GREAT, very helpful. sorry I just watched it now. I like the you explain the signaling message during HO. extraordinary and use conversation language instead of signaling language which is very difficult to understand. thanks dude
Thank you Ravikumar. We are trying to cover topics that may not be covered by everyone else; also happily promoting other channels with some good materials. Have a look at YedaCenter channel. It's a new channel but they have lots of stuff on IMS.
There is generally no packet loss during the handover as all the packets are buffered in the source eNB and transferred to target eNB at HO. If there are still some packets lost then they will be handled by IP layer.
Once the UE has handed over to the other RAT, the old packets are forwarded to the new RAT on downlink. In the Uplink, before handover the UE had already stopped sending data when the handover procedure started. You can check out a more detailed procedure here: blog.3g4g.co.uk/2011/03/lte-to-3g-handover-procedure-and.html
Soft handover (applicable in 3G only) is simpler. Here, only the access network changes while the core network remains the same and in control. Also, as soft handover is make before break, there is always an active connection so there is no packet loss. Let's say that there was some packet loss for any other reason, TCP will have to take care of the lost packets.
Very good explanation thank you very much ❤

Please explain other topics with the same way, like simple languages & animations dude
Anyway, do you know the difference between PRB & VRB in LTE?
Pl cover 4G/ims in detail. I mean basic call flows. No need to explain 3g/2g perspective. Thanks! Keep posting your content in short videos..

Only hard handover in 4G? Then how VoLTE call can be handed over?

Hello, how do you ensure no packets are lost during handover?
Once the UE has handed over to the other RAT, the old packets are forwarded to the new RAT on downlink. In the Uplink, before handover the UE had already stopped sending data when the handover procedure started.

@@3G4G5G thank you. I meant for soft handover?

What will core N/W do
