  • Publication number: 20060268820
    Abstract: An IPv6 mobile node is described herein that compresses a packet such that the compressed packet which includes an outer IP header, a compressed inner IP header and data can be sent within a bi-directional tunnel via one or more IP networks to a remote device (e.g., home agent, correspondent node, another mobile node). The IPv6 mobile node can also compress the outer IP header in the packet in addition to compressing the inner IP header if it is located in a wireless access network. The remote device can compress the packet in the same manner and send it to the IPv6 mobile node.
