Hey this content is awesome, it summarizes and simplifies a lot of different concepts like control/user plane separation, 4G/5G contrast, Service Based Architecture the logical rep of 5G and also the network slicing concept. Great material and nice selection of diagrams and images, thank you!
You want to really learn about 5G core, don't look at the videos, start with the specifications. We have a collection here: www.3g4g.co.uk/5G/5Gtech_0003_Standards.html
Trust me this is the ever best presentation on 5GS.. very precise, descriptive, informative and helpful for any novice to 5G or even expert in this new technology.. thanks a lot for sharing such stuff. Like from my side and subscribed your channel for more updates and KS sessions. Thanks again!!
A very nice presentation that is easy to follow. Thanks for the references to specific sections of 3GPP TS for detailed study as well. Subscribed to your channel!
I donot understand why is there a need to define Reference Point interfaces and architecture for 5G core. e.g. 3GPP has defined N11 as reference point interface between AMF and SMF. But AMF and SMF will communicate to each other via RESTful API calls defined as part of service based interface. So what does N11 exactly mean??
The reference point architecture is to help people who have been used to this approach in previous generations to easily understand SBA. It also simplifies by ensuring people understand which messages can be exchanged between which NFs.
About the security between Core Networks and Access networks(5GC -- RAN), (1) How a secure session is created? What do security needs - integrity & authentication only? (2) Does it use IPsec or DTLS? (3) Does the security session has a time latency limit? (4) What is the capacity of the devices used to create the secure session ?
Good presentation ... slicing means here differnt type of data connectivity to the external world ? voice over 5g can be using current ims or any changes ? (guess too early question) AMF = MME ? also has a direct connection to PCRF..?
Slicing means creating different logical flows for a single physical flow Vo5G/VoNR can use current IMS but will be an AF AMF = MME-C (see CUPS) + some new functionality
Nice explanation for newbies. I have a question about interworking with EPC, what is the interface between EPC and 5GS for example between SMF and PGW?
If you check out the CUPS presentation, jump to 13 minutes and you can see the interfaces. Hopefully this direct link should work: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-x5p-DpOfp2I.html
Hello, not sure what you mean about signaling protocols. Are you looking for specs? If yes, check this out: www.3g4g.co.uk/5G/5Gtech_0003_Standards.html
How's this: "Compared to previous generations the 3GPP 5G system architecture is service based. That means wherever suitable the architecture elements are defined as network functions that offer their services via interfaces of a common framework to any network functions that are permitted to make use of these provided services."?

sorry don't agree with most poeple here, it seems to be just a read-out of the slides rather than explaining each point/concept. There was no need for a video though, simple offline reading too would have had the same effect.
To me the real SBA is when we move away from NF based paradigm to network service based paradigm. Ofcourse that service would be realized by 1 or many NFs. So just having SBI where all the NFs talk together directly is not SBA but a step towards SBA. So my Q was why would operators move to a network service based paradigm instead of NF bases paradigm.
