Description
Summary:B3G or 4G systems present different Radio Access Technologies (RAT). These networks are interconnected to improve spectral efficiency, extend service ranges and provide seamless mobility for multi-RAT mobile users. The seamless mobility refers to the network capability of providing continuous services when a mobile user is crossing different RATs. Heterogeneous networks will be seamlessly integrated in one "common" access network, enabling users' mobility with continuous services. This paper analyzes the performance of a new solution of radio resource management for vertical handover UMTS /WiMAX. Our solution is based on load balancing strategy The proposed policy is based on a decision criterion related to call service quality in order to calculate a load factor. The performance analysis, compared to existing approaches for such VHO vision, show that our proposed solution presents lower packet loss rate, lower handover latency and a reduced call blocking probability.
