Problems solved by technology

This causes two problems: first, it is not easy to change the IP address of the AT; second, the router needs to be updated with a new address in some way for the same Mobile AT packets can now be routed differently
However, in order to establish a PMIP session, security issues must be addressed

Abstract

This application relates to a packet forwarding method for Proxy Mobile IP. According to various embodiments, comprising, when establishing a wireless communication session between a mobile access terminal (AT) and a first IP gateway (IPGW), registering the mobile AT and the first IPGW with a home agent (HA). In various embodiments, the method additionally includes transferring context information about the mobile AT from the first IPGW to the second IPGW when the mobile AT moves from a first access network to a second access network and the proxy mobile security key obtained through the first IPGW.

Description

[0001] This application is a divisional application of the patent application filed on October 9, 2007 with the application number 200780037686.X and the title of the invention "packet forwarding method for agent mobile IP". technical field [0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0003] This summary relates to packet routing for a mobile access terminal moving between two access nodes. Background technique [0004] In a wired IP network, clients and servers use each other's Internet Protocol (IP) addresses to identify and communicate with each other. Each IP packet carries the sender's IP address (source IP address) and the recipient's IP address (destination IP address). Media routers and switches look at source / destination IP addresses to route packets from source to destination. Methods of routing packets based on the IP addresses in the packets are known. Typica...
