how to increase node b capacity?

[jimjim]

Hello there,

What do you use for transport, is it IP or ATM?

DL you say... I'm actually not sure how iub resurces are distributed or better say dedicated between dl and ul.
As I remember, at least there is only one kpi for iub !?
I would say it's worth trying out.
You will see the results after 15/30 min then you can roll back anyway.

Keep us updated ;-)

For IUB exists counters for UL&DL:

UL/DL cong:

VS.RRC.Rej.ULIUBBandCong
VS.RAB.FailEstab.CS.ULIUBBand.Cong
VS.RAB.FailEstab.PS.ULIUBBand.Cong
VS.RRC.Rej.ULIUBBandCong
VS.RAB.FailEstab.CS.ULIUBBand.Cong
VS.RAB.FailEstab.PS.ULIUBBand.Cong

Iub bandwidth utility ratio

For ATM DL: VS.AAL2PATH.PVCLAYER.TXBYTES, VS.QAAL2.AllocedFwd.AAL2BitRate, VS.QAAL2.AllocedMaxFwd.AAL2BitRate.Value

For ATM UL: VS.AAL2PATH.PVCLAYER.RXBYTES, VS.QAAL2.AllocedBwd.AAL2BitRate, VS.QAAL2.AllocedMaxBwd.AAL2BitRate.Value

For IP DL: VS.IPPATH.IPLAYER.TXBYTES, OS.ANI.IP.AllocedFwd

For IP UL: VS.IPPATH.IPLAYER.RXBYTES, OS.ANI.IP.AllocedBwd

And what i've found for IUB bandwith congestion:


Generally, the allocated bandwidth should be approximate to the actual traffic. Then, the configuration of the activation factor is appropriate. If there is a great difference between them, you can optimize the configuration of the activation factor appropriately.
If IUB congestion causes RRC access failure, the reason is usually that traffic increases or the activation factor is not configured reasonably. Therefore, you need to increase the Iub bandwidth or optimize the configuration of the activation factor.

It means, that possible to play with activation factor. We use default value, but maybe someone has exp with it and can share

I suggest you to find documentation here, on this WEB:
- RAN10 KPI Troubleshooting Guide-20090306-A-V1.0
- WCDMA Handover Troubleshooting Case

it will help you

Thank a lot my freind
a first document is very good but for second
i can not found it . i found W-Handover and Call Drop Problem Optimization Guide but I don't know if it is a same .

Thank
