Hi harshita,

Yes it is mandatory to do TAU after handover if the target ENB TAC is not part of TAI_list which UE has. If target ENB is part of TAI-list then there wont be any TAU from UE.

Yes it is needed as after X2 handover where MME is not involved, MME does not know the location of UE if it happens to be in a different TA.
