[Announcement] UERANSIM v3.0.1 Released

[aligungr]

Hello everyone,

I want to inform the community briefly about the new release. With the version v3.0.1 following changes are applied:

General:

• UERANSIM code base completely migrated from Java to C++. And therefore JDK and JOME_HOME setting are no longer required. You can distribute the UERANSIM binaries as standalone applications.
• We achieved some extreme performance improvements in the new version. For instance UE authentication procedure is about 200x faster than previous versions.

Execution:

• UE and gNB are completely separated. Our UE and gNB are no longer integrated, but they work separately. In this way you can deploy UE and gNB instances in different environments.
• UERANSIM now provides 2 seperate programs called nr-gnb and nr-ue. ~At the same time, nr-agent and nr-cli have been removed. A different CLI feature will be also added in the future.~ (PS: CLI is now available with 3.1.0)

5G Radio:

• UERANSIM is no longer a simulator, but it is a UE and gNB implementation, since we're also working on 5G radio interface.
• Currently we completely implemented Radio Link Control (RLC) protocol and partially implemented Radio Resource Control (RRC). Other layers of the NR stack is still in progress. Therefore radio features are not testable over SDRs yet.

Web UI:

• Some of contributors have developed a user interface for UERANSIM. We'll release the GUI after completing some official procedures. I think it'll take some time.

Others:

• Profile based configuration system is removed. Instead, UERANSIM expects the config files as a command line input. Also some predefined config files are present in the repository for open5gs and free5gc for easy access.
• Logging format and log messages have been changed and are more user friendly. Also we removed logging to file.

Lastly, some new bugs might be injected with the new version. Please feel free to report any issues you found. And as always, public contributions are welcomed and highly encouraged.

Thank you for using and supporting UERANSIM.

Hi @aligungr

It's excellent!

I used it immediately and updated my sample configuration. Thank you very much!

By the way, with the separation of UE and gNB, and the support for Xn handover by Open5GS at the beginning of this year, could you have any plans of the simulation of Xn handover by two gNBs and Open5GS?

I am very interested in the simulation of Xn handover in private 5G. I haven't got the real gNB yet. (but I have a plan to use the real eNBs soon.)

@s5uishida

Thanks for the update, I appreciate your works.

... could you have any plans of the simulation of Xn handover by two gNBs and Open5GS ...

Yes we have a plan for implementing location report and handover procedures. After the implementation, we provide some functionalities for simulating the handover. However I cannot give an exact date for this feature. But it is in short-term roadmap.

By the way, I plan to use GitHub dashboard in the future more effectively, you can follow the development status as a summary at Development Board

@aligungr Could you give a rough timeline about when the new features like handover, location report, etc. would be implemented ? It would really help me in scheduling my tasks. Thanks so much.
