3GPP TSG CT WG4 - MAP/CAMEL/GTP/BCH/SS

The 3rd Generation Partnership Project (3GPP) is the primary body for developing technology specifications for cellular networks. It self-organises through its Working Groups coordinated by the Chairs of the Technical Specifications Groups (TSGs)

CT WG4 - MAP/CAMEL/GTP/BCH/SS (TSG Core Network and Terminals WG4) standardises stage 2 and stage 3 aspects within the Core Network focusing on:

• Supplementary Services.
• Basic Call Processing.
• Mobility Management within the Core Network.
• Bearer Independent Architecture.
• GPRS between network entities.
• Transcoder Free Operation.
• CAMEL.
• Generic User Profile.
• Wireless LAN - UMTS interworking and descriptions of IP Multimedia Subsystem.

CT WG4 is also responsible as a "protocol steward" for the some IP related protocols (this involves analysing, validating, extending if necessary, clarifying how they are used, specifying packages and parameter values).
