GPRS tunneling protocol

The GPRS Tunneling Protocol ( GTP ) belongs to a group of IP -based tunnel protocols which are used in GSM , UMTS and LTE cellular networks to transport GPRS packets within the network infrastructure .

GTP can be broken down into several separate protocols:

• GTP-C for the transport of control information, e.g. B. for setting up and dismantling the tunnel
• GTP-U for transporting user data
• GTP for transporting data for billing
• GTP * for listening to and recording such data.
