该方案还采用了动态阈值的保护信道策略，保证了新呼叫和切换呼叫之间的优先级和公平性。
Guard Channel scheme based on dynamic thresholds is used in the scheme. It guarantees the priority and fairness between new calls and handoff calls.
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。
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.
