AR9406:AverageNumberofSampledOccupiedPDCHs(OverlaidSubcell)[2G]
Remark:
Last 2 counters can be used to calculate Busy PDCHs per 900/underlaidsubcell
And, hence, PS traffic per band (since no raw counters are available):
PS traffic per 900/underlaid= [PS Datavolume] *(1-[AR9406]/[AR9311])
PS traffic per 1800/overlaid= [PS Data volume] *( [AR9406]/[AR9311])
