Patent ID: 8792894

Claim:
A method for implementing energy saving control at a NodeB, comprising: when a Radio Network Controller (RNC) determines a cell of a NodeB is required to sleep, the RNC sending an indication of sleeping the cell to the NodeB, and the NodeB sleeping said cell to enter into an energy saving state; and when the RNC determines the cell of the NodeB is required to wake up, the RNC sending an indication of waking up a cell to the NodeB, and the NodeB waking up said cell to exit the energy saving state wherein the step of said RNC sending an indication of sleeping the cell to the NodeB, and the NodeB sleeping the cell comprises: the RNC sending an energy saving control indication to the NodeB to instruct the NodeB to sleep the cell friendly; the NodeB switching users in the cell required to sleep into other cells; and the NodeB sleeping said cell; wherein the step of said RNC sending an indication of waking up the cell to the NodeB, and the NodeB waking up said cell comprises: the RNC sending an energy saving control indication to the NodeB to instruct the NodeB to wake up the cell immediately; and the NodeB recovering a working state value of pilot channel power of a carrier of the cell; wherein a cell reconfiguration request message is used to carry said energy saving control indication; a cell reconfiguration response message is used to indicate that energy saving control process is successful; and a cell reconfiguration failure message is used to indicate that energy saving control process is failed, wherein the cell reconfiguration failure message carries a failure cause indicating that energy saving control fails; or, an energy saving control indication message is used to carry said energy saving control indication; an energy saving control response message is used to indicate that energy saving control process is successful; and an energy saving control failure message is used to indicate that energy saving control process is failed.
