After the call, the phone number of the call is updated and stored in the phone book of the memory 250.

The input / output controller 242 outputs the data processed by the data processor 246 or transfers the data input from the outside to the data processor 246 for processing.

After the phone number or keyword is input from the input unit 210, the data determination unit 244 determines whether to perform its own phone function or use a server according to a function selected by the user.

The data processor 246 retrieves and outputs data such as a phone book name and a phone number from the phone book according to a phone number or keyword input by the user. In addition, the data received from the dialing server 140 is displayed.

The memory 250 stores data for the telephone book. Here, the phone book includes information on a keyword (name), a phone number, an email address, a homepage address, a photo / avatar, and metadata. Here, metadata refers to data extracted from some other information, for example, an address. Metadata can be used primarily for keyword searches.

The communication unit 260 transmits and receives a voice signal for a telephone call or data for data communication. The transmitter 262 transmits a voice signal or data to the mobile communication network, and the receiver 264 receives the voice signal or data from the mobile communication network.

Next, with reference to Figures 3 and 4 will be described in detail the telephone book update method according to an embodiment of the present invention.

3 is a flowchart illustrating an operation of updating a phone book of a mobile terminal, and FIG. 4 is a flowchart illustrating an operation of a dialing server that provides a text dialing service to a mobile terminal for updating a phone book.

First, the user selects a "dialing menu" through the input unit 210 from a plurality of menus of the mobile terminal 110 in order to make a call to a target person who wants to talk (S302).

When a dialing menu is selected from the input unit 210 by the user, the controller 240 provides a phone number input box to the display unit 220 (S304). Of course, the controller 240 may read the list of the telephone book from the memory 250 and provide the list to the display 220. In addition, the controller 240 may provide a list of recent calls or a list of speed dial numbers to allow the mobile terminal 110 to make a selection. In addition, the input unit 210 may enter a keyword as well as a telephone number in the telephone number input field.

Accordingly, the user inputs a phone number or a shortcut number and a keyword into the phone number input box through the input unit 210 (S306). In this case, the user may select a call target number from the list of the phone book or select a speed dial number from the speed dial list.

Subsequently, the user selects or inputs a phone number, a speed dial number, or a keyword through the input unit 210, and then requests a call by inputting a call key (S308).

When a call key is input from the input unit 210, the controller 240 searches whether the telephone number, a shortcut number, or a keyword selected or input through the input unit 210 exists in the telephone unit of the memory 250 (S310).

When a phone number or a speed dial number or a keyword selected or input through the input unit 210 is present in the phone unit of the memory 250 (S312), the controller 240 selects or inputs the phone through the input unit 210. The phone book name and the phone number corresponding to the number, the speed dial number, or the keyword are read from the phone book of the memory 250 and displayed on the screen through the display unit 220 (S314). For example, the telephone book name may be "LG Electronics" and the telephone number may be "02-578-3214".

Meanwhile, the controller 210 may search for a phone book name and a phone number that is similar to or include them even though the input phone number, the speed dial number, or the keyword is not completely matched and displayed on the screen through the display unit 220.

For example, if "ㅎ" is entered in the phone number input field, the phone book name and phone number similar to "ㅎ" or contain "ㅎ" are searched in real time and displayed on the screen through the display unit 220 in the order of high similarity. Can be marked on. For example, when the number "1" is input in the telephone number input field, the phone book name and the telephone number including "1" are searched in real time and displayed on the screen through the display unit 220 in the order of high similarity. Can be.

The control unit 240 transmits the phone book name and phone number to the dialing server 140 through the communication unit 260 (S316). Meanwhile, the controller 240 may attempt to text dial by transmitting a keyword to the dialing server 140 through the communication unit 260.

However, if the phone book name and phone number are not present in the phone book of the memory 250, the control unit 240 dials the phone number selected or input through the input unit 210, thereby making a normal call call. It is controlled to lose (S318).

On the other hand, during a call after inputting a keyword, if the keyword, for example, a phone book name and phone number corresponding to “LG electronic” does not exist in the memory 250, the input keyword is transmitted to the dialing server 140. The call may be performed by using a phone book name and a phone number stored in the dialing server 140 corresponding to the input keyword.

On the other hand, when the phone book name and phone number are received from the mobile terminal 110, the dialing server 140 searches the dialing database 150 and determines whether the received phone book name and phone number are valid numbers (S402).

That is, the dialing server 140 is valid if a phone book name and a phone number match the phone book name and phone number received from the mobile terminal 110 among the plurality of phone book names and phone numbers stored in the dialing database 150. Judging by it. However, it is determined to be invalid when there is no matching telephone book name and telephone number.

For example, the dialing server 140 has a phone book name stored in the dialing database 150 as "LG Electronics" and a phone number "02-578-3214", and a phone book received from the mobile terminal 110. If the name is "LG Electronics" and the telephone number is "02-578-3214", it is determined to be valid, and if the telephone number is "02-123-5678", it is determined to be invalid.

Meanwhile, the validity may be determined only by using a phone number using a database stored in a general phone number server. For example, in the above example, if "02-578-3214" exists in the telephone number server, it is determined to be valid, and if the telephone number does not exist, it is determined to be invalid.

