1 is a block diagram of a mobile communication terminal performing an application execution method using a numeric keyword according to an embodiment of the present invention, Figure 2 is an exemplary view of an application information file according to an embodiment of the present invention. .

As shown in FIG. 1, the mobile communication terminal 100 according to the present invention includes a key input unit 110, a transceiver unit 120, a storage unit 130, a display unit 140, an application manager 150, and an audio output. The unit 160 and the controller 170 are included. The mobile communication terminal 100 is coupled to the mobile communication system 180 through a communication network, and is coupled to the application providing apparatus 190 through the mobile communication system 180.

The mobile communication terminal 100 described below will be described assuming that a platform for executing an application downloaded through the application providing apparatus 190 is already installed.

The key input unit 110 is a control command for controlling the operation of the mobile communication terminal 100 from a user, a control command for executing and downloading an application (for example, a numeric keyword, an application execution command, an application selection command, etc.) It is a means for receiving input. In the present specification, a 'numeric keyword' is defined as information consisting of a combination of one or more numbers and / or letters and serving as a shortcut for executing an application. For example, the key input unit 110 may include a plurality of key buttons (for example, numeric / character keys, * or # symbol keys, one or more function keys (for example, menu keys, call keys, confirmation keys, applications). Drive key) or a touch screen.

The transceiver 120 is coupled to the application providing apparatus 190 and a communication network via the mobile communication system 180, and is input through the key input unit 110 (for example, a numeric keyword, an application selection command, etc.). ) Is transmitted to the application providing apparatus 190. In addition, the transmitter / receiver 110 may transmit data (for example, an application installation file, application information) corresponding to information (for example, numeric keywords) input and transmitted from the application providing apparatus 190 through the key input unit 110. File).

Here, the application information file may be a file including basic information of the application. As illustrated in FIG. 2, the application information file may include a name of the application, a producer, an application ID, a type, and billing information. In addition, when an application installation file corresponding to the numeric keyword is received from the application providing apparatus 190 and installed in the mobile communication terminal 100, the application information file may include information for matching the numeric keyword with the corresponding application (for example, the numeric value). Matching information for matching a keyword with an application ID). Thus, when the numeric keyword and the application driving key are sequentially input, the mobile communication terminal 100 may recognize and execute the application corresponding to the numeric keyword.

The storage unit 130 may include an operation program of the mobile communication terminal 100, an application installation file received through the application providing device 190, an application information file, and data corresponding to an application executed by a user's selection (eg, For example, if you download an attached file when you run "Hanmail", the downloaded file is saved.

The display unit 140 may input data corresponding to a command input by the user through the key input unit 110 under the control of the controller 170 (for example, an application execution screen executed by the user and input through the key input unit). Command, a selection command, and the like, and data received through the transceiver 120 (eg, an application list matching the numeric keyword received from the application providing apparatus 190) are displayed. For example, the display unit 140 may be a liquid crystal display (LCD).

 The application manager 150 manages installation information and execution history information of an application selected by the user through the key input unit 110 under the control of the controller 170.

For example, when an application corresponding to a numeric keyword input by the user through the key input unit 110 is received and installed from the application providing apparatus 190, the application manager 150 may be configured to match the numeric keyword with the corresponding application. Information may be stored in the storage 130. For this reason, when the numeric keyword and the application driving key are input through the key input unit 110, the mobile communication terminal 100 may execute an application corresponding to the numeric keyword.

The sound output unit 160 outputs a predetermined sound to the corresponding application when the application is executed. In addition, the sound output unit 160 may include a sound source chip (for example, a Yamaha sound source chip), a speaker, or the like.

The control unit 170 is a key input unit 110, the transmission and reception unit 120, the storage unit 130, the display unit 140, the application manager 150, so that the application can be downloaded and executed using the numeric keyword according to the present invention It performs a function to control the output unit 160 and the like.

Some components (eg, an application manager) of the mobile communication terminal 110 shown in FIG. 1 may be implemented in the form of a software program, and the software program may be implemented in any device (eg, in the mobile communication system 180). For example, it may be provided from a proxy server connected when the user selects an application execution function button in the key input unit 110.

Although FIG. 1 illustrates the mobile communication system 180 and the application providing apparatus 190 independently, the application providing apparatus 190 may be configured as a part of the mobile communication system 180.

3 is a flowchart illustrating an application download method using a numeric keyword according to an exemplary embodiment of the present invention, and FIG. 4 is a UI screen of an application download process using a numeric keyword according to an exemplary embodiment of the present invention. 5 is a diagram illustrating a matching relationship between a numeric keyword and an access address of a database according to an exemplary embodiment of the present invention.

