    • Overview of Ric Standardization at O-Ran Alliance
    • Implementation Scenario For Intelligent Ran
    • Summary
    • Conclusion

    The mobile network of the fifth-generation mobile communications system (5G) is expected to provide services that can satisfy diverse requirements and conditions such as high speeds and large capacity, low latency, and massive connectivity. To meet these advanced service requirements, mobile network operators have been working continuously to enhan...

    2.1 RIC Architecture

    In RAN architecture at the O-RAN ALLIANCE, a RAN Intelligent Controller (RIC) is defined as a logical node for performing base station parameter design and settings and automating and optimizing operations with the aim of achieving intelligent network operations using AI/ML. As shown in Figure 1, RIC is defined as Non-Real Time (Non-RT) RIC and Near-Real Time (Near-RT) RIC. Among these, Non-RT RIC is situated within the Service Management and Orchestration (SMO) block that performs RAN monito...

    2-3 rApp/xApp

    Control algorithms running on Non-RT RIC and Near-RT RIC are implemented by rApp and xApp, respectively, as described above, and are separated from the Non-RT RIC framework and Near-RT RIC framework by the R1 interface and Near-RT RIC APIs, respectively. This scheme enables a mobile network operator to freely select applications. In other words, it is possible to adopt not only an rApp from a vendor that provides a Non-RT RIC framework but also an rApp provided by a third party. An operator c...

    2.4 Application of ML

    Recent progress in cloud technology has made it easy to accumulate large amounts of data, and as a result, the application of ML to a variety of fields is attracting attention. At the O-RAN ALLIANCE that aims to achieve intelligent RAN, there are expectations that network performance will improve by applying ML to the RAN field, so architecture for making that possible is being prepared. The application of ML requires training and inference processes. In the training process, network performa...

    3.1 Intelligent RAN Roadmap

    On implementing intelligent RAN by RIC, the functions and control interfaces that will be needed and the data collection items needed for optimization analysis will differ depending on the use cases adopted, and the interfaces and functions needed in RAN equipment (next generation NodeB (gNB)*39) will differ as well. The formulation of an implementation plan that takes the above into consideration is therefore important. It is also necessary to draw up a plan for enhancing intelligent RAN in...

    3.2 Examples of Use Cases in Each Phase

    The following introduces (1) optimization of HO control parameters as a use case for the initial phase and (2) traffic steering as a use case for the following phase. 1. (1) Optimization of HO control parameters Executing a HO between a base station and UE either too early or too late will cause a HO failure and the UE to be temporarily disconnected from the network. To prevent such a failure from occurring, Non-RT RIC can adjust threshold values, timing, etc. used in HO control by analyzing...

    4.1 Future Issues

    The following problems related to multi-vendor operation are taken up as future issues. Activities are progressing in O-RAN ALLIANCE WG5 with the aim of achieving multi-vendor interoperability in RAN equipment interfaces, but interoperability is also needed for RIC interfaces (R1 interface, A1 interface, E2 interface, Near-RT RIC APIs, and external interfaces to outside services and applications). Specifications for these interfaces are currently being drafted in WG2 and WG3, but clarificatio...

    4.2 Future Use Cases

    Looking to the future, RAN parameter optimization using data outside the RAN domain can also be considered. As one example, we can consider mobility optimization on an expressway. In this case, RIC optimizes base station parameters according to the speed of user-terminal movement and user-terminal density using not only base station data in the vicinity of the expressway but also real-time congestion information or congestion prediction data provided by the expressway management company. We c...

    This article described RIC now being standardized at the O-RAN ALLIANCE, a roadmap and various use cases as a scenario for implementing intelligent RAN, and upcoming issues and future use cases. Going forward, NTT DOCOMO plans to continue making contributions to the drafting of specifications for intelligent RAN at the O-RAN ALLIANCE. It will also ...
