Diameter RA: life-cycle of Sh Activity
Just one question on the Diameter RA activities life-cyle. On receiving a User Data Request the RA creates an new Sh activity corresponding to the Sh Session. When it sends the User Data Answer, the activity should die.
But what about the Subscribe Notification? Does the Sh activity die after receiving the SNA or does the Sh activity remain until a following SNR with Subs-Re-Type set to UNSUBSCRIBE is sent ?
The second solution allows to send the PNR on the same SBB that the one which has sent the SNR, i.e., to correlate the PNR with the first SNR.
What is the implementation in the Diameter RA ?
Thanks a lot !
