A simple QoS service provision framework for beyond 3rd generation scenarios

This paper describes a global quality of service architecture for mobile, audited and accountable environments. Target networks are "Beyond 3rd Generation Networks", where several heterogeneous access networks are available to the user. Providing per user and per service differentiated QoS is a key issue in these networks. The paper proposes an integrated management approach for service and network management in the case of heterogeneous and mobile network access, based on the cooperative association between QoS Brokers and Authentication, Authorization, Accounting and Charging (AAAC) systems.
