3GPP Rel-19: Maturing 5G-Advanced 

3GPP Release-19 is the second release of the 5G-Advanced standard. Early workshops on this release were held in June 2023 discussing hundreds of submissions. The original assumption was that 3GPP Rel-19 would primarily focus on investing in the 5G-Advanced commercial deployments to further improve performance and address critical needs. In this post, we’re elaborating on the contents of the selected WIs and SIs to be incorporated within 3GPP Rel-19 as of December 2023.

Traffic Management for V2X use cases in O-RAN

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”

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.

Energy Saving-rApp control over Traffic Steering-xApp

Energy consumption is a critical aspect of any service in these modern times. In telecommunications, a flexible approach to network planning, control, and management is extremely beneficial in this aspect. The concept of O-RAN enables the creation of algorithms that allow energy saving in a manner independent of the equipment or RAN software solution used. In this blog post, we present an innovative approach to energy saving using the RIC, which is based on the direct cooperation of Traffic Steering xApp and Energy Saving rApp.

O-RAN Deployment Scenarios

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.

Rimedo Labs Integrated the TS xApp with VMware Distributed RIC and Won the rAppathon

Rimedo Labs integrated a Traffic Steering xApp into the VMware dRIC. Rimedo’s Policy-Controlled Traffic Steering xApp running on the VMware Distributed RIC incorporates both service and mobility load balancing to avoid congestion, improve user experience and make the network more energy efficient. Rimedo’s xApp was the winner of the inaugural rAppathon RIC application developer competition hosted by VMware and Intel at MWC 2023.
