What is GTP-C traffic?
GTP-C is used to signaling between the gateway GPRS support node (GGSN) and the serving GPRS support node (SGSN), while the GTP-U tunnel is used to encapsulate and route the user plane traffic across multiple signaling interfaces.
What are the transport layer protocols for GTP?
GTP consists of three separate sub-protocols, GTP-C, GTP-U and GTP’. GTP-C is used between SGSN and GGSN in 3G and between SGW and PGW in 4G to create, modify and delete sessions or PDP contexts. GTP-U is used between the RAN and the core network to carry the user-plane (U-plane) IPv4 or IPv6 data from the UE.
What is a GTP proxy?
GTP Proxy overview. It is a network platform which handles mobile data traffic for 2G/3G and for 4G. GTP-C and GTP-U messages are analysed, and application and security rules are applied. Every session creates a context, thus rules analyse whole session flow.
What is GTP correlation?
The GTP Correlation feature is a licensable, robust and intelligent addition to the GigaSMART® engine that enables mobile service providers to monitor subscriber data in GPRS Tunneling Protocol (GTP) tunnels.
Does 5G use GTP?
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.
