I am not sure, that I understood what your problem is. You were written that in yours network is a lot of HO due to Uplink. From your settings: HO THRESHOLDS LEV UL RX LEVEL ………… -095 dBm. We are using lower level. From statistic, measurement and calculation path loss is UL much more critical for communication in GSM. My suggestion is to set HO Threshold for UL lower than DL (5dB).
We have same handover priority according HO criteria. My note to increasing number HO due to Quality is from my experiences.
