Abstract
The invention provides a cell change method, a main node and user equipment, and relates to the technical field of wireless communication. The main node respectively sends auxiliary node adding request signaling to one or more auxiliary nodes, wherein the auxiliary node adding request signaling carries first continuous CPAC indication information; receiving an auxiliary node adding request response signaling fed back by the auxiliary node, wherein the auxiliary node adding request response signaling carries second continuous CPAC indication information; and sending a radio resource control (RRC) reconfiguration signaling to the user equipment, wherein the RRC reconfiguration signaling carries continuous CPAC configuration information. The user equipment is enabled to continuously execute CPAC based on the continuous CPAC configuration information, signaling overhead and time delay of PSCell flow change of the primary and secondary cells in an MR-DC scene are reduced, and user experience is improved.
