In another implementation manner of the method, when the UE receives DCH data from the access network, that the second RRC signaling is used to instruct the UE to receive a downlink DPDCH sent by the first base station further includes that the second RRC signaling instructs the UE to receive a downlink DPCCH sent by the first base station.
In another implementation manner of the method, the method further includes that, when the UE receives no DCH data from the access network, the second RRC signaling includes configuration information of the F-DPCH; and when the UE receives DCH data from the access network, the second RRC signaling includes configuration information of the downlink DPCH of the first base station.
In another implementation manner of the method, the method further includes that generating, by the RNC, second network signaling, and sending, by the RNC, the second network signaling to the first base station, where: when the UE receives no DCH data from the access network, the second network signaling is used to instruct the first base station to send the F-DPCH to the UE; and when the UE receives DCH data from the access network, the second network signaling is used to instruct the first base station to send the downlink DPDCH to the UE.
In another implementation manner of the method, when the UE receives DCH data from the access network, that the second network signaling is used to instruct the first base station to send the DPDCH to the UE further includes that: the second network signaling instructs the first base station to send a downlink DPCCH to the UE.
