Patent ID: 8856820

Claim:
A mobile communication terminal comprising: a data judgment module which judges whether to restrict digital content by comparing content information included in a packet of the digital content with viewing restriction information; and a control unit which controls whether to display the digital content in accordance with a result of the judgment of the data judgment module, a packet generation unit which generates a response packet to be transmitted to the provider of the digital content; and a packet transmission unit which transmits the generated response packet to the provider by using information about the provider included in the packet received through the receiving unit; wherein the data judgment module comprises an information storage unit which stores the viewing restriction information and the viewing restriction information can be changed exclusively by resetting the information storage unit, thereby a user or a user's protector cannot directly change the viewing restriction information, but the viewing restriction information can be changed exclusively by resetting the information storage unit by an after-sales service center or an agency, wherein if the viewing of the digital content is not permitted and the corresponding digital content is fee-based content, the control unit controls the packet generation unit and the packet transmission unit to generate and transmit a response packet to the provider of the corresponding digital content to refuse the downloading of the corresponding digital content.
