Global Standards Collaboration


The goal of the Global Standards Collaboration (GSC) is to enhance co-operation between Participating Standards Organizations (PSOs) from different regions of the world in order to facilitate exchange of information on standards development, build synergies and reduce duplication.

GSC started-out in 1990 under the name of 'Inter-regional Telecommunications Standards conference (ITSC)' an initiative of the T1 Committee of the United States who invited the other founding partner organizations ITU-T, ETSI (Europe) and TTC (Japan) to the first meeting in Fredericksburg. The ITSC, as a conference, became too big and was therefore reduced to GSC, the Global Standards Collaboration, with delegations of reasonable size (10 maximum). But the scope was basically kept the same. In 2013, the GSC's organization, including structure, scope/mandate and working methods, was reformed to better focus on strategic technical topics

GSC provides for the regular exchange of work programmes and facilitates collaboration regarding communications standards and the related development environment. In addition to the PSOs, the GSC attracts a growing number of other standardization actors from around the world who can participate as guests. As its name implies, its ultimate goal is to promote global standards collaboration in these areas of common interest.


The present membership is represented by the following organizations:

  • ARIB - Association of Radio Industries and Business - Japan
  • ATIS - Alliance for Telecommunications Industry - USA
  • CCSA - China Communications Standards Association - China
  • ETSI - European Telecommunications Standards Institute - Europe
  • IEEE-SA - IEEE Standards Association
  • ITU - International Telecommunication Union - International
  • TTC - Telecommunication Technology Committee - Japan
  • TIA - Telecommunications Industry Association - USA
  • TSDSI - Telecommunications Standards Development Society, India
  • TTA - Telecommunication Technology Association - Korea


GSC meets approximately once a year.

The last GSC-18 meeting was hosted by ETSI in Sophia Antipolis, France from 22 to 23 July 2014.
The GSC-19 meeting will be hosted by ITU in Geneva, Switzerland, from 15 to 16 July 2015.
