The ongoing quest for the tight integration of network operation and the network service provisioning initiated with the introduction of 5G often clashes with the capacity of current network architectures to provide means for such integration. Owing to the traditional design of mobile networks, which barely required a tight interaction, network elements offer capabilities for their continuous optimization just within their domain (eg, access, or core), allowing for a “silo-style” automation that falls short when aiming at closed-loop automation that embraces all the actors involved in the network, from network functions up to the service-provider network functions. To this end, in this article, we make the case for the network-wide capability exposure framework for closed-loop automation by (i) defining the different entities that shall expose capabilities, and (ii) discussing why the state of the art solutions are not enough to support this vision. Our proposed architecture, which relies on registration and discovery, and exposure functions, allows for enhanced use cases that are currently not possible with state of the art solution. We prove the feasibility of our solution by implementing it in a real-world testbed, employing Artificial Intelligence algorithms to close the loop for the management of the radio access network.

面向闭环网络自动化的统一的基于服务的能力开放框架

随着 5G 的引入，对网络运营和网络服务提供的紧密集成的持续追求往往与当前网络架构为这种集成提供手段的能力发生冲突。由于移动网络的传统设计几乎不需要紧密交互，网络元素仅在其域（例如，接入或核心）内提供持续优化的能力，允许“孤岛式”自动化旨在实现包含网络中所有参与者的闭环自动化，从网络功能到服务提供商网络功能。为此，在本文中，我们通过（i）定义应公开能力的不同实体，以及（ii）讨论为什么最先进的解决方案不足以支持这一愿景，为闭环自动化的网络范围能力公开框架提供了理由。我们提出的架构依赖于注册和发现以及公开功能，允许使用最先进的解决方案目前无法实现的增强用例。我们通过在真实世界的测试平台中实施我们的解决方案来证明其可行性，并采用人工智能算法来闭环以管理无线电接入网络。允许使用最先进的解决方案目前无法实现的增强用例。我们通过在真实世界的测试平台中实施我们的解决方案来证明其可行性，并采用人工智能算法来闭环以管理无线电接入网络。允许使用最先进的解决方案目前无法实现的增强用例。我们通过在真实世界的测试平台中实施我们的解决方案来证明其可行性，并采用人工智能算法来闭环以管理无线电接入网络。
