inside the 3GPP Standardization Space

in order to ease the follow-up of 5G standards
We are creating a 3GPP space with the content for most of the 3GPP technical specifications, as well as for a number of technical reports (especially the most recent studies). When this is performed, at a satisfactory level, we will develop themes. For each 3GPP TS/TR, there is an essential table of contents (eToC) on the main page, and access to the content itself on additional pages. The left border in the eToC mentions whether the content is "available", "not available yet", or "not planned". As an alternative, for short documents, there is no eToC and the Content is displayed on the main page.
Relationship between the 3GPP space and the IETF space

TS 23.501 (5GS Architecture), TS 23.502 (5GS Procedures) and, to a lesser extent, TS 23.503 (5GS PCC Framework) are the core of the 5G system architecture. They are supplemented by TS 23.273 (5GS Location Services), TS 23.288 (Network Data Analytics Services in 5GS) and TS 23.316 (Wireless and Wireline Conver­gence Access Support for 5GS).
TS 23.501/502/503 at the core of 5GS standardization
In the representation above, "F:" indicates the number of Figures and "T:" the number of Tables. The number of internal links to a clause, figure, table, or external reference is indicated in the top right corner of a square or rectangle that represents the document. The value at the beginning of an arrow indicates the number of links to a clause, figure, or table in the document at the other end.
Upstream, the service requirements for the 5G System are defined in TS 22.261, and also TS 22.104 (Cyber-Physical Control Applications in Vertical Domains), TS 22.125 (Unmanned Aerial System (UAS) support in 3GPP), TS 22.263 (Video, Imaging and Audio for Professional Applications). Among many recent studies, we can note TR 22.822 (using Satellite Access in 5G) and TR 22.826 (Communication Services for Critical Medical Applications).
Other fundamental specifications in regards to architecture are TS 23.401 and TS 23.402 for the Evolved Packet System (EPS), from Release 8;  TS 23.228 for IMS, from Release 5;  and TS 23.060 for GPRS, from Release 3.
