`About 3GPP Home
`The 3rd Generation Partnership Project (3GPP) unites [Seven] telecommunications
`standard development organizations (ARIB, ATIS, CCSA, ETSI, TSDSI, 'I'I'A, ‘I'I'C), known
`as “Organizational Partners" and provides their members with a stable environment to
`produce the Reports and Specifications that define SGPP technologies.
`
`The project covers cellular telecommunications network technologies, including radio
`access, the core transport network, and service capabilities - including work on codecs,
`security, quality ofservice - and thus provides complete system specifications. The
`specifications also provide hooks for non-radio access to the core network, and for
`intenivorking with Wi-Fi networks.

`
`The Working Groups, within the TSGs, meet regularly and come together for their quarterly TSG Plenary meeting, where their
`work is presented for information, discussion and approval.
`
`Each TSG has a particular area of responsibility forthe Reports and Specifications within its own Terms of Reference (Details
`available in the Specification Groups pages).
`
`The last meeting ofthe cycle of Plenary meetings is TSG SA, which also has responsibility forthe overall coordination ofwork

`
`The 3GPP technologies from these groups are constantly evolving through Generations of commercial cellular / mobile
`systems (see table below). Since the completion of the first LTE and the Evolved Packet Core specifications, 3GPP has
`become the focal point for mobile systems beyond BG.
`
`Although these Generations have become an adequate descriptor for the type of network under discussion, real progress on
`3GPP standards is measured by the milestones achieved in particular Releases. New features are ’functionality frozen’ and
`are ready for implementation when a Release is completed. 3GPP works on a number of Releases in parallel, starting future
`work well in advance cfthe completion ofthe current Release. Although this adds some complexity to the work ofthe groups,
`such a way of working ensures that progress is continuous & stable.

`About 3GPP Home
`
`The major focus for all 3GPP Releases is to make the system backwards and fonNards compatible where possible, to ensure
`that the operation of user equipment is un-interrupted. A good current example ofthis principle has been the priority placed in
`the working groups on backward compatibility between LTE and LTE-Advanced, so thatan LTE-A terminal can work in an LTE
`cell and an LTE terminal works in the LTE-A cell.

`
`A|| ofthese advances have provided a high degree ofcontinuity in the evolving systems, allowing existing equipment to be
`prepared for future features and functionality - delivering higher data rates, quality ofservice and cost efficiencies.
`
`Each progressive 3GPP radio access technology aims to reduce complexity and avoid fragmentation oftechnologies on offer.
`
`Core Network Evolution
`
`GSM networks used circuit—switch telephony initially, with packet—switching added with GPRS. In the UMTS architecture, this
`dual-domain concept was kepton the core network side. Some network elements were evolved, but the concept remained
`very similar.
`
`When considering the evolution ofthe 3G system towards LTE, the 3GPP community decided to use IP (Internet Protocol) as
`the key protocol to transport all services. It was therefore agreed that the Evolved Packet Core (EPC) would not have a circuit-
`switched domain butthat the EPC should be an evolution ofthe packet-switched architecture used in GPRS/UMTS.
`
`This decision had consequences on the architecture itself butalso on the way that the services were provided. Traditional use
`ofcircuits to carry voice and short messages needed to be replaced by lP-based solutions in the long term... Read more on

`
`1G
`
`Analogue technology, from the 19805 onwards.
`
`26
`
`3G
`
`Various technologies were deployed, Nationally or Regionally, including:
`NMT (Nordic Mobile Telephone), AMPS (Advanced Mobile Phone System), TACS (Total Access
`Communications System), A-Netz to E-Netz, Radiocom 2000, RTMI (Radio Telefono Mobile lntegrato),
`JTACS (Japan Total Access Communications System) and TZ-80n (Source:wikipedia)
`
`First digital systems, deployed in the 19905 introducing voice, SMS and data services.
`The Primary 2G technologies are: GSM/GPRS & EDGE, CDMAOne, PDC, iDEN, lS-136 or D-AMPS.
`
`The 36 system from 3GPP is based on evolved Global System for Mobile communication (GSM) core
`networks and the radio access technologies that they support.
`
`This has allowed forthe maintenance and development of GSM, with the evolution of General Packet Radio
`Service (GPRS) and Enhanced Data rates for GSM Evolution (EDGE), as well as further developments with
`the Universal Mobile Telecommunications System (UMTS) and High Speed Packetdata Access (HSPA).
`
`3G brought a global vision to the evolution of mobile networks, with the creation ofthe ITU's family of NT-
`2000 systems which included EDGE, CDMAZOOO 1XIEVDO and UMTS-HSPA+ radio access technologies.
`
`sG/4G
`
`LTE and LTE-Advanced have crossed the “generational boundary“ offering the next generation(s) of
`capabilities. With their capacity for high speed data, significantspectral efficiencies and adoption of
`advanced radio techniques, their emergence has been the basis for all new mobile systems from Release 8
`onwards.
`
`It should be noted that LTE-Advanced (From Release 10) is 3GPP's ITU-R IMT-Advanced radio interface.
`LTE-Advanced is the first true 4G technology to be specified by 3GPP.
`
`LTE-Advanced Pro is the name that helps the industry describe what has been achieved with the
`completion of Release 13. LTE Pro is set to be used by other sectors, beyond telecoms, including Critical
`Communications (blue light services & other Mission Critical systems), the machine-to-machine or Internet
`ofThings (loT) sector, Transport (Rail, ITS, etc), Education and many other areas. LTE-Advanced Pro is
`3GPP's stepping stone to SG systems.
`
`What comes next?
`
`The introduction of 5G will be the resultofimprovements in LTE, LTE-Advanced and LTE Pro, but this will soon be followed by
`a major technology step, with the prospect ofan entirely new air interface. The first drop of'New Radio‘ features, in Release
`15, will form the first Phase ofSG deployments.
`
`Full compliance with the ITU's IMT-2020 requirements is anticipated with the completion of 3GPP Release 16 atthe end of
`2019 - In Phase 2 ofthe SGPP SG effort.

`page).

`
`Details ofall SGPP Work Items are in the SGPP Work Plan, which provides details ofthe cooperation between all ofthe BGPP
`groups on "Features", defined as 'new or substantially enhanced functionality which represents added value to the existing
`SGPP system'.
`
`3GPP Scope
`
`The original scope ofSGPP (1998) was to produce Technical Specifications and Technical Reports fora 3G Mobile System
`based on evolved GSM core networks and the radio access technologies thatthey support (i.e., Universal Terrestrial Radio
`Access (UTRA) both Frequency Division Duplex (FDD) and Time Division Duplex (TDD) modes).
`
`The scope was subsequently amended to include the maintenance and development ofthe Global System for Mobile
`communication (GSM) Technical Specifications and Technical Reports including evolved radio access technologies (e.g.
`General Packet Radio Service (GPRS) and Enhanced Data rates for GSM Evolution (EDGE)).
`
`SGPP was created in December 1998 by the signing ofthe "The 3rd Generation Partnership Project Agreement". The latest
`3GPP Scope and Objectives document has evolved from this original Agreement.
`
`The discussions that led to the signing ofthe 3GPP Agreementwere recorded in a series ofslides called the "Partnership
`Project Description" thatdescribes the basic principles and ideas on which the project is based. The Partnership Project
`Description has not been maintained since its first creation but the principles ofoperation ofthe project still remain valid.
