Integrity protected NAS message during attach request?

+2 votes

UE is sending Integrity protected NAS message in attach request with IMSI to MME and the context is getting failed, while when UE is sending ATTACH request without integrity protected the attach is complete.

What should be the idle behavior of UE while requesting attach with IMSI?

PS: attach request with GUTI is also integrity protected but it is getting success...

During a LTE attach, MME may send the UE a EMM Information message with Universal time and local time zone IE. This IE contains Year, month, day, hour, min, sec.
My problem is that I can not find any reference yet about what should be the value of the year. Is it calculated from 1900 or 2000 or as it is ? or there is some other reference year ?
Any reference spec with this particular information will be highly helpful.
