LTE Protocol Stack

Over the weekend, I was looking in the standards for an LTE Protocol stack and none of the diagrams seemed simple enough so I made one myself.
I also found a very detailed one on Nomor Research site.

I was also looking for some details on EMM (EPS Mobility Management) and ECM (EPS Connection Management) and found couple of (expected ;) blogs that had the required information. If interested have a look here and here.
