随着全球5G移动的网络的积极部署，提高运营效率和客户体验是网络运营商的一些重要目标。一种新兴的基于微服务的云原生设计为构建灵活而有弹性的网络架构提供了机会。从运营效率和可用性的角度来看，核心网络功能的过载控制是一个关键和独特的设计考虑因素，取决于端到端5G解决方案。我们研究了接入和移动性管理功能（AMF）扩展的具体案例，并介绍了如何将其用于其他5G核心网络领域。本文的目标是讨论5G核心网络中可能发生的过载情况的不同原因和类型，以及过载检测、控制和预防机制。本文还介绍了在各种服务提供商网络的实际部署经验中研究和发现的核心网络设计选项。核心网络功能的微调预计将确保过载情况下的最佳性能。
With an aggressive deployment of 5G mobile networks worldwide, improved operational efficiency and customer experience are some of the important goals of network operators. An emerging micro-services-based, cloud-native design provides an opportunity to build a flexible and elastic network architecture. From an operational efficiency and availability perspective, overload control of core network functions is a key and a unique design consideration depending upon the end-to-end 5G solution. We have studied a specific case of Access and Mobility Management Function (AMF) scaling and presented how it can be used in other 5G core network areas. The goal of this paper is to discuss different reasons and types of overload conditions that can happen within the 5G core network, as well as discuss the overload detection, control, and prevention mechanism. The paper also presents the core network design options studied and discovered during real-world deployment experience at various service provider networks. A fine-tuning of core network functions is expected to ensure optimal performance of overload scenarios.
