3GPP2

The Third Generation Partnership Project 2 (3GPP2) is the

Partnership Project for Global cdma2000® Specifications

including:

• cdma2000 air interface specifications

• Mobile Application Part (MAP) core network specifications

• Wireless IP network specifications

• All IP multimedia domain specifications

• RAN specifications

• Other ancillary specifications

3GPP2 is also reviewing 3G and beyond work such as that for IMT-

Advanced

3

More Specifically, 3GPP2 is:

• A collaborative third generation (3G) telecommunications

specifications-setting project

• Comprised of interests from the Americas and Asia developing

global specifications for MAP “Wireless Radiotelecommunication

Intersystem Operations” network evolution to 3G

• Focused on global specifications for the radio transmission

technologies (RTTs) supported by MAP and the wireless IP core

networks, together known as the cdma2000 family of standards
