In some cases, such embodiments may be implemented by the controller 180.

In accordance with a software implementation, embodiments such as procedures or functions may be implemented with separate software modules that perform at least one function or operation. The software code may be implemented by a software application written in a suitable programming language. Also, the software codes may be stored in the memory 160 and executed by the control unit 180. [

Hereinafter, with reference to FIG. 1, a detailed description will be made of an organic operation relationship among components of a mobile communication terminal in order to perform an operation of the mobile communication terminal according to the present invention.

Based on the terminal and the system described above, the terminal according to the embodiment of the present invention can restrict the function of receiving and printing contents. Documents such as public agencies need to be restricted to specific use only. For example, when a terminal downloads a document from a public institution or a content provided by a specific content provider through the wireless Internet module 113, the content can be printed through the printer. In this case, if the content is printed and used without restriction on the use of the terminal as described above, the content may be used indiscriminately, which may cause confusion. Therefore, when accessing such content through a personal computer, the content provider can make the content not only downloaded but browseable. Alternatively, it is possible to output only one output to the printer connected to the personal computer after reading, and not to browse after that. In this case, the user should try to access the content again. In this case, the provider providing the content may limit the attempts of the personal computer to access the content or the number of times that the content is copied, printed and used indiscriminately.

On the other hand, since the terminal can only print a content when there is a printer connected to the terminal, it is possible to output the content only when the content is downloaded and connected to a printer or the like. However, there are many cases where restrictions are set on accessing and using the content such that the terminal can not download the content and only the content is set to be browsed.

Assume that the content is restricted by the content provider as illustrated above. Herein, the use restriction is limited to one print, for example, limited in the number of times of downloading and downloading of contents. The content provider can configure the content so that the content includes the content identifier and the identification information for identifying the content use restriction information and the content as described above. That is, the content may no longer function when used in accordance with the usage restriction information. For example, when the content is a document, printing may not be performed when additional printing is performed other than a predetermined number of times, or the print menu on the content may be deleted.

When the content provider prints the content, the content provider transmits the usage notification generation information to the terminal in parallel with the downloading of the content or downloading the content so that the terminal can notify that the content has been used (i.e., printed) . The usage notification generation information includes information that allows the content to be notified that the content has been used, for example, the usage notification generation information includes a communication address (e.g., a telephone number or an IP address) of a server that can receive .

The terminal can access the server operated by the content provider through the wireless communication unit 110 and download the content including the usage restriction information. For example, it is possible to access content including usage restriction information through the wireless Internet module 113 of the terminal and download the content. The content including the usage restriction information and the reception information about the content may be stored in the memory 160. [

The terminal can output the contents including the usage restriction information to the connected printer. The control unit 180 may include usage restriction information and recognize the downloaded content. Then, the control unit 180 can output the content according to the use restriction information of the content. For example, the terminal may be connected to the printer device using the short-range communication module 114 including the Bluetooth function, or may be connected to the printer through the interface unit 170. The connected printer has a PictBridge function and can directly output the content to be printed by the terminal.

The control unit 180 of the terminal can generate the content output information when outputting the downloaded content as described above. The content output information may include information such as whether or not the content is output, whether the output is successful, the size of the output content, the date and time of output, and the output format. When the content is output through the terminal, the controller 180 generates a message indicating that the content is used by using the content output information, and transmits the generated message to the content provider using the usage notification generation information can do. The message also includes identification information of the content. That is, when the terminal uses the limited-use content within the limited range, the terminal can transmit the use of the restricted content to the server (or the content provider) through the wireless communication unit 110 together with the identification information of the content.

The content provider can receive identification information of the content and the content output information to confirm whether the content is used within a limited range. When the same terminal receives or uses the same content in the future, the terminal can be charged with the same.

In the foregoing, the terminal related to the present invention has been examined from the viewpoint of components according to functions.

Also, the third user input unit 245 can operate as a hot-key for activating a special function in the terminal.

The microphone 122 may be implemented in a form suitable for receiving a user's voice, other sounds, and the like.

The interface unit 170 is a channel through which a terminal related to the present invention can exchange data with an external device. For example, the interface unit 170 may be a wired or wireless connection terminal for connecting to an earphone, a port for short-range communication (for example, an IrDA port, a Bluetooth port, a wireless LAN port a wireless Lan port), or power supply terminals for supplying power to the terminal.

