摘要： 分析了考虑切换优先并采用预留保护信道法的无线系统的性能,提出利用一个综合阻塞率和掉线率这两个性能指标的系统服务等级变量作为系统服务质量的指标.分析结果表明,利用服务等级值可以在阻塞率和掉线率之间达成比较好的折衷,并且可以用来确定最佳的预留保护信道数和系统可以容纳的最大负载.

关键词: 阻塞率, 掉线率, 呼叫接入控制, 保护信道, 马尔可夫链, 服务等级

Abstract: This paper analyzes the performance of reservation guard channel with handoff priority. For blocking rate and dropping rate are two discrepant variables, we propose a variable of service grade that integrates the two variables as metrics for system service quality. The result shows that the service grade can trade off well between the blocking rate and dropping rate, and can also decide the optimal number of reservation guard channel and the system maximum load.

Key words: call admission control, Markov chain, grade of service, guard channel, blocking rate, dropping rate
