A Multi-Role Authorization Method Used in Heterogeneous Wireless Network

Complex scenarios involving users´ access in different administrative domains of wireless network do require a rather complete network access control mechanism. Thus, we propose an optimal solution where access network resources are based not only on simple access method to wireless network, but also on roles and attributes the end mobile user grants. To solve the problems of traditional centralized management and authorization mechanisms at present, we enhance this optimal solution, which is centralized in the identity authentication management and distributed in the access authorization management, and present new SAML-AVP type transmission message for this mechanism.
