig. 6, the device for providing service for a search according to the second embodiment further comprises location providing server 600 and search server 370.

The location providing server 600 connects with mobile switching center (MSC) 322 or PCF 332 and stores the location coordinate in which the mobile terminal 200 sends a call. That is, the location providing server 600 stores the base terminal identifier generated by the mobile terminal 200 as the location coordinate and transmits the location coordinate that stores the base terminal identifier to the service server in accordance with request of the service server.

5 The data service server 390 relays data service request transmitted from the mobile terminal 200. According to the present invention, the data service in accordance with the character inputted into the mobile terminal 200 is provided. The data service server 390 comprises the DNS server 350 and the search server 370.

Furthermore, the search server 370 outputs the results based on the location 10 coordinate of the mobile terminal 200 and the inputted search word. For example, if the character is'hospital'and the location in which the call is sent from the mobile terminal 200 is'Kang Nam terminal', then information about hospitals located around Kang Nam terminal is displayed as output.

The DNS server 350 outputs the IP address in accordance with the inputted search 15 word such as a domain by character. For example, if'KTF'is inputted into the mobile terminal 200 by character and then transmitted to the DNS server 350, the DNS server 350 can extract the domain address of the website,'http : //www. ktf. com', and IP address in accordance with the domain address.

Other configurations are the same as or similar to that of the first embodiment, so 20 their descriptions will be omitted. Also, according to the second embodiment, the proxy server 340, which transmits the search word to the data service server 390, can be comprised as an additional feature. However, the description of the connection identifier and the proxy server 340 will be omitted to simplify the description of the present invention.

5 When the user operates the character input mode conversion button on the mobile terminal 200, the input mode of the mobile terminal 200 is converted to the character input mode so the user can input a character as the search word. The search word may be the name of the receiver (for example, index number, name, phone number, etc. ) of the list of phone numbers stored in the mobile terminal 200, domain, other search words and 10 the like.

After the user inputs the search word, the service via the user operating the call request button or data service request button on the mobile terminal 200 is provided. For example, the user inputs the name of the receiver in a character and then operates the call request button; the mobile terminal 200 searches the phone number in accordance with 15 the name of the receiver in the list and sends a call for the phone number. Also, if the user inputs a character such as a domain and then operates the data service request button, the mobile terminal 200 outputs results of the search in accordance with the search word or connects with the website in accordance with the search word.

Accordingly, call connection service can be provided by using only the mobile 20 terminal 200 if the search word is a name recognized within the mobile terminal of

receiver. However, if the requested service is data service, other processing devicees are required to provide the data service. The other processing devicees may include the data service server 390, the search server 370, and the DNS server 350. Additionally, other processing devicees will conduct data service including the internet since they are connected through the inter-working function 324.

The search word is transmitted to the data service server 390 when the user operates the data service request button.

The user can request an internet connection service or search service with the operation of one button only one time by including the internet connection request button and search request button.

Also, the data service server 390 may process the search word without judging the service request based on the search word inputted by the user that comes under either the internet connection service or the search service. In this situation, a determination occurs by the mapped result of the DNS 350.

That is, if the search word is transmitted from the mobile terminal 200 to the data service server 390, the data service server 390 transmits it to the DNS server 350 and determines whether the IP address in accordance with the search word exists. If the data service server 390 receives the IP address from the DNS server 350, the data service server 390 establishes the connection between the websites in accordance with the mobile terminal 200 and the IP address.

To the contrary if the data service server 390 doesn't receive IP address from the DNS server 350, the data service server 390 can provide search service in accordance with the received search word. At this time, the data service server 390 recognizes the location of the mobile terminal 200 and conducts a search using the character inputted 5 and location information of the mobile terminal 200. More specifically, the data service server 390 requests the location information of the mobile terminal 200 of the location providing server 600 connected with the mobile switching center 322. The data service server 390 receives the base terminal identifier according to the base terminal in which the mobile terminal 200 sends a call (i. e. , the call includes real voice call and data service 10 request) from the location providing server 600 in the format of the location coordinate.

