Functional Split Options for 5G Networks As network architects work to meet the 5G challenges of increased traffic and data flows, a fundamental question is how much intelligence to put near the antenna versus at the DUs or CUs. Mobile Network Operators (MNOs) as well as industry-standards groups, such as the 3GPP, IEEE, Telecom Infra […]

The main motive for the RAN Intelligent Controller (RIC) is to bring software-defined controllability to RAN to increase system performance as on the path towards 5G, with network densification, and availability of different types of spectrum bands, it is increasingly a more difficult task to optimally allocate radio resources, implement handovers, manage interference, balance load […]

The O-RAN Alliance is the main driver of the OpenRAN concept, especially the efforts to standardize interfaces, in addition to the TIP. Founded in 2018 by AT&T, China Mobile, Deutsche Telekom, NTT DOCOMO, and Orange. The O-RAN Alliance’s goal is to foster the development of reference designs and standards such that current and future RANs […]

O-RAN SC architecture follows O-RAN Alliance defined architecture. In the O-RAN architecture, the radio side includes Near-RT RIC, O-CU-CP, O-CU-UP, O-DU, and O-RU. The management side includes Service Management and Orchestration Framework that contains a Non-RT-RIC function. Components Definition near-RT RIC: O-RAN near-real-time RAN Intelligent Controller: a logical function that enables near-real-time control and optimization […]

The “Cherry” Release of O-RAN Open Software  • Cherry features significant advancements in the end-to-end integration of O-RAN Architecture components. • The software now contains new functions aligned with the latest O-RAN specifications, such as the E2, A1 or O1 interfaces. In December 2020, the O-RAN Software Community (OSC), working with the Linux Foundation, published […]
