3GPP series of Technical Specifications and Reports

The glossaries about features, network elements, reference points and identifiers are being reconstructed. This should be completed before the next plenary meetings of Dec 2019. Regarding the glossary of UICC files, the information is now concentrated in TS 31.10x specifications. Note that 30- and 50-series are no longer covered, and that the dedicated pages for those TS/TR marked "stopped" are being removed.
How initial GSM series have been split into 3GPP series
After the quarterly TSG (SA, CT, RAN) Plenary Meetings, the 3GPP produces Word documents. Afterwards the ETSI publishes the PDF versions for the releases that have been frozen (i.e. from June 2018, up to Rel‑15).
The ETSI does not publish the PDF version for studies (8xx numbers, and sometimes 7xx numbers).
Except for a few cases, a 3GPP document of a given release is a superset of the same document for the previous release. When this is relevant, the ToC (Table of Contents) shows the evolution of the document according to the releases.
The term 'sTR' has been introduced in order to identify those Technical Reports in the range 8, and sometimes the range 7. Technical Reports in this range are 3GPP internal working documents (of a given Release) for holding the interim results of feasibility studies about Technical Realization (Stage 2).
The 3GPP documents, in the context of this site, are classified as follows:
"living" TS
"living" TR, or
sTR for Rel‑16 and after
"static" TS, i.e. upgraded unchanged with at least the last frozen release
"static" TR, i.e. upgraded unchanged with at least the last frozen release, or
sTR for Rel‑8 to Rel‑15
discontinued TS/TR, or
sTR before Rel‑8
