3GPP Specifications - Official Publication

The 3GPP Technical Specifications and Technical Reports have, in themselves, no legal standing.  They only become "official" when transposed into corresponding publications of the Partner Organizations (or the national / regional standards body acting as publisher for the Partner). At this point, the specifications are referred to as UMTS within ETSI and FOMA within ARIB/TTC.

Some TRs (mainly those with numbers of the form xx.8xx) are not intended for publication, but are retained as internal working documents of 3GPP. Once a Release is frozen (see definition in TR 21.900), its specifications are published by the Partners.
