TAI is not being used to locate a particular eNodeB(target eNodeB). TAI sends inside Handover required message, is used by source MME. It might be possible that target enodeB is not served by source MME but still belongs to tracking area which is served by source MME. In that case, S10 interface based handover comes into picture. Please refer 29.274 specification. Even this TAI helps to find suitable target SGW.

So that we can identify particular EnodeB.

LTE: How source eNodeB get to know when it has to trigger handover required message towards MME ?

I have basic handover related query. How source eNodeB get to know when it has to trigger handover required message ? I mean to ask, how a source eNodeB come to know the threshold values of RSRP or RSRQ or both (related to target eNodeB) , required to do a successful handover towards eNodeB ? Is it due to network planning ?

LTE handover: Why does "TAC" required as part of "Target Id" IE within the forward relocation request message ?

In case of S1-handover with the MME relocation, source MME sends an information "Target Identification" to target MME.
What the target MME does by receiving TAC, when an enodeb can be identified uniquely by using combination of (PLMN + Macro/Home ENodeB) ?

Can someone tell me what the purpose behind to send TAC as part of Target Id IE ?
