When the "Last Visited TAI" is available at the UE , it includes this available information within the attach and tracking area request messages. After receiving this "Last visited TAI" list information, MME prepares better TAI list and sends back to the UE by using the attach accept or the tracking area accept message.

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 ?
