[@sivaramakrishnarajuvegesna381]

Amazing video well explained about all the interfaces.. hats-off dude

[@gauravbhatt1960]

thanks for that buddy

[@maravivarma]

Good one to understand the basics of call flow in various technologies. Appreciate if you can do it on a whiteboard and include the VoLTE and CSFB

[@josephstanleyxavier7655]

Amazing video we are expecting lot from you

[@gauravbhatt1960]

thanks for your support!! many more coming soon

[@keerthikarthik3679]

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

[@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

[@ashish9945]

Awesome video bro

[@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 ?

[@jagdishnikam7608]

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

[@AbdulRehman-nz4rg]

good explanation in shortest possible time.

[@jalajmishra4340]

[@Astrochaitanya]

Nice Video but Small correction Bro:
1. In 2G/3G its MS not UE.
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]

Yes you right

[@RandomVideos-zr7zc]

Good explanation but in 4G instead of RAN should be E-UTRAN. correct me if i am wrong.

[@athipatlamuralikrishna5233]

Hi, Thanks for the video.
Gp is the interface between SGSN to GGSN in Roaming scenario, but not in between SGSN To SGSN.

[@gauravbhatt1960]

Athipatla Murali Krishna gp is also for any other plmn shan or ggsn

[@gauravbhatt1960]

yes all interfaces

[@shaikshukur7110]

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

[@jokerdjking3367]

Thanks a lot

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

[@madhuribhatt4552]

Boring.please add recipes of butter chicken...

[@pranayt1]

Bhai asa kya page bacha rahe ho !

[@sureshchandra-jn3mc]

Please add one more...

[@gauravbhatt1960]

soon we will update more waiting for response

[@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😢

[@mmaa5109]

Why the annoying music! Its louder than Your voice

[@gauravmishra4442]

[@srinivaspampana9568]

Music avasarama

[@vixitsharma]

Remove that background music
