METHOD AND DEVICE FOR PROVIDING ONE BUTTON-SERVICE IN

MOBILE TERMINAL

Technical Field

The present invention relates to a method and device for providing one-button

service in mobile terminal and more specifically, relates to a method and device for

providing phone service, internet service, and search service by pressing only one button.

That is the present invention can provide these services by inputting a search word and

pressing one button.

In other words, the present invention relates to a method and device that can

provide data service conveniently like conventional voice calling since a user not only

can connect to a website by inputting numbers, codes and the like and then pressing one

button, but the user can also input characters conveniently by operating one button.

Therefore, according to the present invention, the mode of the mobile terminal is

converted to a character input mode in accordance with the user's operation of the input

mode conversion button mounted on the mobile terminal. In this mode, if the user inputs

characters and operates the call request button or data service button, the mobile terminal

conducts voice calling, connection with web server and location based services (LBS) in

accordance with the operation of the button. Background Art

As data communication technology has developed, a super high speed internet has

been established, allowing more and more users to become internet friendly by using the

internet. This internet includes free and fee-based websites that provide various

information to us. For example, homepages introduce their companies and advertise,

fee-based websites charge for information such as information of stock brokerage advice,

and internet shopping malls display the list of goods involving ads for various goods and

then sell the goods via the internet if the user wants to buy particular goods.

Especially these days, a mobile terminal such as a cellular phone, PCS, PDA and

the like which can connect with a website on the mternet and receive various information

have been developed and widely used around the world. Furthermore, the mobile

terminal, (i.e., IMT-2000), which can quickly transmit massive data such as moving

picture data is under development.

These mobile terminals usually use a wireless internet that extends the wired

internet that normally transmits/receives data through a conventional wired internet

network to wireless technology. The user can search the website on the internet since

these mobile terminals have a web browser.

Regarding this procedure, the user can connect with the website on the internet

using the mobile terminal by inputting an internet URL of the website using the web

browser or alternatively inputted predetermined numbers in accordance with internet address after the user has connected with the internet. However, this conventional method

for connecting with the internet is inconvenient because the user must press a button

several times to connect with the desired website.

Fig. 1A is a flowchart representing the process to conduct call connection and data

service in a mobile terminal according to the prior art.

Most services using a mobile terminal usually involve voice call or wireless

internet. The voice call can be conducted only with the input of a phone number and then

pressing a send button. However, internet connection using a web browser is a multi-step

procedure requiring operating buttons.

The prior art will be described referring to Fig. 1.

At step SI 10 the user selects either voice call or internet connection. If the user

selects the voice call, the operation for the voice call is conducted at step S115. If the user

selects the internet connection, the operation of the internet connection for data service is

conducted at step S150.

Regarding the voice call, the user inputs a phone number in step SI 15 and presses

send button in step S120. Thereafter, a corresponding call connection occurs in S125 but

the call is disconnected if the end button is pressed in step S170. As described above, the

user can conduct voice call by inputting the phone number and then operating one button.

In comparison, if the user requests internet service the user inputs an internet

connection request button in step S150, the web browser then executes in accordance with the input of the button, and the mobile terminal connects with internet network in

step S155. At first, if the user of the mobile terminal inputs the web browser execution

button, the mobile terminal executes the web browser to connect with the web server on

the internet network.

Upon connecting with an internet network and then the internet address data of

desired website, the URL of the desired website is inputted by the user in step S160. Next

the web server searches IP address in accordance with inputted internet address data in

step S165. The web server maps the mobile terminal to the website in accordance with the

searched IP address, so that the user can connect with the desired website at step S170 and

locate various information. Accordingly the user inputs the address of the desired

website.

A procedure in connecting with the internet will be described below referring to the

representative screen of the mobile terminal shown in Fig. IB. Fig. IB represents the

construction of a screen of the mobile terminal when the mobile terminal connects with

the internet according to the prior art.

Firstly, if the user of the mobile terminal inputs the internet connection button, the

wireless web browser executes to display the screen for connecting with internet shown

in step S190.

When the mobile terminal is connected with internet, the screen of the internet

address input menu to input the internet address of the website on the internet network is displayed as shown in step S192. Thereafter, when the user inputs the internet address of

the desired website on the screen of internet address input menu of mobile terminal of

step SI 90, the screen indicative of "connecting with website" as shown in step SI 94 is

displayed on the display of the mobile terminal.

Finally, after the procedure of connecting with the website is displayed, textual

information provided by the connected website is displayed on the display of the mobile

terminal as shown in step S198.

In summary, the internet connection according to the prior art is quite

inconvenient because the user has to input the internet address to connect with the website

while connecting with the internet network after executing the web browser of the mobile

terminal. Therefore, the user has to operate buttons multiple times to connect with desired

website.

In more detail, the internet connection according to the prior art has problems

since the user has to conduct a complex procedure of multi-steps. That is, the user must

input internet address or number after the web browser is executed to connect with the

website. Also, the internet connection according to the prior art is problematical because

the fee for using the wireless internet may be overcharged since the user has to input the

internet address or the number of the website while connecting with the internet network.

