摘要: Abstract: The heterogeneous nature of the next generation wireless systems (NGWS) poses many challenges to call admission control algorithm. In this paper, a hierarchical approach joint is proposed for networks. scheme, algorithm will be divided into two; namely, horizontal (HCAC) and vertical (VCAC). This avoid unnecessary signalling processing certain stages that are specific an access network technology. We modify dual threshold bandwidth reservation scheme (DTBR) triple (TTBR) support handoff calls. strong feature it based on complete sharing (CS) overall bandwidth, which believed yield high radio resource utilization while meeting guaranteed quality service (QoS).
