Pricing-Enabled QoS for UMTS/WLAN Network

In this paper we propose a pricing-enabled QoS for the hybrid UMTS/WLAN network. The proposed methodology is an integration of usage-based, non usage-based, static, and dynamic pricing schemes and DiffServ (Differentiated Services). We propose the utility function and cost function for our needs, and the pricing mechanism is based on differentiated service classes. By the affection of price, a user could express the service class he actually needs and expects. Network resources could be allocated appropriately to each service class avoiding inappropriate allocation and wastage, and thus meet the QoS requirement.
