4.2.8.5.2 Reference Architecture

Taught in 10. Radio, Wi-Fi, cable — every way in (The 5G system architecture, in depth), 7. Roaming, other accesses, the edge and the outside (The 5G system architecture, overview).

The architecture diagram in Figure 4.2.8.5.2-1 is based on the general 5GS architecture diagrams in clause 4.2 and shows the main network functions required to support 5GC access from N5CW devices. Other network functions are not shown for simplicity.

The reference architecture in Figure 4.2.8.5.2-1 also supports N5CW device access to the subscribed SNPN or access to the SNPN with credentials owned by Credentials Holder. Other parts of the architecture are the same as defined in clause 5.30.2.9.
