PACKET COMPRESSION SYSTEM, PACKET RESTORATION SYSTEM AND PACKET COMPRESSION METHOD AND PACKET RESTORATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a packet compression system, a packet restoration system, a packet compression method, and a packet restoration method which make efficient transmission of a CODEC signal.;SOLUTION: The packet compression system is provided with: a reception means for receiving at least one uncompressed packet having a header and a payload of a second OSI layer, a header and a payload of a third OSI layer in the payload of the second OSI layer, a header and a payload of a fourth OSI layer in the payload of the third OSI layer, and the CODEC signal in the payload of the fourth OSI layer; a compression means for generating a compressed packet into which at least one CODEC signal is inserted without interposition of the third OSI layer and the fourth OSI layer in the payload of the second OSI layer by deleting the header of the third OSI layer and the header of the fourth OSI layer from the uncompressed packet; and a transmission means for transmitting the compressed packet.;COPYRIGHT: (C)2004,JPO
