Advanced: 5G Service Based Architecture (SBA)

[@roshcoben8820]

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!

[@tusharsankpal2039]

Simply reading what is written. Teaching any concept is an art!!

[@3G4G5G]

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

[@ishratalikhan7528]

Really very very nice presentation. Keep good work.

[@WijthaGayan]

Thank you for the video 📸

[@anuradhag4717]

Best lecture for understanding 5G!

[@mayankkul87]

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!!

[@3G4G5G]

Thanks, comments like these keep us going 😊

[@suresh568]

Thank you ....nice ,it allowed me to learn new concept of 5G

[@anilmariyani9811]

Good Explanation, worth spending 20 mins on this video

[@punjabiexplorer]

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??

[@3G4G5G]

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.

[@sisirpatra5374]

It is a very goood presentation to learn the concept of 5G architecture .Many thanks ..

[@Rated_NPK]

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!

[@roberthart1093]

excellent job

[@ashishpatel2171]

It's really good video to understand 5G concepts deeply.

[@Crossyourboundaries]

Very Good and summarized

[@shahidhameed5980]

Excellent & interesting presentation

[@ksjirafe]

Nicely explained. Thanks a lot.

[@marcialenicevicentinidecar414]

Excellent! Thank very much .

[@MissInfoSec360]

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 ?

[@3G4G5G]

Hi Parveen, for security related information, please check this post and video out - blog.3g4g.co.uk/2019/04/evolution-of-security-from-4g-to-5g.html

[@Vitulli1970]

Thank you sir.

[@bushramohsin7184]

hi, I want to ask question related to RAN and Core Slicing in 5g. can you give a detail video on it

[@3G4G5G]

Hello, check the 3G4G blog. Maybe start with this post: blog.3g4g.co.uk/2020/11/network-slicing-tutorials-and-other.html

[@neeraj1174]

Thanks, Good explanation

[@gsvardhan]

Thanks for a detailed explanation:)

[@mohit64625]

Very very helpful. Thank you.

[@rajd3547]

Thanks for the explanation. Can you please cover up the all connectivity parts like n1 n2 ..and differences in detail

[@3G4G5G]

Frankly, there are many other topics we have been asked to cover and we are hoping some of the other technical KZbin channels will cover N1, N2, etc.

[@manassahoo5269]

very good

[@vikramranabhatt]

Excellent presentation !

[@rajbharat15]

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..?

[@3G4G5G]

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

[@StartInvestingwithme]

Thanks

[@vaibhavverma7556]

many thanks for this!!

[@nagendrenkrishnamoorthy195]

Thanks a lot. Nice explanation.

[@3G4G5G]

Glad you found it useful. Please help promote the channel. Thanks.

[@nagendrenkrishnamoorthy195]

I will promote this channel. Meanwhile, Do you have link to slide set?

[@3G4G5G]

See our slideshare: www.slideshare.net/3G4GLtd

[@nagendrenkrishnamoorthy195]

Thanks

[@3G4G5G]

By the way, hopefully you found the slides on our Slideshare: www.slideshare.net/3G4GLtd/

[@rosaangela8892]

Thank you. What about signaling protocolos

[@3G4G5G]

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

[@jarringjin]

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?

[@3G4G5G]

If you check out the CUPS presentation, jump to 13 minutes and you can see the interfaces. Hopefully this direct link should work: kzbin.info/www/bejne/rmbTXnemhMujaKs

[@rishim10]

Many Thanks. Is it Possible to put a Presentation on New NW Nodes being Introduced in EPC with MTC / mMTC ? Thanks

[@3G4G5G]

We will put it on our todo list. May take a long time though. There are already too many items and not enough time.

[@rishim10]

Appreciate your quick response and Information Sharing to the Community. Cant wait for your next Videos.

[@maverickmaverick5]

Have you in any of your videos covered 5G to 4G to 3G interworking for data and voice call-flows ?

[@3G4G5G]

No, sorry. No plans either.

[@kashifmahmood8120]

NSSF is used to select AMF but a UE first connects to AMF so is it the default AMF which is selected first.

[@3G4G5G]

Either the AMF based on NSSAI or if not possible from a set of default AMFs. See 23.501 5.15.5.2.1 for more details.

[@nagendrenkrishnamoorthy195]

Do you have more material for SBA? what is the benefit of having SBA?

[@3G4G5G]

Best to go through 23.501. I am sure search will return some good info on SBA as well.

[@Susheel745]

Could you please tell me the interface b/w UE & gNB ? Although it's a very basic question. Is it same as LTE interface Uu?

[@3G4G5G]

Its still referred to as Uu interface. Check out the specifications here: www.3g4g.co.uk/5G/5Gtech_0003_Standards.html

[@kashifmahmood8120]

In SBA how do you define a service. Can you give some examples

[@3G4G5G]

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."? Read more here: www.3gpp.org/NEWS-EVENTS/3GPP-NEWS/1930-SYS_ARCHITECTURE

[@abusufyan.90]

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.

[@3G4G5G]

No worries, glad to know.

[@kashifmahmood8120]

What is it there for the operators to support SBA

[@3G4G5G]

Not sure what you mean. If an operator is supporting 5G, but default their vendor would be supporting SBA to be compliant to 3GPP standards.

[@kashifmahmood8120]

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.

That's a question for the experts. We suggest you ask in LinkedIn groups. This is the best one: www.linkedin.com/groups/7489690
