The analysis shows that there is a close relationship between the number of handoffs and gos , and ics can reduce the number of handoffs and unsuccessful probability of the calls 分析结果表明,切换次数与系统gos间存在着密切关系,而ics能有效地降低呼叫切换次数和呼叫失败概率。
Based on bidirectional call - overflow scheme , the author then analyzes the velocity threshold and the maximum mobile velocity ' s influence on the system gos . that is , when the teletraffic is in a certain range , both increasing the velocity threshold and decreasing the maximum velocity can reduce the unsuccessful probability of calls 在双向呼叫溢出方案的基础上,作者分析了速度门限和移动台最高速度对系统gos的影响,即当呼叫流量在一定范围内时,提高速度门限和降低移动台的最高速度均能减小呼叫的失败概率。
Compared with the blocking of new calls , the users are more dissatisfied with the existing call interrupt . so the handoff calls should have higher priority , which is ensured by assigning the guard channels in the hcs . however , the introduction of guard channels will have quite different effects on blocking probability and handoff failure probability 与新呼叫阻塞相比,用户更不能容忍对已有呼叫的中断,因此可通过在第vi页西南交通大学博士研究生学瞅文hcs中设置保护信道来保证切换用户更高的接入优先权,但保护信道的引入会对呼叫阻塞概率和切换失败概率产生截然不同的影响。
According to similar ft3 frame format and its checkout mode of dnp data link layer , the relationship between fer ( frame error rate ) and ber ( bit error rate ) , frame length is deduced . the computation formulas of average transmission times and repeat transmission times guaranteeing the correct transmission of telecontrol information are given as well 根据dnp3 . 0规约数据链路层类ft3帧及其校验方式,推导出帧传输失败概率(误帧率)与通道误比特率和帧长的关系,同时给出平均传输次数和重复传输次数的计算公式。