Therefore, the data service server 390 transmits the character and the location coordinate of the mobile terminal 200 to the search server 370 and requests a search. Then, the data service server 390 receives the results of the search from the search server 370 and transmits them to the mobile terminal 200. That is, the search service related solely 15 on the character can be used quite efficiently if the character has a meaning related very closely with the location.

For example, if the user inputs'gas terminal'or'hospital'as the search word, the user can search for gas terminals and hospitals located within the closest distance from the location of the mobile terminal 200.

20 The method for providing one-button service will be described when the internet connection service request button and search service request button are implemented as one button by integrating the two buttons. However, the present invention is not limited to this embodiment, since two buttons can still be provided as the internet connection service request button and search service request button respectively.

5 Fig. 7 is a flowchart representing a procedure for providing data service according to a preferred embodiment of the present invention. The procedure of the steps shown in Fig. 7 will be described in detail.

In step S700, the search word inputted into the mobile terminal 200 is transmitted to 10 the data service server 390. In step 705, the data service server 390 transmits the search word to the DNS server 350 and requests the DNS server 350 IP address in accordance with the search word. In step 710, the DNS server 350 receives the search results of the IP address from the DNS server 350.

In the step 715, the data service server 390 checks if IP address is in the search 15 results, so that the data service server 390 determines whether the IP address in accordance with the search word exists. If the IP address is in the search results, the search word is mapped to the IP address and goes to the step S720. If the IP address is not in the search results, the data service server 390 recognizes it as search service and goes to the step S735.

20 In the step 720, if the IP address in accordance with the search word exists, the data service server 390 transmits the IP address to the mobile terminal 200. In the step 725, the mobile terminal 200 requests connection with a website in accordance with the IP address.

If the mobile terminal 200 receives a connection answer signal from the website, connection between the mobile terminal 200 and website is established in the step 730.

5 In the step 735, if the search word is for search service, the data service server 390 requests the location providing server 600 the location coordinate of the mobile terminal 200 using the identifier of the mobile terminal 200 (for example, the phone number of subscriber set up in the mobile terminal 200).

In the step 740, the data service server 390 receives the location coordinate of the 10 mobile terminal 200 from the location providing server 600. The location coordinate includes the identifier of the base terminal that the mobile terminal 200 sends a call to.

In the step 745, the data service server 390 transmits the search word and the location coordinate of the mobile terminal 200 to the search server 370 and requests a search regarding the search word of the search server 370.

15 In the step 750, the data service server 390 receives the search results from the search server 370 using the search word and the location coordinate of the mobile terminal 200.

In the step 755, the data service server 390 transmits the search results to the mobile terminal 200.

20 Fig. 8A is a flowchart representing a procedure for providing call service according to a preferred embodiment of the present invention.

The procedure of the steps shown in Fig. 8A is described in detail as follows.

In the step S810, the user of the mobile terminal 200 operates a character input 5 mode conversion button. The mobile terminal 200 generates a character input mode conversion signal in accordance with the character input mode conversion button, and a character input layer program is executed in accordance with the character input mode conversion signal.

The character input mode conversion button can be mounted on the mobile terminal 10 200. Also, it may be possible that the character input mode is converted using another button on the mobile terminal 200. For example, the character input mode conversion signal can be generated by the user pressing the pound sign"&num "button on the mobile terminal 200 for a predetermined time.

In step 813, the mobile terminal 200 executes the character input layer program.

15 That is, the character input layer program outputs the screen of character input mode in accordance with the character input mode conversion signal on the display of the mobile terminal 200 and allows the user to interface to input a character.

In the step S815, the mobile terminal 200 that was converted to the character input mode inputs the search word of the user. In more detail, the search word is for searching 20 the name of the receiver stored in the list of the mobile terminal 200 in advance. For example, let us suppose that a man"Hong Gil Dong", who is the receiver, and "02-565-6727", which is the phone number of the receiver, are stored in the list. The user inputs this name"Hong Gil Dong"as the search word.

