An Optimal Authorization Method Based on Integrated AAA Architecure with PANA Mechanism in Heterogeneous Network

To achieve the increasing needed service of solving multi-users' access in heterogeneous network, this paper presents an integrated AAA architecture combined with PANA mechanism, for benefit of masking different link layer access technologies in heterogeneous network environment. Compared with current authorization mechanism, we propose an optimal solution that access network resources are based not only on simple access method to wireless network, but also on roles and attributes end mobile user grants. Finally, this paper gives the demonstration of our proposal.
