Reply To: High SDCCH Assignment Failure


Hi All,
NSN,i have high SDCCH loss in a sector even the call volume is less,BSIC & BCCH for the cell is unique within the neighbor cells.i did the following actions but still there is SDLoss, please give me some idea.
1- before i have 2 SD TS on 2 different TRX and now on BCCH carrier ( SDCCH +SDCCB), but still SD loss.
2- swaped the BCCH freq. to another TRX but no use.
3- changed the BCCH freq. but still there is SDLoss.

Mean Holding time(sec) is 54 & TCH AVG Erlang is 3.
