[Audio] NSSAAF stands for Network Slice Specific and SNPN Authentication And Authorization Function.

[Audio] Before we understand NSSAAF, let us understand What is network slicing and why is it a good idea? Different use cases such as mobile broadband or MBB, the Internet of Things or IOT, and enterprise, put very different requirements on the network, but you do not want to build separate physical networks for the different services. Network slicing enables you to build multiple logical networks, ie network slices, on top of a common shared physical infrastructure. These network slices, typically one for each kind of service, are completely separated and independent to the extent that if something goes wrong in one slice it will not affect the other slices. This separation and independence also enables you to add new slices without impacting the rest of the network..

[Audio] Mobile Network Operators, can quickly create network slices that can support a specific application, or service. Network slices can span multiple network domains, including access, core, and transport, and be deployed across multiple operators. Each slice can have its own architecture, management, and security to support a specific use case. While functional components and resources may be shared across network slices, capabilities such as data speed, capacity, connectivity, quality, latency, reliability, and services can be customized in each slice to conform to a specific Service Level Agreement or SLA. From a business perspective, like the pizza analogy, The Mobile Network Operators may deliver portions of its own network directly to certain high value applications such as airports, ports, or stadiums. In other instances, a mobile virtual network operator may lease network resources from the MNO to serve specific vertical markets such as business parks or educational campuses. At the same time, neutral host operators may contract with the MNO for spectrum and RF resources for large in-building wireless applications such as hospitals or hotels..
