I have described VoLTE IMS Architecture in simplified way . Are you also finding 3GPP Specs complicated & Complex for VoLTE IMS .
It covers Role played by individual Networks Elements as mentioned below :-
VoLTE SIP Handset : SIP Support , UAC , UAS , User Agent , SIP-UA
Underlying LTE Network : MME , SGW , PGW , PCRF , HSS , Dedicated Bearer , QCI , Default Bearer
IMS Core : SIP Servers , P-CSCF , I-CSCF , S-CSCF , TAS , MMTEL , BGw , MRF , ATCF , ATGW , IBCF , MGCF , IM-MGW , TrGW
Voice Core or PSTN Network for Break-in or Break-out Calls

Very helpfull.. Thank you :)
Excellent Presentation
Excellent briefing.
Great efforts. thanks.
you are awesome. well explained.
Thank you for this please back to this channel
Excellent Slides....
Well elaborated Vikas sir
thsnks for your help!!!
Excellent presentation ji👍
Really good overview. Thorough, still easy to follow/understand - and this goes to your other videos as well. I have been dealing with VoLTE for a few years now, and it would have been good to have such a good summary back in the days :) Beside engineering, are you also in education/consulting business ?
Thank you.
Quite easily explained indeed
Thanks, man!
Too good information
Nice work.
Appreciate the effort with slides...but again Teaching is one thing and reading lines from PPT is another...
Excellent
thank you so much
Hi Vikas, do u have any slides on LTE, as these slides are on VoLTE, or this playlist is good enough to learn both LTE and VoLTE?
Good presentation
thx u very much👍
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)
Very Nice
Vikas does a great job of taking complicated procedures and protocols in an understandable step-by-step fashion. One thing is for sure, you know your subject matter and know how to relate this to your audience. With my deepest gratitude, thank you!!
Vikas, I have one suggestion on the production side. The voice compression on your annunciations on your "s" sounds are sometimes a bit over-powering. It would be a fantastic idea to upgrade to a higher quality microphone. I use the Samson Stage PXD1, a wireless USB lapel microphone. It seems well balanced. You put a lot of work into your presentations, you deserve to have a really good microphone. Please don't get me wrong. You are a great speaker, and I can understand you very well. But the high-pitched ring caused by certain speech patterns limit the amount of time for continuous listening. Also, if you lower the volume on your intro music jingle, at the beginning of your videos, it will also be a significant improvement.
Brilliant explaination, presentation.....can you plz just make a video about fixing ims not registered issue
Mapping of 4G network with IMS and
the connectivity of network elements
of 4G with those of IMS?
This is a question which we got in class. Can you help on how to answer this question
thankyou sir
hi I have a question on xcap. Call barring.. Is there a way to have a chat with you mate?
Good IMS explanation Vikas sir....
Vikas Sir, please make video of Volte Call Flow with Message and their mandatory parameter(AVP).
Great
Nice
Thank you for the information can you please help me with the standard documentation for announcements flow in IMS by 3gpp
Will come up with VoLTE Advanced Series soon to cover all these topics .. Stay Tuned
Hi, Your vidoes are very nice for concepts. Inrefernce to this, our organization has given your website link for core employees to learn the VOLTE concepts.
Abhijeet Chowdhary is the BEST. He can’t be replaced by anyone.
This guy name is Vikas ... FYKI
thank you for your great work on IMS , could you please provide material pdf or ppt ?
Good idea give about ims core, application server and transport layer
Is there any videos for SIP?
IT'S GOOD VIDEO
Please make video on python & c Programming ,which is used in protocol development /testing with interview question.
why the P'CSCF is on the VPLMN?
You presented CSCF as P-I-S (CSCF). On VoLTE Architecture common scheme (11:45 min) there is no link betwen P-CSCF and I-CSCF. That's way P-S-I (CSCF) may be more correct for inderstanding. What do you think? In any case your video is so good. Thank you very much!
When USIM itself having binary (i.e. SIP user agent) capability of deriving IMPI and IMPU, then why we need ISIM?
what made ISIM more suitable for VoLTE? Awaiting for your reply.
Thanks.
ISIM carry a lot of Data specifically used in SIP protocols such as your IP Multimedia Private Identity (IMPI), domain, IP Multimedia Public Identity (IMPU) and cypher keys which makes it ready for VoLTE & Make it more secure
USIM does not have those kind of information. It has instead IMSI, SPN, Cyphering and Authentication keys used during registration in UMTS/LTE networks , It needs Binary to convert and extract IMPI & IMPU for use in VoLTE
TelecomTutorial info thanks for your reply sir
Can u make something for ims security. Overall
hi vikas can you do more videos on diameter protocol and PCRF
ahcha... thanks
Sir, Could u pls explain in hindi also....its much easier to others who wants to learn in hindi or searching in hindi @telecomtutorial
Can you please make a video in LTE explained in depth
Very nice explanation but some times your going a bit speed .. reading the sentences fast.
Sir, please provide one video for VOWIFI netchnology
Can u pls explain,what is meant by CODEC?
VoLTE uses RTP ( which is Real time transfer Protocol ) . This is widely used protocol for real time communications such as Voice or Video . RTP ensures Reliable delivery . As with any digital voice system, a codec must be used. The VoLTE codec is that specified by 3GPP is the adaptive multi-rate, AMR codec that is used in many other cellular systems from GSM through UMTS and now to LTE. As far as speech codecs are concerned for VoLTE , the basic Adaptive Multi Rate (AMR) speech codec is mandatory; the popular data rate for good speech quality is 12.2 kbps . AMR is old codec & in use since few Years now after 3G Era . RTP over UDP is used to transport AMR speech.
Kindly make this video in hindi for smooth understanding .Thanks in advance..
Users may be served by various sip server while only one sip server serves the customer.... did not understand this 😕
Can you give the pdf of 4g network.
✌️✌️✌️✌️👍👍👍
would you explain trans-coding little brief ? Grate video looking forward to watch other videos as well
Will come up with VoLTE Advanced Series soon to cover this .. Stay Tuned
@@TelecomTutorialinfo Great presentations Vikas,please keep up your good work and
can we have some sessions on Diameter protocol part in IMS & different IMS call flows which helps us to understand the AVP and other parameters of Diameter,when can we expect the VoLTE Advanced Series,eagerly waiting for this part as it is already more than an year when you had last updated about VoLTE Advanced Series,Thanks in Advance
Please add link to slides!!
Awesome Vikas ..I need some help .
1. Can some one tell me how many conformance test cases for each architecture element
2. Time it takes to run these test cases for each element of architecture
3. Preferred network simulator for each element of architecture .
Hi sir, is there any way that you have a flashcards or quizzes regarding this lesson? Very informative. Also it's good to have some strong sense of knowledge by answering questions. Thank you.
audio, not clear
I think u r practicing ur self..i couldn't able to understand what is going on
WE WANT ABHIJEET SIR BACK! IMS TEAM HAS LIED TO THEIR STUDENTS THAT HE’S BEEN SICK, ALL SUCH RUMOURS ARE NOTHING BUT “ BOGUS” BRING HIM BACK! WE DEMAND A REFUND!
Very bad audio 🙁