Also, according to the prior art, the plural operations of buttons are required when

the user requests a call or data service connection. For example, the user must initially input a phone number or search in advance the phone number in the phone number list

stored in the mobile terminal to request a call.

In more detail, the user operates buttons so that a screen of the search phone

number list is displayed on the display of the mobile terminal when the user wants to

connect a call. The user has to input name or index number or operate a direction button

multiple times to search for a phone number, so that the connection for a call is

established. Moreover, the fee is charged even while inputting a search word since a

time-use charge begins right after the web browser is executed.

Therefore, as described above, in order for the user to avoid being needlessly

overcharged fees while making requests for data service, a method has been devised such

that the user can conveniently search the list stored in the mobile terminal or the user may

request data service after a search word has already been inputted in advance.

Best Modes for carrying out the Invention

Hereinafter, preferred embodiments of the present invention will be described in

more detail with reference to the accompanying drawings.

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

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

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.

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

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

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

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

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

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

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

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

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

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". 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

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.

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

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

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

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.

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

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

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.

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

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

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. The first embodiment

Fig. 3 represents a one-button internet connection system according to a preferred

embodiment of the present invention.

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.

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

(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

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

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

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).

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 S400 the user of the mobile terminal inputs a search word in accordance

with a desired website and then presses the internet connection button on the mobile

terminal 200 in step S405. The mobile terminal 200 executes the web browser module

230, adds the connection identifier to the search word and generates the connection

request signal including the search word and the identifier in step S410. In step S415 the

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

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

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

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.

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.

4B. In more detail, the URL field 402 is the field to store an internet address, (e.g.,

'www.yahoo.com', 'www.ez-patent.co.kr'), to be connected with various websites on

internet. Further, the number field 404 is the field to store a number such as '92446',

'31728368' and the like, that connects the mobile terminal with website. Also, the phone

number field 406 is the field to store a phone number to connect the mobile terminal with

website.

Lastly, the IP address field 408 is the field to store the IP addresses of plural

websites 360 in accordance with the URL, number, phone number and the like when the

mobile terminal 200 connects with internet.

with the homepage of ΕZ Patent and Trademark Office' in Seoul, Korea will be

described.

A typical screen of the mobile terminal in steps S500, S505 and S510 is shown in

Fig. 5.

The user can input the number in accordance with the IP address of the website, for

example, '31728368' as in step S500, or secondly imput the URL in accordance with the IP address of the website, for example, 'www.ex-patent.co.kr' as in step S505. Also, in

step S510 the user can input the phone number in accordance with the IP address of the

website, for example, '025656727'.

In step S515, the internet connection request button is clicked. The mobile terminal

200 executes the web browser module 230, adds the connection identifier to the search

word, and transmits it to the DNS server 350. That is, the mobile terminal 200 transmits

the website connection request signal, (e.g., 'http://*www.ex-patent.co.kr' added with a

predetermined internet connection signal), "*" to the base terminal at the same time the

mobile terminal 200 executes the web browser.

In step S515 the screen indicative of connecting with the website is displayed on the

display of the mobile terminal 200 until the mobile terminal 200 connects with the

website. For example, a character string like 'connecting with the site' can be displayed

on the display of the mobile terminal 200 similarly as shown in the step S515 in Fig. 5.

The DNS 350 server searches the IP address information database 355, extracts the

IP address in accordance with the search word included in the website connection request

signal, and transmits it to the website during display. The mobile terminal 200 can

connect with the website using the IP address. In step S520 the connection is established,

so the web page of ΕZ Patent and Trademark Office' is displayed. The second embodiment

Fig. 6 represents the construction of a one-button service system network according

to a preferred embodiment of the present invention.

A method for providing one-button service according to the present invention can

provide service for a search allowing for the convenient input of characters as well as

internet connection. Predetermined numbers in accordance with website, code, URL,

domain, character and the like can be inputted as the search word. However, the case

character that is inputted will be described to make the description of the present

invention simple.

In the description of the method and device for providing one-button service

according to the present invention, the internet connection request button will be

indicated as a data service request button, while the DNS server 350 and the search server

370 will be indicated as a data service server 390 hereinafter.

The method and the device for providing one-button service including the service

for a search according to the second embodiment will be described below in detail.

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.

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

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

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

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.

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

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

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

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

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

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

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.

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.

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

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

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.

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.

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

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.

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. 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

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

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 "#" button on the mobile

terminal 200 for a predetermined time.

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

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

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

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

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

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

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

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

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

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 "damn", "Korea Telecom", "KTF" and the like.

In the step S860, the user inputs the data service request button after the user inputs

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

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

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

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. 8 A 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

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 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

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

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

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

600 can be HLR(Home Location Register), NLR(Nisitor 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.

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

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

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

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

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.

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,

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

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

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

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.

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.

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

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

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

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.

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

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

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

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

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

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

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,

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

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
