During all types of handovers (X2, S1 handover with MME relocation, S1 handover with SGW relocation or even both can be changed ) PGW never changed for LTE since allocated IP address for an UE should be retained while moving from one place to another place.

That's what I was also thinking (but not responded as I was not sure), but can there be a possibility of two PDN terminating in the same PGW and handover is between two PDN (no PGW change). Though very hypothetical scenario.

I have worked in LTE technology and observed the data rate through LTE network. We know , LTE deployment is on going and it will take few years to roll out completely in India. When a LTE UE attaches to network and handover to UMTS due to mobility then is there any change in data rate ? If yes, then how this change is communicated to UE. I mean to say what signalling messages exchange in network ?

Please suggest some pointer about Lte to UMTS/GERAN network handover -
1. Which are the interfaces got involved.
2. What is the role of diameter (interface) specifically.
3. If call is Voice (VoLTE) then is there any impact.
