Abstract: PURPOSE: A method for configuring packets in an international mobile telecommunications-2000(IMT-2000) base station system is provided to divide frames for being communicated between internal processors of the base station system into packet units, and to configure a status field expressing whether a present packet is a final packet divided from a specific frame, then to configure headers of the packets with a length field expressing the entire length of the packets, used when the packets are reassembled in a receiving terminal. CONSTITUTION: A base station system divides the entire size of a dual port RAM(DPRAM) into the regular size to configure blocks, and divides each block into status fields, length fields, and packet data fields(ST11,ST12). The base station system adds a destination address to a frame for being transmitted to other processor from an optional processor in a base station, and divides the frame with the length of the packet data fields(ST13). The base station system checks whether divided packet data is final packet data of the frame. If not, the base station system displays that the divided packet data is not the final packet data, in a status field of a next usable block. If the packet data is the final packet data, the base station system displays that the packet data is the final packet data, in the status field of the next usable block(ST14,ST15,ST18). The base station system records the length of available packet data in a length field of a block relating to the displayed status field, and records the packet data in a packet data field of the block(ST16). The base station system informs a direct memory access controller that transmission-ready packets are registered in the block, to transmit the packets(ST17).
