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.

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

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).

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.
