An embodiment of the present disclosure further provides a network communications method, including generating, by an RNC in an access network, first RRC signaling or first network signaling, and sending, by the RNC, the first RRC signaling to a UE or the first network signaling to a first base station in the access network, where the first RRC signaling is used to instruct the UE to add the first base station to an E-DCH active set of the UE, and instruct the UE to receive an E-HICH of the first base station, and the first network signaling is used to instruct the first base station to receive E-DCH data sent by the UE, and instruct the first base station to send the E-HICH to the UE, where, when the UE receives no DCH data from the access network, the first RRC signaling instructs the UE to disable a function of receiving an F-DPCH of the first base station, where the RNC completes the instruction by removing configuration information of the F-DPCH from the first RRC signaling or by setting a preset indication field in the first RRC signaling; or the first network signaling instructs the first base station to disable a function of sending an F-DPCH, where the RNC completes the instruction by removing configuration information of the F-DPCH from the first network signaling or by setting a preset indication field in the first network signaling; and when the UE receives DCH data from the access network, the first RRC signaling instructs the UE to disable a function of receiving a downlink DPDCH of the first base station, where the RNC completes the instruction by removing configuration information of a DPCH from the first RRC signaling or by using a preset indication field in the first RRC signaling; or the first network signaling instructs the first base station to disable a function of sending a downlink DPDCH, where the RNC completes the instruction by removing configuration information of a DPCH from the first network signaling or by setting a preset indication field in the first network signaling.
