what is meant by MMI interaction and what role does it play at purge request message at HSS

Question

at purge UE request message UE purged in MME flag is set due to MMI interaction,what does MMI interaction mean?

Comments

Purge UE: to indicate that the subscriber’s profile has been deleted from the MME or SGSN either by an MMI interaction or automatically

Here MMI indicates Man-Machine-Interface.

Not sure if I understood the question correctly.

Answer 1

I agree with Salil, MMI is nothing but manual intervention by which a person/administrator/operator can delete a user profile.
As soon as UE profile gets deleted from the system or MME database, MME initiates purge ue procedure.
