The invention is a system and method for synchronizing the transmission of
compressed headers in data packets between a transmitter and a receiver
having a preferred wireless application which is an improvement of
RFC2508. In a system having a transmitter transmitting a plurality of
packets each containing a header to a receiver, a method of synchronizing
the transmission of compressed headers between the transmitter and
receiver in accordance with the invention includes transmitting a current
packet from the transmitter to the receiver containing information that
the transmitter is prepared to send subsequently transmitted packets in
which the headers therein are to be compressed in comparison to the
header contained in the current packet; and transmitting from the
receiver to the transmitter an acknowledgment packet that the receiver
has received the current packet.
