Widely diverse end to end services will require the ability to create a Transport Slice with guaranteed SLAs.

Ultra Reliable Machine to Machine communication will require dependable low latency communication.

Internet of things devices will require a massive increase in network connectivity.

Explosive traffic growth will require statically defined manually configured end to end QoS based services.

To improve authentication between the User Equipment and the 5G Core.

To improve authentication when connecting to different network slices.

To authenticate the User Equipment coming from an untrusted non-3GPP access (N3IWF).

This network function stores or retrieves subscriptions, profiles and authentication data to or from the data repositories. It offers services to the AMF, SMF, NEF and AUSF using the Service Based Interface.

This network function supports authentication for 3GPP and non-3GPP accesses.

This network function is part of data repositories in the Common Data Layer and in opposition to the UDR, it stores non-standardized unstructured data.

This network function provides registration and discovery functionality to enable other network functions/services to discover and communicate with each other.
