Hi Gaurav, Nice Video man. Explaining all architectures on the same page helped in spotting differences and similarities. It was short but informative. I really appreciate your efforts. Thanks

Thank you so much buddy

[@Ravishukla1291]

Bahut accha ,,,,helpful

[@Shafashe2oo]

Good job

[@jamesraj6531]

1.Direct tunnelling is RNC to GGSN
2.Gs interface is between SGSN and MSC
3.In 2G/3G its MS not UE.
4.interface b/w mobile & Node b is Uu.
5.Interface b/w MME & HSS is S6a not S6d.
6.Rx interface is b/w PCRF & AF.
All other good

[@jagdishnikam7608]

Thanks for such knowledge sharing video, Good explanation appreciate if u include volte nodes and explain call flow in detail

[@HemantPurohit-w4e]

Hello Gaurav. You explained really in a clear and concrete way. Could you please share the differences in interfaces of VoLTE/LTE and 5G architecture? If there are any slides for VoLTE and 5G interfaces ?

Nice Video but Small correction Bro:

2. Air interface b/w mobile & Node b is Uu not Um.
3. Interface b/w MME & HSS is S6a not S6d.
4. Rx interface is b/w PCRF & AF(Application function server) not PCRF & ISP.

[@andrearahmandita7047]

[@mjtechstar9992]

Well explained Gaurav

[@tanjirahmed6643]

The background music spoiled the whole video

MME to HSS interface is S6a, S6d is correct for SGSN to HSS.. good explanation.. it will be good if end to end call flow explanied

[@gauravbhatt1960]

oh i missed that ,thanks for that

[@adyaandagastyasharma3202]

Back ground music and noise are very disturbing, your voice is not properly heard

[@shaikshukur7110]

can u please explain 2g,3g and 4g GPRS attach procedure

[@gauravbhatt1960]

yes all interfaces

[@pranayt1]

Bhai asa kya page bacha rahe ho !

[@sayanbagchi8891]

Can you please make a proper video of only 4g call flow?

[@srinivaspampana9568]

[@adr_4n]

Hi Gaurav, in 4G could you please also explain the IMS part?

[@gauravbhatt1960]

soon we will update that also

[@mohammadrezaghadami6361]

Amazing Video!!!!! appreciate if you can talk about SS7 protocol and especially MTP3 and GT dpc and related routing. Thanks

[@gauravbhatt1960]

soon we will update that also

[@mmaa5109]

Why the annoying music! Its louder than Your voice

[@travelfreak18]

Background music bnd kro

[@gunapreethi4210]

Back ground Music is dominanting than your voice..

[@gauravbhatt1960]

sorry noted next time we will update that also

[@raghavsamba]

Is call flow and architecture the same

[@vossti]

Not necessarily. Architecture remains pretty much unchanged while call flow differs from situation to the next; e.g calling B number in the same VLR will be different slightly if another VLR is involved.. Calling another plmn or while roaming- the call flow changes also slightly.

[@raghavsamba]

@@vossti OK got it.. Thank u

[@fatumaahemed134]

Too much background noise can't hear you😢

[@sureshchandra-jn3mc]

Please add one more...

soon we will update more waiting for response

[@andrearahmandita7047]
