QACM: QoS-Aware xApp Conflict Mitigation in Open RAN

IEEE Transactions on Green Communications and Networking
The advent of Open Radio Access Network (RAN) has revolutionized the field of RAN by introducing elements of native support of intelligence and openness into the next generation of mobile network infrastructure. Open RAN paves the way for standardized interfaces and enables the integration of network applications from diverse vendors, thereby enhancing

Integrating Zero Trust Architecture in O-RAN: A Comprehensive Survey and Analysis

IEEE Open Journal of the Communications Society
Open Radio Access Network (O-RAN) is a new approach to mobile networks that disaggregates the network architecture into multi-vendor interoperable physical and software-defined network components connected through standardized open interfaces.

User Classification and Traffic Steering in O-RAN

IEEE Open Journal of the Communications Society
The O-RAN architectural framework enables the application of AI/ML techniques for traffic steering and load balancing. Indeed, an effective steering technique is crucial to avoiding ping-pong and radio link failure.

Towards Quantum-Safe O-RAN: Experimental Evaluation of ML-KEM-Based IPsec on the E2 Interface

Future Internet
As Open Radio Access Network (O-RAN) deployments expand and adversaries adopt “store-now, decrypt-later” strategies, operators need empirical data on the cost of migrating critical control interfaces to post-quantum cryptography (PQC).

Mobility-aware service migration and two-timescale task offloading for distributed edge computing in open RAN

Scientific Reports
This paper proposes a mobility-aware two-timescale orchestration framework for distributed edge computing in Open Radio Access Networks, where user mobility, handover events, service migration, task offloading, and radio–compute allocation are jointly ...

ISAC-Assisted DRL for Dynamic MAC Scheduler Reconfiguration in O-RAN

IEEE Open Journal of the Communications Society
This paper introduces reconfiguration mechanisms for a 5th Generation (5G) Medium Access Control (MAC) scheduler, which uses Deep Reinforcement Learning (DRL) and is deployed as an xApp within the RAN Intelligent Controller (RIC) framework. The objective

xDevSM: Streamlining xApp Development With a Flexible Framework for O-RAN E2 Service Models [PDF]

RAN Intelligent Controllers (RICs) are programmable platforms that enable data-driven closed-loop control in the O-RAN architecture. They collect telemetry and data from the RAN, process it in custom applications, and enforce control or new ...

Toward a Multi-Layer Defence Framework for Securing Near-Real-Time Operations in Open RAN

IEEE Open Journal of the Communications Society
Securing the near-real-time (near-RT) control operations in Open Radio Access Networks (Open RAN) is increasingly critical, yet remains insufficiently addressed, as new runtime threats target the control loop while the system is operational.