In the step S820, the user inputs a call disconnection request button after the user 5 inputs the search word. The mobile terminal 200 generates a call request signal in accordance with the operation of the call request button and extracts the call request signal.

In the step S825, the mobile terminal 200 searches the name of the receiver as the search word previously inputted in the step S815 in the list in accordance with the call 10 request signal extracted in the step S820. That is, as the example of the step S815, if the search word (s) inputted is"Hong Gil Dong", the related the search results will be "02-565-6727".

In the step S830, the mobile terminal 200 sends a call using the phone number searched in the step S825. That is, the mobile terminal 200 makes the call using the 15 phone number in accordance with the name of the receiver searched by the user.

Otherwise, in the step 835, the call is disconnected in accordance with the call disconnection request inputted by the user in the step 835.

Fig. 8B is a flowchart representing a procedure for providing the service in a mobile 20 terminal when the service requested according to a preferred embodiment of the present invention is data service.

The procedure of the steps shown in Fig. 8A will be described in detail as follows.

In the step S850, the user of the mobile terminal 200 inputs a character input mode conversion button. The mobile terminal 200 generates a character input mode conversion 5 signal in accordance with the character input mode conversion button, and a character input layer program is executed in accordance with the character input mode conversion signal.

In step S853, the mobile terminal 200 executes the character input layer program.

That is, the character input layer program outputs the screen for the character input mode 10 in accordance with the character input mode conversion signal on the display of the mobile terminal 200 and allows the user to interface to input a character.

In the step S855, the mobile terminal 200 that was converted to the character input mode inputs the search word of the user. The search word is for searching desired information or may be a domain, number or code in accordance with the search service 15 for searching the desired information and desired website. For example, the search word can be a generic keyword to search such as"hospital", "gas terminal","Chinese restaurant", "cinema", etc. Also, the keyword can be a well-known Korean domain address of an internet site such as"daum","Korea Telecom", "KTF"and the like.

In the step S860, the user inputs the data service request button after the user inputs 20 the search word. The mobile terminal 200 generates a data service request signal and extracts it in accordance with the operation of the data service request button and recognizes this data service request signal.

In the step S865, the mobile terminal 200 executes the web browser in accordance with the data service request signal. In the step 870, the mobile terminal 200 receives the 5 contents of the website or the search results in accordance with the search word inputted, and outputs those results using the web browser.

For example, if the search word is"hospital", information of hospitals located in the region where the mobile terminal 200 is located will be outputted; if the search word is "KTF", contents of that website will be outputted after the mobile terminal 200 10 connects with the website.

Finally, in the step S880, the data service is disconnected in accordance with the service disconnection request inputted by the user.

Fig. 9 is a flowchart representing a procedure for providing service in a data service 15 server in accordance with the search word transmitted from the mobile terminal 200 according to a preferred embodiment of the present invention. Hereinafter, the procedure of the steps shown in Fig. 8A will be described in detail.

In the step S910, the data service server 390 receives the search word from the mobile terminal 200. The mobile terminal 200 transmits the search word when the user 20 inputs the search word in the character input mode of the mobile terminal 200 and operates the data service request button to send the signal.

In the step S915, the data service server 390 requests an IP address in accordance with the search word using the search word just received. At that time, the DNS server 350 searches whether an IP address based on the search word exists. For example, the 5 DNS server 350 searches the website address and the IP address in accordance with "KTF"when the search word is"KTF". Thereafter, the DNS server 350 transmits a failed search message to the data service server if the IP address in accordance with the search word doesn't exist.

In the step S920, the data service server 390 determines whether the IP address in 10 accordance with the search word exists using the search results of the IP address transmitted from the DNS server 350. In the step S920, the data service server 390 transmits the IP address to the mobile terminal 200 if the IP address is in the search results of IP address. Although the procedure in the mobile terminal 200 is omitted, the mobile terminal 200 that has received the IP address establishes the connection with the IP 15 address through the web browser.

