摘要： A method is disclosed for efficiently receiving Electronic Service Guide (ESG) data for a Digital Video Broadcasting-Handheld (DVB-H) broadcast service in a DVB-H reception terminal. When ESG data to which session partitioning rules are applied is received in a multiple-stream mode, session-by-session rules are detected. On the basis of the rules, sessions in which actual ESG data is carried are classified by roles required to provide the broadcast service. The associated ESG data from the sessions is acquired and stored. Since ESG data can be efficiently received by providing detailed guidelines for receiving the ESG data based on a session partitioning rule, a reception scheme of the DVB-H reception terminal can be significantly improved.

摘要： A home network system for supporting continuity of data transfer destined to a mobile station (MS1) when the mobile station moves between wireless nodes (12,13), comprising a server (14) for storing multimedia data and a network (11) connecting the server to the mobile station (MS1) via the wireless nodes. A first wireless node (12), while transferring predetermined data from the server to the mobile station (MS1), senses that a connection with the mobile station is cut off. The predetermined data to be transferred to the mobile station is then buffered in one or more of the wireless nodes (13,...) at a time point of disconnection with the mobile station, and the first wireless node (12) maintains a connection with the server (14). A second wireless node (13) in the home network system establishes a connection with the mobile station (now MS1') and, in response a data transfer request from the mobile station, provides the buffered data to the MS.

摘要： A method and apparatus for supporting mobility in a mobile broadcasting system in which Electronic Service Guide (ESG) discovery is required. The mobility support is classified into three ways. The first way is to provide roaming information for a local IPDC operator having a roaming partner among local IPDC operators. In the second way, a terminal transmits a query message for requesting transmission of information on a particular local IPDC operator, and receives information on the particular local IPDC operator in response thereto. The third way is to provide the terminal with type information of an ESG, an access type of which is classified according to provision of a roaming service. The roaming information, the information on the particular local IPDC operator and the type information of the ESG, which are provided to the terminal from the mobile broadcasting system, can be provided in an ESG bootstrap level.
