    摘要： A roaming service method in a mobile broadcasting system and a system thereof are provided. A terminal receives a service guide from a corresponding visited service provider (Visited SP) when the terminal moves to a roaming area. The terminal transmits a roaming request message for requesting a purchase item allowable for individual services to a home service provider (Home SP) based on the received service guide. Upon receipt of the roaming request message, the Home SP negotiates roaming availability and allowable scope for each individual service with the Visited SP where the terminal is located, based on the roaming request message. The Home SP transmits the roaming availability and allowable scope for the individual service, negotiated with the Visited SP, to the terminal.

    摘要： A terminal and method for receiving a broadcast service by the terminal in a broadcast system are provided. The method includes performing a registration procedure for subscription and reception of the broadcast service through a Browser And Content Mobile Broadcast (BSCAST) Subscription Management (BSM) responsible for managing subscription information; receiving a Long Term Key Message (LTKM), including key information for encryption of the broadcast service, generated from the BSM; receiving a completed Short Term Key Message (STKM), the completed STKM being generated by performing Message Authentication Code (MAC) processing on a partially created STKM; receiving, from a Broadcast Service Distribution/Adaptation (BSD/A) which is responsible for transmitting the broadcast service, an encrypted broadcast service which is encrypted by a Traffic Encryption Key (TEK) for deciphering the broadcast service; and deciphering the encrypted broadcast service by the TEK obtained using the LTKM and the completed STKM.

    摘要： 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.
