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 …

3GPP System Architecture Evolution Specification - Evolved Packet System (non RAN aspects)

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.

Therefore, 3GPP Rel-8 and onwards GTPv1-U entity should not listen to the well-known GTPv0 port 3386. If GTPv1 entity listens to the GTPv0 port, the entity shall silently discard any received GTPv0-U message. The following documents contain provisions which, through reference in this text, constitute provisions of the present document.

This Technical Specification (TS) has been produced by ETSI 3rd Generation Partnership Project (3GPP). The present document may refer to technical specifications or reports using their 3GPP identities, UMTS identities or

Oct 3, 2022 · GTP comprises control plane (GTP-C), user plane (GTP-U), and charging (GTP' derived from GTP-C) traffic transferred on UDP/IP. View the PAN-OS releases by model that support GTP and the 3GPP Technical Standards that GTPv1-C, GTPv2-C, and GTP-U support.

GPRS Tunnelling Protocol (GTP) specification for Gateway Location Register (GLR) Under change control: C4

May 1, 2022 · GTP can leverage additional security mechanisms across communication channels defined in 3GPP TS 33.401 such as IPSEC. GTP sits above the transport layer of the internet protocol suite encapsulated by User Datagram Protocol (UDP) within the IPv4 or IPv6 header [TS 09.600, TS 29.274].

GTP carries General Packet Radio Service (GPRS) within GSM, UMTS, and LTE networks through a group of IP-based communications protocols. GTP and Proxy Mobile IPv6-based interfaces are specified on various interface points within 3GPP architectures.

three protocol applications for mobility: GTP-U, GTP-C, and GTP’. GTP-U for user plane data traffic, GTP-C for control plane traffic, and GTP’ (GTP-prime) for charging applications. While all three were used in previous mobile generations including 2G GSM and 3G UMTS, only GTP-U is used in 5G as the remaining interfaces in 5G have evolved ...
