Abstract

During the last few years, mobile communication networks have experienced a huge evolution. This evolution culminates with the arrival of the fifth generation (5G) of mobile communication networks. As a result, the complexity of network management tasks has been increasing and the need to use automatic management algorithms has been demonstrated. However, many mobile network operators (MNOs) are reluctant to evaluate these algorithms in their networks. To address this issue, in this paper, a modeling approach is proposed. In this sense, the behavior of a commercial network, as it is perceived by user equipments (UEs), has been replicated in a research testbed using a three-step modeling process. The first step consists on performing a measurement campaign in several external networks. The second step is composed of the measurement campaign result analysis and the classification of the results in different types of scenarios. Finally, the third step is related to the application of a modeling algorithm in a research testbed. In order to perform the last step, the use of a method based on a controller is proposed. The modeling process presented in this paper allows to replicate the network behavior from users located in different areas and with different conditions point of view. Moreover, the use of a testbed environment can help to avoid downtime in commercial networks caused by possible algorithm bugs.

遵循基于控制器的方法对UE感知的蜂窝网络性能进行建模

抽象的

在过去的几年中，移动通信网络经历了巨大的发展。随着第五代（5G）移动通信网络的到来，这种发展达到了顶点。结果，网络管理任务的复杂性不断增加，并且已经证明了使用自动管理算法的需求。但是，许多移动网络运营商（MNO）不愿意在其网络中评估这些算法。为了解决这个问题，本文提出了一种建模方法。从这个意义上说，商业网络的行为，如用户设备（UE）所感知，已经使用三步建模过程复制到了研究测试平台中。第一步包括在多个外部网络中进行评估活动。第二步包括测量活动结果分析和不同类型场景中结果的分类。最后，第三步涉及建模算法在研究试验台中的应用。为了执行最后一步，提出了使用基于控制器的方法。本文介绍的建模过程允许从位于不同区域和具有不同条件的角度的用户复制网络行为。此外，使用测试平台环境可以帮助避免可能的算法错误在商业网络中造成的停机。提出了基于控制器的方法的使用。本文介绍的建模过程允许从位于不同区域和具有不同条件的角度的用户复制网络行为。此外，使用测试平台环境可以帮助避免可能的算法错误在商业网络中造成的停机。提出了基于控制器的方法的使用。本文介绍的建模过程允许从位于不同区域和具有不同条件的角度的用户复制网络行为。此外，使用测试平台环境可以帮助避免可能的算法错误在商业网络中造成的停机。
