摘　　要：为解决在采用固定占用发送的多通道随机多址系统中存在的负载不均衡问题,提出1种基于负载均衡的接入控制方式.采用平均周期划分的方法对新系统进行理论分析,得到各通道、各优先级及系统的吞吐量数学解析式,并由计算机仿真实验验证其结果.与原有的控制方式进行比较后,系统在新的控制方式下显示出更好的通道负载均衡性及较好吞吐量,适用于系统轻负载及重负载的情况.To solve the load equilibrium in multi-channel random multi-access system, we propsea a control approach based on load equilibrium . In our approach, the average cycle partition method is applied to analyze the new system from theoretical aspects. Thus, the mathematical formulas can be obtained for each channel, each priority and the system thoroughput. As well, the result was verified by the experiments that are simulated by computers. Comparing with the previous control methods, our method has better performance on load equilibrium and throughput. It can show that our method is useful for both light load and heavy load systerrrs.
