Communication method in mobile IPv6 and mobile IPv6 communication system

Abstract

The core idea of the method is that the method informs association relation between the home address index and the home address to corresponding communication end point (CEP); then using one-to-one correspondence between the home address index and the home address stored in buffered list items at each CEP, the method replaces option of home address and second kind of route head by home address index option or expanded head of binding indexes including carried home address indexes in data packet. The invention also discloses corresponding mobile IPv6 transmission system. The invention can reduce overhead of mobile IPv6 packet head effectively. Since content of home address index is simple and is not correlative to any privacy parameter, thus, the invention makes mobile users possess better security in communication.

Description

technical field

[0001] The invention relates to the technical field of network communication, in particular to the communication technology in the sixth edition of the mobile internet protocol. Background technique

[0002] Mobile Internet Protocol Version 6 (IPv6: Internet Protocol version 6) is a solution to mobility at the network layer. There are three basic network entities in Mobile IPv6: Mobile Node (MN: Mobile Node), Correspondent Node (CN: Correspondent Node) and Home Agent (HA: Home Agent).

[0003] A mobile node can be uniquely identified by its home address (HoA: Home Address). When the mobile node roams to a foreign network, it will generate a care-of address (CoA: Care of Address) in a certain way. The Mobile IPv6 specification requires that when a mobile node moves from one link to another, the ongoing communication using the home address is not interrupted, and the mobility of the node is transparent to the transport layer and other high-level protocols.
