A recently granted patent (Publication Number: US11889508B1) discloses a system for managing a cellular network based on Open Radio Access Network (O-RAN) standards. The system includes an O-RAN distributed unit (O-DU) that generates control-plane messages for radio resource allocation, an interposer unit for managing radio resources, and an O-RAN radio unit (O-RU) for handling user-plane messages. The interposer unit plays a crucial role in monitoring the carrier signal, detecting interference sources, enabling synchronization measurements between cell sites, facilitating location determination of user devices, and identifying misconfigurations or cross-talk within the network. The system optimizes resource allocation and enhances network performance by efficiently managing radio resources and ensuring seamless communication between network components.

Furthermore, the patent also covers a method and a non-transitory computer-readable medium for implementing the system in a cellular network following O-RAN standards. The method involves receiving control-plane messages, generating user-plane messages, and monitoring the carrier signal for interference sources. By utilizing the allocated radio resources effectively, the method enables location determination of user devices, facilitates communication between network devices, and ensures efficient management of the network. The computer-readable medium stores instructions for controlling the process, emphasizing the importance of proper resource allocation, interference detection, and network optimization. Overall, the patent provides a comprehensive solution for managing cellular networks based on O-RAN standards, enhancing network efficiency, and improving user experience through optimized resource utilization and effective interference management.