Finally, in the step 920, the search service using the search word is provided if the search results of the IP address that don't include an IP address (i. e. if the search fail message is transmitted).

In the step 940, the data service server 390 requests the location coordinate of the 20 mobile terminal 200 of the location providing server 600 to receive the location coordinate of the mobile terminal 200 to be added to the search word.

In the step 945, the data service server 390 receives the location coordinate of the mobile terminal 200 from the location providing server 600. The location providing server 600 connects with the mobile switching center and the like for the purpose of storing the location information of the mobile terminal 200. The location providing server 5 600 can be HLR (Home Location Register), VLR (Visitor Location Register) and the like.

This location providing server 600 stores the base terminal identifier of the base terminal which the mobile terminal sends the call to as the location of the mobile terminal 200 and then transmits the location coordinate of the mobile terminal 200 in accordance with the request of the data service server 390 and the like.

10 In the steps S940 and S945, the location coordinate of the mobile terminal 200 may include the base terminal identifier of the base terminal that receives the call connection signal from the mobile terminal 200. However, in the near future, the mobile terminal will likely include the function that can receive the location coordinate from GPS (Global Positioning System) satellites directly. Therefore, on this assumption, those skilled in the 15 art will recognize that the steps S940 and S945 can be omitted, and the location coordinate can be transmitted directly from the mobile terminal 200.

In the step S950, the data service server 390 transmits the search word and the location coordinate of the mobile terminal 200 to the search server 370. The search function is a primary function of the search server 370. The search server 370 according 20 to the search function organizes the information in accordance with the location based on a divided location to a predetermined area and furthermore outputs information according to the location and the search word.

In the step S955, the data service server 390 receives the search results based on the search word and the location coordinate from the search server 370, and transmits the 5 search results to the mobile terminal 200 in the step S960. The search server 370 is for conducting an LBS (Location Based Services) function, and since the technology about the LBS is well known to those skilled in the art further description will be omitted. In the present invention, the search server 370 receives the search word and the location information and transmits the search results of the information to other servers and clients 10 requesting a search of the information.

In the step S970, the data service server 390 receives the disconnection request from the mobile terminal 200 in accordance with the disconnection request from the user and disconnects with the mobile terminal 200.

15 Fig. 10A is a screen representing a procedure for providing call service according to a preferred embodiment of the present invention.

Referring to Fig. 10A, the mobile terminal has various buttons such as a call request button 1010, a data service request button 1020, and a character input mode conversion button 1000. These buttons are merely indicated according to one of the embodiments, 20 but they can be readily modified by those skilled in the art. Hereinafter, another embodiment regarding call service will be described.

The mobile terminal 200 converts the input mode of the mobile terminal 200 to the character input mode when the user operates the character input mode conversion button 1000 in order to input the search word. Accordingly, the character input mode conversion 5 button 1000 can be a button set up for the character input mode conversion function. Also it is possible that the function of the character input mode conversion is executed when a standard button like the pound button (i. e.,"#"sign button) is pressed for predetermined time.

The mobile terminal 200 searches the search word inputted in the list storing the 10 names of the receiver when the user inputs the search word in the character input mode and operates the call connection button 1010.

For an example, let us suppose that the name of the receiver is a man"Hong Gil Dong"and his phone number is"02-610-6727". If the user inputs"Hong Gil Dong"in the input mode and presses the call request button 1010, then the mobile terminal 200 15 searches for the name of the receiver stored in the list in advance using the search word "Hong Gil Dong". Thereafter, the mobile terminal 200 finds"Hong Gil Dong"in the list, and initiates a call using the phone number"02-610-6727". The screen showing the results in accordance with this call procedure is displayed on the mobile terminal 200.

