Individual release feature documents are available here.
You may also refer 3GPP Features and Study Items page to check features under various releases.
For more detailed list of specifications under a release, go to 3GPP Portal and click on Releases tab.
Specification series
Specification numbering page gives top level view of various specification series.
Specification
3gpp specifications are marked either TR or TS.
TR are "Study" documentations whereas TS are "Specifications".
TR documents are very useful to understand "why?".
TS documents cover details related to architecture, procedures, interfaces, and so on.
To download specification, you may use 3GPP FTP site or below form (e.g. type 36.300 and click on 'locate'). |
