ABSTRACT:
A method of providing Mobile IP functionality for a non Mobile IP capable mobile node by a switching device by proxy, wherein a first address (HOA) and a second address (SA) are being allocated to said mobile node (MN), said method comprising the steps of: utilizing said first address (HOA) for non Mobile IP based communication legs by routing data to a home agent (HA) of a home network of said mobile node (MN); discovering an address of said home agent (HA) by said switching device; advertising said second address (SA) as care-of-address (CA) with respect to said first address (HOA) by said switching device to said home agent (HA); and utilizing said second address (SA) for Mobile IP based communication legs by routing data to said switching device (GGSN/MIP PROXY).
