GTP protocol

GTP’ (GTP prime) is an IP based protocol used within GSM and UMTS networks. It can be used with UDP or TCP . GTP’ uses the same message structure as GTP (GTP-C, GTP-U), but it is largely a separate protocol. GTP’ uses registered UDP/TCP port 3386.

GTP is the primary protocol used in a GPRS core network and allows users in a 3G or 4G network to move from one location to another while remaining connected to the Internet as if from one location at the GGSN or P-GW by carrying user traffic from the user’s current SGSN or S-GW to the GGSN or P-GW that handles the …

GPRS Tunneling Protocol (GTP) has been at the heart of providing seamless interconnection and is responsible for carrying traffic between roaming or home subscribers and key network interfaces in 4G, 5G non-standalone (NSA), 5G standalone (SA), and mobile edge compute architectures.

GTP comprises three types of traffic—control plane (GTP-C), user plane (GTP-U), and charging (GTP’ derived from GTP-C) traffic . Enabling GTP security on the Palo Alto Networks firewall allows you to statefully inspect, validate, filter, and perform security checks on GTPv2-C, GTPv1-C and GTP-U protocol messages.

GTP comprises control plane (GTP-C), user plane (GTP-U), and charging (GTP’ derived from GTP-C) traffic transferred on UDP/IP .

A GTP tunnel is a channel between two GPRS support nodes through which two hosts exchange data. The S-GW receives packets from the user equipment and encapsulates them within a GTP header before forwarding them to the P-GW through the GTP tunnel .17 Kas 2011

GPRS Tunnelling Protocol (GTP) is a group of IP-based communications protocols used to carry general packet radio service (GPRS) within GSM, UMTS, LTE and 5G NR radio networks . In 3GPP architectures, GTP and Proxy Mobile IPv6 based interfaces are specified on various interface points.
