UL Voice Quality improvement - 2G

[nandi_saikat1]

Hi Experts,

Please help.
Physical optimization completed. It's Jamshedpur NW in India/Bihar. AMSL variation is very high. It's ZTE 2G NW.
Presently, POC for UL lev has been define as -78 to -86 and for DL -75 to -85 with P/N as 1/2; POC quality has been defined as 0 to 2 for UL & DL with1/2 criteria; HO will trigger at -95 lev and Quality as 2 for UL & DL with 2/3 criteria to be fulfilled. -90 is the lev to be a candidate for HO (rxlevmin); With this settings my UL quality is 96.8%.
Huge pressure is to improve the same up to 97.5%. Please suggest.

Have gone through with disabling of AMRF and using EFR, Voice quality improvement will be followed tomorrow. Let me see, if the same thing happens with ZTE system or not.

Rgrds,
