摘　　要：基于统计复用方式的无线业务信道接入控制算法对于提高电力无线通信网络容量、链路利用率以及系统稳定等方面至关重要。针对现有迭代业务接入控制算法采用一次判别,可能造成已被系统接纳的部分业务信道不足的问题,提出了通过设置后缓存方式,在静默期多次判别的改进方案,基于流模型对该改进算法进行了理论分析和仿真。仿真结果表明,改进后的算法明显降低了原算法在多业务同时突发时的数据丢失率。Wireless traffic channel access control algorithm based on statistical multiplexing is very important for improving the capacity of wireless communication network, link utilization and system stability.According to the one-time-discriminate used on existing iteration traffic access control algorithm, which may cause the shortage of the traffic channel been accepted by system acceptance, the improved scheme been analyzed and simulated by flow model is put forward by repeatedly discrimination in silent period with setting the cache. The simulation results show that the improved algorithm obviously reduces the loss probability of data caused by multiservice simultaneous burst.
