Enabling Experimentation and Evaluation of xApp Direct Conflict Detection and Mitigation in Testbed
… through modular software applications known as xApps. These xApps deliver various network functions such as mobility management, security, and radio resource management by interacting with RAN nodes via the E2 interface. The concurrent execution of multiple xApps within the Near Real-Time RAN …

Detection of Denial of Service Attacks on the Open Radio Access Network Intelligent Controller through the E2 Interface
… capabilities using applications called xApps and rApps. Multiple xApps targeting novel use cases have been developed by the O-RAN Software Community (OSC) and incubated on the Near-Real-Time RIC (Near-RT RIC) platform. However, the Near-RT RIC has, so far, been demonstrated to support …

Learning and Reconstructing Conflicts in O-RAN
… Intelligent Controller (Near-RT RIC), known as xApps, may result in conflicting interactions. Each xApp can independently modify the same control parameters to achieve distinct outcomes, which has the potential to cause performance degradation and network instability. The current conflict …

Strengthening Security Foundations in Next-G Wireless Telecommunication Systems
… analyzing eXtended Applications (xApps) to identify vulnerabilities, and secondly, an approach for conducting comparative assessments of these vulnerabilities. Additionally, a strategy is proposed to ensure that only secure xApps, such as those that have been pre-tested, are …

Interference Avoidance and Mitigation in 5G and Beyond Networks
… to achieve the desired capability. O-RAN xApps add intelligence to the RAN with seamless integration. Hence, we present a frequency agility xApp that provides E2SM control actions to the E2 node initiating swift user offloading between cells operating at different center frequencies or …

Design of Secure Scalable Frameworks for Next Generation Cellular Networks
… and the accompanying Extensible Applications (xApps). The introduction of these entities expands the 5G threat surface. Furthermore, with the movement from proprietary hardware to virtual environments enabled by NFV, attack vectors that exploit the existing NFV attack surface pose additional …
