Within 3GPP, the technical specification development work is accomplished by Technical Specification Groups (TSGs) according to the principles and rules contained in the Project reference documentation (Partnership Project Description, Partnership Project Agreement, Partnership Project Working Procedures).
The 3GPP Technical Specification Groups (TSGs) are responsible for:
- Establishment and monitoring of the detailed 3GPP release content and time plan;
- Development, approval and maintenance of Technical Specifications and Technical Reports;
- Technical co-ordination of related Working Groups (WGs) in which Technical Specifications and Technical Reports are produced.
The TSGs periodically report to the Project Coordination Group (PCG) and may liaise with other standardization bodies, industry fora and Market Representation Partners (MRPs) as appropriate.
Technical Specification Groups (TSGs)
The TSG leadership is responsible for the allocation of resources within each group. These responsibilities include:
- Preparation of a detailed time frame and management of each Release.
- Proposal and approval of work items within the agreed scope and terms of reference of the TSG.
- Management of work items.
- Technical Co-ordination.
- Recommending, to PCG, an appropriate approach to work outside the scope of the 3GPP, but where a common global solution is desired.
- Maintenance of the TSG voting list of Individual Members.
The Technical Specification Groups in 3GPP are:
- Core Network & Terminals (CT)
- Radio Access Networks (RAN)
- Services & Systems Aspects (SA)
