About 3GPP Home
第三代伙伴计划 (3GPP)合并了7个移动通信标准化组织 (ARIB, ATIS, CCSA, ETSI, TSDSI, TTA, TTC),并为这些伙伴组织提供一个稳定的环境用于制定报告和规范来定义3GPP技术。
该项目覆盖了包括无线接入网、核心传输网和服务能力（包括编解码，安全和服务质量等）的移动电话通信网络技术，如此便提供了完全的系统规范标准。并且该规范也支持了非无线接入网的接口，并支持同WIFI网络的互操作。
3GPP的标准制定和研究是由成员公司的贡献推动进行的，并且在工作组WG和技术规范组两个层级进行。
3GPP的三个技术规范组 (TSG) 如下;
· Radio Access Networks (RAN),负责无线接入网相关
· Services & Systems Aspects (SA),负责业务和系统方面相关
· Core Network & Terminals (CT) 负责核心网和终端相关
· TSG 当前架构
·
工作组WG在TSG中, 定期举行工作组会议并出席他们所属的TSG全体会议，在会议提供或者获取信息，讨论或者批准（技术标准）,。
每个TSG 都在自己特定的职责范围进行报告和规范的制定。
无线技术发展的里程碑：
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’.
