Introduction to IMS 

Clear and to the point. Gets no tired listening to you

This is the best video lectures on LTE that I ever came across. A dumb can understand what LTE is after viewing this lecture... It helped me alot in my thesis.

Amazing! 8 minutes to understand IMS, even VoLTE. Thanks for great presentation.

awesome explanation, absolute clear, many thanks for making efforts

Hey Chris, I took few of the training from your org. you the best spreading LTE :) keep it up!

It is very good information for me to put all the puzzle together for IMS network, Thank a bunch

Thanks Chris ! Greatly explained. Yann.

thank you for the explanation ,it made things clear to me

Great intro to the technology. Thanks

Very eye opening.. Thanks Chris

Thanks for the information, it is very useful !

Great!! nice way of introducing IMS.

Good one. Thank you. It would be interesting to see the whole call flow from a mobile to mobile through IMS. Also, the other services that IMS provides too.

Chris, what would be the call flow of a VoLTE call to a different operator 3G system ?

thanks Chris.. would love if you could also cover SRVCC, CSFB

its really good intro. please do likr this for all core network elements

i really have this question, i wanna know where they put the HLR or HSS "server"? like what do they call that place(center, tower, hq)

Really nice video, the explanation was concise and very illustrative, five stars for you!

In your video, SIP protocol is used for communication between drawed network entities but HSS communicates with diameter protocol only.

Hey, I came across this video from "related videos". Nice to know we're doing something similar :)

Very well explained... can you please explain Volte architecture as well.

Thanks its very informative!

thanks a lot for this useful video. I need to know what is exactly happen inside the HSS and what is the exact form of its entries. would you please help me?

it was great video , i would like to see call flow of voice call using IMS and CSFB both.

Great content. Thanks.

Very intersting, Please keep on doing that

thanks for this good video. thankyou verymuch.

Hi mwolleben,I need some info What about the feature as IMS Engineer Fresher.

Hi, pls share the more details about call flows, node to node and whats the path for signaling and bearer in IMS.

great presentation

Hello, I would like to see a video on Reference Signals and how they work in the LTE OFDMA

Please provide details of role played by AS

Can you make a video on Location Update of 3G and 4G?

Thnaks a lot. I am a trainer for similar technologies. Award Solutions is like Intel or Microsoft of Training Industry :)

excellent deck.. thanks for sharing

Thanks bidu...

Gracias es lo que necesitaba saber

look up event helix on google, they have a section on LTE and related call flows. It has it all!!

This is good one.

Really nice introduction to IMS. However, I wouldn´t say that ASs are part of IMS (in fact the 3GPP has only standardized the interfaces -ISC-). Besides, I would have included the MRF.

thanks.

Is MGCF directly connect to PSTN ?

Thanks good presentation

thanx for sharing, it really is useful

Good ...Useful

the IMS stands as a bridge between packet network and a circuit switch network providing some services. But at the end you are saying that the IMS network itself is connected (within the IMS network) by IP? Did I get that right?

Thanks for the good presentation , I want to know about the each component of IMS like CSCF , HSS , MGCF etc , and how the call is established end to end in IMS . If you have presentation for the above , please send it to me it will be very helpfull for me. thank you

Thank you ! It was very definite and clear video . Can you post a video for eHRPD ?

Awesome.. Clear and Crisp!

thks for video

what is PSTN?

Very good video,It explains basic knowledge about IMS, Thanks for sharing. Call flow diagram will more value.

is he eating all the time ? :)

Great jobs but please next time without chewing gum!

Good info but wtf is up with the gum chewing ahhhhh

Nice video

SIP details and introduction video

Do you want to eat? I have soup

This guy is very unprofessional.

Thanks its very informative!
