Embodiment Construction

[0057] Throughout the drawings, the same reference signs will be used for corresponding or analogous parts.

[0058] The basic idea according to the invention is to "bootstrap" the HMIPv6 traffic of a mobile node for HMIPv6 authentication and authorization based on an AAA infrastructure instead of relying on a complex PKI infrastructure. HMIPv6 bootstrapping is valid for both a mobile node operating in a home network and a mobile node roaming in a visited network, in the former case using the home network AAA infrastructure and in the latter case using the visited The entire AAA infrastructure where the network is linked with the home network.

[0059] Instead of establishing a security association and distributing security keys between the MN and the MAP by employing a public key infrastructure (PKI), it is preferable to perform authentication and authorization of HMIPv6 services based on the AAA infrastructure, for example conveyed as HMIPv6 via the AAA infrastructure HMIPv...

Abstract

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.

Description

technical field [0001] The present invention relates generally to mobile communications, and more particularly to the support of Mobile IP (Internet Protocol) services, and in particular Hierarchical Mobile IP Release 6 services. Background technique [0002] Mobile IP (MIP) enables a Mobile Node (MN) to change its point of attachment to the Internet with minimal service interruption. MIP itself does not provide any specific support for mobility across different administrative domains, which limits the applicability of MIP in large-scale commercial deployments. [0003] The Mobile IP Version 6 (MIPv6) protocol [1] enables nodes to move within the Internet topology while maintaining reachability and ongoing connectivity with communicating nodes. In this case, each mobile node is always identified by its home address, regardless of its current point of attachment to the IPv6 Internet. When away from its home network, a mobile node is also associated with ...
