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.
