“…In addition, wireless environments are dominated by a quite high rate of customer mobility [3], [17], which needs to cross different technologies, and which requires the support of roaming between those environments. Different technologies have their own accounting mechanisms, which do not allow for an interoperability in most cases [20], [24]. But network providers need an integrated accounting architecture that enables to apply a common accounting process for different technologies in order to reduce configuration and management efforts and costs.…”

“…The key success factor of this scenario is dominated by a successful interoperability between providers in terms of accounting and in support of charging [5], [24]. Initially, forcing a user to sign up with every provider confronted with is not an acceptable solution, since it does restrict the mobility of a user due to administrative boundaries.…”

Accounting for resource and service usage in communication networks forms the basis of network operators' business, and is therefore essential. Within a heterogeneous, multidomain mobile environment of emerging new access technologies, the demand for a distributed accounting infrastructure becomes more relevant. Driven by the analysis of current accounting solutions in Universal Mobile Telecommunications System (UMTS) and Wireless Local Area Networks (WLAN) networks, the newly developed approach presents an integrated accounting architecture based on the Diameter protocol, forming a flexible basis for charging UMTS and WLAN communication services. The system developed is described, discussed and evaluated by a prototypical implementation.

“…On the one hand, the access control to resources exposed from several providers might involve different administrative domains, each applying its own access control policies and adopting different security mechanisms [3]. On the other hand, users might access the resources through service entities operated by a provider that did not directly subscribe to, e.g., occasional access to a WiFi hot-spot during a stop-over in a airport.…”

Efficient Authentication and Authorization of Mobile Users Based on Peer-to-Peer Network Mechanisms

This paper presents a peer-to-peer based authentication and authorization infrastructure to minimize authentication delays when mobile users roam across different wireless networks. The basic idea is to avoid exchanging security information between networks visited by a roaming user and the user's home authentication, authorization, and accounting (AAA) server that is typically located in the home network possibly far away from the visited network. Instead, authentication and authorization of a roaming user shall be supported by an AAA server in the visited network. We propose that the AAA server that is responsible for authentication and authorization in a newly visited network locates the AAA server in the previously visited network and retrieves the required security information from that AAA server. The AAA servers can be organized in a peerto-peer manner and peer-to-peer mechanisms can be applied for searching and transferring security information between them. We propose several mechanisms for quickly locating the previously responsible AAA server in order to decrease authentication delays. The performance of these mechanisms is evaluated by simulations. Real performance measurements show the rather low performance overhead of application level forwarding used in peer-to-peer networks.
