Referring to FIG. 1, when the external device 100 is connected, the system for interworking with the mobile communication terminal and the external device runs a wireless Internet platform to execute an application for interworking with the external device 100. If there is no application for interworking with the external device 100 in the mobile communication terminal 110, an application providing server for providing the application to the mobile communication terminal 110 through a mobile communication network ( 120).

When an external device is connected, the mobile communication terminal 110 identifies the external device and executes the corresponding application to interwork with the external device. However, when the external device 100 provides a new function other than a commonly used charger, an application for allowing the external device 100 and the mobile communication terminal 110 to interoperate should be executed.

That is, when the external device 100 is connected, the mobile communication terminal 110 drives a wireless internet platform such as a wireless internet platform for interoperability (WIPI) or a wireless internet terminal open platform (WI-TOP), The stored application list is provided to the external device 100.

In addition, when an application download request command is received from the external device 100, the mobile communication terminal 110 accesses the application providing server 120 and downloads the corresponding application.

Detailed description of the mobile communication terminal 110 performing the above role will be described with reference to FIG. 2.

The application providing server 120 maps and stores a corresponding application for each application ID. Accordingly, when the application download command is received from the mobile communication terminal 110, the application providing server 120 extracts the corresponding application and provides the extracted application to the mobile communication terminal 110.

That is, since the application download command includes an application ID to be downloaded and a mobile communication terminal identification number, the application providing server 120 extracts an application corresponding to the application ID and corresponds to the mobile communication terminal identification number. It transmits to the mobile communication terminal (110).

Referring to FIG. 2, the mobile communication terminal for interworking with an external device includes an input unit 200 for receiving a user command, a controller 210 for controlling the overall operation of the mobile communication terminal, and a storage unit 220 for storing various data. ), A wireless communication unit 250 for performing wireless communication, a display unit 230 for outputting a current state of a mobile communication terminal or an event processing state requested by a user, an audio unit 240 for outputting a voice signal, and an external device.

The input unit 200 serves to receive a user command. For example, the input unit 200 may refer to a keypad or a keyboard.

The storage unit 220 stores application information for interworking with an external device and a wireless Internet platform such as WIPI or WI-TOP according to characteristics of a mobile communication terminal. The application information is stored by mapping an application ID and a corresponding application.

The application ID refers to an ID value uniquely assigned to each application (game, browser, 'June Player', etc. downloaded to the mobile communication terminal). The above value is used to manage the application in the terminal (for example, the GoStop game is downloaded, and may be used when the terminal determines whether the game is a downloaded game), linkage (call 'mPlayon' ◎ on a browser, or in another application). Used when calling a browser or 'June Player').

In addition, when the application is downloaded, the application ID may be stored in a separate storage area such as a DD (Download Description) file or a WAM (Central Module for managing an application on the WIPI).

The external device interface unit 260 may be connected to an external device. For example, the external device interface unit 260 may be a TTA 24-pin interface.

The wireless internet platform driver 270 receives a WIPI driving command or a WI-TOP driving command from the external device after the external device is connected through the external device interface unit 260.

An application download command including a terminal identification number is transmitted to the application providing server.

Then, the application providing server extracts the application corresponding to the application ID and transmits it to the mobile communication terminal corresponding to the mobile terminal identification number.

When the application execution command is received through the external device interface unit 260, the application execution unit 290 searches for and executes the corresponding application in the storage unit 220. That is, since the application execution command includes an application ID to be executed, the application search unit 280 extracts and executes an application mapped to the application ID from the storage unit 220.

Referring to FIG. 3, when an external device is connected to a mobile communication terminal (S300), the external device transmits a WIPI driving command to the mobile communication terminal (S302).

For example, when the external device is connected through the TTA 24-pin interface of the mobile communication terminal, it recognizes the connection with the mobile communication terminal by checking the power supply or the battery ID.

When the external device recognizes the connection with the mobile communication terminal as described above, the external device transmits a WIPI driving command to the mobile communication terminal, where the WIPI terminal operates on some external interface (EIF) commands of the WI-TOP. However, since the WI-TOP terminal does not operate for the EIF command of the WIPI, the external device transmits a WIPI driving command to the mobile communication terminal.

After the execution of step 302, if a WIPI driving response is received from the mobile communication terminal within a predetermined time (S304), the external device determines that the mobile communication terminal is a WIPI terminal (S306).

When the mobile communication terminal is determined as the WIPI terminal as described above, the external device performs an interface with the mobile communication terminal using a command operated in the WIPI.

After performing step 306, the external device transmits an application list request command to the mobile communication terminal to check whether an application for interworking with the mobile communication terminal exists in the mobile communication terminal (S308).

After performing step 308, if an application list is received from the mobile communication terminal (S310), the external device determines whether an application ID for interworking with the mobile communication terminal exists in the application list (S312).

Since the application list includes an application ID, the external device may determine whether a required application ID exists in the application list.

As a result of the determination in step 312, if the corresponding application exists in the application list, the external device transmits an application execution command to the mobile communication terminal (S314). The application execution command includes an application ID to be executed.

After the execution of step 314, if the application execution response is received from the mobile communication terminal (S316), the external device performs interworking with the mobile communication terminal (S318).

It is determined whether a WI-TOP drive response is received from the operation S322.

As a result of the determination in step 322, if the WI-TOP driving response is received from the mobile communication terminal within a predetermined time, the external device determines that the mobile communication terminal is a WI-TOP terminal (S324) and performs step 308. If it is determined that the mobile communication terminal is a WI-TOP terminal, the external device performs an interface with the mobile communication terminal using a WI-TOP command.

