3G Intra Freq Handover

Hello team.
I’m facing an issue trouble shooting main causes of intra freq HO failure in 3G. Already i have a particular cell whose network performance is seriously degrading and i’ve checked if any alarm is available, and site availability as well but no issue found. Equally i’ve checked UL RSSI but seems ok. Please can someone provide clues or other things to check inorder to find main cause of this high Intra freq HO failure ?

you can check if there is any mismatch between srnsContainer release in relocation command.
