Zusammenfassung:Disclosed is a User Equipment (UE) accessing a Long Term Evolution (LTE) wireless communication system operating a Multi-Carrier (MC). The UE includes: an access history identification unit, when the UE accesses the LTE wireless communication system in a first frequency band on which the UE is camped, identifies whether the UE stores an access fail history of the first frequency band; a search unit, when the UE stores the access fail history of the first frequency band, receives a parameter indicating an accessibility to the LTE wireless communication system in a second frequency band, and searches for the second frequency band based on the received parameter; and an access control unit, when the LTE wireless communication system is found in the second frequency band based on a result of the search, accesses the LTE wireless communication system through the second frequency band.
