Title:
METHOD AND DEVICE FOR HANDOVER OPTIMIZATION
Document Type and Number:
WIPO Patent Application WO/2024/029932
Kind Code:
A1
Abstract:
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. The disclosure provides a method and device for handover optimization. The method includes transmitting a first message to a second node, wherein the first message includes at least one of first candidate secondary cell group (SCG) primary cell (PSCell) list information, measurement report configuration information, and first master cell group (MCG) plus SCG configuration information. When Conditional Handover (CHO) + Conditional PSCell Addition or Change (CPAC) is combined, a success rate of CHO+CPAC handover is improved by optimization of candidate PSCell selection or optimization of CHO+CPAC execution conditions, thus ensuring a user equipment (UE) to select a suitable target cell, improving robustness and reliability of a UE handover, and further improving system throughput.