Referring to FIG. 3, in step 305, the mobile communication terminal 100 receives an arbitrary numeric keyword from the user through the key input unit 110. If an application corresponding to the numeric keyword is already installed in the mobile communication terminal 100, the execution operation of the corresponding application will be performed. An operation process when the application is already installed will be described later with reference to FIG. 6, and hereinafter, it is assumed that the application is not installed.

In operation 310, the mobile communication terminal 100 accesses the download server 193 connected through the wireless communication network using the input numeric keyword. Here, the numeric keyword may be composed of a combination of one or more numbers, symbols, characters, or a combination thereof. If the numeric keyword is composed of only numbers, it may be limited to four or more digits to distinguish it from the serial number in the phone book, or may be recognized as a numeric keyword only when an application driving key is input without limiting the number of digits. In this case, if the number of digits in the numeric string of the numeric keyword is limited, it may be automatically recognized as a numeric keyword when the last digit is pressed for a predetermined time or more, similarly to the case of the speed dialing.

In addition, the numeric keyword may be set to correspond to the service or application name in order to facilitate the recognition of the user. For example, when a user wants to use a "DAUM" service, a numeric keyword may be specified to include "3286" which is a number corresponding to each letter (see FIG. 4).

For example, when the numeric keyword "** 3286" is input by the user, the mobile communication terminal 100 includes the input numeric keyword in advance and the predetermined connection address information (which is a preset address to be connected to the download server 193). Information and the entered numeric keyword, for example, "http: //downloadserver_url/dn.asp? Number_app". Here, the mobile communication terminal 100 inserts a numeric keyword input by the user at the position of number_app. The mobile communication terminal 100 connects to the download server 193 through the communication network using the converted access address information.

In operation 320, the download server 193 extracts a numeric keyword from the access address information received from the mobile communication terminal 100, and extracts an application list corresponding to the extracted numeric keyword from the database 196. That is, the download server 193 may extract the numeric keyword by extracting the information of the number_app location among the access address information. For example, if the extracted numeric keyword is '3286' and the numeric keywords '32862' and '32863' are stored in the database 196 corresponding to '3286', the download server 193 may extract the extracted numeric keyword '3286'. The application list may be generated by extracting '32862' and '32863' including '.

Here, as illustrated in FIG. 5, the database 196 may store and manage the numeric keyword and the download address information corresponding to the location information from which the respective applications corresponding to the numeric keyword can be downloaded.

In operation 325, the download server 193 transmits the extracted application list corresponding to the numeric keyword to the mobile communication terminal 100 through the communication network. The application list may include one or more application names extracted as illustrated in FIG. 4.

In operation 330, the mobile communication terminal 100 displays a list of applications received from the download server 193 on the display unit 140, and receives an arbitrary application name through the key input unit 110. A user interface screen with an application list displayed is illustrated in FIG. 4.

In operation 335, the mobile communication terminal 100 transmits application selection information corresponding to the selection of the application name to the download server 193 through the communication network. Here, the application selection information may be information indicating the order of listing the corresponding item on the application list. In addition, if each item included in the application list includes a numeric keyword, the application selection information may be a numeric keyword of the corresponding item or access address information including the numeric keyword.

In operation 340, the download server 193 searches the database 196 to read download address information for downloading the corresponding application corresponding to the application selection information. In this case, when the application selection information is enumerated information, it may be converted into a corresponding numeric keyword, and in the case of access address information, the numeric keyword may be extracted.

Subsequently, the download server 193 accesses a server device (not shown) capable of downloading the installation file of the corresponding application through the communication network using the download address information, and searches or receives the installation file of the corresponding application. Through the communication network to the mobile communication terminal 100 through.

Steps 330 to 345 will be described as an example. When the application list (for example, "next messenger", "hanmail", "next cafe") illustrated in FIG. 4 is displayed on the display unit 140 of the mobile communication terminal 100, the user selects "Hanmail". Assume it is chosen. In this case, the mobile communication terminal 100 generates and downloads the numeric keyword "** 32862" including the numeric keyword (that is, ** 3286) and "2" including the list order of "Hanmail" which were initially transmitted. Send to server 193. The download server 193 searches the database 196 and reads out download address information corresponding to the numeric keyword "** 32862" if it exists. Subsequently, the download server 193 accesses a server device corresponding to the download address information through a communication network, searches for or receives an installation file of the corresponding application (ie, "Hanmail"), and transmits it to the mobile communication terminal 100. Of course, since the download server 193 has already recognized the item information in the application list as described above, the mobile communication terminal 100 may transmit only the list order information.

In operation 350, the mobile communication terminal 100 receives (ie, downloads) an installation file of a corresponding application from the download server 193 through a communication network. In this case, the mobile communication terminal 100 may also receive the information file of the corresponding application.

Subsequently, the mobile communication terminal 100 determines whether reception of an application installation file is completed in step 360.

