Method and device for decoding by using window-based least significant bits in robust header compression

摘要: The present invention relates to communication technologies, and provides a decompression method for network, in which such fields as an SN are compressed by using ROHC scheme, so that the compression efficiency is increased. uses WLSB algorithm compress some change regularly, decodes decompressor's context through transmitting low significant bits these fields. In order avoid inefficient ergodic incorrect direct replacing bits, selects, based on mathematical characteristics of definition interpretation intervals, decode determined received k while high jointly local storage information bits. Its decoding can be used SN, TS IP-ID compression.
