from http://www.3gpp2.org/Public_html/S/TSGS_Scope.cfm
The Services and Systems Aspects TSG (TSG-S) is responsible for the development of service capability requirements for systems based on 3GPP2 specifications. It is also responsible for high level architectural issues, as required, to coordinate service development across the various TSGs. In this role, the Services and Systems TSG shall track the activities within the various TSGs, as required, to meet the above service requirements.
Specifically, it has a responsibility for:
More specifically, TSG-S will address the following areas of work:
通过以上这段话,我们可以得知TSG-S的工作任务是规划网络的发展,为网络发展提供总体指导。
TSG-X (Core Networks)
3GPP2(第三代合作伙伴计划2): 该组织是于1999年1月成立,由北美TIA、日本的ARIB、日本的TTC、韩国的TTA四个标准化组织发起,主要是制订以ANSI-41核心网为基础,CDMA2000 为无线接口的第三代技术规范。
3GPP2 声称其致力于使ITU的 IMT-2000计划中的(3G )移动电话系统规范在全球的发展,实际上它是从2G的CDMA One 或者IS-95发展而来的CDMA2000标准体系的标准化机构,它受到拥有多项CDMA关键技术专利的高通公司的较多支持。
3GPP(3G Partnership Project): 该组织是在1998年12月成立的,由欧洲的ETSI、日本的ARIB、日本的TTC、韩国的TTA和美国的T1五个标准化组织发起,主要是制订以GSM 核心网为基础,UTRA(FDD为W-CDMA 技术,TDD为TD-CDMA技术)为无线接口的第三代技术规范。
