Landslide: HSS Node - Why Real MME can suddenly send a Purge Request Message after receiving the Update Location Response?
Environment/Versions
Landslide
HSS Node
EUTRAN Authentication
APN-OI-Replacement has been set with a numerical value (Ex.:123456789)
Answer
APN-OI-Replacement when present will be a part of the APN-FQDN requested to the internal DNS, this AVP is contained in the Update Location Response message.
If this value is incorrectly sent by HSS, MME could not build properly the APN-FQDN and so there is no DNS query message sent in order to obtain the PGW address.
As MME does not know where to send the creation/modification/update bearer message, the node has to purge the session (UE).
Remember, APN-OI-Replacement should have a format type like mncXXX.mccYYY.gprs.
