Huawei NodeB UE Latency & Jitter

Dear Friends,

I need to know how I can troubleshoot and enhance the
latency & Jitter in my network for UE end, I have a Huawei 3G network with RNC6900 and
DSB3900. the latency in my network as tested from "speed test" is high and not
stable at all, the issue is mostly obvious in the online gaming and the customer
perception is very bad.

my question is:

1- how much backhauling
can affect the latency/Jitter and how to check it?
2- can radio parameters affect
the latency/Jitter stability and how to check it?
3- does core parameters affects
the latency/Jitter and stability of network and how to check it?
4- what are the
counters or the method to check the latency/Jitter of 3G IP network from NodeB
side?
5- how can I enhance UE latency/Jitter and make it stable?

Regards,

You can enable Twamp standard protocol or IPPM (huawei) feature. It provides information about delay/delay variation.

BR,

Ivan

Many thanks Evan for the reply, I have the IPPM already activated but is there any supporting document in order to make the analysis per NodeB ?
