Hi,

For Ping Pong Handover,Please check the following points.

1. Check the neighbour, all neighbour should be defined properly2. Check the drivetest coverage, it could be caused by no dominance server or interference, so adjust antenna is one of the solution3. Parameter consistency check, HO margin, ADJRXLEVELMIN, neighbouring priority GSM DCS, etc. for example HO for DL RxLevel is set to -95 dBm so the AdjRXLEVELMIN should be more than -95 dBm eg -90 dBm
