GPRS Tunnelling Protocol is the defining IP-based protocol of the GPRS core network. Primarily it is the protocol which allows end users of a GSM or WCDMA network to move from place to place while continuing to connect to the Internet as if from one location at the Gateway GPRS support node (GGSN).
GTP-C is used within the GPRS core network for signaling between gateway GPRS support nodes (GGSN) and serving GPRS support nodes (SGSN). This allows the SGSN to activate a session on a user's behalf ( PDP context activation), to deactivate the same session, to adjust quality of service parameters, or to update a session for a subscriber who ...
GPRS opened in 2000 [21] as a packet-switched data service embedded in the channel-switched cellular radio network GSM. GPRS extends the reach of the fixed Internet by connecting mobile terminals worldwide. The CELLPAC [22] protocol developed 1991–1993 was the trigger point for starting in 1993 the specification of standard GPRS by ETSI SMG.
The Mobile Application Part is the application-layer protocol used to access the Home Location Register, Visitor Location Register, Mobile Switching Center, Equipment Identity Register, Authentication Centre, Short message service center and Serving GPRS Support Node (SGSN).

A Network (Layer) Service Access Point Identifier (NSAPI) is an identifier used in GPRS (cellular data) networks. It is used to identify a Packet Data Protocol (PDP) context (a unique data session) in the Mobile Station (MS) and in the Serving GPRS Support Node (SGSN). It is dynamically selected by the MS (however, the MS should ensure that the ...

The Radio Network Controller (RNC) is a governing element in the UMTS radio access network and is responsible for controlling the Node Bs that are connected to it. The RNC carries out radio resource management, some of the mobility management functions and is the point where encryption is done before user data is sent to and from the mobile.
