Admission control policy based on decision theory for multiple class services in CDMA
基于决策理论的CDMA网络中多类业务的准入控制策略

Admission control is one of the key policies to guarantee Quality of Service (QoS) in cellular CDMA networks. In this paper, an optimal Call Admisition Control (CAC) scheme based on Semi-Markov Decision Processes (SMDP) is presented to support multiple class services for QoS wireless networks. Linear programming formulation is used to find the optimal solution, which maximizes the channel utilization while guaranteeing requirements of QoS constraints. In addition, weighted fair blocking constraints are used to implement flexible QoS requirements. The numerical results show that the performance of this scheme is better than that of threshold based scheme.
