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. Ruckus Wireless™ SmartCell Gateway™ 200 S2a Interface Reference Guide for SmartZone 3.5.1 9 Data Session and Path Management Messages Overview 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. 10 Ruckus Wireless™ SmartCell Gateway™ 200 S2a Interface Reference Guide for SmartZone 3.5.1 Data Session and Path Management Messages Data Session Establishment Data Session Establishment Figure 2: Data session establishment on page 11 depicts session establishment based on the session such as create, modify, update and so on.
