GPRS Core Network - Wikipedia, the free encyclopedia

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). It does this by carrying the subscriber's data from the subscriber's current Serving GPRS Support Node (SGSN) to the GGSN which is handling the subscriber's session. Three forms of GTP are used by the GPRS core network

Reference points and interfacesWithin the GPRS core network standards there are a number of interfaces and reference points (logical points of connection which probably share a common physical connection with other reference points).
