A simple high capacity multiple service solution with controlled QoS for GERAN
Offering multiple services with high spectral efficiency is crucial for 3rd generation cellular systems. Further, for stable system behavior, controlling quality of service (QoS) for offered loads beyond the capacity limit of the systems is required. This paper describes and evaluates a simple, easy-to-plan concept that accomplishes this goal for the GSM/EDGE Radio Access Network (GERAN). Cornerstones of the concept are tight frequency reuse, service-based power setting and power-based admission control. Preliminary results indicate that the proposed solution manages to preserve targeted QoS for a mix of services at excessive traffic loads. Moreover, different operator QoS policies may be realized in a straightforward manner.
