| dc.description.abstract (摘要) | 在未來異質網路的整合環境中，QoS的問題益形重要，而以現今的網路環境而言，最有可能的異質網路整合是UMTS與WLAN。在本計畫中，我們將以UMTS與WLAN的異質網路整合環境作為基礎，提出Pricing-Improved QoS的觀念，結合Non usage-based pricing、Usage-based pricing、Static pricing和Dynamic pricing的優點以及DiffServ (Differentiated Services)劃分服務等級(service level)的機制，實際設計出使用者效用函數(utility function)與網路成本函數(cost function)，並以分級訂價方式訂定價格。藉著價格機能，讓使用者表達其對服務等級的需求或期望，並使網路資源適當地分配給各種服務，避免資源浪費或錯置的情形，以符合QoS的需求並提高整體社會福利及增加廠商收益。 | zh_TW |
| dc.description.abstract (摘要) | The issue of QoS is getting more and more important in the future integration of heterogeneous networks, and the most feasible integration is UMTS and WLAN as for present network environment. In our research, we would propose the concept of pricing-improved QoS combined with the advantage of usage-based, non usage-based, static, and dynamic pricing schemes and the mechanism of differentiated service classess of DiffServ (Differentiated Services) based on the integration of UMTS and WLAN. We would propose the utility function and cost function in detail, and price by differentiated service classes. By the affection of price, a user could express the service class he actually needs and expects. Network resources would be allocated appropriately to each service class avoiding the inappropriate allocation and wastage. This would meet the requirement of QoS and improve the providersâ revenue and overall social welfare. | en_US |
