DETECTING AND REDUCING PING-PONG HANDOVER

WIPO Patent Application WO/2023/159460

A1

The UE may store target cell information to a database based on performing a handover to the target cell and detecting the ping-pong handover based on a number of handover instances in the database of the target cell to which the UE has performed the handover being greater than or equal to a threshold number of the handover instances within a period of time. The UE may receive, from a base station a list of ping-pong cell candidates and configure the number of handover instances of the target cell and/or the period of time based on the list of ping-pong cell candidates. The UE may avoid or reduce the handover to the identified ping-pong cell based on the detected ping-pong handover by applying an offset to the measurement of the target cell.
