摘　　要：文章在分析2G-ALE建链流程的基础上,建立了平均建链概率和平均建链时间性能指标数学模型,依据此模型分析了信道扫描速率以及引导呼叫的长度对平均建链时间的影响。通过仿真比较了两种信道驻留时间的优化方案,结果表明在差信道条件下适当降低信道扫描速率可以减少平均建链时间。指标模型和仿真分析对于ALE系统的设计优化具有一定的参考意义。The mathematic models of the average probability and time of link successfully established were presented after analyzing the processing procedure in HF 2GALE. The effect of the channel scanning rate and leading call length to average time to establish link was investigated, and two optimization of the channel dwell time also presented. Simulation result shows that slower channel scan rate can achieve shorter average time to establish link.
