The content transmitter 230 transmits the corresponding content by the TCP / IP protocol.

The content information storage unit 240 stores user manager information for determining whether the content can be provided and information on the number of downloads remaining of the content.

The use manager information refers to information of a user who can download a specific content, and the remaining download count information of the content refers to information that is set in advance to control the download frequency of the specific content.

Hereinafter, an example of a method of determining whether the corresponding content can be provided using the use manager information stored in the content information storage unit 240 and the remaining download count information of the content will be described.

First, there is a method of determining whether the content is available using the use manager information, so that the content can be provided only to a user registered in advance in the content information storage unit 240.

That is, the owner of the content stores a list of friends who have the authority to download the corresponding content in the content information storage unit 240 in advance, and the content providing request received by the content request receiving unit 210 is received from the previously stored friend. In this case, the determination unit 220 may determine that the corresponding content can be provided.

As another method, the determination unit 220 may determine that the corresponding content can be provided when the content providing permission message is included in the content providing request.

The content providing permission message may be included in a content providing request, and means a message previously received from an external device by a communication terminal that has transmitted a content providing request.

In the present specification, the external device is a device for generating a content providing permission message, and may be preferably a communication terminal of the owner of the content.

That is, the user who receives the content providing permission message in the form of SMS from the person who owns the corresponding content may include the received content providing permission message in the content providing request and request the content providing server 100 to provide the content.

When the content providing request transmitted in the above process includes the content providing permission message, the determination unit 220 may determine that the corresponding content can be provided.

According to another embodiment of the present invention, there is a method of using the remaining download count information as a method of determining whether content can be provided.

The determination unit 220 may determine that the corresponding content is available when the remaining download count information stored in the content information storage unit 240 is one or more.

Of course, it is obvious that the remaining download count information stored in the content information storage unit 240 is decreased by one each time the download is performed.

Only when it is determined that the content can be provided by the determination unit 220 as described above, the content transmitter 230 transmits the corresponding content to the web server web server 330 implemented in the smart card 150.

The controller 250 controls each component of the content providing apparatus 100 (for example, the content request receiver 210, the determiner 220, the content transmitter 230, and the content information storage 240). Can be controlled.

The control unit 250 controls the determination unit 220 to determine whether the content request receiving unit 210 can provide the corresponding content to the communication terminal 170 when a request for providing the content is received from the communication terminal 170. do.

The controller 250 generates a trigger message when the determination result of the determination unit 220 is provided, and controls to transmit the generated trigger message to the web server 330 implemented in the smart card 150.

The trigger message may be transmitted in the form of an SMS as a request message for communicating with the web server 330 implemented in the smart card 150.

When a response message is received from the web server 330 implemented in the smart card 150 receiving the trigger message, a channel between the content transmitter 230 and the web server 330 implemented in the smart card 150 is set.

The controller 250 may control to transmit the corresponding content to the web server 330 implemented in the smart card 150 through the set channel.

As described above, the web server 330 implemented in the smart card 150 according to the present invention may be a smart card web server (SCWS).

In addition, the controller 250 may provide the use manager information or the remaining download count information stored in the content information storage unit 240 to the determiner 220 to determine whether the content can be provided.

In FIG. 2, the controller 250 and the determiner 220 are illustrated as separate components. However, the control unit 250 and the determiner 220 are merely illustrated to implement separate functions, and it is obvious that the controller 250 and the determiner 220 may be implemented as one circuit to perform each function.
