The gNB will stop the periodical logging of UEs in MAC Info level after
a configurable number of UEs have been printed, by default 8.
Set it to 17 in some CI tests to ensure we still get all UEs for the
time being, as the CI might depend on this.
CI: Upgrade Aerial setup to 25-2.1
The purpose of this MR is to upgrade the cuBB image in the Aerial setup to
release 25-2.1 and update the doc/Aerial_FAPI_Split_Tutorial.md accordingly.
CI: Upgrade HO setup to use an attenuator
The goal of this MR is to upgrade HO CI setup to include a digital attenuator
that will allow us to trigger handover by attenuating the signals on the DUs.

- Trigger handover
- IdleSleep 2s
- Ping ext-dn from NR-UE
- Verify UE(1) connected to DU-PCI1
Validate absence of heap-use-after-free ASAN error found in !3600.
Closes#940
- On PUSH events, if image build stages succeed, trigger DockerHub push stage
- Build the images, then trigger the Push to DockerHub stage
- Publish Jetson (ARM64/v8) and AMD64 images under the same tag on DockerHub
The next commit introduces an "UL-heavy" configuration to be tested with
Aerial. To avoid waiting for the CN, start&stop it once at the beginning
of the CI run.
Reduce throughput requirement, as this fails once two DUs are connected
to a UE, which creates more load on the machine and frequently fails
with low throughput.
CI: Enable Physim threshold check for tests on Caracal and GH
This MR adds support for configurable timing threshold files in PhySim
tests.
- Introduces a new CMake cache variable PHYSIM_CHECK_FILES to specify
one or more timing threshold files (semicolon-separated).
- Enables optional enforcement of timing thresholds check in PhySim
tests without changing existing test definitions.
- Defines timing thresholds for LDPC encoding/decoding in nr_ulsim,
nr_dlsim and ldpctest on Caracal and GH machines.
Also, don't use "set -x" debugging for oc login command:
ci-scripts/cls_cmd.py:242 sets BASH_XTRACEFD=1, which makes that all
"set -x" output is in stdout, leading to a redirect to the file into
which we redirect. This would lead to the following error with
unsuccessfull oc login:
error: You are not a member of project "****-core-for-ci-ran".
Error from server (Forbidden): imagestreams.image.openshift.io "oai-physim"
is forbidden: User "system:anonymous" cannot get resource "imagestreams" in
API group "image.openshift.io" in the namespace "****-ran"
This fixes basically two problems. First, remove "set -e", which leads
to the script exiting on error. For instance, there was the sleep which
should account for the time of the pod being in "ContainerCreating", but
might not be enough. In that case, the script would exit, leaving the
pod deployed.
Second, a fixed time is not good, as it can be too short and unduly
prolong waiting time. Replace with a loop.
Add OAIUE longrun pipeline
Add a new XML file for OAIUE longrun.
- Test description:
* 40 MHz BW, n78
* gNB with USRP N310, UE with USRP N310
* CN deployed on OC
- Test duration: 1 hour
- Test scenario: 3x DL 10 min test (20 Mbps) + 3x UL 10 min test (5
Mbps)
pods deployed through helm occasionally take more time, leading to
errors such as
Error from server (BadRequest): container "physim" in pod "oai-physims-4g-sczvl" is waiting to start: ContainerCreating
Give a bit more time before checking the logs. We cannot wait too much,
as the container will just end on FINISHED in running state, so the logs
will always be there.
Previously, the script attempted to directly merge ${merge}, which could f
ail if the branch was not already available locally. This update explicitly
fetches the branch from origin and then merges FETCH_HEAD with --ff, ensuring
the merge works even when the branch is missing locally.
- Remove extensive traffic testing before HO (iperf tests 030001, 030002)
- Do 1 ping test after attachment
- Reduce ping packet count from 100 to 50 packets for remaining connectivity test
Time savings: ~2-3 minutes by removing traffic validation overhead
`def` creates a variable local to the script object, not automatically visible inside helper functions.
This fixes the following exception in Jenkins:
Found unhandled groovy.lang.MissingPropertyException exception:
No such property: OAI_Registry for class: groovy.lang.Binding
Lower the RX gain used by the Amarisoft UE in CI tests to prevent DL signal
saturation. This resolves an issue with low DL throughput observed in CI.
RX/TX signal levels on the Amarisoft UE can be checked with "t spl" command
in lteue; MAX values should not approach 0.
Extend t300 in multi_ue rfsim testcase
Extend t300 to 1000 to increase the time the gNB has to handle MSG3. Hopefully
this prevents the UEs from timing out after MSG3. Add UE id to timer timeout
LOGs so the UE behavior can be traced through the stack.
Code cleanup (SRS, config files and more)
- Remove deprecated elements from some configuration files (also closes#997)
- Improve SRS code with a better separation between common code and gNB/UE code
- Other minor compilation improvements
N2 handover
This MR introduces full support for N2 handover, covering handover
decision, preparation, execution, and notification between source and
target NG-RAN nodes.
Key features:
1. Handover Decision & Preparation:
- Implement N2 handover decision based on UE measurement reports.
- Generate the Handover Preparation Information message, including
RRCReconfiguration.
- Send Handover Required message from the source NG-RAN to the AMF.
2. Handover Execution:
- Decode and handle the Handover Request on the target NG-RAN.
- Process the Handover Command on the source gNB, triggering
RRCReconfiguration.
- Initiate Handover Notify after successful completion.
3 NGAP & RRC Enhancements:
- Implement NGAP encoding/decoding functions for Handover Required,
Handover Request, Handover Command, Handover Failure, and Handover
Notify (3GPP TS 38.413).
- Adds NG-RAN Status Transfer support (UL/DL) for PDCP COUNT
preservation during mobility:
- support for NGAP Uplink and Downlink RAN Status Transfer messages
(TS 38.413 §9.2.3.13-14) to enable proper PDCP COUNT value
transfer during handover or recovery: NGAP encoding/decoding for
RAN Status Transfer, PDCP helpers to extract and apply COUNT (HFN
+ SN) per DRB. This aligns with TS 38.300 §9.2.3.2.1 and TS 23.502
§4.9.1.3.3, ensuring PDCP status preservation in AM.
4. Testing:
- Introduce a Telnet command to manually trigger N2 handover using UE
ID and neighbor PCI.
- Add configuration file for testing N2 handover with a target gNB.
