【摘要】 为挖掘除时延界和时延界违反概率的时延相关的QoS(Quality of Service)准则，针对5G网络中突发型时延敏感业务，提出了一种新的统计时延QoS度量方法——超时的平均停时。基于鞅论，研究了平均停时的分析框架，考虑到功率分配和免授权接入对平均停时QoS的影响，研究了ALOHA随机接入网络中每个终端的超时平均停时。最后，提出了一种新的高能效且提供平均停时QoS保障的ALOHA接入算法。仿真结果表明，算法满足终端的平均停时约束，平滑了时延过程的突发性。更多还原

【Abstract】 In order to explore the delay-related QoS(Quality of Service) criteria and to the delay bound and the probability of delay bound violation, a novel delay-QoS metric, time-out average stopping time, is proposed for bursty time-delay sensitive services in 5G networks.The analytical framework of mean stopping time based on martingale theory is studied. Considering the mutual effect between the power allocation and unauthorized access on average stopping time QoS, the timeout average stopping time of each terminal is investigated in ALOHA random access network. Finally, an ALOHA access algorithm with novel energy-efficient and average stopping time QoS guarantee is proposed. Simulation results demonstrate that the proposed algorithm can satisfy the constraint of the average stop time of the terminal and smooth the bursty for the delay process.更多还原
