A method of updating a radio link parameter for a radio communications system having a network controller, a base station connected with the network controller, and a user terminal, in communication with the base station, the method comprising: when the base station needs to update the radio link parameter, it triggers the radio link parameter updating by sending by the base station to the network controller parameter information to initiate update of the radio link parameter through a message between the base station and the network controller, wherein the radio link parameter is a high speed downlink packet access, HSDPA, related parameter for high speed downlink shared channel, HS-DSC, and the base station includes a Medium Access Control-high speed, MAC-hs, sub-layer, which manages a HS-DSCH, wherein the HS-DSCH is a transport channel and is mapped to a high speed physical downlink shared channel, HS-PDSCH, wherein the parameter information is related to a High Speed-Dedicated Physical Control Channel, HS-DPCCH, and wherein the parameter information includes at least one of a channel quality indicator, CQI, feedback cycle information, and a CQI repetition factor information of the user terminal, and wherein the message is sent to the network controller from the base station. when the base station needs to update the radio link parameter, it triggers the radio link parameter updating by sending by the base station to the network controller parameter information to initiate update of the radio link parameter through a message between the base station and the network controller, wherein the radio link parameter is a high speed downlink packet access, HSDPA, related parameter for high speed downlink shared channel, HS-DSC, and the base station includes a Medium Access Control-high speed, MAC-hs, sub-layer, which manages a HS-DSCH, wherein the HS-DSCH is a transport channel and is mapped to a high speed physical downlink shared channel, HS-PDSCH, wherein the parameter information is related to a High Speed-Dedicated Physical Control Channel, HS-DPCCH, and wherein the parameter information includes at least one of a channel quality indicator, CQI, feedback cycle information, and a CQI repetition factor information of the user terminal, and wherein the message is sent to the network controller from the base station. sending by the base station to the network controller parameter information to initiate update of the radio link parameter through a message between the base station and the network controller, wherein the radio link parameter is a high speed downlink packet access, HSDPA, related parameter for high speed downlink shared channel, HS-DSC, and the base station includes a Medium Access Control-high speed, MAC-hs, sub-layer, which manages a HS-DSCH, wherein the HS-DSCH is a transport channel and is mapped to a high speed physical downlink shared channel, HS-PDSCH, wherein the parameter information is related to a High Speed-Dedicated Physical Control Channel, HS-DPCCH, and wherein the parameter information includes at least one of a channel quality indicator, CQI, feedback cycle information, and a CQI repetition factor information of the user terminal, and wherein the message is sent to the network controller from the base station.
