  • 摘要: 海量机器类终端(或MTC终端)同步入网时,其业务呈现瞬时突发性,这使得基于齐次或复合泊松假设的多信道S-ALOHA稳态性能分析办法难以直接应用。该文以第i个随机接入时隙内第j次进行随机接入的用户数Mi(j)作为状态变量,提出了一种沿Mi(j) 的j方向迭代进行多信道S-ALOHA暂态性能分析的办法及其近似形式。该迭代办法可建立第i个随机接入时隙内第j次进行随机接入的用户数与第x个随机接入时隙内新到用户数的直接关系(其中xi),也可给出接入时延概率密度函数、概率分布函数和均值的求解办法。以3GPP MTC业务参考模型进行数值仿真,验证了所提迭代办法及其近似形式的有效性。相关研究可为承载网络的优化设计提供参考。
