Sx Path Failure Detection

Sx path failure is detected in the following conditions:

  • Heartbeat Failure: When the peer doesn’t respond to the heartbeat sent and also to the retries.

  • Recovery Timestamp Change in Heartbeat: When the Heartbeat Response has a new Recovery Timestamp value then the previously received value. If the Recovery Timestamp value received is lower than the previously received value, the path failure isn’t detected.

  • Sx Association Message: When the Sx Association message is received again from the peer. In this case, all the calls are cleared and a notification is sent to eGTP peer.

  • Sx Association Release Message: When the Sx Association release message is received. In this case, all the calls are cleared and a notification is sent to eGTP peer.
