According to example embodiment, a method may include transmitting, by a master node (MN) to a target-secondary node (T-SN), a request for the target-secondary node (T-SN) to prepare a set of one or more candidate target primary cells of a secondary cell group (candidate target PSCells) for a conditional PSCell change for the user device; and transmitting, by the master node (MN) to a source-secondary node (S-SN) that provides dual connectivity for a user device, information indicating or relating to an arrival probability of a cell change for the user device to the target-secondary node (T-SN).
