heal.abstract	In this paper the problem of proficient users' network assignment in integrated CDMA/WLAN systems is addressed and a decentralized utility-based Network Selection algorithm aiming at optimizing user's and system's performance while satisfying multiple services' diverse Quality of Service (QoS) requirements is proposed and analyzed. The proposed approach favors the efficient provisioning of both real-time and non-real-time services, by exploiting the benefits emerging from the use of a common utility based optimization framework that provides the flexibility of uniquely modeling heterogeneous QoS prerequisites. Finally, via modeling and simulation it is demonstrated that significant performance improvements concerning both services' QoS requirements fulfillment and system's welfare are achieved through the proposed approach.
