Welcome to the E release page for the O-RAN Software community.
The E release is currently under development completed and its source code is maintained within teh the master branch of each repo. Once released further instructions related to separate maintenance branches and The release image lists will be available here,and source code can be found here for each projects.

Near-Real-time RIC X-APPs (RICAPP) |
---|
Primary Goals: Expand the community working on open source xApps for O-RAN SC. Enhance the set of open source xApps in support of the R-SAC use cases (traffic steering, network slicing) as well new use cases. Update and enhance existing xApps to take advantage of the new features in xApp SDK (implemented by the xApp frameworks in C++, go, and python). |

Near-Real-time RAN Intelligent Controller Platform (E2 Interface) (RICPLT)
Mission: E2 updates with first E2APv1.1 support and improvements in E2 subscription handling. A1 reimplementation
Original primary goals: Update to E2APv1.1 (E2 Node configuration transfer in E2 Setup and E2 Configuration Update (RIC-638, even if likely changing again in E2APv2.0) and E2SM OID support in internal E2SM function query interfaces (RIC-640)) // RIC-809 Subscription manager to delete subscriptions in case of E2 disconnect (incl. Xapp changes) // RIC-793 Prevent A1 Job ID conflicts from multiple RICs using the same A1 producer (SMO) // RIC-647 Reimplement A1 mediator in golang to avoid A1 being the only python container in RIC platform // RIC-709 E2 stats exposing individual counters instead of groups // RIC-714 support for DMS REST interface in addition to DMS CLI // RIC-113 DB: SDL CLI for debugging and testing // RIC-110 FindKeys/GetAllKeys SDL API to support glob-style patterns // 34 Epics planned: link and 30 items as stretch goals: link

E release source code, container images and deployment instructions
We again plan to cut a branch from the master branch once the E release is released and goes into maintenance. Also we plan to provide an ready-made container image list.Non-Real-time RIC (A1 Interface) (NONRTRIC)
- The primary goal of Non-RT RIC is to support intelligent RAN optimization by providing policy-based guidance, ML model management and enrichment information to the near-RT RIC function so that the RAN can optimize, e.g., RRM under certain conditions.
- It can also perform intelligent radio resource management function in non-real-time interval (i.e., greater than 1 second).
- Non-RT RIC can use data analytics and AI/ML training/inference to determine the RAN optimization actions for which it can leverage SMO services such as data collection and provisioning services of the O-RAN nodes.
- Non-RT-RIC will define and coordinate rApps (Non-RT-RIC applications) to perform Non-RT-RIC tasks.
- Non-RT-RIC will also host the new R1 interface (between rApps and SMO/NONRTRIC services)

E release source code, container images and deployment instructions Each repository has a branch named "e-release" that can be accessed using git. For example, the source code for the AD xApp can be retrieved using "git clone --branch e-release "https://gerrit.o-ran-sc.org/r/ric-app/ad". The other xApps in the E release can be found at ric-app/qp, ric-app/ts, ric-app/lp, ric-app/hw, ric-app/hw-go, ric-app/hw-python, ric-app/mc, ric-app/bouncer, ric-app/rc, and scp/ric-app/kpimon. Note that the other ric-app repos are obsolete. Note that this branch is in maintenance and all new development is done in branch "master". In order to deploy the E release xApps, you can re-use the pre-created container images as defined here and the instructions on testing the xApps can be found here. |

For the E release of the near-RT RIC we did only limited integration testing: only the use cases: deploy RIC, deploy xApp and make E2 connection were tested. Filled in end-of-release checklist : Release criteria checklist - Release E |

Status 2021-12-08: From the 29 epics planned (link) we implemented 16 (link). 13 items have been moved out of the E release, e.g, because of implementation delays (link). Incomplete items: 0 (link). |
E release source code, container images and deployment instructions Each repository has a branch named "e-release" that can be accessed using git: "git clone --branch e-release "https://gerrit.o-ran-sc.org/r/ric-plt/e2". Make sure to replace the URL with correct repositories. Note that this branch is in maintenance and all new development is done in branch "master". The complete list of repositories belonging to the RIC platform is defined here: Scope of the near-RT RIC platform and its components (summary). In order to deploy the E release of the near-RT RIC platform you can re-use the pre-created container images as defined here. The same instructions as always apply, i.e., follow the general latest instructions: https://docs.o-ran-sc.org/projects/o-ran-sc-ric-plt-ric-dep/en/latest/ → Installing Near Realtime RIC in RIC Cluster, but make sure to use "git clone --branch e-release ..." instead of "git clone ..." when cloning it/dep and ric-plt/ric-dep. If you clone it/dep and use the "ric-dep" as submodule, make sure to run: "cd ric-dep; git checkout e-release" after "git submodule update --init --recursive --force" |

Service Management and Orchestration (SMO) | ||||||||
---|---|---|---|---|---|---|---|---|
Primary Goals: The primary goal of the SMO project is to integrate different software artifacts of existing open-source projects creating a fully functional open-source Service Management and Orchestration (SMO). | ||||||||
E Feature Scope: In E-release, SMO will be extended to support network slicing. In particular, RSAC has come up with closed loop automation use case for network slicing which involves the SMO collecting PM counters related to network slicing, and based on them breaching some thresholds will cause a change in the configuration of the network slice. That means the SMO has to have support for PM counters related to network slicing, and an ability to reconfigure the O-DU for the network slice. Separately, AT&T has asked for a disaggregated VES solution that separates the collection of VES events from how it is presented to any application that wants to view them:
