Diameter S6a CLR to MME on transition to 3G registration

+2 votes
323 views

An UE is registered in roaming in LTE network in combined registration (in both MME and VLR).
When the UE returns to its home network in 3G network, does the home network generate both MAP-CANCEL (to the previous VLR) and CLR (to the previous MME)?
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?

Diameter Charging: Redirecting data session of End of Credit

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.
