Hello,
I have noticed that there is a possible error in the Chapter 2.2 and in particular Case 7 and Case 9 (same typing error).

In other words, it is mentioned that: "the UE is in Idle State (EMM-Deregistered, ECM-Idle and RRC-Idle)", but the correct state in the parenthesis should be: EMM-Registered, ECM-Idle and RRC-Idle, i.e. not Deregistered. The fact that this is wrong is also denoted from the colour of the this particular phrase: it is green, so it should be "EMM-Registered + ECM-Idle + RRC-Idle".

The same applies for case 9. I guess that it is from "copy and paste"... Please correct it, since the document is very good and it explains, in not many details, how a UE moves from one State to the other, in plain english.

Hello Vassilis,
Thank you for noticing the typo. We've fixed it and posted the updated file.

Hello again,

I downloaded the latest version of the document, but I think that the error has not been corrected. I guess that my description was not clear enough.

For example in case 7, we have:

“(UE State: “EMM-Registered, ECM-Idle and RRC-Idle” --> “EMM-Registered, ECM-Idle and RRC-Idle”)

This is when the UE moves from TA1 to TA2 in the TAI list while in Idle (EMM-Deregistered, ECM-Idle and RRC-Idle) state.”
However, the first line contradicts the sentence in the parenthesis of the second line. My understanding is that they should be the same and the same color, i.e. EMM-Registered, ECM-Idle and RRC-Idle (green color) and not EMM-Deregistered, ECM-Idle and RRC-Idle (it should have been grey color, anyway).

Please let me know if my understanding is correct, or not.

(Same applies for case 9)
Thanks

Hello Vassilis,

Mistakenly, ppt version was updated. We fixed it and posted the updated word file.
Thank you for your kind noticing.

Hello,

Case #11 has the two MMEs (in the two cities) talk to each other, so perhaps adding a dotted line between them in the diagram would be in place? (Even if it may make the diagram look a bit less pretty :))