The interface unit 170 may be a card socket that accommodates an external card such as a SIM (subscriber identification module) or a UIM (user identity module), a memory card for information storage, and the like.

A power supply unit 190 for supplying power to the terminal 100 is mounted on the second rear case 235 side.

The power supply unit 190 may be detachably coupled to a rechargeable battery for charging or the like.

Fig. 3 is a perspective view of the terminal shown in Fig. 2 as viewed from the back. Fig.

Referring to FIG. 3, a camera 121 may be further mounted on the rear surface of the second rear case 235 of the second body 205. The camera 121 mounted on the second body 205 has a photographing direction which is substantially opposite to that of the camera 121 of the first body 200 and is different from the camera 121 of the first body 200 Pixel.

For example, the camera 121 of the first body 200 has low pixels so that it is easy to capture a face of the user and transmit the captured image to the other party in case of a video call or the like, and the camera 121 of the second body 205 It is preferable to have a high pixel since a general subject is photographed and is not immediately transferred.

A flash 250 and a mirror 255 may be additionally disposed adjacent to the camera 121 of the second body 205. The flash 250 shines light toward the subject when the subject of the subject is photographed by the camera 121 of the second body 205.

[ Similarly, the PSTN 290 connects to the MSC 280, the MSC 280 connects to the BSCs 275, and the BSCs 275 communicate with the BSs 270 ).

Although not shown in the figure, the MSC 280 may be connected to a network based on an IP address. The terminal may be connected to a content providing server that provides content that is limited in use through a communication network connected to the BS 270, the BSC 275, the MSC 280 and the MSC 280. The terminal may download and store contents including identification information and usage restriction notification information through a communication network connected to the BS 270, the BSC 275, the MSC 280 and the MSC 280. The stored content may include usage restriction information. When the terminal uses the content within the usage restriction range using the printer, the terminal generates detailed information on usage of the content as a message containing content output information, and transmits the generated message to the MSC 280 via the MSC 280 To the content provider providing the content or to the content provider through the communication network connected to the MSC 280. [

5 is a flowchart showing an embodiment of a content processing method according to the present invention. An embodiment of a content processing method according to the present invention will be described with reference to FIG.

First, the terminal accesses a server of a content provider and downloads corresponding content (S110). At this time, the content includes identification information of the content, use restriction information in which a use restriction range is set. The content provider may include the usage notification generation information, which is information that can be notified of the use of the content, through the content server, or may transmit the usage notification generation information to the terminal in parallel with the downloading of the content. The content whose use is restricted may include usage restriction information on whether or not the content is the use-restricted content. Such content includes information that enables the terminal to activate the function of restricting further use of the content, such as when the terminal outputs the content. For example, if the content is a document, it may be created so as to have the function of not being further printed or having the print menu of the content deleted. The content may include usage notification generation information. The usage notification generation information of the content includes a communication address (for example, a telephone number or an internet protocol (IP) address) of a server to be transmitted. Usage notification generation information is described in detail below.

In operation S120, it is determined whether the content is content that is restricted in use. If the content received by the terminal is limited in use, the terminal may separately record and store the received information of the content. The receiving information of the content may be generated using the usage notification generating information of the content when downloading the content. That is, the terminal can record information about the server and the content in which the content is stored. However, the step S120 may be optional depending on the functional configuration of the terminal.

The content stored in the terminal is connected to an output device to output the content and generate content output information (S130). The terminal can be connected to the printer using a printer having a PictBridge function or a short-range communication module such as Bluetooth.

When outputting the content to the printer, the terminal outputs the content to the printer, generates a message including the content output information, and transmits the generated message to the content server (S140). The content output information may include information such as whether or not the content is output, whether the output is successful, the size of the output content, the date and time of output, and the output format. When the content is output through the terminal, the terminal may transmit the content output information and the usage notification information to a server that receives the content or a content provider that provides the content.

When the message is transmitted, the usage notification generation information received in the content reception step can be used.

The content provider can receive the message including the identification information of the content and the content output information and confirm whether the use of the content is restricted.
