We have NSN provider RG20 version in 2G
We have activated DL PC on a BSC with those thresholds (qual between 0&3,level -70 -85)
TGhe first feedback is no improvement of CS/PS KPI’s at all but increase of DL level rate by 5% (reduced from better cell rate)
The DL level HO threshold is varibale per cell and the lowest one is -90 so far enough from lower threshold,
What do you advice?9th July 2013 at 14:38 #69134PixGuest
Try to increase the reactivity of your DL PC (shorter averageing window, no waiting time between PC Commands & PC Ack)
Could you see if the number of DL LEV HO has increased or if the number of BC HO has reduced ?
Later,Try level -67 -829th July 2013 at 22:28 #69135SlimGuest
many thanks for the reply
Yes the number of DL level HO has increased and the number of HO BC has reduced
The PC average window is 4
For HO is 8
What I can not understand in PC aârt from level HO increase is the following:
Taking into account that PC decrease commands are bigger than increase ones by almost 3 times , this means that less interference is existing so why SDR,CDR,TBF drop … don’t go down whatever is the upper lower thresholds???18th July 2013 at 19:38 #69136pixGuest
Maybe you don’t have so much DL interference to begin with ?
The decrease/increase size is only impacting on the reaction time of the system. A huge amount of commands (inc and dec) will be used during the call in order to achieve the desired DL RXLEV at all time.
Try increasing your rxlev upper and lower threshold by +3dB.
