One basic difference what I know that If target RAT is prepared I mean to say if SRBs and DRBs data are already established at target network then source network triggers handover towards UE otherwise it triggers cell change order for that UE.
When an UE moves from one cell to another cell of same eNodeB then what are all messages exchanged between UE and eNodeB as per specification ? Here I have assumed macro eNodeB.
what is difference between UEID IE of rrc connection request and IMSI ?
