Third Generation Mobile System - The generic term for the next generation of mobile wireless communications networks.
Third Generation Partnership Project - A body comprising several organizational partners working to produce technical specifications for a third-generation mobile system based on GSM core networks and the radio access technologies they support known as
The 3rd Generation Partnership Project 2 (3GPP2) is a collaboration agreement that was established in December 1998. A cooperation between ARIB/TTC (Japan), CCSA (China), Telecommunications Industry Association (TIA) (North America) and Telecommunications Technology Association (TTA)(South Korea) to make a globally applicable third generation (3G) mobile phone system specification within the scope of the ITU's IMT-2000 project. In practice, 3GPP2 is the standardization group for CDMA2000, the set of 3G standards based on earlier 2G CDMA technology.
The Third Generation Partnership Project (3GPP) has adopted the ITU-T Recommendation H.324 Annex C, also referred to as H.324/M (Mobile) or H.324M (with very few changes), on their 3G-324M as the standard for multimedia telephony over 3G circuit switched cellular networks. This standard is used for handling real-time video telephony in 3G mobile handsets.
