A basic feature of the invention is to rely on an AAA infrastructure to "bootstrap" the HMIPv6 service for a mobile node ( 130 ) that "roams" in a visited network or the home network. In accordance with a preferred embodiment of the invention, bootstrapping the HMIPv6 service involves authenticating and authorizing the mobile node ( 130 ) for HMIPv6 service based on an AAA infrastructure. In an important scenario, the mobile node is roaming in a visited network, and the AAA infrastructure ( 110, 120, 122 ) links the visited network with the home network of the mobile node. The invention also supports the possibility of having the MAP ( 125 ) located in the home network or other network than the visited network. The reliance on the AAA infrastructure preferably involves transferring HMIPv6-related information required for authenticating and authorizing the mobile node for HMIPv6 service over the AAA infrastructure.
