It is very good to see you sharing some of your amazing tech documents again! It is what brought me to your site in the first place. Maybe next one should be some EN-DC NSA option 3.x signalling flows? It seems this is where the industry is converging including telcos in Korea.

Very informative ...highly useful for system debugging. Thanks for sharing.
Did you observe - this is one such log where - no ESM flag activation was indicated by UE in the PDN connectivity req ... also network didn't query for identity req; it trusted the UE(/UICC) & proceeded with AIR...?

Fantastic call flow explanation.  It would be great if Netmania could provide the actual pcap file so we could examine the pcap more closely using Wireshark.  Thanks.
