Working groups

Discover the essential element
of GSMA Membership

What are working groups? 

Working towards common goals, including roaming, interconnection, billing, devices, fraud, security, and more, working groups are what make mobile work. They facilitate collaboration, consensus building and harmonisation among GSMA members, create frameworks and requirements for operational matters and influence mobile industry standardisation and solution development.

Working Group Terms of Reference

Each individual Working Group has its own terms of reference to set out the scope and remit of the group in its subject matter area. However, there are certain aspects that are common to all Working Groups and these are set out in the following generic terms of reference that apply to all groups:

  • Provide a forum for consensus building and harmonisation among members concerning the setting of frameworks and standards in respect of operational matters;
  • Liaise with and act as point of contact for external organisations in relation to matters within their remit, keeping GSMA Standards team appraised to maintain an overall picture of GSMA engagement for all external organisations;
  • Develop and maintain guidelines, recommendations and processes necessary to support efficient roaming, interconnection and interworking;
  • Provide enablers necessary for the successful development and rollout of new services;
  • Collaborate across the GSMA membership and provide expert input and contributions where necessary;
  • Develop and maintain educational materials on subject matters areas for the benefit of GSMA members;
  • Promote and monitor compliance with industry best practice and recommendations;
