Dear SDR hackers,

We are excited to announce the release of srsRAN 21.10  [1].

This release brings 5G NSA support to srsENB, paving the way for our 5G SA applications coming in 2022. With this, users will now be able to create an E2E 5G NSA network using srsUE, srsENB and srsEPC. Our 5G NSA eNB is LTE Release 15 aligned, with support for NR FDD & TDD configuration and 5G NSA COTS UE support.

21.10 also brings a host of other improvements to srsRAN, including improved interoperability of srsUE in NSA mode, the addition of JSON output for both the UE and eNB metrics, and various other bug fixes and stability improvements.

We have added application notes outlining how to connect a 5G NSA capable UE to srsRAN [2] and how to create an E2E NSA network using srsRAN and ZMQ [3], as well as user manual updates introducing 5G NSA and how it is implemented in srsENB [4].

The full changelog for 21.10 is available on GitHub [5] for those that would like more information on the improvements and changes that come with the new release.

Today will also see the release of CoreScope [6], a test and performance analysis tool for 5G core networks. CoreScope builds on the srsRAN software suite, combining a 5G gNodeB and UE to connect directly to a 5G core and exercise it. This is all done without the need for RF-hardware. 
CoreScope does this by behaving like a UE, connecting directly to the AMF and UPF via the N2 and N3 interfaces to perform a complete network attach and bearer activation procedure.

Once connected, users will be able to use the integrated WebUI to view live metric reports, and explore the complete functionality of CoreScope. A Python API is also available, allowing users to spawn UEs and gNBs while CoreScope is running and to create bespoke test cases.
Further details can be found on the dedicated CoreScope wiki [7].

Happy hacking and enjoy the release.

Dear Atanas,

could try again with the 21.10 release and report back if the issue 
still exists. Please run the eNB with log level info.

Thanks
Andre

Dear Andre,

Thank you very much for the suggestion. But we were not able to find the
packages for that version.
However, we have fixed the problem. It seems the IP of 127.0.0.1 was
already by our MSC (which we use for SMS over SGs). So we have changed the
IP of the eNB to 127.0.1.1 and everything is working fine now.

Have a nice weekend all! And thank you for the suggestions.

Best regards,
Atanas
