After an RRC connection is established between a first base station and a UE, a radio bearer for the UE is established in accordance with a service request from the UE. When determining that the UE meets a requirement on communication with second base stations whose types are different from the first base station, a dedicated configuration resource is allocated for the UE for enabling the UE to initiate a dedicated uplink detection signal. Dedicated second base stations are instructed to measure the dedicated uplink detection signal initiated by the UE, and one of the dedicated second base stations is allocated for the UE in accordance with measurement results. The UE is instructed to perform data transmission through the second base station allocated for the UE.
