中文摘要： 海量MTC终端短时间内同步入网时其业务模式将表现出明显的瞬时突发特性。该特性将造成承载网络严重的流量过载或网络拥塞，也使得基于齐次泊松过程和复合泊松过程的流量分析理论难以直接应用且目前尚无一种公认的统计描述方法。“如何描述该瞬时突发性并据此完成承载网络的性能分析及优化设计”成为制约MTC进一步推广应用的瓶颈和亟待解决的突出难题。为适应MTC的业务特性和发展需求，本项目将重点研究海量MTC终端同步入网时其瞬时突发性的统计描述方法，并据此建立MTC专属的流量模型，完成承载网络的性能评估与优化设计，完善MTC流量分析理论。主要研究内容包括：突破有限支撑区间内非独立点过程聚合效应的统计描述，建立MTC专属的队列模型和具有QoS保障的界模型，完成多信道S-ALOHA协议的稳定性分析、稳定化设计和高能效设计，以期为MTC的推广应用提供理论基础和技术支撑。

英文摘要： The concurrent data transmission from massive machine type communications (MTC) devices within a short time period makes the traffic flow of MTC more bursty, which directly causes the well-known congestion problem of MTC and invalidates the traffic models based on Poisson assumption. The researches on the statistical description of this burstiness and the performance analysis and access control of carrier network beyond Poisson assumption are still in very initial step and are rarely reported in state of the art literatures. To tackle these challenges, this project takes the initiatives to discuss some prime issues for MTC traffic engineering beyond Poisson assumption. The major topics include: statistical description and analysis of the superposition of non-independent random sequences of events within finite support range, dedicated traffic models and traffic bounds for MTC, stability analysis and stabilizing techniques for multi-channel slotted aloha, energy efficient design for multi-channel slotted aloha. All these together would help to improve the methodology of traffic engineering for MTC and support the long-term deployment of MTC applications.
