The 3G wireless systems can be characterized by aggregate bit rates in the range of Mbps quality-of-service QoS support for interactive multimedia services global mobility service portability enhanced ubiquity and larger user capacity and coverage. All digital entirely packet-switched radio networks involving hybrid networking and access technologies are envisioned in 3G systems. In such systems radio resource management RRM plays a major role in the provision of QoS and efficient utilization of scarce radio resources. With the required support for multimedia services to multiple users over diverse wireless networks and the ever-increasing demand for high-quality wireless services the need for effective and efficient RRM techniques becomes more important than ever. The addition of efficient packet data channels in both forward and reverse directions and QoS support in 3G standards lead to a more flexible network but at the same time increase the complexity of determining the optimal allocation of resources .
