  • Publication number: 20240064590
    Abstract: A method for automatically measuring a handover performance in a multi-cell environment includes: by a base station device, transmitting a radio frequency (RF) signal; rotating by one full rotation; receiving a first measurement dataset from a user equipment (UE); obtaining a first trigger value and a second trigger value based on the first measurement dataset, and calculating a third trigger value based on the second trigger value and a preset third event offset value; transmitting a plurality of RF signals; rotating by a preset angle with a preset angular velocity; receiving a second measurement dataset from the UE; transmitting a command to the UE to perform a handover process; and measuring a plurality of results associated with the handover process. The results include a handover time during which the handover process is implemented and completed, and a success rate of the handover process.
