In plain words

In 3GPP TR 21.905, AEF means Additional Elementary Functions, the vocabulary term listed in clause 4. Separately, TS 23.222 and TS 29.222 use AEF for API exposing function, a distinct term. Informative Annex H of TS 23.222 discusses instantiation of this API exposing function by a PLMN management system or third party management system. TS 29.222 describes it as "the provider of the Service APIs and is also the service communication entry point of the service API to the API invokers", referring to the definition in TS 23.222.

How this page was made

The facts box comes straight from the 3GPP TDoc list and specification archive 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.
