The present disclosure proposes a method for managing a tracking area identity (TAI) list to be used by a user equipment (UE), a user equipment using the same, and a communication system using the same. The present disclosure would include a UE which stores a forbidden TAI list. A mobility management entity (MME) would transmit a first message which includes a TAI List to the UE. The UE would then determine whether the TAI list and the forbidden TAI list contain a first tracking area which is on both the TAI list and the forbidden tracking area list. If that is the case, the UE may either remove the first tracking area from the TAI list or the UE may remove the first track area from the forbidden tracking area list. After the revision of the TAI list is complete, the UE may synchronize the TAI with the MME.
