摘要:
A method of providing a point-to-point multicast service for transmitting data from a network element to a plurality of terminals in a communication system. The method includes transmitting a first message including service available information from the network element to the plurality of terminals, and transmitting a second message including radio bearer information from the network element to the plurality of terminals. The first message includes a pointer to the radio bearer information.

Disclosed is a method and an apparatus for transmitting/receiving mobility information to support the handover and roaming in a digital broadcasting system. The transmission method includes the steps of setting mobility information including information elements for indicating at least one handover/roaming type according to whether or not support of an interactive network is available for handover/roaming; inserting the mobility information into at least one of an ESG regarding broadcasting services, a notification message, and an independent signaling message so that the mobility information is transmitted to at least one terminal; and conducting handover or roaming of the terminal according to the mobility information.
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.

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.

Disclosed is a method for generating a Short Term Key Message (STKM) for protection of a broadcast service being broadcasted to a terminal in a mobile broadcast system. The method includes transmitting, by a Broadcast Service Subscription Management (BSM) for managing subscription information, at least one key information for authentication of the broadcast service to a Broadcast Service Distribution/Adaptation (BSD/A) for transmitting the broadcast service, generating, by the BSD/A, a Traffic Encryption Key (TEK) for deciphering of the broadcast service in the terminal and inserting the TEK into a partially created STKM, and performing, by the BSD/A, Message Authentication Code (MAC) processing on the TEK-inserted STKM using the at least one key information, thereby generating a completed STKM.

摘要:
A terminal apparatus is provided for receiving a broadcast service from a broadcasting system. A receiver receives a notification message from the broadcasting system. A message parser parses the notification message received by the receiver according to a certain format. A controller determines whether the received notification message is a notification message to be used by a user or a notification message to be used by the terminal based on content of the notification message parsed by the message parser, and performs an operation according to the determination result.
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.
