Patent ID: 8189594

Claim:
A method of controlling header compression in wireless communication for a wireless communication system including a transmitter that controls header compression states of data segments addressed to a wireless terminal into a compressed or uncompressed state and that transmits the data segments, and a wireless base station that receives the data segments addressed from the transmitter to the wireless terminal and that transmits the data segments to the wireless terminal, wherein the wireless terminal decodes header-compressed data segments transmitted from the wireless base station, based on a received header-uncompressed data segment, the method comprising: providing, with the wireless base station, a missing notification to the transmitter when detecting the missing of a data segment from the transmitter; and determining, at the transmitter, a header compression state of the missing data segment when receiving the missing notification; and controlling, at the transmitter, a header compression state of a subsequent data segment addressed to the wireless terminal into an uncompressed state when the header compression state of the missing data segment is an uncompressed state.
