In the handover required message, there is an IE target TAI. How source eNodeB came to know TAI of target eNodeB ? Is it configurable parameter or UE report as part of handover or something else.

All the time UE makes a measurements
This is to trigger Handover to different TA or to Inter-RAT Handover or going few levels down to to monitor if they dont have to change the transmitting power.
Many measurements.

I'm not the radio person, but I'm sure one of the logical channels provides the information on what neighboring eNBs are serving.
Information like PLMN-ID, TAC/TAI and probably many many more.

During the never-ending measurements UE is aware of neighboring cells, their GCI and TAI/TAC.

Please check "MeasResultEUTRA" IE. It has tracking area code of target eNodeB.

How target enodeb will validate the new incoming user during x2 or s1 handover?

How target enodeb will confirm if the incoming user is a genuine user or not?

Is there any IE exchanged during HO preparation phase? I am expecting that during X2 handover AS SECURITY INFO in UE context is very helpful? Is that or not?
