Abstract
A system and method for mobility support of a mobile node having a home network in a heterogeneous roaming environment is presented. The method comprises the steps of authenticating the mobile node in a visited network and obtaining an address for the mobile node in the visited network, establishing a security connection between a functional component in the visited network and an agent in the home network, creating a home address for the mobile node, and using the home address to generate a SIP signaling address, a SIP media address, and a non-SIP media address, such that SIP non-media is transmitted using the security connection to the SIP signaling address, SIP media is transmitted using the security connection to the SIP media address, and non-SIP media is transmitted using the security connection to the non-SIP media address.