20 Fig. 10B is a screen representing a procedure for providing internet connection service according to a preferred embodiment of the present invention.

Referring to Fig. 10B, the mobile terminal 200 has a call request button 1010, data service request button 1020, and character input mode conversion button 1000, the same as shown in Fig. 10A.

5 The user operates the character input mode conversion button 1000 and inputs a search word in the character input mode by operating the button 100 when the user intends to use data service (for an example, internet connection website).

As shown in Fig 10B, the user requests connection with the internet website of the Korean domain"daum". The screen showing the results 1045 is displayed on the mobile 10 terminal 200 if the user inputs"daum"in the character input mode of the mobile terminal 200 and operates the data service request button 1020.

The procedure for displaying the screen of results 1045 in accordance with the operation of the button and the input of the search word will be described in detail. The mobile terminal 200 transmits the search word inputted in accordance with the operation 15 of the data service request button 1020 to the data service server 390.

The data service server 390 transmits the search word to the DNS server 350 and requests a search. The DNS server 350 extracts the IP address in accordance with the search word"daum"and transmits it to the data service server 390.

The data service server 390 transmits the IP address to the mobile terminal 200. The 20 mobile terminal 200 requests a connection with a website in accordance with the IP address and displays the screen of results 1045 when the response to the request from the website is received and the connection is established.

The screen of results 1045 is the screen displayed when the mobile terminal 200 connects with IP address using the web browser.

5 Fig. 10C is a screen representing a procedure for providing search service according to a preferred embodiment of the present invention.

Referring to Fig. 10C, the mobile terminal 200 has a call request button 1010, data service request button 1020, and character input mode conversion button 1000, the same 10 as Fig. 10A.

The user operates the character input mode conversion button 1000 and inputs a search word in the character input mode when the user intends to use data service (for example, search service).

As shown in Fig. 10C, the user inputs the search word"Chinese restaurant"and 15 conducts a search. The screen of search results 1055 is displayed on the mobile terminal 200 after the user inputs"Chinese restaurant"in the character input mode of the mobile terminal 200 and operates the data service request button 1020.

The procedure in displaying the screen of results 1045 in accordance with the operation of the button and input of the search word will be described in detail. The 20 mobile terminal 200 transmits the search word inputted in accordance with the operation of the data service request button 1020 to the data service server 390.

Thereafter, the data service server 390 transmits the search word to the DNS server 350 and requests a search to occur. The DNS server 350 searches the IP address in accordance with the search word"Chinese restaurant"but transmits search fail message 5 to the data service server 390.

The data service server 390 recognizes the requested service as a search service using the search fail message transmitted from the DNS server 350. The data service server 390 requests the location providing server 370 for the location coordinate of the mobile terminal 200 to transmit the location coordinate of the mobile terminal 200 and 10 the search word"Chinese restaurant"since the search function according to the present invention is based on the location.

The location providing server 600 transmits the base terminal identifier of the area and the mobile terminal 200 sends a call to the location coordinate in accordance with the request to data service server 390. For example, if the location coordinate is"Yoek Sam 1 15 Dong", the data service server 390 transmits the location coordinate"Yoek Sam 1 Dong" and the search word"Chinese restaurant" (1050) to the search server 370. Then the search server 370 conducts a search and transmits the search results to the data service server 390.

The data service server 390 transmits the search results to the mobile terminal 200, 20 and the mobile terminal 200 displays the search results.

However, the request for the location coordinate can be omitted if the mobile terminal 200 already includes the function to receive the location coordinate from GPS satellites. That is, the data service server 390 can directly receive the location coordinate of the mobile terminal 200 from the mobile terminal 200 if the mobile terminal 200 5 includes the function to receive the location coordinate from GPS satellites.

Although the invention has been described in its preferred form with a certain degree of particularity, it is understood that the present disclosure of the preferred form can be changed in various details of construction so that the combination and arrangement of parts may be implemented without departing from the spirit and the scope of the 10 invention as hereinafter claimed.
