Radio resource management (RRM) in the next generation wireless network system will have features and requirements that are quite distinct from current systems, mostly designed for non-heterogeneous and non-shared networks. Such features include radio resource sharing which is considered as one of the main future issues of RRM as network evolves towards 4G Radio resource sharing has an impact on system design in general and on radio resource management in particular. This paper presents a general RRM for 3G and beyond mobile wireless network supporting multi-services, referred to as general call admission control (GCAC). The aim of the proposed GCAC algorithm is to guarantee the required quality of service (QoS) and to maintain higher resource utilization. Simulation results indicate that the proposed GCAC provides higher resource utilization under all load conditions leading in turn to increased revenue. In addition, a higher quality of service for traffic is provided especially when we differentiate between the traffic classes.
