Abstract
Provided is a channel detection notification method when a LTE system works at an unauthorized frequency band, a system and a base station. The channel detection notification method includes the follows. A primary cell base station receives RRM measuring results of multiple base stations at the unauthorized frequency band reported by a terminal; according to the RRM measuring results of the multiple base stations, a secondary cell base station is selected for the terminal; if it is determined that downlink traffic reaches a set first traffic threshold value, the secondary cell base station is informed to conduct downlink channel detection at the unauthorized frequency band; and if it is determined that uplink traffic reaches a set second traffic threshold value, the secondary cell base station and/or the terminal is informed to conduct uplink channel detection at the unauthorized frequency band.
