摘要:

流量学习和预测是电信网络性能评估的核心,在有线宽带网络中引起了广泛的关注。现在,受益于蜂窝网络中的大数据,可以使分析进一步进入应用层面。在本文中,我们首先从蜂窝网络运营商收集了大量的应用级流量数据。然后,借助流量“大数据”,对蜂窝网络流量建模和预测框架进行了全面的研究。我们的研究结果表明,普遍存在的一些交通统计建模特性,包括在时域上的ALPHA稳定的建模特性和在空间域的稀疏性。同时,研究结果也表明了不同服务类型的应用程序的独特性所产生的差异。在此基础上,提出了一种新的流量预测框架,并提出了一种基于字典学习的交替方向方法来解决该问题,通过大量的仿真实验验证了该框架的预测精度和鲁棒性。

英文摘要:

Traffic learning and prediction is at the heart of the evaluation of the performance of telecommunications networks and attracts a lot of attention in wired broadband networks. Now, benefiting from the big data in cellular networks, it becomes possible to make the analyses one step further into the application level. In this paper, we firstly collect a significant amount of application-level traffic data from cellular network operators. Afterwards, with the aid of the traffic "big data", we make a comprehensive study over the modeling and prediction framework of cellular network traffic. Our results solidly demonstrate that there universally exist some traffic statistical modeling characteristics, including ALPHA-stable modeled property in the temporal domain and the sparsity in the spatial domain. Meanwhile, the results also demonstrate the distinctions originated from the uniqueness of different service types of applications. Furthermore, we propose a new traffic prediction framework to encompass and explore these aforementioned characteristics and then develop a dictionary learning-based alternating direction method to solve it. Besides, we validate the prediction accuracy improvement and the robustness of the proposed framework through extensive simulation results.
