User Satisfaction Based CRRM policy for heterogeneous wireless networks

Beyond 3G wireless networks are characterised by the coexistence and cooperation of heterogeneous Radio Access Technologies (RAT), which requires the design of adequate Common Radio Resources Management (CRRM) techniques capable to exploit their varying characteristics and efficiently use their scarce radio resources. In this context, this paper proposes a novel CRRM initial RAT selection algorithm (USaBS - User Satisfaction Based Selection) designed to provide and guarantee users with a pre-established Quality of Service satisfaction level defined according to their contract and service type.
