Overview
This reference guide describes the interface between the SCG with Packet Data Network
Gateway (PDN-GW). It describes the control plane GPRS (General Packet Radio Service)
tunneling protocol messages v2 for EPS (Evolved Packet System) interfaces (GTPv2-C)
from the SCG and PGW. This guide lists all the interface messages and GPRS Tunneling
Protocol (GTP-C) information element used between the SCG and PGW.
The S2a interface is used in control signaling between the SCG and PDN-GW (Packet
Data Network Gateway) as well as for tunneling end user data payload within the
backbone network between both the nodes in EPC (Evolved Packet Core) network.
The GPRS Tunneling Protocol (GTP) transmits user data packets and signaling messages
between the SCG and PDN-GW. GTP encapsulates traffic and creates GTP tunnels,
which acts as virtual data channels for transmission of packet data between the SCG
and PDN-GW. A GTP tunnel is established between the SCG and PDN-GW through
Create Session Request procedure for a data session initiated from UE.
The SCG acts as trusted non-3GPP access network (TWAN) towards PDN-GW with
S2a (GTPv2) interface. In case the operator EPC network does not support the S2a
interface, the SCG can be statically configured to support S5 (GTPv2) interface, in which
case the SCG acts as Serving Gateway (SGW).
A GTP tunnel is identified by a pair of IP addresses and a pair of GTP Tunnel End Point
Identifiers (TEIDs), where one IP address and TEID is for the SCG (TWAN) and the other
is for the PGW. The TEID is a session identifier used by GTP protocol entities in the SCG
and in the PGW. GTP separates signaling from payload. Traffic is sorted onto a control
plane (GTP-C) for signaling and a user plane (GTP-U) for user data. GTP-C is a tunnel
control and management protocol and is used to create, modify and delete tunnels.
GTP-U is a tunneling mechanism, which provides a service for carrying user data packets.
On both planes, a GTP header encapsulates the data packet, called GTP Packet Data
Unit (GPDU), and a path implemented by UDP/IP is used as bearer of the GTP traffic.
Figure 1 shows the deployment of the SCG in operator networks with 3G and EPC.

Figure 1: Deployment of SCG with 3G and EPC
The SCG supports the following categories of GTP signaling traffic:
•Path Management Messages: The main purpose of these messages is to supervise
an UDP/IP path to ensure that connectivity failure can be detected on time. This is
managed by frequently sending GTP Echo or Echo response packets between SCG
and PGW.
•Tunnel Management Messages: These contain messages that establish, modify and
release GTP tunnels.
NOTE The SCG support for STA interface is being considered for the future release.
NOTE Refer to About this Guide on page 4 for the conventions used in this guide.
