In plain words
TS 23.288 "defines the Stage 2 architecture enhancements for 5G System (5GS) to support network data analytics services in 5G Core network." The NWDAF (Network Data Analytics Function) is part of the TS 23.501 architecture and uses its 5GC mechanisms and interfaces, plus OAM services. V20.2.0 CR subjects cover redundant transmission experience analytics, Analytics Context Transfer model information, and Signalling Storm Analytics. They also cover the time interval supporting VFL and an optimized AF method to obtain the external UE IP address in a NAT-enabled system.

How this page was made
The facts box and the tables come straight from the 3GPP specification archive and CR database as indexed by 3GPP Scout. An AI model (GPT-6 Luna) wrote the paragraph and named the source of each sentence. Code checked every quote word for word against the stored source text and every number against the cited source. A second AI model from another company (Claude Opus 5.5) reviewed the paragraph against the same sources. The 3GPP documents themselves govern.
