About 3GPP Home
第三代伙伴計(jì)劃 (3GPP)合并了7個(gè)移動(dòng)通信標(biāo)準(zhǔn)化組織 (ARIB, ATIS, CCSA, ETSI, TSDSI, TTA, TTC),并為這些伙伴組織提供一個(gè)穩(wěn)定的環(huán)境用于制定報(bào)告和規(guī)范來定義3GPP技術(shù)。
該項(xiàng)目覆蓋了包括無線接入網(wǎng)、核心傳輸網(wǎng)和服務(wù)能力（包括編解碼，安全和服務(wù)質(zhì)量等）的移動(dòng)電話通信網(wǎng)絡(luò)技術(shù)，如此便提供了完全的系統(tǒng)規(guī)范標(biāo)準(zhǔn)。并且該規(guī)范也支持了非無線接入網(wǎng)的接口，并支持同WIFI網(wǎng)絡(luò)的互操作。
3GPP的標(biāo)準(zhǔn)制定和研究是由成員公司的貢獻(xiàn)推動(dòng)進(jìn)行的，并且在工作組WG和技術(shù)規(guī)范組兩個(gè)層級(jí)進(jìn)行。
3GPP的三個(gè)技術(shù)規(guī)范組 (TSG) 如下;
· Radio Access Networks (RAN),負(fù)責(zé)無線接入網(wǎng)相關(guān)
· Services & Systems Aspects (SA),負(fù)責(zé)業(yè)務(wù)和系統(tǒng)方面相關(guān)
· Core Network & Terminals (CT) 負(fù)責(zé)核心網(wǎng)和終端相關(guān)
· TSG 當(dāng)前架構(gòu)
·
工作組WG在TSG中, 定期舉行工作組會(huì)議并出席他們所屬的TSG全體會(huì)議，在會(huì)議提供或者獲取信息，討論或者批準(zhǔn)（技術(shù)標(biāo)準(zhǔn)）,。
每個(gè)TSG 都在自己特定的職責(zé)范圍進(jìn)行報(bào)告和規(guī)范的制定。
無線技術(shù)發(fā)展的里程碑：
Generations of Mobile Systems
Generation | Major Systems Milestones |
1G | Analogue technology, from the 1980s onwards.
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 Integrato), JTACS (Japan Total Access Communications System) and TZ-80n (Source:wikipedia) |
2G | First digital systems, deployed in the 1990s introducing voice, SMS and data services.
The Primary 2G technologies are: GSM/GPRS & EDGE, CDMAOne, PDC, iDEN, IS-136 or D-AMPS. |
3G | The 3G 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 for the 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 Packet data Access (HSPA). 3G brought a global vision to the evolution of mobile networks, with the creation of the ITU's family of IMT-2000 systems which included EDGE, CDMA2000 1X/EVDO and UMTS-HSPA+ radio access technologies. |
3G/4G | LTE and LTE-Advanced have crossed the “generational boundary” offering the next generation(s) of capabilities. With their capacity for high speed data, significant spectral 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 of Things (IoT) sector, Transport (Rail, ITS, etc), Education and many other areas. LTE-Advanced Pro is 3GPP's stepping stone to 5G systems. |
What comes next?
The introduction of 5G will be the result of improvements in LTE, LTE-Advanced and LTE Pro, but this will soon be followed by a major technology step, with the prospect of an entirely new air interface. The first drop of 'New Radio' features, in Release 15, will form the first Phase of 5G deployments.
Full compliance with the ITU’s IMT-2020 requirements is anticipated with the completion of 3GPP Release 16 at the end of 2019 - In Phase 2 of the 3GPP 5G effort.
For details of the contents of each Release, see the appropriate ’Release Description’ document (see link at bottom of this page).
Details of all 3GPP Work Items are in the 3GPP Work Plan, which provides details of the cooperation between all of the 3GPP groups on "Features", defined as ’new or substantially enhanced functionality which represents added value to the existing 3GPP system’.
