OPERATION METHOD OF USER EQUIPMENT IN MULTI-CARRIER SYSTEM

摘要

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.

1. A User Equipment (UE) accessing a Long Term Evolution (LTE) wireless communication system operating a Multi-Carrier (MC), the UE comprising:
an access history identification unit configured to, when the UE accesses the LTE wireless communication system in a first frequency band on which the UE is camped, identify whether the UE stores an access fail history of the first frequency band by referring to an access fail counter for the first frequency band; a search unit configured to, when the UE stores the access fail history of the first frequency band,
receive a parameter indicating an accessibility to the LTE wireless communication system in a second frequency band, which is different from the first frequency band, andsearch for the second frequency band based on the received parameter; and an access control unit configured to, when the LTE wireless communication system is found in the second frequency band based on a result of the search, access the LTE wireless communication system through the second frequency band.
