Abstract
This chapter provides a concise description of the 3GPP standards for the 5G System (5GS) and highlights the major enhancements over 4G. Network slicing, virtualization, and edge computing with enhanced connectivity, session, and mobility management are some key enhancements. They cater to the requirements of a diverse set of services requiring low latency, high reliability, or a massive number of connections for short, intermittent periods over the same network.
