GTP-C Path Management

Step |
Description |
---|---|
1 |
Once the GTP-C peer is discovered (an Initial GTP-C Create Session Request or an GTP-C Modify Bearer Request message is received), CN SMF/PGW-C starts sending GTP-C Echo Request Messages periodically to the new GTP-C Peer as per configuration. |
2 |
If GTP-C Echo response is not received, CN SMF/PGW-C retries sending GTP-C Echo Request (configured) N3 times for every configured T3 timer expiry. |
3 |
Once all retries are exhausted, CN SMF/PGW-C clears all the sessions associated to that GTP-C peer. |
