Handover (HO): UE moves from one eNB to target eNB while keeping its connected state. 6. The UE periodically measures the Reference Signal Received LTE Cell Reselection is the idle-mode mobility procedure that moves the UE from one suitable cell to another without a connected handover. In order to perform cell selection and reselection in Multi-RAT (Multi-Radio Access Technology) 2G, 3G and 4G networks, we use combination between priority and ranking based. Cell Cell reselection procedures are used to change the cell that the UE is camped on after the UE goes into IDLE mode.
