Network slicing offers numerous benefits, particularly the ability to deliver highly customizable services to new industry sectors that have been unserved or inadequately served by current mobile network operators. Among new industry use cases that are targeted by the fifth generation (5G) mobile systems, there exist scenarios that go beyond what the current device-centric mobility approaches can support. The mobility of low latency communication services, shared by a group of moving devices, e.g., autonomous vehicles that share sensor data, is a prime example of these cases. These use cases' demands for ultra-low latency can be addressed by leveraging the Multi-Access Edge Computing (MEC) concept, techniques for live migration of virtual resources, Software Defined Networking (SDN), and network slicing. In this article, we define different slice mobility patterns, different methods for grouping users, and different triggers for network slice mobility. Furthermore, we evaluate the mobility of services and network slices based on the simultaneous migrations of multiple containers.

下一代移动系统中的网络切片移动性：挑战和潜在解决方案

网络切片可带来许多好处，特别是能够为当前移动网络运营商未提供或服务不足的新行业提供高度可定制的服务。在第五代（5G）移动系统针对的新行业用例中，存在超出当前以设备为中心的移动性方法所能支持的方案。由一组移动设备（例如共享传感器数据的自动驾驶车辆）共享的低延迟通信服务的移动性就是这些情况的主要示例。这些用例对超低延迟的需求可以通过利用多访问边缘计算（MEC）概念，虚拟资源的实时迁移技术，软件定义网络（SDN）和网络切片来解决。在这篇文章中，我们定义了不同的分片移动性模式，用于分组用户的不同方法以及不同的网络分片移动性触发器。此外，我们基于多个容器的同时迁移来评估服务和网络切片的移动性。
