An X2 Handover is used by LTE as well as S1 handovers for User Equipment (“UE”) or mobile phone mobility. However the IP link will not move although an you can switch from NodeBs, meaning that any soft-handover or hard-handovers that occur between NodeBs does not affect the GTP-U link form the internet to the UE.
The hysteresis can be configured with a value between 0 and 30 dB. Event A3. The LTE Event A3 is triggered when a neighbouring cell becomes better than the serving cell by an offset. The offset can be either positive or negative.
