Introduction to Conflict Mitigation in O-RAN: Categorization of Conflicts

This blog post introduces the topic of conflict mitigation. To mitigate conflicts properly, the advanced detection and classification conflict approach is needed. At first, we discuss possible scenarios of conflicts, between decisions from Apps located at different or the same RIC. We then zoom into the Near-RT RIC and analyze types of conflicts between xApps. Finally, we discuss the impact of conflicts on the O-RAN network.

What Time Is It? Synchronization in Telecom Networks

Time synchronization has recently emerged as an important requirement in telecom networks for several reasons. It ensures that devices and systems across networks operate cohesively, which is crucial for data integrity and maintaining the quality of the service. Additionally, accurate timekeeping is vital for security protocols, as many encryption methods rely on precise timestamps.

Energy Efficiency in Open RAN with Smart RF Channel Tuning

Recently, energy efficiency has been pointed out as one of the key requirements within mobile networks. The development of intelligent algorithms providing RAN with EE features is possible when having access to the KPIs, and proper control actions, e.g., cell on/off switching, or RF channel reconfiguration. These features together with a ML framework are available in the O-RAN architecture. This post provides an overview of the EE framework according to the use cases specified by the O-RAN ALLIANCE. It is followed by the implementation of the ES-rApp as per Rimedo Labs' implementation.

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.

xApp Implementation: O-RAN Traffic Steering Use Case

In this post, we focus on the implementation of a simple xApp tailored for the traffic steering use case. The goal of this xApp is to support the network providers to reassign the traffic from one gNB to the other in order to meet some predefined criteria. We will see some results of the great opportunity offered by Open RAN that the operator can easily install, modify or remove the xApp when needed.
