In plain words
TS 33.535 specifies "authentication and key management aspects for applications based on subscription credential(s) in 5G system as defined in TS 33.501 [2]." The AKMA service requires a new logical entity called the AKMA Anchor Function (AAnF). Deployments can collocate AAnF with AUSF or with NEF according to operators' deployment scenarios.

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.
