Abstract
A method for communication in IPv6 networks is provided. In this method, first, a destination node in communication is notified about an association relation between a home address (HoA) index and an HoA. Then, in a packet, an HoA option and a Type-2 routing header are substituted by an HoA index option or a binding index extension header carrying the HoA index according to the association relation stored in the destination node. Further, a system corresponding to the above method is also provided. Through the present invention, an overhead of a mobile IPv6 packet is effectively reduced. Besides, the HoA index is simple in content and is not relevant to any privacy parameter in content, thus ensuring the security of communication.
Claims18
A mobile node (MN) in a system for communication in mobile IPv6 networks, comprising:
- a binding update (BU) module, adapted to send a BU message to a destination node, wherein the BU message comprises an home address (HoA) and an HoA index corresponding to the HoA;
- and
- a first packet sending module, adapted to send a packet to the destination node, wherein when the MN is in a foreign link, the module carries the HoA index corresponding to the HoA in the packet to be sent, and removes the HoA from the packet.
A method for communication in mobile IPv6 networks, comprising:
- notifying a destination node in communication of an association relation between a home address (HoA) and an HoA index of a mobile node (MN);
- and
- carrying the HoA index in an interactive packet between the MN and the destination node, and then obtaining, by the MN or the destination node as a receiving end of the packet, the HoA through the HoA index.
A communication node (CN) in a system for communication in mobile IPv6 networks, comprising:
- a first association storage module, adapted to receive and store an association relation between an HoA and an HoA index notified by a mobile node (MN);
- and
- a second packet sending module, adapted to send a packet, wherein when sending a packet to the MN located at a foreign link, the module carries the HoA index corresponding to the HoA of the MN in the packet, and removes the HoA from the packet.
A home agent (HA) in a system for communication in mobile IPv6 networks, comprising:
- a second association storage module, adapted to store an association relation between an home address (HoA) and an HoA index notified by a mobile node (MN);
- and
- a third packet processing module, adapted to receive a packet carrying the HoA index, and obtain the HoA corresponding to the HoA index.
A system for communication in mobile IPv6 networks, comprising:
- a mobile node (MN), adapted to notify a destination node of an association relation between an home address (HoA) and an HoA index thereof, wherein when the MN is in a foreign link, the HoA index corresponding to the HoA is carried in a packet to be sent;
- and
- a destination node, adapted to receive and store the association relation between the HoA and the HoA index of the MN, receive the packet carrying the HoA index, and obtain the corresponding HoA according to the HoA index.
