| 摘 要： | 以混合信道分配技术为研究对象，在建立拟生灭过程的教学模型过程中选择切换保留混合优先级算法，然后通过模型平稳分布的求解得出性能指标的教学表达式，通过仿真对其性能进行比较．结果表明混合信道分配略差于动态信道分配，但明显优于固定信道分配．

| Abstract: | Hybrid Channel Allocation(HCA)which is a compromise has the virtue of Fixed Channel Allocation (FCA)and Dynamic Channel Allocation(DCA). In order to improve the efficiency of channel utilization,this article constructs models of the three channel allocation strategies based on Quasi-Birth-and-Death processes (QBD)during which we select the hybrid priority handoff reservation algorithm. We derive the mathematical expressions of key performance indicators such as call blocking probability. Simulation and comp... |
