Abstract: The present invention is about conditional handover (CHO) in telecommunications networks, and a main point is to pass the responsibility to a target Master Node for triggering the UE to rapid access to Primary Secondary Cell after applying target Primary Cell configuration during a CHO-NR-DC handover. The target MN decides whether to wait further to execute CPC. If measurements are hopeful, completion of execution of the primary secondary cell for dual connectivity is postponed, and L3 measurement results are inspected from the UE. There are three variants, when the target MN requests the UE to access the target Secondary Node; namely RRC-based access target SN trigger, PDCCH-order-based variant and DL MCE-based variant.

Abstract: According to an aspect, there is provided an apparatus configured to perform the following. The apparatus performs radio measurements of one or more primary cells, PCells, and of primary secondary cells, PSCells, associated with the one or more PCells. Then, the apparatus evaluates a conditional handover, CHO, execution condition of the one or more PCells and a conditional PSCell addition/change, CPAC, execution condition of the PSCells based on the radio measurements. At least in response to the CPAC execution condition for a first PSCell being satisfied while the CHO execution condition for any PCell associated with the first PSCell is not satisfied, the apparatus relaxes or stops radio measurements of at least one PSCell.
