An information configuration method, comprising: receiving, by a terminal, first configuration information sent by a target base station, the first configuration information comprising multiple Secondary Node, SN, configurations; selecting, by the terminal based on signal measurement results of cells in an inactive state, an SN configuration from the multiple SN configurations as a target SN configuration; sending, by the terminal, index information corresponding to the target SN configuration to the target base station, to enable the target SN configuration to be in an active state, wherein each SN configuration comprises configuration information of a plurality of cells, and the terminal determines a cell in the plurality of cells to be a Primary Secondary Cell, Pscell, of a respective SN; and wherein when the target SN configuration is in the active state, in the target SN configuration, the Pscell determined by the terminal is in the active state, and a Secondary Cell, Scell, determined by the terminal is in the inactive state; and sending, by the terminal, to the target base station at least one of: the signal measurement results of cells in the inactive state, or identification information of the Pscell determined by the terminal in the target SN configuration, wherein the signal measurement results of the cells in the inactive state are used to trigger the target base station to transmit an activation command for at least one Scell in the target SN configuration. receiving, by a terminal, first configuration information sent by a target base station, the first configuration information comprising multiple Secondary Node, SN, configurations; selecting, by the terminal based on signal measurement results of cells in an inactive state, an SN configuration from the multiple SN configurations as a target SN configuration; sending, by the terminal, index information corresponding to the target SN configuration to the target base station, to enable the target SN configuration to be in an active state, wherein each SN configuration comprises configuration information of a plurality of cells, and the terminal determines a cell in the plurality of cells to be a Primary Secondary Cell, Pscell, of a respective SN; and wherein when the target SN configuration is in the active state, in the target SN configuration, the Pscell determined by the terminal is in the active state, and a Secondary Cell, Scell, determined by the terminal is in the inactive state; and wherein each SN configuration comprises configuration information of a plurality of cells, and the terminal determines a cell in the plurality of cells to be a Primary Secondary Cell, Pscell, of a respective SN; and wherein when the target SN configuration is in the active state, in the target SN configuration, the Pscell determined by the terminal is in the active state, and a Secondary Cell, Scell, determined by the terminal is in the inactive state; and sending, by the terminal, to the target base station at least one of: the signal measurement results of cells in the inactive state, or identification information of the Pscell determined by the terminal in the target SN configuration, wherein the signal measurement results of the cells in the inactive state are used to trigger the target base station to transmit an activation command for at least one Scell in the target SN configuration.
