The 3rd Generation Partnership Project (3GPP) is a collaboration agreement that was established in December 1998. It is a co-operation between ETSI (Europe), ARIB/TTC (Japan), CCSA [1] (China), ATIS (North America) and TTA (South Korea).

The scope of 3GPP is to make a globally applicable third generation (3G) mobile phone system specification within the scope of the ITU's IMT-2000 project. 3GPP specifications are based on evolved GSM specifications, now generally known as the UMTS system.

Note that 3GPP should not be confused with 3GPP2, which specifies standards for another 3G technology based on IS-95 (CDMA), commonly known as CDMA2000.

[edit] Standards

3GPP standards are structured as Releases. Discussion of 3GPP thus frequently refers to the functionality in one release or another.

Version Released[1] Info
Release 98 1998 This and earlier releases specify pre-3G GSM networks
Release 99 2000 Q1 Specified the first UMTS 3G networks, incorporating a CDMA air interface[2]
Release 4 2001 Q2 Originally called the Release 2000 - added features including an all-IP Core Network[3]
Release 5 2002 Q1 Introduced IMS and HSDPA[4]
Release 6 2004 Q4 Integrated operation with Wireless LAN networks and adds HSUPA, MBMS, enhancements to IMS such as Push to Talk over Cellular (PoC), GAN[5]
Release 7 In progress (expected mid-2007) Focuses on decreasing latency, QoS and improvements to real-time applications like VoIP.[6] This specification will also focus on HSPA+ (High Speed Packet Access Evolution), SIM high-speed protocol and contactless front-end interface (Near Field Communication enabling operators to deliver contactless services like Mobile Payments), EDGE Evolution.
Release 8 and onwards In progress (expected 2009) E-UTRA, All-IP Network (SAE). Release 8 constitutes a refactoring of UMTS as an entirely IP based fourth-generation network.

Each Release incorporates hundreds of individual standards documents, each of which may have been through many revisions. Current 3GPP standards incorporate the latest revision of the GSM standards. 3GPP's plans for the future beyond Release 7 are currently in the development under the title Long Term Evolution ("LTE").

3GPP documents are made available freely on the organisation's web site. Whilst 3GPP standards can be bewildering to the newcomer, they are a remarkably complete and detailed resource and provide insight into how the cellular industry works. They cover not only the radio part ("Air Interface") and Core Network, but also billing information and speech coding down to source code level. Cryptographic aspects (authentication, confidentiality) are also freely specified in detail. 3GPP2 offer similar information about their system..

[edit] Deployment

3GPP systems are deployed across much of the established GSM market[7][8] (primarily Release 99 systems to date, however as of 2006, growing interest in HSDPA is driving adoption of Release 5 and its successors). Since 2005, 3GPP systems are seeing deployment in the same markets as 3GPP2 systems (for example, North America[9]). Industry commentators speculate constantly about the competing systems, with the outcome far from clear.
