Traffic Management for V2X use cases in O-RAN

2023-12-02
In this blog post, we show how the utilization of both Traffic Management rApp and Traffic Steering xApp could help in V2X scenarios. We also emphasize the use of enrichment information, made available through O-RAN, that suits specifically to vehicular services, such as car platoon geolocation or emergency situation notifications. The flexibility offered by the O-RAN architecture allows for optimized resource management through policy control in companion with EI when dynamic changes occur on the road. This is analyzed within the context of specific O-RAN use cases related to V2X.

„The O-RAN Whitepaper 2023 – Security in O-RAN”

2023-11-03
Recently, security has been pointed out as one of the critical aspects moving forward within the O-RAN domain. Expanded threat surface, as well as specific security challenges and opportunities, have been identified. This whitepaper provides an overview of security topics in O-RAN, specifically in 5G/6G mobile radio networks. We also consider artificial intelligence embedded in the network edge as a great tool to support security. We present some xApps applied to detect and mitigate example attacks. Conclusions and a discussion on the directions of future developments follow this.

O-RAN Deployment Scenarios

2023-07-02
Deployment scenarios that the O-RAN ALLIANCE specifies, define how to compose the elements of O-RAN architecture in the actual deployment in the network within the cloud and physical locations. One of the key aspects is that the general split from the deployment perspective is the open Fronthaul, with the the separation between O-Cloud deployed entities, and the PNF, for O-RU component. In this blog post, we are providing an overview of different scenarios and deployment options as presented in the O-RAN resources.

O-RAN Security and Security Offered by O-RAN

2023-05-06
This year, the most crucial topics for further development in O-RAN are security and energy efficiency. In this blog post, we investigate how different players of the O-RAN ecosystem look at the security topic. Those include O-RAN ALLIANCE, the telecommunication business (including operators and providers), governmental bodies, IEEE, and academic researchers.

„The O-RAN Whitepaper 2023 – Energy Efficiency in O-RAN”

2023-04-03
Recently, within the RAN domain, energy efficiency has been pointed out as one of the key requirements moving forward. It has been defined as end-to-end involving all domains within the O-RAN system. The overall objective for O-RAN is to gradually become more energy efficient than the regular RAN. This should not be at a cost of the key O-RAN concepts including cloudification and disaggregation. This whitepaper provides an overview of the energy efficiency topic in 5G mobile networks and how it fits into the O-RAN area. This is followed up by example algorithms utilizing ML schemes and their realization in the form of rApps based on O-RAN use cases.

O-RAN Network Energy Saving: RF Channel Switching

2023-03-01
In this blog post, we provide the description of an algorithm that can be realized as an rApp in the O-RAN architecture aimed at improving the network’s EE through intelligent RF channels on/off switching. First, we provide a general framework for long-timescale EE optimization which can be done in Non-RT RIC. We then propose the implementation of the RF Channel Switching algorithm within the O-RAN framework. Finally, we discuss some opportunities and challenges.
