Document Type and Number:
WIPO Patent Application WO/2006/056122
Kind Code:
A1
Abstract:
A method for rapidly resuming context of compression and decompression, in order to solve the problem related art that can not rapidly resume the context so as to cause in lower success ratio of decompression when compressor side occurs a great amount of lost packets; the method includes, automatically sending the status indication information of lost packet when the data compression side detects the data packet being lost; said data compression side initializes the context of the compressor again in accordance with said status indication information, and sending a packet carrying the context information to corresponding data decompression side; the data decompression side updates the context of the de-compressor using the context information of said packet, making the context of both compressor side and de-compressor side to synchronize.
