摘要： 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.

摘要： A method and apparatus for eliminating the inefficient use of network bandwidth cause by numerous acknowledgment transmitted by the receiver to the transmitter by providing sparse feedback from the receiver to the transmitter indicating receipt of packets having headers to be used as reference headers. In the invention, upon receipt in the receiver of a packet having a reference header, a feedback is provided to the transmitter indicating receipt of the packet having the reference header. Thereafter, the receiver waits a predetermined period of time before providing another feedback in response to another packet having a reference header. The predetermined period of time allows time for the feedback to be received by the transmitter and for information from the transmitter indicating receipt of the feedback to be received by the receiver.

摘要： The invention is a method and system for compressing a current value into a minimum number of bits for transmission from a compressor to a decompressor. A method in accordance with the invention includes maintaining a series of at least one previous value at the compressor, each previous value having different k least significant bits and which have been transmitted to the decompressor; determining a value of k representing a smallest number of bits which allows successful decompression of the current value at the decompressor using as a reference value any value in the series of at least one previous value; and transmitting the current value from the compressor to the decompressor in compressed form with the k least significant bits of the current value.
