Multi-access Edge Computing (MEC) and Network Slicing are two key enablers for 5G, particularly to empower low-latency services, known as Ultra-Reliable Low Latency Communications (URLLC). However, MEC and Network Slicing are evolving in parallel, and are being defined by two different standardization bodies, ETSI and 3GPP, which limits their integration and their benefits as complementary solutions. In this paper, we fill this gap by providing a novel scheme, compliant with both ETSI and 3GPP, that integrates these two key technologies and brings enhanced slicing capabilities to the edge of the 5G network. In particular, we devise a novel management and orchestration architecture, based on the latest 3GPP specifications, which integrates MEC as a 5G sub-slice. Furthermore, we highlight several issues that emerge when extending Network Slicing to the edge, security and isolation included, providing a solution for each issue.

迈向 5G 中支持切片的多路访问边缘计算


多接入边缘计算 (MEC) 和网络切片是 5G 的两个关键推动因素，特别是支持低延迟服务，即超可靠低延迟通信 (URLLC)。然而，MEC 和网络切片正在并行发展，并由两个不同的标准化机构 ETSI 和 3GPP 定义，这限制了它们的集成及其作为补充解决方案的优势。在本文中，我们通过提供一种符合 ETSI 和 3GPP 的新颖方案来填补这一空白，该方案集成了这两种关键技术，并为 5G 网络边缘带来了增强的切片功能。特别是，我们基于最新的 3GPP 规范设计了一种新颖的管理和编排架构，将 MEC 集成为 5G 子切片。此外，我们重点介绍了将网络切片扩展到边缘时出现的几个问题，包括安全性和隔离性，并为每个问题提供了解决方案。
