[TECH BRIEF] GPRS Tunneling Protocol (GTP) Processing

[Tech Brief] Download GTP Tech Brief

OVERVIEW

GPRS Tunneling Protocol or GTP for short is a mechanism used exclusively in cellular networks to tunnel IP packets through a mobile network core. The protocol was introduced in the late 1990s when the first generation of packetized data—known as General Packet Radio Services or GPRS—was adopted. GPRS is o en referred to as 2.5G because it runs over GSM (2nd Generation or 2G mobile technology). GTP has moved on from those humble beginnings and is used in an updated form in both 4G (LTE) and emerging 5G cellular networks.

SUMMARY
