Message forwarding method and device

Abstract

An embodiment of the invention discloses a message forwarding method and device and is applied to mobile IPv6 technology based home agent. The method includes receiving a message sent to a target mobile node from a communication opposite terminal, wherein the target address carried in the message is the home address of the target mobile node in a home network; judging whether the network with the target mobile node is the home network or not; if the network with the target mobile node is not the home network, substituting the home address with a forwarding address for a target address of the message according to the binding relation of the home address and the forwarding address; forwarding the message with the replaced target address to an access router of a network with the target mobile node currently, so as to enable the access router to send the message with the replaced target address to the target mobile terminal according to the target address of the message. By applying the method and device provided by the invention, message forwarding efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of mobile IPv6, in particular to a message forwarding method and device. Background technique [0002] Mobile IPv6 technology is the deep integration of mobile communication technology and IPv6 technology. Mobile IPv6 technology defines Home Agent HA (Home Agent), Access Router AR (Access Router), Correspondent Node CN (Correspondent Node) Node) four functional entities. Among them, the mobile node, as a mobile terminal device, will change the access point, that is, perform network switching, and switch from one link to another. However, during the link switching process, the current communication between the mobile node and the communication peer will be interrupted. The address obtained by the mobile node in the home network is called the home address HoA (HomeAddress), and the address obtained in the foreign network is called the care of address CoA (Care of address). The home agent registration care-o...

AI Technical Summary

Problems solved by technology

[0003] To sum up, the mobile IPv6 technology provides applications with the transparency of the communication entity movement. When the access network of the mobile node changes, the communication peer can still maintain the communication connection with the mobile node through the home address, but the use of the tunnel In this way, packets are sent from the home agent to the access router, and the packets need to be encapsulated and decapsulated at the two endpoints of the tunnel, which makes the forwarding efficiency of the packets low.
