Network slicing has long been proposed as the mechanism enabling multiple use cases to coexist over a common physical network, with each allocated the resources and QoS it needs under distinct SLAs (service level agreements). 5G has three broad service classes, defined by overall traffic and user characteristics – uRLLC (ultra-reliable low latency communication) for minimum delay; mMTC (massive machine-type communication) for high IoT device density at low speed; and eMBB (enhanced mobile broadband) for high speed and capacity. All three of these have roots in 4G through early deployments, with a degree of customization available through features such as access point names (APNs) and Multi-Operator Core Network (MOCN). But the focus under 4G was primarily on eMBB – to…
