“What is 3GPP ? ”
 3GPP Stands for 3rd Generation Partnership Project (3GPP)
 The 3GPP is a collaboration between groups of telecommunications
associations, known as the Organizational Partners.
 Contribution driven companies participate in 3GPP through their membership
of one of these “Organizational Partners”.
 Currently more than 350 Individual Members (Operators, Vendors,
Regulators) 14 Market Representation Partners (giving perspectives on market
needs and drivers).
 The Partners are Standards Developing Organizations like
 ARIB & TTC - Japan, ETSI - Europe
 ATIS - USA, TTA - Korea
 CCSA - China, TSDSI – India

“The Way of Working”
 3GPP is not constrained to 3rd Generation. It includes work on both 2nd and 4th generation
technologies.
 New work initiated by member companies via Work Items outlining scope and time plan.
 Work Items prioritised if all estimated work cannot be done by the scheduled release
deadline.
 All 3GPP member companies contributes on equal terms on any work item.
 3GPP seeks consensus on all technical matters (but has mechanisms if consensus cannot
be reached).
 Release deadline respected, unfinished work deferred to a later release
 3GPP Membership is now at an all-time high, with 387 Individual members. In addition, there are
17 companies having Guest Status, which are potential IMs of the future.
