  GPRS Core Network - Wikipedia, the free encyclopedia
The GPRS core network is an integrated part of the GSM core network.
GPRS Tunnelling Protocol is the defining IP protocol of the GPRS core network.
Within the GPRS core network standards there are a number of interfaces (points of connection from one system to another) and reference points (logical points of connection which probably share a common physical connection with other reference points).

 GPRS Tunnelling Protocol - Wikipedia, the free encyclopedia
GPRS Tunnelling Protocol (or GTP) is an IP based protocol used within GSM and UMTS networks.
GTP-U is used for carrying user data within the GPRS core network and between the Radio Access Network and the core network.
GTP is the primary protocol used in the GPRS core network it is the protocol which allows end users of a GSM or UMTS network to move from place to place whilst continuing to connect to the Internet as if from one location at the GGSN.

GPRS Tunneling Protocol (GTP) implemented at SGSN and GGSN is responsible for performing these tasks of encapsulation at GGSN and mapping onto appropriate radio access bearer at SGSN.
Preliminary deployment of GPRS will be for packet data services of best-effort nature, such as WWW, email, FTP etc. As more and more communication services, including real-time services, are offered over IP, it becomes critical for the GPRS network to support Quality of Service (QoS) for data transfer.
The DiffServ QoS architecture [9] is based on a model where traffic entering a network domain is classified and possibly conditioned at the boundaries of the network domain, and assigned to different behavior aggregates.

A simplistic diagram of a GPRS network is shown above.
As shown in the diagram the interface between a GGSN and an SGSN is called Gn, whereas the interface between the GGSN and an external data network is called Gi.
It is used for communicating with the Serving GPRS Support Node (SGSN) which again interfaces to the radio access network.
