I never really comment or like videos, But after watching this video i felt i absolutely had to note here how brilliant this video is. I have not found anywhere that gives a better overview of these protocols and how they work together.
Please do more videos!! You're a life saver!!! I'm studying telecommunications for work and this is a great tutorial for new employees. I will pass this to my co-workers at work!! THANK YOU!!!!
Thanks for the comments everybody. It's really appreciated. I also just uploaded a few on EPS architecture if anyone's interested. I might redo this video soon also, as I felt I fumbled a bit too much on the SCCP call flow to my liking. I do all these in one take, so there's almost always a spot or two I felt could have been better. Part of the reason my video count is so light I'm sure. :)
Dear DeLong ....after watching this video ..now it becomes more easier for me to understand the signaling Part.Like SS7 and sigtran ..Could you please upload video for data call flow ..? thanks.
Hi Khaled, What specifically do you mean by "data call flow"? If you're talking about EPS registration in a mobile context, I have a video on that actually: ruclips.net/video/1h-hyQeqg2Q/видео.html If that's not what you mean, can you clarify? "Data call flow" is kind of ambiguous. :)
Dear ***** thanks for your attention...I wanted to mean ..How a mobile subscriber browse internet ? like the signaling between BSS to SGSN then to GGSN. Finally,thanks again for the EPS attach Procedure .All the video lectures you provided are informative and easy to understand.
Oh, so for setting up an Internet connection, that's basically the EPS Attach procedure (which results in a user getting an IP address in a "PDN" which can for example be the Internet). As for SGSN, GGSN and BSS, you're referring to the GPRS-equivalent of the same thing. If you look at the comparison I have near the end of the following video, I explain how SGSN, GGSN and BSC/RNC map into the newer EPS architecture: ruclips.net/video/dY2_17wmBxg/видео.html In terms of procedures, for GPRS you're talking about two call flows basically. The "GPRS Attach" procedure followed by the "PDP Context Activation" procedure. Logically it's extremely similar to the EPS Attach, done in two steps.
As it relates to this SS7 video, I should mention that while the EPS uses Diameter for subscriber authentication, in GPRS the SS7 network is used. In that setup, this video is basically the SGSN -> HLR signaling (replace MSC with SGSN in the video, and that's effectively the exchange). Further, the signaling between the RNC and SGSN there is RANAP, which is also SS7 signaling and can be routed in much the same way.
thanks for the video! great explaining. just one note,i think HLR have its GT from the E.214 range rather than the E.164. if you can see any SAI/Update location trace you will see the HLR GT falls under E.214. in some cases it can fall under E.164 but that is used to skip the steering tool if the other operator is using it (this is in a roaming scenario)
Thanks! That's true, it can use either. If it's a single PLMN you can also use straight point code translation for it, routing to the HLR application on SSN rather than GT. (TS 29.002, 6.1.3.3.2). There are a lot of areas on these videos where I was mostly giving the "most common" way to do it because I found I'd get way into the weeds if I focused too much on anything.
God really russel u helped me alot. thanks for your time on this ss7 tuto. it simplified for me . i like the way you took it from scratch and gone step by step . good job keep it up .
very nice video ,easy to understand tried to capture and explain all possible thing, i never found any video which explain when to use SCCP and TACP like u did. i am requesting please share one such informative and well explained vidoe with example to understand well only on SIGTRAN. Also if possible please make some video on VoIP, SIP.
This is gold. Everytime I watch this video, I grasp more and more info. Been watching intermittently for 8 years. Hahah.
Here I am again.

Russell,
I can't stress enough how fantastic your training is. Thank you so much for your efforts.
Please do more videos!! You're a life saver!!! I'm studying telecommunications for work and this is a great tutorial for new employees. I will pass this to my co-workers at work!! THANK YOU!!!!

Wonderful work Russell. This is a great way to spread the knowledge. I'm eagerly waiting to see all your videos. A big thank you!
great video about SS7...even good presentation .. putting all together and you explained nicely and all doubt got clear..
This is good information and many thanks for sharing this...

Hello. After a whole load of trying to learn this stuff, your video was gold. Do you have any recommendations for tutorials about MAP and CAP?
God really russel u helped me alot. thanks for your time on this ss7 tuto. it simplified for me . i like the way you took it from scratch and gone step by step . good job keep it up .
Great - Thank you Russell, very useful and well explained
Thank you Russel. The video was very informative. I learnt a lot from it.!
very nice video ,easy to understand tried to capture and explain all possible thing, i never found any video which explain when to use SCCP and TACP like u did.
i am requesting please share one such informative and well explained vidoe with example to understand well only on SIGTRAN.

Thank you for the video! Really good presentation skill! please go on with more videos on core network topics
Love this guys video. At first I thought the telephone is a house haha..
excellent presentation!!
Great video, was looking into SIGTRAN , this is the first link I clicked and it explained exactly what I wanted to know.
Thanks :)
Its good explanation about SS7 and Sigtran, its clear di differences between them, thanks for posting.
Really great work. I am new to telecom and coming from IP background. Until now it was never so clear to me. Please do more videos. Thanks
Thanks Russell for your complete explanation
Very good video. Thanks Russell for the video.
I loved it, thanks!
Thank You Russell...I know you must be busy but if you get a chance could you please make a video on DNS in EPC environment.Thanks again!!!
