Hi Guys,

I'm newbie in 3G. Could you please tell me what counters should I check to detect IUB congestion on the node. Transport type is ATM.



Thanks

For AAL2 path on Iub
Aal2PathVccTp::pmEgressCpsPackets
Aal2PathVccTp::pmDiscardedEgressCpsPackets

Congestion per AAL2 Path [%]= 100*pmDiscardedEgressCpsPackets/(pmEgressCpsPackets+pmDiscardedEgressCpsPackets)

HSDPA congestion indication over Iub
IubDataStreams::pmHsDataFramesLostSpiXX
IubDataStreams::pmHsDataFramesReceivedSpiXX

HSDPA Frame Loss [%] = 100* pmHsDataFramesLostSpiXX / (pmHsDataFramesReceivedSpiXX+pmHsDataFramesLostSpiXX)

Hi vika76,

are you sur about your formula?
HSDPA Frame Loss [%] = 100* pmHsDataFramesLostSpiXX / (pmHsDataFramesReceivedSpiXX+pmHsDataFramesLostSpiXX)
I saw in E******* document = 1000 *pm... and not 100?

Could you plz double check on it?

thx
