In plain words
EMMI means Electrical Man Machine Interface, as defined in 3GPP TR 21.905. In TS 44.014, EMMI is a "half duplex communication link between the SS and the MS" for automatically registering the MS status, indications and performance. TS 34.109 and TS 38.509 also use EMMI, in clauses 7 and 8 respectively.

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.
