CSCum17462 - PGW Support for PCSCF Recovery
Feature Changes
P-GW Support for P-CSCF Recovery
Previously, 3GPP was evaluating options to address P-CSCF failure and recovery scenarios. Most proposals at 3GPP
included the UE being disconnected from the IMS PDN when the P-CSCF the UE was registered with failed. The other
possible scenario was when the P-GW monitored the P-CSCFs and provided an update to the UE when one of the P-
CSCFs provided to the UE had failed.

possible scenario was when the P-GW monitored the P-CSCFs and provided an update to the UE when one of the P-
CSCFs provided to the UE had failed.
Previously, the user was disconnected and all P-GWs monitored all P-CSCFs. There was a customer request to avoid
this scenario by using the S-CSCF that identifies the P-CSCF that the UE is currently registered with has failed. Then, it
triggers a PCO update for the P-CSCF IP addresses provided to the UE. If there is an indication from the HSS that P-
CSCF Recovery is required, then the PCO update is requested by the MME.
