1. A dual/multi-connectivity-based secondary node addition/replacement method, comprises:
receiving configuration information of one or more Secondary Nodes, SNs, sent by a Master Node, MN;
performing a measurement evaluation on the one or more SNs according to the configuration information of the one or more SNs to determine an SN satisfying a connectivity condition;
initiating a random access process to the SN satisfying the connectivity condition, and simultaneously notifying the MN of the SN satisfying the connectivity condition through an RRC reconfiguration complete message sent to the MN; or simultaneously notifying the MN of the SN satisfying the connectivity condition through an SN access request/notification/instruction message separately sent to the MN;
wherein the receiving configuration information of one or more Secondary Nodes, SNs, sent by a Master Node, MN, comprises:
receiving an RRC reconfiguration message sent by the MN after extracting or separately cascading the configuration information of one or more SNs.
