Hi Pix,
Hi experts,
I was on vacation
Well, for the cells suffering from high DL_TBF_drop (%), i changed below parameters as follows:
1/ CS-INIT = CS-2
2/ IMCSUL8PSK = MCS2 (Initial MCS uplink 8PSK)
3/ IMCSULGMSK = MCS2 (Initial MCS uplink redundancy GMSK)
3/ INIMCSDL = MCS3(Initial MCS downlink)
4/ LINK ADAPTATION (LA) = TRUE
5/ Both EGPRS & GPRS are activated
6/ Uplink Incremental Redundancy = TRUE
Unfortunately, all these changes did’nt bring any results, drop rate still the same, knowing that all cells frequency are clean (no interference)
PLZ, ur advice
thx
