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. 

Thanks

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...?

Thanks it is very informative , and helpful for troubleshooting, can we also have such document for SRVCC,S1-handover,X2-handover,CSFB etc... that will be gr8.

content was having informative and helpful. Thanks!!

Thank you for your helpful document.

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.

amazing

Very good explanation. Do you have similar call flow for MO VoLTE call?

Very nice information about the PDN connection and it is a better option to make a good communication architecture. For more information have a visit on https://uaetechnician.ae/computer-data-recovery 

Thanks for this explanation.

I have a query.

Why Activate dedicated eps bearer context accept is not piggybacked with E-RAB setup response as E-RAB setup request and Activate Dedicated eps bearer context request is piggy backed.

Thanks

Thank you very much. A very useful guide when comparing with live traces.

I have a question: For PDN type IPv6, does SAEGW allocate a unique /64 prefix to each UE (which would mean 2^64 - 1 IP addresses not being used at all and getting wasted) or a /64 prefix is given to multiple UEs to derive /128 IP addresses?

Thanks .

How can I view document including pcap?
