CSCui42572 - Error response handling at SGW
Feature Changes
Improved Error Response Handling at the S-GW
The software has been enhanced to improve error response handling at the S-GW when an erroneous message is
received by EGTPC from a peer. On receiving a bad response from the peer, instead of dropping the message while
doing validation, EGTPC informs the S-GW about the bad response received. The S-GW uses this notification from
EGTPC that a bad response is received to send a proper response to the other peer. This will reduce load on the S-GW
due to retransmissions. This also helps in capturing statistics based on the correct cause code.
