摘要：
The optimal radio resource management (RRM) design is formulated as a Semi-Markov Decision Process optimization problem in this research. The stationary optimal call admission control policy, which adopts a hybrid handoff scheme, is determined by solving a set of linear programming equations under users' QoS constraints. The call admission control policy can choose actions of hard- or soft-handoff or simply rejecting the request, depending on the traffic conditions and QoS metrics. The performance is analyzed via simulation and compared with those of the noncontrolled scheme and the fixed RRM scheme. Simulations are conducted by OPNET to study the performance under different traffic conditions.
