摘要

In a MIPv6 network, a mobile home agent (MHA) in a foreign network (FN) acts as an intermediate node between a mobile node (MN) and a correspondent node (CN) and allocates itself a secondary care-of address (SCoA) different from the care-of address (CoA) of the mobile node (MN), with a one-to-one relationship between the secondary care-of address (SCoA) and the home address (HAddr) of the mobile node.

1. A method of operating an intermediate network entity between a mobile node in a foreign network and a correspondent node, the method comprising:
allocating to the mobile node a care-of address within the foreign network; allocating a secondary care-of address to the intermediate network entity; receiving, in a session between the correspondent node and the mobile node, at least one session packet in a tunnel from a home agent in a home network of the mobile node to the intermediate network entity, wherein the session packet has the secondary care-of address as the destination address; decapsulating the session packet; and forwarding the decapsulated session packet to the mobile node.
