Patent ID: 7623549

Claim:
A method of transmitting a packet within a telecommunication system that transmits or receives telecommunication data, wherein the system includes a header compression layer at a transmitting side that transmits a full header packet having all header information or a compressed header packet having compressed header information with respect to a packet stream and a header compression layer at a receiving side that decodes the compressed header information using the full header information, the method comprising: generating a full header packet at the header compression layer at the transmitting side; repeatedly transmitting the full header packet through a data link layer within a lower layer at the transmitting side; receiving, from a data link layer within a lower layer of the transmitting side, a transmission result generated by the data link layer of the transmitting side, wherein the transmission result is associated with the transmission of the full header packet; processing the transmission result to determine whether at least one full header packet has been successfully transmitted; and generating and thereafter transmitting a compressed header packet if it is determined that at least one full header packet has been successfully transmitted.
