Dear expert

We are facing some issues one BSC,
1. Most of cells in BSC have very high TCHHR drop and high failure in the Incoming HO on the DCS 1800 Trx overlaid ( commen BCCH cells) and during the Busy hour ,although DCS1800 Band is less interfered than EGSM 900 the not congested and don’t have path balance issue . 2. We had very high TCHHR drop in some cells on DSC1800 TRx’s ,once we disable the HR the DCR decreased from 2000 to 100 drop .
could you pls tell me what is the reason behain this "our vender Huawei "
