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.
