A Report on the technical terms used
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.

In September 2009 the 3GPP Partners made a formal submission to the ITU proposing that LTE Release 10 & beyond (LTE-Advanced) be evaluated as a candidate for IMT-Advanced.

LTE (both radio and core network evolution) is now on the market. Release 8 was frozen in December 2008 and this has been the basis for the first wave of LTE equipment. LTE specifications are very stable, with the added benefit of small enhancements being introduced in Release 9, a Release that will be functionally frozen in December 2009.

High-Speed Packet Access
Parity between DSL-type broadband speeds and mobile broadband moved a step closer with HSDPA delivering up to 14Mbps in the downlink and HSUPA returning 5.8Mbps in the uplink.
Specifications for HSPA are included in Release 5 (Downlink) and Release 6 (Uplink) of 3GPP specifications.
HSPA improvements in UMTS spectrum efficiency are achieved through:

General Packet Radio Service / Enhanced Data rates for Global Evolution
GSM™ is a circuit-switched network; ideal for the delivery of voice but with limitations for sending data. The standard for GSM was designed to evolve. In 2000 the introduction of General Packet Radio Service (GPRS) added packet-switched functionality and ‘kick started’ the delivery of the Internet on mobile handsets.
GPRS (...)

Universal Mobile Telecommunications System
UMTS is an umbrella term for the third generation radio technologies developed within 3GPP.
The radio access specifications provide for Frequency Division Duplex (FDD) and Time Division Duplex (TDD) variants, and several chip rates are provided for in the TDD option, allowing UTRA technology to operate in a wide range of bands and co-exist with (...)
