IP PM Detection to Check IP Path Performance on the Iub Interface


This function detects delay, variation (that is, jitter), and packet loss rate of the IP path on the Iub interface.


If packet loss occurs, IP PM activated on the RNC detects the downlink packet loss, and IP PM activated on the NodeB detects the uplink packet loss.

Procedure:

Determine the IP path to be detected.

Run ACT IPPM on the RNC or ADD IPPMSESSION on the NodeB.

Results:

Check for the following alarms on the RNC or NodeB:

1.  NodeB ALM-25900 IP PM Activation Failure

2.  RNC ALM-21341 IP PM Activation Failure


If one alarm is generated, the IP PM function is unavailable.



If no alarm is generated, check the performance counters to obtain the TX rate, packet loss rate, jitter, and delay of the IP path.



for Packet loss rate:

VS.IPPM.Forword.DropMeans

VS.IPPM.Forword.Peak.DropRates


for Jitter:

VS.IPPM.Forward.JitterStandardDeviation

VS.IPPM.Back.JitterStandardDeviation


Delay:

VS.IPPM.Rtt.Means IPPM

VS.IPPM.MaxRttDelay IPPM

Hello All,

Is the IPPM counters combatable to be activated on DBS3800 & BTS3812 as well?

Regrads,
