Abstract

When an MN 1 is handed over from an MAGa 2 to an MAGb 3, a network-based IP mobility protocol processor 11 of an LMA 4 transmits header compression information to MAGb 3 while a network-based IP mobility protocol processor 7 of MAGb 3 stores the information into a storage 8. When receiving a packet, LMA 4 and MAGb 3 perform a tunneling process or a compression information process for every tunnelthrough which the packet passes, to perform appropriate compression / extension and routing. In this way, in a network-based IP mobility protocol, even if the MN had moved, the MN or LMA serves as a compressor and decompressor, so that it is possible to save the band for the last one hop, which is the narrowest band.

Description

technical field [0001] The present invention relates to a communication technique using a network-based IP mobility protocol. Background technique [0002] In recent years, in IP layers such as Mobile IPv6 (Internet Protocol Version 6), research and development for mobility support have been eagerly performed. Mobile IP is a protocol in the third network layer of the OSI (Open System Interconnection) reference model established by ISO (International Organization for Standardization). It is a mobile (network / communication medium switching) that hides the client from the upper layer , momentary interruption of communication, etc.) while maintaining communication technology. [0003] In TCP / IP (Transmission Control Protocol / Internet Protocol), which is a communication protocol commonly used in the Internet today, an IP address is an identifier and at the same time indicates a location on the network. Accordingly, when a node connected to a specific network is changed to anoth...
