Vonr setup

[b3c3ll]

Hi @herlesupreeth

Thanks for the update. I want to setup Vonr setup but i'm not sure about the path!
Following the guides wont go into pyhss container!

For 5G deployment only

docker compose -f sa-vonr-deploy.yaml build

5G Core Network

docker compose -f sa-vonr-deploy.yaml up

i've tried both main repo and open5gs_hss_cx
but none of them wont go into osmohlr or pyhss ip address!
docker exec -it osmohlr /bin/bash

Would you please guide me through the VoNR setup?
Thanks
Best regards

Also the part related to

Provisioning of SIM information in pyHSS is as follows:
Goto http://<DOCKER_HOST_IP>:8080/docs/

is not working!
Would you please correct me?
Thanks @herlesupreeth

The thing is
master branch has pyhss folder but the cx branch does not!
and the "sa-vonr-deploy.yaml" file do not contain "osmohlr" related configs!!

So it wont be possible to use Cx branch for SA-Vonr deployments.

[herlesupreeth]

omsohlr and osmomsc is used only in 4G deployment in order to send SMS over SGs interface. But whereas in the case of 5G there is no SGs interface hence its not there is sa-vonr-deploy.yaml

[herlesupreeth]

Master branch uses pyhas for IMS where as cx branch uses open5gs HSS for EPC + IMS

[b3c3ll]

So there is no way to have both SMS and Vonr at the same time?
Or the pyhss handles the SMS
Thanks

Even after setting up pyhss configurations, The Ue is not registering on the VoLTE/Vonr!
Would you please check the traces?

pyHSS is an HSS and does not handle SMS. In VoNR setup there is SMSC based on kamailio and it takes care of SMS over IMS

From this pcap I see that UE is not attempting to create a PDU session for IMS APN, which suggests that VoNR may not be activated on the UE

@herlesupreeth
Thanks for the Reply

What do i need to do in order to obliged UE to Create PDU session for IMS APN?
I have two UEs, One is Samsung A51 and the Other is Oppo reno 4 pro!
Both connects to the 5G network but none of the accepts VoNR or Volte calls.

For Oppo reno, you could try the setup mentioned here https://github.com/herlesupreeth/CoIMS_Wiki to force activate VoNR. For Samsung A51 unfortunately I dont have any method

Now I see phone attempting to connect to IMS APN but no SIP REGISTER is sent. So ensure that VoLTE is enable under phone's mobile network settings and restart the phone and attempt connecting again

[b3c3ll]

On the Samsung A51, as soon as i try to call someone, it loses the Whole 5G conncetion and it needs to manually search for the 5G network! but in the Oppo, it only drops the call and wont able to call!

Would you please let me know which filters do i need to use in wireshark for the sake of knowing which UE attempted to Connect to IMS APN?

[b3c3ll]

in case of the CoIMS ... I've used OYSIMWrite4.2.5 to program the SIMcard. Can I use CoIMS as i seen that it uses OSMOsim?

Thanks

[herlesupreeth]

s1ap || gtpv2 || pfcp || diameter || gtp || ngap || http2.data.data || http2.headers

This is the display filters I use in wireshark but the in order to know which UE connected to IMS you need to take a look at the NGAP packet PDU session Establishment Request. Inside that you should have DNN defined as either internet or ims

in case of the CoIMS ... I've used OYSIMWrite4.2.5 to program the SIMcard. Can I use the following CoIMS as i seen that it uses OSMOsim

Then, I dont think so its possible

On the Samsung A51, as soon as i try to call someone, it loses the Whole 5G conncetion and it needs to manually search for the 5G network! but in the Oppo, it only drops the call and wont able to call!

In case of Samsung A51 that is the case because it may have not attempted to connected to IMS and when you try to place call it may be attempting call over 2G/3G network which is absent hence loses connection

[b3c3ll]

I'm getting Error of

amf | 01/15 10:01:03.670: [gmm] ERROR: [imsi-001010123456795] No Session Context [201] (../src/amf/gmm-handler.c:1111)

While the UE is connected and it has internet access!

[b3c3ll]

restart the phone and attempt connecting agai

After Restart I get this traces:

@herlesupreeth
Any idea on the new trace?
Thanks

[herlesupreeth]

In the latest pcap I see that UE is sending PDU session modification request which is being rejected by 5GC which I am not sure why.

One thing I noticed is that you have set IP type as IPv4v6 in open5gs WebUI for IMS APN and I would recommend to change that to only IPv4 and give it a try

[b3c3ll]

@herlesupreeth
While it was working Ok at that time, I'm not even able to register of netwrok after installing using the latest commit!

What would be the problem?

Thanks
Best regards

[herlesupreeth]

I would check UE SIM programmed details and the ones entered in open5gs WebUI and see if they match.

[b3c3ll]

Goosh! (wrong Op choice in the UI)
Thanks

I'll try to connect Samsung to VoNR(will continue on this thread)

[b3c3ll]

any idea why on the Sam UE VOLTE provisionning is grayed out! and how to enable it?

Thanks

[b3c3ll]

@herlesupreeth
Same UE got powered On but no VOLTE provisioning!

also connected another UE with the VOLTE enbaled!

Is there a way to forcefully enable Volte Provisioning on Sam even with adb?

[herlesupreeth]

I see successful IMS registration in the pcap attached inside 2410-3.zip

[b3c3ll]

@herlesupreeth

I dont see any HD or Volte sign on the Samsung UE while oppo connects and shows!
it is two different UEs!
One got connected easily but the other (samsung) wont even try to connect... as shown in the pic, Volte provisioning is grayed out to off! is there any way to activate it? using adb or ...?
Thanks

[b3c3ll]

New pcap is there:
2410-4 is just samsung UE.
2410-5 is just oppo
2410-6 is oppo + samsung!

I'm not sure why it is not even trying to connect. have you ever find any article to enable this using adb or so?
Thanks

No, there isn't for Samsung sadly
