DATA PROCESS LOAD PREVENTION METHOD AND DEVICE IN MULTIMEDIA SATELLITE COMMUNICATION SYSTEM

摘要

PURPOSE: A data process load prevention method and a device in multimedia satellite communication system are provided to prevent data process load by assigning service information when a station requests access. CONSTITUTION: A common service information transmission step transmits a TS(Transport Stream) packet of data which includes CDMA(Code Division Multiple Access) code used in initial connection, frequency data, and common PID(Packet IDentifier). An access request receiving step receives access control message including subscriber ID from a station. A station ID assigning step assigns usable PID corresponding to subscriber's ID when the subscriber is determined to be legal. A transmission path storing step stores information through a transmission data process path established in correspondence with assigned IP. A station ID transmission step generates TS packet data including assigned station ID, and transmits the TS packet data to an access requested station. A data receiving step receives traffic data or generated control message data. A transmission path switching step selects switching to a transmission data processor unit corresponding to IP information of received data. A data transmission process step transmits data through established transmission process path.