If the reception of the application installation file is not completed, the process waits at step 360 until the reception of the application installation file is completed.

However, if the reception of the application installation file is completed, in step 370, the mobile communication terminal 100 installs the application using the application installation file.

When the installation of the corresponding application is completed, the mobile communication terminal 100 may update the application information file so that the corresponding application corresponds to the numeric keyword. This is because the mobile communication terminal 100 updates the application ID in the application information file (for example, illustrated in FIG. 2) with the numeric keyword information so that the corresponding application is immediately executed without being newly downloaded when the numeric keyword is input. To do this. However, the updating of the application ID to match the numeric keyword may be a step performed only when the application ID is previously set as information different from the numeric keyword.

So far, the process of downloading and installing an application corresponding to the input numeric keyword is not yet installed in the mobile communication terminal 100 with reference to FIGS. 3 to 5.

In addition, a method in which one numeric keyword is set to correspond to a plurality of applications so that when a numeric keyword is input, an application list corresponding to the plurality of applications is transmitted to the mobile communication terminal 100 so that the user can select an application to install. It was. In addition, the information file of the application installed in the mobile communication terminal 100 is updated to correspond to the numeric keyword input by the user so that the installed application may be executed later even if the user inputs only the numeric keyword.

However, the above-described method may be inconvenient due to the sameness of the numeric keywords to be input when the user wants to execute or download another application set to correspond to the same numeric keyword. Therefore, when the user inputs a numeric keyword, the mobile communication terminal 100 may display a chat window before executing the corresponding application to check whether to execute the installed application or to download another application. Of course, when the user instructs the execution of the application using the finally generated numeric keyword (that is, the first numeric keyword and the order of listing), the corresponding application may be executed immediately.

In addition, according to another preferred embodiment of the present invention, there is provided an application execution method and apparatus using a numeric keyword is set so that one numeric keyword and one application correspond.

In other words, when the numeric keyword and the application are set as 1: 1, and the user inputs a random numeric keyword, the corresponding application is executed if the corresponding application exists, but if it does not exist, the connection address information is transmitted to the download server 193. You can request to download the application.

Therefore, in this case, the aforementioned steps 320 to 335 of FIG. 5 may be omitted. In this case, the user may instruct the execution of the corresponding application only by inputting the corresponding numeric keyword.

In addition, according to another preferred embodiment of the present invention, there is provided a method and apparatus for executing an application using a numeric keyword in which each item included in the application list includes download address information.

That is, when each item included in the application list includes the download address information and the user selects an arbitrary item, the mobile communication terminal 100 directly accesses the server device corresponding to the corresponding download address information and installs the installation file of the corresponding application. You can also download it.

In this case, step 335 to step 345 of FIG. 3 may be omitted.

6 is a flowchart illustrating an application execution method using numeric keywords according to an exemplary embodiment of the present invention. In order to execute an application using a numeric keyword according to the present invention, the corresponding application must be installed as described above.

In step 610, the key input unit 110 sequentially performs a numerical keyword corresponding to the application to be executed by the user and an application driving key (that is, a function key preset to indicate that the numeric keyword indicates the execution of the corresponding application). It receives the input to pass to the control unit 170.

In operation 620, the application manager 150 determines whether an application corresponding to the numeric keyword received from the key input unit 110 is installed under the control of the controller 170.

If an application corresponding to the numeric keyword is installed, in step 630, the controller 170 executes the application corresponding to the numeric keyword.

For example, it is assumed that an application corresponding to the numeric keyword "** 32862" is "Hanmail" and "Hanmail" is downloaded and installed from the application providing apparatus 190. In this case, when the numeric keyword "** 32862" and the application driving key are sequentially input by the user, the application manager 150 searches for the registered application installation information and installs an application corresponding to the numeric keyword "** 32862". Determine if there is. If an application corresponding to the numeric keyword "** 32862" is installed, the application is executed immediately. However, if the corresponding application is not installed, as described above, the numeric keyword may be transmitted to the application providing apparatus 190 through the communication network to download the corresponding application corresponding to the numeric keyword.

Although not shown in FIG. 6, as described above, when a plurality of applications corresponding to one numeric keyword exist, a dialog for checking whether the input numeric keyword is for execution of an already installed application or for downloading another application. This displayed step may be further included.

As described above, by providing an application execution method and apparatus using a numeric keyword according to the present invention, an application installed in the mobile communication terminal can be conveniently executed by inputting only the numeric keyword.

In addition, the present invention has an effect that can be downloaded quickly and conveniently without a separate procedure when the application requested to be executed by the input of the numeric keyword is not installed in the mobile communication terminal.

Although the above has been described with reference to a preferred embodiment of the present invention, those skilled in the art to which the present invention pertains without departing from the spirit and scope of the present invention as set forth in the claims below It will be appreciated that modifications and variations can be made.
