Usage
The PGW Restart Notification (PRN) message is sent by the S-GW when it detects a peer P-GW has
restarted. After the affected subscribers have been deactivated, the MME/S4-SGSN will prioritize the re-
activation of impacted PDN connections based on subscribed APN restoration priority, if received from the
HSS. If an APN restoration priority is not received from the HSS, then this locally configured value is used.
If there is no local configuration then by default such PDNs will be assigned the lowest restoration priority.
The MME will only restore PDNs for which the APN restoration priority is configured and/or received from
HSS. Otherwise PDNs will be released by regular deactivation.
For the MME, refer to the LTE Policy > LTE Emergency Profile >
