Further, the second receiving module 24 is configured to, after the sending module 22 sends the instruction information to the UE, receive a fourth measurement report sent by the UE, where the fourth measurement report is sent by the UE to the RNC when the common pilot channel quality of the macro base station is greater than the second condition threshold value for addition to the second active set. The sending module 22 is further configured to send third control information to the UE, so that the UE adds the macro base station to the second active set according to the third control information.
Alternatively, the second receiving module 24 is further configured to, after the sending module 22 sends the instruction information to the UE, receive a fourth measurement report sent by the UE, where the fourth measurement report is sent by the UE to the RNC when the common pilot channel quality of the macro base station is less than the fourth threshold value. The sending module 22 is further configured to send fourth control information to the UE, so that the UE removes the macro base station from the third active set according to the fourth control information.
