A method for transmitting traffic data over a paging channel comprising: transmitting, by a user equipment, UE, a radio resource control, RRC, connection establishment request to a NodeB, the RRC connection establishment request indicating that the UE has a capability of bearing a paging channel, PCH, on a high speed physical channel; 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 High Speed Downlink Shared Control Channel, 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, an 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; entering, by the UE, the CELL-PCH state; determining, by a network side, that the UE has a capability of bearing the PCH 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 the PCH state, which comprises informing, by the network side, the UE of information of the traffic control information bearer channel through the paging identifier, when the UE is in the CELL-PCH state or in a UTRAN Registration Area paging channel, URA_PCH, state; and listening for the traffic control information bearer channel and receiving the traffic data on a traffic channel indicated by the traffic control information, by the UE, which step comprises: listening, by the UE, according to a Paging Indicator Channel, PICH, identifier from the network side, for a High Speed Shared Control Channel, 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 Broadcast Control Channel, BCCH, on the HS-SCCH; and receiving, by the UE, the traffic data from the BCCH. transmitting, by a user equipment, UE, a radio resource control, RRC, connection establishment request to a NodeB, the RRC connection establishment request indicating that the UE has a capability of bearing a paging channel, PCH, on a high speed physical channel; 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 High Speed Downlink Shared Control Channel, 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, an 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; entering, by the UE, the CELL-PCH state; determining, by a network side, that the UE has a capability of bearing the PCH 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 the PCH state, which comprises informing, by the network side, the UE of information of the traffic control information bearer channel through the paging identifier, when the UE is in the CELL-PCH state or in a UTRAN Registration Area paging channel, URA_PCH, state; and listening for the traffic control information bearer channel and receiving the traffic data on a traffic channel indicated by the traffic control information, by the UE, which step comprises: listening, by the UE, according to a Paging Indicator Channel, PICH, identifier from the network side, for a High Speed Shared Control Channel, 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 Broadcast Control Channel, BCCH, on the HS-SCCH; and receiving, by the UE, the traffic data from the BCCH. listening, by the UE, according to a Paging Indicator Channel, PICH, identifier from the network side, for a High Speed Shared Control Channel, 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 Broadcast Control Channel, BCCH, on the HS-SCCH; and receiving, by the UE, the traffic data from the BCCH.
