Hello Experts.

Is there any way to calculate the VoIP traffic like Whatsapp in each site, each cell?

Any counters ?

Vendor is Huawei.

In LTE Voice can be mapped over QCI1 and QCI7.

And DL traffic can be measured with counter DLTrafficVolume_QCI _1 and DLTrafficVolume_QCI _7 respectively.

I am afraid services based (WhatsApp, Youtube) traffic segregation is not possible in RAN performance, but can be done throughput probe solution.

Might be possible if WhatsApp is mapped to a specific QCI by Core and users using it shift to that QCI as a result.

For one operator I worked at previously, shifted Open Signal Users to QCI-6, but this has to be done through Core.

Thank you all for your insightful reply

And please how can we measure the voice quality of this kind of voice service?

You have counters for QCI1 quality in Huawei.

The QCI1 is configured for VoLTE service.

But I am talking about OTT voice service like Whatsapp.

7

Yes, for VoLTE I mean.

But how do you expect RAN to distinguish specific WA traffic? Only if it is mapped on a specific single QCI like 7

And no other traffic is carried over QCI7, only whatsapp

8

In this case I guess we have to define this type of service over a QCI7?

9

Yes, exactly.

And even after you do this in Huawei those are all counters for QCI7.

Nothing related to Quality.

10

Generally, QCI7 is used for Voice, video, and interactive non GBR services.

If you are using only one QCI for all non-GBR services then it might be possible configuration of Specific service for QCI7 will work.

Please check the QCI wise traffic as first step.

11

You can performe Drive Test using TEMS for example.
I am sure it has some KPIs to show YouTube, WhatsApp quality of service

12

Yes, it’s possible! Telecom operators use Deep Packet Inspection (DPI) tools and sophisticated network monitoring systems at each cell site and throughout their network. These allow them to identify WhatsApp’s VoIP traffic, measure its bandwidth, number of calls, and even assess call quality metrics like jitter and packet loss, even though the calls are encrypted.

13

If you have an OCS this can be easily achiveable.you just have alloacate seperate Rating group in OCS and PCRF for whatsapp.OCS will generate what ever the report you want for that Rating group.Cell wise data, user wise, you name it.

14

You can not measure this at RAN side, it is OTT .

But I think using another application like SmartCare can map such traffic & calculate it
