Hereinafter, with reference to FIG. 1, in order to perform the operation of the mobile communication terminal according to the present invention, the organic operation relationship between each component of the terminal will be described in detail.

Based on the terminal and the system described above, the terminal according to an embodiment of the present invention can limit the function of receiving and printing content. Documents such as public institutions need to be restricted to specific uses. For example, when a terminal downloads a document of a public institution or a content provided by a specific content provider through the wireless internet module 113, the content may be printed through a printer. In this case, if the content is printed and used through the terminal as described above, the content may be used indiscriminately, which may cause confusion. Thus, when accessing such content through a personal computer, the content provider may allow the content to be viewed and not downloaded. Alternatively, after reading, only one output to the printer connected to the personal computer may be possible, and then not read. In this case, the user must try to access the content again. In this case, the provider who provides the content can limit the number of attempts by 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 print the contents only when there is a printer connected to the terminal, the contents can be output only when the contents are downloaded and connected to the printer. However, there are many cases in which restrictions on access and use of the contents are set such that the terminal cannot download the contents but can only view the contents.

As illustrated above, assume that content has been restricted for use by a content provider. In this case, the usage limit is an example in which the content is downloaded and the number of times of the download is limited, for example, only one printing is possible. The content provider may configure the content such that the content identifier and the content use restriction information and the identification information identifying the content are included in the content. That is, the content may no longer function when used according to the usage restriction information. For example, when the content is a document, when the user wants to perform additional printing other than a predetermined number of times, the printing may be prevented or the print menu on the content may be deleted.

When the content provider is printed on the terminal from which the content has been downloaded, the content provider transmits usage notification generation information to the terminal to be included in the content or in parallel with the download of the content so that the terminal can notify that the content has been used (that is, printed). You can do that. The usage notification generation information includes information enabling notification of that content has been used. For example, the usage notification generation information includes a communication address (eg, a telephone number or an IP address) of a server that can be received. .

The terminal may 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, the wireless internet module 113 of the terminal may access and download the content including the usage restriction information. Content including the usage restriction information and received information about the content may be stored in the memory 160.

The terminal may output the content including the usage restriction information to the connected printer. The controller 180 may include the usage restriction information and recognize the downloaded content. The controller 180 may output the content according to the usage 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 printed by the terminal.

The controller 180 of the terminal may generate content output information when the downloaded content is output as described above. The content output information may include information such as whether the content is output, whether the output is successful, the size of the output content, the output date and time, the output format, and the like. When the content is output through the terminal, the controller 180 generates a message for notifying that the content is used by using the content output information, and sends the generated message to the content provider using the usage notification generation information. can do. The message also contains identification information of the content. That is, when the restricted content is used within the limited range, the terminal may transmit whether to use the content with the identification information of the content through the wireless communication unit 110 to the server (or the content provider).

The content provider may receive identification information of the content and the content output information to confirm whether the content has been used in a limited range. If the same terminal later receives or uses the same content, it can be charged for this.

BSC 275 provides call resource allocation and mobility management functionality, including the organization of soft handoffs between base stations 270. In addition, the BSC 275 transmits the received data to the MSC 280, and the MSC 280 provides an additional transmission service for connection with the PSTN 290. Similarly, PSTN 290 connects with MSC 280, MSC 280 connects with BSCs 275, and BSCs 275 send BSs 270 to transmit a forward link signal to terminals 100. ).

Although not shown, the MSC 280 may be connected to a communication network based on an IP address. The terminal may be connected to a content providing server that provides restricted use content 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. Stored content may include usage restriction information. When the terminal uses the content within the above usage limits using the printer, the terminal generates detailed information about the use of the content into a message including the content output information, and the generated message is transmitted through the MSC 280. The content is sent to the content provider that provided the content or to the content provider through a communication network connected to the MSC 280.

5 is a flowchart illustrating 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. 5.

First, the terminal accesses the server of the content provider and downloads the corresponding content (S110). At this time, the content includes identification information of the content and usage restriction information in which usage is set in a restricted range. The content provider may include the use notification generation information, which is information that can be notified about the use of the content through the content server, or transmit the information to the terminal in parallel with the download of the content. Content whose use is restricted may include usage restriction information as to whether the content is restricted use content. Such content includes information that, when the terminal uses the content, such as outputting the content, may cause the terminal to drive a function that restricts further use of the content. For example, when the content is a document, the content may be generated so as not to be additionally printed or to have a function of deleting a print menu of the content. The content may include usage notification generation information. The use notification generation information of the content includes a communication address (for example, a telephone number or an IP (internet protocol address) of the server to be transmitted.

It may be determined whether the content is content restricted for use, and if the content includes usage restriction information, the content related to receiving the content may be stored (S120). When the content received by the terminal is restricted use content, the terminal may separately record and store received information of the corresponding content. The reception information of the content may be generated by using the use notification generation information of the content when the content is downloaded. That is, the terminal may record the server storing the content and information about the content. However, step S120 may be omitted as optional depending on the functional configuration of the terminal.

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

When outputting the corresponding content to the printer, the terminal outputs the content to the printer, generates a message including the content output information, and sends the generated message to the content server (S140). The content output information may include information such as whether the content is output, whether the output is successful, the size of the output content, the output date and time, the output format, and the like. When the content is output through the terminal, the terminal may transmit the content output information and the usage notification information to a server receiving the content or a content provider providing the content.

When the message is sent, the usage notification generation information received in the content receiving step may be used.

The content provider may confirm whether the use of the content is restricted by receiving the message including the identification information of the content and the content output information.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the technical spirit of the present invention for those skilled in the art to which the present invention pertains. It is not limited by the accompanying drawings. In addition, the above-described embodiments may be configured by selectively combining all or part of the embodiments so that various modifications may be made.
