Abstract

The present invention relates to a method, system and UE for state transition. The method includes: after a transition from the CELL-PCH state to the CELL-FACH state, a UE receives the scheduling control channel continuously, or receives simultaneously the scheduling control channel according to the receiving time corresponding to the DRX mechanism when the UE is in the CELL-FACH state and the receiving time corresponding to the DRX mechanism when the UE is in the CELL-PCH state; after obtaining an indication of normal reception, the UE receives the scheduling control channel according to the receiving time corresponding to the DRX mechanism when the UE is in the CELL-FACH state; the radio network controller has be informed that the UE has transited from the CELL-PCH state to the CELL-FACH state simultaneously when the UE obtains the indication of normal reception, so as to avoid data loss in a certain period after the state transition of the UE.
