Özet
In this paper, we explore the issues in policy-based approaches for Quality of Service (QoS) support in Beyond 3G (3G+) mobile networks. QoS support in mobile environments per-user and per-service is a formidable task. Third Generation Project Partnership (3GPP) puts emphasis on a uniform QoS policy management (definition, control, and enforcement) and Common Open Policy Service (COPS) is specified for policy signalling. We show that the policy-based QoS approach is a promising solution to address QoS issue in 4G (a.k.a. 3G +) networks. That is, end-to-end QoS policy approach enables finer-grained service and user differentiation, leading to better subscription-tiering management. © 2005 IEEE.
