Diameter Charging: Redirecting data session of End of Credit

0 votes
292 views

When the credit of a prepaid subscriber is exhausted, as specified in the 3GPP Diameter spec for Gy interface (32.229), the OCS can instruct the PGW to redirect the user traffic to a TopUp server.
It is done by the OCS by setting the value of the Final-Unit-Action AVP to the Redirect value (1) and providing the Redirect-Server AVP in the CCA (Credit Control Answer) Diameter message.
Are we talking about standard HTTP redirection?
Can this traffic redirection work in case of HTTPS user traffic?

Is it implementation dependent in the Home network? (HLR & HSS)
If only MAP-CANCEL is generated, when the MME will remove the IMSI records from its internal database?
