HEADER COMPRESSION/DECOMPRESSION DEVICE AND HEADER COMPRESSION/DECOMPRESSION METHOD

摘要

A header compression/decompression device improving the throughput of the entire multi-layer protocol stack in the network node. In this device, an encoding section (106) compresses the multi-layer header information contained in the protocol data unit on the multi-layer protocol stack (101). A session context ID manager (112) integrates information on the multi-layer header information compression by the encoding section (106) and, for example, generates a session context ID (401) including information for identifying the method for compressing the multi-layer header information.
