When a LTE user moves to UMTS network through handover, Is there any change occur in ongoing sessions ?

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 ?
