Claim:
1. A method for transmitting traffic data for Always-on service over a paging channel (PCH), comprising: transmitting, by user equipment (UE, a radio resource control (RRC) connection establishment request indicating that the UE has a capability of bearing the PCH on a highspeed physical channel, to a NodeB; forwarding, by the NodeB, the RRC connection establishment request with an Enhanced Dedicated Channel (E-DCH) Radio Network Temporary Identifier (E-RNTI) assigned to the UE to a network control network element; assigning, by the network control network element, a HS-DSCH Radio Network Transaction Identifier (H-RNTI) to the UE after receipt of the RRC connection establishment request; transmitting, by the network control network element, a RRC connection establishment acknowledgement with the E-RNTI and the H-RNTI to the NodeB; forwarding, by the NodeB, the RRC connection establishment acknowledgement with the E-RNTI and the H-RNTI, to the UE; and entering, by the UE, the CELL-PCH state; determining, by a network side, that the UE has a capability of transmitting the PCH beared on a High Speed-Physical Downlink Shared Channel (HS-PDSCH); informing, by the network side, the UE of information of a traffic control information bearer channel through a paging identifier, when the UE is in a CELL-PCH state; listening, by the UE, for the traffic control information bearer channel; and receiving, by the UE, the traffic data for Always-on service on the traffic channel indicated by the traffic control information, wherein, the listening, by the UE, for the traffic control information bearer channel, and receiving, by the UE, the traffic data for Always-on service on a traffic channel indicated by the traffic control information comprises: listening, by the UE, according to a Paging Indicator Channel (PICH) identifier from the network side, for a HS-SCCH to perform synchronization; triggering, by the network side, a cell system information update through the HS-SCCH; instructing, by the network side, the UE to receive a BCCH on a High Speed Downlink Shared Channel (HS-DSCH): receiving, by the UE, the traffic data for Always-on service from the BCCH; wherein, instructing, by the network side, the UE to receive the BCCH on the HS-DSCH comprises: a first HS-SCCH listed on an update message ‘HS-SCCH system info’ transmitted by the Node B uses a BCCH specific H-RNTI to instruct the UE to receive the BCCH on the HS-DSCH.
