As per my understanding, We are able to locate UE with the use of TAI then what is the use of ECGI?

TAI is per operators choice, while ECGI is one for cell.
So
Operator1: TAI 1+ECGI
Operator2: TAI 2+ECGI

Difference between TAI and ECGI are
1. TAI is plmn+TAC and ecgi is plmn +cellid(eNodeBid).
2. In connected mode UE location is know at cell level to core network.
3. In Idle mode UE location is known at TAI level to core network

Uplink NAS transport message is used between eNodeB and MME to pass NAS messages between UE and MME transparently.
Since eNodeB has already communicated TAI and E-CGI as part of "Initial UE message" and MME knows current serving (cell and tai ) of UE then why both IEs are mandatory in Uplink NAS transport. I think it should be optional and it should be included in the message when there is a change in serving (cell or tai or both).

Need clarity on following items:
1. What is the use of "UE selected plmn" information for an eNodeB ?
2. Is the ECGI/TAI constructed based on the primary plmn (PLMN broadcasted in 0th index in SIB1 ) or based on the UE selected PLMN ?
