OSC near-RT RIC works with srsRAN

[Summer-GY]

I've noticed that FlexRIC and srsRAN have many issues that prevent them from operating normally. I would like to ask if the OSC near-real time RIC can be used normally with the RAN Control xApp to perform some actions, such as Radio Resource Allocation, to control the RAN?

I am working with the OSC I-Release and srsRAN. The connection process (E2SetupRequest and E2SetupResponse) is working. I tried to deploy the kpimon-go xApp for basic metric reporting, but the app crashes when trying to send the subscription request.

Hi there.

Where can I find the subscription request message? And how are you deploying your xApp?

dear @P4sca1 , I've experienced the exact same issue. Were you able to resolve it?

[Summer-GY]

On the tutorial, it says Control Service Style 2 is supported. So, which nearRT-RIC and xApp can we install now to achieve this control? Do you have any suggestions or comments?

[P4sca1]

I only looked into monitoring xApps yet.

Hi @Summer-GY and @P4sca1 ,

We have just released a repository that allows running ORAN-SC-RIC as a multi-container Docker application with a single docker command. You can access the repository at: https://github.com/srsran/oran-sc-ric

Moreover, the repository includes two Python-based xApps examples designed to facilitate the requesting and monitoring of E2 metrics from the gNB. These examples cover all reporting styles (1-5) of the e2sm-kpm module, which has been updated to version 3.

To get started quickly, refer to the Quick Start section in the readme file.
Please note that until the next code release, you'll need to utilize the test branch from the srsRAN_Project repository.

We are currently working on an example xApp using e2sm_rc module.

Many thanks for the updates, I will have a look at the new repository at some point.

Thank you for the effort. The ability to deploy the ORAN RIC with a single Docker compose file instead of a Kubernetes cluster, makes experimenting with it a lot easier.
I was able to successfully integrate the repository into my test network. The Python xApp is running successfully.

Hi @pgawlowicz

The ORAN-SC-RIC repository and xApps examples are great! They've made experimenting much easier.

Regarding the e2sm_rc module xApp example you mentioned - do you have a rough timeline for when it might be available? We're quite interested.

Thanks for all the excellent work!
