hi User_2010,
i know u’re using NOKIA, it is why i didn’t give you KPI names to check.
Just try to have KPI per TRX, it is the best solution for finding ur problem.
U said u have change SDCCH location from the BCCH TRX to another TRX; What is your config, i mean how many SDCCH did you define on this cell?
“RSSI detected Rxsignal difference exceeding threshold” i don’t know what it means , i’m not using NOKIA , but you should probably got a path unbalanced, look for HO causes and see if ur HO are due to low Uplink level or uplink quality too bad.
Thanks.
