3GPP Series & technologies

The first two digits of a 3GPP TS or TR number define the spec series; for example LTE radio (E-UTRAN) is defined in the 36 Series.

On this page you can find which technology is [at least partially] aligned with which 3GPP series.

A-Z list of technical terms

The 3GPP Report ‘Vocabulary for 3GPP Specifications’ identifies specialist technical terms used;

• To ensure that editors use terminology that is consistent across specifications.
• To provide a reader with convenient reference for technical terms that are used across multiple documents.

Furthermore, you can check which Spec(s) a term or abbreviation is defined in using ETSI’s TEDDI application. Note that this only shows terms defined in 3GPP TSs and TRs which have already been transposed as ETSI publications.
