GSMA represents network operators. They don't coordinate standard. 3GPP makes the spec and sends it for ITU for ratification. 3GPP has 7 organizational partners: USA represented by ATIS, ETSI for EU and CCSA for China. GSMA is one of the 17 invited market representation partners who can provide advice and participate in consensus decision making but have no vote.