If it is determined in step 322 that the WI-TOP driving response is not received from the mobile terminal within a predetermined time, the external device determines that an error (S326).

If it is determined in step 312 that the corresponding application does not exist in the application list, the external device transmits an application download request command to the mobile communication terminal (S328). The application download request command includes an application ID to be downloaded and an application providing server address.

After the execution of step 328, if an application download completion response is received from the mobile communication terminal (S330), the external device performs step 314.

Referring to FIG. 4, after a connection of an external device is detected (S400), when a WIPI driving command is received from the external device (S402), the mobile communication terminal determines whether a WIPI terminal is present (S404). That is, when the WIPI driving command is received from the external device, the mobile communication terminal determines whether the WIPI is stored in the wireless Internet platform in the storage unit.

If the WIPI is stored in the storage unit as a result of the determination in step 404, the mobile communication terminal drives the WIPI and then transmits a WIPI driving response to the external device (S406).

After the execution of the step 406, the mobile communication terminal receives an application list request command from the external device (S408), extracts an application list including the ID of the application stored in the storage unit and transmits it to the external device (S410). ).

After the execution of step 410, the mobile communication terminal receives an application execution command from the external device (S412), executes the application (S414), and transmits an application execution response to the external device (S416), Interwork with an external device is performed (S418).

That is, the mobile communication terminal extracts and executes an application corresponding to an application ID included in the application execution command from the storage unit, and then transmits an application execution response.

If the determination result of step 404 is not a WIPI terminal, the mobile communication terminal determines whether a WI-TOP driving command is received from the external device (S420). That is, if the mobile communication terminal does not transmit a response to the WIPI driving command transmitted from the external device, the external device determines that the mobile communication terminal is a WI-TOP terminal and sends a WI-TOP driving command to the mobile communication terminal. Send it.

As a result of the determination of step 420, when the WI-TOP driving command is received from the external device, the mobile communication terminal determines whether the WI-TOP exists in the storage unit (S422).

If the WI-TOP exists in the storage unit as a result of the determination in step 422, the mobile communication terminal drives the WI-TOP, and then transmits a WI-TOP driving response to the external device (S424), and performs step 408. . When WI-TOP is driven in the mobile communication terminal, the mobile communication terminal and the external device perform an interface using a WI-TOP command.

If it is determined in step 420 that the WI-TOP driving command is not received from the external device, the mobile communication terminal outputs an error message (S426).

If the application execution command is not received as a result of the determination of step 412, the mobile terminal determines whether an application download request command is received from the external device (S428). The application download request command includes an application ID and an address (URL) of an application providing server providing a corresponding application.

When the application download request command is received from the external device as a result of the determination of step 428, the mobile communication terminal accesses the URL included in the application download request command (S430), and downloads the corresponding application to download the response to the external device. After transmitting (S432), step 412 is performed.

A detailed description of how the mobile communication terminal accesses the application providing server to download an application will be described with reference to FIG. 6.

Referring to FIG. 5, after a connection of an external device is detected (S500), if a WIPI driving command is received from the external device (S502), the mobile communication terminal determines whether the WIPI terminal is present (S504). That is, when the WIPI driving command is received from the external device, the mobile communication terminal determines whether the WIPI is stored in the wireless Internet platform in the storage unit.

If the WIPI is stored in the storage unit as a result of the determination in step 504, the mobile communication terminal drives the WIPI and then transmits a WIPI driving response to the external device (S506).

Then, the external device transmits application information for interworking with the mobile communication terminal to the mobile communication terminal. The application information includes an application ID and an application providing server address.

When the application information is received from the external device (S508), the mobile communication terminal determines whether the corresponding application is stored in the storage unit by using the application ID in the application information (S510). That is, the mobile terminal determines whether the application ID exists in the storage unit.

As a result of the determination in step 510, if the corresponding application exists in the storage unit, the mobile communication terminal executes the corresponding application (S512), transmits an application execution response to the external device (S514), and performs interworking with the external device. (S516).

If the determination result of step 504 is not a WIPI terminal, the mobile communication terminal determines whether a WI-TOP driving command is received from the external device (S520).

As a result of the determination of step 520, when the WI-TOP driving command is received from the external device, the mobile communication terminal determines whether the WI-TOP exists in the storage unit (S522).

If the WI-TOP exists in the storage unit as a result of the determination in step 522, the mobile communication terminal drives the WI-TOP, and then transmits a WI-TOP driving response to the external device (S524), and performs step 508. . When the WI-TOP platform is driven in the mobile communication terminal, the mobile communication terminal and the external device perform an interface using a WI-TOP command.

If it is determined in step 520 that the WI-TOP driving command is not received from the external device, the mobile communication terminal outputs an error message (S526).

If it is determined in step 510 that the corresponding application does not exist in the storage unit, the mobile communication terminal accesses the application providing server address in the application information (S528), and downloads the corresponding application (S530). Perform.

Referring to FIG. 6, when an application download command is received from the mobile communication terminal (S600), the application providing server extracts an application corresponding to the application ID included in the application download command (S602).

That is, since the application download command includes a mobile communication terminal identification number and an application ID to be downloaded, the application providing server extracts a corresponding application using an application ID.

Then, the application providing server transmits the extracted application to the corresponding mobile communication terminal using the mobile communication terminal identification number (S604).
