A communication method, comprising: acquiring, by a secondary network node, a network state of a cell served by the secondary network node; updating, by the secondary network node, a network configuration of the cell served by the secondary network node according to the network state of the cell served by the secondary network node; and sending, by the secondary network node, first update configuration information to a terminal, wherein the first update configuration information is used for updating the network configuration of the cell served by the secondary network node, wherein the network state of the cell served by the secondary network node comprises: signal quality of a signal transmitted between the cell served by the secondary network node and the terminal; wherein the signal quality of a signal transmitted between the cell served by the secondary network node and the terminal is measured autonomously by the secondary network node, and the signal quality of a signal transmitted between the cell served by the secondary network node and the terminal comprises Reference Signal Receiving Power, RSRP, or reference signal receiving quality, RSRQ; wherein, when the secondary network node updates the network configuration of the cell served by the secondary network node according to the network state of the cell served by the secondary network node, the secondary network node does not need to perform signaling interaction with a primary network node. acquiring, by a secondary network node, a network state of a cell served by the secondary network node; updating, by the secondary network node, a network configuration of the cell served by the secondary network node according to the network state of the cell served by the secondary network node; and sending, by the secondary network node, first update configuration information to a terminal, wherein the first update configuration information is used for updating the network configuration of the cell served by the secondary network node, wherein the network state of the cell served by the secondary network node comprises: signal quality of a signal transmitted between the cell served by the secondary network node and the terminal; wherein the signal quality of a signal transmitted between the cell served by the secondary network node and the terminal is measured autonomously by the secondary network node, and the signal quality of a signal transmitted between the cell served by the secondary network node and the terminal comprises Reference Signal Receiving Power, RSRP, or reference signal receiving quality, RSRQ; wherein, when the secondary network node updates the network configuration of the cell served by the secondary network node according to the network state of the cell served by the secondary network node, the secondary network node does not need to perform signaling interaction with a primary network node. signal quality of a signal transmitted between the cell served by the secondary network node and the terminal; wherein the signal quality of a signal transmitted between the cell served by the secondary network node and the terminal is measured autonomously by the secondary network node, and the signal quality of a signal transmitted between the cell served by the secondary network node and the terminal comprises Reference Signal Receiving Power, RSRP, or reference signal receiving quality, RSRQ; wherein, when the secondary network node updates the network configuration of the cell served by the secondary network node according to the network state of the cell served by the secondary network node, the secondary network node does not need to perform signaling interaction with a primary network node.
