开放无线接入网（O-RAN）定义了未来6 G无线网络的新兴蜂窝无线接入网（RAN）架构，强调开放性和智能性，这被认为是未来6 G无线网络的基础。虽然RAN固有的复杂性和灵活性带来了许多新的研究问题，但由于缺乏端到端的、完全开发的平台，因此开发解决方案的进展受到阻碍，这些平台可以帮助在现实环境中实现用例。这推动了无线社区可用的开源框架的形成。然而，利用各种基于软件的技术的专用平台和解决方案的快速发展往往留下关于框架中组件之间的互操作性和交互的问题。本文介绍了如何构建一个软件定义无线电测试平台，该平台具有开源5G系统，可以通过标准接口与O-RAN架构的近实时（近RT）RAN智能控制器（RIC）进行交互。我们专注于O-RAN E2接口交互，并概述了实现具有E2功能的RAN系统的过程。我们演示了两个xApp在测试平台上的工作，详细的E2消息交换程序及其在控制下一代RAN中的作用。
Open RAN (O-RAN) defines an emerging cellular radio access network (RAN) architecture for future 6G wireless networks, emphasizing openness and intelligence which are considered the foundations of future 6G wireless networks. While the inherent complexity and flexibility of the RAN give rise to many new research problems, progress in developing solutions is hampered due to the lack of end-to-end, fully developed platforms that can help in pursuing use cases in realistic environments. This has motivated the formation of open-source frameworks available to the wireless community. However, the rapid evolution of dedicated platforms and solutions utilizing various software-based technologies often leaves questions regarding the interoperability and interactions between the components in the framework. This article shows how to build a software-defined radio testbed featuring an open-source 5G system that can interact with the near-real-time (near-RT) RAN intelligent controller (RIC) of the O-RAN architecture through standard interfaces. We focus on the O-RAN E2 interface interactions and outline the procedure to enable a RAN system with E2 capabilities. We demonstrate the working of two xApps on the testbed with detailed E2 message exchange procedures and their role in controlling next-generation RANs.
