International Mobile Telecommunications-2000, also known as the Third Generation Mobile Systems, will fulfill one's dream of making anywhere, anytime communications a reality, providing a framework for worldwide wireless access by linking the diverse system of terrestrial and/or satellite based networks.

For more systematic standardization activities matching the international trends, in 1999, TTA joined 3GPP and 3GPP2 while having established IMT-2000 Project Group (PG01) as the domestic corresponding entity.