The dialing server 140 allows a normal call call to be made when the phone book name and / or phone number received from the mobile terminal 110 is valid (S318), and when it is not valid (S404), it is not a valid number. Providing a message, for example, a voice message or a text message to inform the mobile terminal 110 (S406).

Subsequently, the dialing server 140 transmits a guide message "Do you want to perform text dialing?" To the mobile terminal 110 to provide a text dialing service (S408). In this case, the text dialing service provides the mobile terminal 110 with a menu of “1. Immediate call”, “2. Call after receiving a message”, and “3. Call termination” to be selected by the mobile terminal 110. .

When the user of the mobile terminal 110 wants to conduct a call immediately, the user selects and inputs an "immediate call" through the input unit 210 of the mobile terminal 110 (S410).

When " immediate call " is selected from the mobile terminal 110, the dialing server 140 searches the dialing database 150 using the received phone book name as a keyword, and searches for a telephone number corresponding to the keyword (S412).

When the phone number corresponding to the keyword is retrieved from the dialing database 150, the dialing server 140 dials the searched phone number to make a call call (S414).

Thereafter, when the call call of the mobile terminal 110 is terminated, the dialing server 140 transmits the phone number where the mobile terminal 110 performs the call call to the mobile terminal 110 (S416) (①). .

On the other hand, the mobile terminal 110 updates and stores the telephone number received from the dialing server 140 to the telephone book of the memory 250 (S320).

Accordingly, although the current phone number of the target user to call is changed, even if the telephone number of the called party stored in the phone book of the mobile terminal 110 is not updated, the user can perform a telephone call with the called party. The changed phone number can be automatically updated and stored in the phone book of the mobile terminal 110.

In addition, the present invention can update the phone book information in the same manner even after performing a function such as an email transmission, a homepage connection, a message transmission, etc. in addition to a call call. In order to perform e-mail transmission, homepage access, message transmission, etc., communication information about the telephone book and dialing server 140 of the memory 250 of the mobile terminal 110, for example, e-mail address, homepage address or URL, The message transfer address or telephone number must be stored.

Meanwhile, the mobile terminal 110 should transmit the email address, the homepage address or URL, the message transmission address or the telephone number to the dialing server 140 together with the telephone number. On the other hand, the dialing server 140 compares the information and the information stored in the database to determine the validity in the same manner as the validity determination by the telephone number above to send this communication information along with email transmission, homepage access, message transmission To 110. Finally, the mobile terminal 110 may update or delete the transmitted communication information to the phone book of the memory 250.

On the other hand, in the case of providing a text dialing service of the dialing server 140, when "call after receiving a message" is selected from the mobile terminal 110 (S420), the dialing server 140 is currently connected to the mobile terminal wirelessly ( End the call with 110) (S422).

The dialing server 140 searches for a telephone number corresponding to the keyword in the dialing database 150 using the telephone book name received from the mobile terminal 110 as a keyword (S424).

Subsequently, the dialing server 140 generates a message using the retrieved telephone number as a caller, and transmits the generated message to the mobile terminal 110 (S426).

Here, the message transmitted from the dialing server 140 to the mobile terminal 110 includes a telephone number corresponding to the name of the telephone book that the user wants to talk with, for example, a callback number.

In contrast, when the mobile terminal 110 receives a message including a phone number corresponding to a phone book name from the dialing server 140 (S322), the controller 240 displays a message including the phone number on the display unit 220. Mark it through.

The user checks a message including a phone number corresponding to a phone book name through the display unit 220, inputs a call key through the input unit 210, and the control unit 240 makes a call through the communication unit 260. Perform (S324)

After that, when the call is terminated, the mobile terminal 110 updates and stores the telephone number of the call 250 in the telephone book of the memory 250 (S326).

Therefore, the user of the mobile terminal 110 receives the message including the telephone number, so that parsing of the text message is unnecessary, and the server reconnection process is unnecessary.

On the other hand, when the call termination is selected from the mobile terminal 110 at the time of providing the text dialing service of the dialing server 140 (③), the dialing server 140 is currently connected to the mobile terminal 110 wirelessly by itself. End the call with.

On the other hand, after the call with the dialing server 140 is terminated, the control unit 240 of the mobile terminal 110 displays via the display unit 220 as a pop-up whether or not to delete the telephone number that attempted the current call in the phone book ( S330).

Subsequently, when the deletion is selected from the input unit 210 by the user (S332), the controller 240 deletes and updates the telephone number of the telephone call of the memory 250, at which the current call is attempted (S334).

Therefore, the user can delete unnecessary or invalid telephone numbers from the telephone book of the mobile terminal 110, thereby managing the telephone book of only valid information.

As described above, according to the present invention, even if a user does not know information such as a telephone number, an e-mail address, a homepage address, etc., a call can be easily performed using the telephone book name as a keyword. Also, after receiving a message including a phone number from the server, the call can be made by entering a call key without a server reconnection process or a parsing process of a text message, thereby making it easier to recall later. In addition, since the phone book information is automatically updated or deleted after the call, only a phone number that can be actually called remains on the phone book, thereby eliminating the possibility of redialing a wrong number later.
