Patent ID: 7769901

Claim:
An Internet Protocol (IP) headers decompressor node for exchanging IP packets with at least another node over at least one network link in an IP network for fast IP headers compression initialization comprising: a communication module for: managing the at least one network link toward the at least another node; exchanging signaling messages with the at least another node over the at least one network link; and participating in establishment of a session between at least two nodes of the IP network; a decompression context initialization module for initializing at least one portion of a decompression context prior to completion of the establishment of the session between the at least two nodes of the IP network using information from IP packets exchanged with the at least another node prior to completion of the establishment of the session; an application module for using the decompression context to uncompress application related IP packets exchanged with the at least another node; and an IP headers manager for extracting information from a plurality of IP packets used during the establishment of the session; wherein no one of the plurality of IP packets used during the establishment of the session comprises all information needed to initialize the decompression context.
