3GPP 21.900 v20.0.0 — the document's own text
1 Scope
Taught in 1. Why anybody writes a standard down (How standards actually get made, in depth), 2. The shape of 3GPP, and where the data stops (How standards actually get made, overview), 2. Who writes them — two organisations, two habits (How standards actually get made, quick start).
This document outlines the working methods to be used by the 3GPP Technical Specification Groups and their Working Groups and their Sub-Groups, and by the 3GPP Support Team in relation to document management, i.e. handling of specifications, updating procedures, Change Request procedures, version control mechanisms, specifications status information etc. It complements the rules and procedures defined for 3GPP. This document does not stipulate the details of the internal working of the TSG Sub-Groups. From the Technical Specification Group point of view, a task and responsibility is given to a Working Group directly answering to the Technical Specification Group. In practice, the work/task may be carried out in a subgroup of that Working Group.
