  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 network management flexibility.
However, control decision conflicts occur when components from different
vendors are deployed together. This article provides an overview of various
types of conflicts that may occur in Open RAN, with a particular focus on
intra-component conflict mitigation among Extended Applications (xApps) in the
Near Real Time RAN Intelligent Controller (Near-RT-RIC). A QoS-Aware Conflict
Mitigation (QACM) method is proposed that finds the optimal configuration of
conflicting parameters while maximizing the number of xApps that have their
Quality of Service (QoS) requirements met. We compare the performance of the
proposed QACM method with two benchmark methods for priority and non-priority
cases. The results indicate that our proposed method is the most effective in
maintaining QoS requirements for conflicting xApps.
