How we check "UE purged in MME flag" set at HSS side during purge procedure?

Question

Does Mme also sends Purge(PUR) to HSS before sending delete session request to SGW when MME receives detach request from enodeb side ?
It would be great if you give your valuable suggestion ?

Answer 1

I guess should be same as MS purged for EPS, this flag is set in the HSS per IMSI record in order to indicate that the subscriber data for the MS concerned have been purged in the MME. The parameter can take following value
- MS purged for EPS;
- MS not purged for EPS.
The default value is "MS not purged for EPS". The parameter is temporary subscriber data, stored in the HSS for a PS subscription.

IMSI record :)

Answer 2

The Purge UE Procedure shall be used between the MME and the HSS to indicate
that the subscriber"s profile has been deleted from the MME either by an MMI interaction or automatically,
e.g. because the UE has been inactive for several days.
