METHOD AND SYSTEM FOR TRANSMITTING AND RECEIVING PACKET

摘要

PROBLEM TO BE SOLVED: To provide a system and method for synchronizing transmission of compressed headers in data packets between a transmitter and a receiver having a preferred wireless application which is an improvement of RFC2508. SOLUTION: In a system having a transmitter transmitting a plurality of packets each containing a header to a receiver, a method with which synchronization of the transmission of the compressed headers between the transmitter and the receiver is established includes a step in which the transmitter transmits a current packet from the transmitter to the receiver containing information indicating that the transmitter is prepared to send subsequently transmitted packets having the headers to be compressed in comparison with the header contained in the current packet and a step in which the receiver transmits an acknowledgement packet indicating that the receiver has received the current packet from the receiver to the transmitter.
