The present document provides a method and system for updating a reorder depth in robust header compression. The method comprises: when determining a reorder occurs in data packets, a decompressor estimating the reorder situation, and determining whether a more robust reorder processing policy needs to be used according to the reorder situation; if it needs not to be used, maintaining a reorder depth value at the decompressor side; if it needs to be used, updating the reorder depth value at the decompressor side to a greater value, and transmitting a feedback packet carrying the updated reorder depth value to a compressor; and after receiving the feedback packet, the compressor updating the reorder depth value at the compressor side according to the reorder depth value in the feedback packet. The method can effectively update the reorder depth according to the reorder situation, which not only effectively ensures the robustness of the current compression policy, but also ensures the compression efficiency. |
