Abstract
A method and apparatus operable in a system having a transmitter and receiver for reducing the overhead for compressing headers of a plurality of packets that form a transmission unit, wherein the header of each packet includes identification (ID) information identifying the packets as part of the transmission unit. The invention operates by reassembling the packets that form the transmission unit and removing the ID information from the header of each of the packets that form the transmission unit. After removing the ID information from the header of each packets, the headers of the packets are compressed and the packets having the compressed headers are transmitted from the transmitter to a receiver. The receiver upon receiving the packets having the compressed headers, decompresses the compressed headers to obtain the packets that form the transmission unit. New ID information is then regenerated and inserted in the headers of each of the packets that form the transmission unit so as to identify the packets that belong to the same transmission unit.
