1. A serving secondary node, comprising:
at least one processor; and
at least one memory storing instructions, which, when executed by the at least one processor, cause the serving secondary node to:
receive, from a master node, first information indicating whether the serving secondary node is permitted to directly transmit a preparation request (PREP-REQ) to a target secondary node, wherein the preparation request indicates that an inter-secondary node conditional primary cell of a secondary cell group (PSCell) change is to be prepared;
determine, based on the first information, that the serving secondary node is permitted to directly transmit the preparation request to the target secondary node;
directly transmit, to the target secondary node, the preparation request;
directly receive, from the target secondary node, a preparation response via a signaling connection between the serving secondary node and the target secondary node; and
transmit, to a user equipment, configuration information (CFG-INF) related to the inter-secondary node conditional PSCell change over a signaling radio bearer using a radio interface of the serving secondary node.
