Query: An Overview of 5G System Accessibility Differentiation and Control   5G system is characterized by its capability to support a wide range of use
cases and services. Supporting accessibility differentiation becomes therefore
essential to preserve a stable network condition during high traffic load,
while ensuring connection and service quality to prioritized devices and
services. In this article, we describe some use cases and requirements that
impact the 3GPP design of the 5G accessibility differentiation framework. We
then provide an overview of the supported mechanisms for accessibility
differentiation and control in 5G Stand Alone (SA) system, including cell
barring and reservation, unified access control, paging control, random access
control and admission control. We discuss how these functionalities can be used
to maintain the service quality and selectively limit the incoming traffic to
the network at high load situations, leveraging different connection-type
indicators and connection-priority identifiers.
