Title:
CONDITIONAL HANDOVER METHOD, APPARATUS AND DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/188890
Kind Code:
A1
Abstract:
Embodiments of the present application provide a conditional handover method, apparatus and device, and a storage medium. The method comprises: when a terminal in a dual-connectivity mode performs a conditional handover, the terminal is handed over from a first master base station to a second master base station; the terminal obtains a candidate cell list, and sends the candidate cell list to the second master base station, the candidate cell list representing a secondary cell group configured when a first secondary base station configures a conditional PScell change (CPC) configuration on the terminal, wherein the candidate cell list is used for the second master base station to establish a communication interface with each cell in the candidate cell list when the second master base station reserves the first secondary base station, so that the second master base station and the first secondary base station together provide dual-connectivity services for the terminal.
