The QoS rules specified in mongo DB take any effect

[Robin-Rhee]

Hi, Supreeth
As we can see that the mongo DB has been populated with some QoS rules for UDR/PCF to use
I only kept the 5QI=1 for audio and 5QI=2 for video in the ims area
And remove the QoS rules for DNN=internet
I was pretty curious on the real significance of these QoS rules
Because IMS and UE would negotiate the preconditions in SIP protocol
What if removing these QoS rules defined for IMS ?
If they matter, when and where do them take effect ?

And remove the QoS rules for DNN=internet

That was required for VoWiFi clients which establish only one PDN connection (to internet APN) and attempt calling using only that

What if removing these QoS rules defined for IMS ?

I would suggest reading about how Policy enforcing works in Core Network.

Because IMS and UE would negotiate the preconditions in SIP protocol

UE and IMS negotiate the SDP parameters and using that PCSCF (an Application function) can ask PCF/PCRF to provide QoS for an application. So, it is upto the PCF/PCRF's final decision to authorize such QoS for such application traffic. The QoS rules in the WebUI of open5gs are used by PCF/PCRF to authorize or not to authorize the requested QoS by the application function.
