3GPP 24.501 v20.0.0 — the document's own text
3.2 Abbreviations
Taught in 4. TS 24.501 — two protocols living in one document (CT1 — the group that writes what your phone says, in depth), 14. What this record cannot tell you (CT1 — the group that writes what your phone says, in depth), 4. Inside TS 24.501, the document at the centre (CT1 — the group that writes what your phone says, overview), 4. How to look at CT1's work yourself, and what the record does not say (CT1 — the group that writes what your phone says, quick start).
For the purposes of the present document, the abbreviations given in 3GPP TR 21.905 [1] and the following apply. An abbreviation defined in the present document takes precedence over the definition of the same abbreviation, if any, in 3GPP TR 21.905 [1].
