A QoS Index for IP Services to Effectively Support Usage-Based Charging
Dario Di Sorte, Mauro Femminella, Gianluca Reali · IEEE Communications Letters · 2004
The goal of this letter is to present a model to compute a quality-of-service (QoS) index to characterize IP services. Then, we show how such a score may be used in a clear and flexible way for defining advanced usage-based tariff criteria to charge QoS guaranteed network services to address the dynamics of the expected future telecommunications scenario.
