When an UE enters into a tracking area that is not present in the TAI list assigned during the attach/TAU procedure, UE initiates tracking area update procedure towards network. It comes under the non-periodic tracking area update procedure.
After UE handover to target ENB it sent RRC Connection Reconfiguration complete.why UE doing suddenly Tracking Area Update request? Even it is in RRC-Connected State.
On what basis UE decides whether it should trigger TAU procedure or not ?
