3GPP

The 3^rd Generation Partnership Project (3GPP) is an international collaboration of a number of telecommunications standards bodies to standardize UMTS. The current Organizational Partners are Japanese (ARIB and TTC), Chinese (CCSA), European (ETSI), American (ATIS) and Korean (TTA).

The original scope of 3GPP was to produce standards for UMTS, or to put it more precisely 3rd Generation Mobile System based on evolved GSM core networks and the radio access technologies that they support (i.e., Universal Terrestrial Radio Access (UTRA) both Frequency Division Duplex (FDD) and Time Division Duplex (TDD) modes). The scope was later amended to include the maintenance and development of the Global System for GSM including evolved radio access technologies, such as the General Packet Radio Service (GPRS) and Enhanced Data rates for GSM Evolution (EDGE).
