  • Patent number: 7995552
    Abstract: An encoding method and apparatus for a DCH (Dedicated Channel) encoder and a DSCH (Downlink Shared Channel) encoder in a transmitter for a mobile communication system including the DCH encoder for encoding k bits among 10 input TFCI (Transport Format Combination Indicator) bits and the DSCH encoder for encoding remaining (10?k) bits among the input TFCI bits. The method comprises generating, by the DCH encoder, a first coded bit stream by encoding the k input bits into 32 bits, and outputting a (3k+1)-bit stream by puncturing the first coded bit stream according to a specific mask pattern corresponding to the k value; and generating, by the DSCH encoder, a second coded bit stream by encoding the (10?k) input bits into 32 bits, and outputting a {3*(10?k)+1}-bit stream by puncturing the second coded bit stream according to a specific mask pattern corresponding to the (10?k) value.

  • Patent number: 7953391
    Abstract: Disclosed are a method and a system for mutual inclusive authentication between a service provider, a terminal and a user identity module. The authentication system is configured in a structure that can interact with a public key infrastructure of the current network security environment and can be independently used in a specific network system. The inclusive authentication method is divided into public key authentication and symmetric key authentication. Mutual authentication can be made between a service provider, a terminal and a user identity module using any of the two authentication schemes. Then a user can access content on any terminal device using the content license based on the user's identity.

  • Publication number: 20110035285
    Abstract: A method for setting a number of advertisements desired to be received from an advertisement server when a user requests an advertising service. In particular, if the user sets the desired number of advertisements through an advertisement application, the advertisement application provides an advertisement engine with an advertisement request including the set number of advertisements. An advertisement engine determines if the number of advertisements stored in a memory of the terminal is greater than or equal to the requested number of advertisements. If the number of advertisements stored in the memory of the terminal is less than the requested number of advertisements, the advertisement engine makes a request for advertisements to an advertisement server and receives the advertisements. Therefore, the advertisement application can receive the requested number of advertisements from the advertisement engine, so that it is possible to provide the user with a more differentiated MobAd service.

  • Publication number: 20100262826
    Abstract: A first terminal subscribes to at least one service using a service guide in which information necessary for reception of each service is stored, and sends the service guide and an identifier (ID) of the subscribed service to a smartcard. The smartcard stores the service guide and the ID of the subscribed service, and sends the service guide and the ID of the subscribed service to a second terminal through a response message to a request message used for acquiring TBK information, received from the second terminal. The second terminal receives the response message by sending the request message to the smartcard, acquires TBK information corresponding to a service that the second terminal intends to play back, from the service guide depending on the subscribed service's ID included in the response message, and acquires the TBK by performing an authentication process using the TBK information.
