摘要
随着 RAN 控制功能的集中化,出现了大量近乎实时的网络优化用例。到目前为止,每个用例都是作为孤立的网络管理功能(在开放 RAN 术语中称为 xApps)来实施和验证的。由于这些 xApps 的完全隔离会导致决策冲突和不稳定性,因此需要全面的冲突缓解措施,才能逐步实现可商业部署的现实功能。在本文中,我们将研究如何协调实施这些用例中的大多数,以创建增强型 RAN 控制平面,同时强调 RAN 中央单元、分组和网络管理决策交互所需的功能。通过分析 O-RAN 架构中存在的差距,我们确定了所需的功能,并提出了一个管理框架。此外,我们还提出了开发此类功能的实施路线图,作为弗劳恩霍夫 FOKUS Open5GCore 工具包的一部分,以此作为参考,说明此类功能如何能够轻松地进行原型开发、验证并与外部算法集成,从而从大量的学术研究中获益。
Towards efficient conflict mitigation in the converged 6G Open RAN control plane
With the centralization of the RAN control functionality, a very large number of near real-time network optimization use cases have emerged. Until now, each of them has been implemented and validated as isolated network management functions, named xApps in Open RAN terminology. To be able to progress towards realistic, commercially deployable functionality, comprehensive conflict mitigation is needed, because the complete isolation of these xApps would result in conflicting decisions and instability. In this article, we study how the majority of these use cases can be implemented harmoniously, to create an enhanced RAN control plane, underlining the functionality required from the central units of the RAN, the grouping, and the interaction of the network management decision. Analyzing the gap existing in the O-RAN architecture, we identify the functionality needed and propose a management framework. Furthermore, we present an implementation roadmap for the development of such functionality as part of the Fraunhofer FOKUS Open5GCore toolkit, as a reference for how such functionality can be prototyped, validated, and integrated with external algorithms easily, to benefit from the large body of academic research.
期刊介绍:
Annals of Telecommunications is an international journal publishing original peer-reviewed papers in the field of telecommunications. It covers all the essential branches of modern telecommunications, ranging from digital communications to communication networks and the internet, to software, protocols and services, uses and economics. This large spectrum of topics accounts for the rapid convergence through telecommunications of the underlying technologies in computers, communications, content management towards the emergence of the information and knowledge society. As a consequence, the Journal provides a medium for exchanging research results and technological achievements accomplished by the European and international scientific community from academia and industry.
